Electronic device and peripheral device matching system and its matching method

Abstract

The invention discloses a matching system for an electronic device and a peripheral device and a matching method thereof. The system comprises an electronic device and a peripheral device, wherein, the electronic device is provided with an identification mechanism used for indentifying a specific identification code and producing a control signal or a control instruction according to an identification result; the peripheral device is electrically coupled with the electronic device selectively and comprises an identification code unit, in which a group identification code is stored, and a power control unit, which controls the operating state of the peripheral device according to the control signal or the control instruction when the peripheral device is electrically coupled with the electronic device. When the identification result is that the specific identification code is consistent with the group identification code, the power control unit ensures the normal operation of the peripheral device according to the control signal or the control instruction. Therefore, only two signal lines are required to finish the task, thus ensuring a certain uniqueness of the product and less manufacturing cost of the whole identification circuit, and further increasing the competitiveness of the product.

Description

technical field [0001] The present invention relates to a device matching system and a matching method thereof, in particular to a matching system and a matching method of an electronic device and a peripheral device. Background technique [0002] Under the trend of thin, light and small design, the volume of notebook computer is getting smaller and smaller, but under the limitation of the size of some mechanical parts, the volume of notebook computer is still limited. Therefore, in order to reduce the volume of notebook computer and take into account the desktop The computer has the same function, so a peripheral device has been developed, such as a docking station. The docking station is composed of connection ports of various interface specifications, such as Universal Serial Bus (Universal Serial Bus, USB), PS / 2 port, IEEE1394, parallel port (parallel port), serial port (serial port), Ethernet port (RJ-45) and CD-ROM, etc., through the design of separating the expansion ...

[0002] Under the trend of thin, light and small design, the volume of notebook computer is getting smaller and smaller, but under the limitation of the size of some mechanical parts, the volume of notebook computer is still limited. Therefore, in order to reduce the volume of notebook computer and take into account the desktop The computer has the same function, so a peripheral device has been developed, such as a docking station. The docking station is composed of connection ports of various interface specifications, such as Universal Serial Bus (Universal Serial Bus, USB), PS / 2 port, IEEE1394, parallel port (parallel port), serial port (serial port), Ethernet port (RJ-45) and CD-ROM, etc., through the design of separating the expansion seat from the notebook computer, the notebook computer can be greatly reduced. The weight of the computer and the reduction of its volume, if the user needs to connect with the peripheral device, as long as the notebook computer is installed on the expansion stand, the data transmission operation with the peripheral device or the charging operation of the notebook computer can be carried out, but due to the expansion After the socket is released, it is easy for competing manufacturers to obtain it. Therefore, manufacturers often affect the market share of notebook computers and expansion sockets through product appeals of compatibility. Therefore, a circuit design is needed to increase competitors' appeals for compatible products. Difficulty in seizing the market, in order to ensure that their own products can maintain a certain degree of uniqueness, and thus have a better product competitive advantage
