| Abstract: | The scheme of the high-precision temperature and determined through analyzing the functional requirements for the The overall scheme and the realization of hardware and software humidity intelligent sensor system ~s meteorological data acquisition system. systems are introduced functions of high-accuracy measurement, automatic： collection, and real-time processing, To realize the Based on the CAN Bus, the main control chip LPC1768 is selected, in combination with the low-power consumption architecture of ARM CORTEX-M3, 1f-bit serial A/D conversion chip AD7792 with low power consumption, and the high speed CAN transceiver SN65HVD230 with low power consumption. Compared with the existing meteorological data acquisition equipment, it has the characteristics of smaller size, lower power consumption, flexible networking, and higher measuring precision. The test results show that the high precision intelligent sensor is stable, reliable and has the functions of high-precision, self-checking, self-calibration, and self-adaption. |
