The invention discloses a controller high-voltage interlocking detection method and device and a controller, belongs to the technical field of high-voltage detection, and is used for solving the technical problems of low reliability, complex operation, high cost and the like of current high-voltage detection. The method comprises specific steps that whether light exist in the controller is detected; when it is detected that light exists in the controller, it is judged that the controller is in an external high-voltage disconnection state; when it is detected that no light exists in the controller, it is judged that the controller is in an external high-voltage connection state; and when the controller is in the external high-voltage disconnection state or external high-voltage connection state, a corresponding state signal is generated to perform high-voltage interlocking. The method, the device and the controller have the advantages of being easy and convenient to operate, low in cost, reliable in detection and the like.
本发明公开了一种控制器高压互锁检测方法、检测装置及控制器,属于高压检测技术领域,用于解决目前高压检测可靠性低、操作复杂、成本高等技术问题,具体为:检测控制器内部是否有光线;当检测到控制器内部有光线时,判断控制器处于与外部高压断开状态;当检测到控制器内部无光线时,判断控制器处于与外部高压连接状态;在控制器处于与外部高压断开状态或与外部高压连接状态时,产生对应的状态信号以进行高压互锁。本发明的方法、装置及控制器均具有操作简便、成本低、检测可靠等优点。
