Abstract

The present utility model provides an industrial gas wireless remote alarm terminal device. The device comprises a gas detection module, a main control module, a user interaction module, an acousto-optic alarm module and a wireless module, and the device is characterized in that the main control module is respectively connected with the gas detection module, the user interaction module, the acousto-optic alarm module and the wireless module. The gas detection module is used for converting gas concentration of a monitored area into an analogue signal and realizing analog-to-digital conversion, the main control module is then used for judging the gas concentration and to determine whether to alarm or not according to a lowest alarm limiting value set by the user interaction module, the gas concentration data and the information of whether to alarm or not are subjected to communication coding and emitted to a host computer end through the wireless module, and an alarm is given out by the acousto-optic alarm module when the gas concentration exceeds the alarm limiting value.

Description

Industrial gas wireless remote alarming end device

Technical field

The utility model relates to a kind of industrial gas warning device, especially industrial gas wireless remote alarming end device.

Background technology

In recent years, gas poisoning takes place frequently in iron and steel metallurgy enterprise, has caused great casualties and property loss.Trace it to its cause mainly produce or work progress in do not carry out the safety work regulation in real earnest and cause, but wherein also exist the incomplete problem of gas alarm system configuration.

Summary of the invention

In view of above these situations, the utility model provides a kind of industrial gas wireless remote alarming end device.

The utility model provides a kind of industrial gas wireless remote alarming end device, comprise coal gas detection module, main control module, user interactive module, sound and light alarm module, wireless module, it is characterized in that: main control module is connected with coal gas detection module, user interactive module, sound and light alarm module, wireless module respectively.At first to pass through the coal gas detection module, convert the gas concentration of monitored area to simulating signal, and carry out analog to digital conversion, main control module is judged gas concentration, minimum warning limit value according to the user interactive module setting judges whether to report to the police, then gas concentration data and the information of whether reporting to the police are emitted to upper computer end through communication coding by wireless module, report to the police when surpassing warning limit value sound and light alarm module.

The beneficial effects of the utility model are, have improved industrial security, avoid the generation of accident, and this device adopted Radio Transmission Technology, improve the reliability and stability of data transmission, have higher practical value.

Description of drawings

Fig. 1 is theory diagram of the present utility model.

Embodiment

In Fig. 1, the utility model provides a kind of industrial gas wireless remote alarming end device, comprise coal gas detection module 1, main control module 2, user interactive module 3, sound and light alarm module 4, wireless module 5, it is characterized in that: main control module 2 is connected with coal gas detection module 1, user interactive module 3, sound and light alarm module 4, wireless module 5 respectively.At first to convert the gas concentration of monitored area to simulating signal by coal gas detection module 1, and carry out analog to digital conversion, 2 pairs of gas concentrations of main control module are judged, the minimum warning limit value that arranges according to user interactive module 3 judges whether to report to the police, then gas concentration data and the information of whether reporting to the police are through communication coding, be sent to upper computer end by wireless module 5, report to the police when surpassing warning limit value sound and light alarm module 4.

The electrochemical sensor TGS5042 of the Japanese Figaro of coal gas detection module 1 employing company, detecting the gas concentration scope is 0～10000ppm, has " zero " power consumption, long-life (more than 5 years), high selectivity, high precision, output rectilinearity, electric property and the advantage such as stablizes.It is to decide the potential point solution as ultimate principle, and when there was carbon monoxide in environment, the electromotive force that produces between the both positive and negative polarity of sensor just can be used as signal output.It is the core of control module that main control module 2 has adopted the single-chip microcomputer of the MSP430 series of TI company, is the mixed-signal processor of a kind of l6 position super low-power consumption.User interactive module 3 main keyboard load modules and display apparatus module consist of, with the opening and closing by keyboard control system, and the display mode of data and the limit value of warning.Display apparatus module adopts the OCMJ5XIO of 160 * 80 dot matrix Chinese picture and text liquid crystal picture, and the inside of this module is owing to containing the simplified character library of GB one-level, so that the demonstration of Chinese character is unusually convenient; Wireless module 5 adopts the NRF903 wireless communication module of NORDIC company, the NRF903 module is used the open ISM band of the 433MHZ that exempts from licence, high workload speed 50Kbps, efficient GFSK modulation, antijamming capability is strong, be particularly suitable for the Industry Control occasion, have 125 channels, satisfy multi-point and frequency hopping communications needs, built in hardware CRC error detection and the control of point-to-multipoint delivery address, wealthy ground of opening transmission range reaches 400 ~ 500m, if configuration high-gain sucker antenna, the open ground maximum transmission distance can reach 600m, meets the requirement of wireless remote gas alarm fully.

Claims
