The workflow of described control mechanism is: single-chip microcomputer receives the movement pattern data of support bracket of display device by communication interface, be stored in the data register, single-chip microcomputer receives the control command that control panel sends by the control command interface, in data register, search corresponding movement pattern data, and be committed to signal transmitting unit, signal transmitting unit is sent to each drive circuit with described movement pattern data, each drive circuit is controlled corresponding motor rotation, feedback unit obtains the actual speed of motor, and give single-chip microcomputer with described actual speed feedback information, the rotating speed regulation unit of single-chip microcomputer is adjusted current tach signal according to the actual speed information of described motor, send to drive circuit via signal transmitting unit again, realize stable the moving of driven by motor support bracket of display device thus according to the selected motor pattern of control panel.
In order further to reduce product cost, the drive circuit 232 of drive motor does not adopt the scheme of integrate motor driving chip, but adopts driving mode as shown in figure 14.
Structural representation as Figure 14 support bracket of display device embodiment's of the present invention drive circuit, if turn signal is 0, on the one hand, first not gate 3201 be input as 0, then its be output as 1, the first or door 3201 be input as 1, thereby, first or door 3201 output be 1, again because field effect transistor Q1 is the P-channel field-effect transistor (PEFT) pipe, so Q1 ends; Meanwhile, the 3rd not gate 3203 is output as 0, and Q4 input low level, triode Q4 are N channel field-effect pipe, so field effect transistor Q4 is cut off, so the circuit of Q1 to Q4 can not conducting.
On the other hand and since turn signal be 0, the three not gate 3203 be input as 1, be output as 0, therefore second or of door 3204 be input as 0, another one is input as tach signal, wherein, when rate signal was 0, Q3 was input as high level, Q3 conducting; Meanwhile, first not gate 3201 is output as 1, and the input signal of Q2 end is a high level, and the Q2 conducting is in the circuit turn-on of the high side fet Q3 of diagonal positions to low side fet Q2, and electric current flows through motor from right to left, the motor rotation.
In like manner, if turn signal is 1, the circuit of Q3 to Q2 can not conducting, is in the circuit turn-on of the high side fet Q1 of diagonal positions to low side fet Q4, and electric current flows through motor from left to right, the motor counterrotating.
Cooperating of the turn signal that produces by PWM tach signal and programming, realized the control of motor steering and rotating speed.
Because above-mentioned direct current motor drive circuit does not possess dead band control, overvoltage/under-voltage, overcurrent, protective measure such as overheated, but under use condition normally, in general these protective measures can not wanted, and therefore, replace a total discharge cock and get final product.
