Furthermore, the wireless transmission module of the present invention comprises a controller and a transceiver electrically connected to the controller, wherein the smoke detection structure and the alarm element are electrically connected to the controller respectively.
Furthermore, the smoke detection structure of the present invention is an ion type smoke detection structure or a photoelectric type smoke detection structure.
Preferably, the alarm element of the present invention is a buzzer.
The invention also provides a linked smoke alarm system consisting of a plurality of linked smoke alarms, wherein a plurality of linked smoke alarms are arranged in a building, when the intensity of alarm signals received by the wireless transmission module of each linked smoke alarm and sent by other linked smoke alarms is greater than a preset signal threshold value, an alarm element is driven to send out an alarm, and in the receiving range of the alarm signals sent by each linked smoke alarm, the intensity of at least one linked smoke alarm receiving the alarm signals is greater than the preset signal threshold value.
Furthermore, each wireless transmission module of the present invention includes a controller and a transceiver electrically connected to the controller, and each smoke detection structure and each alarm element are electrically connected to each controller respectively.
Furthermore, each smoke detection structure of the present invention is an ion-type smoke detection structure or a photoelectric-type smoke detection structure.
Preferably, each of the alarm elements of the present invention is a buzzer.
When the smoke alarm is used, the plurality of linked smoke alarms are respectively arranged in a plurality of rooms of a building, and in order to enable each linked smoke alarm to detect smoke, the linked smoke alarms around can be linked to send out an alarm together, in the receiving range of the alarm signal sent by each linked smoke alarm, the intensity of the alarm signal received by at least one linked smoke alarm is larger than the preset signal threshold value, so when one room in the building is on fire, the smoke alarm is sent out when the smoke alarm is detected in the room, the smoke alarm simultaneously sends out an alarm signal outwards, and the linked smoke alarms in other rooms far away from the fire point around receive the alarm signal and send out an alarm together with the linked smoke alarms at the fire point.
The invention has the advantages that the design that the wireless transmission module can send out alarm signals outwards and each linkage smoke alarm can be compared with the preset signal threshold value after receiving the alarm signals to send out alarms, so that when a plurality of the invention are applied, the alarm range can be expanded outwards in a mode that the linkage smoke alarms close to the fire are used for sending out alarms, the linkage smoke alarms at the positions where smoke does not reach can send out alarms in advance in a mode of receiving the alarm signals, and the effect of early warning and increasing the escape time of people is achieved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The invention is described in further detail below with reference to the attached drawing figures:
referring to fig. 1 to 3, the present invention provides a linkage smoke alarm, which includes a body 10, and a wireless transmission module 11, a smoke detection structure 12 and an alarm device 13 respectively disposed on the body 10, wherein:
the wireless transmission module 11 includes a controller 111 and a wireless transceiver 112 electrically connected to the controller 111, the controller 111 may be a single chip or a Microcontroller (MCU), the wireless transceiver 112 may be a WIFI wireless transceiver, a bluetooth wireless transceiver or a transceiver of other frequency radio waves, the wireless transceiver 112 of the wireless transmission module 11 continuously detects an alarm signal, and the controller 111 of the wireless transmission module 11 sets a predetermined signal threshold for comparing the alarm signal received by the wireless transceiver 112.
The smoke detection structure 12 and the alarm element 13 are electrically connected to the controller 111 of the wireless transmission module 11, respectively, the smoke detection structure 12 may be an ion type smoke detection structure, a photoelectric type smoke detection structure, or an ion and photoelectric composite type detection structure, the alarm element 13 may be a buzzer or a flash lamp, and the alarm element 13 may be driven by the detection result of the smoke detection structure 12 through a command of the controller 111.
Referring to the flowchart of fig. 2, when the smoke detection structure 12 detects smoke, the detection result is transmitted to the controller 111, so that the controller 111 drives the alarm element 13, that is, the buzzer or the flashlight gives an alarm, and the controller 111 causes the wireless transceiver 112 to send an alarm signal outwards, wherein the intensity of the alarm signal covers a range extending from the wireless transceiver 112 to the periphery, and please refer to the flowchart of fig. 3, when the wireless transceiver 112 receives the alarm signal, the controller 111 compares the intensity of the alarm signal received by the wireless transceiver 112 with a predetermined signal threshold, and if the intensity of the received alarm signal is greater than the predetermined signal threshold, the controller 111 drives the alarm element 13 to send an alarm.
That is, when more than two interlocked smoke alarms are used, even if the other interlocked smoke alarms are all located within the range covered by the alarm signal sent by one of the interlocked smoke alarms, only the interlocked smoke alarms having the signal intensity of the received alarm signal larger than the predetermined signal threshold value thereof are interlocked to send out an alarm together with the interlocked smoke alarms which detect smoke. The present invention can control the linkage effective range of one linkage smoke alarm to link other linkage smoke alarms to give an alarm by increasing or decreasing the predetermined threshold set in each controller 111.
The present invention can form a linkage smoke alarm system by a plurality of linkage smoke alarms, as shown in fig. 4, four linkage smoke alarms a are arranged in a building X, the plurality of linkage smoke alarms a are respectively arranged in four different rooms Y in the building X, wherein one linkage smoke alarm a detects smoke generated by flame combustion, the linkage smoke alarm a sends out an alarm signal except for sending out an alarm itself, a signal coverage range C of the alarm signal includes all the other linkage smoke alarms a, but only two linkage smoke alarms a which are closer to the linkage smoke alarm a which detects smoke are located in a linkage effective range B (a range in which the intensity of the received alarm signal is higher than a predetermined signal threshold), and thus the two linkage smoke alarms a are sent out in a linkage manner.
The system of the invention is used for comparing the intensity of the alarm signal with the preset signal threshold value, when some linkage smoke alarms A can not detect diffused smoke to send out alarm, the alarm signal sent by the peripheral linkage smoke alarms A can be linked to send out alarm together, so that the linkage smoke alarms A of more than two or more composition systems can send out alarm range, the alarm range expanded by the linkage smoke alarms A is not limited to a plane floor, and the linkage smoke alarms A arranged on different floors are covered.
