Specifically, the primary unit examination module comprises a primary demand balance bank examination unit and a primary purchasing mode examination unit. The first-level demand balance interest bank examination unit is used for examining the first-level material purchasing request, carrying out first-level demand balance interest bank examination according to the first-level purchasing information, examining the material reserve quantity in the first-level unit reserve resource pool, determining the actual engineering project required quantity, and forming a new first-level material purchasing request. And then, the primary demand balance interest rate examination unit sends a new primary material purchasing request to a primary purchasing mode examination unit. The first-level purchasing mode examining unit is used for examining the purchasing mode of the first-level purchasing information in the new first-level material purchasing request: when the purchasing mode is single source purchasing or batch purchasing, a new primary material purchasing request is sent to a superior examination module; when the purchasing mode is authorized entrusted purchasing, a new primary material purchasing request is sent to the bid inviting purchasing module; and when the purchasing mode is protocol inventory purchasing, sending a new primary material purchasing request to the protocol inventory examination module. The process basically completes the first-level unit material purchasing request declaration flow chart (see fig. 2).

The first-level unit examination module also comprises a first-level unit demand unit, which is used for detecting whether the purchasing mode in the first-level purchasing information is protocol inventory purchasing or not when the first-level unit examination module receives a first-level material purchasing request, if so, merging the material demand quantity belonging to the protocol inventory purchasing, and if not, not merging; and then sending the combined primary material purchasing request or the uncombined primary material purchasing request to a primary demand balance interest bank examination unit. For example, the same materials in the national network agreement inventory are combined in the required quantity of the materials, and the same materials in the network province agreement inventory are combined in the required quantity of the materials.

Specifically, the secondary unit examination module comprises a secondary demand balance bank examination unit and a secondary purchasing mode examination unit. And the secondary demand balance interest bank examination unit is used for examining the secondary material purchasing request, carrying out secondary demand balance interest bank examination according to secondary purchasing information, examining the material reserve quantity in the secondary unit reserve resource pool, determining the actual engineering project demand quantity and forming a new secondary material purchasing request. And then, the secondary demand balance interest rate examination unit sends a new secondary material purchasing request to a secondary purchasing mode examination unit. The second-level purchasing mode examining unit is used for examining the purchasing mode of the second-level purchasing information in the new second-level material purchasing request: when the purchasing mode is single-source purchasing or batch purchasing, a new secondary material purchasing request is sent to the primary examination module, when the purchasing mode is authorized entrusting purchasing, the new secondary material purchasing request is sent to the bid inviting purchasing module, and when the purchasing mode is agreement inventory purchasing, the new secondary material purchasing request is sent to the primary examination module.

When the secondary purchasing mode is single-source purchasing or batch purchasing or agreement inventory purchasing, the primary examination module is required to be entered for examination. Therefore, the primary demand balance interest bank examination unit is also used for examining a new secondary material purchasing request, carrying out primary demand balance interest bank examination on secondary purchasing information of the new secondary material purchasing request, checking the material reserve quantity in a secondary unit reserve resource pool, determining the actual engineering project demand quantity and forming a secondary balance material purchasing request. And then, the primary demand balance profit bank examination unit sends a secondary balance material purchasing request to the primary purchasing mode examination unit. The first-level purchasing mode examining unit is also used for examining whether the purchasing mode of the second-level purchasing information in the second-level balancing material purchasing request is protocol inventory purchasing, if so, sending the second-level balancing material purchasing request to the protocol inventory examining module, and if not, sending the second-level balancing material purchasing request to the higher-level examining module. The process basically completes the flow chart of the declaration of the secondary unit material purchasing request (see fig. 3).

The second-level unit examination module further comprises a second-level unit demand unit, and the second-level unit demand unit is used for detecting whether the purchase mode in the second-level purchase information is protocol inventory purchase or not when a second-level material purchase request is received, merging the material demand quantity belonging to the protocol inventory purchase if the purchase mode in the second-level purchase information is the protocol inventory purchase, and not merging the material demand quantity if the purchase mode in the second-level purchase information is the protocol inventory; and then sending the combined secondary material purchasing request or the uncombined secondary material purchasing request to a secondary demand balance interest bank examination unit. For example, the same materials in the national network agreement inventory are combined in the required quantity of the materials, and the same materials in the network province agreement inventory are combined in the required quantity of the materials.

And the superior examination module is used for examining a new primary material purchasing request and a secondary balance material purchasing request, and generating purchasing data after examining and passing financial budgets. Taking the first-level material purchasing request as an example, the purchasing information in the first-level material purchasing request is examined and approved, and the financial examination and approval, the item WBS information examination and the approximate calculation examination are sequentially carried out on the purchasing quantity and the purchasing price. And checking the national network reference price list in the checking process, checking whether the national network reference price list accords with the current annual budget/current month/current season budget, forming specific purchasing data after the checking is passed, and sending the specific purchasing data to a third-party supplier for purchasing. Likewise, secondary balance material procurement requests are reviewed as well.

And the agreement inventory examination module is used for examining a new primary material purchasing request and a new secondary balance material purchasing request and generating purchasing data after the examination is passed. The agreement stock comprises a plurality of types, each agreement stock already determines a corresponding supplier when an agreement is signed, and for this purpose, by determining the agreement stock type of the material required to be purchased, purchasing data of the corresponding supplier is formed and sent to the supplier.

And the bid inviting and purchasing module is used for examining the new primary material purchasing request and the new secondary material purchasing request and generating purchasing data after the examination is passed. The bid inviting purchasing module specifically comprises a material purchasing demand unit and a bid inviting purchasing unit. The material purchasing demand unit is used for classifying the purchasing materials of the first-level material purchasing request or the new second-level material purchasing request and performing different bid purchasing according to the material types. Wherein, the materials which are purchased in a matching way need to be purchased in a unified way. And after the classification of the material purchasing demand unit is finished, sending the material purchasing demand unit to a bid purchasing unit to perform bid purchasing according to the material category. The tender purchasing module further comprises a supplier unit, and the supplier unit stores a supplier list and materials corresponding to the material categories. And the tender purchasing unit tenders the corresponding materials to the related suppliers according to the storage information of the supplier unit to form purchasing data of the corresponding suppliers and sends the purchasing data to the suppliers.

The system also comprises a first-level unit reserve plan examination module which is used for examining the first-level unit reserve plan sent by the market-level demand end and sending examination qualified information to the market-level demand end after the examination is passed. The city-level demand end sends a first-level material purchasing request to a first-level unit declaration module based on a first-level unit reserve plan. The primary unit reserve plan comprises a project material inventory and a technical specification corresponding to the primary unit project. The engineering material inventory comprises material codes, technical specification IDs and required quantity. And the city level design unit designs the project entrusted by the project unit to complete the project material inventory, and the project unit audits the project material inventory. After the audit is passed, the data are reported to the market-level material department to form a first-level unit reserve plan.

Specifically, the primary unit reserve plan examination module comprises a rule examination library and a primary unit examination unit. The rule examination library is used for storing information integrity rules, purchasing information specification rules and technical specification rules. The information integrity rule mainly indicates whether a level unit reserve plan is complete or not and whether engineering project information and purchasing information are complete or not. The information integrity rule is set based on the information contained in the unit-of-class reserve plan. The purchasing information standard rule is mainly determined according to a purchasing catalogue, and whether purchasing information is set according to the purchasing catalogue is determined. The technical specification rule is a technical rule set according to national standards, and the design meeting the regulations is required to be carried out on projects with different voltage levels. The first-level unit examination unit is used for calling examination rules in the rule examination library, examining the monthly storage plan of the first-level unit for information integrity, purchasing information standardization and technical compliance, if the examination is passed, sending examination qualified information to the market-level demand end, and if the examination is not passed, sending examination unqualified information to the market-level demand end. The information integrity rule comprises whether the information in the primary unit reserve plan is missing, if the Null exists, the primary unit examination unit feeds back the abnormal examination information, and the information integrity rule also comprises the condition that the information in the primary unit reserve plan is filled in by mistake (determined according to the filling range standard). For example, if the procurement information lacks national standard materials, the primary unit review unit feeds back material normative abnormal information. For example, if the filling range of the project voltage class is 500 kV, 220kV, 110kV, 35 kV, and the actually declared voltage class is 111 kV, the first-level unit review unit feeds back information to fill the normative abnormality information. The purchasing information specification rules comprise rules whether the material subclass, the medium class and the large class are in the purchasing catalogue. The purchasing catalog is formed by the corresponding relation table of purchasing category and material classification, and is indexed by material code. The first-level unit examination unit also examines the technical compliance of the monthly reservation plan according to the technical standard rules prestored in the power grid material examination system. For example, for the requirement of the subclass of capacitor bank series reactor', the material description contains hollow, the number of the hollow is 3 times of the required number of the subclass of frame-type capacitor bank or integrated capacitor bank under the same engineering, the material description contains iron cores, and the number of the hollow is consistent with the required number of the subclass of frame-type capacitor bank or integrated capacitor bank under the same engineering. For another example, the subclass is "grounding transformer", the material description includes "10 KV", the requirement corresponds to the requirement of the subclass of the engineering name including "arc suppression coil", and the two requirements should be the same solidification ID. Also for example, the subclass is "capacitor bank series reactors", which cannot be purchased separately. The requirements under the engineering name should include a subclass of "collective capacitor bank (without reactor)" or "frame capacitor (without reactor)", and the two requirements should be the same curing ID. Such as the above example, the technical specification rules are set according to the national standard, and the technical specification rules are set according to different national standards according to the design project specification and grade.

The system also comprises a secondary unit reserve plan examination module which is used for examining the secondary unit reserve plan sent by the county level demand end and sending examination qualified information to the county level demand end after the examination is passed. And the county-level demand end sends a secondary material purchasing request to the secondary unit declaration module based on the secondary unit reserve plan. The secondary unit reserve plan comprises a project material inventory and a technical specification corresponding to the secondary unit project. The engineering material inventory comprises material codes, technical specification IDs and required quantity. And the county level design unit designs the project entrusted by the project unit to complete the project material inventory, and the project unit audits the project material inventory. And after the audit is passed, reporting the data to a county level material department to form a secondary unit reserve plan.

Specifically, the secondary unit reserve plan examination module comprises a rule examination library and a secondary unit examination unit. The rule examination library is used for storing information integrity rules, purchasing information specification rules and technical specification rules. The content stored in the rule checking library is basically similar to that of the rule checking library of the first-level unit reserve plan checking module, the only difference is that the grades of the accessed projects are different according to the county-level and city-level qualities, and the rule standard is determined according to the project grades. That is, the rule checking library of the secondary unit reserve plan checking module does not store the high standard rule of the project which can be accepted by the primary unit. The rule checking library of the first-level unit reserve plan checking module can store the rule that the first-level unit and the second-level unit can both receive the project, or only store the high-standard rule that the first-level unit can receive the project. And the secondary unit examination unit is used for calling examination rules in the rule examination library, examining the monthly storage plan of the secondary unit for information integrity, purchasing information standardization and technical compliance, if the examination is passed, sending examination qualified information to the county level demand end, and if the examination is not passed, sending examination unqualified information to the county level demand end. The information integrity rule comprises whether the information in the secondary unit reserve plan is missing, if the Null exists, the secondary unit examination unit feeds back the abnormal examination information, and the information integrity rule also comprises the condition that the information in the secondary unit reserve plan is filled in by mistake (determined according to the filling range standard). For example, if the procurement information lacks national standard materials, the second-level unit review unit feeds back the material normative abnormal information. For example, if the filling range of the project voltage class is 500 kV, 220kV, 110kV, 35 kV, and the actually declared voltage class is 111 kV, the second-level unit review unit feeds back information to fill the normative abnormality information. The purchasing information specification rules comprise rules whether the material subclass, the medium class and the large class are in the purchasing catalogue. The purchasing catalog is formed by the corresponding relation table of purchasing category and material classification, and is indexed by material code. And the secondary unit examination unit also examines the technical compliance of the monthly reservation plan according to a technical specification rule prestored in the power grid material examination system. For example, for the requirement of the subclass of capacitor bank series reactor', the material description contains hollow, the number of the hollow is 3 times of the required number of the subclass of frame-type capacitor bank or integrated capacitor bank under the same engineering, the material description contains iron cores, and the number of the hollow is consistent with the required number of the subclass of frame-type capacitor bank or integrated capacitor bank under the same engineering. For another example, the subclass is "grounding transformer", the material description includes "10 KV", the requirement corresponds to the requirement of the subclass of the engineering name including "arc suppression coil", and the two requirements should be the same solidification ID. Also for example, the subclass is "capacitor bank series reactors", which cannot be purchased separately. The requirements under the engineering name should include a subclass of "collective capacitor bank (without reactor)" or "frame capacitor (without reactor)", and the two requirements should be the same curing ID. Such as the above example, the technical specification rules are set according to the national standard, and the technical specification rules are set according to different national standards according to the design project specification and grade.
