Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Now, in conjunction with Figure of description, the utility model example is described in detail:
A kind of IC-card intelligent gas meter with GPRS transporting function, its theory diagram as shown in Figure 1, is comprised of microcontroller 1, inquiry button 2, LCDs 3, GPRS teletransmission control module 4, ESAM module 5, leakage alarm module 6, IC-card module 7, real-time clock module 8, metering module 9, power module 10, remote alarms module 11 and valve module 12; Microcontroller adopts TI MSP430F249 chip, by the existing inquiry button 2 of common I/O cause for gossip of microcontroller 1; LCDs 3 is communicated by letter with microcontroller 1 by spi bus interface; GPRS teletransmission control module 4 modes by asynchronous serial communication UART are communicated by letter with microcontroller 1; ESAM module 5 is communicated by letter with microcontroller 1 by the mode of iic bus; Leakage alarm module 6 is communicated by letter with microcontroller 1 by gas sensor control circuit; IC-card module 7 is communicated by letter with microcontroller 1 by reading and writing IC card circuit; Real-time clock module 8 is communicated by letter with microcontroller 1 by the mode of iic bus; Metering module 9 is communicated by letter with microcontroller 1 by gage probe control circuit; The all control of unidirectional reception microcontroller 1 of remote alarms module 11 and valve module 12; In addition, microcontroller 1 also comprises a hummer, an indication green light, an indication red light and an indication amber light.
Principle of work is as follows:
Intelligent gas meter installs, in battery case, load onto four joint alkaline batteries, LCDs 3 shows 000000, then in indicator gauge, remain tolerance, if tolerance is not 0, intelligent gas meter microcontroller 1 by-pass valve control module 12 is driven valve, to intelligent gas meter after sending " ticking " sound, enters normal operating condition, and user can start to use gas.
In user's use gas process, intelligent gas meter gathers electronic signal by metering module 9.When measurement unit 1 side of metering module 9, microcontroller 1 deducts fixedly measurement unit tolerance by the pulse signal of passing back.When the warning tolerance of stipulating lower than intelligent gas meter to residue tolerance in table with gas, intelligent gas meter microcontroller 1 is reported to the police by remote alarms module 11, LCDs 3 Chinese display " please be purchased gas " printed words, and report to the police once every regulation tolerance, reminding user is purchased gas in time.When intelligent gas meter use gas is to residue tolerance in table while being 0, intelligent gas meter microcontroller 1 by-pass valve control module 12 pass valves.If be provided with overdraw function in intelligent gas meter, plug-in card is opened valve continuation gas, and with when overdrawing tolerance value, intelligent gas meter microcontroller 1 by-pass valve control module 12 is closed valves, now plug-in card can not be driven valve, and overdraw tolerance will be removed by intelligent gas meter bales catch when user again purchases gas and enters to show.The tolerance that prestores in intelligent meter is finished closes after valve, user holds user's IC-card and purchases gas in corresponding site, by purchasing the IC-card module 7 of the user's IC-card insertion intelligent gas meter after gas, on IC-card, purchase tolerance value and write microcontroller 1, intelligent gas meter microcontroller 1 by-pass valve control module 12 is valve open, and user continues use gas.The price of intelligent gas meter writes in ESAM module 5, and microcontroller 1 upgrades intelligent gas meter operation price by real-time clock module 8, often walks side's gas, and microcontroller 1 carries out amount of money clearing according to unit price.In intelligent gas meter use gas process, if metering module 9 is encountered, magnetic is attacked or count signal transmission line broken string, and intelligent gas meter microcontroller 1 closes valve by protectiveness, and fault is got rid of rear plug-in card and driven valve.When if intelligent gas meter microcontroller 1 detects power module 10 cell voltages lower than certain electric weight, LCDs 3 can show " changing battery " printed words, and report to the police once every regulation tolerance remote alarms module 11, reminding user is changed battery in time, when battery electric quantity exhausts, intelligent gas meter microcontroller 1 by-pass valve control module 12 is closed valve, and after user replaces with new battery, plug-in card is opened the normal operation of valve intelligent gas meter recovery.When leakage alarm module has detected gas leakage, intelligent gas meter microcontroller 1 is reported to the police by long-distance alarm apparatus module 11.
Gas company can be by GPRS teletransmission control module 4 Real-time Obtaining intelligent gas meters gas consumption, purchase the information such as tolerance and residue tolerance, understand user's the vaporous condition of using; When gas intelligent gas meter, flow meter has abnormal information to occur, as battery is owed electricity, the situations such as tolerance deficiency, measuring apparatus mistake, gas leakage of purchasing are when occur, abnormal information reports background server in time, reminds gas company to note; Can readjust prices by 4 pairs of intelligent gas meters of GPRS teletransmission control module at any time in gas company, the pricing information of price modification writes ESAM module 5; Also can purchase after gas user, by 4 pairs of intelligent gas meters of GPRS teletransmission control module, carry out long-range supplementing with money; Also can pass through the switch of GPRS teletransmission control module 4 Long-distance Control intelligent gas meter valves.
