[0065] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a fusion terminal controller, etc. that can implement the above functions. The following takes the fusion terminal controller as an example to illustrate this embodiment and the following embodiments.

[0066] It should be understood that the fusion terminal mentioned in this embodiment and the following embodiments is an intelligent device in the power system, mainly used for the automation and intelligent management of the distribution network. It deeply integrates and fuses the functions of traditional primary equipment (such as high-voltage electrical equipment like switches and transformers) and secondary equipment (such as protection devices, measurement and control devices, communication equipment, etc.), thereby realizing real-time monitoring, control, and protection of the operating state of the distribution network.

[0067] Structurally, it mainly consists of a sealed waterproof machine box, a panel, a storage battery, an FT3 electrical port, a collection pulse terminal board assembly, a control board assembly, etc. The device is designed with an inverted installation method in terms of structure. The wiring terminals are installed on the machine box surface, and the terminal circuit board is supported and fixed on the panel by welding to the wiring posts. The control board is installed in a stacked manner with copper posts below the terminal board, and the electrical signal connection between the two is carried out by means of pin insertion.

[0068] Functionally, the digital fusion terminal at least includes a logic control module and a digital signal generation module, and the logic control module and the digital signal generation module are connected in sequence. Specifically, the logic control module at least includes a pulse signal acquisition module and a control module, and the pulse signal acquisition module and the control module are connected. The pulse signal acquisition module is mainly used to receive the output voltage pulse signals of various distribution fusion terminals, so as to generate corresponding feedback signals to achieve the automation test of the distribution automation feeder.

[0069] In this embodiment, the pulse input signals mainly include a closing input signal and an opening input signal. Since this embodiment mainly focuses on the control of the digital distribution fusion terminal, in the specific execution process, the fields of the preset digital message frame are filled according to different pulse input signals.

[0070] Among them, the preset digital message frame at least includes at least one of the following fields:

[0091]

[0092]

[0093] In one embodiment, the pulse input signal includes a trip signal, a close signal, a stored energy position signal, and a low air pressure interlock signal;

[0097] Filling the stored energy position signal into the seventh bit of the second status field in the preset digital message frame;

[0098] Filling the low air pressure interlock signal into the eighth bit of the second status field in the preset digital message frame.

[0099] In a specific implementation, the trip signal, the close signal, the stored energy position signal, and the low air pressure interlock signal are strictly filled into the corresponding bits of the second status field, so as to ensure the integrity of the message data and improve the rate of network data synchronization.

[0100] In a specific implementation, refer to Figure 2 , Figure 2This is an implementation mode of the CPLD circuit in this embodiment. Among them, the CPLD circuit mainly consists of an FT3 optical port, an FT3 electrical port, a CPLD control module, and a JTAG interface. The FT3 optical port is responsible for converting electrical signals into optical signals and transmitting them through optical fibers; the FT3 electrical port is responsible for receiving the optical signals transmitted from the optical fibers and converting them back into electrical signals; the CPLD (Complex Programmable Logic Device) is used to implement complex logic functions, including signal processing, data transmission control, etc. The JTAG interface is used to debug and program programmable devices (such as CPLDs) on the circuit board.

[0101] Receive a pulse input signal through the logic control module, including receiving a pulse input optical signal through the FT3 optical port, and converting the pulse input optical signal into a pulse input electrical signal and transmitting it to the CPLD control module for decoding to obtain a pulse input signal.

[0102] Since analog pulse signals cannot be directly read by the CPLD chip, the pulse input signal needs to be decoded and converted into binary data to improve the subsequent data processing and message filling efficiency.

[0103] The process of sending the FT3 message to the distribution terminal is to convert the FT3 message digital electrical signal into an optical signal through the drive circuit of the FT3 optical port. The optical signal is transmitted through the optical fiber to the receiving end of the distribution terminal. At the receiving end, the optical signal is converted back into an electrical signal through the receiving circuit of the FT3 electrical port, so as to decode the FT3 message and execute the corresponding program.

[0104] In one embodiment, the method for verifying the operating state of the distribution terminal further includes:

[0105] When the type of the distribution terminal is an electromagnetic or electronic distribution fusion terminal, generate a distribution terminal opening / closing position signal through the pulse input signal;

[0106] Send the distribution terminal opening / closing position signal to the distribution terminal.

[0107] In a specific implementation, if the type of the distribution terminal is an electromagnetic or electronic distribution fusion terminal, then control the opening / closing state of the relay by collecting the input pulse signal of the distribution terminal, and output it to the distribution terminal opening / closing position signal through the cable connection interface to achieve the opening or closing control of the distribution terminal, so as to achieve the compatible control of electromagnetic, electronic, and digital distribution fusion terminals and improve the control adaptability of different types of distribution fusion terminals.

[0108] In this embodiment, the logic control module receives a pulse input signal; a FT3 message is generated by the digital signal generation module according to the pulse input signal and a preset digital message framework; the FT3 message is sent to the power distribution terminal through the CPLD circuit, and the received pulse input signal is combined with the preset digital message framework by the digital signal generation module to generate a digital FT3 message signal, so as to accurately detect whether the power distribution terminal performs a tripping operation or a closing operation, be compatible with the status detection of different types of power distribution integration terminals, and avoid the technical problems of poor compatibility and additional costs when the integration terminal in the prior art detects the operating status of multiple types of power distribution terminals.

[0109] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as that in the above-mentioned first embodiment can be referred to the above introduction and will not be repeated hereinafter.

[0110] Step S101: Receive a pulse input optical signal through the pulse signal acquisition module, and convert the pulse input optical signal into a pulse input electrical signal and transmit it to the control module.

[0111] Step S102: Obtain the time stamp of each frame of pulse input optical signal received by the pulse signal acquisition module.

[0112] Step S103: Determine the signal transmission frequency according to the time stamp.

[0113] Step S104: Decode the pulse input electrical signal according to the signal transmission frequency to obtain a pulse input signal.

[0114] It should be understood that when the FT3 optical port of the CPLD circuit receives a pulse input optical signal, the pulse input optical signal is converted into a pulse input electrical signal and transmitted to the CPLD control module for decoding to obtain a pulse input electrical signal, and it is input to the control module. In order to improve the subsequent message filling efficiency and data processing efficiency, it is also necessary to decode the transmitted analog electrical signal.

[0115] In one embodiment, the decoding the pulse input electrical signal according to the signal transmission frequency to obtain a pulse input signal includes:

[0116] Determine the Manchester code rate according to the signal transmission frequency;

[0117] Determine the pulse input signal division period based on the Manchester code rate;

[0118] Statistically analyze the change trend of the signal within each signal division period;

[0119] Assign periods to each signal according to the change trend for value assignment, so as to decode the pulse input electrical signal and obtain a binary input signal.

[0120] Reference Figure 4 , Figure 4 is the specific decoding schematic diagram of this embodiment. For a signal division period, if the signal within this period changes from high level to low level, it corresponds to binary 0. On the contrary, if the signal within this period changes from low level to high level, it corresponds to binary 1, and finally a digital binary input signal is formed.

[0121] In this embodiment, the Manchester code rate is determined according to the signal transmission frequency; the pulse input signal division period is determined based on the Manchester code rate; the change trend of the signal within each signal division period is counted; periods are assigned to each signal division period according to the change trend to decode the pulse input electrical signal and obtain a binary pulse input signal, and the optical signal received by the receiver is decoded to obtain a binary input signal, improving the efficiency of subsequent generation of FT3 messages.
