The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here.

[0029] As introduced in the background technology, due to the uneven equipment levels of the power distribution terminal encryption devices, the "pseudo-death" state is often encountered during the operation and maintenance of the power distribution terminal encryption devices, and the operation and maintenance personnel are required to go to the site to reset (re-power on) the power distribution terminal encryption devices. Since the power distribution terminal encryption devices are deployed together with the power distribution terminals (such as FTU) in outdoor environments such as outdoor ring network cabinets and overhead lines of distribution lines, the equipment deployment distribution shows a "sparse" feature. The cost of resetting the power distribution terminal encryption devices by the operation and maintenance personnel is high, resulting in low operation and maintenance efficiency. In order to solve the problem that the cost of resetting the power distribution terminal encryption devices by the operation and maintenance personnel in the existing solutions is high, resulting in low operation and maintenance efficiency, the embodiments of the present application provide a reset and status detection system, method, medium, product and electronic device for a power distribution terminal encryption device.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] The present application provides a reset and status detection system for a power distribution terminal encryption device, the system comprising:

[0032] A hardware reset module, wherein the hardware reset module comprises a timer circuit and a switch device, wherein the timer circuit is used to control the on-off state of the switch device to achieve power management of the power distribution terminal encryption device, thereby automatically performing a reset operation;

[0033] A serial port data detection unit, wherein the serial port data detection unit passively monitors the RS232 serial port of the power distribution terminal encryption device by means of physical wiring, and is used to detect data transmission of the serial port to determine the working status of the power distribution terminal encryption device;

[0034] The serial port data detection unit is connected to the hardware reset module, and determines whether to trigger the hardware reset module to reset the power distribution terminal encryption device according to the detected serial port data status.

[0035] In the above system, the serial port data detection unit is connected to the hardware reset module, and whether to trigger the hardware reset module to reset the distribution terminal encryption device is determined according to the detected serial port data status, so that the system can effectively prevent equipment stagnation caused by software failure or abnormality, ensure that the distribution terminal encryption device can automatically resume operation in an unattended power network environment, and improve the overall stability and response speed of the power system, thereby solving the problem of high cost of resetting the distribution terminal encryption device by operation and maintenance personnel in the existing solution, resulting in low operation and maintenance efficiency.

[0036] In one embodiment of the present application, the switch device is a relay or an electronic switch. The use of the electronic switch can not only reduce the volume and weight of the system, but also improve the accuracy and speed of the reset operation, and is suitable for high-load environments that require frequent reset operations, such as monitoring centers of large power facilities.

[0037] In one embodiment of the present application, the model of the encryption chip of the above-mentioned power distribution terminal encryption device is a model that meets the requirements of data encryption protection and two-way identity authentication. It ensures that the system can respond quickly to various abnormal situations, while supporting communication with external devices, facilitating remote monitoring and maintenance, and is suitable for remote monitoring and automated management scenarios of power networks. For example, the TEE chip, the TEE (Trusted Execution Environment) chip is a hardware environment for executing trusted code and protecting sensitive data, usually integrated in mobile devices, IoT devices, etc., to provide secure data storage and communication functions.

[0038] In one embodiment of the present application, the serial port data detection unit includes a serial port conversion and protection circuit for isolating and protecting data signals.

[0039] The serial port conversion and protection circuit can realize the function of serial port data detection. The specific implementation method is as follows:

[0040] Serial port conversion: First, the serial port signal needs to be converted into a level signal suitable for processing. Generally speaking, the serial port signal is a TTL level signal (0-5V), while the microcontroller or other devices may need to use a different level signal. Therefore, a conversion chip (such as MAX232) can be used to convert the serial port signal into an RS232 level signal or other required level signal.

[0041] Serial port protection: In the process of converting levels, it is necessary to protect the serial port signal from external interference or damage. You can use components such as resistors, capacitors, and TVS tubes to protect the serial port signal to prevent the influence of electrostatic discharge, electromagnetic interference, etc. on the serial port signal.

[0042] Data detection: In the conversion and protection circuit, a data detection circuit can be added to detect the transmission of serial port data. For example, the integrity of the data can be verified by detecting the data bit, check bit and other information, or the baud rate, start bit and other information can be detected to confirm whether the data transmission is normal.

[0043] In one embodiment of the present application, the system further includes a dog feeding signal detection module, and the watchdog configuration message receiving and decoding module detected by the dog feeding signal detection module identifies and processes the configuration message through data receiving and decoding to control the opening or closing of the watchdog function. This enables the system to dynamically adjust the watchdog function according to actual needs, which is suitable for flexible management of the operating status of equipment in the power network.

[0044] In one embodiment of the present application, the system further includes a dog feeding signal detection module, which is implemented using a corresponding logic circuit or software algorithm and is used to monitor the state of the dog feeding signal in real time. When the dog feeding signal is abnormal for a set time, a reset operation is triggered. The real-time monitoring mechanism can quickly identify equipment failures and reduce fault recovery time, and is suitable for scenarios in power networks that have high requirements for equipment failure response speed.

[0045] To detect the dog feeding signal, you can use a logic circuit or a software algorithm. The following are two methods:

[0046] Logic circuit implementation:

[0047] Digital logic circuits can be used to detect the dog feeding signal. A common method is to use a counter to count the frequency of the dog feeding signal. If the dog feeding signal is not received for more than a certain time interval, it is considered that the system has failed. Logic elements such as gate circuits and triggers can be used to implement this function.

[0048] Software algorithm implementation:

[0049] It is also a common method to use the software of a single-chip microcomputer or embedded system to detect the dog feeding signal. The status of the dog feeding signal can be monitored by writing a timer interrupt program. If the dog feeding signal is not received for a certain period of time, the corresponding fault handling program is triggered. The timeout time of the dog feeding signal can be defined in the software algorithm and adjusted according to the actual situation.

[0050] The RS232 serial port uses ADM3251EARWZ, which has the function of isolating input and output data signals, and uses air discharge tubes GDT1, GDT2, GDT3, thermistors PPTC1, PPTC2 and transient suppression diodes (TVS-SMBJ12CA) D4, D5, D6 on the data line, which can effectively suppress external interference to the system.

[0051] The reset and status detection system of the power distribution terminal encryption device includes a watchdog configuration message receiving module for receiving watchdog configuration messages, a watchdog configuration message decoding module for decoding the watchdog configuration message, a watchdog reset generator for sending a reset signal, and a dog feeding signal detection module for detecting a dog feeding signal, wherein the watchdog configuration message receiving module is a one-way communication mode; the watchdog configuration message decoding module sends a command to turn on or off the watchdog function to the watchdog reset generator; the watchdog configuration message receiving module and the watchdog configuration message decoding module receive and decode the watchdog configuration message using the method of steps S1 to S6. The watchdog reset generator 4 is provided with a watchdog status register, a counter, a reset signal module 7 and a power-on reset register 8. The dog feeding signal detection module is provided with a status register and a signal detection submodule.

[0052] Specific steps:

[0053] Step S0, start;

[0054] Step S1, receiving a watchdog configuration message, including converting the configuration message into parallel data, and identifying the data in the watchdog configuration message by a maximum likelihood decision method;

[0055] Step S2, decoding of watchdog configuration message data, specifically including S3 to S6;

[0056] Step S3, determining whether the watchdog configuration message data in step S2 is a frame start bit, if yes, proceeding to step S4; if no, continuing to determine whether the watchdog configuration message data in step S2 is a frame start bit;

[0057] Step S4, storing the watchdog configuration message data, storing the watchdog configuration message in a register;

[0058] Step S5, determining whether the data in the storage process of step S4 is a frame end bit; it should be noted that steps S4 and S5 are not sequential, that is, it is possible to first determine whether it is a frame end bit, and then store the watchdog configuration message data;

[0059] Step S6, determining whether the data in the watchdog configuration message of the current frame corresponds to a command for disabling the watchdog function;

[0060] Step S7, if step S6 parses that there is no command to turn off the watchdog function in the current frame watchdog configuration message, execute to turn on the watchdog function; otherwise, execute S8;

[0061] Step S8, turning off the watchdog function;

[0062] Step S9, determining whether the dog feeding signal meets the reset condition, if yes, executing step S10, if no, continuing to detect and determine whether the dog feeding signal meets the reset condition;

[0063] Step S10, sending a reset signal to the relay.

[0064] A first register and a second register are set in the dog feeding signal detection module, the value in the first register lags behind the dog feeding signal by one clock, and the value in the second register lags behind the first register by one clock; if it is detected at the same time that the value in the first register and the value in the second register are different, the counter in the reset signal generator starts timing.

[0065] After the counter in the reset signal generator starts timing, the timing time of the counter in the reset signal generator is determined; if the time meets the watchdog change time, the status register in the feeding signal detection module is set to the watchdog signal is in a normal state; if the time does not meet the watchdog change time, the status register in the feeding signal detection module is set to the watchdog signal is in an abnormal state. Considering that the general master station call cycle is 15 minutes, the reset time of the reset timer is designed to be 30 minutes.

[0066] The reset signal output is connected to the relay, and the watchdog configuration message input is monitored by the serial port.

[0067] The specific principle of the reset and status detection system of the power distribution terminal encryption device is as follows Figure 1 As shown, I will not elaborate on it here.

[0071] Step S202, passively monitoring the RS232 serial port of the power distribution terminal encryption device by physical wiring, detecting the data transmission of the serial port, and determining the working state of the power distribution terminal encryption device;

[0072] Step S203: The serial port data detection unit is used to determine whether to trigger the hardware reset module to perform a reset operation according to the detected serial port data state.
