Description of the Invention (ί) (Please read the precautions on the back before filling out this page) The present invention relates to a device for judging and displaying operation errors in a car ', and in particular to A device for judging and displaying an operation error in a car, 'it can judge the operation error of electronic parts and circuits in the auto-tuning α' and analyze the judgment result 1 to accurately inform the driver of the position where the operation error occurred. During the operation of the car, when an abnormal situation occurs, in other words, when the car malfunctions, it will put safe driving at risk. Most drivers have only a little knowledge of vehicle maintenance and cannot properly overcome such abnormal conditions. For example, during a car ’s operation, when a sudden misoperation or deterioration occurs, most drivers are often confused and put safe driving at risk. In addition, they tend to forget rather than think about immediately and systematically identifying a functional error and repairing it. Even experienced drivers may spend a lot of time directly identifying and repairing dysfunction. The driver can directly address the basic car maintenance detailed in the car maintenance manual. However, when the driver is driving, when the car fails, it is not easy to refer to the manual and find out the problem. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs When a machine fails, even a driver with knowledge of car maintenance may not be able to easily spot the problem. If he / she successfully finds the problem, it is difficult to repair the problem without spare parts and tools to repair the problem. In addition, in electric faults, compared with drivers who have sufficient knowledge of car maintenance, they can easily solve the problem by checking the fuses or relays in the car. Most traditional drivers cannot handle this problem because of insufficient knowledge. In particular, when the fuse in the car's shit fuse box is burnt out, 'If this paper size applies the Chinese National Standard (CNS) A4 specification (2: h: 97 mm) 472007 5737pif.doc / 008 B7 V. Description of the invention (I) He / she has successfully found the fuse box. Most drivers have a hard time finding out which of the many fuses of various colors is burned out. Fuses are generally used to protect electronic components or electronic circuits from damage during excessive load. In a composite device such as a general automobile or industrial equipment that requires many fuses and wires, an additional fuse box is provided for integrated management of the fuses and wires. In the case of automobiles, colored fuses are used to indicate the use of each fuse in the fuse box, and a translucent fuse is used to easily indicate a faulty fuse. The average driver does not notice such a message, so it is difficult to check the power failure of the fuse by removing each fuse of the fuse box. In addition, if the space of the fuse box is small and the surroundings of the fuse box are usually dark, it is even difficult to replace the fuse in the fuse box. In addition, for a sealed part such as a relay used in an automobile, it is almost impossible for a driver to find a defective relay and remove it. When a car with such a defective fuse or relay is being driven, one or all parts of the car such as switch control panels, various light bulbs, windshield wipers, air conditioners, sound elements, igniters, defrosters, etc. You will not be able to work properly, causing inconvenience during driving or even accidents. In order to solve the above problems, an object of the present invention is to provide a device for judging and displaying an operation error in a car, which can judge and display an electronic error in the car. Another object of the present invention is to provide a device for judging and displaying an operation error in an automobile ', which can be easily connected to an appropriate position of a built-in or external type fuse box in an existing automobile.

FIG. 18 shows a power circuit diagram of an additional independent power source connected to the fuse, so that the judgment circuit of the present invention can be operated in a state where the car is not started. In Figure 18, an extra power supply circuit is connected, making the CNS A4 specification (210 × 297 mm) 472007 A7 __5737pif.doc / 008_ ΒΊ 5. The description of the invention ('〆') The judgment circuit 20 is even available. When the power switch installed on the pressurizing terminal of the fuse 10 is turned off = the power circuit has an independent power source VCC 181 and an independent ground terminal BGND 182. The grounding terminal 182 performs a floating grounding function, which is separated from the existing grounding terminal AGND 180 to prevent the reverse current of the diodes Da and Db without affecting the existing power supply and judging the voltage change across the fuse. . The judgment circuit 20 is connected to the contacts P1 and P2. Therefore, if the voltage of the main power source + 12 volts (V) is not supplied to the fuse 10, the judgment circuit 20 operates. When the car is not started, a small current will flow into the fuse 10 due to the independent fuse power supply circuit. If this current is small, the resistors Ra and Rb can be designed to ignore this current. Therefore, when the automobile is not started and the fuse is in the disconnected state, the judgment circuit 20 can know that the fuse 10 is in the disconnected state. As described above, the device for judging and displaying an operation error in a car according to the present invention can be manufactured not only as a built-in type, but also as a card type or an external box type, so that it can be easily applied to almost all Type of car. For external versions, the unit can be installed without extensive modification of existing fuse boxes. Although the present invention has been described above using the application of automobiles, the present invention can also be applied to various other places such as industrial electric wires or atomic reactors, underground equipment or narrow and narrow canals and other places where maintenance is difficult. In summary, according to the device for judging and displaying operation errors in a car according to the present invention, a driver with a small amount of car maintenance knowledge can also easily perform repair work, or learn by sound-visual method to operate in a car Wrong judgment results and emergency measurement work. In addition, using the device for judging and displaying operation errors in a car of the present invention, an automobile expert or a repair shop may apply the Chinese National Standard (CNS) A4 specification (210X297 mm) to this paper size (please read the precautions on the back before filling in (This page)
