Bidirectional wireless control system for low-voltage apparatus

Abstract

The invention discloses a bidirectional wireless control system for a low-voltage apparatus. The bidirectional wireless control system is characterized by comprising a power supply circuit (1), wherein the power supply circuit (1) is connected with an MCU (Microprogrammed Control Unit) control circuit (2); the MCU control circuit (2) comprises a wireless transmission circuit (201) and a signal detection circuit (202); the power supply circuit (1) is connected with the wireless transmission circuit (201) and the signal detection circuit (202) respectively; the signal detection circuit (202) is connected with the wireless transmission circuit (201) through an MCU serial port or an IO (Input-Output) port; the wireless transmission circuit (201) is capable of transmitting detection signals acquired from the signal detection circuit (202) to an external server or handheld terminal (3) equipment; the MCU control circuit (2) can be wirelessly controlled by the server or the handheld terminal (3) equipment; the MCU control circuit (2) can control an execution unit circuit (4). By adopting the bidirectional wireless control system, not only is one-way control on the low-voltage apparatus by a control module achieved, but also real-time power state information of the low-voltage apparatus can be transmitted to the control module, so that bidirectional transmission of data information is achieved, thus being relatively rapid and efficient.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power transmission and distribution safety protection, and specifically relates to a two-way wireless control system for low-voltage electrical appliances, which is used for detecting analog signals and digital signals of various low-voltage electrical equipment. Background technique [0002] At present, the control system of low-voltage electrical appliances is mainly based on two control methods, namely manual control and wired control. There are relatively few manual control applications, and the protocols generally used for wired control include MODBUS, CAN, DEVICENET and PROFIBUS. Relatively speaking, the application is safe, stable, and highly reliable; but at the same time, the cost is high, the convenience is not enough, and the terminal has certain limitations.
