Description
Technical field
The invention belongs to the mobile communication technology field, be specifically related to a kind of mobile communication system radiofrequency signal and close the device on road, especially can carry out the equipment of multisystem mixing WCDMA and TD-SCDMA signal.
Background technology
At present, pipeline equipment closes in the system that mobile communication is used, be generally that the cavity band is logical, the mixer of bandreject filtering form, simply 2 tunnel or 3 road signals are closed the road, isolation between system is not high yet, can't to tens of the present a plurality of operators' of China as many as the 2nd, 3 generation the mobile system signal close the road.And monitor data can't be provided, need the engineering staff, test to the scene with a large amount of testing equipments.Need switch base station equipment repeatedly during test, wasting manpower and material resources's financial resources are disregarded, and also easily equipment are caused damage.
Summary of the invention
Existingly to close pipeline equipment to close the road system quantity few in order to overcome, do not support 3G (Third Generation) Moblie TD time-division system, the deficiency of monitoring output etc. can't be provided, the invention provides a kind of pipeline equipment that closes, this closes the road of closing that pipeline equipment can not only be supported as many as dozens of system, the higher system isolation is provided, and supports 3G (Third Generation) Moblie TD time-division system, and the local instrument that can provide convenience detects mouth, local computer detects mouth and the remote data transmission monitoring transmits.
The technical solution adopted for the present invention to solve the technical problems is:
Adopt the cross-couplings technology, high Q value cavity band passband resistance filtering technique, and 4 close road, 5 and close roadlock resistance parallel operation technology, be engaged in technology such as directly built-in power distribution, coupling and isolator unit in the cavity, make that close the road system quantity increases to 10-12 road even more from the 2-3 road of common mixer, and, make product more common mixer product on insertion loss, stability that very large raising be arranged owing on manufacture craft, adopt the technology of unit such as built-in merit branch of while, coupling, isolation, matched load in the cavity.
The 3-G (Generation Three mobile communication system) that the present invention proposes is closed pipeline equipment, 19 inches frames with standard are installed as structural model, panel is provided with the modular connection of N-K type, be the signal input output end mouth, and the input at each road signal all is provided with a SMA-K type interface as the monitoring mouth, between this monitoring mouth and the input port 30dB coupling loss is arranged, and need not to disconnect the input port when equipment normally moves, need not to turn-off base station output, just can detect input signal quality, power etc.This closes pipeline equipment and also is built-in with power detection, standing wave detection module simultaneously, monitored signal is detected and with RS-485, or the protocol/port form of RS-232 externally connects, and can connect direct detection signal by local computing.Simultaneously equipment is also built-in radio modem is modulated the monitoring and detection signal, sends to the network monitoring center of appointment in the mode of wireless data sending, has saved lot of manpower and material resources.A plurality of mixer combinations have been adopted in inside, and have been used passive device combinations such as coupler, power splitter, isolator, electric bridge, make the system of closing the road substantially exceed the 2-3 road of common mixer, reach the 10-12 road.
Among the present invention, built-in miniature 6 port 30dB couplers in combiner unit input port are not taking on the basis of structural volume substantially, have increased by 1 tunnel system testing port, and another road coupling output offers built-in detection unit.
The built-in power detection unit detection unit of 3-G (Generation Three mobile communication system) TD-SCDMA time-division system (especially at) can carry out independent power detection to the signal of various inputs, standing wave detects.
The built-in miniature computer carries out digital-to-analogue conversion, coding, protocol processes to the analog signals of detection unit output and enables directly to give that locally-attached detection computations is machine-readable gets.
Built-in radio modem cooperates built-in microcomputer, the digital signal of computer output modulated, and by being wirelessly sent to the monitoring alarm center of far-end.
The invention has the beneficial effects as follows, can close the road in tens communication systems of multisystem such as interior mobile TV 600, TETRA800, CDMA800, GSM900, DCS1800, PHS1900, WLAN2500 at comprising 3G (Third Generation) Moblie WCDMA, TD-SCDMA, and provide simulation, numeral, monitor mode such as long-range, and device structure is firm, the insertion loss is low, good stability.
