Description

But mysterious scales are added

V. Description of the Invention (1) Field The present invention relates to a wireless communication device and a multi-portable device 2 for a mobile phone. , And more specifically, the background. The rapid development of wireless communications has made personal digital assistants more popular. However, for various reasons, such as a mobile phone, and a user holding the phone at the same time, there are still many inconveniences, which results in that the user must carry multiple branches at the same time = Ermen Bluff is quite common and inconvenient. "E-reading" is not only a waste, but to solve the problem that a single user has multiple sets of door switching devices, it is installed in a mobile phone. It can switch between different decks, and then switch electronic switches. , While the technology achieves the purpose of a single machine can switch multiple door numbers :: No. 2. Such points. Due to the modification of the card holder, many defects of the mobile phone p2 have been changed 'and are limited by space; J is ":: Switching between shell club seats may cause bad contacts or use? When changing the battery of different cards It is also easy to damage the deck. Due to the above :, 疋: phenomenon, when the power loss, supply, power, may not be increased, you must turn off and on again when the electronic part number is changed, causing "a few." When switching gate = switching gate number 'can avoid the above-mentioned multiple numbers of subscription telephones, it is not necessary.

Overview The job is a shared device number. The purpose of this creation is to propose that in the case of multiple phone numbers of a mobile phone without changing the phone card, the door can be quickly switched. A mobile phone device can be used more to share the same phone book. A ^ door-to-door device that lets 4 newsletters. Difficulty 丨 J Gates 5 when using this mobile phone dream department π: ® a multi-number IC card to achieve the purpose of switching multiple numbers. The multi-port number sharing device for central processing of a single-access mobile phone includes an integrated unit, the two reusable storage units and the two re-writable memory shared data, and the 9 vulnerabilities respectively store a number of shared and Non-cockroach, for face-to-face mobile phone d: receiving, streamer, second input number and reset signal, the reset two input ports respectively receive clock signals. " 7 Tiger can trigger the central processing unit switching door. Detailed description. The central processing unit i is not the original creation. Connection 2; a preferred embodiment, which includes a random access memory 5. , The m-write memory 30 and 40, and 24, and-external bus 26, U = 1G has two inputs 槔 22 mobile phone device 20 when transmitting =; connected to the mobile phone device 20 f pulse ^ ring and reset Signal

Description of the invention (3) _ ^ Ports 22 and 24 are used to switch the door number of the central processing unit. May repeat # ^ The reset signal is used to control the data, which is convenient for the door: Ϊ; write ;; body 30. Save the shared data of the non-shared piece of phone card, such as electricity :: overwrite memory 40 to store phone card Re-enter these data rooms again 'so that each "door number does not have to be stored in a repeatable erasing bang." The unique data of each door number is stored in a repeatable == 3〇, and other data processing units that can be shared Store data during 1G calculation. ^ Machine access ° The flow chart of the hidden system for the operation of this central system is the first known technology. In step 60, the m diagram starts as Xi Rwn and the second advanced power reset. 、 Set the input / output No Λ record: Initialize the body, then step 62 detects whether the mobile phone device sends a reset signal. If not, go back to step 62. No

In step 64, the central processing unit 10 sends Zhongfeng in V Φ ^ ^ ^ 1Λ.-^ ^ ® is indeed a substring, and then in step 66: waiting for the finger of the mobile phone device 20 to be received, then step 68 Judgment: the instruction system is a general instruction or a switching instruction. If it is a general instruction, step 7: geography the general instruction, and then return to step 66 to continue to receive the instruction. If ^ step 68 is a switching instruction, step 72 Set the database to take out the data and complete the data setting, that is, switch to the new door number, and then return to step 6 6 and continue to wait for receiving instructions. The gate number can be switched by using p 丨 N code or internal menu. As shown in the third figure, use a number? 1 (: A low-voltage single-chip 80 of 16F84 and a chip 82 of 24LC16B are used to implement the device of the first figure. The chip 80 provides a central processing unit and the chip 82 provides re-writable memory. This device is Makes a 1C card 84. Thanks to the single use

[发 鲜 正 补 色 __ V. Description of the invention (4) One IC card, and all the door numbers and information are stored in the C card, so there is no need to modify the appearance or casing of the mobile phone device, and it is not necessary Adding a circuit can achieve the purpose of switching multiple door numbers, without the problems of mechanical failure or poor contact and insufficient power. As shown in the figure, the fourth leg of the chip 80 is connected to the second contact C2 (MCLR) of the 1C card 84, and the fifth leg of the chip 80 is connected to the first to fourth legs and the seventh leg of the chip 82. And connect to the fifth contact C5 (Vm) of the 1C card 84. The tenth leg of the chip 80 is connected to the fifth leg of the chip 82. The eleventh leg of the chip 80 is connected to the sixth leg of the chip 82. To connect, the 12th and 16th pins of the chip 80 are connected to the 3rd contact C3 (RB6) of the 1C card 84, the 13th pin of the chip 80 is connected to the 7th contact C7 (RB7) of the ic card 84, and the chip 80 The 14th pin of the second chip is connected to the 8th pin of the chip 82, and is connected to the first contact C1 (Vcc) of the 1C card 84. This 1C card 84 can hold up to 16 SIM card door numbers at the same time, and the flash memory 82 used therein can be reused 10 million times, which is very stable and will not crash. The process of using the 1C card 84 is explained below. During cold boot, put the IC card 84 into the mobile phone device 20, and then turn on the power. Enter the PIN code as required. The system will automatically switch and set the phone book, short message, card number and other data according to the p I n code. The telephone device 20 starts to operate. If you want to switch the door number in the power-on state, select the switch card from the menu of the phone, and then enter the PIN code according to the requirements. The system automatically switches and sets the data such as phonebook, button information, and card number according to the p 丨 N code. Mobile phone Device 2 〇 Search again. In this way, switching the door number is not only simple and fast, but also does not need to be shut down and restarted. The above description of the preferred embodiment of this creation is for clarity

说明, poor explanation (5) purpose without thinking to limit this creation to the exact form disclosed, based on the teaching of j or learning from the examples of this creation to modify or: the principles of each creation and let you be familiar with the item Technology; greed, practical ^, human-centered creation is selected and described in practical applications.
