An intelligent measurement system is introduced, which is based on time-triggered embedded system with the characteristics of multitask and multiparameter in the process of measuring parameters. The system is consist of MCU, USB and the time-triggered structure. The predictability makes the system avoid the interrupt loss. The stability and reliability of the system has been improved. The experimental results show that the system not only has the characteristics of flexible measurement control, data transmission, and data storage, but also can analysis the field parameters.

Measure Error

The method of wheel-weight for mine's automatic light rail weight-bridge is put forward. According to some important factors which cause measure error using wheel-weight method, for example, zero drift, speed and gradient, the error compensation algorithms are studied. The software flow charts of these algorithms are given, which have been put into effect in the ARM microprocessor based embedded system. It has been found that these error compensation methods are efficient to improve the accuracy of the measurement system.

Current Characteristics

In order to analyze wide frequency band corona current characteristics of the UHV bundled conductors, a corona current measurement system is developed. The corona current signal is transmitted to the lower computer through the wireless network. And the current signal collected in this way is safe and reliable. The de-noise method with wavelet analysis is introduced and compared with some common used methods. The result of the de-noising analysis of the wide frequency band corona currents of bundled conductors in the corona cage shows that the wavelet analysis method could be used to de-noise high frequency corona current in the corona cage, and the de-noising effect is apparent.
