Problems solved by technology

However, the shortcoming of the single type is that the signals automatically sent by the fire detectors will compete with the number of fire detectors in the entire wireless fire alarm system, and it is impossible to make many fire detectors meet the specified delay requirements. Does not meet the requirements of GB4715-2005 standard
At present, the technical scheme of combining wireless radio frequency technology with independent detection and alarm technology is an important trend to promote independent detection and alarm devices. For wireless fire detectors, in order to be successfully popularized and applied, the wireless communication part should be kept in line with the detection and alarm part. The same consistent battery life, which is challenging for a good wireless alarm system with a dual communication mode

Embodiment 1

[0070] see you again Image 6 , Figure 7 As shown, the fire alarm wireless communication base of the present invention and the independent fire detector 821 with its own power supply constitute a wireless fire detector. The model of the independent fire detector specifically selected is: FSK01ZZ-S. Compulsory certification, with 1 shifting contact (passive alarm output), monitoring current 15uA and battery life of more than 5 years. The wireless communication base adopts a cylindrical shape with the same diameter as the detector, and the upper and lower shells are combined through a buckle mechanism. The interior of the wireless communication base includes a wireless communication module, an alarm input interface, an alarm playback unit, a loudspeaker, a sound chamber, a battery, a battery power detection unit, an antenna, a base shell and other components. The alarm input interface is connected to the reporting interface of the independent detector through wires, the posit...

Embodiment 2

[0102] see you again Figure 8 , Figure 9As shown, the only difference between this embodiment and Embodiment 1 is that the fire trigger device is replaced by a non-addressable manual fire alarm button 822 for an independent fire detector 821 with its own power supply, and the fire alarm wireless communication base of the present invention It forms a wireless manual fire alarm button with the non-addressable manual fire alarm button 822 . The addressable manual fire alarm button is generally connected with the wired fire alarm controller by means of bus coding. The non-addressable manual fire alarm button is a dry contact. When a manual alarm is issued, the dry contact is closed. The signal of this contact is the same as the signal of the above-mentioned transfer alarm interface. It is passively connected to the fire alarm wireless communication base. The selected manual fire alarm button is a product that has passed the national 3C compulsory certification, and has a passi...

Embodiment 3

[0105] see you again Figure 10 , Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that the wireless communication base of the present invention and the fire linkage device 81, that is, the fire audible and visual alarm 811 constitute a wireless fire audible and visual alarm. The specific selected fire sound and light alarm is a product that has passed the national type inspection and has a passive control input contact. The fire sound and light alarm has its own battery inside, and does not need a wireless base for power supply. The wireless communication base adopts a rectangular shape with the same size as the fire sound and light alarm, and the two realize the combination of the upper and lower shells through the buckle mechanism. The internal composition of the wireless communication base is the same as that of Embodiment 1. The linkage output interface is connected to the control input contact in the fire sound and light alarm through wir...

Abstract

The invention discloses a fire hazard alarm wireless communication base. The fire hazard alarm wireless communication base comprises an antenna and a base housing. The base housing is internally provided with a circuit board and an alarm playing unit. The circuit board is provided with a wireless communication module; the wireless communication module comprises an RF front transceiver, a FLASH memory, a RAM memory and an MCU control unit; and the alarm playing unit comprises a loudspeaker, a vocal chamber, and a voice integration circuit and a power amplifier circuit which are arranged on the circuit board. According to the invention, the fire hazard alarm wireless communication base has an evacuation alarm function and also has the advantages of node signal loss monitoring, low power consumption and long life work period; and through an appearance structural design, the fire hazard alarm wireless communication base can be individually combined with various independent fire hazard trigger members or fire hazard linkage devices and the like to form a wireless fire hazard alarm terminal product, and the fire hazard alarm wireless communication base is an important front part of an ideal wireless fire hazard alarm system and has a wide application value.

Description

technical field [0001] The invention relates to the field of fire alarm, and more specifically relates to a fire alarm wireless communication base. Background technique [0002] Compared with the wired fire alarm system, the wireless fire alarm system has the advantages of convenient assembly, disassembly and maintenance, and no need for wiring operations. It is especially suitable for those places that have already been built and need to install fire alarms. However, the current popularization and application of wireless fire alarm systems has some problems in system structure, product form, transmission mode, battery life, etc., and has not yet reached the mature level of wired alarm systems, which restricts its popularization and application. The details are as follows: [0003] 1) As it involves the safety of people's lives and properties, fire detection and alarm products are the earliest products that implement mandatory 3C certification in my country, and have strict ...
