As shown in fig. 1, according to an aspect of the present invention, there is provided a superconducting maglev train electromagnetic propulsion system high-speed communication method, including: the control core of the electromagnetic propulsion system signal processor synchronously shares data of each control cycle of the electromagnetic propulsion system to the communication core of the electromagnetic propulsion system signal processor; the communication core sequentially presses data of each control cycle into any one of the two buffer areas of the communication core, after a certain amount of data is pressed into the buffer area, the data of the buffer area is sent in batch through the Ethernet card, and the data of the next control cycle is pressed into the other buffer area of the two buffer areas of the communication core, so that the two buffer areas of the communication core are alternately used for data storage and sending to complete high-speed communication of the superconducting maglev train electromagnetic propulsion system.

By applying the configuration mode, the high-speed communication method of the superconducting magnetic levitation train electromagnetic propulsion system is provided, the high-speed communication method of the superconducting magnetic levitation train electromagnetic propulsion system realizes the high-speed communication of the superconducting magnetic levitation train electromagnetic propulsion system by alternately pressing the data of each control period generated by the control core into the two buffer areas of the communication core and sending the data in each buffer area in batches by adopting the Ethernet card, and the data communication method can fully utilize the performance of the Ethernet card and realize the high-speed, large-capacity and timely communication of the data. Compared with the prior art, the technical scheme of the invention can solve the technical problem that the communication method of the electromagnetic propulsion system in the prior art cannot meet the requirements of high-speed, large-capacity and real-time communication.

Further, in the present invention, in order to implement high-speed communication of the superconducting maglev train electromagnetic propulsion system, first, the control core of the electromagnetic propulsion system signal processor synchronously shares data of each control cycle of the electromagnetic propulsion system to the communication core of the electromagnetic propulsion system signal processor. As an embodiment of the present invention, the electromagnetic propulsion system may employ a dual-core digital signal processor, such as TMS320F28379D, and implement data synchronization by sharing a memory between CPU1 and CPU2, wherein CPU1 is used as a control core to execute a control program, and CPU2 is used as a communication core to communicate with the outside. Data at N detection points in the CPU1 need to be communicated for detection, and the shared memory data CPU2 updates the data at the corresponding N detection points in real time. The dual-core digital signal processor can realize the isolation and parallel execution of a control program and a communication program so as to ensure the reliability and the real-time performance of the electromagnetic propulsion system.

In addition, in the invention, after the communication core synchronously acquires the data of the control core, the communication core sequentially pushes the data of each control cycle into any one of the two buffer areas of the communication core, after a certain amount of data is pushed into the buffer area, the data of the buffer area is sent in batch through the Ethernet card, and the data of the next control cycle is pushed into the other buffer area of the two buffer areas of the communication core, so that the two buffer areas of the communication core are alternately used for data storage and sending to complete the high-speed communication of the superconducting maglev train electromagnetic propulsion system.

As a specific embodiment of the invention, the high-speed communication method of the electromagnetic propulsion system of the superconducting maglev train specifically comprises the following steps.

And the communication core receives the data of the current control period of the control core. In the invention, the data of each control period received by the communication core is judged according to the high-speed communication method of the invention.

And judging whether the buffer count of the communication core is greater than the buffer count threshold value. In the present invention, the buffer count threshold may be set according to actual requirements, for example, the buffer count threshold may be set to 200.

If the buffer area count is larger than or equal to the buffer area count threshold value, the buffer area count is updated to be zero and the Ethernet card is triggered to transmit, and whether the current data pressing buffer area is the first buffer area or not is judged. In the invention, two data buffers are arranged in a communication core, and the size of each buffer is set to be N.M, wherein N is the number of detection points in a control core, and M is a buffer counting threshold value. In addition, as shown in fig. 1, a CacheFlag variable may be established to identify a buffer to which the current data is pushed, and indicate that the current data is pushed into the buffer as a first buffer when CacheFlag is equal to True, and indicate that the current data is pushed into the buffer as a second buffer when CacheFlag is equal to True.

And if the current data push buffer area is the first buffer area, the Ethernet card sends the data of the first buffer area and switches the identifiers of the first buffer area and the second buffer area. In the present invention, the data can be transmitted via CacheFlag! The CacheFlag switches the identities of the first buffer and the second buffer. Judging whether the current data pressing buffer area is a first buffer area, if so, pressing the data of the current control period into a second buffer area, and adding one to the count of the buffer area; and if the current data pressing buffer area is not the first buffer area, pressing the data of the current control period into the first buffer area, and adding one to the count of the buffer area. In this embodiment, for example, if the current data push buffer is the first buffer, the ethernet card sends the data in the first buffer, and switches the identifiers of the first buffer and the second buffer, and if the current data push buffer is changed to the second buffer, the data in the current control cycle is pushed into the new first buffer, and the buffer count is incremented by one.

If the current data press-in buffer area is not the first buffer area, the Ethernet card sends the data of the second buffer area and switches the identifiers of the first buffer area and the second buffer area, whether the current data press-in buffer area is the first buffer area or not is judged, if the current data press-in buffer area is the first buffer area, the data of the current control period is pressed into the second buffer area, and the count of the buffer area is increased by one; and if the current data pressing buffer area is not the first buffer area, pressing the data of the current control period into the first buffer area, and adding one to the count of the buffer area. In this embodiment, for example, if the current data push buffer is the second buffer, the ethernet card sends the data in the second buffer, and switches the identifiers of the first buffer and the second buffer, and if the current data push buffer is changed to the first buffer, the data in the current control period is pushed into the new second buffer, and the buffer count is incremented by one.

If the buffer area count is smaller than the buffer area count threshold value, judging whether the current data pressing buffer area is a first buffer area, if the current data pressing buffer area is the first buffer area, pressing the data of the current control period into a second buffer area, and adding one to the buffer area count; and if the current data pressing buffer area is not the first buffer area, pressing the data of the current control period into the first buffer area, and adding one to the count of the buffer area. In this embodiment, for example, if the current data push buffer is the first buffer, then the data for the current control cycle is pushed into the second buffer and the buffer count is incremented by one.

And the communication core receives the data of the control core in the next control period and returns to judge whether the buffer counting of the communication core is greater than the buffer counting threshold value.

In the invention, the method of pressing and sending data by combining the Ethernet card with the buffer area is adopted, the acquisition of the data of each control period of the control core is realized, the electromagnetic propulsion system only needs to add the Ethernet card chip, such as W5500, on the control panel, compared with the conventional method, the method reduces the number of sensors and extra detection equipment, replaces the method of acquiring the operation data by adopting an oscilloscope or a wave recorder, and greatly reduces the communication cost of the electromagnetic propulsion system. By adopting the high-speed communication method of the superconducting maglev train electromagnetic propulsion system, the first buffer area and the second buffer area of the communication core can be used for communication transmission and data pressing at the same time, the first buffer area and the second buffer area are not influenced by each other, and the performance of the Ethernet card is fully utilized. After the buffer counting threshold is set, the pressure of Ethernet card communication can be reduced, and the communication efficiency can be improved by centralized and unified sending processing. By the technology, the high-speed real-time detection of the operation control data of the electromagnetic propulsion system can be realized, and the fault diagnosis and prediction can be realized more quickly.

Therefore, the high-speed communication method of the superconducting maglev train electromagnetic propulsion system is applied to the superconducting maglev train electromagnetic propulsion system, and the working performance of the superconducting maglev train electromagnetic propulsion system can be greatly improved.

Further, in the present invention, in order to achieve high speed communication for a superconducting maglev train electromagnetic propulsion system, a configurable electromagnetic propulsion system comprises: an electromagnetic propulsion system signal processor and an ethernet card. The electromagnetic propulsion system signal processor comprises a control core and a communication core, wherein the control core is used for executing a control program of the superconducting magnetic levitation train electromagnetic propulsion system and generating data of each control cycle; the communication core is connected with the control core and used for synchronously receiving the data of each control cycle of the control core and sequentially and alternately pressing the data of each control cycle into the first buffer area and the second buffer area of the communication core. The Ethernet card is connected with the communication core and used for sending data of the first buffer area or the second buffer area of the communication core in batches so as to realize high-speed communication of the electromagnetic propulsion system of the superconducting maglev train.

As an embodiment of the present invention, the ethernet card may be connected to the communication core through a Serial Peripheral Interface (SPI).

In addition, in the invention, in order to further compress the data volume of communication, the communication protocol of the data of the first buffer area and the second buffer area of the configurable communication core is consistent with the communication protocol of the data sent by the Ethernet card in batch.

As a specific embodiment of the present invention, the communication protocol includes a start code, a data amount, a data sampling period, clock information, the number of samples, and each sample data. In the invention, the data packet is identified by adopting the start code and the data volume, thereby being beneficial to a receiver to process the data. The data volume is the byte length of the data packet, the clock information is the sampling time of the first data in the data packet, the sampling number is the number N of detection points in the control core, N data are pressed in each control cycle, and the specific communication protocol is as shown in table 1 below.

TABLE 1 communication protocol

The start code is used for dividing a data packet when the Ethernet card data is pasted with the packet, and is set to be FF FF. And the clock information is set as the current time service time with the precision us. The data sampling period is a control period, and the time precision is us. The data amount is the number of data contained in the data packet. The data are arranged in sequence according to each control cycle of the detection points. The receiver can calculate the sampling specific time of each data through the data packet starting time and the data sampling period, so that the storage of clock information is reduced.
