Counting type special power supply scheme

Abstract

The invention provides a counting type special power supply scheme, and belongs to the technical field of electronics. The power supply is formed by a voltage stabilization unit, an OR gate input unit, an auxiliary power supply, a time unit, a logic unit, and a power amplifier unit. Input of the voltage stabilization unit is connected with a system power supply, and output of the voltage stabilization unit is connected with a power end of an integrated circuit of a gate circuit. An output end of the OR gate input unit is connected with a first input end of the auxiliary power supply unit, and output of the auxiliary power supply unit is connected with two paths, one path is connected with a power end of a counter in the time unit, and a second path is connected with the input end of a differentiating circuit of the counter. The output end of the differentiating circuit triggers a zero clearing end of the counter. A single-bit output end of the counter triggers a first input end of the logic unit, and output of the logic unit is connected with the power amplifier unit. The output of the power amplifier unit is connected with a load decoding integrated circuit. The counting type special power supply scheme has multi-circuit control end input, and is used with a plurality of decoding integrated circuits in a matched manner, theoretical probability of one-time decoding output is eradicated, and possibility of cracking is greatly improved.

Description

technical field [0001] It belongs to the field of electronic technology. Background technique [0002] The present invention is an important circuit among the achievements of the enterprise, and the circuit also has a wide range of applications in electronic circuits. The present invention proposes a special power supply composed of integrated circuits. [0003] For example, in remote control technology. Increasing the confidentiality level is a very important key point for researchers. The present advanced code is a rolling code, which is characterized in that there are many address codes, and the code is changing, so it is much more difficult to crack than a fixed code. Although it is theoretically analyzed that if the launch is completed according to all the laws of the rolling code, it will take more than a thousand years to crack it, but if it is tested and launched according to the random law, there is still a probability of cracking in theory. Its reason is that w...

Problems solved by technology

[0005] However, the current decoding integrated circuit products do not meet the requirements of this new unit. There are two types of decoding integrated circuit performance, one is non-locking type, and the other is locking type.

[0006] Although the non-locking type decoding integrated circuit can realize automatic clearing, the disadvantage is that the sensitivity is relatively lower than that of the locking type, which is mainly reflected in the long distance, and it is also that the locking type integrated circuit can be received within a long distance. signal, but the non-locking type does not receive the signal

Second, the clearing time is too short to meet the signal synthesis time

The third is that the length of the clearing action time cannot be adjusted, and it cannot satisfy the synthesis when the code is many times

[0009] 1. Three procedures must be completed before and after triggering: first, supply power to the load, then turn it off, and then turn it on again

[0010] 2. Must have three time constants

[0014] Therefore, there are currently no ready-made products that meet such requirements. If you want to design, it is also full of difficulties, and you must carry out comprehensive innovation.
