Description
Technical field
The utility model relates to a kind of broadcast system, particularly a kind of high building fire fighting emergency broadcast system that is integrated with communication transfer module repeater.
Background technology
Flourish along with socio-economic activity, in population, constantly upwards under the limited situation of soaring and land resource, the story height of building is more and more high, and therefore the fire alarm system in building is not only indispensable and most important.
Existing fire broadcast system, mainly comprises fire-fighting urgent broadcast main frame, multiple loud speaker that is installed on respectively the each floor of building appropriate location.Each loud speaker is to be electrically connected by a power line and a signal line and fire-fighting urgent broadcast main frame.Based on this, after this fire-fighting urgent broadcast main frame receives arbitrary floor and occurs as fire-fighting signals such as fire, can order about immediately suitable loud speaker and carry out fire broadcast, personnel in building can be escaped as early as possible.There are the following problems for it: loud speaker is installed on respectively the zones of different of each floor of building, indoor, the corridor of such as each resident family, each public space etc., and each loud speaker is all to utilize a power line and a signal line and fire-fighting urgent broadcast main frame to be electrically connected, so that the usage quantity of these power lines and this signal line is many, and the higher required line length of floor is longer, line construction is very complicated, constructs consuming time.In addition, based on the consideration to load, general power line and the signal line using is expensive cable, number of, lines the more and length longer, line cost is larger.
Summary of the invention
The purpose of this utility model is for a kind of high building fire fighting emergency broadcast system of being convenient to monitoring, circuit simplification, facilitating communication test and urgent broadcast is provided.
The technical solution of the utility model is:
A kind of high building fire fighting emergency broadcast system, comprise fire-fighting urgent broadcast main frame, multiple loud speakers that are installed on respectively the each floor of building, its special character is: the described loud speaker of each floor is electrically connected with respectively a repeater that is preset with exclusive code, described fire-fighting urgent broadcast main frame is by urgent broadcast main controller, and respectively with the DC power supply of its electric connection, power amplifier, communication module group, loud speaker subregion control panel and monitoring loudspeaker composition, described power amplifier output is connected with two broadcast main lines, the described repeater of multiple floors is in parallel in TW two wire mode and be electrically connected on two described broadcast main lines respectively, the output of described communication module group is connected with two communication main lines, the described repeater of multiple floors is in parallel in TW two wire mode and be electrically connected on two described communication main lines respectively.
The beneficial effects of the utility model are:
1, the speech conversion that this fire-fighting urgent broadcast main frame can be inputted the external world becomes speech sound signal, while transmitting this speech sound signal, can add a prescribed coding signal simultaneously, this speech sound signal and prescribed coding signal transfer to each repeater by broadcast main line, after these repeater decodings, in the time that prescribed coding signal that wherein a repeater receives is consistent with its default exclusive code, this repeater can transfer to coupled loud speaker so that it broadcasts by this speech sound signal.
2, whether this fire-fighting urgent broadcast main frame can also be exported a communication test signal and transfer to each repeater by communication main line unimpeded with detection line.
3, when respectively electrical overload appears in this loud speaker, respectively this repeater can make circuit be off state, and respectively the broadcast situation of this loud speaker, communication test situation and electrical overload situation all can feedbacks and be presented on loud speaker subregion control panel, are convenient to monitoring.
4, only need set up two broadcast main lines and two communication main lines, the repeater that is installed on zones of different just can be connected to this broadcast main line and this communication main line by shorter and more cheap parallel line, not only can alleviate the burden of bracing wire operation, and overall circuit simplified and reduced line cost, and can be convenient to communication test.Meanwhile, the electronic overload that can also avoid fire-fighting urgent broadcast main frame to be subject to each loud speaker due to the setting of repeater affects the situation being damaged.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, this high building fire fighting emergency broadcast system, comprise fire-fighting urgent broadcast main frame 1, multiple loud speakers 2 that are installed on respectively the each floor of building, the described loud speaker 2 of each floor is electrically connected with respectively a repeater 3 that is preset with exclusive code, described fire-fighting urgent broadcast main frame 1 is by urgent broadcast main controller 101, and respectively with the DC power supply 102 of its electric connection, power amplifier 103, communication module group 105, loud speaker subregion control panel 104 and monitoring loudspeaker 106 form, described power amplifier 103 outputs are connected with two broadcast main lines 5, the described repeater 3 of multiple floors is in parallel in TW two wire mode and be electrically connected on two described broadcast main lines 5 respectively, the output of described communication module group 105 is connected with two communication main lines 4, the described repeater 3 of multiple floors is in parallel in TW two wire mode and be electrically connected on two described communication main lines 4 respectively.In described repeater 3, be provided with one in the time there is electrical overload in loud speaker 2 in order to block the overload blocking circuit of circuit.
Wherein, DC power supply 102 provides direct power supply to urgent broadcast main controller 101.The electric power that power amplifier 103 transmits in order to Receiving Host be attached with the speech sound signal of prescribed coding signal, and the speech sound signal that is attached with prescribed coding signal is carried out to power amplification processing.Communication module group 105 and loud speaker subregion control panel 104 are mainly used in the respectively electrical overload situation of broadcast situation, communication test situation and each loud speaker 2 of this loud speaker 2 of monitoring.Monitor the broadcast content of loudspeaker 106 in order to the arbitrary loud speaker 2 of synchronous output.
When use, fire-fighting urgent broadcast main frame 1 is arranged on to a floor of building, multiple loud speakers 2 and repeater 3 are installed on respectively to each floor of building, broadcast main line 5 and communication main line 4 pick out rear longitudinally stretching through from fire-fighting urgent broadcast main frame 1 and are disposed at each floor, do not need to walk around all multi-obstacle avoidances in each floor, cable for connection adopts general electric wire.
