Method and device for plug and play of function extension card in electronic information device

Abstract

The method includes the following steps: 1) inserting card into host slot; 2) judging whether the card is plug and play operating card or not, if it is, to continue with step 3). otherwise to go to step 9) directly; 3) interrupting current operation program of the host; 4) loading card function into the host; 5) operating the card function in the host; 6) drawing-out the card from the host slot; 7) holding host environment and closing the host for protection; 8) checking the host state and to restore it to safety mode and 9) restoring the host the operation mode before the card is inserted.

Description

1. Technical field [0001] The invention relates to a plug-and-play method and device for a function expansion card in electronic information equipment. 2. Background technology [0002] With the development and maturity of computer and electronic technology, electronic information devices such as personal digital assistants (PDA), MP3 (MPEG Layer3) players, notebook computers (Note Book) and electronic dictionaries can support the function of inserting cards. Rapid development and increasing popularity, therefore, each product manufacturer has invested a lot of manpower and material resources in the research and development and improvement of this type of product, hoping to launch a specification model that meets market demand, in order to meet the fierce competition and ever-changing trends Can gain a leading edge in the sales market channel. [0003] The current market demand trend and the most time-consuming research and development work of various manufacturers focus on...

Problems solved by technology

[0004] Since the above procedure needs to be completed every time the card is replaced, it is quite inconvenient for the user, and most of the electronic information devices currently on the market tend to be thinner and smaller. Convenient electronic information equipment is most favored by consumers, so electronic information equipment manufacturers have to reduce the operation panel keys of the equipment to meet the market demand for product miniaturization, so users replace these miniaturized electronic information equipment The process of expanding the function of the card will become more difficult, often due to the reduction of the operation buttons, the wrong button or the operation error of pressing two buttons at the same time, which further increases the business people who are already quite time-consuming. Language is an intangible cost loss, and for most users, if they need to use a card-type electronic information device when driving or performing other behaviors that require concentration, when changing the card , will make the user unable to focus on driving and other behaviors and need to be distracted to change the card, which will easily cause dangerous incidents, and because the electronic information device needs to be turned on and off every time the function expansion card is changed, this The current change caused by the action is easy to damage the internal parts of the electronic information equipment, thus shortening the service life of the electronic information equipment
