[0002] Temporary grounding wires are a kind of safety short-circuit device that the power industry needs to connect during the power operation of the power distribution network transmission line. They are used as safety protection equipment to prevent sudden power outages from causing harm to operators. In the application of temporary grounding wires, it is easy to miss the grounding wire, miss the grounding wire, or hang the grounding wire with power on, which seriously threatens the personal safety of the staff and the safe and stable operation of the power grid.

[0003] At present, in the application process of grounding wires at power operation sites, most of them install some convenient monitoring devices on temporary grounding wires to realize automatic detection of the application status of temporary grounding wires.

[0055] In order to solve the technical problem of "blind adjustment" in distribution network dispatching caused by the inability of the dispatching master station to obtain accurate information of the remote operation process, including the hanging and removal of the ground wire, and at the same time solve the problem of large power consumption loss in the detection of the existing ground wire hanging status. In an embodiment of the present invention, a Beidou-based distribution network ground wire safety management and control system is deployed, which mainly includes a multi-dimensional operation information feedback system, a mobile intelligent terminal, and a Beidou positioning monitor installed on the ground wire, a status detection device and a warehouse charging adapter. Among them, the mobile intelligent terminal is communicatively connected to the multi-dimensional operation information feedback system, the Beidou positioning monitor is communicatively connected to the mobile intelligent terminal, and the status detection device is wirelessly connected to the Beidou positioning monitor. Among them, the Beidou positioning monitor and the status detection device are installed on a temporary ground wire.

[0056] Multi-dimensional operation information feedback system: installed on the server host, it realizes real-time communication with the on-site mobile intelligent terminal, task distribution, status display and data statistics, and supports interaction with third-party systems, mainly including:

[0057] (1) The system is connected to the GIS geographic information system to obtain the specific longitude and latitude location information of the tower;

[0058] (2) The system is connected to the high-precision location service platform of the Southern Power Grid to obtain the horizontal and elevation location information of the grounding wire and conduct real-time tracking and positioning management of the use of the grounding wire;

[0059] (3) The system is connected to the CSG elink office software and uses image analysis technology to analyze the images of the pole tower number and ground wire connection status taken by on-site personnel, that is, to double-confirm the ground wire connection status and position through image recognition.

[0060] (4) The system can push the ground wire status information to the SCADA system to grasp the ground wire status of the transmission line in real time and avoid the occurrence of ground wire closing accidents.

[0061] Mobile smart terminal: It has built-in applications, receives operation tickets on site through the 4G private network, and supports Bluetooth communication with the Beidou positioning monitor to achieve functions such as real-time transmission of status data and command issuance.

[0062] Beidou positioning monitor: It has built-in meter-level Beidou precise positioning, which enables the grounding wire location information and alarm information to be sent through the Southern Power Grid encryption module.

[0063] Status detection device: supports communication with the detection module at the hook-up end, realizes detection and feedback of the hook-up status of the grounding wire product, and sends the alarm information through the encryption module of the Southern Power Grid. Equipped with a rechargeable lithium battery, after returning to the warehouse (tool cabinet / room), wireless charging is automatically turned on, and the battery takes less than 10 hours to fully charge. When leaving the warehouse, it will automatically start working. There is no power button, which is simple to operate and can avoid shutdown caused by accidental human touch; the structure is light and convenient, with a "waterproof, dustproof, and drop-proof" design for harsh outdoor environments, and the protection level is not lower than IP65 requirements.

[0064] like Figure 1 As shown, the embodiment of the present invention discloses a method for detecting the status of a temporary grounding wire. The execution subject of the method may be a temporary grounding wire, or a status detection device arranged on the temporary grounding wire, and the present invention is not limited to this. The method comprises the following steps S10 to S70:

[0065] S10. According to the operation ticket, determine the destination location of the temporary grounding wire and its target air pressure value.

[0066] In an embodiment of the present invention, the multi-dimensional operation information feedback system includes a ground line anti-error system. The operation ticket can be generated by the ground line anti-error system according to the work task sent by the production management system. After generating the operation ticket, the ground line anti-error system sends it to the mobile intelligent terminal carried by the operator. After receiving the operation ticket, the mobile intelligent terminal sends the operation ticket to the Beidou positioning monitor. The Beidou positioning detector has a built-in controller. By identifying the operation ticket, the destination location of this operation can be determined.

[0067] Since the power equipment is distributed in areas with different altitudes, and the corresponding atmospheric pressures in areas with different altitudes are also different, the corresponding target air pressure values ​​are pre-measured and stored for the fixed positions of each power equipment. Once it is determined which power equipment this operation is for, the location of the power equipment can be retrieved as the destination location, and the pre-measured air pressure value corresponding to the destination location can be obtained as the target air pressure value.

[0068] S20. When it is detected that the temporary grounding wire leaves the warehouse, real-time location information of the temporary grounding wire is collected at a first preset frequency.

[0069] After the operator takes out the temporary grounding wire from the warehouse, the temporary grounding wire needs to be carried to the destination. When the temporary grounding wire is placed in the warehouse, the status detection device set on the temporary grounding wire can detect the wireless signal detected by itself in real time. When the wireless signal is less than the preset strength, it is determined that it has been taken out of the warehouse, that is, it is determined that the temporary grounding wire has left the warehouse. On the way from the warehouse to the on-site destination, the status detection device can send a positioning instruction to the Beidou positioning monitor, so that the Beidou positioning monitor collects and obtains real-time positioning information at a first preset frequency, and the real-time position information of the temporary grounding wire can be determined based on the positioning information.

[0070] S30, determine whether the distance between the real-time location information and the destination location is less than a specified threshold. If so, execute step S40; otherwise, end this process.

[0071] By calculating the geographical distance between the two locations, the distance between the temporary grounding line and the destination location can be obtained. When the distance is small, the collection of real-time air pressure values ​​is started.

[0072] S40: If the interval distance is less than a specified threshold, collect the real-time air pressure value of the temporary grounding wire at a second preset frequency, wherein the second preset frequency is greater than the first preset frequency.

[0073] By setting the frequency of collecting real-time air pressure values ​​to be greater than the frequency of collecting real-time position information, the accuracy of detection can be improved.

[0074] S50: If the real-time air pressure value matches the target air pressure value, it is determined that the temporary grounding wire has reached the destination position.

[0075] Among them, when the difference between the real-time air pressure value and the target air pressure value is less than the allowable error, the real-time air pressure value can be regarded as matching the target air pressure value. The allowable error can be a specified value set in advance. That is, it is not necessary to determine that the temporary grounding wire has reached the destination position only when the measured real-time air pressure value is exactly the same as the target air pressure value. A certain degree of floating can be allowed. As long as the difference between the measured real-time air pressure value and the target air pressure value is small and less than the allowable error, it can be determined that the temporary grounding wire has reached the destination position.

[0076] After determining that the temporary grounding wire has reached the destination position, the real-time position information and real-time air pressure value detected at the latest moment can also be sent to the mobile intelligent terminal. The mobile intelligent terminal further determines whether the current state of the wire end is opposite to the target state of this operation. For example, if this operation is to hang the temporary grounding wire, the target state is hanging, then determine whether the current state of the wire end is not hung; conversely, if this operation is to remove the temporary grounding wire, the target state is removal, then determine whether the current state of the wire end is hung.

[0077] Therefore, step S60 may be executed only when it is determined that the temporary grounding wire has reached the destination position and the mobile intelligent terminal determines whether the current state of the wire end is opposite to the target state of this operation.

[0078] S60: Start monitoring to obtain a first connection state of the temporary grounding wire.

[0079] As an optional implementation, step S60 may include: obtaining a voltage value detected by a voltage detector, determining a loop resistance based on the voltage value and a DC power supply current value, determining a contact resistance based on a difference between the loop resistance and the metal resistance, and determining a first hanging state of the temporary grounding wire based on the contact resistance.

[0080] Among them, determining the first hanging state of the temporary grounding wire according to the contact resistance value can specifically include: judging whether the contact resistance value is within a preset range, if it is within the preset range, determining that the first hanging state of the temporary grounding wire is normal hanging, otherwise, determining that the first hanging state of the temporary grounding wire is abnormal hanging.

[0081] S70. Determine a target hanging state of the temporary grounding wire according to the first hanging state.

[0082] In some embodiments, the first hooking state may be directly used as the target hooking state of the temporary grounding line in step S70; or in some other embodiments, step S70 may also include the following steps S701 to S703:

[0083] S701. Determine a second mounting state according to picture information of the scene taken by an operator.

[0084] After the operator (such as a person who goes to the site to repair the power equipment) hangs the temporary grounding wire to the wire end, he can use a handheld mobile smart terminal to take a picture of the site. Based on the picture, the picture information can be extracted, and the second hanging state based on machine vision can be identified based on the picture information. It is convenient to merge the judgment with the first hanging state detected by the state detection device, realize double confirmation, and improve the judgment accuracy.

[0085] S702: Calculate the similarity between the first mounting state and the second mounting state.

[0086] In information coding, the number of bits that are encoded differently in the corresponding bits of two legal codes is called the code distance, also known as the Hamming distance. In a valid code set, the minimum value of the Hamming distance between any two code words is called the Hamming distance of the code set. For example, 10101 and 00110 are different in the first, fourth, and fifth bits starting from the first bit, so the Hamming distance is 3.

[0087] Preferably, in step S702, the first mounting state and the second mounting state can be mapped to binary to obtain respective hash codes, and then the Hamming distance between the first hash code corresponding to the first mounting state and the second hash code corresponding to the second mounting state is calculated, and the similarity between the two is determined according to the Hamming distance.

[0088] The smaller the Hamming distance, the more similar the two are, and the larger the Hamming distance, the greater the difference between the two. For example, the reciprocal of the Hamming distance can be used as the similarity between the two. For example, the reciprocal of the Hamming distance can be used as the similarity between the two. By calculating the hash code to obtain the similarity, more detailed information can be retained and the calculation accuracy can be improved.

[0089] S703: If the similarity reaches a preset similarity, determine a target hanging state of the temporary grounding wire according to the first hanging state and the second hanging state.

[0090] If the similarity reaches a preset similarity, any one of the first hanging state and the second hanging state can be determined as the target hanging state of the temporary grounding line. The preset similarity can be a preset specific value such as 70%, 80%, 93%, etc.

[0091] It can be seen that, by implementing the embodiment of the present invention, the destination position of the temporary grounding wire and its target air pressure value are determined according to the operation ticket, and then when the temporary grounding wire is monitored to leave the warehouse, the real-time position information of the temporary grounding wire is collected at a lower frequency. When the interval distance between the real-time position information and the destination position is less than the specified threshold, the real-time air pressure value of the temporary grounding wire is obtained at a higher frequency and compared with the target air pressure value. If they match, it is determined that the temporary grounding wire has reached the destination position, and the monitoring of the hanging status of the temporary grounding wire is started. Therefore, the hanging status collection of the temporary grounding wire can be started only when the grounding wire reaches the destination, thereby reducing the power consumption of detecting the hanging status of the grounding wire.

[0092] At the same time, it can also check whether the grounding wire positioning data is consistent with the on-site operation destination to prevent safety accidents caused by personnel installing the grounding wire in the wrong position. The working process covers all real-time action status and location information monitoring of the distribution network grounding wire. In terms of usage, it is seamlessly integrated with the conventional operation mode, without changing the operation process, and realizes real-time monitoring of the grounding wire throughout the process in a servo manner.
