M, 3 is a RAM, which includes reception information, ID of the wireless station of the information request destination, ID of the wireless station of the transmission destination, ID of the own station,
The wireless station abnormality detection time is stored. The radio station abnormality detection time refers to the time when transmission is determined to be abnormal when a line is not connected even if communication is attempted continuously for a certain period of time. Reference numeral 4 denotes a self-machine information detecting unit for detecting information such as sales and failures in the own vending machine, and reference numeral 5 denotes a clock for measuring time. Reference numeral 6 denotes an optical interface for inputting the ID of the wireless station of the information request destination, the ID of the wireless station of the transmission destination, the ID of the own station, and the transmission abnormality detection time.
X and Y are wireless modems for transmitting and receiving information.

In the information processing apparatus C, 7 is a CPU, 8
Is a ROM, 9 is a RAM, 10 is an interface, and 11 is a data processor connected to the interface 10. Z is a wireless modem of the information processing apparatus C.

[0010] Hereinafter, the information of the vending machine B is transferred to the vending machine A.
Is transmitted to the information processing apparatus C as a wireless relay station. For vending machines A and B,
The information requesting wireless station ID (vending machine B in the vending machine A) and the transmitting wireless station I
D (the vending machine A for the vending machine B, the information processing device C for the vending machine A), the own station ID and the radio station abnormality detection time are input in advance. Vending machine A is R
An information request signal is transmitted to the vending machine B via the wireless modem X according to the wireless station ID of the information request destination stored in AM3. When the vending machine B receives the signal via the modem Y, the vending machine B receives the information detected by the own machine information detecting section 4 in the vending machine B together with the wireless station ID of the vending machine via the wireless modem Y. The information is transmitted to the vending machine A according to the ID of the information transmission destination radio station. The vending machine A stores the information received from the vending machine B and the wireless station ID of the communication destination in the RAM 3. If the information cannot be received by one information request, this operation is repeated. Further, the own machine information in the vending machine A is detected by the own machine information detecting unit 4 and is stored in the RAM.
3 is stored.

On the other hand, the vending machine A compares the wireless station ID of the information request destination stored in the RAM 3 with the wireless station ID obtained by this information request to determine whether or not communication has actually been performed. However, if there is no communication based on the time measured by the clock 5 even when the abnormality detection time is exceeded, the wireless station is determined to have a transmission abnormality.

On the other hand, in the information processing apparatus C, the information requesting wireless station I stored in the RAM 9 is stored at a certain time interval.
Based on D, a request for information is made to the vending machine A via the wireless modem Z. In this case, since the information request destination wireless station ID is for the vending machine B, the vending machine A receives the information received from the vending machine B (when communication between the vending machines A and B cannot be performed, a transmission error occurs. Information is included)
The information is transmitted to the information processing apparatus C according to the ID of the information transmission destination radio station.

The information processing apparatus C checks whether or not the information received from the vending machine A includes an information transmission abnormal radio station ID, and if so, transmits the ID information to the interface 10. The data is output to the data processor 11 via a CRT display (not shown).

FIG. 4 shows an embodiment according to the second invention. 4 is different from FIG. 3 in that the transmission abnormality is not determined by the CPU 1 of each vending machine, but is determined by the CPU 7 of the information processing apparatus C. 12 and a data processor 1
In step 1, the wireless station IDs of all vending machines received by the information processing apparatus C, the wireless station IDs of the information request destinations, and the transmission abnormality detection time are input and stored in the RAM 9.
Here, a case where the information of the vending machine B is transmitted to the information processing apparatus C via the vending machine A will be described.

As in the previous embodiment, the information of the vending machine B is transmitted to the vending machine A together with the ID and stored in the RAM 3. If the information is not transmitted properly, this operation is repeated. On the other hand, the information processing device C requests the vending machine A to transmit information according to the wireless station ID of the information request destination stored in the RAM 9. Thereby, the vending machine A
When the information from the vending machine B is not stored in the RAM 3, the self-station information is added to the self-station information detected by the self-station information detecting unit 4 and transmitted to the information processing apparatus C. The information processing device C extracts all the wireless station IDs from the information received from the vending machine A and stores them in the RAM 9. Then, the information processing apparatus C periodically, according to the clock of the clock 12,
By comparing all wireless station IDs stored in the RAM 9 with IDs extracted from the transmission information, IDs not included in the transmission information are confirmed, and the IDs are determined during the transmission abnormality detection time. If not detected, the wireless station with that ID is determined to be a transmission error and output to the data processor 11.

[0016]

As described above, according to the present invention, in a system in which information of a vending machine can be transmitted in real time using a specific low-power radio as a transmission medium, an abnormality in information transmission is detected and the detected location is detected. Is output together with the ID indicating the error, so that the location where the abnormality has occurred can be easily specified,
Therefore, it is possible to quickly recover from the abnormal location, and it is possible to minimize a state in which important information cannot be transmitted.
