Problems solved by technology

[0002] Compared with infrared remote control, wireless remote control has the advantages of strong penetration and long communication distance, so many remote control switch products now use wireless radio frequency remote control technology; at the same time, in order to make the control more intelligent, many products are now based on wireless remote control. It integrates manual control functions, such as light touch buttons, ordinary mechanical switches, etc. Most of its circuit structure adopts the direct connection of light touch buttons or ordinary mechanical switches with the remote control processing circuit, and the key switch signals are collected through the program or related chips, and then The disadvantage of this is that once the remote control processing circuit fails, the buttons or mechanical switches cannot be controlled, so the purpose of intelligent control will not be achieved.
This technical solution uses a double-coil relay, which is not only costly, but also the corresponding circuit is relatively complicated
[0005] To sum up, the current intelligent switch control system has certain defects, and still cannot meet the needs of people's intelligent control.

Embodiment 1

[0020] like figure 1 As shown, an intelligent switch control system is composed of an RF remote controller a, an RF receiving module 1, a learning button 2, a CPU 3, a control module 4, and a dual control switch 5. Its characteristics are as figure 2 As shown, the CPU3 used in this embodiment is a PIC12F629 single-chip microcomputer; the control module 4 is mainly composed of a resistor R2, a transistor Q1, a diode D2 and a relay K1; the frequency of the RF remote controller a is 315MHZ or 433MHZ; the RF receiving module 1 is The radio frequency receiving module with the same frequency as the remote control; S1 is the learning button, and the light-emitting diode D1 is used to indicate whether the learning is successful.

[0021] The two contacts of the relay K1 are respectively connected with the two contacts of the dual-control switch K2 to form a dual-control mode, so that the load LAMP can be controlled freely. After using the remote control to turn on or off the load, t...

Embodiment 2

[0024] like figure 1 As shown, only need to replace CPU3 with EM78, 51 and other single-chip microcomputers, and add a 24C01 or 24C02 memory chip, the rest of the working principle and connection method are the same as the first embodiment, and the same effect as the first embodiment can also be achieved.

Embodiment 3

[0026] like figure 2 As shown, the control circuit composed of R2, Q1, K1, and K2 is only a single control output. If multi-channel control is required, just add the same circuit as the control circuit of R2, Q1, K1, and K2, and the rest will work. The principle is the same as that of the first embodiment, and multiple control outputs can be achieved to control multiple loads.

Abstract

The invention belongs to the field of wireless remote control and particularly relates to an intelligent switch control system which can control a load by wireless remote control and a common mechanical switch simultaneously. The system comprises a RF remote controller a, an RF receiver module 1, a learning key 2, a CPU 3, a control module 4 and a double-control switch 5. The invention solves the technical problem by adopting the technical scheme and has the advantages that firstly, one remote controller key can control a plurality of intelligent switches, and vice versa, a plurality of remote controller keys can control the same intelligent switch; secondly, ganged control to the load is realized by the common mechanical switch and a relay, and thereby free control to the load can be realized even a certain circuit fails; and thirdly, a double-coiled delay is changed into a single-coiled relay, thereby simplifying a circuit structure and reducing failure probability. In addition, the invention has simple structure and stable and reliable performance.
