Abstract

An abnormality detecting system includes equipment for detecting an abnormality which occurs therein and for transmitting an abnormal signal, and an abnormal signal processing unit for analyzing the abnormal signal received from the electric equipment. The abnormal signal processing unit is formed in a portable shape, and receives an abnormal signal from the electric equipment in a non-contact manner by means of radiowaves or infrared rays. The abnormal signal processing unit stores beforehand data relating to abnormalities and data corresponding to the received abnormal signal can be extracted and displayed. Further, the abnormal signal processing unit can transmit the received abnormal signal to an external component by means of radiowaves or infrared rays.

Claims

1. An abnormality detecting system comprising:

electric equipment, said electric equipment including means for detecting an abnormality therein, and transmitting an abnormal signal indicative of the abnormality;

a display panel coupled to the electric equipment for receiving the abnormal signal and indicating that the abnormality occurred; and

an abnormal signal processing unit separate from the electric equipment for receiving and analyzing the abnormal signal, said abnormal signal processing unit including;

a signal receiving section for receiving said abnormal signal;

a memory section for storing predetermined data corresponding to abnormalities in said electric equipment;

a judging section coupled to said signal receiving section and said memory section for extracting data corresponding to the abnormal signal from among the predetermined data stored in said memory section;

a display section coupled to said judging section for displaying the data extracted by said judging section;

a manipulating section for inputting instructions to be carried out in said abnormal signal processing unit; and

a processing section coupled to said manipulating section for carrying out the instructions from said manipulating section.

2. An abnormality detecting system as set forth in claim 1, wherein said abnormal signal processing unit includes an additional memory section coupled to said signal receiving section for storing the abnormal signal, and a signal transmitting section for transmitting the abnormal signal stored in said additional memory section to an external device.

3. An abnormality detecting system as set forth in claim 1, wherein said abnormal signal processing unit is formed in a shape which is portable.

4. An abnormality detecting system as set forth in claim 1, wherein said signal receiving section receives the abnormal signal by one of radiowaves and infrared rays.

5. An abnormality detecting system as set forth in claim 2, wherein said electric equipment transmits the abnormal signal by one of radiowaves and infrared rays.

6. An abnormality detecting system as set forth in claim 1, wherein said abnormal signal successively indicates a plurality of abnormalities which occur in said electric equipment, at predetermined intervals.

7. An abnormal signal processing unit for analyzing an abnormal signal transmitted from electric equipment separate from said abnormal signal processing unit, the abnormal signal being indicative of the occurrence of an abnormality detected in the electric equipment, said abnormal signal processing unit comprising:

a signal receiving section for receiving the abnormal signal;

a memory section for storing predetermined data corresponding to abnormal signals received by said signal receiving section;

a judging section coupled to said signal receiving section and said memory section for extracting data corresponding to the abnormal signal from among the predetermined data stored in said memory section;

a displaying section coupled to the judging section for displaying thereon the data extracted by said judging section;

a manipulating section for inputting instructions for said abnormal signal processing unit; and

a processing section coupled to said manipulating section for carrying out instructions from said manipulating section.

8. An abnormal signal processing unit as set forth in claim 7, further comprising an additional memory section coupled to said signal receiving section for storing the abnormal signal, and a signal transmitting section for transmitting the abnormal signal stored in said additional memory section to an external device.

9. An abnormal signal processing unit as set forth in claim 7, wherein said abnormal signal processing unit is formed in a shape which is portable.

10. An abnormal signal processing unit as set forth in claim 7, wherein said signal receiving section receives the abnormal signal by one of radiowaves and infrared rays in a non-contact manner.

11. An abnormal signal processing unit as set forth in claim 8, wherein the electric equipment transmits the abnormal signal by one of radiowaves and infrared rays in a non-contact manner.
