Embodiment
Monitoring harmful gases remote operated vehicle structural representation as shown in Figure 1, the harmful gas detection module is installed on the remote operated vehicle, the harmful gas detection module comprises harmful gas concentration detection and wireless transport module, wireless video transmission module, and 4 wheel driven moving of car wireless control module is arranged on the remote operated vehicle.
Harmful gas concentration detects the direct supply that comprises harmful gas sensor, STC single-chip microcomputer, wireless transport module and power supply with wireless transport module, and harmful gas sensor is selected MQ135, and ammonia, sulfide, benzene series steam are had higher sensitivity.Also can adopt other sensors as required.It is larger to reveal gas concentration, the magnitude of voltage higher (between the 0-4V) of MQ135 output.The voltage signal of MQ135 output is input to the STC single-chip microcomputer by 12 ADC modules, and by RX, the TX pin is connected with the 433MHz wireless transport module STC single-chip microcomputer, gas concentration signal is launched 300 meters of wireless transmission distances again.Certainly, can according to the difference of revealing gaseous species, change different gas concentration sensors.
The wireless video transmission module: this module is supplementary module, is in order to obtain the video image at gas leakage scene.Adopt the wireless camera of 2.4GHz, carry antenna, built-in rechargeable lithium battary, but continuous working 4 hours, and have infrared night viewing function.The image that gathers can transfer back on the notebook computer that is placed on the safety zone in real time, and notebook computer one end adopts the video reception module of USB interface.300 meters of wireless transmission distances.
4 wheel driven moving of car wireless control module: in order to increase the obstacle climbing ability of dolly, adopt four-wheel drive.4 motors are the high-quality direct current generator, and rated operational voltage 6V carries the 1:100 speed-changing gear box, has further improved output torque.4 motors adopt 2 L298N to drive chip drives, drive finned on the chip.Motor, the hardware line graph of driver and controller be as shown in Figure 2: wherein, (1) 433M wireless transport module and STC single-chip microcomputer are by RX, and the TX pin connects, and is used for receiving the motion control instruction of host computer.(2) P1.0 of single-chip microcomputer, P1.1, the P1.2 pin is exported respectively PWM pulse-width signal and direction control signal, in order to the rotating speed of controlling No. 1 motor (corresponding the near front wheel) and No. 2 motors (corresponding left rear wheel) with turn to.(3) P2.0 of single-chip microcomputer, P2.1, the P2.2 pin is exported respectively PWM pulse-width signal and direction control signal, in order to the rotating speed of controlling No. 3 motors (corresponding off-front wheel) and No. 4 motors (corresponding off hind wheel) with turn to.(4) in order to improve the stability of kinetic control system, taked following measure: adopt dual power supply, i.e. controller power source and machine operation isolated from power; Adopt optocoupler to connect between controller and the driver, controller is played a protective role.
