[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an inspection method and an inspection device for a wireless communication device such as an infrared light emitting / receiving device mounted on a computer.
[0002]
[Prior art]
In recent years, downsizing of computers has progressed, and notebook computers that exhibit light start-up power have become widespread. The range of use of computers extends from the inside of the company to the outside, and data is exchanged between a notebook computer taken outside and a host computer in the company, and various information is managed in an integrated manner. In addition, various information is shared by exchanging data between notebook computers taken outside.
[0003]
Data exchange between such computers has changed from a method using a recording medium such as a floppy disk to a method of transmitting and receiving data using a communication cable. In response to corporate space-saving needs, computers are becoming smaller and thinner with both high performance and portability, and the need for communication cables to send and receive data has become troublesome. Transmission / reception has shifted to wireless communication using infrared rays or the like.
[0004]
In wireless communication using infrared rays, an infrared receiving / emitting device as a wireless communication device is built in the computer body without connecting multiple computers with cables, and data is transmitted from the light emitting elements in the infrared receiving / emitting device. Then, data exchange is performed by receiving the previous data by the light receiving element of the infrared light receiving and emitting device built in another computer. Thereby, the troublesomeness using a communication cable is eliminated.
[0005]
Generally, the data communication method used in data communication is the IrDA (Infrared Data Association) standard, and the data communication means built in the notebook computer is an infrared light receiving and emitting device compliant with the IrDA standard. In the IrDA standard, data is transmitted and received at a data transfer rate of 2400 bps to 4 Mbps, and high-speed data communication of 4 Mbps at the maximum is possible.
[0006]
Infrared light emitting / receiving devices are manufactured and inspected by device manufacturers. In the inspection, the inspection items decided in the manufacturer are input to the inspection tester, and each characteristic inspection of the apparatus is performed. The infrared light emitting / receiving device that has been inspected is shipped to a computer manufacturer and mounted in the computer by the manufacturer.
[0007]
FIG. 4 is a schematic diagram of an inspection apparatus for a conventional infrared light receiving / emitting device, and FIG. 5 is a flowchart of an inspection method for the conventional infrared light receiving / emitting apparatus.
[0008]
As shown in FIG. 4, the conventional inspection apparatus for infrared light receiving and emitting devices is composed of two computers A and B. The computer A has a board 2 with a socket into which the infrared receiving and emitting device 1a to be inspected is inserted. The computer B is equipped with an infrared light emitting / receiving device 1b. These two computers A and B are arranged approximately 1 m apart from each other with the infrared light receiving / emitting devices 1a and 1b facing each other, and the infrared light receiving / emitting device 1a to be inspected is inserted into the board 2 with a socket of the computer A. The infrared light emitting / receiving device 1a is inspected based on the flow shown in FIG.
[0009]
For example, when the inspection based on the IrDA 1.1 standard is performed, the data transfer speed, which is one of the inspection items of the wireless communication system, is 9 types of 2400, 9600, 19200, 38400, 57600, 115200, 576000, 1152000, 4000000 bps. The computer A and the computer B communicate with each other at each of these data transfer speeds for inspection.
[0010]
As shown in FIG. 5, in step 31, the data transfer speed for inspecting the infrared light emitting / receiving device 1a is determined, and the data transfer speeds of the computers A and B are set. In step 32, data is transmitted from the infrared ray receiving / emitting device 1a of the computer A. In step 33, this data is received by the infrared ray receiving / emitting device 1b of the computer B, and the received data is transmitted again from the infrared ray receiving / emitting device 1b of the computer B. In step 34, this data is received by the infrared ray receiving / emitting device 1a of the computer A, the received data is compared with the original data, a bit error is confirmed, and the quality of the infrared ray receiving / emitting device 1a is determined. And in order to raise the reliability of the apparatus to ship, these steps 31-34 are repeated several times for every data transfer rate.
[0011]
[Problems to be solved by the invention]
According to such a conventional inspection method, it is necessary to set the data transfer speed for each of the two computers A and B, and the inspection is performed while moving by one person between the computers A and B arranged about 1 m apart. It is difficult to do this, and usually two people are placed in each computer A and B for inspection. Therefore, problems such as labor costs have arisen.
[0012]
Further, since it is necessary to inspect a plurality of types of data transfer rates, the data transfer rate settings of the two computers A and B are changed each time. Therefore, when inspecting a plurality of types of data transfer rates, it is necessary to operate and monitor the two computers A and B throughout the inspection, and a considerable amount of time and labor are consumed.
[0013]
Furthermore, when performing inspections based on the IrDA 1.1 standard, there are nine types of data transfer speeds of 2400 to 4 Mbps, and repeated inspections are repeated for each data transfer speed in order to improve the reliability of the apparatus. Is difficult with conventional methods.
[0014]
Further, the infrared light emitting / receiving device 1a differs depending on the computer on which the method of use is mounted, and the inspection contents decided inside the manufacturer of the infrared light emitting / emitting device 1a do not necessarily correlate 100% with the usage state. For this reason, it is better to inspect it by mounting it on the computer to be used. However, the manufacturer of the infrared light receiving / emitting device 1a has no target computer, and the infrared light receiving / emitting device 1a is mounted by the computer manufacturer. Yes. Therefore, it is difficult for the manufacturer of the infrared light emitting / receiving device 1a to perform a complete inspection according to various usage methods, and it is difficult to completely eliminate the inspection omission.

Accordingly, an object of the present invention is to provide a wireless communication apparatus inspection method and inspection apparatus capable of automatically inspecting a wireless communication apparatus to be inspected by an arbitrary wireless communication system.
