Utility model content
The purpose of this utility model is to provide response type gas detecting alarm system, solves the technical matters that existing gas detecting alarm system cannot make zero-time difference response.
In order to achieve the above object, the utility model provides following technical scheme:
Response type gas detecting alarm system, comprise combustible gas sensor, A/D converter, single-chip microcomputer, alarm and teleswitch, described combustible gas sensor, A/D converter, single-chip microcomputer is connected in turn with alarm, the transmitter unit of described teleswitch is connected with described single-chip microcomputer, in the control circuit of receiving element access response equipment, when being greater than the combustable gas concentration value preset in described single-chip microcomputer when the combustable gas concentration in air, described single-chip microcomputer sends alerting signal to alarm, transmitter unit simultaneously to described teleswitch sends control signal, control transmitter unit sends signal control response equipment to receiving element and makes corresponding response.
Further, described teleswitch can arrange multiple, and the receiving element of described multiple teleswitch accesses in the control circuit of corresponding response equipment respectively, controls corresponding response equipment and responds.
Further, described response equipment can be exhaust fan, automatic window and spray equipment etc.When being greater than the combustable gas concentration value preset in described single-chip microcomputer when the combustable gas concentration in air, described single-chip microcomputer sends control signal to the transmitter unit of described teleswitch, control transmitter unit and send the unlatching of signal control exhaust fan to receiving element, automatic window is opened, and the response equipment such as spray equipment unlatching makes corresponding response.
Further, LED charactron is also comprised; Described LED charactron is connected with described single-chip microcomputer, shows the combustable gas concentration detected in real time.
Further, described response equipment is power distribution cabinet.In time by the dump of whole inflammable gas leak area, prevent from, because electric spark causes flammable gas explosion, causing more serious consequence.
Further, accumulator and controller is also comprised; Described accumulator is connected with described gas detecting alarm system and mains-supplied system respectively by controller.It is that accumulator charges that controller controls mains-supplied system, and charging completely in situation, controls to stop charging.When mains failure, accumulator provides power supply to described gas detecting alarm system, ensures the normal operation of gas detecting alarm system.
The utility model cannot make the technical matters of zero-time difference response for existing gas detecting alarm system, propose response type gas detecting alarm system of the present utility model, set up teleswitch, when aerial combustable gas concentration is greater than the combustable gas concentration value preset in described single-chip microcomputer, the transmitter unit that single-chip microcomputer can control teleswitch in real time transmits to receiving element, and receiving element controls response equipment and makes response.Response equipment can arrange multiple, before personnel reach the spot and sue and labour, realizes the concentration reducing inflammable gas timely and effectively.
Electric power system in power distribution cabinet can also directly be cut off by gas detecting alarm system of the present utility model, avoids because electric spark causes the consequence of flammable gas explosion to occur.Further in order to ensure the normal work of gas detecting alarm system, set up accumulator, when cutting off the electricity supply for gas detecting alarm system is powered.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structured flowchart of the utility model response type gas detecting alarm system.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
According to Fig. 1, response type gas detecting alarm system of the present utility model, comprise combustible gas sensor (concrete employing semiconductor combustible gas sensor MQ-2), A/D converter, single-chip microcomputer, alarm (specifically adopting hummer) and teleswitch, described combustible gas sensor, A/D converter, single-chip microcomputer are connected in turn with alarm, the transmitter unit of described teleswitch is connected with described single-chip microcomputer, in the control circuit of receiving element access response equipment.The gas concentration information collected is converted into electric signal by described combustible gas sensor, after converting electrical signals to digital signal by A/D converter, digital signal is sent into single-chip microcomputer, data processing is completed by single-chip microcomputer, the safety value set compares with programming, when the information collected exceedes safety value, reported to the police by Micro Controller Unit (MCU) driving alarm (hummer), drive the transmitter unit of teleswitch to transmit control signal to receiving element simultaneously, respond to control corresponding response equipment.
In practical application, described teleswitch can arrange multiple, and the receiving element of described multiple teleswitch accesses in the control circuit of corresponding response equipment respectively, controls corresponding response equipment and responds.Described response equipment can be exhaust fan, automatic window and spray equipment etc.When being greater than the combustable gas concentration value preset in described single-chip microcomputer when the combustable gas concentration in air, described single-chip microcomputer sends control signal to the transmitter unit of described teleswitch, control transmitter unit and send the unlatching of signal control exhaust fan to receiving element, automatic window is opened, and the response equipment such as spray equipment unlatching makes corresponding response.
