Description
Technical field
The utility model belongs to the power industry automation control area, is specifically related to the meter-copy collector of a kind of radio meter register or intelligence instrument.
Background technology
Flourish along with Chinese government utility, common people have higher requirement to living environment and quality thereof, so intelligent residence equipment arises at the historic moment.As the necessaries in the intelligent residence, intelligent meter data recording system has obtained flourish.Traditional manual meter reading method is because workload is big, efficient is low, can not monitor in real time etc. the electricity consumption situation, and the person of checking meter and some offending difficult situations of user can occur, causes the user not report, lie about, and then makes the statistics of data to carry out.
Along with carrying out of China's industrial system continuous development of the reform and electric network reconstruction engineering comprehensively, traditional manual meter reading method can not adapt to power department modernization and informationalized requirement.For satisfying the needs of electric network reconstruction, the wireless automatic meter recording system that cost is low, efficient is high, real-time becomes the first-selection of power department.At present, the intelligent construction of the electrical network of country is to replace traditional ammeter with the intelligent integral ammeter to cooperate wireless module to carry out automatic data logging, but make the electric network reconstruction cost very high to whole replacement of traditional ammeter, the electric network reconstruction construction difficulty of serious waste of resources, particularly vast rural area is big especially.Therefore need a kind ofly can simply transform the wireless kilowatt meter reading-out system that just can realize at traditional ammeter.
Summary of the invention
At above shortcomings in the prior art, the utility model at traditional ammeter of simple transformation provide a kind of can be fast, the stable concentrator of collecting ammeter data.
For realizing above-mentioned technical purpose radio meter register concentrator, the technical solution adopted in the utility model is as follows:
A kind of radio meter register concentrator, comprise radio frequency sending/receiving module, power module, MCU and GPRS module, described power module connects MCU and powers, described radio frequency sending/receiving module receiving radio data, radio frequency sending/receiving module connects described MCU, data after MCU handles send to the remote data terminal by the GPRS module, and described MCU is provided with the Flash reservoir of temporary transient storage data and the SD card of backup ammeter data.
Adopt the utility model of technique scheme, work in the following way: the photographing module on traditional ammeter is taken pictures to the ammeter counting, and this photo is compressed processing, sends by wireless module again.At this moment radio frequency sending/receiving module receives the data that ammeter sends, after through the data authentication ammeter image transmitted data are decompressed and image recognition, the relevant informations such as electric weight counting after will identifying again send to the remote data terminal by the GPRS module.The Flash reservoir can temporarily be stored data, and the SD card is preserved the data such as pictorial information that ammeter is sent automatically, makes things convenient for the remote data terminal to follow the tracks of user's data information like this, improves the stability of system with this.
Further, in order to guarantee the operate as normal of concentrator, described power module utilizes sun power and accumulator dual power supply, and the operating voltage that the voltage transitions chip is transformed into MCU is set, and has guaranteed the stability of intermodule inter-working.
Further, described MCU adopts based on the little process chip of the S3C2440 of ARM9 kernel.Because the S3C2440 chip has powerful operation capacity, abundant Peripheral Interface and integrated real-time clock function can satisfy concentrator to the requirement of energy consumption and arithmetic capability.In addition, along with the raising of image processing speed is very big, also further promoted the handling property of concentrator.
The utility model is identified the electric quantity data in the picture, and these data is sent to the remote data terminal by GPRS, thereby realize radio meter register by the ammeter counting picture of transforming the traditional ammeter transmission in back is handled.
Description of drawings
Fig. 1 is the structural representation of general wireless kilowatt meter reading-out system;
Fig. 2 is the structural representation of the utility model radio meter register concentrator.
Embodiment
In order to make those skilled in the art understand the utility model better, below in conjunction with drawings and Examples technical solutions of the utility model are further specified.
Figure 1 shows that the structural representation of general wireless kilowatt meter reading-out system, comprise data acquisition unit, data concentrator and data terminal, when data terminal needs ammeter data, then send instruction to each data concentrator, data concentrator then sends the data upload instruction to data acquisition unit, data acquisition unit receives the instruction back and gathers ammeter information, issue data concentrator in the lump together with information such as Customs Assigned Numbers, data concentrator is verified the information that receives and is handled, information after at last all being handled sends to data terminal, realizes wireless kilowatt meter reading-out system.Because wireless kilowatt meter reading-out system is according to its range of application, the consideration of different problems such as location circumstances and data security, concrete communication protocol, system hardware etc. all can be different.
Fig. 2 is the structural representation of radio meter register concentrator, comprise radio frequency sending/receiving module, power module, MCU and GPRS module, described power module connects MCU and powers, described radio frequency sending/receiving module receiving radio data, radio frequency sending/receiving module connects described MCU, data after MCU handles send to the remote data terminal by the GPRS module, and described MCU is provided with the Flash reservoir and is used for temporary transient storage data, also is provided with the SD card and is used for backing up the data that receive.For guaranteeing the operate as normal of concentrator, power module utilizes sun power and accumulator dual power supply, the mission life of raising equipment, the built-in voltage conversion chip can be transformed into supply voltage the operating voltage of the needs of MCU simultaneously, has guaranteed the stability of intermodule inter-working.MCU adopts based on the little process chip of the S3C2440 of ARM9 kernel, because the little process chip dominant frequency of S3C2440 is that 400 MHz(reach as high as 533MHz), aboundresources on the sheet has powerful operation capacity, abundant Peripheral Interface and integrated real-time clock function can satisfy concentrator to the requirement of energy consumption and arithmetic capability.
Described radio frequency sending/receiving module adopts the Zigbee wireless communication technology, present embodiment selects for use the DRF1605 module to be connected with the MCU serial ports, need not consider agreement during transmission, directly adopt the data penetration transmission technology, all modules power on and get final product automatic network-building in addition, can the fine condition that satisfies in the wireless kilowatt meter reading-out system.
After described power module adopts dual power supply, just can utilize daytime solar powered and charge a battery, evening storage battery power supply, this power module supply voltage is 5V, earlier through voltage stabilizing diode and fuse, by voltage transitions chip SPX1587 voltage transitions is become behind the 3.3V to the MCU power supply, diode, fuse have guaranteed stability and the security of power module.
