When smoke is detected in the room where the vessel is located, an alarm sound can be emitted to promptly evacuate personnel in the room.

  The conventional smoke alarm generates a fire alarm when indoor smoke is detected, but since the detected location is only the room where the smoke alarm is located, the smoke concentration in the room away from the fire source However, if the smoke alarm in the room is not high enough to operate, when the alarm is delayed and a fire occurs in a room in the same building, the surrounding rooms Cannot notify the alarm.

  However, current smoke alarms are usually used independently, and only when the smoke concentration exceeds a predetermined value, the smoke alarm is installed in a room away from the fire source. Even if installed, an alarm cannot be issued early. For this reason, the present invention is provided with means for issuing an alarm in conjunction with the smoke alarm device, so that the effect of early warning of a fire is achieved.

  For the above purpose, the present invention provides a kind of interlocking smoke alarm, which includes a main body, a wireless transmission module, a smoke detection means and an alarm unit respectively installed in the main body. , Of which:

  The present invention also combines a plurality of interlocking smoke alarms as a single interlocking smoke alarm system. In this interlocking smoke alarm system, a plurality of the interlock smoke alarms described above are installed in a building, and the other smoke alarms received by the wireless transmission module of each interlock smoke alarm are When the intensity of the alarm signal to be output exceeds the predetermined signal threshold, the alarm unit is driven to issue an alarm, and at least within the signal cover range of the alarm signal output by each interlocking smoke alarm device, The intensity of the alarm signal received by one interlocking smoke alarm exceeds the predetermined signal threshold.

  Further, each of the wireless transmission modules of the present invention includes a control device and a wireless transceiver electrically connected to the control device, and each of the smoke sensing means and each of the alarm units is connected to each of the control devices. Electrically connected.

  Further, each smoke sensing means of the present invention is an ionized smoke sensing means or a photoelectric smoke sensing means.

  Preferably, each alarm unit of the present invention is a buzzer.

  When using the present invention, install multiple interlocking smoke alarms of the present invention in multiple rooms of the building, and when each interlocking smoke alarm senses smoke, it will alarm together with the surrounding interlocking smoke alarms So that the intensity of the alarm signal received by at least one of the interlocking smoke alarms exceeds the predetermined signal threshold within a signal cover range of the alarm signal output by each interlocking smoke alarm. In this way, when a fire occurs in a room in the building, the present invention in the room senses smoke and issues an alarm, and outputs an alarm signal to the outside, away from the fire source. An interlocking smoke alarm in the surrounding room can receive the alarm signal and issue an alarm together with the interlocking smoke alarm at the fire source.

  As an effect of the present invention, the wireless transmission module is designed to output an alarm signal to the outside, and when each interlocking smoke alarm device receives the alarm signal, the wireless transmission module is designed to issue an alarm according to a result of comparison with a predetermined signal threshold. Therefore, when operating multiple devices of the present invention, the interlocked smoke alarm close to the fire source generates an alarm, so the range of the alarm is expanded to the outside, and the interlocked smoke alarm where the smoke has not yet reached is also an alarm signal By receiving the warning, it becomes possible to issue a warning early, and the effect of increasing the evacuation time of personnel can be demonstrated by the early warning.

  In order that the technical features and practical effects of the present invention can be clearly understood and implemented based on the contents of the specification, the present invention will be described in detail as follows with preferred embodiments shown in the drawings.

  Referring to the preferred embodiments of the present invention shown in FIGS. 1 to 3, the interlock smoke alarm provided by the present invention includes a main body 10 and a wireless transmission module 11 installed in the main body 10, respectively. Including smoke sensing means 12 and alarm unit 13, of which:

  The wireless transmission module 11 includes a control device 111 and a wireless transceiver 112 electrically connected to the control device 111, and the control device 111 may be a single chip or a micro control unit (MCU), The wireless transceiver 112 may be a WIFI wireless transceiver, a Bluetooth wireless transceiver, or a radio transceiver of other frequency, and the wireless transceiver 112 of the wireless transmission module 11 continuously senses an alarm signal, and the wireless transmission module 11 The control device 111 is set with a signal threshold value for comparison with the alarm signal received by the wireless transceiver 112.

  The smoke detection means 12 and the alarm unit 13 are electrically connected to the control device 111 of the wireless transmission module 11, respectively. The smoke detection means 12 is an ionization smoke detection means, a photoelectric smoke detection means or an ionization type. The alarm unit 13 is an element that warns by sound or flash, such as a buzzer or a flashlight, and the alarm unit 13 is controlled by a command from the control device 111. It can be driven by the sensing result of the sensing means 12.

  Referring to the flowchart of FIG. 2, when the smoke detecting means 12 detects smoke, the detection result is transmitted to the control device 111, and the control device 111 causes the alarm unit 13 called buzzer or flashlight to be turned on. To drive. At the same time, the control device 111 causes the wireless transceiver 112 to output the alarm signal to the outside, and the intensity of the alarm signal is expanded to a certain range around the wireless transceiver 112. Referring to the flowchart of FIG. 3, when the wireless transceiver 112 receives the warning signal, the control device 111 compares the intensity of the warning signal received by the wireless transceiver 112 with the predetermined signal threshold. When the intensity of the received alarm signal exceeds the predetermined signal threshold, the control device 111 drives the alarm unit 13 to issue an alarm.

  That is, when two or more interlocking smoke alarms are used, even if there are a plurality of interlocking smoke alarms within the range of the alarm signal output by one interlocking smoke alarm. Only the interlocking smoke alarm device in which the intensity of the received alarm signal exceeds the signal threshold value of the alarm device itself is interlocked to issue an alarm together with the interlocking smoke alarm device that detects smoke. That is, the present invention can control the interlocking effective range in which one interlocking smoke alarm device and another interlocking smoke alarm device issue an alarm by increasing or decreasing the signal threshold set in each control device 111. it can.

  The present invention also combines a plurality of interlocking smoke alarms as a single interlocking smoke alarm system. As shown in FIG. 4, four interlocking smoke alarms A are installed in one building X, and are installed in four rooms Y in the building X, respectively. When one of the interlocking smoke alarms A detects smoke generated in a fire, the interlocking smoke alarm A itself outputs an alarm signal in addition to issuing an alarm, and the alarm signal signal cover Range C covers all other interlocking smoke alarms A, but only the two interlocking smoke alarms A that are closer to the smoke sensing alarm A that senses smoke are linked effective range B ( Since the intensity of the received alarm signal is within a range exceeding the predetermined signal threshold), only the two interlocking smoke alarm devices A are interlocked to issue an alarm.

  The purpose of the system of the present invention is to compare the intensity of an alarm signal with a predetermined signal threshold, and the interlocking smoke alarm A in a situation where it cannot detect a diffused smoke and cannot issue an alarm, Since the alarm can be issued in conjunction with the alarm signal output from the device A, the range where the system combining two or more interlocking smoke alarm devices A can output an alarm is further increased from the point where smoke can be detected. To a predetermined distance (interlocking effective range B). As the fire spreads and smoke spreads, the alarm range is further increased, and the alarm range covered by multiple interlocking smoke alarms A is not limited to the flat floor, but the interlocking smoke installed on the upper and lower floors. Alarm A can also be covered. For the above purpose, when the present invention assembles a system with a plurality of interlocking smoke alarms A, at least one interlocking smoke alarm is within the signal cover range C of the alarm signal output by each interlocking smoke alarm A. The intensity of the warning signal received by the device A needs to exceed the predetermined signal threshold.
