Abstract
The utility model discloses a synchronous frequency, broadcasting and wireless speaking optical cable relay system. A base station comprises a synchronous frequency, broadcasting and wireless speaking relay station, a base station optical transmitter and receiver, a system optical transmitter and receiver, a base station switch and a scheduling system switch interface. The base station switch is electrically connected with a scheduling switch. The system optical transmitter and receiver is connected with the base station optical transmitter and receiver through a fiber. The synchronous frequency, broadcasting and wireless speaking relay station is electrically connected with the base station optical transmitter and receiver. The system optical transmitter and receiver is electrically connected the base station switch. The capacity of the system base station is determined based on requirements of a user. The synchronous frequency, broadcasting and wireless speaking relay system is suitable for tunnels, mines, highways, police systems, property management departments with underground parking lots and underground multi-layer buildings. Only a pair of frequency points is needed for a frequency, so that if any user within the system initiates calling, called users within a net can simultaneously receive the calling 30 milliseconds later. In addition, identical frequency signals among base stations can repeatedly cover 10-30% without affecting normal conversation, and an interphone PPT system is loosened after a sentence is finished and then is automatically off line within 30 milliseconds, so that an effective coverage rate reaches more than 98% and a call completion ratio is more than 98%. The relay system of the utility model truly covers all areas under all weather conditions, can respond immediately once demands are made, and is capable of scheduling at a high speed.
Description
Technical field
The utility model relates to communication system, specifically is meant a kind of base station of setting up with optical cable coupling part device.
Background technology
Three with relay system be with frequently, with broadcast, synchronous radio intercommunication Optical fiber relay system, be with frequently, with broadcasting the optimization and upgrading version.With frequently: many trunk desks use same frequency emission, and signal repeats to cover 10～30% between the base station does not influence normal talking.Reach the round-the-clock omnidistance purpose that covers.Synchronously: relay the automatic and main broadcaster's trunk desk clock synchronization of trunk desk, do not need the GPS time service, set up the common-frequency simulcasting net of low-cost high-efficiency.With broadcasting: any one user makes a call in the net, and system chooses receives that the stronger trunk desk of signal makes other trunk desk of main broadcaster's trunk desk and relay the audio signal of main broadcaster's trunk desk simultaneously, thereby effectively avoids many through disturbing.Realize adaptation function, reach installation, the purpose very easily of debugging, upgrade.Exist between the present trunk desk information can not share, with phase mutual interference between frequently, problem such as can not seamlessly cover, and in 30 milliseconds, can not exhale all users of logical working site, many base stations.
The utility model content
Given this, the purpose of the utility model is to provide a kind of three with the optical cable relay system, but intrasystem trunk desk information sharing, with non-interference between frequently, realized seamless covering.
To achieve these goals; The technical scheme that the utility model adopted is: the base station comprises one three same trunk desk, a stylobate station optical transceiver, system's optical transceiver; An interface on one stylobate station switch, the dispatching patcher switch; The interface of base station exchange machine and scheduling switch is electrically connected, and system's optical transceiver is connected through optical fiber with the base station optical transceiver, and three with trunk desk and the electrical connection of base station optical transceiver; System's optical transceiver is connected with base station exchange is dynamo-electric.
Further, a video camera is electrically connected with the base station optical transceiver.
Further, a telephone set is electrically connected with the base station optical transceiver.
The beneficial effect of the utility model is: these three same relay systems; Be applicable to tunnel, tunnel, mine, highway, public security system, the property that the underground parking is arranged and underground tier building; Frequency is only used a channel, reaches that any one user makes a call in the system, and the called subscribers after 30 milliseconds in the net can receive simultaneously; Effective coverage rate is reached more than 98%, and call completion ratio is more than 98%.Accomplish that really round-the-clock, non-blind area covers, and reaches the purpose of getting ready to go into action in hundreds, dispatching at a high speed.
Description of drawings
The enforcement illustration of Fig. 1 the utility model.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and execution mode.
Please refer to shown in Figure 1; Three same scheduling switches 1 are System Control Centers; Can be installed in ground such as control room, three with four three same base stations of scheduling switches 1 control, and wherein each base station needs one three with trunk desk 2, a stylobate station switch 3, a stylobate station optical transceiver 4, system's optical transceiver 5; Wherein, Base station exchange machine 3 and three is electrically connected through cable with the interfaces of scheduling on the switches 1, and system's optical transceiver 5 is electrically connected with base station exchange machine 3, and system's optical transceiver 5 and base station optical transceiver 4 are connected through optical fiber.Three are installed in the base station with trunk desk 2, base station optical transceiver 4, and system's optical transceiver 5, base station exchange machine 3, scheduling switch 1 are installed in the control room.
Also can connect video camera 6 on the base station optical transceiver 4, carry out timing monitoring.
Base station optical transceiver 4 can also be electrically connected with a landline telephone 7.
Intercom and three is with adopting wireless connections between trunk desk 2, intercom and the intercom, and three is the DA compatibility type with trunk desk.
Adopt above-mentioned networking mode, when using in the zone, can reach the purpose of getting ready to go into action in hundreds, dispatching at a high speed, whole system exhales the logical time less than 30ms, and call completion ratio is more than 98%, and area coverage reaches more than 98%.Four general a pair of frequencies in base station, signal allows to repeat to cover 10～30% between the base station.Like the need dilatation, only need three of the more interfaces of replacing to dispatch switch together and get final product.
The above; Be merely several kinds of preferable embodiments of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range of claim.
