Description

A kind of intelligent switch with zero crossing detection function
Technical field
This utility model relates to intelligent switch technology field, particularly relates to a kind of intelligence with zero crossing detection function and opens Close.
Background technology
Existing actual electric circuit is of a great variety, and the instant starting currents in most of electric circuits is big, causes intelligence Relay contact in on-off circuit burns out and bonds, and can effectively reduce in Intelligent switching circuit after employing zero passage detection principle Relay damaged.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of intelligence with zero crossing detection function Switch.
In order to realize object above, this utility model be the technical scheme is that
A kind of intelligent switch with zero crossing detection function, drives including zero cross detection circuit, switch power module, relay Galvanic electricity road, LDO circuit and processor, wherein said zero cross detection circuit and switch power module are all connected with zero line and fire Line, described zero cross detection circuit electrically connects with processor and is transmitted across zero-signal to processor, described LDO be connected to processor with With the input voltage of stabilized treatment device between switch power module, described relay drive circuit is connected also with switch power module It is connected with processor to receive the control signal of processor simultaneously.
The beneficial effects of the utility model are: the intelligent switch with zero crossing detection function of the present utility model, its zero passage Testing circuit has the effect of zero passage detection, when current waveform is changed through zero-bit from just half circumference negative half period, and processor connects Send corresponding control signal to relay drive circuit after receiving zero cross signal, make the relay adhesive in Intelligent switching circuit, Effectively reduce the impact to Intelligent switching circuit repeat circuit contact of the instant starting currents of load, prevent in Intelligent switching circuit The burning out and bonding of relay contact.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present utility model.
Wherein, 1-zero cross detection circuit, 2-switch power module, 3-relay drive circuit, 4-LDO circuit, 5-process Device.
Detailed description of the invention
Make the most specifically in conjunction with the drawings and specific embodiments technical scheme required for protection to this utility model Bright.
Seeing shown in accompanying drawing 1, a kind of intelligent switch with zero crossing detection function of the present embodiment, including zero passage detection electricity Road 1, switch power module 2, relay drive circuit 3, LDO circuit 4 and processor 5, wherein said zero cross detection circuit 1 with And switch power module 2 is all connected with zero line and live wire, described zero cross detection circuit 1 electrically connects with processor 5 and to processor 5 Passing through zero-signal, described LDO is connected to the input voltage between processor 5 and switch power module 2 with stabilized treatment device 5, institute State relay drive circuit 3 and be connected and be connected to receive with processor 5 simultaneously the control letter of processor 5 with switch power module 2 Number.
Its zero cross detection circuit 1 has the effect of zero passage detection, when current waveform passes through from just half circumference negative half period conversion During zero-bit, processor 5 sends corresponding control signal to relay drive circuit 3 after receiving zero cross signal, makes intelligent switch electricity Relay adhesive in road, effectively reduces the impact to Intelligent switching circuit repeat circuit contact of the instant starting currents of load, Prevent burning out and bonding of Intelligent switching circuit repeat circuit contact.
The embodiment of the above is only preferred embodiment of the present utility model, and this utility model not does any form On restriction.Any those of ordinary skill in the art, without departing under technical solutions of the utility model ambit, all can profit With the technology contents of the disclosure above, technical solutions of the utility model are made more possible variation and retouching, or be revised as equivalent The Equivalent embodiments of change.Therefore all contents without departing from technical solutions of the utility model, made according to the thinking of this utility model Equivalent equivalence change, all should be covered by protection domain of the present utility model.
