Description

Fire warning system with emergency fire power supply

The invention relates to a fire warning system, in particular to a fire warning system with an emergency fire power supply.

In recent years, the concept of fire safety has been increasing in the daily life of Chinese people. Fire safety equipment can be said to be an important equipment for safeguarding the lives and property of Chinese people, especially in public places such as office buildings, stations, and department stores. In addition, the fire emergency broadcasting system plays a very important role in maintaining the safety of the public. In recent years, the installation of fire-fighting broadcasting systems in buildings has been basically a basic requirement, and if a failure occurs, it will be difficult to be discovered and pose a potential danger. Among them, for emergency equipment for firefighting, unlike the broadcasting equipment for general business, it is required to publish the equipment specification according to the fire department, conduct testing and certification of the form, structure, material and performance of the relevant equipment, and issue a report. Finally, it is certified by the fire department. Qualified and strict quality control system is the goal, as one of the purposes of ensuring safety.

In the entire fire emergency broadcast system, the emergency power supply plays a role like a heart in the human body in the event of a fire. In the event of a fire that causes the mains to be interrupted, the emergency power supply is generally only required to meet the fire protection regulations. "In the event of a fire, the emergency broadcast system needs to continue to report more than ten minutes," to alert the public to the basic escape and evacuation time.

However, each group of horn circuits of the general emergency power supply will be included in the main control room related audio equipment and the speakers installed in the field, wherein the most power consuming is to promote the amplifier of each circuit horn, in each group of battery capacity The design principle will be based on the power consumed by each set of horn circuits in the emergency situation when the warning broadcast is broadcast for ten minutes. Because the battery is expensive and doubles with the battery capacity, the battery pack is considered under cost considerations. The selection often does not design too much capacity, as long as a single battery pack is sufficient to ensure the energy of a single speaker loop, but the emergency power supply designed from this point of view will have a fatal crisis, because the fire emergency broadcast system is "suspected" in the area. When the fire alarm occurs, an emergency broadcast broadcast will be carried out. Once the battery pack design capacity is selected to be insufficient, the battery pack in the area where the fire is supplied will be over-consumed when the "suspected" fire alarm occurs, waiting for confirmation to be confirmed as a fire. When the whole area broadcasts, the battery pack in the fire point area cannot provide the speaker back. Sufficient power, because it is impossible to estimate the fire point area, the general approach is to increase the battery capacity according to the budget of each manufacturer, but it will also greatly increase the cost, and excessive battery use will also cause unnecessary environmental pollution. And the choices depend on the budget of each manufacturer and the equipment used on site.

Accordingly, the main object of the present invention is to provide a fire warning system with an emergency fire power supply for utilizing an emergency fire power supply when the power detector performs residual power measurement on the battery or when the remaining battery power is insufficient. Power is given to the corresponding warning device.

A fire warning system with an emergency fire power supply system includes a plurality of warning circuits, an emergency fire power supply, and a second switch; each of the warning circuits includes at least one alarm, a battery, and a power detector And a first switch; the power detector has a discharge test resistor; the first switch-on relationship is electrically coupled to the battery, and is electrically coupled to the alerter and the power detector. When the first switch is coupled to the alarm, the battery provides the power of the alarm. When the first switch is coupled to the power detector, the battery is tested for the discharge test. Discharging for the power detector to detect the remaining power of the battery; the second switch-on relationship is electrically coupled to the backup battery, and is switchably electrically coupled to the alerter in the alert circuits, and the communication coupling The power detector connected to the warning circuits; wherein the first switch in one of the warning circuits is electrically coupled to the power detector And when the power detector in one of the warning circuits detects that the remaining power of the battery is lower than a safe power, the second switch-on relationship is coupled to the occurrence of the situation. The warning device in the warning circuit is provided to provide an emergency backup power to the warning device.

In a preferred embodiment of the invention, the alerter is an audible alert and has an amplifier.

The specific embodiments of the present invention will be further described by the following examples and drawings.

The invention relates to a fire warning system, in particular to a fire warning system with an emergency fire power supply. The invention is illustrated by the following description of the preferred embodiments of the invention, and is not intended to limit the invention. The contents of this preferred embodiment are detailed below.

Please refer to the first figure and the second figure. The first picture is a schematic diagram of the emergency fire power supply supplying power to the warning device, and the second figure is the schematic diagram of supplying the emergency fire power supply to the other warning device. The present invention discloses a fire warning system having an emergency fire power supply 12 that includes a plurality of warning circuits 11a, 11b, and 11c, and an emergency fire power supply 12 and a second changeover switch 13.

Each of the warning circuits 11a, 11b, and 11c includes at least an alerter 111a, 111b, and 111c, a battery 112a, 112b, and 112c, a power detector 113a, 113b, and 113c, and a first switch 114a, 114b, and 114c. The alarms 111a, 111b, and 111c may be audible alarms, for example, may include a broadcast host, an amplifier, and a horn. Further, the indicators 111a, 111b, and 111c may also be light warnings, but the alarms 111a, 111b, and 111c. The form is not the location of the technology in this case, so there is no limit.

The power detectors 113a, 113b, and 113c have a discharge test resistors 1131a, 1131b, and 1131c for testing the remaining power of the batteries 112a, 112b, and 112c, since the discharge test resistors 1131a, 1131b, and 1131c are in the test batteries 112a, 112b. When the remaining power of 112c is used, the batteries 112a, 112b, and 112c can be simulated in the discharge state during operation, so that the power remaining in the batteries 112a, 112b, and 112c can be accurately tested.

The first switching switches 114a, 114b and 114c are electrically connected to the batteries 112a, 112b and 112c, and are electrically coupled to the alarms 111a, 111b and 111c. The power detectors 113a, 113b and 113c are electrically switchable. For example, in the first figure, when the first switch 114b, 114c is coupled to the indicators 111b, 111c, the batteries 112b, 112c provide the powers P1 and P2 of the indicators 111b, 111c. When the first switch 114a is coupled to the power detector 113a, the battery 112a releases the power P3 to the discharge test resistor 1131a for the power detector 113a to detect the remaining power of the battery 112a.

The second switch 13 is electrically connected to the emergency fire power source 12, and is electrically coupled to the alarms 111a, 111b, and 111c in the warning circuits 11a, 11b, and 11c, and is communicatively coupled thereto. For example, in the first diagram, when the first switching switch 114a is coupled to the power detector 113a, the second switching switch is used in the first circuit breakers 113a, 11b, and 11c. The switch is electrically coupled to the alerter 111a in the alert circuit 11a to supply the power P4 to the alerter 111a when the power detector 113a tests the remaining power of the battery 112a.

When the power detector 113a tests the remaining power of the battery 112a and determines that the remaining power of the battery 112a is higher than a safe power, the first switch 114a can be switched and electrically connected to the alerter 111a as shown in the second figure. So that the battery 112a normally supplies the power P5 to the alarm, and the first changeover switch 114b is switched to the power detector 113b, and the power supply detector 113b tests the remaining power of the battery 112b. At the same time, the second changeover switch 13 is switched to be connected to the alerter 111b to provide the power P6 to the alerter 111b.

Wherein, when the power detectors 113a, 113b, and 113c in one of the warning circuits 11a, 11b, and 11c detect that the remaining power of the batteries 112a, 112b, and 112c is lower than the safety power, the second switch 13 That is, the alarms 111a, 111b, and 111c in the warning circuits 11a, 11b, and 11c in which the situation occurs are coupled to provide the emergency backup power of the alarm.

It can be clearly seen that the present invention utilizes power detectors 113a, 113b and 113c having discharge test resistors 1131a, 1131b and 1131c to achieve the most suitable battery conditions 112a, 112b and 112c, compared to conventional fire broadcast systems. The remaining power test is performed, and the alarms 111a, 111b, and 111c are supplied with power by the emergency fire power supply 12 during the test, and further, when it is determined that the surplus power of any of the batteries 112a, 112b, and 112c is insufficient, that is, the emergency fire power supply 12 The alarms 111a, 111b, and 111c corresponding to the batteries 112a, 112b, and 112c are supplied with electric power, thereby enabling more accurate measurement and a safer power supply mode, and the battery 112a in each of the warning circuits 11a, 11b, and 11c. The capacity of 112b and 112c does not need to be deliberately increased, and the manufacturing cost can be reduced.

Further, when more than one of the storage batteries 112a, 112b, and 112c is determined to have insufficient remaining power, the second changeover switch 13 may alternately switch to the alerter 111a corresponding to the batteries 112a, 112b, and 112c having insufficient remaining power. , 111b and 111c, intermittently providing the power of the alarms 111a, 111b and 111c, and the time of the switching can be designed according to the actual situation, for example, when it is necessary to provide three or less of the warning devices 111a, 111b and 111c in turn. It can be switched once every ten seconds. If there are more than three warning devices 111a, 111b and 111c, it will be switched once every five seconds to avoid the interval of warnings being too long.

The features and spirit of the present invention will be more apparent from the detailed description of the preferred embodiments. On the contrary, the intention is to cover various modifications and equivalents within the scope of the invention as claimed.
