Abstract
The utility model relates to an overhead line fault indicator, comprising a central processor CPU, wherein an A/D conversion module used for acquiring current signals of the overhead line and a radio frequency chip connected with a radio frequency antenna are integrated in the central processor CPU, and the central processor CPU is communicated with a master station via the radio frequency antenna. On one hand, the A/D conversion module acquires and monitors current signals of the overhead line and captures fault signals by determining time change rate of the current signals, and on the other hand, the high performance industrial grade radio frequency chip is integrated in the central processor CPU and can be connected with the radio frequency antenna, and the radio frequency chip can be wirelessly communicated with the master station via the radio frequency antenna and can report real-time data and fault index information. Because the radio frequency chip is a self-bring chip of the central processor CPU, so integrated level is high, outward enlarging is not needed, hardware structure is simple, and cost is low.
Description
Technical field
The utility model relates to the indicator field, especially a kind of pole line fault detector.
Background technology
Traditional pole line fault detector has two kinds of indicating fault modes, and a kind of is that drive motor rotates indication fault, and another kind is to utilize alarm lamp to show fault.It is thus clear that, traditional pole line fault detector not with the main website communication, report the function of failure message and real-time Monitoring Data.A spot of fault detector that has with the main website communication function is arranged on the market, and its radio-frequency module needs outside expansion, and complicacy formed by hardware and cost is high.
The utility model content
The purpose of the utility model is to provide that a kind of cost is low, circuit structure simple, can and report the pole line fault detector of failure message with the main website communication.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of pole line fault detector; Comprise central processor CPU; The inner integrated radio frequency chip that is used to gather the A/D modular converter of current signal on the pole line and is used for being connected with radio-frequency antenna of central processor CPU, central processor CPU is through radio-frequency antenna and main website communication.
Can know that by technique scheme on the one hand, the utility model is gathered monitoring through the inner A/D modular converter of central processor CPU to current signal on the pole line, judges that the time rate of change of current signal is caught fault-signal; On the other hand, the inner integrated high performance technical grade radio frequency chip of central processor CPU can be connected with radio-frequency antenna; Wireless communication mode and main website communication through radio-frequency antenna; Reporting real-time data and fault indices information, because this radio frequency chip is that central processor CPU carries chip, integrated level is high; Need not to extend out, hardware configuration is simple and cost is low.
Description of drawings
Fig. 1 is the circuit block diagram of the utility model.
Embodiment
A kind of pole line fault detector; Comprise central processor CPU; The inner integrated A/D modular converter 1 that is used to gather current signal on the pole line of central processor CPU, be used for the radio frequency chip 2 that is connected with radio-frequency antenna 4, central processor CPU is through radio-frequency antenna 4 and main website communication, and is as shown in Figure 1.
As shown in Figure 1; Described central processor CPU adopts CC430F6137 chip 3; CC430F6137 chip 3 inner integrated A/D modular converters 1 and radio frequency chip 2; Three-phase current signal on the pole line links to each other with amplifier input terminal, and the output terminal of amplifier links to each other with the signal input part of A/D modular converter 1, and current sampling signal is connected with the inside A/D modular converter of its CPU after the amplifier processing and amplifying.
Described radio frequency chip 2 is the CC1101 chip, and the RF interface of CC1101 chip inserts radio-frequency antenna 4, and radio-frequency antenna 4 is through concentrator and main website communication.Described CC430F6137 chip 3 passes through I
2The C bus links to each other with storer 5, but storer 5 record circuit service datas and line fault information, the information inquiry during convenient line maintenance in the future.The liquid crystal drive pin of CC430F6137 chip 3 links to each other with LCD LCDs 6, makes things convenient for the demonstration of essential information, and described LCD LCDs 6 is the segmentation LCDs, and power circuit is to 3 power supplies of CC430F6137 chip.
It is thus clear that described CC430F6137 chip 3 is inner integrated high performance technical grade radio frequency chip 2---CC1101 chip can connect radio-frequency antenna 4 through its RF interface, wireless communication mode and main website communication through radio-frequency antenna 4 report failure message.Simultaneously CC430F6137 chip 3 has 8 12 A/D sampling channels, maximum 96 sections liquid crystal drive---LCD LCDs 6, two timers, an asynchronous serial port, a SPI/I
2C mixing serial ports, the product integrated level is high, and cost is low.
As shown in Figure 1, the I/O interface of described CC430F6137 chip 3 links to each other with drive motor, light sensor and alarm lamp respectively.The utlity model has the alarm indication function, when fault took place, CC430F6137 chip 3 drove drive motor and rotates, and drive motor drives the round turntable that is installed in the indicator bottom and rotates, and plays the effect that caution is reported to the police.If weather visibility lower or evening; The photosensitive circuit signal of indicator can't conducting CC430F6137 chip 3; Then 3 drive installations of CC430F6137 chip are lighted at the inner alarm lamp of round turntable, can effectively increase the visibility of alerting signal, make things convenient for the maintainer to find faulty line.
CC430F6137 chip 3 in the utility model is gathered current signal through its inner integrated A/D modular converter 1, judges that the time rate of change of current signal is caught fault-signal, and CC430F6137 chip 3 is gone into storer 5 with this event of failure content record; Wireless communication mode and concentrator communication through radio-frequency antenna 4; Report fault through concentrator to main website, drive motor rotates simultaneously, shows faulty line; And, light alarm lamp according to the brightness of photosensor signal judgement weather.
