Description

Dedicated Test Equipment and Method of TQM

The present invention relates to a dedicated test apparatus and method for a machine control unit (TQM), which is an AFC system equipment, and a machine control unit (e.g., a ticket machine, a fixed ticket machine, a payment machine, a ticket machine, etc.) The present invention relates to a dedicated testing apparatus and method for a main machine part (TQM) of a vending machine, which makes it possible to repair and check the abnormality of each function.

In general, the subway, which has to deal with a large number of users, is equipped with an AFC system that allows all the tasks such as ticketing, ticketing, billing, and settlement to be done unattended. Equipment used in the AFC system includes terminals such as a general ticket vending machine (ATVM), flat ticket vending machine (ATF), payment machine (AAM), ticket vending machine (TOM), etc., which have a basic function of ticket sales. There is equipment, and these terminal equipments are connected to the upper level reverse computer system by communication line. In addition, these terminal equipments include unit devices such as a main control unit (TQM) and a ticket issuing unit (TIU). In addition, a fare-related unit device such as a coin processing unit or a bill processing unit and an operation for allowing a passenger or a station employee to operate the terminal equipment It is provided with a panel and the like.

1 schematically illustrates a configuration of a conventional machine main control unit (TQM) to which a test apparatus according to the present invention is applied. Among the unit devices described above, the main control unit (TQM) 1 is mounted inside terminal equipment such as a ticket machine or ticket machine, and operates other unit devices such as a ticket issuing unit (TIU), a coin and bill processing unit, and the like. It has a role to control. In addition, the TQM not only collectively controls the operation of each unit device constituting one terminal device, but also is located between each unit device and a higher level, and information collected from each unit device, for example, ticket sale completion information, It also plays a role of sending error information to the upper level when the ticket is released.

As shown in FIG. 1, the TQM 1 includes all the unit devices constituting one terminal equipment such as a general ticket machine, for example, a journal printer unit, a station attendant panel unit, a front panel unit, a bill processing unit, a coin processing unit, and a ticket issuer. The unit device connection port 10 connected to the TUI, the station for setting the station or the section, the section setting switch 14, the switch 16 for setting the test mode and the reset key 18, etc. It is equipped with several switches. In addition, there is provided a seven-line display device 30 for displaying the communication status and the occurrence of an error with the unit device currently being controlled. In the center of the board, a unit device controller 20 and a communication controller 22 made of integrated circuit chips are disposed together with the unit device control ROM 24 and the communication control ROM 26, respectively. As shown in FIG. 1, three serial ports 40 RS3, RS1, and RS2 are installed in sequence.

2 schematically illustrates the connection configuration of equipment for testing the conventional TQM board (1). As shown, conventionally, in the machine main control unit (TQM) 1 as described above, the first computer 42 is connected to RS1 of the serial port 40, and the second computer 42 is connected to RS2. After connection, the two control ROMs 24 and 26 are replaced with test ROMs 24 'and 26', and 5V power is applied to operate the test programs embedded in the first and second computers 42 and 44. Check the abnormality caused by the control function of the TQM. In the case of testing the communication function of the TQM, the first computer connected to the RS1 is connected to the RS3, and the same method is checked for abnormality. When an abnormality occurs, it is displayed by a test program running on the first and second computers so that the operator can recognize which function has occurred. If a fault occurs, the circuit of the board may be checked and repaired using a conventional repair tool.

However, in the conventional test work as described above, there is a problem that the work is cumbersome and complicated because there is no separate dedicated repair apparatus. In other words, it was possible to easily check each function of the main machine (TQM) of the vending machine and find out whether there is more than that. However, when an abnormality occurs in any function and a repair is required, a normal repair tool must be used.

Therefore, the present invention can be arranged to easily test the main machine control unit (TQM) to be repaired, dedicated to the machine main control unit (TQM) that can be easily tested and repair work can be made at the same time as the test can be repaired Its purpose is to provide a test apparatus and method.
