DSP based multipath detection device and detection method thereof

Abstract

The invention discloses a DSP based multipath detection device and a detection method thereof; the detection device comprises a signalling channel switching control module and a power supply module; the signalling channel switching control module synchronically sends a packet signal into a signal preprocessor module connected with the signalling channel switching control module; the signal preprocessor module is connected with a signal comparison module and an AD acquisition module; the signal comparison module and the AD acquisition module are connected with a master control chip; the master control chip is connected with a communication module, and connected with a storage module; the detection method comprises the following steps: starting, initializing all modules, carrying out device hardware signal pathway self-test, determining self-test success, determining whether to carry out fast rotation speed measurement or not, only carrying out rotation speed measurement, determining whether an assigned rotation speed is reached or not, simultaneously measuring rotation speed vibration amplitudes, checking whether a communication order exists or not, interrupting a subprogram, sending device work abnormity information, and finishing the work. The DSP based multipath detection device is high in cost performance, and strong in self-test ability, thus improving device versatility and interchangeability.

Description

technical field [0001] The invention belongs to an online detection device and a detection method thereof, in particular to a DSP-based multi-channel detection device and a detection method thereof. Background technique [0002] At present, the measurement equipment that can be used for synchronous detection of the speed and amplitude parameters of multiple rotating machinery and equipment can be roughly divided into two categories. The sensors used in the first category are mostly eddy current sensors, ultrasonic sensors, and laser sensors. Most of them have the characteristics of large size and high cost. It is suitable for measurement in the laboratory state, and does not have the conditions for large-scale application in the industrial field; the second type of measurement equipment uses a cheap speed measuring coil sensor, which has low measurement accuracy, low reliability of the measured results, and great application limitations. .
