摘要
近年来,道路交通信号控制机产品不断地更新迭代,这对用于信号机输出控制的驱动模块提出了更高的要求,输出状态检测也由最初的电压电流信号有无检测发展为电压电流、有功功率等信号大小的检测。目前,信号机驱动模块对输出信号的检测基本采用有效值检测,无源器件的个体差异使得输出采样电路形成一定的测量误差,所以在驱动模块出厂前都要对其进行严格的通道校准,开发一种既能解放人力,又能对信号机驱动模块进行自动化测试的装置就显得尤为重要。
In recent years,road traffic signal control machine products have been constantly updated and iterated,which has put forward higher requirements for the driver module used for signal output control.Output state detection has also evolved from the initial detection of voltage and current signals to the detection of signal sizes such as voltage and current,active power,etc.At present,the signal driver module basically uses effective value detection to detect the output signal.The individual differences of passive components cause certain measurement errors in the output sampling circuit.Therefore,strict channel calibration must be carried out before the driver module leaves the factory.It is particularly important to develop a device that can not only free manpower but also automatic testing of the signal driver module.
