DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a start-up inspection method for a wireless data transmission apparatus for transmitting data between a base station and a plurality of mobile stations.

[0002]

2. Description of the Related Art Wireless data transmission systems for transmitting data between a base station and a plurality of mobile stations are used in many industries. Such a system has an advantage that information can be transmitted quickly and work can be saved and rationalized. The base station is a radio station installed in a user's office or the like, and supervises and manages the mobile station, and collects commands and information. The mobile station is installed in a car or the like.

Each of a plurality of mobile stations is provided with an individual code or the like, and can be individually called. Also, a plurality of mobile stations are given the same user code for the same user. Therefore, the base station can call the mobile station individually or simultaneously from the same user code. In such a wireless communication system, a plurality of channels can be used, and an empty channel is allocated for communication. In addition, a communication time limit is set so that many users can communicate fairly, and a communication area is also limited. Usually, the base station communicates with each mobile station in a certain order to transmit information.

[0004]

In the conventional wireless data transmission apparatus system, the inability of the mobile station's wireless data transmission apparatus to perform communication due to malfunction or the like is only when it is known that the base station cannot call and communicate with the mobile station. You can check. However, the mobile station may have a poor communication state depending on locational conditions, so the base station needs to call and confirm the mobile station many times. For example, when there is no response to a predetermined number of calls, it is determined that the operation is malfunctioning, and the process proceeds to the next mobile station call. Therefore, when an operation failure occurs on the mobile station side, the base station side becomes extremely inefficient in business.

An object of the present invention is to confirm the operation failure of a mobile station in advance, eliminate the waste of time caused by calling a mobile station having an operation failure, and improve the efficiency of business.

[0006]

According to the present invention, there is provided a method for performing a start-up inspection between a base station and a plurality of mobile stations, comprising the steps of: turning on the power of the mobile station within a distance where wireless data transmission can be reliably performed; The base station performs a predetermined transmission test to determine the operation state, and the base station displays the mobile station whose operation state is determined to be abnormal as a result of the transmission test, and performs data transmission with the mobile station. This is a method for starting inspection of a wireless data transmission device, characterized in that it is not performed.

[0007]

According to the present invention, a start-up check is performed between a base station and a plurality of mobile stations in order to confirm in advance the malfunction of the mobile station. As a method of the start-up inspection, a mobile station is turned on at a distance where wireless data transmission can be reliably performed, and a predetermined transmission test is performed between the mobile station and the base station to determine a malfunction. As a result of the transmission test, the base station displays a mobile station whose operation failure is determined to be abnormal, and prevents data transmission with the mobile station. Therefore, since the operation failure of the mobile station can be confirmed in advance, it is possible to eliminate waste of time caused by calling the mobile station having the operation failure.
