laser pointer will be introduced in details in the following.
According to design requirements to create the entity to meet the above options car. Figure 3.2 part of the mechanical structure of Figure 3.4 power supply module program: Laboratory wired power supply voltage regulator chip, its advantages can be stable 5V voltage, but accounted for 10 of the intelligent car control based on laser detection system designed to use the resource is too large . Option Two: one 7.2V (with the standard) batteries single power supply, while drawing the circuit diagram transformer chip and voltage regulator chip, 7.2V into 5V to provide the electricity use of SCM and other modules. The final selection of programs to facilitate the design and use. 3.5 Servo drive module car steering gear torque, good stability, precise control perspective. The enterprise of laser pointer should know the target of the purchase.
But poor sensitivity, there are serious mechanical hysteresis. Due to the steering gear of the current changes, the interference steering gear can be a separate power supply, and in series between the positive power supply and steering diodes or opto-isolation to prevent the steering gear power supply voltage. This effectively reduces the steering gear of the mechanical hysteresis, so the car to stabilize the fast-moving, the steering gear control using open loop control. Steering gear power supply system is the transformer regulator chip L7805 is to rely on based on the circuit in parallel with the 78L05 to provide steering gear power steering gear and the microcontroller is also connected to, and 6N137 chip series, isolated by optocoupler, and thus prevent recoil current burn SCM. The factory should master the information of supply management of laser pointer well.
At the same time rely on the microcontroller pwm duty cycle to control the operation of the steering gear. Figure 3.3 6N137 schematic control system design system block diagram and working principle of laser detection-based smart car system block diagram is shown in Figure 4.1, the data collected by the laser sensor to complete the detection of black lines, and the form of a voltage signal into the microcontroller IO port 16 5 mA laser reflector head on the pavement to identify seven laser receiver to receive the feedback signal, microcontroller sent signal analysis, processing, issued a directive on the car after treatment to exercise control, to make electric cars in the moving direction can be adjusted [9]. Do perform the purchase of laser pointer well.The workshop notices a lot about the performance control of laser pointer
