Embodiment Construction

[0013] The present invention will be described in further detail below through specific examples and in conjunction with the accompanying drawings.

[0014] like figure 1 F1 and F2 shown in the figure are power sockets, which are convenient for the wireless transmission circuit to be connected in series with the F7 circuit of the air conditioner, F3 is the sampling and power conversion circuit, F4 is the rectification, filtering, and voltage stabilization circuit, F5 is the coding circuit, and F6 is the high-frequency data launch circuit.

[0015] figure 2 When the shown air-conditioning compressor works, the current reaches more than 4 amperes. After being added to the primary side of the transformer B1, a certain voltage will be induced on the secondary side of the transformer B1 according to a certain turns ratio. The present invention is set to a voltage of 16.5V. Fuse FU, bridge VD1-VD4 rectifier, C1, C2 low-frequency high-frequency filter, 12V stable voltage output th...

Abstract

The invention relates to a wireless control circuit for an automatic thin-wall copper tube fresh air handling machine. Traditional wireless control circuits are mostly active circuits, especially trigger signals are from large-capacity electric equipment including an air conditioner and the like, and therefore the defects that a sampling circuit is complex, a control circuit is prone to being interfered by the outside world and a control distance is short exist. According to the wireless control circuit, when an air conditioner compressor is started and works, currents serve as a signal source and by the utilization of the current transformer principle, and voltage induced by a secondary side is processed and then serves as a signal source of the control circuit and a power source provided for a transmission circuit. A control signal is coded and then transmitted, passive and wireless data transmission and reception are achieved, and then controlled electric appliances including the fresh air handling machine and the like are controlled. The wireless control circuit for the automatic thin-wall copper tube fresh air handling machine is simple, passive, low in code coincidence, reliable in control and long in control distance.

Description

technical field [0001] The invention relates to a control circuit, which is used for the wireless control of the thin-walled copper tube automatic fresh air blower, and can also be used for the control of other electrical appliances. Background technique [0002] There are many wireless control circuits, such as infrared and wireless control circuits, but these circuits are all active circuits, especially the trigger signal comes from large-capacity electrical equipment such as air conditioners, and the sampling circuit is complicated, the control circuit is susceptible to external interference, and the control distance is not far, etc. insufficient. Contents of the invention [0003] The purpose of the present invention is to provide a wireless remote control circuit for thin-walled copper tube automatic fresh air blowers, etc., and propose to use the current as the signal source when the air conditioner compressor is started and working, and use the principle of current ...
