Abstract

The present invention relates to a novel design of radio remote control copying host, it's copying method and frequency counting method. A receiving demodulation circuit is used to receive the radio signal from the original remote control, and after detecting and shaping, output a carrier signal and a coding signal. A microprocessor takes the coding signal as a standard to determine the correct frequency of the carrier signal, and all the frames of the coding signal are stored into memory. After the processing mode is determined, all the frames of the coding signal are transmitted and stored into a keyboard circuit or memory location of copyable remote control designated by the program. With such a design, it is able to not only use a LCD display to directly display the correct carrier frequency and coding content of the original remote control, but also transmit and copy all the received frames of the coding signal into the copyable remote control, thereby eliminating the drawback of copying erroneous or incomplete frame, and thus avoiding the occurrence of an erroneous copy.

Description

46082 A7 B7 V. Description of the invention (/) Printed by the Central Bureau of Standards, Ministry of Economic Affairs, Shellfish Consumer Cooperative, This invention is an innovative design of a radio remote control copy host, its copy method and frequency counting method. It is mainly composed of power circuit, receiving Demodulation circuit, microprocessor, memory, keyboard circuit: It is composed with L CD display. 'It can not only display the correct carrier frequency and encoding content of the original remote control directly on the L CD display, but also because it will receive the original remote control. All the signal frames of the encoder ’s coded signal are copied to the copyable remote control, avoiding the disadvantage of only copying to the wrong or incomplete signal frame, so that the entire copying operation will not cause mis-copying. What the claim refers to. According to the increasing popularity of electronic remote control locks, the radio remote control used for this type of lock has also developed at the same time. Gradually, this kind of radio remote control with ten qualities similar to electronic keys has become a necessity for people's lives. $ Set. In the past, this type of radio remote control was usually only assigned to users with electronic locks. However, for families with at least two people in the general population, a small number of radio remote controls are obviously inadequate, and if they are lost or damaged, In some cases, because there is no backup radio remote control available, it is usually necessary to purchase a new radio remote control 'between' from the electronic lock manufacturer. The inconvenience or tangible loss caused by the radio remote control will never be discussed again. The range is very wide. In recent years, quite a few radio remote controls have been used in the building ’s ban control system. Therefore, this type of magnetic card key is more common and is widely used as a radio remote control by ordinary metal keys. Many manufacturers have designed and manufactured them. Copyable remote control 'This remote control is similar in structure to the aforementioned radio remote control, but it does not contain any data. It must cooperate with a copy host to use a copy host to receive, analyze, and remote control. Carrying frequency and power of each device ^ In comparison with the internal device, the paper size is applicable. National Standard (CNS) Α4 Specification (210X297 mm) 460821

It should be specific, edit the pain, and print the media. 5. Description of the invention (? ·) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs `` Transfer the results to the memory in the copyable remote control $ First, make the copyable remote control have the same coded data as the original remote control and have the same operating performance. Because the operation method of this operation is quite simple and fast, in the recent years, it has been rapidly expanded to various locks or locks in the domestic and foreign markets. People have the remote control caused by insufficient use, loss or damage. The trouble is that the rapid development of the radio remote control copy industry can be described as expanding the more convenient pollution space and benefiting people. · However, due to the simplicity and convenience of copying the radio remote control, the cautious people were surprised by the insecurity brought by the convenience. Since then, several companies have designed a copy of this: < Copy j remote control, which This kind of remote control can't be copied once it is copied from the original remote control. Only the original remote control can be copied again. Although it can satisfy people's psychological insecurity, once the original remote control is lost or damaged, the user will return to the trouble of being unable to copy the remote control in the early stage. Therefore, is it necessary to use a copy-proof remote control? Depending on the choice of the consumer, it is undeniable that this copy-proof remote control has a place in the market. Therefore, the general copy industry often causes the copy to the wrong code because the remote control brought by the user is not the original remote control. The situation of the data makes the copied remote control unusable, which not only causes trouble to the copying business, but also causes some inconvenience to normal users. In addition, due to improper operation or poor signal, the aforementioned erroneous copy situation may also be caused. In order to allow your commissioner to go deeper into the design expertise of the present invention and to further understand the details of the above-mentioned miscopy situation, we are hereby targeting the general market process.

] The start bit (B), and the address and data bit (c) of the start bit (B), thus forming a complete signal frame (D). When a button of the original remote control is pressed, the encoded data corresponding to this button will be modulated and transmitted. The length of the transmitted signal is usually the length of many consecutive signal frames (D), as long as there is a complete and correct signal frame. / D) is received and approved by the control host, and the control host performs corresponding output actions according to the definition of the signal box (D), such as the action of opening or closing the garage. When the original remote control transmits a radio signal representing internally coded data, all the radio signals within the radio signal are transmitted within one to one mile of the signal frame (D) and n rabbit quine or seven 鸯 ㈣H.

Description of the invention (>) Printed and cut by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. And because the signal transmitted by the original remote controller is not only one signal frame, as long as one signal frame is complete and correct, the control host corresponding to the original remote controller can accept and perform corresponding output actions. However, this is not the case for the remote control type remote controller copied by the conventional radio copy host, because the 'microprocessor' of the conventional radio remote control copy machine receives the transmission signal of the original remote control (this The signal has been demodulated by the receiving circuit). It is to detect the j-synchronization signal (because a fixed-width low-potential synchronization signal appears before and after each signal frame), and one or more A signal box; and compare whether each signal box is the same, if the same indicates that the signal box is correct, then transfer one of the signal boxes to the memory of the copyable remote control, so that the copy job is completed, if If the result of the comparison is not, it indicates that the signal frame that may be picked up is missing. At this time, the operation must be performed again until the correct signal frame is obtained. However, the conventional radio remote control copy host described in the previous paragraph, although some have a signal frame that is confirmed by the microprocessor to confirm that the wheel is to be stored.
