Abstract

PURPOSE:To automatically inspect an attached microcomputer, and to prevent its attachment error by providing a display output means for outputting an article number of this microcomputer from the microcomputer having a control means for controlling an apparatus. CONSTITUTION:A control part 1, a display output means 2 and a timer means 5 are contained in a microcomputer 6. When a power source is turned on to a product by turning on an inspection switch of an inspecting device, the display output means 2 outputs article number data of the microcomputer 6 to a display device 3 by an instruction of the control part 1. The article number of the microcomputer 6 is displayed on the display device 3, and the microcomputer 6 can be discriminated. When a prescribed time elapses, it is informed from the timer means 5 to the control part 1 that a prescribed time elapses. The control part 1 instructs the display output means to output the present control state, or RAM data of the microcomputer 6 to the display device 3. The display output means 2 stops the output of the article number data, and outputs instructed information to the display device 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microcomputer part number discriminating device for confirming the part number of a microcomputer when a microcomputer for controlling product equipment is attached.

[0002]

2. Description of the Related Art Conventionally, in the inspection of a finished product of a control device for controlling a product, only the inspection regarding the specification of the control device is performed. When a product control device is shared and different products (for example, products having the same specifications other than the hot water supply capacity of the product but different only the hot water supply capacity) are developed, it is necessary to change the microcomputer of the control device with the capacity control circuit. there were. In this case, the product had the same specifications except for the hot water supply capacity, so the inspection items were shared.

[0003]

However, according to the above-described inspection method, since the inspection items are shared, the microcomputers cannot be distinguished, and the inspection items are shared even if different microcomputers are incorporated in the product control device. Because of this, it could not be detected, and the wrong attachment of the microcomputer occurred.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to automatically inspect the attached microcomputer and prevent the attachment error.

[0005]

In order to achieve the above object, the first means of the present invention comprises display output means for outputting the product number of this microcomputer from a microcomputer having a control means for controlling the equipment. It is a thing.

The second means is provided with a timer means for outputting the product number of the microcomputer for a fixed time.

[0007]

[Operation] By outputting the product number of the microcomputer, the product number of the microcomputer is automatically inspected to prevent mistakes in the attachment of the microcomputer.

Further, by outputting the microcomputer part number only for a fixed time, the output port of the microcomputer is used for another purpose after the lapse of the fixed time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the microcomputer product number discriminating apparatus of the present invention will be described below with reference to FIG.

In FIG. 1, a control unit 1 controls the entire product. The display output means 2 is means for outputting the product number of the microcomputer according to an instruction from the control unit 1. The display device 3 is a device for displaying the data output from the display output means 2.

The control device 1 controls the product and
The display output means 2 is instructed to output the product number of the microcomputer. Upon receiving an instruction from the control unit 1, the display output means 2 outputs the product number data of the microcomputer to the display device 3 in ASCII code, and the display device 3 displays the received product number of the microcomputer. The control unit 1 and the display output unit 2 are contained in a microcomputer (hereinafter, also referred to as a microcomputer) 4.

By connecting an inspection device (not shown) capable of confirming the product number of the microcomputer to the display device 3, the product number of the microcomputer output from the display output means 2 can be read by the inspection device. It is possible to identify, and it is possible to automatically prevent a mistake in attaching the microcomputer 4.

Next, another embodiment of the present invention will be described with reference to FIG. In FIG. 2, the display output means 2 in the above-described embodiment is provided with the timer means 5. The timer means 5 and the like are housed in the microcomputer 6 shown by the broken line in the figure.

After the inspection switch of the inspection device is turned on to turn on the power to the product, the product number of the microcomputer is output from the display output means 2 to the display device 3 according to the instruction of the control unit 1 until a predetermined time elapses. You can

When a certain time has elapsed, the timer means 5 notifies the control unit 1 that the certain time has elapsed. Control unit 1
Then, the display output means 2 is instructed to output the current control state or the RAM data of the microcomputer 6 to the display device 3. The display output means 2 stops the output of the product number of the microcomputer and outputs the current control state or the RAM data of the microcomputer 6 to the display device 3. By providing the timer means 5 in this way, the output port of the microcomputer 6 can be effectively used.

[0016]

As described above, according to claim 1 of the microcomputer product number discriminating apparatus of the present invention, the type of the microcomputer can be discriminated even when the control device is incorporated in the product.
It is possible to prevent the wrong attachment of the microcomputer.

According to the second aspect of the present invention, the microcomputer is provided with the timer means, and the output port of the microcomputer can be used for other purposes besides outputting the microcomputer part number.
