Description

A kind of signal emission pen that adopts luminous energy to drive

Technical field:

The utility model relates to the wireless signal transmitting device technical field.

Background technology:

The wireless signal transmission of seeing in the market (device) pen, its mounted inside is by the battery of a 12V, a signal transmission circuit plate of being made up of separation components and parts such as resistance, electric capacity, triode, telefaults.The weak point of sort signal emission pen is that the work efficiency of separating component is lower, the energy consumption height, because its design must be adopted the high-tension battery of 12V, and this battery is uncommon and cost an arm and a leg on market, bring a lot of troubles to the user, but also can cause environmental pollution; In addition, its separate type components and parts design has also improved the complicacy on the product processes, causes production efficient and product quality not high.

The utility model content:

The purpose of this utility model provides a kind of signal emission pen that adopts luminous energy to drive with regard to being the weak point that exists at prior art, it has, and volume is little, assembling is simple, firm and durable, characteristics with low cost.

For achieving the above object, the signal emission pen that employing luminous energy of the present utility model drives includes a body, pcb board, switch, battery, radiating circuit, telefault, wherein, described battery is the amorphous silicon light energy battery, and radiating circuit is for regularly deciding frequently to produce circuit.

Described radiating circuit adopts the integrated timing of CMOS frequently to produce circuit surely, and its inside has electric power management circuit, trigger circuit, timing circuit, frequency generating circuit and amplifying circuit; Electric power management circuit links to each other with the amorphous silicon light energy battery, and the input end of trigger circuit links to each other with switch, and the output terminal of trigger circuit and timing circuit links to each other with the input end of amplifying circuit via frequency generating circuit, and the output terminal of amplifying circuit links to each other with telefault.

Described telefault is connected in series an inductance.

The beneficial effects of the utility model are: it adopts regularly frequency setting circuit as radiating circuit, frequency stabilization, signals collecting are more reliable, not only simplify product processes, dwindled small product size, and easy to assembly, firm and durable, simultaneously, because it has adopted the amorphous silicon light energy battery, have again that energy consumption is low, an environmental protection, the signal emission duration is long, signal transmission power is big advantage.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in Figure 1: the signal emission pen that employing luminous energy of the present utility model drives includes a body 10, pcb board 20, switch 30, amorphous silicon light energy battery (being solar cell) 40, radiating circuit 50, telefault 60, electric capacity 70; Wherein, radiating circuit 50 is the regularly fixed integrated chip frequently of CMOS, and regularly fixed integrated chip inside frequently has electric power management circuit 51, trigger circuit 52, timing circuit 53, frequency generating circuit 54 and amplifying circuit 55; Amorphous silicon light energy battery 40 links to each other with electric power management circuit 51, switch 30 links to each other with the input end of trigger circuit 52, the output terminal of trigger circuit 52 and timing circuit 53 links to each other via the input end of frequency generating circuit 54 with amplifying circuit 55, and the output terminal of amplifying circuit 55 is connected in series via electric capacity 70 and telefault 60.

Principle of work of the present utility model is: close a switch after 30, trigger circuit 52 detect this action, and frequency of notification produces circuit 54 and produces the square wave that sets frequency (as about 170KHz), outputs to the Fout pin through amplifying circuit 55; Simultaneously, timing circuit 53 begins counting, reach the predefined time (such as 100ms) after, disconnect frequency output immediately, avoided the power supply energy waste of closing for a long time and causing like this because of switch 30.

The telefault 60 and electric capacity 70 connected in series with amplifying circuit 55 output terminals, by LC resonance, produce higher resonance potential UA at the A point, make UA＞＞(the supply voltage VDD such as the amorphous silicon light energy battery is 2V to VDD, and UA is more than the 10V), like this, the emissive power of telefault 60 can strengthen greatly.
