Abstract

This new creation is about a simple fire on / off system, which is mainly when one of the two fire detectors detects a fire alarm, it will first start a buzzer to warn people in the room to pay attention or escape. When the fire detector detects a fire alarm, in addition to the two buzzers will start to sing, the control unit will automatically determine that a fire alarm has started in the room, then start the power-off and fire extinguishing function, and first turn on the smoke exhaust unit to discharge the indoor gas. To avoid the danger of lack of oxygen or toxic gases in the room, then control the power-on and power-off unit to make the load power supply network into a power-off state to avoid dangers such as wire fire or electric shock during fire extinguishing, and then start the emergency lighting unit and sprinkle. The water unit is operated in order to effectively extinguish the fire at the first time and provide effective escape for internal personnel. When the control unit judges that the fire situation is resolved, it will start the power recovery function, and control the smoke exhaust unit, sprinkler unit, emergency lighting unit to stop operating, and drive the power on and off unit to make the load power supply network form a power-on state.

Description

Simple fire on / off system

This creation is about a fire prevention system, especially a simple fire on / off system.

In recent years, residential fires have occurred frequently, and their hazards have expanded to public safety. It is difficult to detect fires in the early stages of the fire. When they are found, the fire has often spread to escapes that cannot be responded to in time. In view of this, the fire department strongly promotes "residential fire alarms", but because it can only function as a tweet at the time of a disaster to notify emergency evacuation of personnel in the room, it fails to achieve the first-time self-help disaster relief function and extension. The escape time of personnel makes the effect still insufficient.

In order to avoid disasters caused by fires, most people tend to prevent them beforehand, mainly through automatic power-off systems. When conditions are met, they automatically respond to power-offs to avoid excessive current caused by fires, such as installing power outages inside plug extension cables System, or power outage system in the distribution box. However, such prior precautionary construction is expensive and must be installed for each load, making it difficult to install during construction and expensive in cost. Furthermore, this kind of ex ante prevention can only deal with the fire caused by the load due to the excessive current, but cannot effectively deal with the fire caused by other situations (such as the fire spreading to the house next door).

Although someone has designed an automatic sprinkler system for post-event prevention and control, the sprinkler function can be automatically activated when a fire occurs, in order to extinguish the fire as soon as possible, or to delay the spread of the fire to help internal personnel have enough time to escape. However, this kind of after-the-fact prevention is inadequate: when the fire is extinguished, because the indoor load power supply network is still in the state of power supply conduction, the fire dampening electrical appliances often cause secondary disasters, in addition to causing leakage and fire, Fire water on the ground also poses a risk of electric shock to rescuers or escapees.

At this point, the creator of this new type, based on his own professional knowledge, believes that the aforementioned post-mortem prevention really needs to be improved, and starts to think about the solution.

In view of the deficiencies described in the prior art, the creator of the new type proposes a solution, which is about a simple fire on / off system, including:

One smoke unit:

The smoke exhaust unit is mainly used for setting an air outlet in the first room for discharging the smoke in the first room.

A fire detector group:

The fire detector set is provided for installation in the first room. The fire detector set includes a first fire detector electrically connected to the first buzzer and a second fire detector electrically connected to the second buzzer. A second fire detector, the first fire detector may be used to control the activation of the first buzzer when the detected result value is higher than a first threshold value, and when the detected result value falls from the first threshold value The first buzzer is turned off when it is below a second threshold; the second fire detector can be used to control the second buzzer to start when the detected result value is higher than a first threshold, and when the detected The second buzzer is turned off when the result value falls below the second threshold from the first threshold.

One sprinkler unit:

The sprinkler unit is installed in the first room.

An emergency lighting unit:

The emergency lighting unit is installed in the first room.

One on and off unit:

The on / off unit is provided at the beginning of the load power supply network installed in the power distribution box, and the on / off unit is used to form the load power supply network to be powered on or off.

A control unit:

The control unit is electrically connected to the smoke exhaust unit, the fire detector group, and the sprinkler unit, respectively. , The emergency lighting unit, and the power on and off unit, the control unit has a disaster prevention function and a power recovery function; the disaster prevention function can be performed by the control unit: when the first buzzer and the second buzzer When starting up, first control the smoke exhaust unit to operate, and then control the power on and off unit to operate after a preset time interval, so that the load power supply network can form a power outage, and start the emergency lighting unit and the sprinkler unit. ; The resumption function can be performed by the control unit: when the first buzzer and the second buzzer are switched from the activated state to the closed state, the smoke exhaust unit, the sprinkler unit, and the emergency lighting are controlled The unit stops operating and controls the on-off unit to operate so that the load power supply network can be energized.

In order to reduce the misjudgment of machinery, this new creation specially sets two fire detectors. When one of the first fire detector or the second fire detector detects a suspected fire condition, only the corresponding fire A buzzer or the second buzzer is activated to remind the insiders to increase alertness and attention; and when both the first buzzer and the second buzzer are activated at the same time, it is determined that a fire has occurred. The control unit starts the follow-up actions. First, the smoke exhaust unit is started to avoid the accumulation of smoke and dust in the room, which will cause the dangers of oxygen depletion, oxygen depletion, and other toxic gases. Then, the load power supply network will be cut off to avoid electrical fire or During the fire extinguishing process, a second-degree hazard was caused by electric shock and other problems. At the same time, the sprinkler function and emergency lighting function were automatically activated to extinguish the fire or prolong the escape time of indoor personnel at the first time, and provide sufficient light sources to assist indoor personnel in emergency. Escape; if the first buzzer and the second buzzer are stopped after the fire is extinguished, the control unit will automatically control the load for Formation of the conductive network, while closing the sprinkler unit, the emergency lighting unit, and said exhaust means, so that the indoor rehabilitation staff.

In summary, this creation has the functions of automatic fire extinguishing, automatic power failure, and automatic power restoration, and is easy to install. It does not need to significantly change the power supply network inside the room. It is mainly for installing the on / off unit in the power distribution box. Simple and low installation cost.

This allows the system to notify police personnel as soon as possible when a fire alarm is determined to greatly reduce the loss of life and property caused by the fire.

In order to reduce the misjudgment of the machine, this creation specially sets two fire detectors (21, 22) in the first room. When one of the fire detectors (21or22) detects a suspected fire condition, it corresponds to the first fire detector. A buzzer (23) or the second buzzer (24) starts to tweet to remind the insiders to increase alertness and attention. When the two fire detectors (21, 22) both detect the occurrence of a fire condition, the first buzzer (23) and the second buzzer (24) both sing, and the control unit (6) It will automatically determine that there is a fire and start the subsequent actions. Among them, it is worth mentioning that the detection results of each fire detector (21, 22) can be sent to the control unit (6) and each buzzer (23, 24) by electronic signals for the control After the unit receives the electronic signal, it starts the follow-up workflow according to the design of the program software.
