Embodiment 1

[0036] Example 1, the detection device is equipped with a smoke temperature composite detector, a CO detector, a first gas detector and a second gas detector, and collects 5 kinds of smoke information: smoke, temperature, CO, CO 2 and HCN. The smoke temperature composite detector is composed of a photoelectric smoke detector and a thermistor type temperature detector. The CO detector uses a long-life electrochemical sensor with a detection range of 0-5000ppm and a service life of 5 years. The first gas detector adopts infrared type CO 2 The sensor and the second gas detector adopt semiconductor HCN sensor, both of which have a service life of more than 5 years. Each of the above-mentioned detectors independently completes the sampling, conditioning and temperature linear compensation of the sensing signal. The first wired communication module of the device is an RS485 bus module. The microcomputer unit of the device communicates with each detector through the RS485 bus to...

Embodiment 2

[0037] Embodiment 2, the detection device is provided with 4 kinds of detectors, collecting 5 kinds of flue gas information: smoke, temperature, CO, O 2 and CH 4 . The first gas detector uses O 2 The sensor and the second gas detector adopt CH 4 The sensors, both of which are infrared type sensors, have a service life of more than 5 years. The rest of the detector parameters are the same as the above-mentioned embodiment 1. The first wired communication module is an RS485 bus module. The second wired communication module is connected with the monitoring center by CAN bus. The device is not equipped with a wireless communication module and battery, and the monitoring center configures the backup power supply and performs switching management. This example method can be applied to various medium-sized buildings. like image 3 shown.

Embodiment 3

[0038] Example 3, the detection device is equipped with 4 types of detectors to collect 4 types of flue gas information: smoke, temperature, CO and CH 4 . The first gas detector adopts infrared type CH 4 The sensor, the second gas detector is canceled, and the rest of the detector parameters are the same as those in Embodiment 1 above. The first wired communication module is connected and communicated with each detector by TTL level standard. The device is not equipped with a second wired communication module, but is equipped with a GPRS wireless communication module, and the smoke alarm information is sent to the alarm center in the form of a short message. The device is equipped with a battery, and its power management mode is the same as that of Embodiment 1 above. The cost of the example method is low, and it can be applied to various high-rise residential buildings. like Figure 4 shown.

Abstract

The invention belongs to the technical field of fire fighting equipment and in particular relates to an online fire smoke detecting device. The online fire smoke detecting device is composed of a smoke and temperature composite detector, a CO detector, a first gas detector, a second gas detector, a microcomputer unit, a first wired communication module, a second wired communication module, a wireless communication module, a power supply management unit, a signal processing box, a standby battery pack and an installing base. The four detectors are respectively connected with the first wired communication module. The first wired communication module, the second wired communication module, the wireless communication module and the power supply management unit are connected with the microcomputer unit. The second wired communication module and the wireless communication module are connected with an external communication transmission network simultaneously. The power supply management unit is simultaneously connected with an external power supply. The online fire smoke detecting device can collect environment parameters of smoke concentration, dangerous gas concentration, thermal radiation temperature and the like, provides guarantee for smooth implementation of evacuation, escaping and emergency rescue, and simultaneously is moderate in range ability, high in reliability, long in service life and convenient to expand.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to an online smoke detection device for fire monitoring. Background technique [0002] The fire smoke detection device is mainly used in some key parts of the building, such as the elevator front room, stairs, walkways, entrance and exit passages and other evacuation and escape areas. Because the people trapped in the fire tend to gather here, or wait for rescue, or look for escape opportunities. [0003] At present, people know through a large number of fire cases that smoke is the number one killer in a fire, and most casualties in a fire are not directly burned to death, but are killed by fire smoke. Fire smoke greatly hinders people's escape and evacuation in fire, and has become the main cause of death. In the long-term struggle with fire, people have concluded that fire smoke has three characteristics: toxicity, light reduction and terror. Among ...
