Fig. 2 is the electrical block diagram of embodiment shown in Figure 1.
As shown in Figure 2, according to aforementioned, each input channel is one group with four, and each group is connected to a switch I C (switch I C1-5), and each switch I C is connected to CPU1 and the CPU2 in the control unit respectively.The operation of each unit in two CPU combined control systems of control unit.Two CPU all adopt AT90S8515, and they provide synchronizing clock signals by crystal-oscillator circuit X1 and X3 respectively, and wherein each capacitor C 1, C2, C4 and C5 all are chosen as 22pF.The PSEN of CPU1 and CPU2, ALE/PROG and EA/VPP (i.e. the 29th, 30 and 31 pin) connect respectively, carry out control operation so that cooperate.Under the control of control unit, various input data and RTC quantitative data input be to CPU1 and CPU2, simultaneously according to the A item number according to or the B item number according to and be stored in respectively among the EEPROM1 or EEPROM2 of memory cell.Real-time clock (RTC) unit is made of a crystal-oscillator circuit X2, provides RTC data-signal to control unit.Supervisory keyboard is connected to CPU2, and 5 button K1-K5 correspond respectively to different operations.LCD display is connected to CPU1 as an external equipment, when system according to the display button signal (LCD signal) of the supervisory keyboard by CPU1 when carrying out display subroutine, LCD display shows the storage data that will check in the mode of one or two English alphabet code name.As do not have new push button signalling, shown data can keep 10 minutes, returned main program then.CPU1 also comprises a printer interface, is used to connect chopping machine, when system according to the printing push button signalling (PRN signal) of the supervisory keyboard by CPU1 when carrying out print subroutine, chopping machine is just printed required storage data.As not having new push button signalling, print subroutine can be carried out 10 minutes, returned main program then.If import the PRN signal once more in print procedure, then chopping machine stops to print.
Fig. 3 a and 3b illustrate workflow diagram according to an embodiment of the invention shown in Figure 1.
Referring to Fig. 3 a, after power connection, at first carry out initialization and self-examination in step 301 system, can normal operation to guarantee system.Then, in step 302, internal clocking is set, and system picks up counting by 0.In step 303, CPU begins to read keyboard signal, and shows the RTC time at LCD display.In step 304, CPU has judged whether push button signalling.If there is not push button signalling, then judge that in step 305 whether internal clocking is through 1/3 second.If judge it is not then to return step 303.If judge through 1/3 second, then internal clocking put 0, and restart timing in step 306.
Then, in step 307, it is 0 that existing input channel is set, and reads the state of this passage in step 308.Shown in Fig. 3 b, judge in step 309 state this time read with on the state of this passage of once reading whether identical.If inequality, expression is occurred by new status data, then deposits this state and corresponding RTC time data in corresponding EEPROM (the A item number is according to depositing EEPROM1 in, and the B item number is according to depositing EEPROM2 in) in step 310.In step 311, adjust the pointers such as memory address of EEPRON, so that storage next time.Then, in step 312, judge whether existing input channel is last input channel.If not last input channel, then port number is added 1 in step 313, return step 303 then.
In addition, if judge in step 309 state this time read with on the state of this passage of once reading identical, then do not read this status data and direct execution in step 312.
If judge that in step 312 existing input channel is last input channel, then directly return step 303.
On the other hand, shown in Fig. 3 a, if judge have push button signalling to occur in step 304, then the instruction of push button signalling is carried out in procedure turn.At first, judge in step 314 whether push button signalling is the key signals of adjustment RTC (real-time clock).If judge to be, then carry out the subprogram of adjustment RTC in step 315.Then, judge in step 316 whether internal clocking reached 10 minutes.If not enough 10 minutes, then return step 315, continue to carry out the subprogram of adjustment RTC.If enough 10 minutes, then program was returned the step 303 of main program.
If judge it is not adjustment RTC key signals in step 314, program then judges in step 317 whether described push button signalling is LCD display key signal.If judge to be, then carry out the subprogram that is stored in the data among the EEPROM by the LCD display demonstration in step 318.The demonstration of being carried out is to be begun to show to echo one by one by up-to-date data once.(display key signal of every key entry just shows previous again data.) then, judge in step 319 whether internal clocking reached 10 minutes.If not enough 10 minutes, then return step 318, continue to show this time data presented.If enough 10 minutes, then program was returned the step 303 of main program.
If judge it is not LCD display key signal in step 317, program then judges in step 320 whether described push button signalling is PRN printing key signal.If judge to be, then in the subprogram of step 321 execution by printer prints canned data.The printing of being carried out is to be begun in terms by terms to returning seal by up-to-date data once.(when keying in a printing key signal again, printing just stops.) then, judge in step 322 whether internal clocking reached 10 minutes.If not enough 10 minutes, then return step 321, continue to print.If enough 10 minutes, then program was returned the step 303 of main program.
If judge it is not the printing key signal in step 320, then program is returned step 303.
As shown in Fig. 3 b, in the process of carrying out above-mentioned each subprogram, if the phenomenon of supply disconnecton takes place, then program is at step 323 interruption subroutine, then, and in step 324, because system detects supply disconnecton, just utilizes accessory feed that the corresponding RTC time is stored as power-off time.Then, in step 325, owing to power supply cuts off, so the system closure running.
Below with reference to accompanying drawing embodiments of the invention are illustrated.Can understand that those skilled in the art can carry out various modifications or change under the principle that does not break away from essence of the present invention and category, and these modifications or change all belong to the described scope of claims of the present invention.
