Problems solved by technology

[0002] At present, when known cars and other motorized equipment are running, their lighting and signal lamps break down randomly, and the driver is blind. Therefore, when the vehicle needs to overtake, turn or stop, the driver usually controls the corresponding signal. Lamps are used to show signs to relevant vehicles or pedestrians. However, when the signal lamps have failed, the relevant vehicles or pedestrians cannot get information and cannot perform effective rendezvous or avoidance. A lot of painful prices have been paid for this, so check the driving vehicles The quality of signal lamps is one of the main tasks and punishment items of traffic police

Embodiment Construction

[0018] 1. The precise potential identification part of the arithmetic unit.

[0019] 1. Circuit composition:

[0020] by D 2-n with R 3-n The formed voltage divider circuit obtains the voltage of DC12V-0.4V, and the potential of point B is added to the arithmetic unit A 1-n IN (--) terminal.

[0021] By vehicle control switch K 1-n , Diode D 1-n , lamps X 1-n , resistance R 1-n , Analog switch MK 1-n and its from the analog switch MK 1-n The 47K resistance connected to the positive power supply on the control pole constitutes a circuit, forming the potential voltage of point A and adding it to the arithmetic unit A 1-n IN (+) terminal.

[0022] The potential of point A is also the input voltage of the NAND gate inverter.

[0023] The potential of point A changes with the driver's operation on the lamp and whether the lamp fails or not.

[0024] 2. The working status is described as follows:

[0025] (1) Manual operation K 1-n On

[0026] A. Set lamps X 1-n good...

Abstract

The instrument for detecting and warning motor vehicle light failure is characterized by that it adopts the light circuit isolation technology, and uses double-discriminator circuit formed from accurate potential discrimination implemented by operational unit and gap potential compensation implemented by negation gate to dynamically detect out failed light and warn driver of light failure. Said invention is also applicable to detection and warning of illuminator and signal light failure of aircraft and ship, etc..

Description

Technical field [0001] The invention relates to an instrument capable of giving warnings in time when lighting and signal lamps equipped with automobiles and other motorized equipment fail. Background technique [0002] At present, when known cars and other motorized equipment are running, their lighting and signal lamps break down randomly, and the driver is blind. Therefore, when the vehicle needs to overtake, turn or stop, the driver usually controls the corresponding signal. Lamps are used to show signs to relevant vehicles or pedestrians, but when the signal lamps have failed, the relevant vehicles or pedestrians cannot get information, and cannot effectively rendezvous or avoid, which has paid a lot of painful price, so check the driving vehicles The quality of signal lamps is one of the main tasks and punishment items of traffic police. Contents of the invention [0003] In order to overcome the lack of blindness of the driver when the lighting and signal lamps of ...
