Abstract

The utility model discloses a forest fire monitoring apparatus, consisting of a smog sensor, a single-chip microcomputer, a memory chip, a signal acquisition and over-standard alarm circuit; wherein, the output end of the smog sensor is connected with the input ends of both the single-chip microcomputer and the alarm circuit simultaneously; the single-chip microcomputer is also connected with the memory chip to input data; which is characterized that the single-chip microcomputer can automatically detect the smog concentration at the pre-set observation points in the forest, collect the data to the local server and display on site, and then send out alarm when the smog concentration is over standard; meanwhile, the data is sent to the remote control centre through the network; the development of network technology, particularly the fast development of the internet technology provides convenient way for remote data transmission; the data can be transmitted to anywhere without limitation of distance, so large range centralized monitoring is made possible.

Description

The forest fire monitoring device

Technical field

The utility model is a kind of device of the forest fire dangerous situation being monitored automatically and reporting to the police with computer networking technology, belongs to automatic monitoring technique field.Be a kind of forest fire monitoring device specifically.

Technical background

Taking place frequently of countries in the world forest fire brings on a disaster to people's life, brings about great losses to national economy.Utilize the one-chip computer automatic real-time monitoring, by the long-range transmission information of computer networking technology, accomplish timely forecast, what avert a calamity is one of efficient ways.The network technology especially develop rapidly of Internet technology provides approach easily to remote data transmission, and it is not subjected to the restriction of distance, almost can arrive Anywhere, and this is for realizing that Centralized Monitoring has been created good condition on a large scale.Overcome untimely, inaccurate in traditional artificial inspection mode, problem wastes time and energy.

Summary of the invention

Goal of the invention of the present utility model provides a kind of forest fire monitoring device, this device can detect automatically the smokescope of each default observation station in the forest, exceed standard warning, regularly send presence server with institute survey data, presence server is analyzed each observation station data, and, by network information is transmitted remote control center simultaneously to the supervision of black spot emphasis.

The utility model forest fire monitoring device is made up of smoke transducer, single-chip microcomputer, memory chip, signals collecting and the warning circuit that exceeds standard; The output terminal of smoke transducer connects the input end of single-chip microcomputer and warning circuit simultaneously, and as the data input of single-chip microcomputer, single-chip microcomputer also is connected to memory chip.

Concrete is connected to: the output terminal of smoke transducer is the input end that the output terminal B-B ' of QM-N2 meets transistor BG3DG6,2 pin input ends of the output termination 555 of BG3DG6, it is the JRC-5M-12V input end that 555 3 pin output terminals directly start warning circuit, 555 3 pin output simultaneously meets the P3.2 that single-chip microcomputer is a single-chip microcomputer 8031, the input end of the P3.0 of single-chip microcomputer 8031, P3.1

termination

7520,7520 output meet serial interface circuit RS485 and are used for communicating by letter with host computer.

The utility model is the forest fire monitoring device.This device detects automatically with the smokescope of single-chip microcomputer to each default observation station in the forest, and with data gather to presence server on-the-spot show, warning exceeds standard.By network data are delivered to remote control center simultaneously.The network technology especially develop rapidly of Internet technology provides approach easily to remote data transmission, and it is not subjected to the restriction of distance, almost can arrive Anywhere, and this is for realizing that Centralized Monitoring has been created good condition on a large scale.
