Description
Technical field
The utility model relates to a kind of warning system, specifically a kind of laboratory safety alarm system.
Background technology
The institution of higher education laboratory is as the important base of cultivating social skilled personnel, there is analysis, the testing tool of a large amount of advanced levels the inside, for the training of personnel provides the assurance on the material, simultaneously how having managed the laboratory becomes urgently open question of laboratory room managing personnel, and wherein the laboratory security protection is exactly a concrete and practical problem in the management.Along with use for a long time in the laboratory, problems such as the outmoded aging circuit of equipment will occur, because fire fighting device lacks, random wiring is drawn in the not strong private of people's fire-fighting idea, is easy to breaking out of fire.A lot of advanced important expensive experimental instruments are being deposited in the inside, laboratory, often because door and window is aging or damage, reasons such as door and window does not shut when people walk, to the lawless person opportunity has been arranged, also too many some student of personnel just spirits away and has taken away some valuables in the laboratory sometimes, has brought very big loss to the laboratory.Student and teacher's fire prevention, antitheft idea is not strong, and awareness of safety does not provide hotbed for the existence of hidden fire-fighting danger by force yet.Annual school can lose very big human material resources in the laboratory for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of laboratory safety alarm system, and this safety alarm system can be monitored the laboratory by multiple acquisition sensor, and carries out information processing by singlechip controller and realize security alarm.
The technical scheme in the invention for solving the technical problem is:
A kind of laboratory safety alarm system, comprise singlechip controller, smoke monitoring sensor, air pollution sensor, pyroelectric infrared sensor, sound and light alarm module, LCDs, key panel, wireless launcher, infrared counting module, described pyroelectric infrared sensor and infrared counting module are arranged at the doorway, laboratory; Described smoke monitoring sensor and air pollution sensor are arranged at breadboard inner roof, and aforementioned pyroelectric infrared sensor, infrared counting module, smoke monitoring sensor and air pollution sensor all are connected with wireless launcher; Described wireless launcher is connected with singlechip controller by its I/O mouth output terminal; Described singlechip controller also is connected with sound and light alarm module, LCDs and key panel by its I/O mouth output terminal.
Described sound and light alarm module is made of hummer and LED color lamp, and described infrared counting module is made of two optoelectronic switches.
Do further explanation and explanation with regard to the structure or the function of the utility model each several part below.
Singlechip controller: be located in the laboratory, the outside can be provided with control box.Singlechip controller is a control core of the present utility model.
Wireless launcher: be connected with air pollution sensor with pyroelectric infrared sensor, infrared counting module, smoke monitoring sensor, receive its data with wireless mode, and be connected with singlechip controller by I/O mouth output terminal, transfer data to singlechip controller.
Pyroelectric infrared sensor: when the breadboard doorway, pyroelectric infrared sensor can be responded to, and sends data to singlechip controller as the people, starts alert program.
LCDs: be used for the display room chamber of testing turnover number and related data.
Key panel: the laboratory internal staff can remove with password by key panel and report to the police, and external personnel then can not.
The sound and light alarm module: constitute by hummer and LED color lamp, when alarm takes place, buzzer call LED lamp flicker simultaneously.
Infrared counting module: constitute by two optoelectronic switches, realize detection to turnover laboratory number.
Smoke monitoring sensor and air pollution sensor: when breaking out of fire or laboratory inner air pollute reach certain limit after, smoke monitoring sensor and air pollution sensor detect and transmit data and give wireless launcher, and wireless launcher startup sound and light alarm module is reported to the police and sent an SOS.
The beneficial effects of the utility model are:
One, anti-theft feature: a when the breadboard doorway, can by wireless launcher send data to singlechip controller after pyroelectric infrared sensor detects as the people, starts alert program; B, the infrared counting module realizes the detection to turnover laboratory number.
Two, anti-fire function: when breaking out of fire or laboratory inner air pollute reach certain limit after, smoke monitoring sensor and air pollution sensor detect and also transmit data and give wireless launcher, wireless launcher sends alerting signal.
Description of drawings
Fig. 1 is that structure of the present utility model is formed synoptic diagram.
Wherein: 1 singlechip controller, 2 wireless launchers, 3 smoke monitoring sensors, 4 pyroelectric infrared sensors, 5 air pollution sensors, 6 infrared counting modules, 7 LCDs, 8 sound and light alarm modules, 9 key panels.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Structure of the present utility model is formed synoptic diagram and be please refer to shown in Figure 1, a kind of laboratory safety alarm system, comprise singlechip controller 1, smoke monitoring sensor 3, air pollution sensor 5, pyroelectric infrared sensor 4, sound and light alarm module 8, LCDs 7, key panel 9, wireless launcher 2, infrared counting module 6, described pyroelectric infrared sensor 4 and infrared counting module 6 are arranged at the doorway, laboratory; Described smoke monitoring sensor 3 and air pollution sensor 5 are arranged at breadboard inner roof, and aforementioned pyroelectric infrared sensor 4, infrared counting module 6, smoke monitoring sensor 3 and air pollution sensor 5 all are connected with wireless launcher 2; Described wireless launcher 2 is connected with singlechip controller 1 by its I/O mouth output terminal; Described singlechip controller 1 also is connected with sound and light alarm module 8, LCDs 7 and key panel 9 by its I/O mouth output terminal.
