Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, the present invention comprises: the input end of input shaping unit 1 receives the SENT protocol frame data signal to be detected, and carries out shaping processing to it; The input end of low-pass filtering unit 2 is connected to the input end of input shaping unit 1, for The shaped signal is filtered; the CPU unit 3 judges the correctness of the data according to the SENT protocol, and encodes the data after the data verification is correct, and sends it to the output unit 4; the output unit 4 is used to output the data processed by the CPU unit 3 . CPU unit 3 processes the filtered signal through charging and discharging counting algorithm 5 , checking algorithm 6 and encoding algorithm 7 .

[0023] Usually the SENT protocol frame data signal is output by some point-to-point sensors on the car. Due to t...

Abstract

The invention relates to a SENT protocol frame data parsing converter data sampling parsing system. The system comprises an input shaping unit, a low-pass filtering unit, a CPU unit, and an output unit. The input end of the input shaping unit is used to receive SENT protocol frame data signals to be detected, and the input shaping unit is used for the shaping processing of the SENT protocol frame data signals. The input end of the low-pass filtering unit is connected with the input end of the input shaping unit, and is used for the filtering processing of the signals after the shaping processing. The CPU unit is used for the sampling of the data after the filtering, and is used to determine the correctness of the sampling data according to the SENT protocol, and is used to transmit the codes of the sampling data to the output unit after the verification of the sampling data. The output unit is used to output the data after the processing of the CPU unit. The problem of the lack of the SENT protocol parser in the domestic market can be solved.

Description

technical field [0001] The invention relates to the field of SENT protocol frame data analysis, in particular to a SENT protocol frame data analysis converter data sampling analysis system. Background technique [0002] At present, some point-to-point sensors in domestic high-end cars will be converted to the SENT protocol output mode, but they have not been used in specific applications and are currently in the research and development stage. The SENT protocol standard separates some sensors from the complex CAN bus. When using the CAN bus to send and receive data, a microprocessor chip with a CAN controller is required. The cost of this chip is relatively high, and the requirements of the SENT protocol do not require a CAN controller. , as long as there is only one I / O point, the data transmission time is saved, and the cost of the CPU detection unit is saved. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the technical p...
