[2] Operation of Embodiment [2.1] Operation of Wireless Communication Device of Vending Machine Next, an operation example of the wireless communication device 17 of the vending machine 10 will be described with reference to FIG. First, as shown in FIG. 6, the CPU 11 of the vending machine 10
It is determined whether or not the current time measured in the above belongs to any of the time zones in which wireless communication is possible (step S1). If it is determined in step S1 that the current time belongs to any of the time zones where wireless communication is possible (step S1; YES), the CPU 11 turns on the power of the wireless communication device 17. (Step S2).
Then, the process proceeds to step S1. in this way,
Only when the power of the wireless communication device 17 is ON, the wireless communication device 17 can communicate with the management server 30.

On the other hand, if it is determined in step S1 that the current time does not belong to any of the time zones in which wireless communication is possible (step S1; NO), the CPU
11 turns off the power of the wireless communication device 17 (step S3). Then, the process proceeds to step S1.
The above is the operation performed in one vending machine.
In the present embodiment, a similar operation is performed by a plurality of vending machines. Here, focusing on the three vending machines 10a, 10b, and 10c having the same telephone number, the operations performed by them are as follows.

First, as shown in FIG. 7, time t is 0: 0.
When it becomes 0, the CPU 11 of the wireless communication terminal installed in the vending machine 10a turns on the power of the wireless communication device 17 and shifts to a state where communication is possible. This is because time 0:00 belongs to a time zone in which the wireless communication terminal of the vending machine 10a can communicate. On the other hand, vending machines 10b and 10c
Each wireless communication terminal turns off the power supply to each wireless communication device 17 and keeps the state where communication is impossible.

Next, when the time t shown in FIG. 7 becomes 0:55, the CP of the wireless communication terminal installed in the vending machine 10a is set.
U11 turns off the power of the wireless communication device 17 and shifts to a state where communication is impossible. This is because time 0:55 does not belong to the time zone in which the wireless communication terminal of the vending machine 10a can communicate. Further, the wireless communication terminals of the vending machines 10b and 10c continue to be in a state where communication is impossible.

Next, when the time t becomes 1:00, the CPU 11 of the wireless communication terminal installed in the vending machine 10b,
The power of the wireless communication device 17 is turned on to shift to a state where communication is possible. This is because the time 1:00 belongs to a time zone in which the wireless communication terminal of the vending machine 10b can communicate. On the other hand, the wireless communication terminals of the vending machines 10a and 10c continue to be in a state where communication is impossible. Next, when the time t becomes 1:55, the CPU 11 of the wireless communication terminal installed in the vending machine 10b turns off the power of the wireless communication device 17.
Set to FF to shift to a state where communication is not possible. Time 1:
55 is because the wireless communication terminal of the vending machine 10b does not belong to the communication time zone. The vending machine 10a
Each wireless communication terminal of 10c and 10c continues the state where communication is impossible. Hereinafter, the same applies.

In the present embodiment, as illustrated in FIG.
Each time zone TL (Time-L) from 0:55 to 1:00, 1:55 to 2:00, 2:55 to 3:00
In ag), the wireless communication terminals of all vending machines cannot communicate. If the TL is provided in this manner, if the TL is not provided, when the current time indicated by the clock unit 18 of each wireless communication terminal is shifted, a plurality of wireless communication terminal devices can communicate simultaneously due to the difference. This is because there is a possibility that the state may become abnormal. Each clock unit according to the present embodiment is provided with a radio clock, so that the time measured by each clock unit can be substantially set to the standard time. Therefore, it is possible to further reduce the setting of the TL. Therefore, it is possible to set more time zones in which the wireless communication terminal of each vending machine can communicate.

[2.2] Operation of the Entire System There are two methods for collecting information such as the sales amount of the product from each vending machine. The first method is a method in which a wireless communication terminal installed in each vending machine makes a call to the management server and transfers information such as the sales quantity of the product to the management server. The second method is a method in which the management server calls a wireless communication terminal installed in each vending machine and collects information such as the sales amount of the product from each wireless communication terminal. Hereinafter, an operation example of the present embodiment will be described assuming each of these methods.

[2.2.1] Operation example in which the wireless communication terminal of each vending machine transmits to the management server In this operation example, the CPU 11 of the wireless communication terminal installed in each vending machine is shown in FIG. Execute the flow.
First, the CPU 11 determines whether or not the current time measured by the clock unit 18 belongs to any of the time zones in which wireless communication is possible (step S11). Step S
If it is determined in step 1 that the current time does not belong to any of the time zones where wireless communication is possible (step S11; NO), the CPU 11 repeats step S11.

On the other hand, if it is determined in step S11 that the current time belongs to any of the time zones where wireless communication is possible (step S11; YES), C
The PU 11 determines whether or not data transfer to the management server has already been performed in the time zone (Step S1).
2). If the result of this determination is "YES", the process returns to step S11. On the other hand, if the determination result is “NO”, the CPU 11 turns off the power of the wireless communication device 17.
At the same time as N, transmission processing to the management server is performed by the wireless communication device 17 to communicate with the management server 30 (step S13). Here, when the management server is busy and cannot be connected, the wireless communication device 17 calls again after a predetermined time has elapsed. This call is repeated again and again in a time zone in which communication is possible, until connection to the management server 30 is made.

When a call is connected to the management server 30 and communication becomes possible, the CPU 11 transfers various data stored in the EPROM 14 to the management server 30 by the wireless communication device 17 (step S14). ). Here, the various data include, for example, data on the number of remaining commodities in the vending machine 10a, data on the number of commodities sold, change data, and failure data. After transmitting various data to the management server 30, the CPU 11 causes the wireless communication device 17 to execute a process of disconnecting the call connected to the management server 30 and supply the power supply voltage to the wireless communication device 17. Is cut off (step S15). Then, the process returns to step S11. Thereafter, the process proceeds to step S11
Then, the process proceeds to step S12. At this time, since the data transfer to the management server has already been performed, the determination result in step S12 is "YES". For this reason, the power supply of the wireless communication terminal 17 is kept OFF until the communication available time zone ends and the next communication available time zone starts.
11 and S12 will be repeated. The same operation is performed in a wireless communication terminal installed in another vending machine.

[2.2.2] Operation of calling a wireless communication terminal from the management server to collect information In this operation example, the CPU 31 of the management server 30
Every time the current time is updated, the schedule storage area 35
With reference to all the telephone number-specific TS tables 35T, it is determined whether there is a wireless communication terminal that can communicate at the current time. If there is a wireless communication terminal that can communicate at the current time, whether information such as the sales volume of the vending machine has been collected from the wireless communication terminal (what should be collected in a communicable time zone to which the current time belongs) Determine whether or not. If the collection has not been completed, the wireless communication terminal is called using the telephone number specified in the telephone number-specific TS table 35T.

The wireless communication terminal installed in the vending machine 10 turns on the power of the wireless communication device 17 only in a time zone determined to be communicable by the vending machine-specific TS table 15T. Here, the time zone determined to be communicable does not overlap between a plurality of wireless communication terminals having the same telephone number. Therefore, even if a call is made from the management server 30 using a common telephone number for a plurality of wireless communication terminals, only one wireless communication terminal responds to a call using one telephone number. is there. The management server 30 that has called the wireless communication terminal collects information such as the sales volume of the vending machine 10 in which the wireless communication terminal is installed from the wireless communication terminal. The management server 30 that has collected this information uses the time of collection and the telephone number of the wireless communication terminal of the collection destination as clues, and uses the telephone number-specific TS table 35T to automatically set the wireless communication terminal of the collection destination. The vending machine 10 can be specified.

[2.3] Downloading of Various Information from Management Server to Wireless Communication Terminal of Vending Machine Next, referring to FIG. 9, the management server 30 sends a call to the wireless communication terminal of the vending machine. Vending machines 10a, 10b,
An operation example when downloading various programs and data to the wireless communication terminal 10c will be described. First, as shown in FIG. 9, the CPU 31 of the management server 30
Performs transmission processing to the wireless communication terminal to communicate with the wireless communication terminal of the vending machine 10 (step S2).
1). More specifically, the CPU 31 performs a calling process using, for example, the telephone number “090-999-1111” stored in the telephone number-specific TS table 35T shown in FIG. And in the example shown in FIG.
The communication control unit 37 sets the telephone number “090-9999-111”
Assuming that a call is made at 0:05 using "1", the communication control unit 37 establishes a call connection with the wireless communication terminal of the vending machine 10a which is ready for communication at 0:05. Become.

When a call is connected to the wireless communication terminal of one vending machine 10 and communication becomes possible, the management server 30
CPU 31 downloads various programs and data stored in HDD 34 to the wireless communication terminal of vending machine 10 (step S22). Here, various programs include programs for controlling remaining number management, sales number management, change management, failure management, and the like executed in the vending machine. Various data include, for example, vending machine T used by each wireless communication terminal
There is an S table. After downloading various programs and data to the wireless communication terminal of the vending machine 10, the CPU 31 causes the communication control unit 37 to execute a process of disconnecting a call established with the wireless communication terminal (step S2).
3).

Next, the CPU 31 of the management server 30 searches the start time 35c and the end time 35d of the telephone number-specific TS table 35T shown in FIG. Vending machine ID 35b in which communication was possible at the time
Is extracted. Thereby, the CPU 31 of the management server 30
Specifies which vending machine the downloaded vending machine 10 is (step S24). More specifically, for example, if the time from the start of the download to the end of the download is from 0:05 to 0:15, the communication can be performed from 0:00 to 0:55 shown in FIG. Vending machine 10a whose vending machine ID is "111A"
Is specified as the vending machine to be downloaded.

The CPU 31 of the management server 30 stores the result of the download processing in association with the specified vending machine 10 (step S25). Specifically,
For example, when downloaded to the vending machine 10a, the name of the program and data downloaded to the vending machine 10a, the start and end times of the download,
In addition, a processing flag indicating whether or not the download has been normally completed is stored as a download processing result.

Here, for example, as shown in FIG.
Since there are a total of three wireless communication terminals of the vending machine 10 to which "090-9999-1111" is given as a telephone number, the management server 30 needs to repeat the download at least three times. As shown in FIG.
Each vending machine changes the communication available time every hour. Therefore, if the management server 30 downloads three times every hour, the management server 30 downloads to all wireless communication terminals of the vending machines. It becomes possible.

The processing performed in step S24 of this operation example when the management server 30 specifies the downloaded vending machine 10 is described in step S24.
At 21, it may be performed before the management server performs the sending process to the vending machine.

Further, the method for realizing various functions provided in the vending machine 10 and the management server 30 according to the above-described embodiment uses a program for executing various functions performed in the vending machine and the management server. The invention is not limited to the case where the functions are stored in advance in the vending machine and the management server. For example, even when the program is read and installed from a recording medium on which the program is recorded and installed and realized, or when the program is downloaded to a vending machine or a management server through a telecommunication line and then installed and realized. Good.

[3] Effects of the Embodiment As described above, in the present embodiment, a plurality of vending machines can be provided with a communication device to which the same telephone number is assigned, so that the telephone number and the radio band are exhausted. And the problem of lack of communication facilities can be alleviated.

Further, when a plurality of vending machines are provided with communication devices to which the same telephone number is assigned, a reduction in a communication contract fee can be expected, and the realization of the vending machine management system according to the present embodiment is further accelerated. Can be a factor that causes

[4] Modifications of Embodiment In the above-described embodiment, the case where the present invention is used for managing a vending machine is described. However, the method of using the present invention is not limited to this. Absent. For example, it may be used to limit the time zone during which a mobile phone or a simplified mobile phone can be used. For example, when the working hours of a company employee are two shifts: day shift and night shift, a mobile phone or a simplified mobile phone with the same telephone number is used for day shift and night shift. Power ON / O according to working hours
It is possible to set so that the FF switches.

Further, in the above-described embodiment, the ON / OFF of the power of the wireless communication device is switched according to the time zone. However, the method of switching the ON / OFF of the power of the wireless communication device is not limited to this. For example, power ON / OFF may be switched on a daily basis or a weekday basis. As a result, when a person who works on a specific day or a specific day of the week is switched, each worker can carry a mobile phone or a simplified mobile phone with the same telephone number, Can be set to switch between ON and OFF.

Further, in the above-described embodiment, the switching of the wireless communication terminal between the communicable state and the non-communicable state is performed by turning on / off the supply of the power supply voltage to the wireless communication device. However, in addition to this, various switching methods are conceivable. For example, a mobile communication wireless terminal such as a mobile phone transmits and receives a control signal for location registration to and from a base station of a mobile communication network, and thus transitions to a standby state and becomes communicable. Therefore, the wireless communication terminal is configured to transmit and receive the control signal for the location registration only in the communicable time zone and not to transmit and receive the control signal in the time zone other than the communicable time zone. Is also good. In this case, since the plurality of wireless communication terminals having the same telephone number do not overlap with each other in the communicable time periods stored therein, these wireless communication terminals simultaneously transmit and receive control signals for location registration. Nothing to do. Therefore, it is guaranteed that there is only one wireless communication terminal corresponding to one telephone number when viewed from the mobile communication network side.
