Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a wireless automatic auction system, particularly in an auction market for livestock, etc., which uses a wireless press titanium switch, which is a small transmitter, to indicate the purchase intention of a purchaser. -Relates to a wireless automatic auction system that emits weak radio waves when turned off, which are received by a receiving device and output to an operating device.

[Conventional technology]

Traditionally, at auctions of livestock such as cows and horses, producers or auction market staff pull the livestock in front of a large number of buyers at the auction market. Deals were concluded one after another through a mixture of loud shouts and hand movements. It is easy for mistakes to occur through shouting and hand-to-hand exchanges during such quarrels, and there is a danger that the buyer's intentions will not be clearly communicated to the seller.

In addition, to solve these problems, the seller can connect the push button switch to the operating device by wire, and check whether it is on or off by checking the blinking monitor lamp on the operating device.
An auction system has also been proposed in which the price is increased until the winning bidder is reached, and then the winning bidder is made at the end.

However, such systems do not allow purchasers to leave their assigned seats, which are equipped with push-button switches, and therefore require them to directly touch the animals to check their health, coat, meat, etc. That was difficult. In particular, dairy cows, beef cows, racehorses, etc. are extremely expensive, so it is necessary to carefully examine them and observe them closely before making a purchase decision.

[Problem that the invention seeks to solve]

In order to solve the above-mentioned problems, the present invention enables buyers to convey their intentions even while moving to the trading floor where products are bought and sold in the auction market.

[Means to solve the problem]

Therefore, in the present invention, the push-button switch is made wireless so that the purchaser can move freely.

Purchasing intentions can be communicated through the on/off operation of a wireless pushbutton switch.

Thus, according to the present invention, in the auction market for livestock etc.
A purchaser's purchase intention is transmitted by emitting weak radio waves by turning on and off a large number of wireless pushbutton switches, which are then received by a double suit 'e-heteroda ()-in receiving device, and the weak radio waves are transmitted. After identifying the wireless pushbutton switch that was fired.

A wireless automatic auction system is provided that is characterized by outputting to an operating device.

[Effect]

The system according to the present invention is configured as detailed below, so that even though the radio waves emitted from the wireless pushbutton switch are weak, the receiving device can receive all of them and reliably identify them. In addition to being able to reliably and accurately grasp the purchasing intentions of buyers participating in the auction, it is also possible to conduct the auction smoothly.
