Abstract

The application discloses a multi-type signal event recorder. The technical scheme adopted by the application comprises: a signal configuration module: selecting the type of input signal for each port, and configuring the flip threshold value corresponding to the input signal; a system initialization module: obtaining the current voltage value of the input signal, comparing the current voltage value with the corresponding flip threshold value, and defining the current reference logic value of the input signal; a polling module: comparing the current logic value of the input signal with the reference logic value thereof, and once there is a signal flip mutation, recording the input signal port number, the time when the flip occurs, and the time difference between the current time and the previous record; if the signal does not flip, directly processing the next input signal. The application can be conveniently used for testing the response time of the on-off quantity and the analog quantity of a DCS system, unnecessary reference voltage reference and current-to-voltage conversion work are avoided, and the testing work efficiency is improved.
