Description

A combination of devices for increasing the transmission distance of radio frequency identification signals

technical field

The invention relates to a combination of devices for increasing the transmission distance of radio frequency identification signals, in particular to a combination of devices for increasing the transmission distance of radio frequency identification signals by increasing power.

Background technique

In recent years, the research field related to Radio Frequency Identification (RFID) has developed quite rapidly, and related products using RFID have gradually occupied a place in the market. The so-called RFID technology, in short, is a non-contact automatic identification technology composed of tags and readers.

Generally speaking, the main working principle of RFID technology is to place or embed a very small RFID tag chip in the product, and the product data stored in the RFID tag chip can be sent to the RFID tag reader through a radio frequency signal for tracking for. Since RFID technology does not require manual operation when performing identification work, RFID technology can be applied to toll collection systems (such as traffic cards) and identification (such as access control cards).

For example, RFID technology is applied to the charging system (such as traffic card), that is, the user needs to touch the traffic to the host, and when the host makes a sound to remind the user that the card is swiped successfully, it is convenient for the user to travel; in addition, RFID is used for identification ( Such as access control card), that is, the user needs to touch the access control card to the host end, and when the host end makes a sound to remind the user that the identification is successful, so as to increase security.

However, considering that the distance of the RFID signal returned by the general transportation card or access control card itself is relatively small, it needs to touch the host to swipe the card effectively, and the sensitivity of the host must be strong enough, otherwise the user may need to repeatedly swipe the card, bringing users a lot of trouble. Therefore, in view of the fact that conventional signal transmission devices lack the ability to effectively increase the transmission distance of radio frequency identification signals, the inventor feels that there is a need for improvement, and has actively worked on it based on his many years of creative design and professional manufacturing experience in related fields. Research and improvement on a device combination that uses wireless technology to effectively increase the transmission distance of radio frequency identification signals, and finally develop the present invention after careful consideration of various conditions.

detailed description

This specification mainly provides a device and its combination for increasing the transmission distance of radio frequency identification signals. The device receives surrounding high-power wireless signals through a wireless charging terminal and stores them in a power storage unit. A radio frequency identification signal can have more sufficient power for signal feedback, so as to effectively increase the transmission distance of signal feedback.

Hereinafter, the characteristics and functions of the present invention will be described in detail in conjunction with a preferred embodiment shown in the reference drawings; please refer to FIG. 1 , which is a system architecture diagram of the present invention. The invention is a combination of devices for improving the transmission distance of radio frequency identification signals, including a client terminal and a host terminal. The client includes: a radio frequency identification signal receiving unit for sending and receiving radio frequency identification signals; a wireless charging terminal for receiving wireless signals, and the wireless signals include high-power wireless signals; a power storage unit for receiving the wireless signals And the power transmitted by the radio frequency identification signal, and charging and power transmission; a first calculation unit is used to store data; it is characterized in that the wireless charging receiving end can provide the power carried by the wireless signal received The power storage unit is used for power storage.

Please refer to FIG. 1 and FIG. 2 . FIG. 2 is a flow chart of the application of the present invention. The host includes: a wireless charging transmitter for sending high-power wireless signals; a radio frequency identification signal reading module for sending and receiving radio frequency identification signals; a setting unit for setting the client as a default client terminal; and a second calculation unit; it is characterized in that: the host terminal sends a radio frequency identification signal to the client through the radio frequency identification signal reading module and receives the radio frequency identification signal fed back by the client, the The second computing unit judges whether the client is the default client set by the setting unit, and if so, the wireless charging transmitting end of the host sends the high-power wireless signal to the client , the wireless charging receiving end of the client receives the high-power wireless signal and provides the power carried by the high-power wireless signal to the power storage unit for power storage, and the power stored in the power storage unit When the power is available for the radio frequency identification signal receiving unit to receive the radio frequency identification signal, there is more power to feed back the data stored in the first computing unit to the host; if the second computing unit judges that the client If the client is not the default client set by the setting unit, the host does not send the high-power wireless signal.
