Integral multi-program power switch

Abstract

The invention discloses an integral multi-program power switch, and belongs to the field of electronic techniques. The power switch is composed of a OR gate input unit, a first time constant unit, a complementation unit, a second time constant unit, a power amplification unit and a voltage stabilizing unit, wherein the first time constant unit is a circuit composed of an integral circuit and an adapter; the complementation unit is an amplification circuit formed by an NPN triode and a PNP triode connected with each other; the second time constant unit is a circuit composed of a differentiating circuit and an adapter; and a multi-digit input end of the OR gate circuit is connected with a preceding stage control source, and then connected with the first time constant unit, the complementation unit and the second time constant unit. The second time constant unit feeds back to the input end of the complementation unit, and the output end of the complementation unit is connected with the power amplification unit and then connection with the voltage stabilizing unit to serve as final output. The integral multi-program power switch provided by the invention is mainly matched with a decoding integrated circuit as a whole which has a high decoding level and thus completely eradicates cracking by conventional one-time decoding, and can also be applied to other fields.

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. [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 when cracking the signal transmitted by people, it still belongs to the decoding signal p...

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, power is provided outside the load, then it is turned off, and then it is turned on again

[0010] 2. Must have two important 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.
