BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information collection system of a vending machine that wirelessly performs collection and management of information necessary for inventory management of goods, maintenance of gas, and the like.

In the conventional management system of this type of vending machine, as shown in FIG. 6, data is transmitted from the vending unit 1 having the data processing management function built therein into the tele terminal base station 100 or the telephone line 200. Through the VAN and the center 300, and perform value-added services such as data analysis in the VAN center 300, and then to the host computer 400 of the owner of the vending machine or the personal computer 500 of the sales office. It is supposed to collect information online to send the necessary data.

In this way, the data collected from the auto sales basic body 1 is transmitted to the nearest circuit 600, for example, so that the goods can be replenished by the routeman when it relates to the presence or absence of the stock of goods. It is.

In addition, in the related art, when collecting information from a plurality of vending machines distributed at each point, it is also considered to transmit and receive to a specific low-power radio unit built in each vending machine main body 1, For example, it is disclosed also in Unexamined-Japanese-Patent No. 2-105699.

Then, the transmitter and the receiver are sent to and received from the wireless unit. As the data is collected, the data from the wireless unit is analyzed to determine the state of each vending machine. have.

In a conventional information gathering system using such a radio, when collecting vending machine information outside the receiving range, the information of the intended vending machine is collected by using a radio of the vending machine within its receiving range as a repeater. It is known.

However, in the case of collecting information by relaying the information collecting system of the conventional vending machine, that is, the vending machine within its own receiving range, not only the relay route must be stored in the data collecting device in advance, Each time you move to another location, you must set up a relay route.

In addition, information collection by the data collection device is also possible only at the place where the route is set, and there is a problem that communication is virtually impossible because communication with the first relay is not possible at other places.

It is an object of the present invention to collect information from a vending machine that allows the communication to be performed without setting a relay route in advance, when collecting information by relaying a vending machine within its reception range. To provide a system for collecting information.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention provides the means for sending and receiving which is a vending machine main body with a built-in data processing function, and a wireless unit which is connected to the data management processing function of this vending machine main body, and transmits and receives information. An information collecting system of a vending machine, which collects information of a vending machine main body for another purpose by using a data collecting device, and uses the transmitting and receiving means as a repeater within its receiving range. When the apparatus performs the same information communication to each of the surrounding vending machines at the same time, and judges that each vending machine main body that has received the same information communication at the same time is not the contents of communication to the self, the vending machine main body is used as the relay station. While communicating the same information at the same time, it is made from this relay vending machine. The vending machine main body having received the same information and determined to be the contents of communication with the self is to communicate with the data collection device through the relay vending machine main body which is the source.

That is, in the present invention, when the data collection device performs the same information communication to each of the surrounding vending machines at the same time, and it is determined that the main body of the vending machine that has received the same information communication at the same time is not the contents of communication with the self, The main body of the vending machine communicates with the same information in the same way as the relay station, while the main body of the vending machine that receives the same information from the relay vending machine body at the same time and judges that it is the contents of communication with the self, Since the vending machine communicates with the data collection device, the relay route does not need to be stored in the data collection device in advance when the vending machine is installed, and each time the vending machine moves to another location. There is no need to set up a relay route.

EXAMPLE

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 4 to 5.

FIG. 1 shows a simulated system configuration of a wireless data collection system according to the present invention, and 1A to 1D in the drawings are the vending machine main bodies distributed in each point.

Each of these auto sales basic bodies 1A to 1D includes, for example, a data management processing function for automatically selling a variety of canned goods such as soft drinks, product management data on stocks or sales of goods, and maintenance of failures. A function of managing information such as management data is built in, and radio units 2A to 2D as transmission / reception means for communicating with the data collection device 10 are provided.

Each of these radio units 2A to 2D has device numbers 01 to 04, and is called a control channel on the basis of the contents of data used when performing communication as shown in FIG. The specific frequency is used to send the host station number and the counterpart device number and information for exchanging data using a certain frequency.

At this time, the opposite wireless unit receives the contents of the counterpart device number, determines whether it is calling or not, and receives data at a specified frequency. 00 "is inputted with the device number of the vending machine main body or vending machine NO. To be collected in user data.

Fig. 3 shows the contents of the user data in response, and the radio unit at the time of relaying adds the local device number to this data and sends it to the radio unit in the previous step.

In this case, the data collection device 10 decides the route based on the contents of the response data finally sent, and performs subsequent data communication processing.

4 shows a connection sequence when data is collected by a predetermined vending machine. For example, when data is collected by the vending machine body 1D, the same information from the data collection device 10 is the same. It is received by the main body 1A and the vending machine main body 1B, and is each sending the same information simultaneously.

Since the same information communication by the auto sales main body 1A and the auto sales main body 1B is received at the same time, it is assumed that the call is not made twice because it is the same contents as the one called.

Finally, the contents of the contents called by the auto sales main body 1B are received by the auto sales main body 1C. When the auto sales main body 1D receives, the auto sales main body 1D sends the response data to the auto sales main body ( Call towards 1C).

Also, the auto sales basic body 1C transmits the response data to the auto sales main body 1B, and the auto sales main body 1B transmits the response data to the data collection device 10, and at the same time, adds its own device number and finally collects the data. The route set this time is to be entered into the response data received by the device 10.

5 shows a flowchart of communication subroutines in each of the radio units 2A to 2D of the automats 1A to 1D.

However, the above-mentioned data collection system of the present invention first communicates the same information from the data collection device 10 all at once. In the same information, the special code is sent to the counterpart device number at the time of carrier sense, and the device number or vending machine of the vending machine is added to the user data.

In the case of determining that the user data is not the contents of oneself, the autonomous vending bodies 1A to 1D that have received the same information at the same time communicate the same information at the same time, while the contents of the contents are the same. Communication continues and the source communicates with the source.

Such operation is sent to the data collection device 10, the route data led to a certain route is added to the user data, and the subsequent exchange is performed by relaying using the returned route data.

As will be apparent from the above description, the present invention provides that the data vending device performs the same information communication with respect to each of the surrounding vending machine main bodies, and that the vending machine main bodies receiving the same information communication at the same time are not the communication with them. At the time of judgment, the vending machine main body communicates the same information simultaneously as the relay station, while receiving the same information from the relay vending machine main body at the same time, and judges that it is the contents of communication there. Cause of transmission Because the relay vending machine communicates with the data collection device, it is not necessary to store the relay route in the data collection device before installing the vending machine as before. There is no need to set a relay route every time .

Moreover, this enables communication even if the data collection device is moved, and furthermore, communication can be carried out using a relay vending machine having good initial communication conditions there.
