Embodiment 1

[0038] The output of the digital temperature acquisition probe adopts the form of simplex asynchronous Manchester code, and the output data adopts the form of single-line and one-way to send the collected temperature data to the FPGA chip. Use the present invention to receive and process inside the FPGA chip, and the composition of the single-line simplex temperature acquisition system in this embodiment is shown figure 2 . The temperature acquisition value received and processed by the FPGA chip is sent to the MCU, and the MCU performs small deviation average processing on multiple acquisition values.

[0039] The model of the digital temperature acquisition probe of the present embodiment is TSIC306, the FPGA adopts the EP4CE10E22I7N chip of INTEL (Intel) Company, and the MCU adopts the STM32F407ZGT6 chip of ST (Standard Semiconductor) Company. The output data rate of digital temperature acquisition in this embodiment is 8kbps, and one temperature acquisition value contain...

Abstract

The invention discloses a single-work asynchronous Manchester code receiving and decoding method, relates to the field of communication, and overcomes the defects of an existing single-work asynchronous Manchester code receiving and processing method. According to the invention, a hardware platform adaptive to an original asynchronous Manchester code is expanded, an original C language code is changed into a hardware language code, and the hardware language code is expanded to an FPGA chip from an MCU chip; The multi-channel asynchronous Manchester code data streams can be received on one FPGAchip, and the multi-channel asynchronous Manchester code data streams have the advantages of being concurrent, real-time, single-line and high-speed; According to the method, a good error detection fault-tolerant effect can be achieved only through a very small software and hardware scale, good balance between the complexity and the performance is achieved, and the method is suitable for receiving and decoding the asynchronous Manchester code.

Description

technical field [0001] The invention relates to the communication field, in particular to a simplex asynchronous Manchester code receiving and decoding method. Background technique [0002] Asynchronous Manchester code is a communication coding method that uses phase coding. It determines whether the transmitted symbol is 0 or 1 through the duration of high and low levels and the contextual relationship within a symbol period. During synchronous transmission, the sending end should send out the data signal and the symbol clock signal at the same time, and the receiving end uses the received clock signal to sample the received data and restore the symbol data. During asynchronous transmission, the sending end only sends the symbol signal and does not send the clock signal. Generally, the synchronization header is sent before the symbol data. The receiving end regenerates the local clock according to the received synchronization header, and the local clock samples and recovers...
