The difference of embodiment ten, this embodiment and embodiment one, two, four, six or nine described intelligent low-power consumption IC-card diaphragm gas meters is that alarm module 8 is a hummer.
The workflow of present embodiment is described in conjunction with Fig. 6:
1, system initialization
System initialization partly is provided with the input/output state and the high-low level of each pin of main control chip.In addition, because system is less demanding to real-time, therefore be provided with under the general mode, system clock source adopts chip internal DCO, and frequency is 1.048576MHz, so both can reduce power consumption, can make a response more quickly again.Adopt 32768HZ wrist-watch crystal oscillator and carry out 256 frequency divisions as LCD display driver frequency.
2, principal function
Behind the system initialization, program will detect supply voltage, when undertension, and valve-off, the protection system data, and point out under-voltage.System is in dormant state, waits for that the user changes battery.If the electric weight abundance, program will read tolerance information from EEPROM, if remaining sum is 0, then direct valve-off, and prompting is supplemented with money, opens IC-card and supplements interruption with money, enters dormant state subsequently, and after the user inserted IC-card and supplements with money, system just reworked.If also have remaining sum in the base table, whether program will detect remaining sum not enough, and (residue tolerance is less than 5M if Sorry, your ticket has not enough value 3), program is at the every 1M that uses of user 3Back prompting once and is opened IC-card and is supplemented interruption with money, but valve-off not allows the user to continue to use, and is 0 up to remaining sum.If the remaining sum abundance, then program directly detects flow, and handles.The MCU main control chip most of the time is in dormant state, wakes up by interruption and handles external event, so that the power consumption of system drops to is minimum.
3, interrupt routine
Because P1, the P2 port of MSP430 are polynary interruptions, so program detects interrupt source by detecting zone bit P1IFG, P2IFG.
A, flow detection are interrupted
The every use of user 0.001M 3, the gear of gear drive turns around, and the tongue tube adhesive once triggers a negative edge at the P1.1 mouth and interrupts, and after program detects, total use traffic is added 1 unit, and residual flow subtracts 1 unit.
B, IC-card insert and interrupt
After IC-card inserts, can produce negative edge at the P1.5 mouth and interrupt, can wake CPU up, make CPU withdraw from dormant state, the rebound master routine enters the IC-card handling procedure.
C, external damage detect interrupts
When the outside was attempted with ferromagnetic material destruction base table, the negative edge that the tongue tube that is used to detect can trigger the P1.3 port interrupted, and system's automatic-closing valve and protected data forbid using gas.
D, power-fail interrupt
When power supply power-fail, can produce a negative edge at the P2.0 mouth and interrupt, program can send current data to EEPROM, preventing loss of data, and valve-off, improve security.
4, IC-card is supplemented handling procedure with money
After inserting IC-card, whether program can detect the IC-card of insertion consistent with base table account name and password, thereby guaranteed table one card, and the Fei Benbiaoka insertion is invalid.If account password is correct, then the tolerance of supplementing with money in the IC-card can be deposited in the base table, and, finish and supplement handling procedure with money the IC-card zero clearing.
