Automobile alarm and safety
Generally, cars are equipped with car alarms, which are alarm devices installed on cars. If someone hits, impacts, or moves the car, the sensor will send a signal to the controller indicating the vibration intensity. According to the intensity of vibration, the controller will give out a warning sound or sound an alarm completely. In order to deter the thief, and prompt to inform the owner.
The most basic automobile alarm system generally consists of one or more sensors and alarms connected with them. The simplest alarm system is to install a switch on the driver's door and connect the circuit. If someone opens the door, the alarm will sound. Installing this kind of automobile alarm system requires a switch, several wires and an alarm. The alarm system of most cars is much more complicated than this. These alarm systems generally include: a group of sensors, including switches, pressure sensors, motion detectors and alarms that can make a variety of sounds, from which you can select a different sound. The radio receiver and standby battery wirelessly controlled by the key card can also ensure the normal operation of the alarm system when the main battery is disconnected. The computer control unit, which is also the "brain" of the alarm system, can monitor the surrounding situation and give an alarm. The "brain" of many advanced alarm systems is actually a small computer. When the sensor senses an abnormal situation, the "brain" closes the switch and activates the alarm device (i.e., horn, headlight or alarm). Different security systems use different sensors, and the sensors are connected to the controller in different ways. The controller and alarm system are generally connected with the main battery of the car, and are usually equipped with standby power supply. If someone cuts off the main power supply (such as cutting the battery cable), this hidden standby power supply will intervene in the power supply.
When the power supply is cut off, it is very likely that someone is stealing a car, at which time the controller will start and sound an alarm.
In addition to car alarms, the car HUD display also greatly improves safety during driving. HUD means head-up display, which was used as a flight aid in aircraft in the early days, and then was used in automobiles. To put it simply, the driver can reduce the frequency of looking down at the instrument, which will avoid the driver's attention interruption and reduce the probability of accidents. The principle of HUD is to use the principle of optical reflection to project important driving data onto the front glass, which includes two structures: data processing and image display. This configuration is widely used in high-end cars, and some middle and low-end cars are not matched, but it can be realized through later modification.
There are many kinds of pressure sensors inside the automobile. When the pressure alarm lamp on the dashboard lights up, it is necessary to pay attention to the condition of the automobile. If the engine oil pressure warning lamp is on, it means that the engine lubrication system may have failed, and the engine oil pressure is insufficient. Common reasons include insufficient oil pump pressure, blockage of oil pump filter screen, blockage of engine oil passage, too low oil viscosity, too low oil quantity and failure of an oil pressure sensor, etc. Once the engine oil alarm light comes on, you need to stop and turn off the engine immediately. Get off and check whether the engine oil is enough. If it is not enough, there is no leakage. If there is no leakage, you can continue driving by adding engine oil. If there is no shortage of engine oil, it is possible that the pressure of the oil pump is insufficient or the oil passage is blocked, which requires professional maintenance personnel to rescue. The tire pressure warning light is on, indicating excessive tire pressure. The pressure is too high, and it is easy to puncture, so it is necessary to depressurize the tire. In addition, insufficient pressure will increase fuel consumption, so it is necessary to confirm the reasons that affect the pressure.
