Abstract
The utility model relates to the technical field of automation and in particular relates to a low-power wireless meter reading system. The low-power wireless meter reading system forms a five-layer transmission network comprising electricity meters, data collectors, a data concentrator, a GPRS (general packet radio service) wireless transmission module and a PC (personal computer) data center. The data of the plurality of electricity meters can be transmitted in real time through a 485 bus and a 485 multi-point parallel connection technology, so that the construction cost is greatly saved. The data collected by the plurality of data collectors are transmitted to the data concentrator through the 485 bus, processed and encoded by the data concentrator, wirelessly transmitted to the PC data center through the GPRS communication module, and processed, perfected and stored by a PC end. The problems of high meter reading workload, high error rate, low data statistic speed, poor real-time property and the like are solved and the power consumption of the system is greatly reduced.
Description
Technical field
The utility model relates to technical field of automation, relates to specifically a kind of low power consumption wireless meter reading system.
Background technology
Along with making constant progress and technology of Internet of things constantly perfect of society, in family or industry, energy use amount also increases rapidly thereupon, and traditional electric weight statistical model can not meet growing use amount statistics and modern management demand.
Concrete, traditional ammeter data acquisition scheme will rely on manually and read record before each user's watt-hour meter, staff's labor capacity is large, error rate is high, the statistics cycle is long, greatly hindered the development of smart power management system, and remote meter reading technology is arisen at the historic moment.
Summary of the invention
In view of the defect that prior art exists, the purpose of this utility model is to provide a kind of novel low power consumption wireless meter reading system, and this system is easy to use, and error rate is low, is particularly suitable for the user demands such as residential quarter watt-hour meter data acquisition, transmission, processing.
To achieve these goals, the technical solution of the utility model:
A system, comprising:
Some watt-hour meter;
Connect one to one respectively with described watt-hour meter, can Real-time Obtaining ammeter data and upload several data acquisition units of described data;
Be connected with described each data acquisition unit, can receive described data and by the data concentrator of uploading after data preparation coding;
Be connected with described data concentrator, the data wireless after data concentrator arrangement coding can be transferred to the GPRS wireless data transfer module of PC data center;
And decoding arranges the PC data center of filing after the data of GPRS wireless data transfer module transmission.
Further, described watt-hour meter is with RS-485 communication interface.
Further, single RS-485 bus is set on described data acquisition unit, for receiving the data from the transmission of watt-hour meter RS-485 communication interface.
Further, described data concentrator comprises relay module, for control data acquisition unit when not working in power-down mode.
Compared with prior art, the beneficial effects of the utility model: the utility model has formed by watt-hour meter, data acquisition unit, data concentrator, five layers of transmission network that GPRS wireless transport module HePC data center forms.A plurality of watt-hour meter get final product real-time Transmission by 485 multiple spot connection technology by single 485 buses, have greatly saved construction cost.The data of a plurality of data acquisition unit collections are sent to data concentrator by 485 buses, and concentrator is to being wirelessly transmitted to PC data center by GPRS communication module after its arrangement coding afterwards, and PC end can arrange perfect file to data.The problems such as effectively solved the workload of checking meter large, error rate is high, and the slow real-time of data statistics is poor, and greatly reduce the power consumption of system.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural framing figure of the utility model embodiment;
Fig. 3 is for controlling energy supply control module schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the technical solution of the utility model:
As shown in Figure 1, the utility model comprises some watt-hour meter;
Connect one to one respectively with described watt-hour meter, can Real-time Obtaining ammeter data and upload several data acquisition units of described data;
Be connected with described each data acquisition unit, can receive described data and by the data concentrator of uploading after data preparation coding;
Be connected with described data concentrator, the data wireless after data concentrator arrangement coding can be transferred to the GPRS wireless data transfer module of PC data center;
And file and analyze after the data of decoding arrangement GPRS wireless data transfer module transmission, and can to user, send corresponding arrearage according to data analysis, breakdown maintenance, the PC data center of energy-conservation prompting information service.
Above-mentioned watt-hour meter, data acquisition unit, data concentrator, GPRS wireless transport module HePC data center has formed five layers of transmission network of this kilowatt meter reading-out system.A plurality of watt-hour meter utilize the multiple spot of RS-485 connection technology to get final product real-time Transmission by single RS-485 bus, have greatly saved construction cost; After the data of a plurality of data acquisition unit collections are sent to data concentrator by RS-485 bus, data concentrator is wirelessly transmitted to PC data center by GPRS wireless data transfer module after it is arranged to coding, described PC data center is PC end, for data are arranged, improve to file and data basedly need to user, send arrearage by GPRS wireless transport module by what put in order, breakdown maintenance, the information services such as energy-conservation prompting.
Embodiment as shown in Figure 2 and Figure 3, concrete process is, between data acquisition unit and user's watt-hour meter, be to carry out data communication by the mode of 485 buses, and adopt DL/T645-2007 multifunctional electric energy meter communication protocol to realize the two-way communication between watt-hour meter and data acquisition unit.
When GPRS wireless transport module receives that power office requires the order of reading out data or the timer clock module of data concentrator to trigger alarm interrupt, the master controller of data concentrator is powered to each data acquisition unit by self I/O mouth pilot relay, reads watt-hour meter data after data acquisition unit reset initialization.Data acquisition unit will be sent to data concentrator by 485 buses after collecting data preparation coding again, and data concentrator will send by GPRS wireless transport module the PC data center that is positioned at power office to after the data preparation coding packing from each data acquisition unit again.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
