The infrared remote controller is a cheap, small, simple, reliable and effective product. It can effectively resist electromagnetic interference and ensure safe operation of the system. Using remote technology can reduce manipulative difficulty during soil bin testing and realize single operation of the whole system. Practical application many times demonstrated that the infrared remote controller can work reliably and improve work efficiency considerably.Besides control the movement of tester, the soil bin tester driving control system can adjust the tester speed by rule and line, which was impossible to former test equipments. The range can be adjusted from -1.45m/s to 1.45m/s, the positive and minus sign denotes the direction of tester running.
