Control device for controlling single device or multiple devices to start separately and stop separately with singe button, and control method

Abstract

The invention provides a control device for controlling a single device or multiple devices to start separately and stop separately with a single button, and a control method. A switch button SB, a contactor KM, an intermediate relay KA1 and an intermediate relay KA2 are connected by a circuit to form a start loop, a stop loop and a controlled loop. In the start loop, the switch button SB is connected in series with a normally closed point of the contactor KM, a normally closed point of the intermediate relay KA2 and a coil of the intermediate relay KA1, wherein a normally open point of the intermediate relay KA1 is connected in parallel with the normally closed point of the contactor KM. In the stop loop, the switch button SB is connected in series with a normally open point of the contactor KM, a normally closed point of the relay KA1 and a coil of the relay KA2, wherein a normally open point of the intermediate relay KA2 is connected in parallel with the normally open point of the contactor KM. In the controlled loop, the normally open point of the intermediate relay KA1 is connected in series with the normally closed point of the intermediate relay KA2 and a coil of the contactor KM, wherein the normally open point of the KM is connected in parallel with the normally open point of the intermediate relay KA1. According the control device and the control method for controlling single device or multiple devices to start separately and stop separately with the single button, the misoperation phenomenon of field operators and the labor intensity of operators are reduced.

Description

Technical field: [0001] The invention relates to a control device and a control method for single start and single stop of a single button, belonging to the technical field of electric control. Background technique: [0002] At present, there are many equipments in use in the production workshop, and the operation control buttons are also increased. The actual operation on site will inevitably be disturbed by the numerous control cabinet buttons. It also increases the cost of spare parts. In this case, it is particularly necessary for a single button to correspond to a single start and a single stop of a single or multiple devices. Invention content: [0003] The purpose of the present invention is to provide a control device and control method with a single button, single start and single stop, in view of the above-mentioned problems, which can effectively solve the technical problems of multiple devices and other equipment requiring a large number of button control, and...
