[0026] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0027] like Figure 1 As shown, a wireless automatic patrol system for a power pipeline corridor includes a path support 1, an explosion-proof walking device, an explosion-proof patrol collection device and a controller 6.

[0028] The path bracket 1 is two parallel rails, which are made of conductive and anti-corrosion material. In this embodiment, a DN15 galvanized steel pipe is selected. In this embodiment, the two parallel rails of the path bracket are arranged in parallel up and down, which can reduce the occupied plane space. The positive and negative poles of the 24V DC power supply are respectively connected on the two parallel rails; they are used to provide power for the walking motor and related equipment of this system.

[0029] The explosion-proof walking equipment includes a cabinet 3 and a walking wheel 2 connected to the cabinet. The walking wheel moves on two parallel tracks arranged up and down through a walking motor. The walking wheel is electrically connected to the track in a contact manner. The explosion-proof patrol collection equipment is arranged at a set position outside the cabinet for collecting data within the patrol range.

[0030] A controller 6 is provided in the cabinet, and the controller includes a signal input module, a control module, a data storage module, and a signal output module. The present application does not impose any restrictions on the model of the controller, and all usable controllers can be selected for use.

[0031] The explosion-proof patrol collection equipment is electrically connected to the signal input module and the data storage module, the data storage module is electrically connected to the control module, and the control module is electrically connected to the central control room through the signal output module.

[0032] In this application, the explosion-proof patrol data collection equipment includes one or more of a camera 5, a camera, a temperature sensor 4, and a gas sensor. All of the above equipment are explosion-proof equipment. For example, the camera can choose to take real-time video during the patrol process and transmit the real-time video to the control module, or it can choose to take video at a set location and then transmit the video to the control module. Each of the above equipment can upload the collected data to the central control room via wireless.

[0033] The present application also includes an alarm device, which is connected to the control module through a signal output module, and is respectively arranged in a cabinet or a central control room. The alarm device includes one or both of an alarm light or an alarm, and usually, the central control room is selected as the preferred alarm.

[0034] In the present application, a control method for a wireless automatic patrol system of a power pipeline corridor is also provided, comprising the following steps:

[0035] S1. Obtain photos within the patrol range and store them in the storage module of the controller and send them to the central control room. Specifically, a map within the patrol range is stored in the storage module and in the central control room, and the map is directly displayed on the display screen of the central control room. At the same time, the standard range values ​​of each parameter within the patrol range are stored in the storage module, and the standard range values ​​of each parameter here are determined according to actual needs.

[0036] S2. According to the first set interval time, in the present application, the first set time interval can be determined according to actual needs, such as 1 hour, 2 hours, 3 hours, 4 hours or other arbitrary set time. The explosion-proof walking equipment travels back and forth on the path bracket. At the same time, the explosion-proof patrol collection equipment transmits the collected real-time data of each parameter to the control module. The control module compares the real-time data of each parameter with the standard range of each parameter saved in the storage module. If the real-time data of each parameter are all within the set range, the patrol is completed. If any item is not within the set range, step S3 is entered.

[0037] S3, determine the parameter type and position that are not within the set range, mark the position on the map, and at the second set interval, the second set interval is less than the first set interval. By selecting 1 / 10-1 / 3 of the first set interval as the second set interval, the controller controls the explosion-proof walking device to move to the position for another patrol, and the corresponding explosion-proof patrol collection device collects the corresponding data and transmits it to the control module. Not all data collection devices are working here, of course, it is also possible to consider letting all data collection devices work, so as to monitor the position in detail from a comprehensive perspective. The control module first compares the standard range of the corresponding parameter saved by the storage module. If it is within the set range, it is considered to be a false monitoring, and the patrol is completed. If not, it enters step S4.

[0038] S4, the control module compares the corresponding data value of step S3 with the corresponding real-time data value of step S2. If the data value increases or remains unchanged, the controller sends an alarm signal to the alarm device and the central control room through the signal output module; if the data value decreases, step S3 is repeated at the second set interval time until the data value enters the standard range.

[0039] In the present application, in step S4, the control module compares the corresponding data of step S3 with the corresponding real-time data of step S2, which means comparing the data difference Δ1 obtained by the corresponding data value of step S3 minus the maximum value of the standard range with the data difference Δ2 obtained by the corresponding real-time data value of step S2 minus the maximum value of the standard range.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, but 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 invention.
