The locomotive speed acquisition device comprises at least two speed acquisition units, an arbitration unit and a speed sensor, wherein the speed sensors is electrically connected with each speed acquisition unit separately, each speed acquisition unit is electrically connected with the arbitration unit; each speedacquisition unit comprises a signal acquisition circuit, a self-inspection circuit and a microprocessor, wherein the microprocessor is electrically connected with the signal acquisition circuit and the self-check circuit separately, and the signal acquisition circuit is electrically connected with the self-checking circuit. The locomotive speed acquisition device and a control method have high precision, high reliability and high safety.

Description

technical field [0001] The invention relates to the technical field of speed acquisition, in particular to a high-precision, high-reliability and high-safety locomotive speed acquisition device and control method. Background technique [0002] Locomotive speed is an important index related to locomotive operation safety. The low-speed and high-speed speed measurement performance of the photoelectric speed sensor is relatively stable, and is less affected by temperature. It has the advantages of high precision, high resolution, high reliability and fast response, and has been widely used in the field of detection and control. [0003] However, most of the existing speed acquisition devices are single-channel or single-processor acquisition. The speed acquisition path and calculation path are single. When the acquisition channel fails or the processor speed calculation is abnormal, safe and effective speed information cannot be obtained. And when the acquisition channel fail...
