Embodiment Construction

[0039] The detailed technical features of the present invention will be further described below in conjunction with the accompanying drawings, so as to understand the present invention more clearly.

[0040] see figure 1As shown, it is a functional block diagram of a multifunctional fire emergency device with redundant judgment in the present invention. In the present invention, it is a redundant judgment device with three redundancy levels. The fire emergency device includes three smoke detection units, And a signal processing unit corresponding to the smoke detection unit, a power supply module and an action unit, and also includes a comparison unit, which is connected with a logic control unit, and the action unit includes a buzzer and a high-power LED lamps.

[0041] In the present invention, the output end of the first smoke detection unit 1 is connected to a first signal processing unit 2, which converts the detected smoke and gas concentration information into electric...

Abstract

The invention relates to a multifunctional fire fighting emergency device with a redundancy judgment function, which is a treble redundancy judgment device. The device provided by the invention comprises three smog detecting units, signal processing units corresponding to the three smog detecting units, and an action unit, as well as a comparing unit and a logic and control unit, wherein the comparing unit calculates the signal superposing degree of the second signal processing unit over the first signal processing unit, that of the third signal processing unit over the first signal processing unit, and that of the third signal processing unit over the second signal processing unit, and then sends the results to the logic and control unit where threshold determination is carried out; if the superposing degree is smaller than the threshold, that the smog concentration of the positions detected by two smog detecting units exceeds standard is detected. The emergency device adopts treble redundancy judgment, and as a result, the result is more accurate, and alarming measures can be promptly taken while misjudgment is avoided.

Description

technical field [0001] The invention relates to a fire emergency device, in particular to a multifunctional fire emergency device with redundant judgment. Background technique [0002] The fire-fighting emergency equipment in the prior art is mainly a fire-fighting emergency light, which is equipped with a detection circuit, a processing circuit and a switch circuit, and the light is set at a certain position in the circuit to detect the concentration of combustible gas or smoke in the air. . [0003] For example, the Chinese patent "A Smart Wireless Fire Emergency Light", application number: 201110385858.0 discloses a wireless fire emergency light. The emergency light module includes a power management module, an LED light source and a battery. The power management module circuit includes a switching power supply circuit. , charging circuit and discharging circuit, the communication and control module are used to control the charge and discharge information of the lamp mod...
