Abstract
The utility model discloses a kind of closing space surrounding air safety detector; including concentration over-standard detector, communication protection pipe, switching controller, digital display prompting device, on-off controller; concentration over-standard detector is connected to switching controller by communication cable; communication cable is arranged on inside communication protection pipe, and switching controller is connected with digital display prompting device and on-off controller respectively by control line.The utility model is arranged on door and opened on switch; normal conditions Xiamen can be opened by door switch; when the gas concentration lwevel in enclosed environment is exceeded, the utility model can make door switch fail, so as to by making personnel can not open the door into enclosed environment and the safety of protection staff.
Description
Technical field
It the utility model is related to a kind of safe electronic equipment, more particularly to a kind of closing space surrounding air safety detection
Device.
Background technology
The storage space closed such as storage cellar, often occur makes environment have necessarily because gas concentration lwevel is too high
Danger, if personnel abruptly enter, apneic events can be produced, serious goes back entail dangers to life security.Using traditional two
Carbonoxide monitoring system is, it is necessary to which personnel carry out inspection confirmation before entering enclosed environment, and in most cases, personnel are to ignore
Check enclosed environment carbon dioxide situation and be directly entered, therefore traditional carbon dioxide monitoring system there is certain safety
Hidden danger.
The content of the invention
The purpose of this utility model：A kind of closing space surrounding air safety detector is provided, by being opened installed in enabling
Shut, when enclosed environment inner silica concentration of carbon is exceeded, door can be controlled can not to open the safety with support personnel.
Used technical scheme is to achieve these goals：
A kind of closing space surrounding air safety detector, including concentration over-standard detector, communication protection pipe, conversion and control
Device, digital display prompting device, on-off controller, described concentration over-standard detector are connected to switching controller by communication cable, institute
The communication cable stated be arranged on communication protection pipe inside, described switching controller by control line respectively with digital display prompting device and
On-off controller connects.
Preferably, described concentration over-standard detector employs infrared mode carbon dioxide sensor CO2/S-100 modules,
Described concentration over-standard detector is using three line TTL data-interfaces output gas concentration lwevel numerical value.
Preferably, described switching controller employs microcontroller chip PIC16F15345-I/SS.
Preferably, Omron solid-state relay G3MC-202PL is employed inside described on-off controller.
The utility model is arranged on door and opened on switch, and normal conditions Xiamen can be opened by door switch, work as envelope
When the domestic gas concentration lwevel of closed loop is exceeded, the utility model can make door switch fail, so as to by making personnel not open
Door enters the safety of enclosed environment and protection staff.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model closing space surrounding air safety detector.
Fig. 2 is the schematic diagram of the utility model closing space surrounding air safety detector.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2, a kind of closing space surrounding air safety detector, including concentration over-standard detector
1st, protection pipe 2, switching controller 3, digital display prompting device 4, on-off controller 5 are communicated, described concentration over-standard detector 1 passes through logical
Interrogate cable connection to be arranged on inside communication protection pipe 2 to switching controller 3, described communication cable, described switching controller 3
It is connected respectively with digital display prompting device 4 and on-off controller 5 by control line.
Described concentration over-standard detector 1 is set in inner sealing environment, described 2 setting through walls of communication protection pipe, connection
The communication cable of described concentration over-standard detector 1 is connected internally to the conversion and control outside enclosed environment through communication protection pipe 2
Device 3, described concentration over-standard detector 1 is in real time by the gas concentration lwevel data transfer of detection to switching controller 3, conversion control
Device 3 processed is in real time shown gas concentration lwevel data transfer to digital display prompting device 4.When switching controller 3 receive two
When carbonoxide concentration values exceed secure setting, switching controller 3 can control the power supply of the cut-out door switch of on-off controller 5,
So that door switch can not open door, so as to effectively avoid being directly entered the exceeded ring of gas concentration lwevel because personnel neglect
Border and situation about causing danger.
Preferably, described concentration over-standard detector 1 employs infrared mode carbon dioxide sensor CO2/S-100 moulds
Block, described concentration over-standard detector 1 is using three line TTL data-interfaces output gas concentration lwevel numerical value.
Preferably, described switching controller 3 employs microcontroller chip PIC16F15345-I/SS.
Preferably, Omron solid-state relay G3MC-202PL is employed inside described on-off controller 5.
The utility model is arranged on door and opened on switch, and normal conditions Xiamen can be opened by door switch, work as envelope
When the domestic gas concentration lwevel of closed loop is exceeded, the utility model can make door switch fail, so as to by making personnel not open
Door enters the safety of enclosed environment and protection staff.
