Abstract

The invention relates to a unit disaster control method and system. The disaster control system adopts an analog disaster automatic alarm system. The system includes a processor, an acquisition module, an execution module and an early warning module. The processor is connected with the acquisition module, the execution module and the early warning module respectively. The early warning module is connected, and the processor processes the data collected by the acquisition module and judges whether there is an abnormality and the type of the abnormality. When the environmental change value exceeds a certain range, an alarm will be issued. If the environmental change value does not develop, the alarm will stop. If the rate of change continues to accelerate, the actuator will be controlled to take measures, and the early warning module will be controlled to alarm. The invention can significantly reduce the interference of environmental temperature, humidity and other factors, greatly improves the reliability and stability of disaster control, reduces the false alarm rate, is convenient to use, and has low maintenance cost.

Description

A unitary disaster control method and system

technical field

The invention relates to a unit type disaster control method and system.

Background technique

At present, no matter it is a high-rise building of a common type (such as a residential building) or a luxury type (such as a high-end hotel). All pay more and more attention to the popularization and application of fire prevention and safety technology. Because multi-storey, small high-rise or high-rise buildings have many floors and dense population, if a fire breaks out, it will be difficult to evacuate and rescue, which will inevitably cause serious casualties and property losses. In order to ensure the safety and reliability of high-rise buildings, an automatic fire alarm and fire protection system with high reliability and good real-time performance must be designed. At present, the research on building fires is mainly focused on early warning. However, everything cannot be so smooth. What if the early warning system is broken or unattended, and the current early warning system is mainly concentrated in large spaces or building groups. , without small or unitary warnings. Though multiple automatic fire alarm systems have been arranged, these fire-fighting devices are mostly fire-fighting sprinklers connected with pipelines, and when a fire occurs, the fire-fighting sprinklers are opened. Although some fire-fighting devices have relatively comprehensive fire-extinguishing functions, most of them still belong to the offline mode, and finally rely on people to contact the fire department, there is a certain delay, and often cause heavy losses due to failure to call the police in time. In addition, when a fire breaks out, people usually rush to escape due to panic, and forget to find the source of fire, which causes the spread of the fire and brings heavy losses. If it is possible to work directly online, property damage and casualties will be greatly reduced. In addition, when a fire occurs, a large amount of smoke will be produced, and some even contain toxic gases such as CO and formaldehyde, and there are no effective smoke exhaust measures.

Contents of the invention

The purpose of the present invention is to solve the existing unit disaster control method with a certain time delay, failure to report to the police in time and possible losses caused by false alarms, thereby proposing a unit disaster control method.

The present invention proposes a kind of unit disaster control method in order to solve above-mentioned technical problem, and the concrete steps of this control method are as follows:

1). Use the temperature sensor, humidity sensor, CO ₂ detector, liquefied petroleum gas detector, smoke detector and infrared detector set in the room to collect temperature, humidity, CO ₂ concentration, liquefied petroleum gas content, smoke concentration and whether the home is someone's information;

2). According to the collected temperature, humidity, _CO2 concentration, liquefied gas content, flue gas concentration and their respective change rates, judge whether there is any abnormality. If the above information is normal, do not do any processing. If the above information is abnormal , to determine the specific type of abnormal phenomenon;

3). If the temperature, CO ₂ concentration and smoke concentration in the room exceed the standard, an alarm signal will be issued, and it will be judged whether the rate of change of the temperature, CO ₂ concentration and smoke concentration in the room continues to accelerate, and if it continues to accelerate, it will open Ventilation and sprinkler installations in the room, and immediately activate the alarm to notify the householder, property and fire department;

4). If the liquefied gas content exceeds the standard, first determine whether there is anyone in the home, if someone activates the indoor alarm immediately, if no one immediately activates the alarm, notify the householder and the fire department and open the ventilation device;

5). If the CO ₂ concentration and smoke concentration in the room exceed the standard, open the ventilation device to reduce the CO ₂ concentration and smoke concentration.

The present invention also proposes a unit type disaster control system, the system includes a processor, an acquisition module, an execution module and an early warning module, the processor is respectively connected with the acquisition module, the execution module and the early warning module, and the processor collects the Process the data and judge whether there is an abnormality and the type of the abnormality. If the temperature, CO ₂ concentration and smoke concentration in the collected room exceed the standard, the control and early warning module will send an alarm signal and judge the collected temperature and CO ₂ concentration. and whether the rate of change of smoke concentration continues to accelerate. If it continues to accelerate, the control execution module will take action, and the control early warning module will notify the head of the household, the property and the fire department. Whether there is someone, if there is someone, the control early warning module sends an alarm, if there is no one, the control execution module makes an action, and the control early warning module notifies the head of the household, the property and the fire department at the same time.

Described data collection module comprises data collector and the temperature sensor that links to each other with data collector input end, humidity sensor, _CO Detector, liquefied petroleum gas detector, smoke detector and infrared detector, the output end of data collector Connect to the input of the processor.

The execution module includes an actuator controller and a ventilation device and a water spray device respectively connected to the output end of the actuator controller, and the input end of the actuator controller is connected to the output end of the processor.

Described early warning module comprises siren and GPRS/GSM communication unit, and siren and GPRS/GSM communication unit are connected with the output terminal of processor, and siren is used for reminding householder and property management to have disaster to take place, and GPRS/GSM communication unit is used for Notify the head of the household, the property and the fire department of the disaster information by phone, text message, network, etc.

Described siren is a plurality of, and the sound of the siren of each signal is different.

The beneficial effects of the present invention are: the present invention utilizes the data obtained by the processor to process and judge whether there is abnormality and the type of abnormality, and when the environmental change value exceeds a certain range, an alarm is issued, if the environmental change value does not develop, the alarm is stopped, if If the rate of change continues to accelerate, the actuator is controlled to take measures, and the early warning module is controlled to give an alarm. Therefore, the interference of environmental temperature, humidity and other factors is reduced, the reliability and stability of the system are greatly improved, the false alarm rate is reduced, and the use is convenient and the maintenance cost is low.
