In the event of an emergency, industrial personnel need to evacuate to the industrial zone for evacuation, and cannot be based on industrial zone personnel. The current position, generating a high-accuracy evacuation route between the current location and the evacuation point of the industrial zone, is not conducive to and evacuation.

[0004] For example, an industrial zone personnel is a nuclear power industrial zone personnel, and an industrial zone evacuation point is an evacuation point of a nuclear power industrial zone. When an emergency occurs, a nuclear power industrial zone personnel needs to reach an industrial zone evacuation point, and cannot obtain an industrial zone evacuation. Point high precision evacuation lines. The reason is that the existing industrial zone management system generally adopts the following three positioning methods, which are detailed as follows:

[0005] The first positioning method adopts GPS positioning mode. Since GPS positioning is global positioning, it will be affected by various factors, and the positioning accuracy is low. Therefore, the industrial location management system of the industrial area using GPS positioning mode is adopted. It is impossible to locate high-precision personnel in industrial areas in industrial areas;

[0006] The second positioning method is to image recognition of the location of the industrial area personnel. Since the image is susceptible to light and dark interference, the image data is limited by the camera coverage of the industrial area, so it is often difficult to identify the image in the background. Industrial area personnel, so it is impossible to locate high-precision personnel in industrial areas in industrial areas

[0007] The third positioning method, the narrowband wireless communication positioning method represented by RFID and ZIGbee, because the narrowband wireless communication itself is limited by the frequency band, it is impossible to accurately position the industrial area personnel in the industrial area, and in addition, the narrow band The signal is susceptible to weather or other signals, and thus easily affects the stability of the location management system of industrial personnel. technical problem

[0008] An object of the embodiments of the present invention is to provide an industrial area evacuation system, which aims to solve the existing industrial area management system, and cannot perform high-precision positioning and insufficient positioning stability for industrial area personnel, when an emergency occurs, industrial The personnel of the district need to evacuate to the evacuation point of the industrial area, and it is impossible to generate a high-accuracy evacuation route between the current location and the evacuation point of the industrial zone according to the current location of the industrial zone personnel.

Problem solution

Technical solution

[0009] The embodiment of the present invention is implemented in this way, an industrial area evacuation system, including:

[0010] in an industrial area personnel, an evacuation wear device that transmits an ultra-wideband pulse signal;

[0011] interconnecting and synchronizing at least three base stations for receiving the ultra-wideband pulse signal, uploading and receiving the engraving of the ultra-wideband pulse signal;

[0012] an industrial area evacuation device connected to the base station, configured to locate the evacuation wearable device according to a preset positioning algorithm and an engraving of the super-wideband pulse signal uploaded by each of the base stations, according to pre-storage The industrial area coordinate database locates the industrial area where the evacuation wearable device is located, and when the industrial area is an industrial area to be evacuated, the evacuation line of the evacuation wearable device to the evacuation point of the industrial area is drawn.

Another object of an embodiment of the present invention is to provide an evacuation method based on the industrial zone evacuation system described above, including:

[0014] the evacuation wear device transmits an ultra-wideband pulse signal to the base station;

[0015] the base station receives the ultra-wideband pulse signal, uploading and receiving the ultra-wideband pulse signal to the industrial area evacuation device;

[0016] the industrial area evacuation device locates the evacuation wearable device according to a preset positioning algorithm and an engraving of the super-wideband pulse signal uploaded by each of the base stations, and locates according to a pre-stored industrial zone coordinate database. The industrial area where the evacuation wearable device is located, when the industrial area is an industrial area to be evacuated, the evacuation line of the evacuation wearable device to the evacuation point of the industrial area is drawn.

Advantageous effects of the invention

Beneficial effect

[0017] In the embodiment of the present invention, an industrial area evacuation system is provided, and the evacuation wearable device is located according to a preset positioning algorithm and an engraving of the super-wideband pulse signal uploaded by each of the base stations, according to The pre-stored industrial area coordinate database locates the industrial area where the evacuation wearable device is located, and when the industrial area is the industrial area to be evacuated, draws the evacuation line of the evacuation wearable device to the evacuation point of the industrial area. The existing industrial zone management system has been solved, and it is impossible to carry out high-precision positioning and insufficient positioning stability for industrial zone personnel. In the event of an emergency, the industrial zone personnel need to evacuate to the industrial zone evacuation point, and cannot be based on the current location of the industrial zone personnel. , to generate a problem of high-accuracy evacuation lines between the current location and the industrial area evacuation point. The beneficial effects are in two aspects, as detailed below:

[0018] On the one hand, the signal transmission between the base station and the base station uses ultra-wideband wireless communication technology between the base station and the evacuation wearable device, and the ultra-wideband wireless communication technology uses the nanosecond non-sinusoidal narrow pulse transmission data. With high frequency bandwidth, multi-channel, low power consumption, low interference, high safety factor, coexistence with existing spectrum, and no interference with existing communication applications, high-precision positioning can be achieved by moving evacuated wearable devices. In addition, the high-precision positioning of the industrial personnel who evacuate the wearable device can also enhance the stability of the positioning.

[0019] On the other hand, according to the coordinates of the evacuation wearable device and the pre-stored industrial zone coordinate database, the location of the industrial zone personnel is located, and since the coordinate precision of the evacuation wearable device is high and the transmission delay is low, the error can be avoided. Reporting the location of personnel in the industrial zone reduces the false positive rate of the location of personnel in the industrial zone. At the same time, the evacuation wearable device can be used in the industrial area personnel to generate an evacuation route for evacuating the wearable device to the evacuation point of the industrial area according to the current position of the evacuation wearable device without the off-the-shelf device falling off. The evacuation line is the evacuation route from the industrial area personnel to the evacuation point of the industrial area. Due to the high coordinate accuracy of the evacuation wearing device, a highly accurate evacuation line can be generated. By displaying the evacuation line, the industrial area personnel can be quickly reached to the evacuation point of the industrial area, which greatly improves the evacuation efficiency of the industrial area, and is beneficial to improving the rescue efficiency of the industrial area personnel and ensuring the safety of the industrial area.
