DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] In one embodiment, if Figure 1 As shown, the present application discloses a method for reducing transmission loss of a distributed communication system, which specifically includes the following steps: S10: Acquire types of multiple expansion modules and corresponding module configuration information in the distributed communication system, wherein the expansion modules are connected to a local programmable high-speed backplane communication chip via a high-speed differential communication interface.

[0026] Specifically, the local programmable high-speed backplane communication chip first communicates with multiple expansion modules in sequence through a high-speed differential communication interface. Each expansion module has independent identification information and configuration parameters. The local programmable high-speed backplane communication chip will scan all connected expansion modules, obtain their type, number of input bytes, number of output bytes, communication protocol mode and other configuration information, and store this information in its internal designated storage unit so that it can be quickly called and used in subsequent communication processes.

[0027] S20: Establishing a communication connection through a parallel communication interface between the local programmable high-speed backplane communication chip and the main control chip.

[0028] Specifically, the main control chip sends an initialization signal to the local programmable high-speed backplane communication chip through its output interface, triggering the chip to enter a communication ready state, and configuring the address lines and data lines one by one to ensure that they can accurately and synchronously transmit addresses and data. Among them, the local programmable high-speed backplane communication chip and the main control chip establish a two-way communication channel through a parallel communication interface, and use a clock synchronization mechanism for preliminary testing to ensure that the communication connection can correctly support high-speed data transmission.

[0029] Furthermore, in the case of 32 expansion modules, when the main control chip starts the communication operation, 15 address lines are activated, each address line is responsible for transmitting the bit information of a specific address, and the local programmable high-speed backplane communication chip receives the expansion module address information from the main control chip through these address lines, and compares it with the previously stored module configuration information to ensure that the data is sent to the correct module. Among them, the address line avoids address transmission errors through the verification mechanism of the hardware logic circuit, and triggers the retransmission mechanism when an unmatched address is detected. The 15 address lines are based on the optimal selection of the addressing space under 32 expansion modules, providing 2 15 =32768 address units; During the data transmission phase, 16 data lines are used in parallel, and each line transmits one bit of data synchronously under the control of the clock signal. When the data is sent from the main control chip, the local programmable high-speed backplane communication chip receives the complete 16-bit data packet through these data lines and immediately processes the data packet in the next clock cycle. In order to ensure the stability of data transmission, the system calibrates the signal level of the data line before data transmission to reduce data errors caused by electromagnetic interference or signal noise.

[0030] S30: Acquire the clock signal of the main control chip, and based on the clock signal, control the local programmable high-speed backplane communication chip to perform data reading and writing operations.

[0031] Specifically, the clock signal generated by the main control chip is transmitted to the local programmable high-speed backplane communication chip through the parallel communication interface. After receiving the clock signal, the chip synchronizes the clock signal through the internal clock trigger to ensure that each time point of the data reading and writing operation is consistent with the rising or falling edge of the clock. The clock signal not only controls the direction of data flow, but also ensures the stability of the order and rate of data transmission.

[0032] S40: Transmitting data to the plurality of expansion modules in sequence according to the configuration information of the expansion modules, and updating the expansion module status information in the internal storage unit after each transmission is completed, so as to reduce the delay in data transmission.

[0033] Specifically, the local programmable high-speed backplane communication chip selects the target expansion modules one by one according to the configuration information of the expansion modules, reads the input or output byte number of each module, and transmits data according to its communication mode. During the data transmission process, the local programmable high-speed backplane communication chip controls the sending of data packets according to the rising edge of the current clock signal to ensure that the data can be transmitted to the designated module efficiently and accurately. After each data transmission is completed, the storage unit inside the chip will record the status changes of the current module, including the number of bytes completed, whether the transmission is successful or not, and other information, in order to adjust the subsequent data transmission logic.

[0034] In one embodiment, if Figure 2 As shown, in step S30, based on the clock signal, the local programmable high-speed backplane communication chip is controlled to perform data reading and writing operations, specifically including: S31: When the read enable signal of the master chip is at a low level and the write enable signal is at a high level, data is read from the internal storage unit of the local programmable high-speed backplane communication chip, and the data is transmitted to the master chip through the parallel communication interface.

[0035] Specifically, when the local programmable high-speed backplane communication chip detects that the read enable signal is at a low level, the chip will read the corresponding 16-bit data from the internal storage unit. At this time, the write enable signal is kept at a high level to ensure that the data will not be overwritten. The chip packages the read data through the parallel communication interface and transmits it to the main control chip in sequence. The data transmission process is triggered by the rising edge of the clock signal to ensure that each data packet can be sent on time and accurately arrive at the receiving port of the main control chip.

[0036] S32: When the read enable signal of the master control chip is at a high level and the write enable signal is at a low level, the data received from the master control chip is written into the internal storage unit of the local programmable high-speed backplane communication chip.

[0037] Specifically, when the main control chip sets the read enable signal to a high level and the write enable signal to a low level, the backplane communication chip enters the write mode and receives data sent from the main control chip. The main control chip will transmit 16-bit data through the parallel communication interface. The backplane communication chip receives the data according to the timing and stores it in the internal storage unit to ensure that the data will not be lost or damaged during the transmission process, and the write operation can be completed smoothly under the control of a stable clock signal.

[0038] In one embodiment, if Figure 3 As shown, in step S31, data is read from the internal storage unit of the local programmable high-speed backplane communication chip, and the data is transmitted to the main control chip through the parallel communication interface, which specifically includes: S311: The local programmable high-speed backplane communication chip reads the specified 16-bit data from the internal storage unit through the parallel communication interface.

[0039] Specifically, when data needs to be read from the storage unit of the backplane communication chip, the communication chip obtains 16-bit data from the storage unit through the parallel communication interface. The reading process is synchronously controlled by the clock signal. The backplane chip reads the data at the specified address in the storage unit according to the rising or falling edge of the clock signal. These data can be control information or status information, ensuring that the data can be read accurately and quickly.

[0040] S312: The local programmable high-speed backplane communication chip sends the 16-bit data to the main control chip through the parallel communication interface, and triggers the sending action at the rising edge of the clock signal of the main control chip.

[0041] Specifically, the read 16-bit data is transmitted to the main control chip through the parallel communication interface of the backplane communication chip, and the timing of transmission is determined by the rising edge of the clock signal of the main control chip. When the rising edge of the clock signal arrives, the backplane communication chip triggers the data sending action to ensure the synchronization of data transmission and avoid data transmission errors caused by timing disorders.

[0042] In one embodiment, if Figure 4 As shown, in step S32, the data received from the main control chip is written into the internal storage unit of the local programmable high-speed backplane communication chip, which specifically includes: S321: The local programmable high-speed backplane communication chip receives data from the main control chip through the parallel communication interface.

[0043] Specifically, when the main control chip needs to send data to the local programmable high-speed backplane communication chip, the main control chip sends data to the backplane chip through the parallel communication interface. These data can be control commands, configuration information or other transmission data. The data is transmitted through a 16-bit wide data bus, and the transmission process is controlled by the clock signal of the main control chip to ensure the synchronization and consistency of the data.

[0044] S322: Write the received data into the internal storage unit of the local programmable high-speed backplane communication chip. The write operation is triggered based on the rising edge of the clock signal of the main control chip to ensure the consistency and stability of the data.

[0045] Specifically, the received 16-bit data will be written to the internal storage unit of the backplane communication chip according to the control of the clock signal. The write operation is usually triggered by the rising edge of the clock to ensure that the data can be stored in the correct timing, avoid timing errors or losses in data transmission, and ensure data stability and consistency.

[0046] In one embodiment, after step S40, that is, after updating the expansion module status information in the internal storage unit after each transmission is completed, the following further includes: S50: Reconfigure the configuration information of the expansion module to adapt to subsequent data transmission.

[0047] Specifically, during the data transmission process, if the configuration of some expansion modules changes, or the working mode of the module needs to be readjusted according to the new transmission requirements, the configuration information of the expansion module needs to be reconfigured. The reconfiguration of the module is usually achieved by sending control commands. This process may include changing the data transmission rate, data format or communication protocol to ensure the correct transmission of data.

[0048] In one embodiment, if Figure 5 As shown, in step S50, the configuration information of the expansion module is reconfigured, specifically including: S51: Send a configuration command to the expansion module via the local programmable high-speed backplane communication chip, and update the configuration register setting of the expansion module according to the configuration command.

[0049] Specifically, the backplane communication chip sends configuration commands to the expansion module through the parallel communication interface. The configuration commands can specify the module's operating mode, communication rate, etc. After receiving the command, the expansion module will update its configuration register according to the command to ensure that the module can work according to the new configuration, thereby adapting to subsequent data transmission requirements.

[0050] S52: Acquire update feedback information of the expansion module, and verify whether the configuration information of the expansion module is updated successfully according to the update feedback information, so as to ensure the stability and consistency of data transmission.

[0051] Specifically, after receiving the configuration command, the expansion module will inform the backplane communication chip through feedback information whether the configuration update has been successfully completed. The feedback information may include the value of the status register, confirmation signal, etc. The backplane communication chip determines whether the configuration of the expansion module has been successfully updated based on this feedback information. If the update fails, it may be necessary to resend the configuration command for adjustment to ensure stability and consistency during data transmission.

[0052] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
