Abstract

The invention discloses a control device of a spray electromagnetic valve in a coal yard. The device comprises a lightening production module, a low-voltage electric power carrier module, a singlechip module, a relay and an electromagnetic valve; the low-voltage electric power carrier module switches in a 220V power supply circuit through the lightening production module, and is simultaneously connected with the singlechip module; the singlechip module is sequentially connected with the relay and the electromagnetic valve; the low-voltage electric power carrier module is used for finishing the transmission and receiving of control signals; and the singlechip module is used for the treatment of the control signals and triggering the opening and closing of the relay, thus controlling the opening and closing of the electromagnetic valve. The device can be used for controlling the electromagnetic valve remotely, and the control signals are transmitted only by one electric cable, the wiring cost is lowered, and the device has the characteristics of simple wiring, stable system operation, and high expansibility, is simple to maintain and the like; and simultaneously the device has the functions of insulation and lightening production for the high-low voltage signals, and plays an effective role in protecting internal components.

Description

technical field [0001] The invention belongs to the technical field of solenoid valve control and low-voltage power carrier communication, and in particular relates to a control device for a spray solenoid valve in a coal yard. Background technique [0002] Power line communication technology appeared in the early 1920s. Its application scope is to filter electrical signals from the power line within the power supply line of the same transformer. Low-voltage power carrier technology was developed in the late 1990s. In recent years, low-voltage power line carrier PLC technology has become a research hotspot in communication systems, and it is regarded as an important field device bus communication technology in the future. At present, the low-voltage power carrier technology in many developed countries has entered the practical stage. my country's low-voltage power carrier technology started relatively late, but developed rapidly. Mainly developed power line multi-access di...
