In this embodiment, the mobile terminal 110 is a wireless location terminal of a factory personnel location system with location application software installed, including but not limited to an explosion-proof cell phone, such as an intrinsically safe explosion-proof cell phone. The anti-explosion mobile phone is a special mobile phone designed for meeting the communication needs of workers in flammable and explosive places, improves the transmission efficiency and accuracy of information through data feedback, and realizes the circulation, management and control of production data and equipment state information. With the development and popularization of the internet of things technology, the anti-explosion mobile phone is widely applied to the industrial automatic production process, a positioning system is installed in the anti-explosion mobile phone to position personnel without carrying a positioning instrument, and the accurate positioning of the personnel in the factory indoor/outdoor environment can be realized based on the positioning, data processing and data transmission devices of the anti-explosion mobile phone, so that the production cost is reduced.
The positioning processing module 111 is a data processing module in the mobile terminal 110, for example, a central processing unit (CentralProcessingUnit, CPU), one interface of the positioning processing module 111 is connected with one interface of the indoor positioning module 112 through a wire, for example, the indoor positioning module 112 is a bluetooth positioning module, the other interface is connected with one interface of the outdoor positioning module 113 through a wire, and the outdoor positioning module 113 may be a global satellite navigation system (Global Navigation Satellite System, GNSS) positioning module, for example, a global positioning system (Global Positioning System, GPS) module. The positioning information is real-time location information of a person carrying the mobile terminal 110. The mobile terminal 110 is equipped with a positioning process, which can control the acquisition and transmission of positioning information.
Specifically, a positioning process in the mobile terminal 110 is started, the indoor positioning module 112 and/or the outdoor positioning module 113 are controlled to collect positioning data, the positioning data is transmitted to the positioning processing module 111 through wired communication, the positioning processing module 111 packages the positioning data and transmits the positioning data to the positioning engine server 120 in a wireless mode, the positioning engine server 120 determines the area where the personnel are located according to the positioning data, and the positioning processing module 111 controls the outdoor positioning module 113 to be turned on and off based on the positioning data collected by the indoor positioning module 112.
Illustratively, according to the daily activity range of factory personnel, the area is divided into three parts of a factory indoor part, a factory outdoor part and a factory outdoor part, and the sizes of the various areas can be flexibly defined according to actual scenes. The positioning processing module 111 analyzes the positioning information identified by the indoor positioning module 112, and if the personnel are determined to be located in the indoor area of the factory, the working state of the outdoor positioning module 113 is set to be closed; if it is determined that the person is located in the outdoor area of the factory, the working state of the outdoor positioning module 113 is set to be on; if it is determined that a person is located in an off-site area, the operating state of the outdoor location module 113 is set to off.
In order to save power consumption of the mobile terminal 110 and prolong standby time, optionally, the positioning processing module is specifically configured to switch the working states of the indoor positioning module and/or the outdoor positioning module based on the trend of the personnel track when the personnel is determined to be located in the transition area based on the positioning information.

In this embodiment, the preset history period is a period in which positioning information is acquired multiple times before a preset current time point.
Specifically, the mobile terminal 110 packages the positioning information collected by the indoor positioning module 112 and the outdoor positioning module 113 into a positioning data packet, sends the positioning data packet to the positioning engine server 120, and the positioning engine server 120 analyzes the positioning data packet to obtain positioning information and stores the positioning information according to time. If the Major obtained by the positioning engine server 120 parsing the positioning data packet characterizes that the installation location of the current beacon is in the transition area, it may be considered that the person carrying the mobile terminal 110 is located in the transition area. The positioning engine server 120 obtains a personnel track trend according to the stored positioning information in the preset historical time period, if the personnel track trend is that the personnel moves outdoors, the personnel can be considered to leave the indoor area of the factory and enter the outdoor area of the factory, the positioning engine server 120 sends a control signal to the mobile terminal 110, and the outdoor positioning module 113 is started; if the person tracking trend is moving indoors, it may be considered that the person wants to leave the outdoor area of the factory and enter the indoor area of the factory, the positioning engine server 120 sends a control signal to the mobile terminal 110, turning off the outdoor positioning module 113.

TABLE 2
And after the Bluetooth positioning module scans the Bluetooth beacon positioned at the exit of the positioning scene, closing the outdoor positioning module under the condition that the next Bluetooth beacon is not scanned within a preset time period.
In this embodiment, the preset time period is a time period from when the preset outdoor positioning module scans the beacon signal to when the outdoor positioning module is turned off last time.
Specifically, the mobile terminal 110 packages the positioning information collected by the indoor positioning module 112 and the outdoor positioning module 113 into a positioning data packet, sends the positioning data packet to the positioning engine server 120, and the positioning engine server 120 analyzes the positioning data packet to obtain positioning information and stores the positioning information according to time. If the Major obtained by parsing the positioning data packet by the positioning engine server 120 characterizes a transition region of the installation location of the current beacon at the exit of the positioning scene, it may be considered that the person carrying the mobile terminal 110 is located at the transition region at the exit of the factory. The positioning engine server 120 obtains the occurrence time of the bluetooth beacon information according to the stored positioning information, starts timing from the occurrence of the bluetooth beacon information, and if no new bluetooth beacon information appears within a preset time period, the positioning engine server 120 can consider that a person leaves the factory area, sends a control signal to the mobile terminal 110, and closes the outdoor positioning module 113.
For example, assuming that the preset time period is 10 seconds, and the Major in the positioning information obtained by the positioning engine server 120 is 0x0040, the operator may be considered to be located in an off-site transition area or an on-site transition area, and after the positioning engine server 120 analyzes that beacon information is included in the obtained positioning information, if no beacon information is included in the positioning information obtained within 10 seconds, the operator may be considered to leave the factory area, and the outdoor positioning module 113 is turned off; if the beacon information exists in the positioning information obtained within 10 seconds, the personnel can be considered to be not leaving the factory area, and the outdoor positioning module 113 is not closed;
because the operating system of the mobile phone has an own running mechanism, the mechanism can actively close the programs cut into the background in order to release the memory and save power, especially the programs with more continuous power consumption in the background, so that the positioning process needs to perform keep-alive processing. Optionally, the mobile terminal further includes a service start module, where the service start module is configured to control the positioning process to be in an operating state.
In the present embodiment, the service initiation module is a virtual module in the mobile terminal 110.

According to the technical scheme, the positioning APP in the mobile terminal 110 can continuously run in the background by writing the positioning information acquisition, transmission and other programs into the service starting module, so that the positioning information of a user can be uploaded continuously in real time, the loss of positioning data packets is prevented, continuous track information can be formed on a positioning engine server, and the real-time positioning of personnel is achieved.
According to the technical scheme of the embodiment, whether a person is located in a transition area or not is determined by identifying the Bluetooth beacon signal, and the working state of the outdoor positioning module 113 is controlled according to the track trend of the person and/or the beacon signal, so that the working state of the outdoor positioning module 113 does not need to be manually switched, the indoor and outdoor positioning with high precision and high continuity can be realized, and the stability and accuracy of the positioning of the person are improved.
For example, in the case that the Major in the positioning information obtained by the positioning engine server 120 is 0x0080, the personnel can be considered to be located in the indoor transition area of the factory, if the personnel track trend is to move to the outside, the personnel can be considered to want to leave the indoor area of the factory and enter the outdoor area of the factory, and the outdoor positioning module 113 is started; if the person trajectory trend is moving indoors, it may be considered that the person does not want to leave the factory floor indoor area and enter the factory floor outdoor area, the outdoor positioning module 113 is not activated. In the case that the Major in the positioning information obtained by the positioning engine server 120 is 0x0100, the personnel can be considered to be located in the outdoor transition area of the factory, if the personnel track trend is to move to the outside, the personnel can be considered not to leave the outdoor area of the factory and enter the indoor area of the factory, and the outdoor positioning module 113 is not closed; if the person trajectory trend is moving indoors, it may be considered that the person wants to leave the factory floor outdoor area and enter the factory floor indoor area, the outdoor positioning module 113 is turned off.
