TECHNICAL FIELD
[0001] The present application belongs to the technical field of new energy station, and particularly relates to a station and centralized control master station signal point acceptance method, a station internal acceptance device and a centralized control master station. BACKGROUND
[0002] At present, with the gradual planning and construction of new energy centralized control station systems of new energy power generation enterprises, new energy intelligent station monitoring systems facing the monitoring and control of new energy power generation equipment operation status need to realize information "full access". The access convenience is highlighted, and the access signal automatic verification function is provided to realize the non-power-off access of the existing new energy station. The information interaction between the new energy centralized control station system and the new energy station end is completely carried out by manual mode, which is a huge checking workload, resulting in high labor cost and low efficiency.
[0003] In order to solve the problem, a method for automatically accepting telemetry and remote control signals between a new energy station and a centralized control master station is proposed in a Chinese patent application with the application publication number CN117767564A. This method can improve the efficiency of signal acceptance, liberate labor, and reduce labor cost. However, this technical solution cannot verify remote signal, especially the remote signal of the merging point. SUMMARY
[0004] The purpose of the present application is to provide a station and centralized control master station signal point acceptance method, a station internal acceptance device and a centralized control master station to solve the technical problem that the prior art cannot verify remote signal data.
[0005] To solve the above technical problems, the present application provides a station and centralized control master station signal point acceptance method, which comprises the following steps:
[0006] 1) After the station internal acceptance device verifies that there is no error, the station internal acceptance device sends a control instruction to the centralized control master station to make all remote signal points of the centralized control master station in an initial state;
[0007] 2) The station internal acceptance device sends an acceptance instruction of the to-be-tested remote signal point to the centralized control master station, and the acceptance instruction includes a position change instruction that makes the to-be-tested remote signal point in a state opposite to the initial state;
[0008] 3) The centralized control master station determines the point number of the to-be-tested remote signal point according to the received acceptance instruction, and judges whether the actual change of the to-be-tested remote signal point with the point number in the centralized control master station conforms to the position change instruction in the acceptance instruction. If it conforms, the to-be-tested remote signal point acceptance is correct, and if it does not conform, the to-be-tested remote signal point acceptance is incorrect.
[0009] Further, when the to-be-tested remote signal point is an independent remote signal point, the initial state is a split state or a combined state.
[0010] Further, when the to-be-tested remote signaling point is a combined point of OR operation, the initial state is a split state.
[0011] The acceptance instruction in step 2) includes acceptance instructions of each sub-signal of the combined point in turn, and each acceptance instruction of the sub-signal includes a change instruction for making the to-be-tested remote signaling point in an opposite state to the initial state and a change instruction for making the to-be-tested remote signaling point in the same state as the initial state, and the change instruction for making the to-be-tested remote signaling point in the opposite state to the initial state is located before the change instruction for making the to-be-tested remote signaling point in the same state as the initial state.
[0012] Further, when the to-be-tested remote signaling point is a combined point of AND operation, the initial state is a combined state.

[0014] Further, the acceptance instruction further includes a change instruction for making the remote signaling point in the same state as the initial state, and the change instruction for making the remote signaling point in the same state as the initial state is located after the change instruction for making the remote signaling point in the opposite state to the initial state.
[0015] Further, the second bit plus the millisecond bit of the time label of the acceptance instruction is equal to the verification sequence number of the to-be-tested remote signaling point, and correspondingly, the method for the centralized master station to determine the point number of the to-be-tested remote signaling point according to the received acceptance instruction is that: the verification sequence number of the to-be-tested remote signaling point is determined according to the second bit plus the millisecond bit of the time label of the acceptance instruction, and the point number of the to-be-tested remote signaling point is determined according to the verification sequence number of the to-be-tested remote signaling point.
[0016] Further, the verification of the on-site acceptance device includes communication consistency verification of the on-site acceptance device and the centralized master station, and consistency check of the point table model of the on-site acceptance device and the centralized master station.
[0017] Further, the acceptance method further includes the following steps:
[0018] The on-site acceptance device interrupts the communication of a certain device in the field station and then restores it, and if the centralized master station detects that the communication of the certain device is interrupted and then restored, the communication interruption verification of the certain device is correct.
[0019] Further, the acceptance method further includes the following steps:
[0020] The field station acceptance device sends acceptance data of the telemetry point to the centralized master station, the acceptance data is the verification point number of the to-be-tested telemetry point plus an offset, the centralized master station compares the received acceptance data with the verification point number of the to-be-tested telemetry point plus the offset, if the two are consistent, the to-be-tested telemetry point is verified to be correct, otherwise the to-be-tested telemetry point is verified to be incorrect.
[0021] Further, the acceptance method further comprises the following steps:
[0022] The field station acceptance device sets all remote control point positions to the split state, and sends split state instructions of all remote control point associated remote signaling point positions to the centralized master station and the monitoring background; the monitoring background sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device, the centralized master station sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device; the centralized master station sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device, the monitoring background sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device; the field station acceptance device compares the received control content of the monitoring background and the control content of the centralized master station, if it conforms to the expected judgment logic, the to-be-tested remote control point is verified to be correct, if it does not conform to the expected judgment logic, the to-be-tested remote control point is verified to be incorrect.
[0023] Further, the acceptance method further comprises the following steps:
[0024] The field station acceptance device sets all remote control point positions to the split state, and sends split state instructions of all remote control point associated remote signaling point positions to the centralized master station and the monitoring background; the monitoring background sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device, the centralized master station sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device; the monitoring background sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device, the centralized master station sends control content including the to-be-tested remote control point sending split state preset order and remote control cancel order to the field station acceptance device; the field station acceptance device compares the received control content of the monitoring background and the control content of the centralized master station, if it conforms to the expected judgment logic, the to-be-tested remote control point is verified to be correct, if it does not conform to the expected judgment logic, the to-be-tested remote control point is verified to be incorrect.

[0040] In order to make the purpose, technical scheme and advantages of the invention clearer and more explicit, the invention will be further described in detail below in combination with the drawings and examples.
[0041] Embodiment of the yard and centralized control master station signal point acceptance method:
[0042] The yard and centralized control master station signal point acceptance method of the invention includes the following steps:
[0043] Step one: build an acceptance environment.
[0044] In this embodiment, the field station is taken as a new energy field station, the centralized control master station is a new energy centralized control station, the acceptance device in the field station is an automatic point-to-point device for point-to-point testing of a simulated new energy field station terminal device model (hereinafter also referred to as an automatic point-to-point device), the automatic point-to-point device is physically isolated from the actual operating environment of the new energy field station, the automatic point-to-point device simulates the operation of the equipment in the new energy field station during point-to-point testing, and the corresponding equipment in the actual operating environment does not operate, so that point-to-point testing can be performed without affecting the operation of the actual new energy field station.
[0045] The automatic acceptance environment built is shown in Figure 1 The automatic point-to-point device is connected to the acceptance device through a gateway machine, and the automatic point-to-point device is also connected to a monitoring background, a new energy centralized control station and the monitoring background.
[0046] Due to the different operating conditions of actual new energy field stations, there are normally operating new energy field stations and newly built centralized control field stations, and therefore, in order to ensure that the operation of the new energy field station is not affected, the acceptance device and the actual equipment in the new energy field station are isolated in this embodiment to avoid affecting the normal operation of the new energy field station.
[0047] The model of the automatic point-to-point device of the new energy field station is verified, and the verification content includes model consistency verification and communication consistency verification. The consistency of the new energy field station model and the centralized control station model is checked.
[0048] The model consistency verification content includes checking of the index, description and important attributes of the measuring point. The communication consistency checking content includes correctness verification of the measuring point number, description and sequence in the master point table. The communication consistency verification refers to the fact that the data sent by the field station end automatic acceptance device and the data finally obtained by the centralized control master station end automatic acceptance system should be consistent after transmission, transmission, reception, analysis and processing through the intermediate communication channel, including consistency of the numerical value, consistency of the data point number and consistency of the data sequence.
[0049] The model consistency check refers to the consistency check of the telemetering, telesignaling, remote control and remote adjustment point table model information sent by the field station end to the centralized control master station system and the model information stored in the database of the centralized control master station, and the check content includes static attributes such as information point description, path, point number and measuring point type.
[0050] Step 2: Check the station end forwarding table.
[0051] The purpose of the station end forwarding table check is to check whether the forwarding table configuration information running in the station end gateway machine is consistent with the point table information configured in the new energy centralized control station, mainly to check the static attributes of the electric meter, and the check content includes attribute information such as point number, description, path, coefficient, single / double point, alarm level, etc. The specific checking method is as follows:
[0052] The forwarding table configuration information running in the station gateway machine is automatically or manually stored in the designated directory of the central control master station. The station acceptance system imports the forwarding table file for parsing and display, and performs static attribute information verification between the forwarding table information and the measurement point information of the station in the central control master station database, generates a verification report, and supports the export of the verification report.
[0053] Step 3: Perform automatic acceptance testing on remote signaling information.
[0054] During acceptance testing, the automatic alignment device first sets all remote signaling measurement points to their initial state. Then, the automatic alignment device sends acceptance instructions for each remote signaling point to the acceptance system of the new energy central control station via the gateway. The acceptance instructions include repositioning instructions that cause the remote signaling point to be measured to be in the opposite state to its initial state. The acceptance system of the new energy central control station verifies the remote signaling information based on the received repositioning instructions and the actual repositioning situation of the central control station.
[0055] In this embodiment, the number of milliseconds in the SOE timestamp of a remote signaling point is associated with the verification sequence number of the remote signaling point to be tested. Specifically, the number of milliseconds in the SOE timestamp of the transmitted remote signaling information is equal to the verification sequence number of the remote signaling point (if the sequence number exceeds 1000, it is distinguished by the number of seconds). For example, the millisecond part of the SOE timestamp of the acceptance instruction for the 10th verified remote signaling point is 10; the second part of the SOE timestamp of the acceptance instruction for the 1010th verified remote signaling point is 1, and the millisecond part is 10.
[0056] During verification, the new energy central control station acceptance system determines the verification sequence number of the remote signaling point to be tested based on the millisecond part of the timestamp of the acceptance command (if it exceeds 1000, the second value is considered). Correspondingly, the central control master station judges the correctness of the acceptance point sequence number by comparing the millisecond part of the timestamp of the received acceptance command (if it exceeds 1000, the second value is considered) with the verification sequence number of the remote signaling point to be tested.
[0057] In this embodiment, the centralized control station acceptance system performs acceptance testing by detecting the changes in its remote signaling signals and combining this with the remote signaling point number of the received change command, the SOE time stamp in milliseconds, and the change signal. The interval between verifications of every two remote signaling points is approximately 400ms, and the remote signaling value change signal follows a "split-combination-split" pattern. The specific detection process is as follows: Figure 2 As shown, this includes the detection of independent remote signaling points, the detection of merged remote signaling points, and the acceptance of communication interruptions at remote signaling points.
[0058] 3.1 The detection of independent remote signaling points includes the following steps:
[0059] 3.1.1 The automatic point-to-point device in the new energy power station sends control commands for all independent remote signaling points to the automatic point-to-point system of the central control station through the gateway to set all remote signaling point positions to the initial state.
[0060] In this embodiment, the initial state is the split state. In other implementations, the initial state for independent remote signaling point detection can also be the combined state.
[0061] 3.1.2. Send the corresponding acceptance command to each remote signaling point according to the point number sequence of the current remote signaling points to be tested. The milliseconds of the timestamp of the acceptance command are equal to the point number of that remote signaling point.
[0062] In this embodiment, the acceptance instruction includes a merging instruction and a splitting instruction, with the merging instruction preceding the splitting instruction. In other embodiments, the acceptance instruction should include at least one instruction that is opposite to the initial state, and the instruction that is opposite to the initial state may be followed by an instruction that is the same as the initial state.
[0063] 3.1.3 The automatic point-to-point system of the central control station determines the sequence number of the remote signaling point to be tested based on the number of milliseconds of the acceptance command, and compares the action status of the remote signaling point to be tested with the acceptance command to determine whether the remote signaling point to be tested has been verified correctly.
[0064] In this embodiment, the initial state is a combined state. Therefore, the command first specifies the separation command and then the combination command. If the state change of the remote signaling point to be tested is first separation and then combination, which is consistent with the expected change in the command, then the verification of the point to be tested is correct. In other implementations, it is sufficient to determine that the verification of the point to be tested is correct as long as the state change of the remote signaling point to be tested corresponds to the acceptance command.
[0065] 3.1.4 Repeat steps 3.1.1 to 3.1.3 until all independent remote signaling points have been tested.
[0066] 3.2 Verification of non-independent remote signaling points:
[0067] Non-independent remote signaling points are called merging points. The state of a merging point is controlled by multiple sub-signals, which control the point state through "OR" or "AND" operations. When the remote signaling point to be measured is a merging point using an "OR" operation, the initial state is a separate state; when the remote signaling point to be measured is a merging point using an "AND" operation, the initial state is a combined state.
[0068] 3.2.1 The acceptance method for merging remote signaling point sub-signals using the "OR" operation includes:
[0069] 3.2.1.1 The acceptance device in the station sends a control signal to set the merge point to be tested to the separate position state.
[0070] Since all sub-signals at the merging point are ORed, when the merging point under test is in a quantile state, all sub-signals are in a quantile state.
[0071] 3.2.1.2. The automatic point-to-point system sends the merging and demerging commands for each sub-signal sequentially to the central control station's automatic point-to-point system. The automatic point-to-point system then determines whether each sub-signal has been verified correctly based on the received commands and the actual status changes of the merging points at the central control station.
[0072] Since the merging point is connected via an OR operation, the merging point is in a merged state as long as any one of the sub-signals is in a merged state. Therefore, during detection, all sub-signals are first set to a separate state, and correspondingly, the merging point is also in a separate state. Then, each sub-signal is sequentially set to a merged state to verify whether each sub-signal is correct.
[0073] Specifically, the method for determining whether the verification of each sub-signal is correct is as follows: the centralized control station acceptance system verifies the sub-signal by combining the actual state changes of the merge point under test: if the merge point under test merges first and then separates, the sub-signal verification is correct; if the merge point under test does not merge first and then separate, the sub-signal verification is incorrect.
[0074] 3.2.2 The acceptance methods for merging various sub-signals of remote signaling points using the "AND" operation include:
[0075] 3.3.2.1 The station-side automatic point-to-point device sends a command to the centralized control station acceptance system through the gateway to set the merged point of the AND operation to be tested to the merged state.
[0076] Since the sub-signals at the merging point are ANDed, when the merging point under test is in a sum state, all sub-signals are in a sum state.
[0077] 3.3.2.2. The automatic point-to-point system sends the separation and merging commands for each sub-signal sequentially to the central control station's automatic point-to-point system. The automatic point-to-point system then determines whether each sub-signal has been verified correctly based on the received commands and the actual status changes of the merging points at the central control station.
[0078] Since the sub-signals at the merging point are ANDed, the merging point is in a split state as long as one sub-signal is split. Therefore, during verification, all sub-signals are first set to the merged state, and correspondingly, the merging point is also in the merged state at this time.
[0079] Specifically, the method for determining whether the verification of each sub-signal is correct is as follows: the centralized control station acceptance system verifies the sub-signal by combining the actual state changes of the merge point under test: if the merge point under test separates first and then merges, the sub-signal to be verified is correct; if the merge point under test does not separate first and then merge, the sub-signal to be verified is incorrect.
[0080] 3.3 The detection method for communication interruption of all devices includes the following steps:
[0081] 3.3.1 The automatic point-to-point device interrupts communication with a certain device, causing the gateway to send a communication interruption signal to the central control station. The central control station compares the device that actually experienced the communication interruption with the device that experienced the communication interruption signal sent by the gateway. If the device in the interruption signal matches the device that actually experienced the communication interruption, proceed to step two. If they do not match, the remote signaling verification for the communication interruption of that device fails.
[0082] 3.3.2 The station-side automatic point-to-point device restores the device's access, causing the gateway to send a communication interruption recovery action to the central control master station. The central control master station determines whether the communication interrupted device has resumed communication; if communication has resumed, the communication interruption verification for that device is successful.
[0083] Step 4: Automatic Acceptance of Telemetry Signals
[0084] The station-side automatic point-to-point device sequentially sends acceptance data for each telemetry point to the centralized control station's acceptance system via the gateway to verify the telemetry points. In this embodiment, the acceptance data consists of the point number plus an offset, the magnitude of which needs to be determined with the centralized control master station. In this embodiment, the offset is set to 0.99. The acceptance data for telemetry point number 1 is 1.99, the acceptance data for telemetry point number 2 is 2.99, and so on.
[0085] During verification, the central control station verification system reconstructs the telemetry point number to be tested based on the received acceptance data, and compares the actual telemetry point number received from the acceptance data with the telemetry point number to be tested. If they match, the telemetry point number to be tested is verified as correct. The specific verification process is as follows: Figure 3 As shown.
[0086] Step 5: Automatic acceptance of remote control signals.
[0087] The methods for automatic acceptance of remote control signals include the following two:
[0088] 5.1 Individual acceptance method for remote control signals:
[0089] In this embodiment, to ensure the accuracy of the acceptance test, both the station-side monitoring backend and the central control master station need to send a merging command and a dismerging command to the acceptance device within the site, totaling two merging commands and two dismerging commands. To ensure that the two merging commands are not sent consecutively, thus affecting the accuracy of the acceptance test, in this embodiment, after the station-side monitoring backend sends the merging command, the central control master station acceptance system needs to send the dismerging command; and after the station-side monitoring backend sends the dismerging command, the central control master station acceptance system needs to send the merging command. For example... Figure 4 As shown, the specific method is as follows:
[0090] 5.1.1 The station-side automatic acceptance device sets the location of all remote control associated remote signaling points of the entire station as the unit;
[0091] 5.1.2 When the acceptance personnel click on the remote control preset and cancel preset of a certain device in the station monitoring background, the station automatic acceptance device will record the preset command after receiving it, automatically change the position of the relevant equipment, and send the remote signal point as the preset position.
[0092] 5.1.3 After receiving the remote signal indicating the change in position from the station monitoring backend, the acceptance personnel will conduct a manual comparison.
[0093] 5.1.4 After receiving the remote signal change, the automatic acceptance system of the new energy central control station automatically issues the remote control sub-preset command and cancel the preset for the corresponding equipment. The automatic acceptance device at the station end records the preset command after receiving it.
[0094] 5.1.5 When the acceptance personnel click on the remote control preset and cancel preset of a certain device in the station monitoring background, the automatic acceptance device at the station receives the preset command, records it, automatically changes the position of the relevant equipment, and sends the remote signal point as the preset position.
[0095] 5.1.6 After receiving the remote signal indicating the change in position, the acceptance personnel will manually compare it.
[0096] 5.1.7 After receiving the remote signal change, the automatic acceptance system of the new energy centralized control station automatically issues the remote control connection preset command and cancel preset command for the corresponding equipment. After receiving the remote control preset command, the automatic acceptance device at the station end automatically compares the remote control connection and disconnect preset commands of the station end monitoring background with those of the automatic acceptance system of the new energy centralized control station to see if they meet the expected judgment logic. If they meet the expected judgment logic, the corresponding remote control associated remote signal point is sent as the connection position. If they do not meet the expected judgment logic, the corresponding remote control associated remote signal point is sent as the connection position first and then disconnected.
[0097] 5.1.8 The automatic acceptance system for new energy central control stations determines that the remote control point has passed acceptance when it receives the final change of the remote signal to the closed position, and determines that the remote control point has failed acceptance when it receives the final change of the remote signal to the open position. It also supports one-click export of remote control acceptance results.
[0098] 5.2 Batch verification method for remote control signals:
[0099] The batch verification method for remote control signals can verify multiple remote control signal points at once. In this embodiment, the combined position of a batch of remote control signals is verified first, and then the individual positions of this batch of remote control signals are verified. If both the combined and individual positions of a single remote control point are verified correctly, it means that the remote control point has been verified correctly; otherwise, it means that the remote control point has been verified incorrectly. Figure 5 As shown, the specific acceptance steps in this embodiment are as follows:
[0100] 5.2.1 During remote control acceptance testing, the station-side automatic acceptance device sends the remote control associated remote signaling points of the entire station as the unit.
[0101] 5.2.2 The acceptance personnel shall send the equipment remote control presets and cancel presets in sequence on the station-end monitoring backend;
[0102] 5.2.3 The automatic acceptance system for new energy centralized control stations sends equipment remote control presets and cancel presets in the same order;
[0103] 5.2.4 The station-end automatic acceptance device automatically compares whether the remote control preset commands of the station-end monitoring backend and the new energy centralized control station automatic acceptance system are consistent. If they are consistent, the corresponding remote control associated remote signaling point is sent to the "closed" position. If they are inconsistent, the corresponding remote control associated remote signaling point is sent to the "closed" position first and then "separated" position. After the new energy centralized control station automatic acceptance system receives the remote signal and the final change to the "closed" position, it judges that the remote control "closed" acceptance has passed. After receiving the remote signal and the final change to the "separated" position, it judges that the remote control "closed" acceptance has failed.
[0104] 5.2.5. When conducting remote control acceptance testing, the process is the same, but the results are reversed. You can select 50 or 100 remote control signals as a group for batch acceptance, and it supports one-click export of remote control acceptance results.
[0105] Step Six: Generate acceptance reports for the signal points of the field station and central control station.
[0106] Generate and export telemetry, teleindication (including independent teleindication points and merged points), and remote control acceptance reports. The report content includes information such as site information, acceptance personnel information, acceptance time, acceptance type, number of passes, number of failures, and single-point acceptance details. The exported report is in PDF format and cannot be modified.
[0107] Example of an in-station acceptance device:
[0108] In this embodiment, the power station takes a new energy power station as an example. The acceptance device in the power station is an automatic pairing device that simulates the station-end device model of the new energy power station for pairing (therefore, it is also referred to as an automatic pairing device below). The automatic pairing device is physically isolated from the actual operating environment of the new energy power station. During the pairing process, the automatic pairing device simulates the actions of the equipment in the new energy power station. The corresponding equipment in the actual operating environment does not move, so pairing can be carried out without affecting the actual operation of the new energy power station.
[0109] The site acceptance device includes a processor, which performs the following steps when executing a computer program:
[0110] 1) After all the acceptance devices in the site have been verified to be correct, the acceptance devices in the site send control commands to the central control master station to make all remote signaling points of the central control master station in the initial state;
[0111] 2) The on-site acceptance device sends an acceptance instruction for the remote signaling point to be tested to the central control master station. The acceptance instruction includes a displacement instruction that puts the remote signaling point to be tested in a state opposite to its initial state. This allows the central control master station to determine the point number of the remote signaling point to be tested based on the received acceptance instruction, and to judge whether the actual change of the remote signaling point to be tested at the central control master station at that point number matches the displacement instruction in the acceptance instruction. If they match, the remote signaling point to be tested is accepted correctly; otherwise, the remote signaling point to be tested is accepted incorrectly.
[0112] The other functions of the acceptance device within the site have been described in detail in the method embodiment, and will not be repeated in this embodiment.
[0113] Example of a centralized control master station:
[0114] The central control master station includes a processor, which executes the following steps when running a computer program:
[0115] 1) After receiving the control command, the centralized control master station initializes all remote signaling points of the centralized control master station; the control command is sent from the field acceptance device to the centralized control master station after all field acceptance devices have verified that there are no errors.
[0116] 2) Determine the remote signaling point to be tested based on the received acceptance instruction; and determine whether the actual change of the remote signaling point to be tested in the central control master station is consistent with the acceptance instruction. If it is consistent, the remote signaling point to be tested is verified correctly; if it is not consistent, the remote signaling point to be tested is verified incorrectly. The acceptance instruction is sent by the acceptance device in the field to the central control master station, and the acceptance instruction includes a change instruction that makes the remote signaling point to be tested in a state opposite to its initial state.
[0117] The other functions of the centralized control station have been described in detail in the method embodiment, and will not be repeated in this embodiment.
[0118] In summary, the method for verifying signal points at a field station and a centralized control station, the field station verification device, and the centralized control station of the present invention, after verifying that the forwarding tables of the field station verification device and the gateway are correct, first reset all remote signaling points to their initial states, and then send verification instructions to the remote signaling points to be tested. The verification instructions include a change instruction that causes the remote signaling points to be tested to be in a state opposite to the initial state. The centralized control station verification system compares the received change instruction with the actual change of the remote signaling points to be tested. If the actual change matches the verification instruction, it indicates that the verification of the remote signaling points to be tested is correct; if it does not match, it indicates that the verification of the remote signaling points to be tested is incorrect. This method enables accurate point verification of remote signaling points and improves the verification effect.
[0119] Furthermore, the present invention can also perform acceptance testing on merged points in remote signaling locations, and select different initial states and set corresponding acceptance instructions according to the operation logic between the sub-signals of the merged point, thereby verifying each sub-signal of the merged point and improving the accuracy of remote signaling location verification.
