[0031] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0032] Figure 1 is a system architecture diagram of a water and electricity project construction site inspection system based on Beidou satellite positioning. As shown in Figure 1 , the system architecture is divided into a server and a patrol terminal, the number of patrol terminals can be a positive integer N, N is generally not more than 20, the patrol terminal and the server are connected through a wireless network. The system can adopt C / S or B / S architecture, and the present application does not make specific limitation on this.

[0033] Figure 2 is a function framework diagram of a water and electricity project construction site inspection system based on Beidou satellite positioning. As shown in Figure 2 , the water and electricity project construction site inspection system based on Beidou satellite positioning provided by the present application mainly includes a patrol task setting module, a data acquisition module, an emergency rescue module and a patrol information display module.

[0034] The user of the inspection task setting module is an administrator, who is responsible for configuring the information and parameters related to the inspection task, such as the time information of initiating the inspection, the personnel information of performing the inspection, the information of checking which inspection items of which inspection points and the standard setting of the inspection, the order of the inspection points, and the like, which is a relatively tedious work. Figure 3 As shown in FIG. 8, the inspection task setting module of the present application includes an inspection line setting unit, an inspection time setting unit, an inspector setting unit, a checkpoint setting unit, and an inspection type setting unit.

[0035] The inspection line setting unit in the inspection task setting module of the present application provides a plurality of automatic generation methods of the inspection line, and simplifies and optimizes the tedious operation of setting the inspection line. The inspection line setting unit includes a function of planning the inspection line based on the GIS map, and also includes a function of automatically generating the inspection line based on the order of the inspection points.

[0036] The function of planning the inspection line based on the GIS map includes that the administrator first manually filters out the inspection points, sets the starting point and the ending point of the inspection line based on the GIS map, and automatically generates the inspection line according to the principle of the shortest total inspection line. For example, the administrator first filters out 7 inspection points to be inspected, sets the inspection point to be inspected first and the inspection point to be inspected last, and the system automatically plans the inspection line.

[0037] The function of planning the inspection line based on the GIS map also includes that the administrator clicks the inspection points based on the GIS map, and automatically generates the inspection line according to the order of clicking. Clicking the inspection points based on the GIS map is essentially equivalent to the process of the administrator manually filtering out the inspection points. The system automatically records the order of clicking each inspection point by the administrator, and automatically plans the inspection line according to the order of clicking.

[0038] The function of planning the inspection line based on the GIS map also includes that the administrator frames the inspection area by the mouse based on the GIS map. If multiple inspection areas are framed, the inspection line is generated between the multiple inspection areas according to the order of framing. If the framed area contains a plurality of inspection points, the inspection line between the inspection points in the area is generated according to the principle of the shortest total inspection line.

[0039] The function of automatically generating the inspection line based on the order of the inspection points includes that the inspection points are filtered out, the inspection sequence numbers are set for the inspection points, and the inspection path is automatically generated in ascending order of the inspection sequence numbers. For example, the administrator selects 10 inspection points, sets an inspection sequence number, which is preferably a positive integer, for each inspection point, and then the system generates the inspection line in ascending order of the inspection sequence numbers.

[0040] The inspection time setting unit includes setting the inspection start time and the inspection end time, and the inspector should complete the inspection work within the set inspection start and end time. The checkpoint setting unit is mainly used for setting the geographic position of the inspection point, for example, the specific position and coordinates located at the construction site; setting the inspection point responsible person information, including the contact number, name, position and other information of the responsible person. Setting each inspection item of the inspection point and the corresponding inspection standard, inspection specification and other information. The inspector setting unit is used for setting the personnel performing the inspection task, so that the personnel can automatically download the corresponding inspection task when logging in the inspection terminal. The inspection types include routine inspection, special inspection and holiday inspection. Each type of inspection contains different inspection points, for example, the holiday inspection generally contains more comprehensive inspection points, and the special inspection can be set according to needs, for example, hoisting equipment special inspection, fire hazard investigation special inspection and the like.

[0041] The data acquisition module mainly includes an inspection terminal, which includes but is not limited to a smart phone, a tablet computer, a PDA and the like. As shown in Figure 4 The inspection terminal mainly includes a positioning module, an image shooting and identification module, a task downloading module and a data uploading module. The positioning module is used for collecting the coordinates of the inspector in real time, obtaining the activity track and uploading. The positioning module adopts the Beidou satellite positioning technology, and has higher positioning accuracy. The image shooting and identification module obtains the equipment operation parameter information through the image recognition function based on the shot picture. The task downloading module is used for downloading the inspection task. After the inspector uses the inspection terminal to connect to the service end, the inspection task assigned to the inspector is automatically downloaded. The data uploading module is used for uploading the pictures shot and the data recorded in the inspection process. After the data is uploaded, it is used for data analysis and decision-making.

[0042] In the construction site inspection process, various instrument and meter data reading and identification of the device status indicator light are encountered. The present application can quickly read the instrument and meter data and the device state through the image recognition function. The image recognition function of the present application includes an instrument value identification function and a device state identification function. The instrument value identification function includes an OCR identification function and a pointer identification function, which are used to identify the instrument name, identify the pointer position and automatically obtain the instrument value. First, the target detection algorithm is used to detect the position of the pointer in the picture. After determining the position of the pointer, the OCR technology is used to read the value pointed to. The state identification function uses mature color recognition algorithm to identify the corresponding state of the device according to the color of the state indicator light. Under normal circumstances, the indicator light is yellow, indicating that the device is faulty, and the indicator light is green, indicating that the device is running normally. The target detection algorithm can adopt traditional target detection algorithms such as YOLO, SSD and CNN. For this, the present application does not make specific limitation.

[0043] The emergency rescue module mainly comprises a fault analysis unit. The fault analysis unit analyzes based on historical operation data of the equipment to predict the equipment fault. Data values of key indicators of the equipment in a period of time before the equipment fault occurs are obtained. One week of data or half a month of data can be selected according to the situation. The selection of the time period is not limited in the application. After the data values are obtained, a curve graph is drawn. Then, one week of data or half a month of data of the current equipment is obtained to draw a curve. If the trend is consistent, the probability of the equipment fault is determined according to the ratio of the number of overlapping values in the curve to the total number. The fault analysis unit can find the trend fault, timely maintenance and repair, and reduce the number of equipment faults.

[0044] The emergency rescue module further comprises a fault alarm unit. The fault alarm unit is used for alarming the fault information reported by the inspection personnel and the fault information predicted by the fault analysis unit. The alarm mode comprises sending a message to the person in charge of the inspection point and displaying the inspection point with a fault in a flashing manner in the inspection information display module.

[0045] The inspection information display module is mainly used for displaying real-time position information, inspection line information and inspection result information of the inspection personnel. The inspection information display module displays the inspection line in different colors. Preferably, the completed inspection line is marked with gray, and the uncompleted inspection line is marked with green. Preferably, when the real-time positioning information of the inspection personnel deviates from the inspection line, the inspection terminal is sent with an inspection line deviation prompt information. Preferably, when the actual inspection time exceeds the set time of the inspection task, the inspection terminal is sent with an inspection timeout prompt information.

[0046] Preferably, when the position of the inspection personnel deviates from the inspection line for more than a set threshold, or the inspection time is exceeded, the real-time position information and the inspection line information of the inspection personnel are displayed in a flashing manner. The real-time position of the inspection personnel can be represented by a shape such as a dot, or a head portrait or a portrait.

[0047] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
