Signal machine illegal module detection method and device and readable storage medium

The invention discloses a method and a device for detecting illegal modules of an annunciator and a readable storage medium. The method comprises the following steps: S1, reading starting configuration parameters of each module in the annunciator after startup; s2, according to the starting configuration parameters and intersection channelization, obtaining the types and numbers of all modules of the signal machine in normal operation; s3, the control module of the annunciator issues a complete machine code query instruction, and collects complete machine codes of all modules in the annunciator; s4, judging whether the consistency of each module in the annunciator is greater than a preset threshold value or not, if so, entering a step S5, and if not, entering a step S6; s5, executing traffic signal control based on each module when each module in the annunciator is valid; s6, recording and reporting faults; according to the illegal module detection method and device and the readable storage medium, the legali
