Description of the invention () The invention is a method and circuit addition (1) for finding and locking the code of a bird ’s universal controller, which is the eighty-fifth-◦ No. 8441 "Universal remote control" Method and circuit for automatic code finding and locking of the device "(1) Profit, the present invention is mainly to solve the design of the original mother chestnut when the battery's electrical calendar current is insufficient, when the battery is low enough, or when the battery is insufficient to replace the battery • The original stored memory code will therefore be eliminated. • In the central processor itself or in the peripheral circuit. • Add a read-only memory (E EPrOM), so that the previously stored memory code can be used without power. It still does not disappear, and the memory is reset again without supplement, which makes the present invention more convenient to use. At the same time, a computer display * is added in the peripheral circuit to double the computer use. It is indeed highly creative and available. Industrial utilization methods and circuit designers. According to the design of the original mother case, the control circuit is mainly provided with a central processing unit. The auxiliary memory device of the central processing unit records all electrical products and the frequencies corresponding to the various brands. After controlling the electrical products, press the setting chain to enable the central processor to perform a full-automatic fast code-finding action. When the correct frequency is not found to cause the electrical appliances to switch on and off, the central processor will continue to automatically launch different according to the records. Frequency until the power supply of the device to be controlled has a response of ON (ON) or OFF (OFF), indicating that the determination is complete, and can be locked by pressing a key or installing a reflector on the appliance to automatically adjust the setting. In addition: In order to make the limited pressing chain have multiple functions, this remote control is also equipped with a special function button. Pressing this button can make the same button produce multiple different functions. M achieves the multiple button effect and is convenient to replace all electrical appliances. The remote control can also be used as a computer with special functions and press the setting of 设定. It also has the function of timing remote control; therefore, the present invention not only has # 2 A paper size is subject to China Store Standard (CNS) A4. (210X297 mm) Please read the note below. Printed by the Central Bureau of Standards of the Ministry of Economic Affairs-Industrial and Consumer Cooperatives. 46 9694 A7 B7 Industrial and consumer cooperative seal «V. Invention * Description () Fully self-explanatory and quick release, which can improve the troublesome and inconvenient shooting process of the search process of the Ma You controller, Jfec replaces all the devices of the controller, and has automatic The setting and timing functions can effectively increase the convenience in use, and at the same time-can be multi-purpose and also used as a calculation-it is indeed a highly creative method and Kushiro designer that can be used for production and entertainment. The method of the original mother has been superior to the design of various types of traditional communication controllers. It has been detailed in the original mother case. The inventor's design to solve the problem of the design of the original mother's dog in the battery is insufficient. At the next time, or the lack of strength to replace the neck of the pool, the problem of the memory code that has been stored in the past will disappear, so I will concentrate on it, relying on its many years of experience in research and development and distribution of the products of Feiji and Feng Gong With the professional knowledge, I finally developed a "method and method for automatically respecting and locking the universal controller" according to the present invention. (I) I hope to provide the present invention to effectively solve the design of the mother-of-pearl in the pond. When the insufficiency of flow is already below the level, or the lack of force is replaced, when the pool is replaced, the previously saved code will disappear, and it can also be used as a computer user. The main purpose of the present invention is to add a read-only eaves "I (E EPROM)" to the central processor itself or the peripheral circuit, so that the memory code originally stored in the brain will not disappear without power Without having to write a new setting record, so that the present invention is more convenient in use. Yet another object of the present invention is to enable a general controller to double as a computer user by adding a computing indicator to the circuit. In order to make your reviewers better understand the structural features of the present invention and their special functions, they are described in detail in conjunction with Figure M below: 1.

A universal remote control (1), the circuit for automatic code lock of the device includes a central processing unit, and the central processing unit is divided into a data memory, a program table memory, a computing element, a time control device, and an interrupt control device. The data memory can record the search frequency of all brands and products. The program memory can record the key finding function that a particular brand product should have, and it can provide the array matrix data of the corresponding function of each key. Function, the time control device can control the waiting lock interval, and the search interruption control device can search for and lock when the frequencies match, the main ones are: a read-only memory is set in the central processing unit, so that The previously stored memory code does not disappear even when there is no power supply, and there is no need to reset the memory when there is no power and battery replacement; By using the various voltages provided by the power generator and the time counting pulses provided by the oscillation generator, the central processor can start a full-automatic and fast search when the remote control is pointed at the electrical product and the set key is pressed. Take out the frequency data of various products and brands in the memory, and convert it into a transmission signal, which is driven by the indicator light and the transmission output device to the electrical product. When the electrical product has a switching power supply, it means that the rate is consistent and interrupted. Seek action, on the contrary, continue to take out the next piece of data by the accumulation of computing components and send the corresponding frequency signal, and when you find the correct frequency, you can press any key to lock, or add one to the power supply of the electrical product you want to control The “reflector” makes it reflect an electromagnetic wave to control the remote controller to automatically lock. After the lock is completed, the program table memory can be used to take out the key function matrix that the specific brand product should have, and complete the function setting of each key. 2.
