Description
Technical field
The present invention relates to a kind of monitoring technical field to environmental toxic gas, specifically related to one kind are for Formaldehyde prison
The slave computer of control system.
Background technology
With the development of sensing technology, comprehensive environmental monitoring system application is more and more, and the slave computer of monitoring system will
After the data receiver of sensor acquisition, tentatively it is analyzed processing, is then uploaded to host computer or is sent to terminal, current
Being based on industrial computer or single-chip microcomputer slave computer, the price comparison of industrial computer is high, and the disposal ability of single-chip microcomputer is limited, man-machine friendship more
Mutually ability is poor, is not easy to on-site supervision management
Content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide a kind of for environmental monitoring system
Lower computer unit, has the characteristics that structure is simply easy to use.
To achieve these goals, the technical solution used in the present invention is: a kind of slave computer for Formaldehyde system,
Including: formaldehyde sensor (1), signal amplifier (2), central processing unit (3), DC source (4), led display (5), rs485
Communication interface (6), input set (7), data storage (8), wireless transmitter module (9), the outfan of described formaldehyde sensor (1)
It is connected with the input of signal amplifier (2), the input phase of the outfan of signal amplifier (2) and central processing unit (3)
Even, DC source (4), led display (5), rs485 communication interface (6), input set the inputs such as (7), data storage (8)
It is connected with the outfan of central processing unit (3) respectively, described outfan is connected with the input of wireless transmitter module (9).
Signal is amplified by formaldehyde sensor (1) by the trace signal collecting through signal amplifier (2), and central processing unit is again
Signal after amplifying is transmitted to wireless transmitter module (9) in order to will process knot by short message mode through rs485 communication interface (6)
Fruit is sent to mobile terminal.
Compared with prior art, present invention achieves data acquisition storage in monitoring, in real time display, communication, etc. various work(
Can, and low cost, efficiency high.
Brief description
Fig. 1 is the theory diagram of the present invention.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.As Fig. 1, including: formaldehyde sensor (1), signal
Amplifier (2), central processing unit (3), DC source (4), led display (5), rs485 communication interface (6), input set
(7), data storage (8), wireless transmitter module (9), the outfan of described formaldehyde sensor (1) is defeated with signal amplifier (2)
Enter end to be connected, the outfan of signal amplifier (2) is connected with the input of central processing unit (3), DC source (4), led show
Show device (5), rs485 communication interface (6), input set (7), the input such as data storage (8) respectively with central processing unit (3)
Outfan is connected, and described outfan is connected with the input of wireless transmitter module (9).
Signal is amplified by formaldehyde sensor (1) by the trace signal collecting through signal amplifier (2), and central processing unit is again
Signal after amplifying is transmitted to wireless transmitter module (9) in order to will process knot by short message mode through rs485 communication interface (6)
Fruit is sent to mobile terminal.
Above example is only used for the present invention, rather than limitation of the present invention, person skilled in the relevant technique,
Without departing from the spirit and scope of the present invention, various conversion or modification, therefore all equivalent technical sides can also be made
Case also should belong to scope of the invention, should be limited by each claim.
