Method for improving precision of quartz type dynamic automobile scale

Abstract

A method for improving the precision of a quartz-type dynamic truck scale, the invention relates to the technical field of electrical automation; it improves the quartz-type dynamic truck scale through the data read by a weighing indicator, a charge amplifier, a track detector, a quartz load cell, and a temperature sensor. Vehicle scale accuracy; the quartz weighing sensor is connected with the charge amplifier, and the charge amplifier is connected with the weighing indicator; the track detector and the temperature sensor are all connected with the weighing indicator; the weighing indicator is connected with the weighing indicator Charge amplifier connection; improve the measurement accuracy of the quartz-type dynamic truck scale, the highest measurement accuracy of the weighing instrument system can reach ±1.0%, at the same time, improve the confidence, reliability and stability of the quartz-type dynamic truck scale; Charge disputes caused by balance errors.

Description

technical field [0001] The invention relates to the technical field of electric automation, in particular to a method for improving the precision of a quartz dynamic truck scale. Background technique [0002] The quartz load cell bears the gravity of the tires of the driving vehicle and generates a charge signal. The signal is amplified, sorted and converted into a voltage signal, and then the total weight of the vehicle is calculated after A / D conversion. In the process of dynamic weighing, the inconsistency of the accuracy and sensitivity distribution of the quartz load cell itself, the non-uniform straight-line driving of the measured vehicle (that is, irregular driving, such as acceleration or deceleration passing, inclined, S-shaped driving, etc.) through weighing Changes in measuring area and ambient temperature are the main objective factors that cause the maximum measurement error of the quartz truck weighing system to be large (greater than ±1.5%, even exceeding ±5%...

In the process of dynamic weighing, the inconsistency of the accuracy and sensitivity distribution of the quartz load cell itself, the non-uniform straight-line driving of the measured vehicle (that is, irregular driving, such as acceleration or deceleration passing, inclined, S-shaped driving, etc.) through weighing Changes in measuring area and ambient temperature are the main objective factors that cause the maximum measurement error of the quartz truck scale system to be large (greater than ±1.5%, or even exceeding ±5%)

Under the original technical conditions, even if the high-quality imported quartz weighing sensor is used, the maximum measurement error of the weighing instrument system cannot be effectively controlled within ±2.0%
