The reserve resource checking unit is used for checking the material reserve amount in the reserve resource pool according to the received project material inventory of the project and determining the actual required quantity of the project. And the plan determining unit is used for forming purchasing information containing the actual engineering project demand quantity according to the checking result of the reserve resource checking unit, and correspondingly storing the purchasing information and the engineering project information of the related engineering project to form a monthly reserve plan. After the material reserve amount in the resource pool is checked, the monthly reserve plan can be reasonably determined, and excessive material purchasing is avoided.

The expert database stores the information of the expert terminals, and the expert database stores all the expert terminals in a classified manner according to the examination direction according to the expert excellence field. The expert database stores business expert side information and technical expert side information. And the business expert end mainly carries out information integrity and purchasing information normative examination on the monthly reservation plan. The technical expert information is mainly used for carrying out technical compliance examination on the monthly reserve plan.

Specifically, the task allocation module comprises a task acquisition unit, an expert query unit and a task allocation unit. And the task acquisition unit is used for acquiring the project information in the monthly reservation plan and acquiring the approval level of the corresponding project. In one embodiment, the project projects of national level, provincial level, prefecture level and county level can be directly obtained by the project names. In another embodiment, the approval level of the engineering project may be obtained by comparing the name of the engineering project with the approval level table. The examination and approval grade table is a table pre-stored in the system, and the table stores examination and approval grade information corresponding to engineering projects of national level, provincial level, local level city and county level city. And the expert inquiry unit is used for inquiring the expert end which accords with the examination and approval qualification of the engineering project in the expert library according to the examination and approval grades. And determining whether the expert is a business expert or a technical expert to conduct targeted examination according to the information of the job in the expert end information, and determining the expert whose examination and approval meets the examination and approval qualification of the engineering project according to the project processing information in the expert end information, or determining the examination and approval qualification according to the title information in the expert end information. The project processing information can reflect the approval qualification of which grade project the expert has to approve, and the approval qualification is determined according to the project processing information processed historically. And the task allocation unit is used for sending an examination instruction to the expert end to examine and approve the monthly reservation plan of the corresponding engineering project. The examination instruction comprises an examination level, an examination scope and an examination right. The examination level is divided into a group leader level and a common level, and the group leader level and the common level respectively have corresponding examination authority, the group leader level has authority for distributing an expert examination range in a group, comprehensive examination and signature authority, and the common level has the examination authority and the signature authority in the examination range. The examination range is determined according to the examination field of an expert end, the examination range of business experts is limited to information integrity and purchasing information normative examination, and the examination range of technical experts is limited to technical compliance examination. The system sends the examination instruction to the corresponding expert according to the communication contact information of the expert, such as e-mail or mobile phone number. And after receiving the examination instruction at the terminal, the relevant experts confirm examination at the terminal and enter a system interface for examination. When the expert is busy in work, the expert feeds back information which does not receive the examination instruction to the system at the terminal, and the task distribution module re-executes the distribution task.

Specifically, the expert review module comprises a business review unit and a technical review unit. And the business examination unit is used for the expert end to examine the information integrity and the purchasing information normalization of the monthly reservation plan according to the information integrity rule and the purchasing information normalization rule. The information integrity rule includes whether the information in the monthly reservation plan is missing, if the "Null" exists, the business examination unit feeds back the abnormal examination information, and the information integrity rule also includes the condition that the information in the monthly reservation plan is filled in by mistake (determined according to the filling range standard). For example, if the purchasing information lacks national standard materials, the business examination 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 business examination 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 after the business examination unit passes the examination, triggering the technical examination unit to work. For another example, the technical review unit is used for an expert end to review the technical compliance of the monthly reservation plan according to the technical standard rules pre-stored in the power grid material review 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 rule audit library also stores operation order rules. The expert examination module also comprises an operation ticket examination unit which is used for an expert end to examine whether the operation tickets conform to the operation ticket rules one by one. The operation ticket checking unit is triggered after the technical checking unit passes the checking. The operation ticket examination is also carried out by assigning corresponding technical experts by the task assignment module. When the operation ticket checking unit is executed, an expert is required to check the operation ticket rule one by one at the terminal. The operation order rule mainly refers to rules in the aspect of electrical operation, such as checking whether materials are in a certain agreement stock bill of materials, checking whether the materials belong to a preferred material library in a certain grade power grid standard library, and the like, checking whether reporting of national grid equipment batches is allowed, and checking whether the preferred materials can be selected according to the size on the premise that design conditions are met. Compared with the business examination unit and the technical examination unit, the operation ticket examination unit needs to be combined with experience knowledge of an expert. The first two units are more focused on self-service examination in the system, and automatic matching examination is carried out according to the existing rules.

The rule examination library also stores price rules, and the expert examination module also comprises a price examination unit which is used for an expert end to examine the purchase price of the purchase information in the monthly reservation plan according to the price rules prestored in the power grid material examination system. The price examination unit is triggered after the operation ticket examination unit passes examination. The expert information also includes project manager information for checking the purchase price (including unit price, quantity, total price) in the monthly reservation plan. The price rules store prices for each type of material (unit prices to meet national grid reference price tables), and allowed purchase quantities (e.g., which materials need to be purchased in pairs/packages). In addition, the project manager also needs to review the delivery time rules in the monthly reservation plan for configuring the delivery date of materials, for example, the earliest delivery date of the general equipment materials with automatic assignment according to the batch information, the latest delivery date of the tower (including the substation framework bracket), the latest delivery date of the ground wire, the main transformer, the earliest delivery date of the GIS, and the like.

The system also comprises a batch management module and a final examination module. The batch management module is used for storing a purchasing batch list. And the purchasing batch list is correspondingly stored according to the year, the batch name, the purchasing mode, the purchasing category and the batch list. The batch inventory stores project material inventory and technical specifications of corresponding project projects. And the final examination module is used for matching the monthly reservation plan examined by the expert examination module with a purchasing batch list in the batch management module according to the purchasing mode and the purchasing category in the purchasing information, if so, associating the monthly reservation plan with a corresponding batch, otherwise, adding a new batch in the purchasing batch list, and associating the monthly reservation plan with the new batch. After passing the expert review, the system of the present invention generates the batch requirements and performs the final review (see in particular the review flow shown in fig. 3). The batch requirement generation is to generate a procurement batch so that the next procurement execution can be performed.

Specifically, the final-review module includes a batch matching unit and a requirement merging unit. And the batch matching unit is used for matching the monthly reservation plan reviewed by the expert review module with a purchase batch list in the batch management module according to the purchase mode and the purchase category in the purchase information, associating the batch obtained by matching with the monthly reservation plan, and entering the demand merging unit. Otherwise, adding a new batch in the purchase batch list, associating the monthly reservation plan with the new batch, and entering a demand adding unit. The batch can be a national network centralized tender purchasing batch, a provincial company centralized tender batch, a local company tender batch and the like. And the demand merging unit is used for matching the newly matched monthly storage plan in the project material inventory and the technical specification of the related projects stored in the batch according to the project information, matching to obtain the items of the same project information, and merging the demand quantity of the same materials in the purchase information. And the demand adding unit is used for storing the monthly reservation plan in the batch inventory under the condition of adding the batch. And (4) listing the purchasing requirements required by different projects into each batch for uniform purchasing. For those lots for which no match is found, a new lot is established for purchase. Because the material purchasing plan is many and the material purchasing content is many, if all purchase is carried out according to the project unit, the problems of complex examination and approval, low efficiency, inconvenient purchasing and the like exist, and once purchasing is carried out according to the batch, unified examination and approval and purchasing can be realized. Wherein, the purchase date is determined according to each batch, and the plurality of project units can report the purchase data (such as monthly reservation plan passing examination) in the specified batch reporting time, and can unify the planned purchase.

The final examination module also comprises a rechecking unit which is used for triggering the expert examination module to carry out the recheck when the batch matching unit does not match the batch for the first time, and when the expert examination module passes the rechecking, the batch matching unit carries out the batch matching. The review unit needs to count the number of times that the batch matching unit does not match the batch, if the monthly reservation plan declared by the project is not matched with the corresponding batch and is the first time, the monthly reservation plan needs to be returned to the expert review module (the expert needs to be redistributed for review during the review of the module) to perform the above review content on the monthly reservation plan, that is, whether the monthly reservation plan has a review error problem is reviewed, if not, the batch demand generation and the final review are sequentially performed after the monthly reservation plan is reviewed by the expert review module. For a monthly reservation plan that again does not match a lot, the plan is deemed to require the addition of a new lot to make the purchase.

The system of the present invention further includes an audit log module for storing audit data related to the monthly reservation plan that is audited by the basic audit module and the expert audit module. The examination log module can assist subsequent examination and examination processes, such as examination of unqualified content of a monthly reservation plan, and is convenient for a design end and a project end to inquire information and an expert end to inquire the reason of the unqualified examination in the previous time.
