Description
Technical field
The utility model relates to technical field of circuit control, specifically a kind of Multi-path synchronous output control circuit.
Background technology
In recent years, because a lot of particular device requires that multiple isolation power supply opens synchronous operation, as being applied in ground data terminating machine, rf control unit etc. simultaneously.All will use the problem synchronously opening equipment in various fields, synchronous concept has in digital communication, also has on TV, and TV station has special synchronizing signal to power and signal generator.Its each relevant devices in platform provides synchronizing signal and the power supply synchronization of benchmark, and such as program is all being done in two studios, and their vision signal must be synchronous, otherwise both just can not switch smoothly.And their synchronous benchmark are just powered and signal generator from synchronizing signal accurately.
Utility model content
The purpose of this utility model is the problem that the work of solution electric equipment can not be synchronous, multiple device synchronization is under given conditions powered, unanimously works.
The purpose of this utility model is achieved in that a kind of Multi-path synchronous output control circuit, comprise charging time delay module, signal controlling module and switch control module, described charging time delay module is connected with switch control module by signal controlling module, and switch control module carries out Synchronization Control to output circuit unit; Wherein, the time delay module that charges comprises relay, power supply and electric capacity; Signal controlling module comprises triode, resistance and signal optical coupler; Switch control module comprises MOS switching tube and output; The normally closed electric shock of relay is connected with electric capacity, and electric capacity is electrically connected with power supply; Described triode one end is connected with electric capacity and power supply, and the other end is electrically connected with signal optical coupler by resistance; The other end of signal optical coupler connects MOS switching tube.
Described relay model is AC220-230V relay.
Described electric capacity model is 50V10; Triode model is 2N2222; Signal optocoupler type number is T1L1117; MOS switching tube model is FQA90N15.
Described relay quantity is 1; The quantity of signal optical coupler is more than 3, and with the quantity one_to_one corresponding of MOS switching tube.。
The utility model has the advantage of: 1. function admirable, reliability is high; For the shortcoming of conventional method, carry out brand-new design and perfect, thus effectively improve the synchronism output consistency of power supply, precise control and reliability; 2. simple circuit, working stability, adopts basic separate piece to form, and the antijamming capability of whole circuit is also very strong, and the value of the corresponding device that only need calculate by former design theory assembles, and can meet the requirement of technical indicator; 3. applied widely, the utility model has can delays time to control, the feature such as circuit is simple, precision is high, synchronous consistency is good; Prevailing operating state is not by the impact of rear class equipment; Greatly widen the occasion of its application.
Accompanying drawing explanation
Accompanying drawing 1 is circuit theory diagrams of the present utility model;
In figure, J is relay; C1 is electric capacity; A1 is triode; T1-Tn is signal optical coupler; Q1-Qn is MOS switching tube.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
The utility model mainly comprises charging delay component, signal control portion, switching controlling part grade.
By the charging of powered on moment to electric capacity, the voltage of control signal switch control terminal, makes Signal-controlled switch Time Delay Opening, and then the optical coupler controller in control circuit is all opened simultaneously, complete the Synchronization Control to metal-oxide-semiconductor in main output circuit, make winner's output circuit synchronism output.
After equipment energising, export 1 all first can not export to output N, relay J obtains electric, normally-closed contact is by giving electric capacity C1 discharge condition separately, + 5V power supply is charged to electric capacity C1 by R1, when C1 charging end L point voltage can make triode A1 conducting along with charging is elevated to, make+5V power supply by R2 by optocoupler T1 to TN conducting simultaneously, thus make the synchronous conducting of optocoupler T1 to TN control Q1 to QN, so just achieve the synchronous conducting exporting and control metal-oxide-semiconductor, the switch of multiple-channel output is opened simultaneously, completes multiple-channel output Synchronization Control.
In sum, the utility model passes through charging delay circuit, after output 1 is set up completely to the main circuit exporting N, then conducting while further control signal optical coupler, and then control output mos pipe switch is synchronously opened, and completes multiple-channel output Synchronization Control.Have that delay time is controlled, circuit is simple, precision is high, the synchronous feature such as accurate, this control unit is mainly used in the circuit of power requirement synchronism output.
Last it is noted that obviously, above-described embodiment is only for the application's example is clearly described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of amplifying out or variation be still among the protection range of the application's type.
