The invention discloses an intelligent traffic signal lamp fault detection and alarm system comprising signal lamp working state collectors, a signal lamp controller working state collector, and a central server/wireless mobile data sender. Each signal lamp working state collector is connected with a signal lamp, and is used to collect the current working state of the signal lamp and transmit the working state to the signal lamp controller working state collector. The signal lamp controller working state collector is arranged between connecting lines of the signal lamps and a signal lamp controller, and is used to collect an output signal of the signal lamp controller and compare the output signal with the current working state of each signal lamp. The signal lamp controller working state collector is connected with the central server through a data communication network to process fault information and send the fault information to users, or the signal lamp controller working state collector is connected with the wireless mobile data sender to send the fault information to users. The accuracy and real-time performance of signal lamp fault detection and alarm are improved. The means of detection is enhanced, and signal lamp fault reporting is more comprehensive.
