An apparatus and method for reducing failures in traffic signals |
摘要 |
An apparatus and method for testing an independent monitoring circuit in an LED traffic signal is provided. The apparatus comprises: a proof test circuit embedded within the traffic signal; and a proof test device embedded within the traffic signal. The method comprises: via the proof test circuit, simulating a faulty traffic signal state; activating the independent monitoring circuit without switching the traffic signal into a high impedance state; energizing the proof test device; and via the proof test device, communicating externally the current state of the independent monitoring circuit. |
