No additional work is required. Furthermore, if the auction operation device 12 is connected to an external communication means such as the Internet, the auction can be performed simultaneously on a worldwide scale without being limited to the auction site.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG.

The second embodiment differs from the first embodiment in that a plurality of, for example, first and second master station radios 13a and 13b are provided as shown in FIG.
The communication areas 16a and 16b defined by the antennas 31a and 31b of the 3b are set.
A directional antenna is used as the antenna 25 of the fifth embodiment.

According to the second embodiment, the same effects as those of the first embodiment can be obtained, and the master station radio 13
a, 13b by restricting the communication areas 16a, 16b, giving the antenna 25 of the buyer wireless terminal 15 directivity, and directing it toward the antennas 31a, 31b of the master station radio 13 to communicate with, The data processing amount of each of the master station radios 13a and 13b can be reduced.

In the third embodiment, the communication areas 16a and 16b of the master station radios 13a and 13b are partially overlapped as shown in FIG. 5 in the second embodiment. The master station radios 13a and 13b are either time-division multiplexed access (TDMA) for shifting the communication time with the adjacent master station radio or frequency division multiplexed access (FDM) for shifting the frequency.
A) Alternatively, code division multiple access (CDMA) that shifts communication codes in digital communication is used to prevent simultaneous reception of signals from a plurality of buyer wireless terminals 15 in the overlapping communication area 16c.

According to the third embodiment, a plurality of master station radios having a relatively small communication area are used, the communication areas of the respective master station radios are partially overlapped, and time division multiplexing connection and frequency division multiplexing are used. By performing the connection or the code division multiple access, it is possible to make the entire area of the auction venue a communication area without simultaneously receiving data from the buyer wireless terminals 15 in the overlapping communication area. Therefore, the buyer can use the buyer wireless terminal 15 while arbitrarily moving it without fixing it.

(Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to FIG.

The fourth embodiment is different from the second or third embodiment in that the buyer wireless terminal 15 is provided as shown in FIG.

Device 13.

On the other hand, when the master station radio 13 receives the data transmitted from the buyer radio terminal 15, the master station radio 13 compares the successful communication from the time when the first communication is established to the time after the communicable time by retransmission, and receives the data. The time data in the data has a function of validating the earliest communication and outputting the communication to the human-made operating device 12.

When the buyer wireless terminal 15 and the cell phone operator 12 communicate with each other via the master station radio 13, the master station radio 13 receives signals from a plurality of buyer wireless terminals 15 almost simultaneously. In this case, collision avoidance of data for which communication has failed is performed, and data is retransmitted. If another master station radio 13 receives a signal from the buyer wireless terminal 15 during this time,
Although the buyer wireless terminal 15 during retransmission presses the switch 21 earlier, the buyer wireless terminal 15 that has successfully communicated first has priority.

In order to solve such a problem, in the fourth embodiment, the time when the switch 21 is pressed is included in the transmission data from the buyer wireless terminal 15, and the first communication succeeds in the master station radio 13. Then, after the time when the communication by retransmission ends, the communication in which the switch 21 is pressed at the earliest time in the successful communication is enabled, thereby preventing the communication order from being reversed.

As described above, according to the fourth embodiment, the current time at which the switch 21 was pressed is included in the transmission data of the buyer wireless terminal 15, and after the communication with the master station radio 13 is established, retransmission is performed. By enabling the communication with the buyer wireless terminal 15 whose switch 21 has been pressed the earliest in the communication succeeded by the time when the communication ends, it is possible to reliably prevent the communication order from being reversed due to data retransmission. Can be.

[0032]

As described above, according to the present invention, data transmission is performed by wireless communication.
When installing a new automatic auction system in a venue that used to perform auction by hand or voice, you can participate in auction at any position. This eliminates the need for large-scale construction such as a stepped field or a designated desk, thereby shortening the construction period and reducing costs. In addition, when adding a buyer wireless terminal at a venue where this system is adopted, it is only necessary to increase the number of buyer wireless terminals within the communication area of the master station radio. Do not need.

Further, according to the present invention, since a plurality of master station radios connected to the cell phone operating device are provided and the communication area of each master station radio is limited, the data processing amount of each master station radio is reduced. The power consumption can be reduced while the power consumption can be reduced.

Further, the present invention uses a plurality of master station radios having a relatively small communication area, partially overlaps the communication area of each master station radio, and performs time division multiple access, frequency division multiple access, or By performing code division multiple access or the like, it is possible to use the entire communication area of the auction site as the communication area without simultaneously receiving data from the buyer wireless terminals in the overlapping communication area.

Further, according to the present invention, the buyer wireless terminal is provided with a clock section for clocking the current time, and when the switch is pressed, the current time clocked by the clock section is added to the transmission data. Since it is transmitted to the master station radio,
In the master station radio, after the time when the first communication succeeds and after the time when the communication by retransmission ends, the communication with the earliest time when the switch was pressed in the successful communication is enabled to prevent the communication order from being reversed. Can be.
