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

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.

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.
