Abstract

The invention discloses a mobile port crane data acquisition system based on GPRS, which comprises a field intelligent unit and a remote PC end, wherein the field intelligent unit comprises a PLC controller, a serial port, a field data acquisition end and a GPRS communication module; the remote PC end comprises a data monitoring module and a fault diagnosis module; the PLC controller acquires real-time parameters of the crane; the parameters are transmitted to the field data acquisition end through the serial port; the field data acquisition end carries out compression, processing and interface conversion on the real-time parameters of the crane; the parameters are then transmitted to the remote PC end through the GPRS communication module; the data monitoring module carries out decompression and processing on the received data to obtain the real-time parameters of the crane; and the fault diagnosis module diagnoses whether a fault happens according to the real-time parameters, and a diagnosis result is returned to the field intelligent unit. The data acquisition system of the invention can carry out remote and real-time acquisition, monitoring and fault diagnosis on the working state data of the mobile port crane, the transmission is stable, and the configurability is high.

Description

Technical field

[0001] The invention relates to crane technology, in particular to a GPRS-based mobile port crane data acquisition system. Background technique

[0002] During the lifting operation of the crane, it is necessary to collect the key data of the crane, such as the rotation speed, temperature, oil pressure and speed of the generator, in order to detect and deal with machine failures and improper control in time, so as to avoid damage to the crane and cause engineering accidents Case. With the further development of "One Belt One Road", higher requirements are put forward for the transportation efficiency, safety performance and real-time status monitoring of mobile port cranes.

[0003] At this stage, the data monitoring system of mobile port cranes can only perform local monitoring of cranes, which increases the cost of manual monitoring to a certain extent. In addition, the working environment of the port is relatively harsh and the facilities are not complete, whic...
