Abstract

PURPOSE:To enable reduction in the testing time with inexpensive manufacture of the whole equipment, by dividing the function of a large and sole electronic computer system into several parts to be shared by a plurality of electronic computer subsystems and electronic computer systems. CONSTITUTION:For example, when measuring the voltage of an controller of an electric car 1 at a certain measuring point, a first electronic computer subsystem 7A shares a function of a series of processing sequence in which a digital output for test preparation is applied to a test execution unit 2 to read an voltage value resulted from a test with the test execution unit 3. A second electronic computer subsystem 7B shares an interface function as switch or the like by controlling an operator 4 and a third electronic computer subsystem 7C does a function of editing a test data to print a achievement of tests with a printer 5. In this manner, the subsystems 7A-7C can be operated individually by dispersion of the function. Besides, an electronic computer system 6A executes the test procedure sequentially to administer the subsystems 7A-7C on a simple command.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a comprehensive train testing device for testing (inspecting) single-vehicle trains or multi-car trains.

In particular, it relates to the electronic computer system.

[Conventional technology]

FIG. 2 shows, for example, [Mitsubishi Electric Branch JVo1. Da9. /16
This is a block diagram showing the conventional train general test equipment published in 3 (/yts) K. In Figure 2, (1) is a multi-car train, and (2) is this train (1). A test execution device that supplies power, an air source, and various signals to make the train (1) ready for testing; [3) is a test execution device that receives and stores test signals from the train (1); ) is the operation panel, (S
) is the printer that prints the test results, (6) is the test execution bag f (2) and (J).

The only electronic computer system that controls the operation panel (4I) and printer is a general-purpose computer larger than a minicomputer.

Since the conventional electric train comprehensive test equipment is configured as described above, when the electronic computer system (6) receives a lift start command from the operation panel, it runs the test execution device (2) according to a pre-programmed test procedure. ).For example, when measuring the voltage at a measurement point consisting of a control device (not shown) mounted on a train (/), computer system A (6) outputs a test instruction to A digital output for preparation is given to the test execution device (2), and the test execution device (2) that receives this supplies a signal to the train (1) to make the train (1) ready for testing (measurement). Next, the computer system (6) outputs a test start command to the test execution device [1(s), and the test execution device (3) that receives this command sequentially tests the train (1) through the procedure. When the test is completed, the electronic computer system (6) stores the test data obtained from the train (1).
(not shown), edit the test data, and print the test results on the printer (S).

[Problem that the invention seeks to solve]

In conventional computer systems, all functions are centrally managed, so it is necessary to use a high-performance, high-capacity computer, such as a general-purpose computer larger than a minicomputer, and the cost is high. Since all the processing was done by a computer, there were problems such as it was difficult to process each function in series, and it took time.

This invention has been made to solve the above-mentioned problems, and aims to provide a comprehensive electric train test system that can reduce costs, perform parallel processing, and is not time consuming.

[Means for solving problems]

The electric train comprehensive testing device according to the present invention includes a first computer subsystem (7A) for controlling a test execution device [(2) and (3) for testing a train (1), and an operation panel ( a second computer subsystem (7B) for controlling the printer (5); a third computer subsystem (7C) for controlling the printer (5); The system is equipped with a computer system for integrating the computer subsystems of the computer system.

[Effect]

In this invention, the functions of a large and only computer system are divided into multiple units and shared among multiple computer subsystems and computer systems, so a small-capacity computer can be used.

), the test execution device (2) is given a test preparation digital output, and the test execution device (3) is connected to the train (1).
The function is to carry out a series of processing sequences for reading the tested voltage values, that is, test data. The second computer subsystem (7B) controls the operation panel and shares the interface functions of its switches, display device, etc. (not shown).The third computer subsystem (7B)
