Equipment control device with line monitoring function and equipment control system with line monitoring function

Abstract

The embodiment of the invention discloses an equipment control device with a line monitoring function and an equipment control system with a line monitoring function. The device comprises a switching unit, a line monitoring unit and an output unit, wherein the switching unit switches between the line monitoring unit and the output unit; the line monitoring unit is connected with the line of controlled equipment through the switching unit, distributes a monitoring signal to the controlled equipment through the line of the controlled equipment and outputs a signal of an abnormal line when the proportion of the monitoring signal distributed to the controlled equipment is different from the proportion of a monitoring signal required under the condition of a normal line; the output unit is connected with the line of the controlled equipment through the switching unit and outputs a control signal to the controlled equipment. The equipment control device in the system monitor the state of the line of the controlled equipment and informs a control center when the line is abnormal. When in use, the invention can monitor the state of the line and can overhaul conveniently in time when the line has fault, thereby improving the control reliability.

Description

technical field [0001] The invention relates to the fields of fire protection and security protection, in particular to an equipment control device and an equipment control system with a line monitoring function. Background technique [0002] In fire protection and security systems, there are a series of equipment that only work in the event of a fire, but in normal times, these equipment are in a non-working state, such as pump equipment such as spray pumps, valve equipment such as air supply valves, fire power supplies, Linkage equipment such as fire broadcasting system and sound and light alarm. When a fire occurs, the above-mentioned equipment is switched to the working state through the signal output device or the power output device. Among them, the above-mentioned equipment can be switched to the working state by manually controlling the signal output device or the power output device, or it can be used for fire protection and security protection. After the system de...

AI Technical Summary

Problems solved by technology

[0005] The line where the controlled equipment is located may be faulty. Since the existing signal output device and power output device are usually in a non-working state, the signal output device or power output device cannot know the state of the line where the controlled equipment is located, let alone output the controlled device. The status of the line where the controlled equipment is located, or report the status to the control center of the fire protection and security system, so that in the event of a fire or other abnormal conditions, if the line where the controlled equipment is located fails, the signal output device and power output device cannot Switch the controlled device to the working state, causing the controlled device to fail, causing serious consequences
