System fault wireless alarming device

Abstract

The invention discloses a water system fault wireless alarming device which comprises a signal acquiring unit, a programmable controller, a short message controller and a plurality of handheld communication devices, wherein the signal acquiring unit comprises a plurality of signal acquiring elements arranged on each device of the water system, the programmable controller is connected with the signal acquiring unit so as to receive a state signal transmitted from the signal acquiring unit and output a fault signal; an action program for arranging the logical relation between the state signal and the fault signal is prestored in the programmable controller; the short message controller is connected with the programmable controller so as to receive the fault signal transmitted from the programmable controller and send a short message with the content corresponding to that of the fault signal; and the plurality of handheld communication devices are accessed into a public mobile telecommunication network so as to receive the short message from the short message controller through the public mobile telecommunication network. The system fault wireless alarming device has the advantages of being simple in structure, high in alarming reliability and capable of directly improving an original control system.

Description

Technical field: [0001] The invention relates to an automatic control device, in particular to a wireless alarm device for system failure. Background technique: [0002] General automatic control devices are all for detection, monitoring, fault alarm and automatic feedback control for the process or state of a certain system. Devices belonging to the fault alarm category first obtain the fault signal from the operating system, and then process the fault signal, and the processed signal then triggers the alarm device. The working mode of the alarm device can be wired or wireless Yes, the trigger signal in the wired alarm device is directly transmitted to the alarm through the cable, and the trigger signal in the wireless alarm device is transmitted to the alarm through wireless transmission and receiving devices. At present, the commonly used alarms all use signals such as light and sound to alarm at the control site, such as the control station, so that the system managemen...
