[0028] With the continuous development of power systems, relay protection technology plays a vital role in ensuring the safety and stable operation of power equipment. Traditional power relay protection experiments mostly use a method of directly connecting to high-voltage power supplies and high-current equipment. Although this experimental mode allows experimenters to intuitively understand the basic principles of relay protection, it also has many shortcomings.
[0029] First, since they are in direct contact with high-voltage power, the experimenters will face the risk of electric shock and equipment damage during the experiment; secondly, the experimental equipment lacks a wiring verification mechanism, making it difficult to determine whether the experimenters have connected the wires correctly.
[0030] For example, when conducting relay protection experiments in student laboratories, although the existing technology introduces the sampled value (SV) transmission mechanism in the IEC61860 standard to prevent students from having dangerous contact, there is still a lack of effective means to verify whether the students' wiring is correct during actual operations.
[0031] In this regard, the present application provides a safe wiring verification method that can be applied to an electric power experiment system. Figure 1 A system structure diagram of an electric power experiment system provided for an embodiment of the present application, as shown in the figure, the electric power experiment system includes a relay protection module 101, a wiring panel 102 and a control unit 103, and the control unit 103 can be used to execute the safety wiring verification method of the present application. It can be imagined that the control unit 103 can be a processor, and the processor may include an application processor (application processor, AP), a central processing unit (central processing unit, CPU) and other processing units to process data.
[0032] It is understandable that before the experiment begins, the experimenter uses connecting wires such as wires to connect the relay protection module 101 and the wiring panel 102 according to the experimental wiring requirements, but the process is prone to the experimenter not being able to clearly understand the experimental wiring requirements and making incorrect connections, and then when the experiment begins, it is easy for the experimenter to get an electric shock or equipment damage. In this regard, this solution can verify the wiring situation of the experimenter to determine whether there is a wrong wiring situation. It is conceivable that after the formal experiment completes the safety wiring verification, the experiment can be started by outputting a corresponding signal after the verification is completed to indicate that the current wiring is correct and the experiment can be started, and the experimenter manually starts the experiment; of course, it can also be actively started by the device when the verification is completed and the wiring is determined to be correct, such as opening the corresponding path so that the signal used in the experiment can be connected to the power experiment system. It is conceivable that the pulse signal output by the relay protection module 101 can be formed based on a weak power supply, and isolated from the high voltage used in the experiment, so that it will not be interfered by the high voltage when the wiring verification is performed.
[0033] In the electric power experiment system, the relay protection module 101 is connected to the wiring panel 102, and the wiring panel 102 is also connected to the control unit 103. The relay protection module 101 is provided with a plurality of pulse output terminals, and the relay protection module 101 is used to output different pulse signals through the plurality of pulse output terminals thereon. For example, in some embodiments, the pulse widths corresponding to the pulse signals provided by the pulse output terminals are different; optionally, in one embodiment, the pulse amplitudes corresponding to the pulse signals provided by the pulse output terminals are different. The wiring panel 102 includes a plurality of pulse access terminals. Optionally, in one embodiment, the wiring panel 102 includes a plurality of pulse access terminals corresponding to the number of pulse output terminals.
[0034] When the pulse output terminal is connected to the pulse access terminal through a connecting line, the connection panel 102 accesses the corresponding pulse signal through the pulse access terminal. It can be understood that the pulse signals output by different pulse output terminals are different, such as the pulse emission time, pulse width and other pulse parameters are inconsistent. In the power test system, the time difference of the pulse signal from the pulse output terminal to the pulse access terminal is small, and the access time of this pulse is equivalent to the pulse emission time.
[0035] After the experimenter completes the wiring, the control unit 103 in the power experiment system can verify the wiring through the pulse signals received by each pulse access terminal on the wiring panel 102. The specific steps are as follows: Figure 2 As shown, Figure 2 A schematic diagram of the steps of a safety wiring verification method provided in an embodiment of the present application, the method comprising steps S110-S130:
[0036] Step S110: When it is determined that at least one pulse input terminal on the wiring panel is connected to the pulse output terminal, a pulse signal input by the wiring panel through the pulse input terminal is obtained, and a pulse parameter of the pulse signal is determined.
[0037] It is understandable that the wiring panel is also provided with a plurality of pulse access terminals, and the number of the pulse access terminals is the same as the number of the pulse output terminals. Therefore, the wiring situation of the experimenter is complicated, such as connecting the pulse output terminal to the pulse access terminal in a one-to-one correspondence, connecting the pulse output terminal to the pulse access terminal in a many-to-one manner, etc. In this regard, when the experimenter completes the wiring, the pulse output terminal on the relay protection module outputs a pulse signal, and the wiring panel receives the corresponding pulse signal through the pulse access terminal thereon. The control unit can monitor the pulse signals received at each port to obtain the pulse parameters of the pulse signal.
[0038] It should be noted that the pulse signal can be the output of the relay protection module controlled by the experimenter after completing the wiring, or the control unit can send a corresponding control signal through the connecting line between the wiring panel and the relay protection module to trigger the output of the relay protection module.
[0039] The pulse parameters include access time and pulse width. In one embodiment, during the access of the pulse signal, the control unit may monitor the pulse signal through the pulse access terminal to determine the corresponding pulse parameters. The specific steps are as follows S111-S113:
[0040] Step S111: In response to each pulse access terminal receiving a pulse signal, record an access time corresponding to the pulse signal.
[0041] Step S112: Determine the pulse width of the pulse signal based on the measurement of the pulse signal.
[0042] Step S113: Use the access time and pulse width as pulse parameters and associate them with the pulse access end of the access pulse signal.
[0043] It can be understood that the pulse signals outputted from each pulse output terminal are different in time and pulse width, such as Figure 3 As shown, Figure 3 A waveform diagram of a pulse signal provided for an embodiment of the present application, taking four pulse output ports as an example, ports 1 to 4 are connected in sequence to emit pulse signals as shown in the figure, for example, port 1 generates a pulse signal with a pulse width of 5 ms at 5 ms, port 2 generates a pulse signal with a pulse width of 10 ms at 15 ms, port 3 generates a pulse signal with a pulse width of 15 ms at 30 ms, and port 4 generates a pulse signal with a pulse width of 20 ms at 50 ms.
[0044] It should be noted that when there are 2, 3 or more pulse output terminals, the above-mentioned manner can be used for analogy and expansion. It is conceivable that the output of the corresponding pulse signal for each pulse output terminal is preset, such as outputting the corresponding pulse signal through a pulse signal generator.
[0045] In this regard, the access time of the pulse signal can be recorded by pulse scanning, and the duration of the pulse signal at a high level can be recorded, so as to determine the pulse width of the pulse signal to achieve measurement of the pulse signal, and then determine the pulse parameters corresponding to each pulse signal. When recording the pulse parameters, the control unit associates the pulse parameters with the pulse access terminal that accesses the pulse signal. Optionally, in one embodiment, the pulse parameters are recorded as data and the data is associated with the corresponding pulse access terminal by setting a data tag, an identification field, etc., so as to record the pulse parameters of the pulse signal accessed by each pulse access terminal.
[0046] Therefore, by configuring different pulse signals at each pulse output terminal, after completing the wiring, the pulse signals connected to each pulse access terminal are scanned and detected. The control unit can determine the corresponding pulse parameters and can quickly judge the current wiring status, which is helpful for safe wiring verification.
[0047] Step S120: determining the port status of the wiring panel based on the pulse parameters, wherein the port status is associated with the pulse signal received by each pulse access terminal.
[0048] It can be imagined that the pulse signals corresponding to each pulse output terminal are different. The control unit can determine the pulse signal connected to each pulse access terminal and its corresponding pulse output terminal based on the pulse signal connected to the pulse access terminal, such as based on the waveform of the connected pulse signal, and then determine the port status of the wiring panel, that is, it can determine the pulse output terminal connected to each pulse access terminal on the wiring panel for wiring verification.
[0049] Step S130: Determine whether there is a target port with incorrect wiring in the current pulse access terminal according to the port status and the target port status corresponding to each pulse access terminal.
[0050] The target port status corresponds to the pulse output terminal to which each pulse access terminal is connected when the wiring is correct, that is, the control unit can record the correct wiring situation, so that after the experimenter completes the wiring, the control unit can determine the pulse output terminal to which the current pulse access terminal is connected by detecting the port status, and then by comparing the current wiring situation with the correct wiring situation, the control unit can determine whether there is a target port with incorrect wiring in the current pulse access terminal, so as to determine that the experimenter has made a wiring error when there is a target port with incorrect wiring.
[0051] Optionally, in one embodiment, when it is determined that there is a target port with a wiring error in the current pulse access terminal, the control unit sends an alarm signal to the wiring panel to make the wiring panel suspend receiving the signal provided by the relay protection module. That is, when the wiring error occurs, the control unit outputs a corresponding alarm signal to inform the experimenter that the current wiring is wrong, and makes the wiring panel suspend receiving the signal provided by the relay protection module, so that the experimenter cannot perform the next experiment, thereby avoiding the experimenter from being electrocuted and the equipment being damaged due to the wrong wiring.
[0052] It can be seen from the above scheme that this scheme detects the wiring situation by setting different pulse signals to be transmitted between the pulse output end and the pulse access end, and compares the currently connected pulse signal and the correctly connected pulse signal corresponding to each pulse access end to complete the verification of the wiring situation. In this regard, this scheme provides an effective wiring verification mechanism, which can accurately judge whether there is a wrong wiring situation based on the pulse signal, thereby helping to reduce the risk of electric shock to experimenters and damage to equipment.
[0053] Figure 4 A schematic diagram of the steps for determining port parameters provided in an embodiment of the present application is shown in the figure. In one embodiment, for the port status of the wiring panel, the control unit represents it through a corresponding code value parameter, and the code value parameter is associated with the pulse signal, that is, different pulse signals correspond to different code values. The specific steps include steps S210-S220:
[0054] Step S210: Determine the waveform of the pulse signal currently accessed by each pulse access terminal according to the pulse parameters.
[0055] Step S220: According to the waveform of the pulse signal currently connected to the pulse access terminal, code value parameters corresponding to the currently connected pulse signal are configured for each pulse access terminal respectively to determine the port status of the wiring panel.
[0056] It can be understood that the control unit detects the pulse signals connected to each pulse access terminal on the wiring panel, and after determining the pulse parameters of the pulse signal, the waveform of the pulse signal currently connected to each pulse access terminal can also be determined accordingly. Optionally, for pulse signals of different waveforms, the control unit can represent them in binary code as their corresponding code values. It can be imagined that since the pulse signals output by each pulse output terminal are different, a unique corresponding code value can be configured for each pulse signal according to a preset coding rule, so that the control unit can quickly determine the currently connected pulse signal through the code value.
[0057] Optionally, in one embodiment, a plurality of pulse output terminals respectively output pulse signals of different widths, and different coding values are preconfigured for each pulse signal. When the control unit determines the waveform of the pulse signal currently connected to each pulse access terminal, the code value parameter corresponding to each pulse access terminal is determined accordingly according to the preconfigured coding value. For example, referring to Figure 3 For pulse signals of different waveforms, when a pulse access terminal only receives a pulse signal output by port 1, the code value 0001 can be used to represent the currently received pulse signal. Therefore, according to the corresponding code value, the pulse signal received by each pulse access terminal can be determined, thereby determining the pulse signals received by all pulse access terminals, and completing the identification of the port status.
[0058] The pulse signals accessed by each pulse access port are identified by code value parameters to determine the port status. The control unit can accurately learn the wiring status of each pulse access port, and can also quickly and accurately verify the safe wiring by comparing the code value parameters, which is conducive to improving the flexibility of wiring verification.
[0059] The wiring situation is complicated, such as connecting the pulse output terminal to the pulse access terminal in a one-to-one correspondence manner, connecting the pulse output terminal to the pulse access terminal in a many-to-one manner, etc. In this regard, in one embodiment, for each pulse access terminal, the control unit determines the coding value corresponding to each pulse signal in each of the pulse access terminals according to the waveform of the currently accessed pulse signal. In the case where the current pulse access terminal accesses a pulse signal, that is, the pulse access terminal is only connected to one pulse output terminal, the control unit uses the coding value corresponding to the accessed pulse signal as the code value parameter corresponding to the pulse access terminal.
[0060] In the case where the current pulse access terminal accesses multiple pulse signals, that is, the pulse access terminal is connected to multiple pulse output terminals, the control unit re-determines the code value based on the coding values corresponding to the multiple pulse signals accessed, and uses the code value as the code value parameter corresponding to the pulse access terminal. It can be understood that in the case where multiple pulse signals access the same pulse access terminal, after determining the pulse signal accessed by the pulse access terminal, the control unit can re-determine the code value corresponding to the pulse access terminal in accordance with the coding rules for each pulse signal, such as using code value superposition, code value subtraction, etc., which matches the preset coding rules, and then use it as the code value parameter corresponding to the pulse access terminal. In this regard, after determining the code value parameters corresponding to all pulse access terminals, the control unit determines the port status of the wiring panel according to the code value parameters corresponding to all pulse access terminals, such as arranging the corresponding code value parameters in the order of the pulse access terminals as the current port status of the wiring panel.
[0061] In one embodiment, the number of bits of the code value of the pulse signal is associated with the number of pulse output terminals, and each bit of the code value corresponds to the pulse output state of different pulse output terminals according to the setting order of the pulse output terminals, and the number of bits of the code value is the same as the number of bits of the code value. Figure 3 The pulse signal corresponding to the output of port 1 can be represented by the coding value 0001, the pulse signal corresponding to the output of port 2 can be represented by the coding value 0010, the pulse signal corresponding to the output of port 3 can be represented by the coding value 0100, and the pulse signal corresponding to the output of port 4 can be represented by the coding value 1000.
[0062] In this regard, when there is a pulse access terminal that is connected to multiple pulse signals, the control unit updates the value at the position corresponding to the code value according to the coding values corresponding to the multiple pulse signals that are connected, so as to redefine the value of the code value at each bit. Exemplarily, when a pulse access terminal is connected to the pulse signals output from port 1 and port 2, the coding value corresponding to the pulse signal output from port 1 is 0001, and the coding value corresponding to the pulse signal output from port 2 is 0010. In this regard, the values at the third and fourth bits of the code value are updated, and the redetermined code value is 0011. Accordingly, the code value is used as the code value parameter corresponding to the pulse access terminal. It can be imagined that if the pulse access terminal only connects to one pulse signal, such as connecting to Figure 3 For the pulse signal output by port 1, the code value 0001 can be used as the code value parameter corresponding to the pulse access end.
[0063] Therefore, the number of bits of the coding value of the pulse signal is associated with the number of pulse output terminals. The control unit can accurately represent the pulse output terminals connected to each pulse access terminal through the code value parameters corresponding to each pulse access terminal, and when the pulse signal connected to the pulse access terminal changes, the change of the pulse signal can be represented by updating the value at the corresponding position, thereby being able to flexibly adapt to complex wiring conditions and helping to quickly and accurately complete wiring verification.
[0064] In one embodiment, the port state is associated with a code value parameter, and the target port state corresponding to the pulse access terminal is associated with a preset code value. It is conceivable that the preset code value and the above-mentioned code value parameter are based on the same coding rule. Exemplarily, taking 4 pulse output terminals as an example, the wiring panel is provided with four pulse access terminals ad. The correct wiring situation is that port 1 is only connected to port a, port 2 is only connected to port b, port 3 is only connected to port c, and port 4 is only connected to port d. In this regard, the coding value of the corresponding pulse signal can be used as the preset code value corresponding to each pulse access terminal in the target port state. Therefore, when determining whether there is a target port with a wiring error, such as Figure 5 As shown, Figure 5 A schematic diagram of the steps for determining a target port provided in an embodiment of the present application, the control unit may adopt the following steps:
[0065] Step S310: Determine a preset code value associated with the target port state and a code value parameter associated with the port state.
[0066] Step S320: compare the code value parameter with the preset code value bit by bit.
[0067] Step S330: If the code value parameter is different from the preset code value, it is determined that there is a target port with a wrong wiring in the current pulse access terminal.
[0068] Step S340: If the code value parameter is the same as the preset code value, it is determined that there is no target port with a wrong wiring connection in the current pulse access terminal.
[0069] It can be understood that, according to the preset code value associated with the configured target port state, the code value parameter associated with the acquired port state is compared with it, such as comparing the code value parameter and the preset code value bit by bit. Referring to the above example, for port a, the correct wiring situation is that port 1 is connected to port a, and accordingly, the preset code value is 0001. If the code value parameter corresponding to port a in the acquired port state is 0011, it can be determined by bit by bit comparison that there is a difference between the code value parameter and the preset code value, and it can be determined that there is a target port with incorrect wiring in the current pulse access terminal, that is, port a is connected to other ports in addition to port 1, and an incorrect wiring situation occurs.
[0070] Of course, if the code value parameter corresponding to port a in the acquired port status is 0001, it can be determined by bit-by-bit comparison that the code value parameter is the same as the preset code value, and it is determined that there is no target port with incorrect wiring in the current pulse access terminal, that is, port a is only connected to port 1, and port a is correctly wired. Furthermore, similarly, by performing corresponding code value comparisons on other pulse access terminals with reference to the above scheme, the wiring conditions of all pulse access terminals can be determined, thereby completing the wiring verification. Therefore, through code value comparison, the control unit can efficiently and accurately detect whether there is an incorrect wiring situation, thereby effectively improving the efficiency and accuracy of wiring verification, and helping to reduce the risk of electric shock to experimenters and equipment damage.
