Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent operation and maintenance of power systems, and specifically is an intelligent operation method based on ultra-high voltage intelligent inspection. Background Art

[0002] The traditional "one-button sequential control video double confirmation" method involves the patrol host transmitting the results of knife switch and switch video recognition to the specified path of the reverse isolation device through the CIM / E language format. The auxiliary equipment monitoring system obtains the reverse isolation device video recognition results through regular patrols and then transmits them back to the one-button sequential control host through the firewall. The reverse data flow needs to pass through four devices to reach the one-button sequential control host. The data flow is too long, and data acquisition also obtains video recognition results through regular patrols, resulting in non-real-time data acquisition, certain lags, and instability. Therefore, the present invention provides an intelligent opening method based on ultra-high voltage intelligent patrols. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned solutions, the present invention provides an intelligent opening method based on ultra-high voltage intelligent patrol.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0007] Step 2: Connect the intelligent output module to the corresponding inspection system host through the multi-point RS-485 network;

[0008] The patrol system host generates corresponding control signals for remote control and transmits them through the RS-485 network. The intelligent opening module verifies the received control signals. If the verification fails, no operation is performed. If the verification succeeds, the corresponding hard contact is opened according to the received control information, and the opening status of the corresponding hard contact is obtained, and the obtained hard contact opening status is returned to the patrol system host.

[0009] Step 3: Output the open contact corresponding to the control signal.

[0010] Furthermore, the hard contact output signal of the intelligent output module is generated by driving the relay through the control signal.

[0011] Furthermore, the intelligent output module is packaged in a rugged industrial-grade plastic chassis and provides intelligent signal conditioning, analog I / O, digital I / O, RS-232 and RS-485 communications.

[0012] Furthermore, the I / O board of the intelligent output module supports 10-30DC voltage and relay output.

[0013] Furthermore, when the control signal generated by the patrol system host is an anti-interference control signal, the method for verifying the received control signal includes:

[0015] Identify the received control signal, obtain the corresponding hard contact, match the corresponding calibration information from the calibration matching table according to the identified hard contact, compare the matched calibration information with the corresponding control signal, and obtain the corresponding calibration result, including calibration success and calibration failure; when the control signal is not successfully identified, the signal recognition model processes the control signal, obtains the corresponding signal anti-interference segment, matches the corresponding identification verification information, and performs calibration based on the obtained signal anti-interference segment and the identification verification information to obtain the calibration result. When the calibration result is calibration success, match the corresponding hard contact through the identification verification information.

[0016] Furthermore, the method for the patrol system host to generate an anti-interference control signal includes:

[0017] Acquire the control signal transmission environment, set the influencing positioning coordinates according to the acquired control signal transmission environment, match the corresponding signal anti-interference segment according to the set influencing positioning coordinates, integrate the acquired signal anti-interference segment with the corresponding control signal to be generated, and obtain the corresponding control signal.

[0018] Furthermore, the method of setting the influencing positioning coordinates according to the acquired control signal transmission environment includes:

[0019] Identify the transmission environment data of the control signal, divide the transmission environment data into sub-items, obtain sub-item data, assign values ​​to the sub-item data, obtain sub-item representative values, integrate the sub-item representative values, and obtain the impact positioning coordinates.

[0020] Furthermore, the method of dividing the transmission environment data into sub-items includes:

[0021] Set the sub-item types and corresponding sub-item keywords of the transmission environment data, integrate and establish a sub-item identification table, and divide the transmission environment data into sub-items according to the established sub-item identification table.

[0024] Furthermore, the method for establishing a positioning matching graph includes:

[0026] Compared with existing technologies, the present invention has the following advantages: it utilizes the high-reliability, low-latency, and low-cost hard-contact relay output principle to output received control information via hard-contact output. The input device on the opposite side then receives the position change signal, enabling the main equipment monitoring system to perform one-touch sequential control logic judgment. This solves the pain points and difficulties of data transmission in traditional forward and reverse isolation devices and greatly simplifies the information exchange process.

[0031] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 3 As shown, an intelligent opening method based on ultra-high voltage intelligent inspection is provided, and the specific method includes:

[0033] Step 1: Setting up an intelligent output module, which is used to collect data and perform corresponding control according to the control signal; the intelligent output module controls, monitors and collects data through a multi-channel I / O module;

[0034] The intelligent output module is encapsulated in a rugged industrial-grade plastic base and provides intelligent signal conditioning, analog I / O, digital I / O, RS-232 and RS-485 communications; it can handle up to 8 I / O module combinations (128 I / O points).

[0035] The I / O board of the intelligent output module supports 10-30DC voltage and relay output.

[0036] The analog modules offer 16-bit resolution and programmable input and output signal ranges.

[0037] Step 2: Connect the intelligent output module to the corresponding inspection system host through the multi-point RS-485 network;

[0038] The patrol system host generates corresponding control signals for remote control and transmits them through the RS-485 network. The intelligent opening module verifies the received control signals to ensure that the output hard contacts correspond to the received control signals. When the verification fails, no operation is performed. When the verification succeeds, the corresponding hard contacts are opened according to the received control information, and the opening status of the corresponding hard contacts is obtained, and the obtained opening status of the hard contacts is returned to the patrol system host.

[0039] The hard contact opening signal of the intelligent opening module is mainly generated by driving the relay through the control signal. After receiving the control signal, it can autonomously identify the corresponding relay and open the corresponding hard contact;

[0040] The intelligent opening module establishes physical and communication connections with the patrol system host through 232 / 485 wiring to receive control information.

[0041] In one embodiment, when the control signal generated by the patrol system host is a common control signal, the method for verifying the received control signal includes:

[0042] Acquire the hard contact information, set the corresponding calibration information according to the acquired hard contact information, the calibration information is set according to the control signal generated by the corresponding patrol system host, that is, the calibration information set for each hard contact corresponds to the control signal generated by the corresponding patrol system host, and the corresponding control signal is calibrated by comparing the calibration information with the corresponding control signal, set the corresponding calibration matching table according to the set calibration information, obtain the received control signal, identify the hard contact corresponding to the control signal, that is, which hard contact is to be controlled, match the corresponding calibration information from the calibration matching table according to the identified hard contact, compare the matched calibration information and the corresponding control signal, and obtain the corresponding calibration result. The specific undisclosed part is common knowledge in this field.

[0043] In another embodiment, when the control signal generated by the patrol system host is a commonly used control signal, the method for verifying the received control signal is to directly use an existing verification method for verification.

[0044] In one embodiment, when the control signal generated by the patrol system host is an anti-interference control signal, the method for verifying the received control signal includes:

[0045] Acquire the existing signal anti-interference segment, set corresponding identification verification information and a signal recognition model based on the existing signal anti-interference segment, and associate the corresponding hard connection point with the identification verification information. The signal recognition model is used to extract the signal anti-interference segment of the control signal when the signal is received. Specifically, it is set by an expert group and can adopt a learning model. Acquire the existing hard connection point information, set corresponding verification information based on the obtained hard connection point information, and set a corresponding verification matching table based on the set verification information.

[0046] Identify the received control signal, obtain the corresponding hard contact, match the corresponding calibration information from the calibration matching table based on the identified hard contact, compare the matched calibration information with the corresponding control signal, and obtain a corresponding calibration result, including calibration success and calibration failure. If the control signal is not successfully identified, the signal recognition model processes the control signal to obtain a corresponding signal anti-interference segment, match the corresponding identification verification information, and perform a calibration based on the obtained signal anti-interference segment and the identification verification information to obtain a calibration result. If the calibration result is successful, match the corresponding hard contact based on the identification verification information. Specific undisclosed portions are common knowledge in the art and are therefore not described in detail.

[0047] The method for the patrol system host to generate an anti-interference control signal includes:

[0048] Obtain the control signal transmission environment, such as the surrounding voltage environment, current environment, magnetic field environment, etc. Because it is carried out under ultra-high voltage intelligent patrol conditions, the transmission environment is relatively harsh, which can easily affect the transmission of the control signal, causing control signal distortion and affecting the operation of the corresponding system. Therefore, corresponding anti-interference settings are required; according to the obtained control signal transmission environment, the affected positioning coordinates are set, and the corresponding signal anti-interference segment is matched according to the set affected positioning coordinates. The obtained signal anti-interference segment is integrated with the corresponding control signal to be generated to obtain the corresponding control signal.

[0049] The obtained signal anti-interference segment is integrated with the corresponding control signal to be generated. The integration can be directly carried out using existing technology, or an expert group can set a corresponding integration method based on the control signal to be generated and the signal anti-interference segment, and the integration is carried out according to the set integration method; specifically, it is common knowledge in this field.

[0050] The method of setting the positioning coordinates according to the acquired control signal transmission environment includes:

[0051] Identify the transmission environment data of the control signal, divide the transmission environment data into sub-items, obtain sub-item data, assign values ​​to the sub-item data, obtain sub-item representative values, integrate the sub-item representative values, and obtain the impact positioning coordinates.

[0052] Methods for segmenting transmission environment data include:

[0053] Manually set the transmission environment data's item categories and corresponding item keywords, integrate and establish an item identification table, and then segment the transmission environment data into items based on the established item identification table. The item identification table identifies the corresponding item keywords in the transmission environment data, and then segment the data based on the identified item keywords. The undisclosed portions of this information can all be implemented using existing methods.

[0054] The method for assigning sub-item data includes: obtaining the types of sub-item data, setting a corresponding assignment method for each type of sub-item data. For example, for sub-item data that are numerical values, the corresponding numerical values ​​can be directly extracted as representative values. For sub-item data that are not numerical values, a corresponding matching table can be set to obtain the corresponding representative value after matching. The expert group can also set the corresponding assignment conditions, and assign values ​​based on the set assignment conditions through the existing assignment method to obtain the corresponding representative value. The specific undisclosed parts are common knowledge in this field, so they are not described in detail.

[0055] The method of matching the corresponding signal anti-interference segment according to the set impact positioning coordinates includes:

[0056] Establish a positioning matching map, associate the corresponding signal anti-interference segment storage library according to the established positioning matching map, obtain the affected positioning coordinates, input the obtained affected positioning coordinates into the positioning matching map, identify the coordinate area where the affected positioning coordinates are located, and match the corresponding signal anti-interference segment.

[0057] In one embodiment, the signal anti-interference segment is a signal segment with anti-interference function that is set by an expert group and represents the corresponding control signal. That is, when the corresponding control signal cannot be identified due to interference, the signal anti-interference segment is extracted and the corresponding control meaning is matched by identifying the signal anti-interference segment.

[0058] In another embodiment, the signal anti-interference segment is set by an expert group to assist the control signal in anti-interference and is set based on existing communication technology.

[0059] Methods for establishing a positioning matching graph include:

[0060] Conduct transmission environment data simulation, establish several simulation coordinates, input the simulation coordinates into the original coordinate system, and the expert group sets the coordinate transformation set according to the setting process of the signal anti-interference segment. Adjust the original coordinate system through the set coordinate transformation set to obtain the transformed coordinate system, identify the coordinates of the simulation coordinates relative to the transformed coordinate system, mark them as transformed coordinates, cluster based on the transformed coordinates, obtain several clusters, mark the coordinate areas corresponding to the clusters, and add corresponding area labels; convert them into corresponding positioning matching maps.

[0061] Because directly using the simulated coordinates and the original coordinate system for subsequent data analysis will result in large errors, the errors can be greatly eliminated after conversion through the coordinate transformation set set by the expert group. Adjusting the coordinate system through the coordinate transformation set is equivalent to building another coordinate system within the original coordinate system, forming a combined coordinate system, that is, a simulated coordinate has two coordinates. The specific undisclosed part is common knowledge in this field.

[0062] To simulate transmission environment data, the method is to obtain possible transmission environment data based on historical power grid data, and then set simulation coordinates according to the method of establishing the influencing positioning coordinates.

[0063] Clustering is performed based on the transformed coordinates, and the expert group sets the corresponding clustering constraints, and clustering is performed based on the existing clustering algorithm.

[0064] Converting it into the corresponding positioning matching map is to convert the coordinate system data into an image.

[0065] The method of associating the corresponding signal anti-interference segment storage library according to the established positioning matching graph includes:

[0066] Identify the labels of each area in the positioning matching map, set the feature data corresponding to each coordinate area, set the corresponding signal anti-interference segment according to the acquired feature data, summarize and establish a signal anti-interference segment storage library, and associate the signal anti-interference segments stored in the signal anti-interference segment storage library with the corresponding coordinate areas in the positioning matching map.

[0067] Setting the characteristic data corresponding to each coordinate area and setting the corresponding signal anti-interference segment according to the acquired characteristic data can be done through existing methods, which is common knowledge in the field and will not be described in detail.

[0068] Step 3: Output the open contact corresponding to the control signal.

[0069] Signal output is achieved through relays. Due to their unique electrical and physical properties in control circuits, relays possess high insulation resistance in the off-state and low on-resistance in the on-state, making them unmatched by any other electronic component. Furthermore, relays offer advantages such as high standardization, versatility, and simplified circuitry, making them a key element in the design of intelligent output modules. Each output hard contact must correspond to one device state.

[0070] The above formulas are all calculated by removing dimensions and taking their numerical values. The formula is a formula that is closest to the actual situation obtained by collecting a large amount of data and performing software simulation. The preset parameters and preset thresholds in the formula are set by technicians in this field according to actual conditions or obtained by simulating a large amount of data.

[0071] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
