Description of drawings
System architecture according to communication network feeder monitoring system of the present invention shown in Figure 1 wherein shows in detail the annexation between all parts.
Embodiment
In accompanying drawing 1, show according to the communication network feeder monitoring system based on EPC GEN2 RFID technology of the present invention, the frequency hopping rfid interrogator (2) that adopts meets EPC GEN2 RFID technical specification, RFID label (1) meets the standard of EPC GEN2 RFID standard V1.2 version, wherein, rfid interrogator (2) is received on the incoming trunk (20) by dedicated coupler (3) and high performance filter (4) feedback, incoming trunk (20) is connected to power divider (10), and power divider (10) is connected to and is positioned at a plurality of RFID labels (1) that each communication network antenna (40) is located.
Frequency hopping rfid interrogator (2) is with frequency-hopping mode work, when monitoring, the frequency that frequency hopping rfid interrogator (2) selects to be different from the communication network operating frequency sends reads instruction, this is read instruction and is fed on the incoming trunk (20) by presenting the dedicated coupler (3) and the high performance filter (4) that connect with rfid interrogator (2), and then send on each RFID label (1) by power divider (10), read instruction in response to this, RFID label (1) is made and being replied, and answer signal is passed to frequency hopping rfid interrogator (2) along the path opposite with reading the command path.If the feeder line on the signal transmission passage is working properly, frequency hopping rfid interrogator (2) sends reads instruction and can be received by RFID label (1), replying equally that RFID label (1) is made can be received by frequency hopping rfid interrogator (2), form once effectively communication, frequency hopping rfid interrogator (2) can obtain the strength information of every RFID label inverse signal simultaneously.If the feeder line work on the signal transmission passage is undesired, frequency hopping rfid interrogator (2) sends reads instruction and can not received by RFID label (1), and inevitable can not the making of RFID label (1) replied.Perhaps, because antenna system coupling or antenna performance change, can directly cause the intensity of RFID label (1) inverse signal to change, frequency hopping rfid interrogator (2) is according to RFID(1) the situation of replying can analyze, determine to be connected to each antenna of communication network and the operating state of feeder line thereof.
In this system, frequency hopping rfid interrogator (2) emission radio-frequency queries signal, obtain the radiofrequency signal that RFID label (1) returns by dedicated coupler (3) and high performance filter (4) from feeder line, by inverse signal intensity being evaluated and tested the working condition of analogy portable antenna network.In this system, be provided with a RFID label (1) on each distribution antenna, and utilize original mobile communication antenna system that RFID label (1) is carried out intermittent operation, every certain interval of time carries out once RFID label (1), and adopts the operating state of analogue analysis method evaluation and test antenna system according to the intensity of inverse signal.
In the EPC of standard Class1 Gen2 technical specification, when rfid interrogator scanning RFID label, the RFID label can respond, the data code information of RFID label is turned back to rfid interrogator, and rfid interrogator can detect the intensity level that each RFID label returns radio signal simultaneously.For the RFID label that is installed in the portable antenna place, this inverse signal intensity level is decayed along with the increase of feeder line length, and antenna, feeder line, feeder line connector performance change, and also will cause the inverse signal decay.Physically after antenna and feed system installation, monitoring system is confirmed label and the inverse signal intensity of electronic tag on each antenna by automatic adjusting.In the scope that design covers, these inverse signal values are defined between the 0-65535.The purpose of adjusting is the active loss that eliminating feeder line length and various connector cause, and confirms the normal inverse signal intensity of each antenna.Read performance because EPC RFID has the group, within 3 seconds time, can scan and to identify 200 labels of as many as, namely in 3 seconds, both can finish and detect 200 mobile communication antennas of as many as.
The basis of realizing above-mentioned functions is rfid system and mobile communication indoor distributed system community antenna system.Rationally avoid the working frequency range of two systems, increase high performance filter apparatus and can finish the function of in non-interfering situation, passing through the scanning recognition analogy analysis antenna system working condition of RFID label.
Rfid interrogator (2) is strictly followed national radio control to the restriction of this type of equipment radio frequency power output, be coupled in the mobile communication antenna feeder system by dedicated coupler (3) and high performance filter (4), according to the certain hour interval RFID label that all are installed on the antenna is scanned, be shorter than in actual working time in time of 3 seconds and can evaluate and test 200 antennas of as many as.Owing to adopting the transient working mode, the band stray of rfid system signal is controlled in minimum degree to the degree of impact of mobile communication antenna feeder system when being subject to the strict restriction of high performance filter.
The instruction of reading that rfid interrogator (2) sends is delivered on each RFID label (1) by feeder line at one time, each RFID label (1) is replied receiving to make when reading instruction, answer signal returns rfid interrogator (2) simultaneously, so that the once monitoring of this monitoring system can be finished instantaneous, can not impact communication network.Simultaneously, because rfid interrogator (2) is frequency hopping, the frequency of reading instruction of transmission is different from the operating frequency of communication network, can not disturb mutually with the signal formation of communication network.
Rfid interrogator is built-in with power supply and power supervisor in (2), and the power supply of necessity is provided for the work of rfid interrogator (2), and power supply is managed.
Rfid interrogator also is provided with the interfaces such as LAN and/or 3G in (2), and simultaneously, rfid interrogator (2) is built-in with operating system, and operation upper layer application management system arranges with regard to the field program and state and upgrades by interfaces such as LAN and/or 3G.
By the explanation to the embodiment of the invention, can find that the present invention adopts relatively simple framework, no longer adopt high power amplifier, realized the fast monitored to communication network, avoided and former communication network in signal between disturb mutually.
Protection scope of the present invention is not limited to described specific embodiment, but is determined by the claims limited range.Those skilled in the art can be in the situation that do not break away from thought of the present invention the present invention improved and revises, these improvement and revise and must fall within the scope of protection of the present invention.
