[0002] In the substation system, the remote control of the distribution automation terminal is an important functional component of the monitoring system. The circuit breakers, disconnectors, gears, and even protective pressure plates in the substation can be remotely controlled.

[0040] In the substation system, the remote control of the distribution automation terminal is an important functional component of the monitoring system. The circuit breakers, disconnectors, gears, and even protective pressure plates in the substation can be remotely controlled. When the telemetry and telesignaling data of the substation are abnormal, the impact is not great, but abnormal remote control operation will directly affect the safe and stable operation of the power grid. In the worst case, it will cause the remote control to refuse to operate and delay the power outage; in the worst case, it will cause the remote control to malfunction and cause the accident of misclosing. Therefore, when powering on and off the automation terminal equipment, it is necessary to avoid the uncertainty and fluctuation of the remote control output, which will cause the subsequent actuators to jump randomly, and ensure the stability and reliability of the remote control output from the source.

[0041] To this end, the embodiments of the present invention propose a remote control malfunction output protection circuit, method, electronic device and storage medium. By connecting the first control signal output terminal of the first bus transceiver to a pull-down resistor, all output ports of the second bus transceiver can be in a high-impedance state, that is, an isolated state, during power-on, and the current output signal will not be changed. Therefore, before the state of each remote control pin is confirmed, the original state on site will not be changed, thereby avoiding malfunction of the remote control.

[0042] On the one hand, if Figure 1As shown, the remote control malfunction output protection circuit according to the embodiment of the present invention includes a main control module 100, a first bus transceiver 200, an inverting module 300 and a second bus transceiver 400, the main control module 100 has a plurality of first signal input terminals and a plurality of first signal output terminals, the first signal input terminals and the first signal output terminals correspond to each other one by one, and the first signal input terminals are electrically connected to the main control module 100; the first bus transceiver 200 also has a first control signal input terminal and a corresponding first control signal output terminal, the first control signal input terminal is electrically connected to the main control module 100, and the first control signal input terminal is connected to a pull-down resistor; the inverting module 300 0 is electrically connected to the first control signal output terminal; the second bus transceiver has multiple second signal input terminals and multiple second signal output terminals, the second signal input terminals correspond to the second signal output terminals and the first signal output terminals one by one, each second signal input terminal is electrically connected to the corresponding first signal output terminal, and each second signal output terminal is used to output a remote control signal; the second bus transceiver also has a second control signal input terminal, and the second control signal input terminal is electrically connected to the output terminal of the inverting module 300; wherein, when the first control signal input terminal is at a low level, the second control signal input terminal is at a high level, and each second signal output terminal is in a high impedance state.

[0043] Specifically, the main control module 100 is used to control the output of the remote control signal and the operating state of the entire system. In this example, the main control module 100 includes a CPU, and the first bus transceiver 200 and the second bus transceiver 400 are controlled by the CPU.

[0044] like Figure 2 As shown, in this example, the first bus transceiver 200 uses a bidirectional bus transceiver chip U44 of model SN74LVC16245. Figure 2It can be seen that the first bus transceiver 200 has a plurality of first signal input terminals, which are 1A0~1A7 and 2A0-2A5 of the chip U44, respectively. 1A0~1A7 and 2A0-2A5 of the chip U44 are connected to KOUT0~KOUT13 in sequence. KOUT0~KOUT13 is used as a remote control output signal and is connected to the main control module 100 to receive the remote control output signal issued by the main control module 100. Correspondingly, the first bus transceiver 200 also has a plurality of first signal output terminals, which are 1B0-1B7 and 2B0~2B5 of the chip U44, respectively. 1B0-1B7, 2B0~2B5 of U44 correspond to 1A0~1A7, 2A0-2A5 of U44 one by one. When the first bus transceiver 200 receives the remote control signal issued by the main control module 100 through the first signal input terminal, it can send it to the second bus transceiver 400 through the first signal output terminal. At the same time, the first bus transceiver 200 also has a first control signal input terminal and a corresponding first control signal output terminal. In this example, the first bus transceiver 200 has two first control signal input terminals and two first control signal output terminals. The two first control signal input terminals are 2A6 and 2A7, respectively, which are respectively connected to the KOUT_EN0 and KOUT_EN1 signals issued by the main control module 100. The two first control signal output terminals are 2B6 and 2B7, respectively, which are used to output KOUT_EN0_1 and KOUT_EN1_1 signals according to the KOUT_EN0 and KOUT_EN1 signals, and send the KOUT_EN0_1 and KOUT_EN1_1 signals to the inverting module 300.

[0045] like Figure 2 As shown, in this example, the second bus transceiver 400 also uses a bidirectional bus transceiver chip U45 of model SN74LVC16245. Figure 2 It can be seen that the second bus transceiver 400 has a plurality of second signal input terminals, which are 1A0-1A7 and 2A0-2A5 of the chip U45, respectively. The 1A0-1A7 and 2A0-2A5 of the chip U45 are sequentially connected to the 1B0-1B7 and 2B0-2B5 of the chip U44, so as to receive the signal sent by the first bus transceiver 200. Correspondingly, the second bus transceiver 400 also has a plurality of second signal output terminals, which are 1B0-1B7 and 2B0-2B5 of the chip U45, respectively. The 1B0-1B7, 2B0-2B5 of the chip U45 correspond to 1A0-1A7, 2A0-2A5 one by one. When the second bus transceiver 400 receives the remote control signal sent by the first bus transceiver 200, it can send the remote control signal to the back end through DO0-DO13. Meanwhile, the second bus transceiver 200 also has a second control signal input terminal. In this example, the second bus transceiver 400 has two second control signal input terminals, and the two second control signal input terminals are respectively and When the first control signal output terminal sends the KOUT_EN0_1 and KOUT_EN1_1 signals to the inverting module 300, the inverting module 300 inverts the KOUT_EN0_1 and KOUT_EN1_1 signals and outputs the KOUTEN0 and KOUTEN1 signals to the and A pull-up resistor is also connected between each first signal output terminal and each second signal input terminal.

[0046] It should be noted that the first bus transceiver 200 and the second bus transceiver 400 may also adopt other types of bus transceiver chips, but are not limited thereto.

[0047] The inversion module 300 is used to invert the KOUT_EN0_1 and KOUT_EN1_1 signals and output the inverted signals KOUTEN0 and KOUTEN1 to the second bus transceiver. When KOUT_EN0_1 and KOUT_EN1_1 are low, KOUTEN0 and KOUTEN1 are high; when KOUT_EN0_1 and KOUT_EN1_1 are high, KOUTEN0 and KOUTEN1 are low.

[0048] Specifically, Figure 3 As shown, in this example, since the number of the first control signal input terminal and the first control signal output terminal are both 2, correspondingly, the inverting module 300 includes a first inverter U46A and a second inverter U46C, the input terminal of the first inverter U46A is electrically connected to one of the first control signal output terminals (i.e., the 2B6 pin of the chip U44), and the output terminal of the first inverter U46A is electrically connected to one of the second control signal input terminals (i.e., the 2B6 pin of the chip U45). The input end of the second inverter U46C is electrically connected to another first control signal output end (i.e., the 2B7 pin of the chip U44), and the output end of the second inverter U46C is electrically connected to another second control signal input end (i.e., the 2B8 pin of the chip U45). At the same time, the input end of the first inverter U46A is also grounded through a resistor R30, and a first resistor R32 is connected between the output end of the first inverter U46A and one of the second control signal input ends, and the first resistor R32 is also connected to a power supply (+3.3V) through a second resistor R34; the input end of the second inverter U46C is grounded through a resistor R31, and a third resistor R33 is connected between the output end of the second inverter U46C and another second control signal input end, and the third resistor R33 is also connected to a power supply (+3.3V) through a fourth resistor R35.

[0049] The working principle of the remote control malfunction output protection circuit according to the embodiment of the present invention is as follows:

[0050] When the power distribution automation terminal is powered on, since all IO ports are in IO function and in input state when the CPU is powered on, KOUT0~KOUT13, KOUT_EN0, and KOUT_EN1 of U44 are directly from the CPU pins, so they are also in input state. KOUT_EN0 and KOUT_EN1 are in low level state because they are connected to pull-down resistors, and the outputs KOUT_EN0_1 and KOUT_EN1_1 are also in low level state. After being inverted by U46, the signals KOUTEN0 and KOUTEN1 are in high level state and applied to U45. and After that, the B-end DO0~DO13 of U45 is in a high-impedance state, that is, the circuit is disconnected, which has no effect on the subsequent control circuit, and will not cause the action of the subsequent control circuit, and will not affect the remote control state on site.

[0051] When the system software starts, uboot boots, and the port is initialized, the CPU pins KOUT_EN0 and KOUT_EN1 must be set as output pins, the output voltage is low, KOUTEN0 and KOUTEN1 are high, and DO0~DO13 are kept in a high impedance state. Load the kernel to initialize the port, and when running the kernel, ensure that these two pins are initialized as outputs and low.

[0052] After loading the file system, when running the application, set the high and low levels of DO0~DO13 according to the system configuration and the requirements of the automated terminal site. Finally, control KOUT_EN0 and KOUT_EN1 to a high level, turn on the output of U45, and complete the output of the remote control signal.

[0053] The pull-down setting of R30 and R31 also ensures that KOUTEN0 and KOUTEN1 are high level during the entire power-on moment, making the circuit more stable and reliable. KOUT0~KOUT13 are remote control output signals. The IO port output function must also be set when the uboot and kernel are initialized, but the output state must be set in the application.

[0054] Since U45 is divided into two groups, 1An-1Bn and 2An-2Bn, they can be used separately. and to control.

[0055] In addition, in some embodiments of the present invention, the remote control malfunction output protection circuit further includes an adjustable power supply module, which is electrically connected to the second bus transceiver 400 and is used to provide a variety of different power supplies for the second bus transceiver. That is, the output voltage of U45 is adjustable, and the voltage of VCCB is generally 5V and 3.3V to meet the needs of the remote control output board.

[0056] On the other hand, based on the remote control malfunction output protection circuit described in the above-mentioned embodiment, the embodiment of the present invention also proposes a remote control malfunction output protection method, such as Figure 4 As shown, the method comprises the following steps:

[0057] Step S100: After the main control module 100 is powered on, the port is initialized and the first control signal input terminal is set as an output pin;

[0058] Step S200: the first control signal output terminal outputs a low-level first control signal to the inverting module;

[0059] Step S300: the inversion module 300 inverts the first control signal to generate a high-level second control signal, and sends the second control signal to the second control signal input terminal, so that the second signal output terminal maintains a high-impedance state;

[0060] Step S400: When the main control module 100 runs the application, it outputs a first remote control signal to the first bus transceiver 200 according to the system configuration and the terminal site requirements;

[0061] Step S500: the first bus transceiver 200 configures the high and low level states of each second signal output terminal of the second bus transceiver 400 according to the first remote control signal;

[0062] Step S600: the main control module 100 controls the first control signal input terminal to be at a high level, the second control signal input terminal to be at a low level, and the second signal output terminal to output a second remote control signal.

[0063] Specifically, when the distribution automation terminal is powered on, the main control module 100 is powered on, and all IO ports are in IO function and in input state. KOUT0~KOUT13, KOUT_EN0, and KOUT_EN1 of U44 are directly from the CPU pins, so they are also in input state. KOUT_EN0 and KOUT_EN1 are in a low level state because they are connected to pull-down resistors, so the first control signal output end also outputs a low-level first control signal, that is, outputs low-level KOUT_EN0_1 and KOUT_EN1_1. After the first control signal is inverted by U46, the inverting module 300 generates a high-level second control signal KOUTEN0, KOUTEN1, and the high-level second control signal is applied to U45 and After that, the second signal output terminal (that is, the B terminal DO0~DO13 of U45 is in a high-impedance state), that is, it is in a circuit-disconnected state, which has no effect on the subsequent control circuit, and will not cause the action of the subsequent control circuit, and will not affect the remote control state on site.

[0064] After the file system is loaded, when the main control module 100 runs the application, it sets the high and low levels of DO0~DO13 according to the system configuration and the requirements of the automated terminal site, and finally controls KOUT_EN0 and KOUT_EN1 to a high level, turns on the output of U45, and completes the output of the remote control signal.

[0065] The pull-down setting of R30 and R31 also ensures that KOUTEN0 and KOUTEN1 are high level during the entire power-on moment, making the circuit more stable and reliable. KOUT0~KOUT13 are remote control output signals. The IO port output function must also be set when the uboot and kernel are initialized, but the output state must be set in the application.

[0066] Since U45 is divided into two groups, 1An-1Bn and 2An-2Bn, they can be used separately. and to control.

[0067] In addition, in some embodiments of the present invention, the remote control malfunction output protection circuit further includes an adjustable power supply module, which is electrically connected to the second bus transceiver 400 and is used to provide a variety of different power supplies for the second bus transceiver. That is, the output voltage of U45 is adjustable, and the voltage of VCCB is generally 5V and 3.3V to meet the needs of the remote control output board.

[0068] According to the remote control malfunction output protection circuit and method of the embodiment of the present invention, by connecting the first control signal output terminal of the first bus transceiver 200 to a pull-down resistor, it is possible to make all output ports of the second bus transceiver 400 in a high-impedance state, that is, an isolated state, when the device is powered on, and the current output signal will not be changed. Therefore, before the state of each remote control pin is confirmed, the original state of the scene will not be changed, thereby avoiding malfunction of the remote control.

[0069] Since the VCCA and VCCB of the 74LVCH16T245 device can be powered at any voltage between 1.2V and 5.5V, the device is suitable for conversion between any low-voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V), eliminating the need for level conversion devices. Since U45 uses 74LVCH16T245, the IO port is in input characteristics and the pull-down resistor is locked from the hardware through the CPU power-on. and , making it a high level, ensuring that the remote control output port is in a high-impedance state when powered on, avoiding uncertainty in the remote control state during the software system booting period when the distribution automation terminal is powered on.

[0070] The unique Ioff of 74LVCH16T245 makes this circuit fully suitable for applications with partial power-off to achieve power-off isolation. The Ioff circuit disables the output to prevent any harmful backflow current flowing through the circuit when the power is off. In suspend mode, when VCCA or VCCB is at GND level, both the nAn port and the nBn port are in high impedance state, thus avoiding the introduction of remote control false action when the device is powered off.

[0071] On the other hand, an embodiment of the present invention further provides an electronic device, including:

[0072] A memory for storing program instructions;

[0073] The processor is used to call the program instructions stored in the memory and execute the remote control malfunction output protection method described in the embodiment of the present invention according to the obtained program instructions.

[0074] On the other hand, an embodiment of the present invention further provides a storage medium storing computer executable instructions, wherein the computer executable instructions are used to enable a computer to execute the remote control malfunction output protection method described in the embodiment of the present invention.

In addition, the memory may include a high-speed random access memory, and may also include a non-transient memory, such as at least one disk storage device, a flash memory device, or other non-transient solid-state storage devices.
