Embodiment FIG. 3 is a control block diagram showing an embodiment of the first invention.

Reference numeral 1 indicates a vending machine, and reference numeral 10 indicates a data collection device that collects sales data from the vending machine 1. In this data collection device 10, 11 is an interface for exchanging data with the vending machine 1, and 12 is an interface that exchanges data with the vending machine 1 via the interface 11.
This is a CPU (Central Processing Unit) that processes the sales data taken in from above and calculates the total power consumption by summing up the power consumption in each operating state and each power consumption. Reference numeral 13 is a ROM that stores power consumption per unit time (power consumption) during standby, operation, and communication as each operating state, and 14 stores time and sales data, etc. of each operating state. This is a RAM that stores . 15 is a rechargeable battery of this data collection device 10;
6 is an interface for communicating with the converter 20 for charging this data collection device 10;
is an indicator for displaying the remaining capacity of the battery 15. In the converter 20, 21 is an interface for communicating with the data collection device 10, and 22 is an interface for communicating with the data collection device 10.
This is a CPU that controls this converter 20. 24 is a rectifier circuit that obtains DC voltage from a commercial power supply; 25 is a charger that charges the battery 15 of the data collection device 10 with the DC voltage output from the rectification circuit 24; When combined, the charger 25 and the battery 15 are electrically connected.

The operation of the device having the above configuration will be explained below with reference to FIGS. 4 and 5.
The explanation will be given according to the flowchart. First, by loading the battery 15 into the data collection device 10, step S1
, this time is stored in the RAM 14 as the standby start time.
is memorized. In step S2, the CPU 12 determines the standby time H1 of the data collection device from the current time and the standby start time.
is calculated and stored in the RAM 14. When the power switch (not shown) of the data collection device 10 is turned on for data collection, the process proceeds from step S3 to step S4, where the CPU 12 calculates the total power consumption X [mAH] up to the present. The standby time, operation time (described later), and communication time (described later) of the data collection device 10 are H1, H2,
H3, and the respective current consumption amA, bmA,
cmA, each power consumption is aH1mA
H, bH2mAH, cH3mAH, and the total electric power Q[
mAH] becomes Q=aH1+bH2+cH3. In step S5, the remaining capacity of the battery is calculated. Here, if the capacity of the battery 15 is 500 mAH, the remaining capacity Y [%] is Y=(1-Q/500), and the value is displayed on the display 17. Note that immediately after the flowchart starts, the total power consumption Q is 0, so the remaining capacity is 100%. In step S6, the time when the power switch is turned on is stored as the operation start time. Thereafter, when sales data is communicated with the vending machine 1, the process advances from step S7 to step S8, and the time at this time is stored as the communication start time. After this, when the communication ends,
The process advances from step S9 to step S10, and the time from the communication start time to the end of communication is stored as communication time H3. When the power switch is turned off in step S11, the process proceeds from step S11 to step S12, and the time from the operation start time to the time the power switch is turned off is stored as an operation time H. Thereafter, by returning from step S13 to step S2, the remaining battery capacity Y is newly displayed in step S5. At this time, when, for example, 20% of the remaining capacity is displayed, it is necessary to charge the battery, so when this data collection device 10 is attached to the converter 20 for charging, the process proceeds from step S13 to step S14, where the CPU 12 calculates the Total power consumption Q
is transmitted to the CPU 22 of the converter 20.

On the other hand, in the converter 20, when the total power consumption amount Q is received, steps S51 to S52 are performed.
The charging time Ht is calculated using the following equation. Ht=
Total power consumption Q [mAH]/charging current [mA]·η, where η is a charging efficiency having a value less than 1. When the charging time Ht is calculated, step S54 and step S
55, the charging time is measured, and when the actual charging time reaches the calculated charging time Ht, charging is stopped, and
In step S53, a charging completion signal is sent from the charging converter 20 to the data collecting device 10, so that the data collecting device 10 proceeds from step S15 to step S16, and sets the standby time H1 and operating time stored in the RAM 14. H2 and communication time H3 are cleared and the process returns to step S1.

Next, the apparatus according to the second invention will be explained using the block diagram of FIG. 3 again. Here, the power consumption in each operating condition is stored in the ROM 23 on the converter 20 side, and only the time of each operating condition is sent from the data collection device 10 to the converter 20.
The PU 22 calculates the amount of power consumed for each operating condition, and the total power consumption is calculated by mutually adding these amounts of power consumption.The charging time corresponding to this total power consumption is calculated by the charger 25 The battery 15 is charged. According to the device of the second aspect of the present invention, since it does not have a ROM for storing power consumption and a calculation means for calculating the total power consumption, it can be formed with lower power consumption and smaller size, making it convenient to carry.

Next, a device according to a third aspect of the invention will be explained using the block diagram of FIG. In the figure, the same reference numerals as in FIG. 3 indicate the same members. In the figure, 30 is a RAM for storing data necessary for calculations, and 31 is a dip switch for mode switching. By switching this DIP switch 31, it is possible to set the mode to a fixed chargeable amount mode or a variable chargeable amount mode. The operation of the apparatus having the above configuration will be explained below according to the flowcharts of FIGS. 9 and 10. First, in step S20, the final standby time is memorized, and then in step S21, it is confirmed whether the customer has operated the power supply of the data collection device, that is, whether the power supply is ON, and
When it becomes N, the operation start time is stored in step S22. Next, in step S23, it is determined whether or not communication has started, and if it has started, the communication start time is stored in step S24. Next, in step S25, it is determined whether the communication has ended, and if it has ended, the communication time is calculated in step S26. Next, in step S27, it is determined whether the power is off, and if it is, the process proceeds to step S28, where a standby time is calculated. In step S29, the operating time is calculated and stored in the RAM 14. Next, power consumption is calculated by multiplying the standby time, operating time, and communication time by the standby power, operating power, and communication power, respectively, and outputs the power consumption from the interface 16 to the converter 20 and waits for charging. That is, in step S30, the total power consumption is transmitted to the converter 20, in step S61, the total power consumption is input, and in step S62, the total power consumption and the ROM2
The amount of charge is calculated from the amount of charge per unit time stored in step 3 and stored in the RAM 30. In the case of this invention, the DIP switch 31 is set to the fixed chargeability mode, so in step S63, the charge amount is compared with the chargeability amount stored in the ROM 23 and used to determine whether charging is possible. If the amount is exceeded, charging is started in step S64 and the process proceeds to step S65. In step S65, it is determined whether charging has ended, and if charging has ended, this charging end is communicated to data collection device 10, and charger 25 is turned off. The data collection device 10 waits for the end of charging in step S31, confirms and stores the standby start time in step S32, clears the operating time and communication time in step S33, and returns to step S20.

Next, the apparatus according to the fourth invention will be explained again using the block diagram of FIG. Here, the dip switch 31 is set to the variable charge availability mode. Based on the total charge amount that can be charged to a battery or the like and is stored in the ROM 23 and the past charge amount stored in the RAM 30, for example, the chargeable amount is determined by subtracting the maximum value of the past charge amount from the total charge amount, This charging capacity and RA
Compare the amount of charge stored in the M30, and if the amount of charge exceeds the chargeable amount, turn on the charger 25 and charge the battery 1.
Start charging 5.

[0020]

As explained above, the present invention calculates the power consumption of the data collection device for each operating condition and charges only the necessary amount based on the total power consumption. The battery is charged to the proper amount without too much or too little, eliminating problems such as not being able to collect data due to insufficient charging, or shortening the battery's lifespan due to overcharging. In addition, the appropriate amount of charge can be determined, allowing work to be carried out without waste, and it is possible to prevent damage to the battery and shortening of its lifespan due to repeated charging.
