The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Referring to fig. 1, a method for positioning personnel in a power plant according to an embodiment of the present invention is applied to a power plant monitoring system, and the method includes:
step S10), acquiring a ZigBee signal sent from a mobile device, wherein the ZigBee signal comprises the sending time of the ZigBee signal and identification information of the mobile device, and the mobile device is worn by the power plant personnel;
step S20) acquiring the receiving time of each positioning device in at least three positioning devices installed at different positions of the power plant for receiving the ZigBee signal;
step S30) obtaining a current spatial position of the mobile device based on the fixed coordinates of each of the positioning devices, the transmission time of the ZigBee signal, and the reception time of the ZigBee signal;
step S40) based on the space position, a floor map corresponding to the space position is called, and the identification information and the space position corresponding to the identification information are displayed in the floor map in real time.
In the embodiment of the invention, networking is carried out in a special environment with high temperature, high pressure and high noise of a power plant through a wireless communication technology based on a ZigBee technology, and personnel in the power plant are positioned in real time through at least three positioning devices, so that the real-time three-dimensional position information of the personnel in the power plant is rapidly and accurately obtained, and the personnel in the power plant are displayed in a floor map corresponding to the current three-dimensional position information.
In this embodiment of the present invention, the acquiring of the ZigBee signal sent from the mobile device in step S10) includes: acquiring a ZigBee signal sent by the mobile equipment in a preset time period, wherein the preset time period is adjustable; and under the condition that the preset time period is adjusted, feeding back a ZigBee signal containing the adjusted time period to the mobile equipment.
Referring to fig. 2, in a possible embodiment, the floor of the power plant is divided into A, B, C, D four areas, the positioning devices are respectively and fixedly arranged at four corners of each area, and the number of the power plant personnel in each area is currently within a normal number range, for example, A, B, C, D has 5, 7, 9, and 8 power plant personnel in each area, so that the mobile device worn by the power plant personnel sends the ZigBee signal to the power plant monitoring system in a preset time period (for example, 200ms), after a period of time, 3 power plant personnel in 5 power plant personnel in the area a need to continue working in the area D, so that the power plant personnel are moved into the area D, so that there are only 2 power plant personnel in the area a after the movement, and there are 11 power plant personnel in the area D after the movement, at this time, the power plant monitoring system judges that there are few power plant personnel in the area a, therefore, the ZigBee signal sending period of the mobile equipment worn by the power plant personnel in the area A is adjusted to be 100ms, and a ZigBee signal containing the adjusted time period is sent to the mobile equipment worn by the 2 power plant personnel in the area A to control the corresponding mobile equipment to adjust the time period; based on the same principle, the power plant monitoring system judges that more power plant personnel exist in the D region, so that the ZigBee signal sending period of the mobile device worn by the power plant personnel in the D region is adjusted to 400ms, and a ZigBee signal containing the adjusted time period is sent to the mobile device worn by 11 power plant personnel in the D region to control the corresponding mobile device to adjust the time period.
When the number of power plant personnel in a working area is less, because no person supervises each other, the power plant personnel can more easily enter a dangerous area or cause an accident due to human negligence, meanwhile, when the number of people is less, mobile equipment for communicating with the positioning device is fewer, the duty ratio of the positioning device in a non-working state is larger, and resource waste exists to a certain extent, so that when the number of power plant personnel is less, the ZigBee signal sending time period of the mobile equipment is reduced, the real-time performance and the anti-interference performance of the ZigBee signal can be further improved, the phenomenon of ZigBee signal packet loss caused by larger environmental interference can be compensated, the utilization rate of the positioning device can be improved, and resources can be reasonably utilized; based on the same principle, when the number of power plant personnel in a working area is large, the ZigBee signal transmission period of the mobile device is increased, on the premise that the positioning accuracy is guaranteed, too many system resources are not occupied, the normal operation of communication is guaranteed, and the reliability of the power plant monitoring system is further improved.

Further, in the embodiment of the present invention, the different floor maps are set as a root (root) and a plurality of layers (Layer), where the root is a virtual node, for example, as the origin of coordinates (0,0,0) of the three-dimensional space, each Layer corresponds to the interval value of the Z coordinate, for example, the Z coordinate interval corresponding to the first Layer is 0-300, the Z coordinate interval corresponding to the second Layer is 301-600, and so on. Therefore, according to the fact that the Z-axis coordinate in the spatial position of the power plant personnel is 1300, the positioning floor where the mobile equipment is located is determined to be the 5 th floor, and at the moment, the floor map of the 5 th floor is called from the database.
Furthermore, in the embodiment of the present invention, each Layer (Layer) further includes a plurality of sublayers (ObjectLayer), each sublayer further includes a device module (Block), different layers can be very conveniently set when a map is maintained, the layers are displayed, hidden, moved or deleted, and the operated sublayers and device modules on each Layer can be uniformly processed.
In a complex environment of a power plant, different dangerous areas exist at different positions of different floors, so that personnel in the power plant need to be positioned more accurately to perform danger alarm, and through the implementation of the embodiment of the invention, the power plant monitoring system uniquely determines the spatial position of the current mobile equipment, which contains X-axis, Y-axis and Z-axis coordinates, through at least three positioning devices, so that the position of the power plant personnel at which floor the power plant personnel are located at can be accurately identified, and the accuracy of positioning the power plant personnel is further improved.
Meanwhile, hierarchical management is carried out on the floor data, when the position of a certain power plant personnel is required to be checked, only the current map of the power plant personnel is required to be called to be displayed in real time, and all map information is not required to be called, so that the calculation amount of the monitoring system is greatly optimized, the requirement of the monitoring system on hardware configuration is reduced, and the enterprise operation cost is reduced.
