Below, the running of vehicle carried device in the past 1 shown in Figure 3 is described.
In Fig. 3, the 14 short of various interrupt signal inputs of control microcomputer just are in low consumption power mode (holding state), and in response to switch interrupts signal 16a, 17a, IC-card interrupt signal 18a or data interruption signal Da start into common pattern from the low consumption power mode.
Equally, transmitting element 13b in the RF unit 13 and protocol processing unit 15 turn back to the low consumption power mode after carrying out transmission reception processing.
At first, the user of vehicle carried device 1 is inserted into IC-card 3 in the control microcomputer 14, by means of generating IC-card interrupt signal 18a by IC-card sense switch 18, makes microcomputer 14 startings.
Then, the user is input to secret number in the control microcomputer 14 by figure key 19.At this moment, the secret number during with input is presented on the display unit 20, and is confirmed in real time by the user.
In addition, transmitting element 13b and the protocol processing unit 15 by initiating signal ER and EP starting also turns back to the low consumption power mode.
Then, when for example by user's operating operation switch 16 or 17,14 responses of control microcomputer are started from switch interrupts signal 16a, the 17a (showing request) of each console switch 16,17, and the IC-card data of reading in are presented on the display unit 20.
This occasion, control microcomputer 14 is responding to switch interrupt signal 16a, 17a also, generates initiating signal ER and EP, makes transmitting element 13b and protocol processing unit 15 startings in the RF unit 13, turns back to the low consumption power mode after Interrupt Process finishes.
On the other hand, receiving element 13a in the RF unit 13 is by the starting state that always is in common reception mode of operation from the power supply of power supply 21, approach the turn pike cash desk when one, just response receives the data from Lu Shangji 2, received signal is input to protocol processing unit 5, simultaneously data interruption signal Da is input to control microcomputer 14.
That is to say, go up the communication zone of machine 2, and reach setting when above, just generate data interruption signal Da from the electric field strength of the reception electric wave W1 of Lu Shangji 2 when receiving element 13a enters into to satisfy the need.Therefore, control microcomputer 14 can be discerned the communication zone that vehicle enters into the turn pike cash desk.
In addition, control microcomputer 14 response data interrupt signal Da, generate initiating signal ER and EP, make transmitting element 13b and protocol processing unit 15 startings in the RF unit 13, read in reception data RD by protocol processing unit 15, output among the transmitting element 13b by the transmission data TD of protocol processing unit 15 simultaneously necessity.
At this moment, the data-signal that the Lu Shangji 2 that is imported by reception antenna 11 by the receiving element 13a in the RF unit 13 is sent out is transformed into digital signal, and is input in the protocol processing unit 15.
In protocol processing unit 15, carried out retransmission process and data error detection by the received signal after the digital conversion and handle, become normal reception data RD, and be input in the control microcomputer 14 and handle.
Then, control microcomputer 14 will be input to the RF unit 13 from the transmission data TD that IC-card 3 is read by protocol processing unit 15.
Transmitting element 13b in the RF unit 13 is sent among the Lu Shangji 2 as sending radio wave W2 by transmitting antenna 12 after the transmission data TD that will be transfused to is transformed into analog signal.
Like this, when Interrupt Process one end of response data interrupt signal Da, transmitting element 13b and protocol processing unit 15 turn back to the low consumption power mode with control microcomputer 14.
Below, the operation to the control microcomputer 14 in the vehicle carried device in the past shown in Figure 31 describes with reference to the flow chart of Fig. 4.
Fig. 4 represents the processing operation of the control microcomputer 14 in the low consumption power mode.
In Fig. 4, control microcomputer 14 is on one side with the standbies of low consumption power mode, according to step S1～S3 constantly check and have or not interrupt signal on one side.
At first, judge whether import interrupt signal Da (step S1), if be judged to be not input (being "No"), whether then then judge input switch interrupt signal 16a or 17a (step S2), if be judged to be not input (being "No"), then then judge whether import IC-card interrupt signal 18a (step S3).
In step S3, do not import IC-card interrupt signal 18a (being "No") if be judged to be, then break away from the processing subprogram of Fig. 4 and return.
At this moment, control microcomputer 14 keeps low consumption power mode, inoperative transmitting element 13b and protocol processing unit 15.

Then, for and Lu Shangji 2 between communicate, control microcomputer 14A generates initiating signal ERA and EPA, makes transmitting element 13B and protocol processing unit 15A starting (step S12), carries out the communication process (step S13) of response data interrupt signal Da.
That is to say, control microcomputer 14A enters into the communication zone of regulation at vehicle carried device 1A, and receiving element 13a detects the occasion of the radio wave W1 of regulation electric field strength, response data interrupt signal Da also starts into normal operation mode, transmitting element 13B also starts into normal operation mode with protocol processing unit 15A, and the transmission data of necessity are sent among the Lu Shangji 2 as sending radio wave W2, and communicate mutually between the Lu Shangji 2.
Then, judge whether communication process finishes (step S14), if do not finish (being "No"), then fall back on step S13 and continue communication process, finish (being "Yes") if be judged to be communication process, then make transmitting element 13B and protocol processing unit 15A turn back to the low consumption power mode, and after self also getting back to low consumption power mode (step S6), process is returned.
On the other hand, the occasion in user's operating operation switch 16 or 17 in step S2, is judged to be input switch interrupt signal 16a and 17a (being "Yes"), and control microcomputer 14 starts into normal operation mode (step S21) from the low consumption power mode.
This occasion, because of needn't and Lu Shangji between communicate processing, so then control microcomputer 14A responding to switch interrupt signal 16a or 17a, only carry out the demonstration of IC-card data and handle (step S22), do not export initiating signal ERA and EPA.
For example, control microcomputer 14A will consume the big protocol processing unit 15A of electric power, and to maintain low consumption power mode state constant, IC-card 3 is switched on and read in IC-card data (valid expiration date and utilize resume), response from valid expiration date display switch interrupt signal 16a and show valid expiration date, response is from the interrupt signal 17a that utilizes the resume display switch and show and to utilize resume.
Then, judge whether the demonstration processing relevant with the IC-card data finishes (step S23), do not finish (being "No") if be judged to be, then fall back on step S22 and continue to show processing, finish (being "Yes") if be judged to be processing, after then getting back to low consumption power mode (step S6), process is returned.
That is to say, control microcomputer 14A the IC-card data read in end after, finish energising to IC-card 3, on display unit 20, show the IC-card data, after the demonstration of certain hour finishes, transfer to the low consumption power mode.
In addition, among the step S3, the user IC-card 3 is inserted into occasion among the vehicle carried device 1A, is judged to be input IC-card interrupt signal 18a (being "Yes"), control microcomputer 14A starts into normal operation mode (step S31) from the low consumption power mode.
This occasion, because of do not need yet with Lu Shangji 2 between communicate by letter, whether (step S32) handled in correct inspection when inserting so control microcomputer 14A only carries out IC-card 3, do not export initiating signal ERA and EPA.
That is to say, control microcomputer 14A is to answering IC-card interrupt signal 18a to start, with protocol processing unit 15A former state to maintain low consumption power mode state constant, IC-card 3 is switched on, with the intercommunication of IC-card 3, confirm consistency simultaneously with the secret number and the secret number in the IC-card 3 of figure key 19 inputs.
Then, inspection when judging the insertion of IC-card 3 handles whether finish (step S33), do not finish (being "No") if be judged to be, then fall back on step S32, and continuation IC-card data processing, finish (being "Yes") if be judged to be processing, then get back to low consumption power mode (step S6) after, process is returned.
That is to say that control microcomputer 14A finishes the energising to IC-card 3, and transfers to the low consumption power mode after confirming that IC-card 3 is whether in fact to vehicle carried device 1A effective I C card.
Like this, control microcomputer 14A only respond with Lu Shangji 2 between the data interruption signal Da that communicates by letter and need, make transmitting element 13B and protocol processing unit 15A (external equipment) starting, carry out and handle, and other interrupt signal to only can do with control microcomputer 14A, external equipment is maintained the low consumption power mode, carry out simultaneously and handle.
By said process, can reduce the consumption electric power of vehicle carried device 1A effectively.
Therefore, the battery in using vehicle carried device 1A can extending battery life as the occasion of power supply 21.In addition, reduce, can suppress the heating of vehicle carried device 1A owing to consume electric power.
Example 2
In the aforementioned example 1, when IC-card 3 inserts,, only with the mutually intercommunication of IC-card 3, whether correctly also can check with control microcomputer 14A without figure key 19 though, check whether IC-card 3 is correct from the secret number of figure key 19 inputs.
