The invention belongs to the technical field of escalators or moving sidewalks, and discloses a low-voltage safety circuit detection system of an escalator or a moving sidewalk, which comprises a fault signal acquisition module, a mainboard processing control module, a fault display module and a DC 24V power supply module, the mainboard processing control module receives the detection signal generated by the fault signal acquisition module, judges the state of the safety circuit according to the detection signal, and further controls the running state of the escalator; according to the method, a low-voltage detection mode is adopted, the problem of line voltage drop loss does not need to be considered, a transformer does not need to be independently configured for power supply, power supply is safer by adopting DC24V low voltage, the whole escalator or moving sidewalk does not carry voltage with safety risk for people to touch, the safety of the escalator is greatly improved, and the fault risk is reduced; the accuracy and reliability of fault detection are improved; the maintenance process is simplified, the maintenance efficiency is improved, and meanwhile the cost is greatly reduced.
本发明属于自动扶梯或自动人行道技术领域,公开了一种自动扶梯或自动人行道的低电压安全回路检测系统,包括:故障信号采集模块、主板处理控制模块、故障显示模块以及DC24V电源模块;主板处理控制模块接收故障信号采集模块生成的检测信号,并根据检测信号判断安全回路的状态,进而控制自动扶梯的运行状态;本发明通过采用低电压检测方式,无需考虑线路压降损耗问题,无需单独配置一个变压器供电,采用DC24V低电压供电更安全,使整个自动扶梯或自动人行道不带使人触及有安全风险电压,大大提高了自动扶梯的安全性,降低了故障风险;提高了故障检测的准确性和可靠性;简化了维修流程,提高了维修效率,同时大大减小了成本。
