| Abstract: | In order to meet the requirements of multi-channel temperature measurement in the field of armored vehicle test evaluation and condition monitoring,a project based on MC9S12DT128 and AD7794 is proposed,which can be extended by the CAN-bus.The principle of temperature measurement was analyzed,and the key circuit and some soft codes for temperature acquisition using AD7794 were given.The setting method of the mode register and configuration register of AD7794 and the measurement flow chart were described.The experimental and practical application results show that the system has high precision,low cost,good extensibility,strong adaptability to harsh environments,and high reliability,which can be widely used in other fields. |
