Although the electromagnetic induction wireless power supply technology is relatively mature, but this power supply technology will be subject to many limitations, the biggest problem is that the low-frequency magnetic field will decay rapidly with the increase of distance, if the actual application to increase the power supply distance, only according to the need to increase the magnetic field strength, but the increase of magnetic field strength not only increases the consumption of electric energy, It will also cause the failure of close-range magnetic signal recording equipment, such as the magnetic strip on the bank card will be demagnetized under a strong magnetic field.
When someone called Edison a genius, he explained that "genius is one percent of the spirit.Feeling plus ninety-nine percent sweat." He in the "invention factory", many different professional people organized, there are scientists, engineers, technicians, workers a total of more than 100 people, many of Edison's major inventions are relying on this collective strength to achieve success. He said to Edison very sincerely, "I have nothing to thank you for. I hear you are interested in telegrams, and if you like, I can teach you how to send and receive them, and make you a telegrapher." These words are said in the heart of young Edison. He gladly accepted McKenzie's offer and learned to send and receive telegrams with himThe system transplantation of hardware, even in the same brand, the same series of products, also needs to be modified according to the changes and additions of the system hardware. At the same time, for different tasks, it is often necessary to make large changes to the system, and the compilation and download of the program should be combined with the system.
The main features are: the system kernel is small. Embedded systems are generally used in small electronic devices, resources are relatively limited, so the kernel is smaller than the traditional operating system. Strong specificity. The personalization of embedded system is strong, the combination of software system and hardware is close, and the general hardware system should be transplanted, even if it is the same productThe brand and the same series of products also need to be modified according to the changes and additions of the system hardware.
Embedded operating system runs in the intelligent chip environment, its characteristics are: miniaturization, customization, real-time, reliability, easy portability.
"The battery car regulator really works. The voltage regulator is mainly to stabilize the voltage in the future, so that the electricity supply of the electric vehicle is within the safe voltage range. If the electric vehicle does not have a regulator, it will accelerate the aging of the equipment, affect the service life and evenBurned parts, so that the owner is faced with the need to repair the trouble or need to update the equipment in the short term, waste resources; In serious cases, security accidents even occur, causing immeasurable losses.
The battery car regulator is mainly the future stable voltage, so it is very useful. The voltage regulator is a device that makes the output voltage stable. The regulator is composed of voltage regulating circuit, control circuit and servo motor. When the input voltage or load changes, the control circuit samples, compares, amplifies, and then drives the servo motor to rotate, so that the position of the regulator carbon brush changes, and the coil turn ratio is automatically adjusted to maintain the stability of the output voltageAgreed.
is useful. According to the query of the Pacific automobile network, the battery car regulator can ensure the accuracy of the voltage when the electric vehicle voltage rises or falls sharply, so the battery car regulator is useful.
Battery car voltage regulator is really useful when the battery car is not started, the battery power supply is powered by the battery, because it has a power reserve, without the regulator can also ensure that the power supply is relatively stable only when starting, there is a severe voltage drop, the voltage drop amplitude can reach 2~3V, and the discharge current of the battery can reach hundreds of amPs in this case, stable.
