Description

Technical Field

[0001] This invention relates to the field of power system automation technology, specifically to a method, device, and medium for comparing information from multiple forwarding tables and multiple channels. Background Technology

[0002] Currently, substation monitoring information acceptance relies on manual verification, which suffers from long acceptance cycles and heavy workloads. To address these issues, automated acceptance devices are being gradually implemented. Different master stations use different forwarding tables, typically with varying signal counts and ordering, and a large number of channels and signals. Existing automated acceptance devices do not automatically compare information from multiple forwarding tables and channels. When using automated acceptance devices to simulate master station receiving monitoring information, acceptance personnel must simultaneously verify information from all master stations and all channels, resulting in a heavy workload and increasing the risk of missed or incorrect verifications. Summary of the Invention

[0003] This invention provides a method, device, and medium for comparing multiple forwarding tables and multiple channel information, so as to realize the function of automatic acceptance device to automatically compare multiple forwarding tables and multiple channel information.

[0004] This invention is achieved through the following technical solution:

[0005] A method for comparing information from multiple forwarding publications and multiple channels includes:

[0006] S1. The source device forwards a time-stamped signal to the automatic acceptance device through the telemetry system. When any channel connected to the automatic acceptance device receives a signal forwarded by the telemetry system, it finds the channel with the same time-stamped signal among all channels connected to the automatic acceptance device except the channel itself, and compares whether the point numbers of the signals of each channel in the same forwarding table are consistent. It also compares whether the text description information corresponding to the signals of each channel in different forwarding tables is consistent. If they are all consistent, it jumps to S2. Otherwise, it is determined that the channel information is inconsistent and it jumps to S4.

[0007] S2. Check each channel that did not receive the signal in all channels between the remote control system and the automatic acceptance device, find the monitoring information table corresponding to the channel that did not receive the signal, and check whether the signal is in the monitoring information table corresponding to the channel that did not receive the signal. If the signal is not in the corresponding monitoring information table, the remote control system is judged to be forwarding normally and jump to S3; otherwise, the remote control system is judged to be forwarding abnormally and jump to S4.

[0008] S3. Determine whether all channels that have not received the signal among all channels connected to the automatic acceptance device have been checked. If so, determine that all channels that have not received the signal are forwarding normally, and the acceptance personnel shall manually confirm the result. Otherwise, proceed to S2.

[0009] S4. Investigate the problem.

[0010] As an optimization, the text description information of the signal is in Chinese.

[0011] As an optimization, the time stamp format is: hour:minute:second:millisecond.

[0012] As an optimization, the time scale uses a 24-hour system.

[0013] As an optimization, the automatic acceptance device can automatically accept and compare information accessed from multiple different master stations.

[0014] As an optimization, the automatic acceptance device is connected to the remote control system via a network cable, and a single network cable contains multiple channels.

[0015] As an optimization, the specific process of S1 is as follows:

[0016] S1.1 The source device sends a time-stamped signal to the remote control system, and the remote control system uses the signal as a corresponding trigger signal;

[0017] S1.2. Find the intermediate information in the forwarding configuration information of the telemetry system that matches the trigger signal according to the trigger signal, and forward the point number corresponding to the intermediate information and the time stamp corresponding to the signal sent by the source device to the automatic acceptance device. The table formed by exporting the forwarding configuration information of the telemetry system is a forwarding table.

[0018] S1.3 When any channel connected to the automatic acceptance device receives the point number and time stamp forwarded by the remote control system, the channel with the same time stamp is found among all channels connected to the automatic acceptance device except for that channel, according to the time stamp.

[0019] S1.4. Among all the identified channels, compare the point numbers of channels belonging to the same forwarding table to determine whether the point numbers of channels belonging to the same forwarding table are consistent. At the same time, compare the point numbers of channels belonging to different forwarding tables with the point numbers of the corresponding monitoring information tables of each forwarding table to find the text description information of the signal in the corresponding monitoring information table and determine whether the text description information corresponding to the point numbers of channels belonging to different forwarding tables is consistent.

[0020] As an optimization, the specific steps of S2 are as follows:

[0021] S2.1 When any channel connected to the automatic acceptance device receives the point number and time stamp forwarded by the remote control system, the channel with the same time stamp is found among all channels connected to the automatic acceptance device except for that channel.

[0022] S2.2 Check in the monitoring information table corresponding to the identified channel whether there is a signal with the same text description information as the signal;

[0023] S2.3 If there is no signal with the same textual description information as the signal in the corresponding monitoring information table, the remote control system is judged to be forwarding normally and jumps to S3; otherwise, the remote control system is judged to be forwarding abnormally and jumps to S4.

[0024] The present invention also discloses an electronic device, including at least one processor and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform a comparison method for multiple forwarding tables and multiple channels of information as described above.

[0025] The present invention also discloses a storage medium storing a computer program, which, when executed by a processor, implements a method for comparing multiple forwarding tables and multiple channels of information as described above.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] When using an automatic acceptance device to simulate the acceptance of multi-channel information from different master stations, the automatic comparison method proposed in this invention can automatically verify whether all channels are forwarding normally and whether the channel information is consistent. After verifying that the forwarding is normal, the acceptance personnel only need to obtain the text description information and / or values ​​corresponding to the actual signal given by the debugging personnel and compare them with one of the channels containing the information in the automatic acceptance device. This greatly reduces the workload of the acceptance personnel and significantly improves the efficiency and accuracy of the acceptance work.

[0028] This method can be used not only for substation-side simulation of master station acceptance monitoring information, but also for master station acceptance monitoring information, and is suitable for comparison of multi-forwarding tables and multi-channel information in various scenarios. Attached Figure Description

[0029] To more clearly illustrate the technical solutions of the exemplary embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below. It should be understood that the following drawings only show some embodiments of the present invention and should not be considered as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort. In the drawings:

[0030] Figure 1 This is a schematic diagram showing the connection between the automatic acceptance device and the remote control system in this embodiment;

[0031] Figure 2 This is a flowchart illustrating the method for comparing multiple forwarding tables and multiple channels of information as described in this invention. Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0033] Before describing specific embodiments, the following terms will be explained:

[0034] Automatic acceptance device: A dedicated automatic acceptance device for connecting substation monitoring information to the smart grid control / centralized control system.

[0035] Monitoring Information Table: A summary table of information collected by substations connected to the dispatching / centralized control system.

[0036] Forwarded from: A table describing the correspondence between substation terminal information and dispatch terminal information in remote control.

[0037] Since a signal emitted by the source device is forwarded by the telemetry system and transmitted outward through multiple channels, if the channel configuration is incorrect, the timestamp of the signal forwarded by that channel will remain unchanged, but the point number will change. Therefore, the method of this invention can quickly compare information from multiple forwarding tables and multiple channels. Next, the method of this invention will be described in detail. Before comparison, the communication parameters, monitoring information tables, and forwarding tables of each channel need to be imported into the automatic acceptance device.

[0038] The forwarding table is a table describing the correspondence between substation end information and dispatch end information in the remote control system. It is a table exported from the remote control system after the manufacturer configures the remote control system. The monitoring information table is provided by the design.

[0039] Each master station corresponds to one monitoring information table. Each master station has multiple communication channels with the remote control system (RTS), and each channel corresponds to a forwarding table. Depending on the configuration, multiple channels can correspond to the same forwarding table, or one channel can correspond to one forwarding table. The RTS and channel configuration is completed by the backend manufacturer.

[0040] like Figure 1-2 As shown in Example 1, a method for comparing multiple forwarding tables and multiple channels of information includes:

[0041] S1. The source device forwards the time-stamped signal to the automatic acceptance device via the remote control system. There are various types of source devices, and there are multiple reasons why a source device might emit a time-stamped signal. One reason is that the source device may generate certain signals without needing to collect the signal itself. When any channel connected to the automatic acceptance device receives a signal, it identifies all channels connected to the automatic acceptance device (excluding the channel with the time stamp) that have the same time stamp based on the signal's time stamp. It then compares the point numbers of the signals from each channel in the same forwarding table to see if they are consistent, and compares the text description information corresponding to the signals from each channel in different forwarding tables to see if they are consistent. If they are all consistent, it jumps to S2; otherwise, it determines that the channel information is inconsistent and jumps to S4. The time stamping of the signal is a mechanism of the device itself. When the device collects or generates a signal, it assigns it the current time. The time stamp format is: hour:minute:second:millisecond, using a 24-hour system. The source device (acquisition device) collects and emits signals. Theoretically, two or more signals may be triggered simultaneously. However, since the time scale of this invention is accurate to milliseconds, it can be considered that only one signal is triggered per millisecond. Therefore, within the same millisecond, the signal is unique, and thus, the Chinese description of the signal corresponding to the same time scale is also unique. The telemetry system has multiple channels. After a signal enters the telemetry system, it will be forwarded to its respective endpoint through each channel.

[0042] The automatic acceptance testing (ACP) device is placed in the substation and connected to the remote control (TDC) output terminal to simulate the master station. (The TDC output signal is sent to the master station, and the ACP device is used to simulate the master station receiving the signal). The ACP device is connected to the TDC via a network cable. Generally, one TDC uses two network cables, and one network cable contains multiple communication channels.

[0043] The source device emits a time-stamped signal, which is then forwarded to the automatic acceptance testing device via a remote control system. When any channel connected to the automatic acceptance testing device receives a signal, the system identifies all channels connected to the automatic acceptance testing device (excluding the channel with the same timestamp) based on the signal's timestamp, and compares the textual descriptions of these signals with the same timestamp to see if they are consistent. The specific process is as follows:

[0044] S1.1 The source device sends a time-stamped signal to the remote control system, and the remote control system uses the signal as a corresponding trigger signal;

[0045] S1.2. Find the intermediate information in the forwarding configuration information of the telemetry system that matches the trigger signal according to the trigger signal, and forward the point number corresponding to the intermediate information and the time stamp corresponding to the signal sent by the source device to the automatic acceptance device. The table formed by exporting the forwarding configuration information of the telemetry system is a forwarding table.

[0046] S1.3 When any channel connected to the automatic acceptance device receives the point number and time stamp forwarded by the remote control system, the channel with the same time stamp is found among all channels connected to the automatic acceptance device except for that channel, according to the time stamp.

[0047] S1.4. Among all the identified channels, compare the point numbers of channels belonging to the same forwarding table to determine whether the point numbers of channels belonging to the same forwarding table are consistent. At the same time, compare the point numbers of channels belonging to different forwarding tables with the point numbers of the corresponding monitoring information tables of each forwarding table to find the text description information of the signal in the corresponding monitoring information table and determine whether the text description information corresponding to the point numbers of channels belonging to different forwarding tables is consistent.

[0048] S2. Check each channel that has not received the signal among all channels connected to the automatic acceptance device, find the monitoring information table corresponding to the channel that has not received the signal, and check whether the signal is in the corresponding monitoring information table. If the signal is not in the corresponding monitoring information table, the remote control system is judged to be normal and jump to S3. Otherwise, the remote control system is judged to be abnormal and jump to S4.

[0049] The specific steps are as follows:

[0050] S2.1 When any channel connected to the automatic acceptance device receives the point number and time stamp forwarded by the remote control system, the channel with a signal that does not have the same time stamp is found among all channels connected to the automatic acceptance device except for that channel, according to the time stamp.

[0051] S2.2 Check in the monitoring information table corresponding to the identified channel whether there is a signal with the same text description information as the signal;

[0052] S2.3 If there is no signal with the same textual description information as the signal in the corresponding monitoring information table, the telecontrol system is judged to be forwarding normally, and the process jumps to S3; otherwise, the telecontrol system is judged to be forwarding abnormally, and the process jumps to S4.

[0053] S3. Determine whether all channels that have not received the signal among all channels connected to the automatic acceptance device have been checked. If so, determine that all channels that have not received the signal are forwarding normally, and the acceptance personnel shall manually confirm the result. Otherwise, proceed to S2.

[0054] S4. Investigate the problem.

[0055] In this embodiment, the automatic acceptance device can automatically compare information from multiple different master stations. Furthermore, the automatic acceptance device can correspond to multiple telemetry systems through different channels. More specifically, the automatic acceptance device has multiple input ports, each input port corresponding to the output port of the telemetry system through several channels, and the channels corresponding to one input port correspond to one or more master stations.

[0056] In simple terms, the process of this invention is as follows:

[0057] The source devices (merging unit, intelligent terminal, protection, measurement and control, etc.) send time-stamped signals to the remote control unit (RCU). Finally, the RCU sends the signals to the dispatch / centralized control master station. The time stamps of signals transmitted from the same source to each dispatch / centralized control master station through their respective corresponding channels are consistent.

[0058] To simulate the main station's acceptance monitoring information using an automatic acceptance testing device, firstly, configure all channels of the automatic acceptance testing device and import the monitoring information table and forwarding table. Then, connect the remote control output signal network port to the automatic acceptance testing device's simulated main station network port via a network cable. Information is transmitted through the channel via the network cable. The connection between the automatic acceptance testing device and the remote control is as follows: Figure 1 As shown.

[0059] The automatic comparison method is as follows:

[0060] Step 1: When any channel of the automatic acceptance device receives a signal, it finds the signal with the same time stamp in other channels based on the time stamp of the signal, compares the point numbers of each channel in the same forwarding table, and compares the Chinese descriptions of the signals of channels in different forwarding tables. If the point numbers of the signals of each channel in the same forwarding table are consistent and the Chinese descriptions of the signals of channels in different forwarding tables are consistent, then the second step of the check is performed; otherwise, the channel information is judged to be inconsistent.

[0061] For example, points 1 and 30 in the monitoring information table are supposed to be different, but the Chinese descriptions of the two points are mistakenly written as the same. If one channel forwards point 1 normally, while another channel (belonging to the same forwarding table as the aforementioned channel) incorrectly forwards point 30, simply comparing the Chinese descriptions will not reveal the problem. Although the probability of this kind of problem is small, this comparison can prevent it from happening. Therefore, point numbers should be compared for each channel corresponding to the same forwarding table (or monitoring information table), and the text descriptions of signals for channels between different forwarding tables should be compared. If they are all consistent, and the monitoring information table corresponding to the channel that did not receive the signal does not contain that signal, it indicates that the signal is correct. If a channel forwarding is normal and the channel information is consistent, but the point numbers of channels belonging to the same forwarding table are different, but the text description information corresponding to the signals of channels in different forwarding tables is the same, it indicates that there is a problem with the monitoring information table and telecontrol forwarding configuration corresponding to the channels with different point numbers; if the point numbers of channels belonging to the same forwarding table are different, and the text description information of channels belonging to that forwarding table is different, it indicates that there is a problem with the corresponding telecontrol forwarding configuration; if the point numbers of channels belonging to the same forwarding table are the same, and the text description information of channels belonging to that forwarding table is also the same, but the text description information of channels belonging to different forwarding tables is different, then the forwarding table and monitoring information table need to be checked.

[0062] Step 2: Check all channels that did not receive the signal. Since the checking method is the same, we will use the checking process for one channel as an example: First, locate the monitoring information table corresponding to the channel. Then, check if the signal exists in the corresponding monitoring information table. If the signal is not found in the corresponding monitoring information table, the telemetry forwarding is considered normal; otherwise, the telemetry forwarding is considered abnormal. If all channels that did not receive the signal forward normally, proceed to Step 3, where the acceptance personnel manually confirm the results.

[0063] The first two steps verify whether all channels are normal and whether the channel information is consistent. The acceptance personnel can complete the final confirmation based on the comparison results and the actual trigger signal information obtained from the debugging personnel, which is the third step.

[0064] Step 3: The acceptance personnel obtain the actual trigger signal information from the commissioning personnel and compare it with the description of the signal received from one of the channels. If the two match, the acceptance can be confirmed as passed; otherwise, the reason for the inconsistency needs to be found.

[0065] Automatic comparison process as follows Figure 2 As shown.

[0066] Next, specific examples will be used to further illustrate the method of the present invention.

[0067] Case 1:

[0068] Taking the acceptance testing of three main stations as an example, it involves two remote control systems, 24 channels, three monitoring information tables, and three forwarding tables. An additional forwarding table is added to set error points.

[0069] Master station A corresponds to Monitoring Information Table A, Forwarding Table A, and Channels 1-8; Master station B corresponds to Monitoring Information Table B, Forwarding Table B, and Channels 9-16; Master station C corresponds to Monitoring Information Table C, Forwarding Table C, and Channels 17-24. The Chinese descriptions for point 11 in Monitoring Information Table A and point 21 in Monitoring Information Table B are both "Operator working position," and the Chinese description for point 31 in Monitoring Information Table B is "Maintenance status." This point is not present in Monitoring Information Table C. Channels 1-8 correspond to Forwarding Table A, Channels 10-16 correspond to Forwarding Table B, and Channels 17-24 correspond to Forwarding Table C. Point 11 in Forwarding Table A and point 21 in Forwarding Table B forward the signal "Operator working position," but this point is not present in Forwarding Table C. Channel 9 corresponds to forwarding table D. Forwarding table D forwards the signal "handcart working position" at point 31 and the signal "maintenance status" at point 21. The rest of the information is the same as that in forwarding table B. (Forwarding table D corresponds to monitoring information table B. Theoretically, forwarding table D and forwarding table B are the same forwarding table, just set for different channels. Therefore, the same trigger signal will forward the same message at the same point number triggered by forwarding table B and forwarding table D. That is, at the same time, it will trigger point 21 of forwarding table B and point 31 of forwarding table D. Since both forwarding table B and D correspond to monitoring information table B, the Chinese descriptions corresponding to channels 1-8 are different from those corresponding to channel 9, and the point numbers corresponding to channels 10-16 are different from those corresponding to channel 9.)

[0070] The above error is a telecontrol configuration error, which reverses the configuration of points 21 and 31 in forwarding table D, which belongs to the same monitoring information table as forwarding table B.

[0071] The advantage of using time-based positioning signals is that even if someone happens to trigger point 21 of forwarding table D at this time, channel 9 will also report point 21. This signal can be ruled out by using the time stamp, because the time is accurate to milliseconds, and it is virtually impossible for them to be simultaneous.

[0072] Step 1: When the automatic acceptance device channel 1 receives the "handcart working position" at 11 o'clock, with the time stamp "11:22:33.303", search for the signal with the time stamp "11:22:33.303" in channels 2-24. Channels 2-8 and 9-16 are found.

[0073] Step 2: Compare the point numbers of the signals in channels 1-8 with a time stamp of "11:22:33.303" to see if they match. Compare the point numbers of the signals in channels 9-16 with a time stamp of "11:22:33.303" to see if they match. Compare the Chinese descriptions of all signals with a time stamp of "11:22:33.303" to see if they match. Since the point number of the signal with a time stamp of "11:22:33.303" in channel 9 is "31", and the Chinese description of the signal in the corresponding monitoring information table B is "under maintenance status", which is different from the point number of the signal with a time stamp of "11:22:33.303" in channels 10-16, and different from the Chinese description of the signal with a time stamp of "11:22:33.303" in channels 1-8 and 10-16, at this time, an "Inconsistent Channel Information" message will be reported, prompting the acceptance personnel to find the problem.

[0074] Case 2: Master station A corresponds to monitoring information table A, forwarding table A, and channels 1-8; master station B corresponds to monitoring information table B, forwarding table B, and channels 9-16; master station C corresponds to monitoring information table C, forwarding table C, and channels 17-24. The Chinese description of point 11 in monitoring information table A and point 21 in monitoring information table B is "handcart working position." Point 31 in monitoring information table B is set to "handcart working position" as the fault point; this point is not present in monitoring information table C. Forwarding table A forwards the signal "handcart working position" at point 11 and forwarding table B forwarding the signal "handcart working position" at point 21; this point is not present in forwarding table C. Channel 9 corresponds to forwarding table D. Forwarding table D forwards the signal "handcart working position" at point 31 and "maintenance status" at point 21; the remaining information is the same as in forwarding table B.

[0075] Step 1: When the automatic acceptance device channel 1 receives the "handcart working position" at 11 o'clock, with the time stamp "11:22:33.303", search for the signal with the time stamp "11:22:33.303" in channels 2-24. Channels 2-8 and 9-16 are found.

[0076] Step 2: Compare the point numbers of signals in channels 1-8 with a time stamp of "11:22:33.303" to see if they are consistent. Compare the point numbers of signals in channels 9-16 with a time stamp of "11:22:33.303" to see if they are consistent. Compare the Chinese descriptions of all signals with a time stamp of "11:22:33.303" to see if they are consistent. At this point, the Chinese descriptions of the signals with a time stamp of "" in channels 1-16 are all "handcart working position", and the fault cannot be found by comparing the Chinese descriptions alone. Since the point number of the signal with a time stamp of "11:22:33.303" in channel 9 is 31, while the point number of the signal with a time stamp of "11:22:33.303" in channels 10-16 is 21, the two are inconsistent, and the report "channel information inconsistent" is issued, prompting the acceptance personnel to find the problem.

[0077] Case 3:

[0078] Taking the acceptance of three main stations as an example, it involves two remote control systems, 24 channels, three monitoring information tables, and three forwarding tables.

[0079] Main station A corresponds to monitoring information table A, forwarding table A, and channels 1-8; main station B corresponds to monitoring information table B, forwarding table B, and channels 9-16; and main station C corresponds to monitoring information table C, forwarding table C, and channels 17-24. Point 11 in forwarding table A and point 21 in forwarding table B both have the Chinese description "handcart working position," but this point is not present in forwarding table C.

[0080] Step 1: When the automatic acceptance device channel 1 receives the "handcart working position" at 11 o'clock, with the time stamp "11:22:33.303", search for the signal with the time stamp "11:22:33.303" in channels 2-24, and channel 2-16 will be found.

[0081] Step 2: Compare the signal point numbers in channels 1-8 with the time stamp "11:22:33.303" to see if they match. Compare the signal point numbers in channels 9-16 with the time stamp "11:22:33.303" to see if they match. Compare the Chinese descriptions of all signals with the time stamp "11:22:33.303" to see if they match. At this point, the signal point numbers in channels 1-8 with the time stamp "11:22:33.303" match, the signal point numbers in channels 9-16 with the time stamp "11:22:33.303" match, and the Chinese description of the signal in channels 1-16 with the time stamp "11:22:33.303" is "handcart working position". The channel information is consistent, so proceed to the next step.

[0082] Step 3: Channels 17-24 did not receive a signal with the timestamp "11:22:33.303". Check the corresponding monitoring information table C for a signal with the Chinese description "handcart working position". Since there is no signal with the Chinese description "handcart working position" in monitoring information table C, the remote control forwarding is normal, proceed to the next step.

[0083] Step 4: The acceptance personnel obtain the actual trigger signal "handcart working position" from the commissioning personnel. Therefore, the automatic acceptance device confirms that the signal has passed the acceptance test.

[0084] Example 2 also discloses an electronic device, including at least one processor and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform a comparison method for multiple forwarding tables and multiple channels of information as described in Example 1.

Check each channel that did not receive the signal in all channels between the remote control system and the automatic acceptance device, find the monitoring information table corresponding to the channel that did not receive the signal, and check whether the signal is in the monitoring information table corresponding to the channel that did not receive the signal. If the signal is not in the corresponding monitoring information table, the remote control system is judged to be forwarding normally and jump to S3; otherwise, the remote control system is judged to be forwarding abnormally and jump to S4. S3. Determine whether all channels that have not received the signal among all channels connected to the automatic acceptance device have been checked. If so, determine that all channels that have not received the signal are forwarding normally, and the acceptance personnel shall manually confirm the result. Otherwise, proceed to S2. S4. Investigate the problem.

2. The method of claim 1, wherein, The text description information for the signal is in Chinese.

7. The method for comparing multiple forwarding tables and multi-channel information according to claim 6, characterized in that, The specific process of S1 is as follows: S1.1 The source device sends a time-stamped signal to the remote control system, and the remote control system uses the signal as a corresponding trigger signal; S1.

2. Find the intermediate information in the forwarding configuration information of the telemetry system that matches the trigger signal according to the trigger signal, and forward the point number corresponding to the intermediate information and the time stamp corresponding to the signal sent by the source device to the automatic acceptance device. The table formed by exporting the forwarding configuration information of the telemetry system is a forwarding table. S1.3 When any channel connected to the automatic acceptance device receives the point number and time stamp forwarded by the remote control system, the channel with the same time stamp is found among all channels connected to the automatic acceptance device except for that channel, according to the time stamp. S1.

4. Among all the identified channels, compare the point numbers of channels belonging to the same forwarding table to determine whether the point numbers of channels belonging to the same forwarding table are consistent. At the same time, compare the point numbers of channels belonging to different forwarding tables with the point numbers of the corresponding monitoring information tables of each forwarding table to find the text description information of the signal in the corresponding monitoring information table and determine whether the text description information corresponding to the point numbers of channels belonging to different forwarding tables is consistent.

8. The method for comparing multiple forwarding tables and multi-channel information according to claim 1, characterized in that, The specific steps of S2 are as follows: S2.1 When any channel connected to the automatic acceptance device receives the point number and time stamp forwarded by the remote control system, the channel with the same time stamp is found among all channels connected to the automatic acceptance device except for that channel. S2.2 Check in the monitoring information table corresponding to the identified channel whether there is a signal with the same text description information as the signal; S2.3 If there is no signal with the same textual description information as the signal in the corresponding monitoring information table, the remote control system is judged to be forwarding normally and jumps to S3; otherwise, the remote control system is judged to be forwarding abnormally and jumps to S4.
