Wireless control system and wireless control method for realizing device power supply on-off operation

Abstract

The present invention relates to a wireless control system and a wireless control method for realizing the power supply on-off operation of equipment. The wireless control system includes a wireless switch device and a wireless remote control device, the wireless switch device is used to be arranged between a power supply and a device in a passive standby state when not powered, and includes a transceiver antenna, an ambient energy collection and storage unit, Power supply judgment and selection module, passive wake-up module, control module and controlled module. The passive wake-up module is connected to the transceiver antenna and converts the received wireless energy signal into a pulse signal, so that the control module is powered and outputs the control signal , so as to prompt the controlled module to perform the on-off operation between the device and the power supply, the wireless remote control device is matched with the wireless switch device and includes a sending and receiving antenna and a remote control control module. By adopting the invention, the standby power consumption of various types of equipment can be completely eliminated, so it has great application value and is suitable for widespread promotion.

Description

technical field [0001] The present invention relates to the technical field of switch control, and in particular, to a wireless control system and a wireless control method for realizing the power supply on-off operation of a device. Background technique [0002] With the increasing global warming, energy conservation and emission reduction have become the top priority of governments in various countries, especially the electrical and electronic industries that are closely related to daily life and production. Efficiency and low power consumption have become one of the important factors that must be considered in the research and development process of electronic products, which are more competitive in the market. [0003] The standby power consumption of various electronic devices has become one of the important issues to be solved in energy conservation and emission reduction. However, there are still some problems and drawbacks in the use of many devices such as televisio...

Problems solved by technology

[0004] In order to solve the problem of standby power consumption, although various zero-power standby schemes have appeared, there are still many problems in these schemes, which need to be further improved and perfected.

For example, because the control signal of the existing wireless switch remote control device needs to cover a certain range to achieve operational convenience, precise directional transmission cannot be used, and the wireless energy transmission, reception and conversion process itself has relatively large losses, making wireless energy transmission efficient. Not too high, the final energy absorbed and utilized by the wireless switch device is very low, and most of the energy is radiated into the air and wasted

Another example is that the existing wireless switch remote control device needs to consume a large amount of wireless energy. Even if a high-priced, large-capacity battery is used for power supply at the remote control end, its working life will be greatly limited, and the cost will be increased.

For another example, if considering the need to ensure that the remote control signal of the wireless switch device can cover a certain range, especially hoping to achieve accurate directional transmission, then a higher requirement is proposed for the wireless switch remote control device (especially the two parts of the power amplifier and the transmitting antenna) requirements, and the existing ordinary power amplifiers and on-board patch antennas are difficult to meet the requirements, so if this kind of wireless switch device is to be used, it is necessary to increase the volume of the remote control terminal, which will bring many problems to daily applications and manufacturing costs.
