Embodiment

[0058] Such as Figure 1 to Figure 8 As shown, an implementation method of a fire telephone system includes the host calling the extension and the extension calling the host.

[0059] When the host calls the extension:

[0060] At the beginning, the fire telephone host sends inspection commands to each fire telephone extension in real time. When the fire telephone host needs to communicate with a fire telephone extension at a certain address, the fire telephone host sends a call command to the address. The fire telephone extension responds after receiving the call command from the fire telephone host, and generates ringing to remind the corresponding staff to answer the call. When the staff off-hook the fire phone extension, the fire phone extension after off-hook is separated from the base of the fire phone extension, so the circuit board inside the fire phone extension returns the off-hook command to the fire phone host after detecting the relevant signal. After the main u...

Abstract

The invention discloses an implementation method of a fire-fighting telephone system. The method comprises a host calling an extension set and the extension set calling the host. When calling the host, the extension set uploads a signal through the voice return circuit of the fire-fighting telephone extension set. And meanwhile, when the host calls the extension set, a voice signal uploaded by theextension of the fire-fighting telephone is received through the voice return circuit of the fire-fighting telephone extension set, and then the received low-level signal in the voice return circuitof the extension of the fire-fighting telephone is restored through the voice communication circuit of the fire-fighting telephone host. By means of the scheme, the purposes of being high in anti-interference capability and capable of achieving long-distance transmission are achieved, and high practical value and popularization value are achieved.

Description

technical field [0001] The invention belongs to the technical field of firefighting, and in particular relates to a method for realizing a firefighting telephone system. Background technique [0002] The fire telephone is a special equipment for fire communication. When a fire breaks out, it can provide people with convenient and fast means of communication. It is an indispensable communication equipment in the fire control and alarm system. The fire telephone is divided into a four-wire fire telephone and a bus fire telephone. The four-wire fire telephone consists of a set of power lines and a set of signal transmission lines working at the same time to realize the communication of the entire fire telephone system. The bus system fire telephone is the most commonly used fire telephone in the industry at present, that is, the communication between the fire telephone host and the fire telephone extension adopts the form of bus. The bus is not only the power line between the m...
