Control system of fire water monitor

Abstract

The invention discloses a control system of a fire water monitor. The control system comprises a power module, an input module, a microcontroller and an output module, wherein the power module provides power for the whole control system; an output end of the input module is connected to an input end of the microcontroller; an input end of the output module is connected to an output end of the microcontroller and an output end of the output module is connected to an executive component of the fire water monitor; and the input module is provided with a pyroelectricity sensor the front end of which is provided with a narrow band filter through which only the infrared light with the wavelength of 4.06-4.4mu can be transmitted. After the technical scheme is adopted and the system adopts the microcontroller as a central controller, peripheral components are few and failure rate is low, and besides, as the front end of the pyroelectricity sensor is provided with the narrow band filter throughwhich only the infrared light with the wavelength of 4.06-4.4mu can be transmitted, sunlight, thunder and lightning light, electric welding light and other interference sources with the wavelength out of the range of 4.06-4.4mu are filtered out by the narrow band filter, thus ensuring the accuracy of detected flames and improving the working reliability of the system.

Description

technical field [0001] The invention relates to a fire-fighting water monitor, in particular to a control system for a fire-fighting water monitor. Background technique [0002] The control system of the fire water monitor generally includes a power supply part, a detection part, a processing part and an output part. The power supply part provides working power for the entire control system, and the detection part transmits the detected fire information to the processing part for analysis and processing. , and then control the output part to control the work of the fire water cannon to extinguish the fire. [0003] The control system of existing fire water monitor has following two problems: [0004] 1. The detection part generally uses an infrared sensor probe. There are a large number of interference sources when the infrared sensor probe is working, such as sunlight, lightning light, electric welding light, etc., which can easily lead to misoperation of the control syste...

Problems solved by technology

[0004] 1. The detection part generally uses an infrared sensor probe. There are a large number of interference sources when the infrared sensor probe is working, such as sunlight, lightning light, electric welding light, etc., which can easily lead to misoperation of the control system and low working reliability;

[0005] 2. Most of the program processing in the processing part uses PLC, with many peripheral components and high failure rate
