After the deployment of the intelligent terminal equipment of the access channel is completed, it is connected to the cloud server, and the intelligent terminal equipment of the access channel can be added to the current project; when adding the project, it is necessary to fill in the following: equipment number, equipment name, equipment deployment coordinates according to actual requirements; after successfully joining the project, the electronic fence, electronic fence sub-area of ​​the current construction site, and the working status of each intelligent terminal equipment of the access channel can be clearly displayed in the project map in the visualization display module (in the embodiment of the present application, the intelligent TV device at the monitoring end uses the monitoring large screen as the visualization display module).

[0078] When construction workers enter the site for the first time, they need to perform real-name authentication through the smart entry terminal, then open the entry and exit QR code in the smartphone APP and scan the code to enter, which specifically includes the following steps S2.1-S2.5.

[0079] S2.1. After the construction company confirms the cooperative construction party, it invites the construction company's labor manager to join the platform cooperation project through text messages in the smartphone APP; the labor manager completes the account registration through the mobile phone number and authenticates the current company information to complete the account joining the project process.

[0080] S2.2. In the smartphone APP, the labor administrator uses the construction worker invitation module in the smartphone APP to invite construction workers who need to enter the site for the current construction project to the current project, and sets basic information such as the type of work corresponding to each construction worker.

[0081] S2.3. After receiving the SMS invitation on the user's smartphone device, the invited construction worker clicks on the link in the SMS to download the smartphone APP to complete the account registration and automatically enters the construction project. At this time, an identity identification code can be generated.

[0082] Advantages: The combination of software and hardware can help managers invite construction personnel to join the project in a convenient way anytime and anywhere. The advantage of anytime and anywhere is that there is no need for personnel to be present in person. Only text messages can be used to allow qualified personnel to join the project. During the process of joining the project, the identity can be confirmed by comparing the person with the ID card.

[0083] Current situation: Management personnel are required to lead construction personnel to the project site to queue up and register to join the project. Complex operations such as taking photos, filling out forms, and entering basic personnel information are also required.

[0084] S2.4. Construction workers go to the construction site with their ID cards and enter the entrance channel in turn. The smart entrance terminal on the three-wheel gate (or full-height gate) of the entrance channel and the ID code of the construction worker's user smartphone device will verify whether the construction worker is the current project worker. After confirming the identity, the ID card information of the construction worker entering the site for the first time will be collected, and they will be allowed to pass after completing the facial recognition authentication; workers who are not entering the site for the first time will be released directly.

[0085] Advantages: All intelligent terminal devices for entry and exit channels can be used in conjunction with users' smartphones to complete the entire process of identity registration, real-name authentication, face recognition, and face information collection. No professional cooperation is required. Construction personnel can operate independently according to the voice prompts of the entry intelligent terminal. Multiple sets of equipment on site can be used simultaneously, solving the queuing problem caused by a single device for collection in the traditional mode. Temporary entrants can enter the venue independently.

[0086] Current situation: At present, construction workers need to be led by labor personnel to the office work area of ​​the general contractor's project site before they can enter the site. A device will input the identity information and complete the employee's real name, and then input the face. The whole process is long and cumbersome. Construction workers frequently enter and exit the site, and the personnel are mixed. Real-name authentication and record keeping require the cooperation of a professional. Often, one or two people cannot enter the site directly, and a certain number of people need to gather to log in uniformly.

[0087] S2.5. An infrared sensor is installed at the end of the entrance channel. After the infrared sensor confirms that the current construction worker has passed, it notifies the cloud server to send a positioning activation command to activate the positioning function of the construction worker's smartphone APP; at this time, the specific location information of the construction worker in the venue is uploaded.

[0088] Advantages: A sensor device is set at the end of the channel, which can be activated after the identity verification of the personnel is successful. When the sensor device senses the person passing through, the cloud server will record the accurate record of the person's entry, eliminating the situation where the face recognition is successful but the person fails to enter. When the construction personnel enter the site effectively, the positioning function of the smartphone APP is activated, and the location trajectory of the construction personnel can be tracked without the need for external devices.

[0089] Current situation: At present, the site management only uses face recognition for entry. After the face recognition is successful, the site equipment considers that the person has entered the site, but it is not certain whether the person has left after the face recognition. In addition, when locating construction workers by face recognition, they need to use peripherals: wearable positioning bracelets and positioning safety helmets to locate and track the construction workers. These devices are expensive and difficult to maintain. At the same time, such peripherals may be used interchangeably, and the positioning is often successful but the basic information of the construction workers is inaccurate.

[0090] S2.6. The smart TV device at the monitoring end uses a large monitoring screen as a visual display module. In the electronic fence map displayed, the specific location information of the construction workers and the historical trajectory of their activities are displayed on the map in the form of bubbles with their head portraits. These location information are counted by the cloud server to obtain statistical information including: the current number of people on site, the number of people entering the site today, the number of people in the project, the distribution of work types, the list of people on site for the longest time, the trend of the cumulative number of people in the project, etc.

[0091] Advantages: The monitoring screen is uniformly equipped in the form of modules, and only the intelligent terminal equipment of the entry and exit channels is used to activate the positioning of the construction personnel's smartphone APP. The monitoring screen can be used for projects of all sizes. Its biggest advantage is that the management personnel can intuitively see all kinds of real-time data and personnel status at the construction site through the monitoring screen.

[0092] Current situation: At present, there is no large monitoring screen in the construction site management. The large monitoring screen is often expensive. When a small-cost and low-scale construction site needs such a large monitoring screen to display some real-time data of the construction site, there is no additional funds to develop and use it.

[0093] When an accident occurs at the construction site, construction workers or administrators can use the following functions of the smartphone APP: one-click rescue, one-click site clearance notification, personnel trajectory tracking, electronic emergency plan execution and other personnel safety emergency protection functions. For details, see 3.1-3.3.

[0094] 3.1. The role of one-button help and electronic emergency plan: To use this function, you need to install a smartphone APP on the user's smartphone device. When the positioning function of the smartphone APP is activated, the one-button help button is activated from the original prohibited state to the standby state. When construction workers encounter or discover danger, they can click this button. After receiving the trigger signal of the button, the cloud server can automatically generate an emergency plan based on the number and location distribution of construction workers who triggered the one-button help button. You can also select based on the pre-selected emergency plan. At this time, the cloud server gives several danger options preset by the system, such as: fire, individual trapped, group trapped, etc.; each danger category corresponds to a set of electronic emergency plans, but this method is less flexible and adaptable than the aforementioned method of automatically generating emergency plans.

[0095] After the emergency plan is generated or selected, the cloud server executes the emergency plan and notifies all relevant personnel of the emergency plan of the rescue signal of the person in need of help through three methods: message push on the smartphone APP, text message, and phone call. The emergency plan is also pushed, texted, and played to the recipient in accordance with the preset content of the emergency plan. The recipient executes the corresponding rescue measures according to the corresponding emergency plan.

[0096] 3.2. The role of the one-click clearing button in an accident: When a dangerous situation occurs on the site, the manager or the executor of the emergency plan can use this function to quickly and conveniently notify all construction workers on the site to leave quickly. The system automatically determines whether anyone in the current site has clicked the help button. If so, the manager clicks the one-click clearing button, and the system automatically generates a set of notification texts according to the type of dangerous situation triggered to inform all construction workers to leave the site. At the same time, after receiving this notification, the construction workers can view the specific location of the current dangerous situation and bypass this dangerous area when leaving the site to prevent secondary injuries. If there is no SOS button in the venue and the manager clicks on one-click to clear the venue, only a general evacuation notice will be generated, and the specific location of the danger will not be displayed on the map of the smart TV terminal APP; when the location information of the construction worker does not change after receiving the clearance notice, the system determines that the construction worker may be in a state of not receiving the notification. At this time, the system initiates a telephone notification, inquiring about the safety status of the construction worker, and asking the construction worker to execute the clearance operation; if no one answers the telephone inquiry, the management personnel will be notified whether to list the construction worker as an injured person to be rescued, and the system background will mark the location information of this construction worker; when the safe and uninjured construction personnel execute the evacuation and leave the venue normally through the entry and exit channel, the exit smart terminal on the channel will send the information of the exit personnel to the cloud server, and the cloud server will turn off the positioning function of the construction personnel's user smartphone device; and update the list of people on site. At this time, the people left out of the venue are the trapped people.

[0097] 3.3. The decision-making role of the monitoring center TV (i.e., the smart TV device at the monitoring end) in accidents: When a dangerous situation occurs on site, the TV in the monitoring center will flash repeatedly in a striking red color, and display the specific location, name, phone number, and subcontractor or general contractor of the current distress signal in the center of the TV; and display the type of the current distress signal: fire, individual trapped, group trapped, etc.; when the manager initiates a one-click site clearance notice, the movement trajectory of all construction personnel can be seen on the monitoring center TV, and the execution status of the site clearance and evacuation notice can be checked in real time; every time a construction worker leaves the site safely, the list of on-site personnel is reduced by one, and after the final site clearance and evacuation work is completed, the remaining personnel in the site are all trapped persons; through the data displayed on the monitoring center TV.
