The system comprises a near-end processing unit, a distribution network unit and a far-end processing unit; wherein, the near-end processing unit is composed of near-end signal processing subunits and a near-end power supply processing subunit; the far-end processing unit is composed of far-end signal processing subunits and a far-end power supply processing subunit; the near-end processing units send coded and modulated radio frequency signals to an antenna feeder system; after all the far-end signal processing subunits in the far-end signal processing unit receive the signals, codes are matched; after the codes are matched, the accurate far-end signal processing subunits return coded and modulated signals according to demands; the near-end signal processing subunits receive the signals returned by the far-end signal processing subunits; if the codes are matched accurately, the antenna feeder system is normal; conversely, the near-end signal processing subunits do not receive the demanded signals returned by the far-end signal processing subunits; and the signals are sent again for three times.
Description
Technical field
The present invention relates to mobile phone signal shielding field, particularly to a kind of antenna feeder detection system and method.
Background technology
At the prison, these Code in Hazardous Special Locations such as oil plant, gas station and examination hall, all do not allow to use mobile phone to carry out conversing or data transmission, and these places are built in by residential quarter mostly, not setting up cellular base station not all right again, this is accomplished by mobile phone signal is carried out selectivity interference shielding. Mobile phone signal interference shielding system contains 2G, 3G and the 4G network of CHINAUNICOM, China Telecom and China Mobile, and transmitting power is typically in about 10W. System configurations is usually transmitter unit and connects multiple antenna transmission system, it is common that 1 transmitter unit connects 16 antenna-feedback systems.
Owing to mobile phone signal has been carried out interference shielding so that lost contact to external world by the people of management and control, being difficult to accept in this information age, therefore they always want to destroy this equipment. Emission system is typically mounted at inside monitoring room, has special messenger to keep an eye on, and extraneous personnel are difficult to touch. And antenna transmission system is an exposure to aerial, it is very easy to wreck. Owing to being that an emission system connects multiple antenna transmission system, adopt traditional standing wave detection mode accurately not measure, more can not be accurately positioned. When one or several antenna transmission systems are destroyed, it is difficult to detection from emission system end and differentiates, can only check artificially.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, and a kind of antenna feeder detection system and method is provided, can automatically detect and position after antenna transmission system is destroyed, and report.
It is an object of the invention to be achieved through the following technical solutions. A kind of antenna feeder detection system, including: near-end processing unit, distribution NE, remote processor unit, wherein, near-end processing unit is processed subelement by near end signal and near-end power supply processes subelement and forms; Remote processor unit is processed subelement by remote signaling and far end supply processes subelement and forms; Wherein, near-end processing unit is arranged in main emission system, and remote processor unit is arranged on inside antenna transmission system;Near end signal processes subelement and remote signaling processes subelement and all has the device of radio-frequency receiving-transmitting function.
Wherein, because the working frequency range of main signal is 870MHz-2655MHz, described antenna feeder detection system adopts the operating frequency of radiofrequency signal to be 350-700MHz, and this is distant with main signal frequency phase-difference, adopt low-pass filtering method to make both can be good at isolation, will not produce to interfere; The voltage of near-end power subsystem and far end supply unit is filtered by high and low frequency electric capacity and the choke induction of high pressure voltage, obtains reliable and stable voltage and gives near end signal processing unit and remote signaling processing unit; Distribution network adopts the homophase synthesizer of WILLKISON principle, and distribution way can adopt 2-16 road.
A kind of antenna feeder detection method, near end signal processes subelement and sends the radiofrequency signal of encoded modulation in antenna transmission system, remote signaling in all remote signaling unit processes and carries out after subelement receives signal, to code, remote signaling correct after code being processed subelement and sending code modulated signal on request back to. Near end signal processes subelement and receives the signal that remote signaling process subelement is sent back to, and code is correct, then it represents that this antenna transmission system is normal. Otherwise near end signal processes subelement and does not receive the signal that required remote signaling process subelement is sent back to, then retransmit 3 times, if confiscating signal, then it represents that this remote signaling processes corresponding antenna transmission system and breaks down, and near-end processing unit shows this point failure and uploads.
The invention has the beneficial effects as follows: need not whether be destroyed by manual detection antenna transmission system, simple and reliable and cost-saved.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of antenna feeder detection system, this system includes: near-end processing unit 1, distribution NE 2, remote processor unit 3, and wherein, near-end processing unit 1 is processed subelement 101 by near end signal and near-end power supply processes subelement 102 and forms; Remote processor unit 3 is processed subelement 301 by remote signaling and far end supply processes subelement 302 and forms; Wherein, near-end processing unit 1 is arranged in main emission system, and remote processor unit 3 is arranged on inside antenna transmission system; Near end signal processes subelement 101 and remote signaling processes subelement 301 and all has the device of radio-frequency receiving-transmitting function.
Wherein, because the working frequency range of main signal is 870MHz-2655MHz, near end signal in described antenna feeder detection system processes subelement 101 and remote signaling processes subelement 301 and adopts radiofrequency signal operating frequency to be 350-700MHz, this is distant with main signal frequency phase-difference, adopt low-pass filtering method to make both can be good at isolation, will not produce to interfere; Near-end power supply processes the voltage of subelement 102 and far end supply process subelement 302 and is filtered by high and low frequency electric capacity and the choke induction of high pressure voltage, obtains reliable and stable voltage and gives near end signal process subelement 102 and remote signaling process subelement 302; Distribution NE 2 adopts the homophase synthesizer of WILLKISON principle, and distribution way can adopt 2-16 road.
