Embodiment
In order to more clearly describe technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
The present invention is primarily of micro controller module (MCU), and OTPROM (One-TimeProgrammableROM, can one-time programming ROM (read-only memory)) module, infrared transmission module and hardware scanning module etc. form (as shown in Figure 2).Wherein, the ROM (read-only memory) of the other types such as mask ROM can also can be adopted by one-time programming ROM module.
Micro controller module major function is by Instruction decoding, the process such as deposits, and produces corresponding control signal and sequential, the function that the program that completes is corresponding.
OTPROM module is mainly used in the pattern data of storage program and remote control, and it is the ROM (read-only memory) supporting write-once.
Infrared transmission module is mainly used in remote signal emission process, and there are three low pressure detection modules (LVD) inside, can open multiple drive power circuit (as shown in Figure 1) according to different voltage.
Hardware scanning module is mainly used in coordinating software to complete waking up and determining effective button system.
The drives structure (as shown in Figure 1) of the infrared transmission module in the present invention is formed primarily of three low pressure detection modules and four stage drive circuits (comprising an initial driving circuit and three secondary drive circuit).IROUT is the remote control pattern data that MCU exports, and REMOUT is infrared emission signal, launches infrared remote-controlled signal for driving power valve.
Wherein the target voltage of three low pressure detection modules is respectively V1, V2, V3 (successively decreasing successively), and when voltage is greater than target voltage, the output Y of low pressure detection module remains " 1 ", once voltage is less than target voltage, exports Y and becomes " 0 ".By or the effect of door, when Y is " 1 ", corresponding driving circuit cuts out; When Y is " 0 ", corresponding driving circuit is opened.
Fig. 1 is the schematic diagram of a specific embodiment.Wherein there are four stage drive circuits in Fig. 1, each stage drive circuit is all made up of multiple NMOS tube be connected in parallel, the structure of each stage drive circuit and the similar of prior art, in this embodiment, first order driving circuit (Q1) is equivalent to initial driving circuit of the present invention, second level driving circuit (Q2) is equivalent to first time of the present invention stage drive circuit, third level driving circuit (Q3) is equivalent to second subprime driving circuit of the present invention, and fourth stage driving circuit (Q4) is equivalent to third time of the present invention stage drive circuit.As VDD>V1, first order driving circuit (Q1) is opened, and is used for driving power valve, and because first order driving circuit keeps driving opening always, it is as initial driving circuit; As V2<VDD<V1, first low pressure detection module controls second level driving circuit (Q2) and also opens, jointly drive power valve by two-stage drive circuit, namely now jointly drive power valve by first order driving circuit (Q1) and second level driving circuit (Q2); As V3<VDD<V2, second low pressure detection module controls third level driving circuit (Q3) and also opens, jointly drive power valve by three stage drive circuits, namely now jointly drive power valve by first order driving circuit (Q1), second level driving circuit (Q2) and third level driving circuit (Q3); As VDD<V3,3rd low pressure detection module controls fourth stage driving circuit (Q4) and also opens, jointly drive power valve by whole four stage drive circuits, namely now jointly drive power valve by first order driving circuit (Q1), second level driving circuit (Q2), third level driving circuit (Q3) and fourth stage driving circuit (Q4).
All gone here and there a protective resistance at the grid of the driving circuits of latter three grades, immediate current when being to prevent multiple drive power circuit from acting on simultaneously is excessive, avoids producing excessive impact to VDD and causing circuit cisco unity malfunction.
