Subsequently, the diagnostic control circuit 42 sequentially executes diagnosis from the processing circuit 412 (not shown) to the processing circuit 41n.

[Problem to be solved by the invention]

As mentioned above, in the conventional diagnostic result display method, when the diagnostic control circuit detects a defect as a result of diagnosis, it sends a defect detection notification, and the processing circuit that receives the defect detection notification causes the light emitting means to emit light to identify the defect. Since the system is configured to display a display, maintenance personnel can confirm the occurrence of a defect using the light-emitting display, but there is a maintenance problem in that the nature of the defect is unknown and all preparations for investigation and repair must be made.

SUMMARY OF THE INVENTION An object of the present invention is to provide a diagnostic result display method that solves the above-mentioned problems by classifying defect contents into predetermined types and notifying the processing circuit from the diagnostic control circuit.

[Means to solve the problem]

In the diagnosis result display method according to the present invention, when a diagnostic control circuit coupled to a plurality of processing circuits and diagnosing each processing circuit detects a defect, the processing circuit in which the defect has been detected displays the occurrence of the defect using a light emitting means. In the diagnostic result display method, the diagnostic control circuit sends the type of defect to the processing circuit in which the defect has occurred, and the receiving processing circuit identifies the type of defect and sets the light emission of the light emitting means to a predetermined state.

[Actual travel example]

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a functional block diagram showing one embodiment of the present invention;
FIG. 1 is a flowchart showing an example of the main operating procedure of the diagnostic control circuit shown in FIG.

In FIG. 1, processing circuits 11 to ln are connected to a diagnostic control circuit 2 via a control bus 3. In FIG. Each of the processing circuits 11 to 1n includes a functional processing section 15. Information transmitting/receiving section 12. It has a defect type identification section 13 and a light emitting display section 14. The diagnostic control circuit 2 also includes a diagnostic information generating section 2.
1. Information transmitting/receiving section 22. Failure diagnosis section 23. Defective content memory 24. and a defect type notification section 25.

The function processing unit 15 receives information/data from the control bus 3 via the information transmitting/receiving unit 12, and transmits the information/data that has been functionally processed according to a predetermined program/data to the information transmitting/receiving unit 1.
2 to the control bus 3.

The defect type identifying section 13 examines the incoming call information sent from the diagnostic control circuit 2, identifies the defect type, and transmits a light emission instruction set in advance for each identified defect type to the light emission display section 14.

The light-emitting display section 14 has a light-emitting diode, and blinks the light-emitting diode according to the light-emitting instruction received from the defect type identification section 13.

The diagnostic information generating section 21 generates diagnostic information for diagnosing each of the processing circuits 11 to 1n during diagnosis execution, and transmits it to the control bus 3 via the information transmitting/receiving section 22. The diagnostic information is sent to the processing circuit 11 for diagnosis, and when the diagnosis is completed, it is sequentially designated and moved to the processing circuit ]n.

The defect diagnosis section 23 receives processing information returned from the processing circuit to which the diagnostic information is transmitted from the control bus 3 via the information transmitting/receiving section 22, and diagnoses the presence or absence of a defect. The defect content detected by the defect diagnosis section 23 is stored in the defect content memory 24, while the predetermined defect type is sent to the defect type notification section 25.

The defective contents memory 24 allows the stored contents to be read by exhalation pressure means (not shown).

When the failure type notification unit 25 receives notification of the failure type from the failure diagnosis unit 23, it transmits information on the failure type to the processing circuit that has sent the processing information via the information transmitting/receiving unit 22 and the control bus 3.

Next, the operating procedure will be explained. As shown in Figure 2,
First, the diagnostic information generating section 21 transmits diagnostic information to the processing circuit 11 (Sl). In the processing circuit 11, the function processing section 11 receives diagnostic information, performs functional processing, and transmits the result as processing information, so the defect diagnosis section 23 receives this processing information (S
2) Do. The defect diagnosis unit 23 diagnoses the defective matter from the received processing information (S3)L, and after detecting the defective content (S4), records the defective content in the defective content memory 24 (S5).
At the same time, it is classified into a predetermined defect type and notified to the defect type notification section 25 as defect type information, and the defect type notification section 25 further transmits the defect type information to the processing circuit 11 that is the processing information source (S6). and the procedure ends. The defect type information is identified by the defect type identification section 13 from the information received via the control bus 3, and the light emitting diode of the light emitting display section 14 is made to blink according to the preset light emission type.

FIG. 4 is a time chart showing an example of the blinking state of the light emitting display section of FIG. 1. FIG. In Figure 4, call cannot be detected (A),
Blinking is shown for three failure types: voice failure (B), call failure (C). Voice disconnection (B) and call failure (
In each of C), the lighting time width is the same and the lighting period is half and double, respectively, as compared to the blinking state of call detection undetectable (A). In this way, it is possible to change only the lighting time width instead of the period, or to combine changes in both the lighting time width and the period, or any other method as long as it is periodic.

According to the above embodiment, the light emitting body of the light emitting display section is a light emitting diode, but any illumination device such as a lamp may be used as long as it can control blinking. Although it has been explained that the diagnosis is carried out sequentially from the processing circuit 11 to the processing circuit 1n, the order may be arbitrary. The defect content recorded in the defect content memory and the defect type transmitted/received may be the same, or the recorded content may be detailed.

Some of the functional blocks shown in FIG. 1 illustrate, for example, functions that a microprocessor performs by making full use of programs and data stored in a storage device, and the flowchart shown in FIG. The above description does not limit the present invention, as S6 may be interchanged.

As explained above, according to the diagnostic result display method of the present invention, the diagnostic control circuit detects the type of defect and transmits it to the processing circuit, and the processing circuit is configured to blink the light-emitting display according to the received defect type. As a result, the cause of the defect in the defective processing circuit can be distinguished, and preparation and execution of investigation and repair can be carried out quickly, and it is also possible to determine whether emergency measures are required before starting.
