Abstract

The utility model discloses a real -time on -line monitoring appearance of arrester based on nearly remote wireless transmission technique, it includes singlechip, clock circuit, lithium cell, leakage current mutual -inductor, signal pre -processing module, alarm unit, AD conversion module and temperature and humidity sensor, the input of singlechip passes through parallelly connected AD conversion module and alarm unit and signal pre -processing module to be connected with leakage current mutual -inductor electricity, and the output is connected with memory chip, GPRS communication module and zigbee emission module electricity. It uses to adopt zigbee short -range wireless communication technique and the long -range wireless data transmission technology of GPRS to mix to to the condition of difference, use different communication mode, not only its price is lower, can carry out real -time, accurate on -line monitoring to the arrester, can reduce the consumption of local moreover, prolongs the life of lithium cell, practices thrift communication cost, is favorable to popularizing and applying.

Description

A kind of spark gap real time on-line monitoring instrument based on nearly long range radio transmissions technology
Technical field
This utility model is related to a kind of spark gap real time on-line monitoring instrument, particularly a kind of to be based on Zigbee and two kinds of GPRS The spark gap real time on-line monitoring instrument of nearly long distance wireless data transmission technology.
Background technology
At present the monitoring device of domestic electric transmission line lightning arrester is broadly divided into two kinds:One kind is mechanical enumerator. This mechanical counter function is single, can only record the number of lightning strokes of spark gap, and because it is normally mounted at transmission of electricity At the position beside spark gap on shaft tower, thus it is higher apart from ground, cause fortune inspection personnel to be difficult to observe;Another kind is intelligent number Word formula monitoring instrument, although it with real-time monitoring and can store the number of lightning strokes of spark gap, response time and spark gap leakage electricity Stream situation and with functions such as data remote transmissions but not only expensive for it, and in running, power consumption compared with Greatly, the communication cost needed for data transmission is also higher, thus affects its popularization and popularization and application.
Utility model content
The purpose of this utility model is that offer is a kind of both can carry out live short distance using Zigbee wireless communication techniques Recruit data from short range, it is also possible to by GPRS long distance wireless data transmission technology and transfer data to backstage and price compared with The spark gap real time on-line monitoring instrument that low, power consumption is less, communication cost is relatively low.
Its technical scheme is:A kind of spark gap real time on-line monitoring instrument based on nearly long range radio transmissions technology, its feature It is:Turn including single-chip microcomputer, clock circuit, lithium battery, leakage current transformer, signal pre-processing module, alarm unit, A/D Mold changing block and Temperature Humidity Sensor;The input of single-chip microcomputer A/D modular converters in parallel and alarm unit and signal Pretreatment module is electrically connected with leakage current transformer, and outfan launches mould with storage chip, GPRS communication modules and Zigbee Block is electrically connected.
Its advantage is:This utility model adopts low-power consumption and without the need for the Zigbee wireless communication technologys of communication cost, The daily monitoring of single-chip microcomputer is gathered and stored in memory(The Monitoring Data of 1 year can be stored)Spark gap service data, lead to Cross the outside that Zigbee transmitter modules receive and recruit signal, data are read from storage chip, and launched by Zigbee Module to the Zigbee receiver modules of handheld device send, and patrol officer of being easy to transmit electricity is used in two kilometers of short ranges at the scene The handheld device of panel computer or subsidiary Zigbee receiver modules recruits at any time spark gap currently and historical data, is kept away by analysis The data such as the action frequency of thunder device, the change of leakage current, and corresponding humiture, accurately judge the defect inside spark gap And take appropriate measures, it is to avoid there is explosion accident in operating spark gap, be that the safe operation of equipment provides safeguard;Together When, using the GPRS wireless data transmission technologys of remote and signal stabilization, both can be will be stored in by GPRS communication modules Spark gap service data in memorizer, Long Distant Transmit to backstage host computer mitigates patrol officer and collects spark gap at a distance The hard work of service data, it is also possible to which real-time monitoring is carried out more than the spark gap of given threshold to Leakage Current by alarm unit; Once the leakage current of an arrester that leakage current transformer is collected triggers warning more than the threshold value of alarm unit setting, wake up The related datas such as thunderbolt, overvoltage are sent directly to host computer and use by single-chip microcomputer, single-chip microcomputer by GPRS communication modules immediately Family mobile phone, is reported to the police in time and is reminded.Therefore, passed using Zigbee short-range wireless communications technology and GPRS long distance wireless data Transferring technology is used in mixed way, and for different situations, using different communication modes, not only its price is relatively low, can be to lightning-arrest Device is carried out in real time, accurately monitor on-line, and can reduce the power consumption of the machine, extends the service life of lithium battery, saves logical Letter expense, is conducive to popularization and application.
Description of the drawings
Fig. 1 is this utility model electricity theory diagram.
Specific embodiment
As shown in figure 1, a kind of spark gap real time on-line monitoring instrument based on nearly long range radio transmissions technology, including monolithic Machine, clock circuit, lithium battery, leakage current transformer, signal pre-processing module, alarm unit, A/D modular converters and humiture Sensor;The input of single-chip microcomputer A/D modular converters in parallel and alarm unit and the signal for filtering, amplifying Pretreatment module is electrically connected with Leakage Current transformer, and outfan launches mould with storage chip, GPRS communication modules and Zigbee Block is electrically connected.Power supply needed for spark gap real time on-line monitoring instrument is supplied by lithium battery.
Above-mentioned spark gap real time on-line monitoring instrument under normal circumstances, Zigbee transmitter modules and GPRS communication modules with And single-chip microcomputer, all in Low-power-consumptiodormancy dormancy state, every 2 hours, single-chip microcomputer Jing A/D change-over circuits measured in real time letting out for spark gap Leakage current value, Temperature Humidity Sensor measures warm and humid degrees of data, and record storage related data, when Zigbee transmitter modules are received When outside recruits signal, then data are read from storage chip, by Zigbee from Zigbee transmitter modules to handheld device Receiver module sends, and at the scene two kilometers of interior panel computers of short range or subsidiary Zigbee connect to be easy to transmission of electricity patrol officer The handheld device for receiving module recruits at any time spark gap currently and historical data;Can also be will be stored in by GPRS communication modules Spark gap service data in memorizer, Long Distant Transmit to backstage host computer mitigates patrol officer and collects spark gap at a distance The hard work of service data;Situations such as there is thunderbolt, overvoltage, the spark gap leakage electricity that leakage current transformer is collected is caused Stream more than alarm unit setting threshold value when trigger warnings, wake-up single-chip microcomputer, number of times that single-chip microcomputer will be struck by lightning, spark gap are let out The real time data information such as the electric current of leakage and time, is actively sent to host computer and user mobile phone, in time by GPRS communication modules Reported to the police and reminded.
