s101: and acquiring a transmission signal, and judging whether the transmission signal is matched with any preset terminal identification.
S102: and if the transmission signal is matched with any one of the preset terminal identifications, starting a current positioning device to position the terminal sending the transmission signal.
The terminal is equipped by the staff, and the terminal can carry out data communication with positioner between to fix a position the terminal by positioner, for example terminal and positioner adopt the RFID chip to communicate, the bluetooth communicates, WIFI communicates etc. positioner carries out the operation of distance, the operation of relative position thereby can confirm the concrete position of terminal through the operation of predetermined algorithm execution distance.
The preset terminal identifier may be pre-stored, and therefore, before step S101, the method may further include: acquiring terminal identifications of all terminals as preset terminal identifications, wherein each terminal is held by a worker entering the intelligent construction site; each terminal is provided with a unique terminal identification different from other terminals, and the terminal identification of each terminal is associated with the identity of the holder. For example, the identities of the terminals of all the workers who may enter the work site are first obtained as the preset terminal identities. Preferably, a security inspection device is arranged at an entrance of the intelligent construction site, and identifies identities of workers entering the construction site, so that related information of all workers entering the construction site can be confirmed, terminal identifications of the identities of all workers entering the construction site can be associated, and the terminal identifications which can be associated are used as preset terminal identifications.
The above steps of the scheme can be applied to a component for executing data communication, that is, a normal work flow is that a terminal sends a signal to a communication component, the communication component sends the signal to a positioning device, and the positioning device positions the terminal. Communication components such as bluetooth, WIFI all are the module that the consumption is less, and positioner has bigger consumption owing to need set up the processing chip that the operation was used etc. from this, adopts above-mentioned scheme for the state that positioner of prior art was opened always, has lower consumption, can practice thrift the electric quantity.
Further, as shown in fig. 2, the above scheme may further include the following steps:
s103, if the transmission signal matched with any preset terminal identification is not received in a preset time length, the positioning device is controlled to enter a dormant state. The preset time period may be selected to be 1-3 minutes.
Preferably, the output of the communication component is directly connected to an input of the pointing device, which is configured as an interrupt wake-up of the pointing device. When the interrupt awakening end receives the signal, the positioning device can be recovered to the working mode from the sleep mode. The communication assembly is used for receiving the transmission signal, analyzing the terminal identification in the transmission signal, matching the analyzed terminal identification with the preset terminal identification, and outputting a starting signal to the positioning device when the terminal identification is matched with the preset terminal identification. After receiving the signal, the positioning device restores from the sleep mode to the working mode. Therefore, the scheme can realize the ultra-low power consumption operation, namely, only the communication assembly works in the standby state, and other equipment parts are in the dormant state.
Further, as shown in fig. 2, the method may further include the following steps:
and S104, the positioning device sends the position information of the terminal sending the transmission signal to a server, wherein the position information comprises the current time, the current position and the identifier of the terminal. And the positioning device associates corresponding information and sends the associated information to the server after acquiring the specific position of the terminal, so that the server draws the running track of the terminal to obtain the running track. It can be understood that in the intelligent construction site, the positioning devices proposed in the scheme are multiple, and each positioning device can position a nearby terminal and send a positioning result to the server. And the server draws the mobile reply of each terminal respectively according to the terminal positioning results sent by all the positioning devices.
And S105, if the positioning device detects that the distance between the terminal sending the transmission signal and the positioning device is smaller than a set threshold value, acquiring a video in a detection area and sending the video to the server. The video result detected by the positioning device can comprise relevant information of staff holding the terminal, and then the server can judge the face recognition result in the video to determine whether the staff is corresponding, so that the situation that someone gives the terminal to other staff and does not enter a construction site is avoided.
