Abstract
The invention discloses a PLC-based automatic fire alarm device, including a smoke sensor, a temperature sensor, an A/D converter, a PLC, a self-rescue module, an audible and visual alarm and an upper computer. A signal output end of the smoke sensor and a signal output end of the temperature sensor are connected with a signal input end of the PLC through the A/D converter, a signal output end of the PLC is connected with the self-rescue module and the audible and visual alarm, and the PLC is connected with the upper computer through a serial communication interface. The PLC-based automatic fire alarm device provided by the invention is simple in structure, uses the PLC and is stable in performance and flexible to operate, and when a system detects a danger signal, self-rescue work can be automatically started, thereby reducing harm brought by a fire.
Description
Technical field
The present invention relates to a kind of fire-alarm, be specifically related to based on PLC fire automatic alarm device.
Background technology
Fire is combustible in time or the spatially disaster that causes of out of control burning, threatens the confusion of public security and civil order.Fire, bring human civilization progress, light and warm while also when it is out of hand, cause huge disaster to the mankind.Along with the development of economic society, each large, medium and small city has been driven to take on an entirely new look, the skyscraper of various looks is seen everywhere, the application material of buildings is more diversified, inflammable material is also increasing, add that the use of various electrical equipment and other electronic products in life is more and more extensive, overload makes electricity consumption, fault or the unexpected fire caused happen occasionally thus.Therefore the fire fighting device of perfect in shape and function is designed, very important to assuring the safety for life and property of the people.And the smog in the environment of scene of fire and temperature are detected in real time, the smog in precise monitoring environment and environment temperature, the potential safety hazard that discovery accident early exists, adopt an effective measure early stage at fire, there is great practical significance.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, stable performance, flexible operation, cheap, can automatic alarm based on PLC fire automatic alarm device.。
Based on PLC fire automatic alarm device, comprise smoke transducer, temperature sensor, A/D converter, PLC, module of saving oneself, audible-visual annunciator and host computer, the signal output part of described smoke transducer is connected with the signal input part of PLC through A/D converter with the signal output part of temperature sensor, the signal output part of PLC connects module of saving oneself, audible-visual annunciator respectively, and described PLC connects host computer by serial communication interface.
Further, described PLC is also connected with smog temperature indicator.
Further, the signal output part of described smoke transducer and be also connected with signal conditioning circuit between the signal output part of temperature sensor and A/D converter.
Preferably, described smoke transducer is resistance-type smoke transducer MQ-2.
Beneficial effect of the present invention is: the physics that the present invention sends fire, chemical phenomenon is (as burning gases, smoke particle, temperature, flame) respond to, convert the fire signal sensed to electric signal and be sent to PLC, PLC compares receiving the setting value that electric signal processes afterwards by analysis and host computer inputs, send control signal and send alerting signal when exceeding predetermined setting value PLC to audible-visual annunciator, and Real-time Smoke rank and real time temperature is demonstrated on smog temperature indicator, start and save oneself module (as fire water, flame snuffer etc.), managerial personnel check the floor and room number that catch fire by host computer, to make counter-measure in time, its structure is simple, utilizes PLC stable performance, flexible operation, when systems axiol-ogy is to danger signal, automatically can start the work of saving oneself, alleviate the harm that fire brings.
Accompanying drawing explanation
Fig. 1 is the structured flowchart that the present invention is based on PLC fire automatic alarm device.
Embodiment
Accompanying drawing discloses concrete structure of the present invention without limitation, and below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, based on PLC fire automatic alarm device, comprise smoke transducer, temperature sensor, A/D converter, PLC, module of saving oneself, audible-visual annunciator and host computer, the signal output part of described smoke transducer is connected with the signal input part of PLC through A/D converter with the signal output part of temperature sensor, the signal output part of PLC connects module of saving oneself, audible-visual annunciator respectively, and described PLC connects host computer by serial communication interface.Described PLC is also connected with smog temperature indicator.The signal output part of described smoke transducer and be also connected with signal conditioning circuit between the signal output part of temperature sensor and A/D converter.Described smoke transducer is resistance-type smoke transducer MQ-2.
