Accompanying drawing explanation
Fig. 1 is the circuit diagram of communication level control circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of communication level control circuit，Including resistance R1、Resistance R2、Audion Q1、Audion Q2 and diode D1，Described resistance R1 one end connects single-chip microcomputer VCC end and power supply V1 respectively，The resistance R1 other end connects single-chip microcomputer RXD end and audion Q1 colelctor electrode respectively，Audion Q1 base stage connects resistance R2 and resistance R3 respectively，The resistance R3 other end connects power supply V2 and GPRS module vdd terminal respectively，The TXD end of GPRS module connects the resistance R2 other end and audion Q1 emitter stage respectively，The RXD end of GPRS module connects resistance R5 respectively、Diode D1 positive pole and audion Q2 colelctor electrode，The resistance R5 other end connects diode D1 negative pole respectively、Power supply V3 and resistance R4，Resistance R4 other end connecting triode Q2 base stage，Audion Q2 emitter stage connects single-chip microcomputer TXD end and resistance R6 respectively，The resistance R6 other end connects power supply V4；Described diode D1 is Zener diode.
Referring to Fig. 1, when GPRS module TXD is high level, owing to the Ve=Vb of Q1, audion Q1 end, the RXD of single-chip microcomputer is drawn high high level by pull-up resistor R1.When GPRS module TXD is low level, when the TXD of single-chip microcomputer is high level, due to the Ve of Q2 > Vb, audion ends, and pull-up resistor R5 moves the RXD of GPRS module to high level.
When the TXD of single-chip microcomputer is low level, owing to the Ve of Q2 is when the resistance of choice set electrode pull-up resistor, needs to consider the current drain on the traffic rate of input and pull-up resistor, reduce pull-up resistor resistance, communication speed can be improved, obtain shorter switch time；And increase pull-up resistor resistance, then extending switch time, communication speed reduces, so technical staff can select the most voluntarily.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
