The embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict.

The first embodiment is as follows:

the embodiment aims to provide a construction site safety supervision method,

a construction site safety supervision method comprises the following steps:

obtaining relevant vehicle information and constructor information of a construction site in advance, and constructing a two-dimensional scene model based on construction site data; marking a dangerous area in the two-dimensional scene model;

acquiring images of vehicles and personnel entering and exiting a construction site, and verifying the identities of the vehicles and the personnel based on an image recognition algorithm;

recording the action track of the constructors in real time based on RFID chips on the constructor safety helmets and RFID signal acquisition devices uniformly arranged in a construction site;

when detecting that the constructor enters the early warning range of the dangerous area, controlling an alarm device arranged in the dangerous area to carry out early warning, and realizing the safety supervision of a construction site.

Firstly, the implementation of the solution described in the present disclosure requires the following preparatory work to be performed in advance:

(1) construction of a scene model

Considering that a construction site is complex, scene change in the construction site is large along with increase of construction time, if a three-dimensional scene model is constructed, the three-dimensional scene model needs to be continuously adjusted along with increase of construction time, and work is complex, so that the construction site is modeled by the two-dimensional scene electronic map, and later modification is less and modification is convenient.

The construction site data-based two-dimensional scene model is constructed, specifically, a two-dimensional scene electronic map of construction site data is constructed according to a construction site ground layout map and various matched equipment and facility maps, and the positions of an RFID signal acquisition device and a dangerous area are marked on the two-dimensional scene electronic map.

(2) People and vehicle data statistics

This disclosure the scheme needs to make statistics to constructor and the relevant vehicle of construction site in advance, specifically as follows:

1) statistics of personnel data

For construction related personnel, relevant information such as faces, identity cards and the like of the participating personnel is collected and bound, and the participating personnel real-name management is realized by adopting three verification modes of face recognition, card swiping verification, face recognition and card swiping combination based on a face recognition terminal.

2) Vehicle data statistics

The intelligent chemical management platform records vehicle related information including license plate number, vehicle body color, vehicle model, vehicle affiliated unit, contact person and the like.

Secondly, acquiring images of vehicles and personnel entering and exiting the construction site, and verifying the identities of the vehicles and the personnel based on an image recognition algorithm; the method specifically comprises the following steps:

(1) person identification

For personnel (constructors and visitor personnel) entering and exiting a construction site, the entering time and the leaving time of all the personnel are automatically collected and recorded by compiling a corresponding program and combining a face recognition terminal, the entering personnel statistical information is formed, the functions of summarizing and analyzing the quantity of the personnel are realized, and a corresponding database is constructed to store the information.

Wherein, to visitor's personnel, adopt quick face-brushing to type in, only record simple information such as group and time. Establishing a WeChat two-dimensional code scanning code input, realizing that the WeChat two-dimensional code scanning code fills visitor information, and carrying out face recognition and then carrying out approval by a background auditor to realize quick face brushing and entering.

Furthermore, according to the scheme of the disclosure, an infrared automatic body temperature measuring device is added in the face recognition terminal, the body temperature of the entering personnel is rapidly detected, the alarm is given to the personnel with abnormal body temperature according to the body temperature threshold set by the system, and the alarm information is pushed to the related personnel.

(2) Vehicle identification

When a vehicle enters and exits, the vehicle data acquisition module acquires, analyzes, processes, stores and uploads vehicle data, the background management platform completes access, comparison, recording, analysis and sharing of vehicle data information, automatically completes recognition of vehicle license plates, recording of license plate numbers, vehicle body colors, entering/leaving time and the like, and the database is built through the background server for storage.

Further, in order to better manage and control the entering and exiting vehicles, in this embodiment, vehicle barrier devices are arranged at an entrance and an exit of a sub-packet area, an entrance and an exit of an office field of a general packet unit, and an entrance and an exit of a construction site, so that management and control of vehicle license plate information, attribution information and vehicle type information are realized.

The method comprises the steps of performing two links of vehicle registration and personnel registration on unregistered vehicles, binding vehicle information and personnel information, and defining a first person responsible for the vehicles. The vehicle access management carries out all-round management to vehicle access information, carries out intelligent inquiry, statistics, analysis according to the access data to and with video monitoring system, personnel management system's butt joint, organically integrate single data, form valuable data link, provide powerful support for the safe, efficient management in wisdom building site.

For fixed vehicles and temporary vehicles entering and exiting an item, relevant management and control strategies can be configured, and a vehicle blacklist can be set. Wherein, for a stationary vehicle: the license plate can enter the field when the identification and comparison are correct, and no operation is needed. For a scene with higher management and control requirements, the vehicle card is required to be consistent, namely, the vehicle can enter the scene only when the two authentication modes pass through simultaneously; for a temporary vehicle: the temporary vehicle clearance can be carried out in two modes of filling information by WeChat code scanning or card fetching by parking registration.

Further, acquiring images of vehicles and personnel entering and exiting the construction site, and verifying the identities of the vehicles and the personnel based on an image recognition algorithm; the image recognition algorithm may use an existing neural network-based algorithm (e.g., DBN, CNN, etc.), and since such an algorithm is relatively mature, it is not described herein again.

Further, the real-time recording of the action trajectory of the constructor specifically includes: the RFID signal acquisition device is used for acquiring the RFID information on the safety helmet of the constructor, and the action track of the constructor is determined according to the time sequence of the same RFID information acquired by the RFID signal acquisition devices at different positions based on the uniqueness of the RFID information. And recording the action tracks of the constructors, and when a safety accident occurs, determining the person responsible for the accident by comparing the action tracks. For example: if the fire disaster happens in the fire forbidden area of the construction site, the personnel entering the area in a specific time period can be inquired through the recorded personnel action track if the fire disaster is determined as a factor, and then the range of the investigation personnel can be effectively reduced.

Furthermore, when detecting that the constructor enters the early warning range of the dangerous area, the early warning device arranged in the dangerous area is controlled to carry out early warning, and the safety supervision of the construction site is realized. The early warning range is set according to the position of a dangerous area in the two-dimensional electronic map and a preset safety range, and when the RFID signal acquisition device at the position of the dangerous area obtains that a constructor approaches, the background server sends a signal to an alarm device of the dangerous area to perform early warning; meanwhile, the names of the construction personnel are determined through the collected RFID signals, and the management personnel conduct criticizing education in the later period, so that the problem that the construction personnel mistakenly enter a dangerous area and further cause personnel damage and unnecessary property loss is effectively avoided.
