Annunciator monitoring standby machine

Abstract

The invention discloses an annunciator monitoring standby machine. The machine comprises a case. A main control board is arranged in the case. A micro-processing controller is arranged on the main control board. An annunciator output state acquisition interface, an air switch output signal acquisition interface and a mains supply input signal acquisition interface are formed in one side of the case, and the annunciator output state acquisition interface, the air switch output signal acquisition interface and the mains supply input signal acquisition interface are all electrically connected with the main control board. According to the invention, the output states of 44 paths of annunciators can be acquired through the annunciator output state acquisition interface, the air switch output signal acquisition interface and the commercial power input signal acquisition interface, various fault conditions are analyzed and processed, the power input voltage can be detected, the brightness ofthe signal lamp can be analyzed, the operation state of the signal machine can be comprehensively and effectively detected, an alarm is given in time when a fault is detected, the fault reason and position are simply and visually displayed through the GPS module, and a manager can conveniently, rapidly and accurately maintain equipment.

Description

technical field [0001] The invention relates to the technical field of traffic signal machine detection and alarm technology, in particular to a signal machine monitoring standby machine. Background technique [0002] The main function of the signal machine monitoring standby machine is to monitor the operating status of the signal machine. When the signal machine fails, it can report the cause of the failure to relevant personnel in time to solve the intersection equipment failure and prevent traffic congestion. [0003] Similar products on the market mainly have the following deficiencies: [0004] 1. The number of detection channels is small, which may easily lead to false alarms; [0005] 2. It does not have the function of viewing the signal status in real time, and the running status of the intersection cannot be fed back to the manager; [0006] 3. It does not have the function of networking and lacks the function of centralized management of the center; [0007] 4...
