Problems solved by technology

However, this device cannot tell whether it is the original buckle or the small plug-in bought by the car owner. Some merchants just saw this loophole and produced the small plug-in, regardless of the safety of the driver, for profit.

Abstract

The invention discloses a substitution-prevention safety belt which comprises a safety belt, and a secondary buckle and a primary buckle arranged at ends of the safety belt. A Hall sensor is mounted on the primary buckle and is connected with a processing circuit, the processing circuit is connected with an MCU (micro controller unit), the MCU is connected with an ignition controller, the secondary buckle and the primary buckle are arranged in pairs, and the MCU only identifies the secondary buckle in pairing. By the aid of the substitution-prevention safety belt, the secondary buckle can be prevented from being substituted by a small plug-in, a driver has to wear the safety belt, safety of the driver is protected, and damage of accidents is lightened. The invention further discloses a substitution-prevention method of the safety belt. The method includes that the secondary buckle in pairing is inserted into the primary buckle, the Hall sensor produces voltage, the MCU sends an enable signal to the ignition controller after identification, and then the ignition controller is permitted to start an engine; when a mismatching secondary buckle is inserted into the primary buckle, the Hall sensor produces another voltage, the MCU identifies and determines the voltage to be ineffective, and then the ignition controller is prohibited from starting the engine.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an automotive safety belt. Background technique [0002] With the increasingly developed urban traffic and the increasingly congested roads, many car owners are more and more inclined to drive without wearing seat belts in short-distance journeys. For them, the main reason is, "It takes less than two or three kilometers to drive, so there is no need to tie it", "Anyway, the road is congested, so it's okay to drive slowly", "It's too troublesome, and it's uncomfortable to tie it on", etc. . And the existing alarm system is: before the driver will start the engine, if the seat belt buckle is not inserted, the alarm system will work to remind the driver to fasten the seat belt. Even if the driver is not wearing a seat belt, the engine can still be started, despite the system's speed limit and air bag warning. [0003] For this reason, in order to avoid trouble, the drivers u...
