Abstract

The utility model provides an environment monitoring and early warning device which comprises a main collector, a warning module which is connected with the main collector, a secondary collector and a plurality of sensors. The utility model is characterized in that both the main collector and the secondary collector are SCMs, the output ends of the sensors are connected to the input end of the main collector or the secondary collector, the secondary collector is connected with the main collector in parallel through a serial port module RS485 and the main collector is connected with a GSM module through an RS232 interface. The device continuously measure the on site information such as temperature, humidity, fire, theft, etc. in the monitored range by the sensors, and outputs the information to the main collector or the secondary collector. Datum is transmitted by the secondary collector to the main collector through the serial port module RS485. and the main collector carries out data processing and stores the datum in a memory. Alarm can be carried out according to processed result, and the numbers of the sensors are displayed. Measured result is simultaneously reported to a cell phone on duty through the RS232 interface and the GSM module, so that matter development is monitored and necessary measures are taken in time.

Description

The environmental monitoring prior-warning device

Affiliated technical field

The utility model provides a kind of environmental monitoring prior-warning device, belongs to microcomputer automatic monitoring control technology field.

Background technology

The fire failure major part causes that owing to temperature is too high existing fire detector only can be surveyed the fire that has taken place, and before fire took place, all at present linear constant temperature fire detectors (as temperature sensing cable) all can't send warning; Traditional " point type " temperature sensor can only be surveyed " certain point " temperature, can not cover the monitoring target of wire, more is difficult to a certain surface temperature is monitored.In order to guarantee the safety of lives and properties,, all need to carry out 24 hours to environment (temperature, theft etc.) continuous monitoring as market, warehouse, machine room, transformer station, generating plant etc. in a lot of important events.

The utility model content

The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, monitor the Environmental security information in certain scope and have the environmental monitoring prior-warning device of warning function automatically.Its technical scheme is:

Comprise main collector, connect the alarm module of main collector, from collector and some sensors, it is characterized in that: main collector, be single-chip microcomputer from collector, output termination master's collector of sensor or from the input end of collector, through serial port module RS485 and main collector and connect, main collector connects gsm module through the RS232 interface from collector.

Described environmental monitoring prior-warning device, main collector, all adopt C8051F021 type single-chip microcomputer from collector, 20, the 21 pin module taking alarm of main collector, 48,49 pin connect LQ-8100 type gsm module through serial port module RS232 successively, and respectively 54～55 pin from collector connect main collector through serial port module RS485.

Described environmental monitoring prior-warning device, main collector and respectively connect 8 sensors at most from collector, sensor are one or more of temperature sensor, humidity sensor, smoke transducer, theft-proof sensor.

Its principle of work is: sensor is a temperature sensor, humidity sensor, smoke transducer, one or more of theft-proof sensor, be installed in predetermined monitoring location, can measure the maximum temperature in the monitoring range, information such as fire and burglary, information outputed to main collector or from the input end of collector, from collector the conversion of signals of gathering is become digital signal after serial port module RS485 is sent to main collector, data are handled and are deposited in on-chip memory by main collector, can carry out early warning or warning according to result, and demonstrate number of sensor, simultaneously measurement result can be sent to mobile phone on duty, so that in time monitor impact development, take the necessary measures.
