The data server connects several RFID card readers simultaneously, realizes the voltage measurement on multiple testee surfaces, is counting According to the data base of the information of voltage on each testee surface of server construction, facilitate transient state between lateral comparison each testee Ground voltage (TEV) difference is determining the source of trouble.
The RFID card reader connects data server by wireless module, and the information of voltage long distance wireless on testee surface is passed Pass data server to be stored, it is not high to the status requirement of shelf depreciation harvester and RFID card reader, may be mounted at each Occasion is planted, the voltage measurement on partition domain testee surface is realized by wireless networking.
The processor unit is also connected with display unit, and display unit graphically shows the information of voltage on testee surface Show on monitored picture, intuitively reflect the information of voltage on testee surface.
The data server and processor unit are also connected with client, and user can check specific measured object by Terminal Server Client The real time data of the voltage signal of body.
Beneficial effect:Shelf depreciation intelligent wireless monitoring system of the present invention, reads shelf depreciation and adopts by RFID card reader The radiofrequency signal of storage, realizes real time on-line monitoring function, and the strong antijamming capability of radiofrequency signal, data sensitive degree is high;Will The voltage signal information real-time storage of testee is longitudinal by the long-term observation to a certain testee in data server Comparison reflects the long-term ageing process of the testee;By many in the measurement to multiple testees, particularly same system The source of trouble is found out in the measurement of individual test point, lateral comparison;When detecting that testee breaks down, warning is sent in time, and When fault message is notified into management personnel, process management personnel's very first time;Shelf depreciation harvester and RFID read in system Card device is easy for installation, it is adaptable to various environment, installs relatively simple.
