Abstract

PURPOSE:To achieve a higher efficiency of inspection work with a relatively simple construction by additionally storing a series of procedures into a memory for inspection procedures when a fault is found in a circuit of an electronic equipment. CONSTITUTION:A procedure program stored into a memory 4 is executed to change the operation mode when no fault is found and inspection is carried out in the desired procedure as specified sequentially with an operation key 2 and a display 3 by a worker. When a fault is found, a series of inspection procedures so far stored sequentially into the memory 5 are additionally stored into a program having specified inspection contents of the memory 4 as procedure program. Subsequently, identical fault can be detected easily by executing the specified series of procedure programs including that being added.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inspection device, and more specifically,
The present invention provides a device that is effective in finding faults in circuits of electronic devices.

Generally, when discovering a fault in the circuit of an electronic device, a person who understands the circuit refers to the circuit diagram and performs the test according to an arbitrary procedure, or a test is created in advance for each test content. The inspection is carried out according to the established procedure program.

However, the former method relies heavily on experience and has the disadvantage that it takes a considerable amount of time to become proficient. On the other hand, according to the latter method, the check can be carried out step by step according to the steps shown by the program. It is impossible to create a program that covers all of the problems, and the former method has to be followed each time for failures that are not programmed.

The present invention solves these conventional drawbacks, and includes a first memory that stores procedure programs created in advance for each inspection content, and a second memory that sequentially stores inspection procedures performed in arbitrary steps. If the procedure program stored in the first memory is executed and no fault is found, the inspection is carried out in any procedure until the fault is found, and when the fault is found, it is This method is characterized in that a series of test procedures that have been sequentially stored in the second memory are additionally stored in the first memory using a procedure program.

Hereinafter, a detailed explanation will be given using the drawings.

The drawing is a block diagram of essential parts showing one embodiment of the present invention, in which 1 is a CPU, 2 is an operation key, 3 is a display, 4 is a first memory, 5 is a second memory, and 6 is a The output terminal and 7 are the input terminals.

The CPU 1 controls the overall operation of the device according to the present invention. Operation key 2 switches the operational mode!
However, there is a tool for sequentially inputting inspection procedures to be performed in any order. The display 3 displays the contents of the inspection procedure, the inspection results, and the like. The first mail 4 is
It stores procedure programs created in advance for each inspection content. The second register 5 is for sequentially storing inspection procedures performed in arbitrary steps. The output terminal 6 is
This is a terminal for sending a test signal to the test target. Input terminal A is a terminal into which an output signal sent from the object to be inspected is input in response to an inspection signal.

The operation of the device configured in this way will be explained.

A normal inspection is performed according to a predetermined procedure program created in advance for each inspection content stored in the first memory 4. During the actual inspection, the readout inspection procedure and the inspection results are sequentially displayed on the display 3, so that the operator can know the location of the failure from the display on the display 3. When the procedure program stored in the first memory 4 is executed and no failure is found, the operation mode is switched and the operator uses the operation keys 2 and the display 3 to
Perform the inspection using any procedure that follows. In other words, the worker
While judging the inspection results according to the specified IC procedure, the inspection is executed according to an arbitrary procedure until a failure is found. Here, these series of arbitrary procedures are stored in the memory 5 of 2 depending on luck. Then, when a failure is found, a series of inspection procedures that have been sequentially stored in the second memory 5 up to that point are added to the predetermined inspection content program in the first memory 4 as a procedure programmer and stored. As a result, from the next time onwards, the same fault can be easily found by enlarging (j'ti) a predetermined series of procedure programs including this newly added procedure program.

According to such a configuration, it is possible to significantly reduce the conventional inspection work while looking at a circuit diagram, and it is possible to improve work efficiency. Additionally, inspection work can be learned in a relatively short period of time.

In addition, in the above embodiment, an example was shown in which the first memory 4 and the second memory 5 were made independent, but they do not need to be physically independent, and it is possible to use a common memory separately. You can also do this.

As described above, according to the present invention, it is possible to realize an inspection device with a relatively simple configuration, excellent workability, and effective for finding faults in circuits of electronic devices, and has great practical effects.
