[0019] Among them, D input is the input modulation signal, θ is the modulation phase, and T is the time window during demodulation;

[0020] The demodulated bit stream is then formatted into a standard data packet structure and transmitted to the wireless debugging command parsing module.

Under the control of the control command sent by the debugging software, it is retrieved in sequence along the path opposite to the aforementioned path, and finally displayed on the debugging software, completing the debugging of the chip.

[0025] Another object of the present invention is to provide a distribution network relay protection system based on a power-specific chip, which can monitor the power grid status in real time, quickly detect and isolate faults in the power grid, protect the safe and stable operation of the power grid, and prevent the expansion of faults.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Example 1, reference Figure 1 , which is the first embodiment of the present invention, and provides a distribution network relay protection method based on a power-specific chip, comprising:

[0046] S1: Select a chip that matches the power distribution terminal and install it in the power distribution terminal. Install a debugging device in the power distribution terminal and use debugging software to debug the software running on the chip.

[0047] Furthermore, a debugging device is installed in the power distribution terminal, and debugging software is used on the debugging device to debug the software running on the chip. The debugging device includes an underlying network protocol driver module. The chip is installed on a circuit board and includes a wireless protocol controller, a wireless debugging command parsing module, a JTAG command and read data cache, and a CPU. When the chip runs the debugging command, it performs a write operation and / or a read operation on the debugging object;

[0048] After performing the read operation on the debug object, the chip feeds back the read data to the debug device and receives confirmation information from the debug device; and when the confirmation information is failure information, the chip resends the read data to the debug device until the confirmation information is success information;

[0049] It should be noted that debugging of the software running on the chip includes single-step execution, inserting or deleting breakpoints, setting watch points and changing data values. There is no longer a position restriction between the debugging device and the circuit board, and wireless LAN debugging or Internet remote debugging can be used. Debugging chips no longer require simulation debuggers and download cables, and multiple chips can be debugged at the same time. After replacing or upgrading the CPU, only the debugging software needs to be replaced or upgraded when debugging is required. It is very convenient to debug multiple debugging targets in the LAN or on the Internet at the same time. The operating frequency of the JTAG interface can be greatly increased, and the data transmission speed is faster.

[0050] It should also be noted that the debugging device includes an underlying network protocol driver module, the chip installed on the circuit board includes a wireless protocol controller, a wireless debugging command parsing module, a JTAG command and read data cache, and a CPU, and the chip performs write operations and / or read operations on the debugging object when running the debugging command;

[0051] After performing the read operation on the debug object, the chip feeds back the read data to the debug device and receives confirmation information from the debug device. When the confirmation information is failure information, the chip resends the read data to the debug device until the confirmation information is success information.

[0052] The underlying network protocol driver module includes the following wireless protocols: Wifi, Bluetooth, NB-IoT and Zigbee.

[0053] S2: The debugging software sends the debugging commands and data to the operating system. According to the selected path, the operating system converts the debugging commands into wireless signals and sends them to the circuit board.

[0054] Furthermore, the debugging software generates a debugging command, which includes information such as execution instructions, target address, data, and checksum.

[0055] Each command is formatted as a data packet, and the data packet structure is defined as follows:

[0056] Header: contains the packet start identifier, packet length, and type information;

[0057] Payload: contains specific debugging commands and parameters;

[0058] Checksum: used for subsequent data integrity verification.

[0059] The debugging software selects the appropriate wireless communication protocol based on the characteristics of the target board and environmental conditions;

[0060] Adaptive waveform coding suitable for wireless transmission is used to optimize data transmission in different signal-to-noise ratio environments. Each data packet is encoded before sending, and the data is transmitted to the circuit board through the interface of the network protocol stack, the underlying protocol driver of the debugging device, and the encapsulation and encryption of the data packet.

[0061] It should be noted that Hamming coding is used for error correction, and redundant bits are added to each data packet to detect and correct bit errors:

[0062]

[0063] Among them, d H is the Hamming distance, x i represents the i-th bit in the bit string x, y i is the i-th bit in the bit string y, and n represents the length of the bit string.

[0064] When using Hamming coding, errors can be located and corrected by analyzing the Hamming distance. H If the value is less than or equal to a certain threshold, it means that only a small number of errors have occurred and can be corrected by redundant bits; if it is greater than this threshold, it cannot be corrected and re-encoding is required.

[0065] S3: The circuit board receives the wireless signal and transmits the wireless signal to the wireless protocol controller in the chip.

[0066] Furthermore, the circuit board captures scattered and reflected wireless signals through antennas, and the weak signals received are amplified by low-noise amplifiers to improve the signal-to-noise ratio;

[0067] After the amplified signal is modulated and demodulated by the demodulation circuit, it is necessary to identify the data packet in the signal, detect the starting mark of the data packet by setting the packet header recognition algorithm, perform data integrity detection on the extracted data packet, and use the improved CRC cyclic redundancy check algorithm to increase the fixed value to improve the correction capability of burst errors:

[0068]

[0069] Among them, CRC n Represents the cyclic redundancy check value, d i represents the value of the i-th data bit, P i represents the bit weight, C frepresents the redundant bits introduced under specific conditions, k represents the total number of bits in the data stream, and mod represents the modulus operation;

[0070] After verification, the data packet is sent to the wireless protocol controller to extract the debugging command and corresponding parameters.

[0071] S4: The wireless protocol controller is configured in a debugging mode, converts the received wireless signal into received data and sends the received data to the wireless debugging command parsing module.

[0072] Furthermore, after receiving the signal, a preliminary signal capture is performed to analyze the received RF signal transmission quality and signal-to-noise ratio to evaluate whether the signal meets the processing conditions. The signal quality analysis uses the following formula to determine whether the signal enters the debug mode:

[0073] SNR threshold =SNR current -L noise

[0074] Among them, L noise is the ambient noise level, SNR current Indicates the current signal-to-noise ratio, SNR threshold Indicates the signal-to-noise ratio threshold. current When the signal is greater than the set threshold, it will be further processed.

[0075] After confirming that the signal quality is qualified, the wireless protocol controller automatically switches to the debugging mode. The activation of the debugging mode will also trigger the demodulation process of the signal to ensure that the subsequent processing enters a specific decoding process;

[0076] The improved digital demodulation algorithm is used to demodulate the received modulated signal and extract the data bit stream. When setting the signal to be modulated, frequency shift keying or phase keying is used. The demodulation process accurately extracts each bit. The demodulated bit stream is expressed as:

[0077] D output =f(D input ,θ,T)

[0078] Among them, D input is the input modulation signal, θ is the modulation phase, and T is the time window during demodulation;

[0079] The demodulated bit stream is then formatted into a standard data packet structure and transmitted to the wireless debugging command parsing module.

[0080] Furthermore, the received wireless signal is converted into received data and sent to the wireless debugging command parsing module;

[0081] The module receives data and converts it into commands and data that comply with the JTAG protocol. According to the operating frequency and data transmission speed of the JTAG interface of the CPU, the commands and data that comply with the JTAG protocol obtained by the wireless debugging command parsing module are cached in the JTAG command and read data cache.

[0082] It should be noted that the JTAG command and the commands and data in the read data cache are sent to the JTAG interface of the CPU in the original order, and the debugging device uses wireless LAN debugging or Internet remote debugging;

[0083] When the debugging software needs to read the data and status in the chip, it first sends the corresponding read command and necessary data information according to the aforementioned path. After the JTAG interface finally receives the read command, it sends the data to the JTAG command and read data cache. Under the control of the control command sent by the debugging software, it is retrieved in sequence along the path opposite to the aforementioned path, and finally displayed on the debugging software, completing the debugging of the chip.
