JPH0363896A - Detecting device for working time of equipment or the like - Google Patents

Abstract

PURPOSE:To form a device small in size and to solve the problem of pricing for use for most equipment or the like by separating the device to a detecting part and a display part, and mounting only the detecting part on the equipment. CONSTITUTION:When the equipment 1 is operated, an electrical signal is inputted to an operation detection circuit 4, and it is processed at a clock circuit 5, and is stored in an operating time memory circuit 6, and since the power source 1a of the equipment is disconnected when the operation of the equipment is stopped, a power source switching circuit 3 is operated so as not to dissipate data. When working time is detected, a reader is connected to an external output circuit part, and the working time is displayed on the display part provided at the reader. In such a way, an inexpensive and accurate detecting method for the working time of the equipment can be obtained.

Description

Detailed Description of the Invention (a> Industrial Application Fields The present invention relates to IIi appliances such as electrical products and electronic #IA devices, their structures Ifi, devices for detecting the usage time of B products, and 1. It is related to the system.

(b) Purpose of the Invention In recent years, the reliability of electric products such as ε1 electronic machines has significantly improved and the product life has been significantly extended, but failures still occur and there are dangers such as fire. In some cases, accidents have occurred where products have to be recalled. There are various causes of such accidents, such as the performance of the equipment and its components, and how the equipment is handled, but regardless of the cause, one of the things you want to know when an accident occurs is the amount of time the equipment was used, and how long the equipment was used. It is common practice to take countermeasures by investigating the time and cause of the accident, but since it is usually impossible to accurately determine the usage time, the present invention is based on the serial number of the equipment. The purpose of this invention is to provide a method and device for accurately determining the usage time of equipment and its component parts.

(c) Conventional technology electrical equipment and electronics 8! One possible method for detecting the usage time of equipment such as appliances and their component parts is to have a timer or usage time recording device built into the body, but this is very expensive and requires special equipment. It is difficult to use it for anything other than electronic equipment, and there is no known inexpensive and effective method for detecting usage time that can be used for various home appliances and many type R5 machines.Under these circumstances, the present inventors is patent application 63-33
In 2620, he invented a method that utilizes the color difference in a colored layer that changes color when irradiated by a light source such as an ultraviolet lamp or LED placed on a printed circuit board in conjunction with the machine ml. Variations are inevitable, and it is not possible to accurately detect the usage time as with a built-in timer.

In other words, there is a demand for an inexpensive and accurate method for detecting usage time, but at present no method has been found that completely satisfies the general public. As mentioned above, a method for accurately detecting the usage time of component parts is to link a timer using IC or the like with the equipment, but the condition of inexpensive supply is satisfied as long as off-the-shelf parts are used. Can not.

However, as is obvious from looking at calculators and watches, the price of electronic components decreases as they are used over a wide range of areas, so if we create a universally usable @Category 5 usage time detection device, the price issue will be resolved. It is possible. In other words, we have developed integrated circuits that include active elements for processing electrical signals from tags, storage elements for storing information, etc., and we have developed integrated circuits that include active elements for processing electrical signals from tags, storage elements for storing information, etc. A backup power source that automatically switches from the mains, information! The goal is to develop a device that detects the usage time of equipment and includes a connector for connecting to a reading device. As a result of intensive research based on this concept, we were able to obtain a #Ran usage time detection device that is inexpensive, accurate, and universal. The usage time detection device was created by mounting the above-mentioned IC, backup power supply, connector, etc. on a special printed circuit board. Of course, it may be mounted directly on the S class, or it may be an IC card system.

This will be explained below using examples.

〔Example〕

FIG. 1 is a block diagram schematically showing a method for detecting the usage time of machines S, and 2 inside the broken line is a usage time detection device. In this figure, 1a is a power supply for operating the device, 3 is a power supply switching circuit section, 4 is an operation detection circuit section, 5 is a clock circuit section, 6 is an operating time storage circuit section, 7 is an external output circuit section, and 8 is a CPU SRO.
It is MB.

The operating time detection system for the equipment includes: when the V & R is operated, an electrical signal is input to the operation detection circuit 4, processed at clock times I2 & 5, and stored in the operation time storage circuit 6;
When the operation of the equipment is stopped, the power of the ta equipment is turned off! ! 1a is stopped, the power switching circuit 11S3 is configured to operate so that the data is not lost.When detecting the usage time, a reading device is connected to the external output circuit section, and a reading device is installed in the reading device. The usage time is shown on the display section.

To put it simply, this detection system connects a reading device to the external output circuit of the detection device 2 to check the usage time of the TA device when inspecting the equipment or when there is a malfunction. It has the following characteristics and is excellent in universality, so it can be used in many wABs.

The usage time detection device is installed in home appliances such as electric fans, refrigerators, and washing machines, as well as radio equipment, machine tools, and 41 testing machines, and after the equipment has been operated for a predetermined period of time, a reading device is connected to check the operating time. As a result, very accurate results were obtained, and it was found that the system could be used satisfactorily as a system for detecting the usage time of equipment. This system uses electrical signals and power supply from the equipment, but if the power supply is synchronous with the electrical signal, only 14 sources are needed, and since it has a backup power supply, , tsr:LIm can also be used to measure the elapsed time from immediately after the manufacture of 81!5.

(e) Effect of the invention The feature of the usage time detection system for vJ equipment is that, as mentioned above, the detection part and the display part are separated and only the detection part is attached to the equipment, making it possible to create a very small device. In addition, since the device can be used in most types of equipment, mass production of the device has become possible, and the problem of price can be solved.

Furthermore, since the detection system is a method that actually measures the operating time of MSs, another great effect of the present invention is that it is possible to determine the operating time of the equipment very accurately. Since it is very useful for measuring the reliability of equipment, or its component parts, it can be said that it is important from the perspective of quality assurance.
