Concrete pump truck discharge capacity metering method and metering system based on vibration signal treatment

The invention discloses a concrete pump truck discharge capacity metering system based on the vibration signal treatment. The system comprises a data storage module, a signal-collecting module, a system control module, a concrete pumping metering module and a discharge capacity standardization module. The invention further discloses a concrete pump truck discharge capacity metering method based on the vibration signal treatment, which comprises the steps as follows: firstly, collecting work-state data and utilizing extreme value increment DFA for data analysis so as to form a pump truck discharge capacity database; secondly, collecting vibration data in real time, utilizing the extreme value increment DFA for data analysis on the collected data, and performing discharge standardization on the real-time data; thirdly, calculating the total discharge capacity of the pump truck according to the standard discharge capacity and pumping time. According to the invention, the method can effectively filter away various uncorrelated tendencies in a non-stable time sequence, and greatly reduce the difficulty of discharge capacity metering, and the external metering method can improve the metering reliability greatly, and can solve the problems that the metering efficiency and the metering precision are insufficient in the prior art effectively.
