According to the invention, the problems that the wake-up time of the wireless meter reader is long and the accounts can not be treated in-situ are solved.
Description
Technical field
The present invention relates to a kind of rapid meter reading on-site printing system.
Background technology
The data of current all kinds of water, electricity, gas tables are copied and accepted, are provided with, and the field adjustable of on-site data gathering such as environmental protection, chemical industry and various kinds of equipment is measured and all will be used acquisition terminal and meter-copy device.
And the transmission mode of the wireless meter reading that present domestic kilowatt meter reading-out system is used is mostly based on the infrared transmission of light emitting diode.There are several shortcomings in such system: 1, can introduce the light disturbing effect; 2, communication reliability is poor; 3, communication distance is near.Yet when getting at copying of a certain specific user, its mass-sending wake operation time just seems longer, remains to be shortened wakeup time, process speeds operations.In addition, the printing of bill is printed mailing, long processing period after need returning corporate HQ's processing again.
Summary of the invention
Technical matters to be solved by this invention is: at problems of the prior art, propose a kind of rapid meter reading and on-the-spot print system in time.
The present invention is achieved in that
A kind of rapid meter reading on-site printing system, the wireless radiofrequency meter-copy device that comprises control center, links to each other with the wireless transmission acquisition terminal by wireless signal, the table tool that contains gage probe, described wireless radiofrequency meter-copy device comprises wireless radiofrequency module, storer and the thermal printing movement that links to each other with main control chip.
Be provided with the operation valve that links to each other with described wireless transmission acquisition terminal in the described table tool.

Embodiment
Referring to accompanying drawing 1, a kind of wireless quick collection print system of the present invention mainly is made up of wireless radiofrequency meter-copy device, wireless transmission acquisition terminal and computer controlling center.
Accompanying drawing 2 as seen, wireless transmission acquisition module SR-8007 links to each other with the table tool, the pulse signal that direct collection water meter, gas meter, flow meter send also carries out automatic gauge, and the AVR single-chip microcomputer is monitored constantly by interrupt mode and prevented taking out stitches, prevents that trimming and remote installed meter tool are subjected to the signal of rogue attacks simultaneously.Whether the single-chip microcomputer electric weight that also will monitor power supply simultaneously can keep system works in addition, if battery electric quantity is lower than the minimum amount of power of default, single-chip microcomputer will produce warning and by wireless radiofrequency communication chip CC1100 and wireless communication signals treatment circuit UPG2214TK, alerting signal be launched.Wireless radiofrequency communication chip and wireless communication signals treatment circuit mainly be that the various data of system and parameter are carried out wireless transmission, the wireless radiofrequency information that has gone out to amplify from antenna transmission.According to the instruction that receives, the AVR single-chip microcomputer is by the open and close of interface control table tool inner control valve.
Referring to accompanying drawing 3, the wireless radiofrequency meter-copy device comprises the serial ports that links to each other with computer controlling center by USB communication cable or RS-232, on-the-spot mini-printer and the wireless radiofrequency module of printing bill at once.
Among Fig. 4, the CPU main control chip of wireless radiofrequency meter-copy device adopts the S743A compact of 32 high-speed CPUs of ARM (Advanced RISCMachines) of U.S. ST company product, high-performance flash memory microprocessor is as main control chip, the static RAM SRAM of the 39VF800A type flash memory (Flash Memory) of the American SS T company of Xiang Lianing and the CS18LV10243ECR70 of U.S. CHIPLUS company therewith, two 4 tunnels analogy switch 74HC4052D of Philip company and 42 inputs or door HC32D form touch screen control circuit, and composition such as the CH372 type USB common apparatus interface chip main body of checking meter; The LTP1245 type thermal printing movement of a built-in NSK (SEIKO) company, by battery-operated, print speed is 62.5mm/ second, paper is wide: 57.5mm.
The wireless radiofrequency module, SR-1106 type wireless communication module for Shanghai Sunray Technology Co., Ltd., the wireless transmission acquisition terminal is that the SRWF-8007 of Shanghai Sunray Technology Co., Ltd. wakes the bright digital transmission module of full impregnated fast up, and these two modules are the commercially available prod.When meter-copy device at the scene during the user's of copy reading community table tool content, the CPU main control chip sends the wireless radiofrequency instruction through wireless radiofrequency module SR-1106, wakes this user's wireless transmission acquisition terminal real-time up; The wireless transmission acquisition terminal IMU that is waken up is crossed Wireless transmission mode, and the continuous data and the table tool parameter of relevant table tool returned to meter-copy device, and all functions were all finished between 1.6 seconds.In case of necessity, can send operation valve in the steering order shutoff table tool by the wireless transmission acquisition terminal.After data acquisition finishes, print the bill form by thermal printer and pay the user, last meter-copy device will be destroyed the data importing calculation control center of getting through USB common apparatus interface again.
