Problems solved by technology

Due to installation restrictions in the tunnel, parameters such as the detection sensitivity of the smoke detector cannot be adjusted after installation
The power supply of existing wireless smoke detectors adopts battery power supply or wired power supply. The use of wired power supply increases more construction and wiring costs. When the battery is used, the battery must be replaced when the power is insufficient, otherwise the device cannot correctly detect the smoke in the tunnel, but the battery Powered smoke detectors have no means of battery voltage detection and can only be replaced periodically

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 1 As shown, the tunnel wireless light intensity detector is composed of a smoke sensor, an amplifier circuit, an A / D conversion circuit, a single-chip microcomputer as the main control, a battery monitoring circuit, and a wireless communication module. The smoke signal acquisition circuit consists of a smoke sensor and an analog amplifier circuit (AD8607), which converts the smoke signal into an analog electrical signal. The A / D conversion circuit (AD5160) converts the analog signal output by the smoke signal acquisition circuit into a digital signal that can be recognized by the single-chip microcomputer and sends it to the single-chip microcomputer. The battery monitoring circuit collects the voltage of the power supply battery, and converts the data collected by the voltage into a digital signal that the single-chip microcomputer can recognize thro...

Abstract

The invention discloses a tunnel wireless smog detector. The tunnel wireless smog detector comprises a single-chip microcomputer, a wireless communication module, a battery monitoring circuit, an A / D conversion circuit, an amplification circuit and a smog sensor. The wireless communication module, the battery monitoring circuit and the A / D conversion circuit are respectively connected with the single-chip microcomputer. The A / D conversion circuit is connected with the amplification circuit which is connected with the smog sensor. The wireless smog detector is realized so that the constraint of the wiring requirement of the smog detector in the tunnel can be relieved and tunnel construction cost can be reduced. Smog detection is performed on all point positions in one tunnel, and smog machines are started to discharge smog by acquisition equipment when concentration of smog is oversized so that intelligent control of equipment in the tunnel is realized. Monitoring data of battery voltage can be provided because of battery voltage monitoring. When voltage is undersized, alarm prompting can be performed so that great basis can be provided for later maintenance of the equipment, and workload of maintenance of the equipment in the tunnel can be greatly reduced.

Description

technical field [0001] The invention relates to a smoke detector for security alarm, in particular to a tunnel wireless smoke detector. Background technique [0002] Most of the existing wireless smoke detectors are used indoors, and smoke detectors in tunnels [0003] Usually connected by wire. Due to installation restrictions in the tunnel, parameters such as the detection sensitivity of the smoke detector cannot be adjusted after installation. The power supply of existing wireless smoke detectors adopts battery power supply or wired power supply. The use of wired power supply increases more construction and wiring costs. When the battery is used, the battery must be replaced when the power is insufficient, otherwise the device cannot correctly detect the smoke in the tunnel, but the battery Powered smoke detectors have no means of battery voltage detection and can only be replaced periodically. Contents of the invention [0004] In view of the above-mentioned state o...
