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.
