Problems solved by technology

[0005] 1. Power carrier communication is more suitable for power carrier communication in the case of shorter distance and lower transmission line voltage. When the inspection distance increases or there is strong electrical signal interference on the transmission line, the reliability of this method will be greatly improved. reduce
[0006] 2. The mobile communication network needs to rely on the base station network of the mobile service operator. This method is difficult to meet better communication requirements in areas with few base stations, and the cost of use is high, and the communication information needs to pass through the third-party operator server , there are unsafe factors
[0007] 3. Wireless communication links, such as the signal relay communication method disclosed in Chinese patent CN201510758209.9, realizes communication by establishing communication channels distributed along power transmission lines, but this communication method is transmitted along fixed communication routes, and power transmission lines It is not distributed along a straight line, which causes redundant transmission of communication signals at cable bends, reduces communication efficiency, and takes a long time when the amount of data is large
[0008] The current inspection method is that each team carries inspection vehicles and wireless communication equipment to conduct inspections on the transmission cable. The inspection equipment carried by these teams, such as thermal imagers, needs to transmit the collected data to the inspection and control department in a timely manner. The background station, and the existing communication methods are not suitable for transmission operations due to poor signal quality, high cost, and large data volume. If these wireless resources can be integrated together, it will greatly facilitate the effect of inspection communication and improve communication efficiency

specific Embodiment 1

[0040] Specific embodiment 1, in order to solve the problem that the existing tower-based communication system transmits information step by step, but cannot perform the function of inspection vehicles and other units equipped with communication equipment, the construction method of the inspection communication includes the following steps such as figure 1 shown, including the following steps,

[0041] a. The position coordinates of all transmission base stations are updated to the background terminal station in real time through the satellite communication module. These data also facilitate the control of inspection personnel and vehicles;

[0042] b. The inspectors initiate a communication request to the background terminal through the satellite communication module of the transmission base station;

[0043] c. After summarizing the position coordinates of all the transmission base stations in the background general station, it calculates all the transmission base stations ...

specific Embodiment 2

[0049] Specific embodiment 2, such as Figure 2 to Figure 5 As shown, in the step c, the calculation method of the communication link of the background station is:

[0050] c1. Mark the position coordinates of all the transmission base stations on the map, mark the position coordinates of the transmission base stations that initiate the communication request as the starting point, and mark the position coordinates of the background total station as the end point;

[0051]c2. Draw a ray from the starting point to the end point, and take the starting point as the origin, and the ray from the starting point to the end point is the positive direction of the X-axis, and establish a rectangular coordinate system;

[0052] c3. Taking the starting point as the center of the circle and taking the maximum broadcast distance r of the transmission base station as the radius to draw a broadcast circle, all transmission base stations falling into the broadcast circle in the first and fourth...

specific Embodiment 3

[0066] Specific embodiment 3, in the step e, the connection method of the communication link is that the transmission base station performs a handshake connection with the adjacent next-level transmission base station, and the transmission base station wirelessly sends a request signal to the next-level transmission base station, and receives It is determined that the transmission base station is connected after the feedback signal sent back by the adjacent next-level transmission base station. The above connection method starts from the No. 1 inspection vehicle-mounted base station, and verifies the connection status step by step. If the connection is not smooth, as in the step f mentioned above, if there is no normal feedback in the communication link within the time delay T For the transmission base station, the background station will remove the position coordinates of the transmission base stations that have not been fed back normally, and return to step c. At this time, ...

Description

technical field [0001] The invention belongs to the field of high-voltage cable inspection communication methods, and in particular relates to an inspection communication method for a high-voltage cable inspection vehicle. Background technique [0002] With the improvement of modern management concepts, on-site operation and maintenance management must gradually change from extensive to refined management, and from information to digital and intelligent operation and maintenance support. [0003] However, the intelligent operation and maintenance of cable inspection is very difficult to realize. The current operating environment of cable inspection is complex, especially the high-voltage cables are widely distributed in county areas, which is not conducive to centralized and lean management. The problem of inconvenient communication in the area can easily lead to the lack of inspection information, which is not conducive to the transformation of on-site operation and mainten...
