Further, described Temperature sampler, antenna and SAW temperature sensor are contained in a switch cubicle.
Further, described SAW temperature sensor (2) adopts surface acoustic wave techniques to complete SAW temperature sensor (2) temperature information transmission around.
Further, described Temperature sampler converts the alternating current in electrical network to 12V direct current that Temperature sampler needs.
Further, described SAW temperature sensor (2) is passive sensor, the electromagnetic wave signal that its energy source sends in Temperature sampler (1).
Further, the connection between the responsible Temperature sampler (1) of described bus (5) and communication processor (6) and the connection between communication processor (6) and monitoring management machine (7).
Further, described monitoring management machine (7) also has the function that shows, describes current demand signal state, protocol conversion and warning.
The utility model provides a kind of wireless and passive power equipment temp measuring system based on surface acoustic wave techniques.Wherein SAW temperature sensor self does not need power supply, relies on external electrical network that energy is provided by Temperature sampler, and the life-span of system is very long like this; Based on surface acoustic wave techniques, this switch cubicle can be worked under rugged surroundings; The collection period of Temperature sampler is very fast, can reach 100ms, makes sweep frequency very fast.
Brief description of the drawings
Fig. 1 is the overall construction drawing of system described in the utility model.
In figure, 1 is Temperature sampler, and 2 is temperature sensor, and 3 is antenna, and 4 is switch cubicle, and 5 is bus, and 6 is communication processor, and 7 is monitoring management machine, and 8 is system communication interface.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment: a kind of wireless and passive power equipment temp measuring system based on surface acoustic wave techniques, elaborates to method provided by the invention in conjunction with Fig. 1.
Concrete, 1 li of Temperature sampler has power conversion chip, and its effect is to convert the alternating current in electrical network to 12V direct current that Temperature sampler 1 needs.The electromagnetic wave signal that SAW temperature sensor 2 sends by Temperature sampler 1 obtains energy, therefore SAW temperature sensor 2 is passive.
First monitoring management machine 7 sets temperature acquisition cycle T and sends it to Temperature sampler 1 according to concrete environment, and collection period T herein can reach 100ms the soonest, therefore makes Temperature sampler 1 sweep frequency fast especially.The temperature acquisition cycle T of receiving is sent to SAW temperature sensor 2 by Temperature sampler 1.SAW temperature sensor 2 utilizes surface acoustic wave techniques that SAW temperature sensor 2 temperature information is around sent in Temperature sampler 1.Temperature sampler 1 is sent to communication processor 6 by bus by temperature information, then is transferred in monitoring management machine 7 via bus 5.Monitoring management machine 7 is connected with a central master station of system outside by system communication interface 8RS-232, can realize the real time on-line monitoring to temperature.Monitoring management machine 7 all can cause warning in 2 kinds of situations below occurring: (1), exceed the temperature value of setting; (2), in official hour, do not receive temperature signal.
Wherein, because SAW temperature sensor 2 is owing to adopting surface acoustic wave techniques, volume is very little, and synthermal collector 1, antenna 3 are arranged in a switch cubicle 4 together.
Communication processor 6 is main to be responsible for distributing and management Temperature sampler 1, the information that communication processor 6 gathers Temperature sampler 1 is passed to monitoring management machine 7, wherein Temperature sampler 1 adopts custom protocol to communicate, monitoring management machine 7 communicates by ICE103/104 or the ICE61850 agreement of state's network mark standard, and two kinds of agreements are directly changed in monitoring management machine 7.The temperature information that Temperature sampler 1 obtains parsing by RS485 bus 5 is passed to monitoring management machine 7.Monitoring management machine 7 can be with the processor of Presentation Function or computer, and the temperature information that communication processor 7 is sent is shown on display screen; Monitoring management machine 7 also has the protocol conversion function of self-defining Temperature sampler 1 protocol conversion Cheng Keyu monitoring management machine 7 direct communications itself.
