ZOOMLION's data acquisition instrument - building a "black box" of engineering machinery
Recently, the R & D center of ZOOMLION Concrete Machinery Co., Ltd. has launched a vehicle data acquisition system for products of the branch company, which greatly improves the accuracy of all kinds of R & D data and has become another weapon for technology development of branch company.
Because of the bad general conditions and complex and changeable working conditions of the construction machinery, it is very important to collect the construction data. It not only can directly reflect the working conditions of the equipment, but also is of great significance to the statistics of the construction law of the equipment and the research on the improvement of the performance of the equipment. At the same time, the research of massive information extraction relying on large data platform has also become the trend of industry development.
The GPS platform for the ZOOMLION concrete pump is one of the data collection platforms. GPS is the key component of data communication between controller and platform in the electric control system of concrete pump truck. On the one hand, it connects with the company platform through mobile network, on the other hand, it connects with the controller on pump truck through CAN bus. However, due to the constraints of communication traffic and cost, the previous GPS platform can only collect rough statistics and short time actual operation data. Although these data can understand the construction status, it needs a lot of manpower to analyze and sort out, and it is difficult to fully understand the long-term construction rule of construction machinery. With the adjustment of the company's strategy, a more convenient and efficient tool is needed to break through the plight of the construction of large data collection.
The Technology Department of ZOOMLION concrete machinery company has been deeply researched and developed. This year, the data acquisition instrument for engineering machinery and equipment finally came into being. The instrument for the specific advantage of customers is as follows: one can realize the remote control of the pump, the problems can be found and resolved, avoid downtime and unnecessary economic losses; two is the monitoring and handling of the pump is suitable for the poor conditions, unattended environment. The vehicle data acquisition instrument as an efficient information platform for large data collection tools, not only can last for a long time continuous storage construction data of the target device, can also meet the requirement of key data accuracy, and can achieve unattended data acquisition, is an important instrument for the ZOOMLION construction machinery technology research and development.
The instrument is compact and flexible. It has been installed on a key pump truck of ZOOMLION. Through experiments, it is found that replacing the memory card can accomplish the rolling collection of millions of lines of massive working data, which greatly improves the data collection efficiency of equipment condition. The collected construction data can help us to calculate the construction rules of different regions and different types of equipment, as the important input data for the research and development of the follow-up products. Relying on the big data platform, we can also feedback the results of construction data analysis to the device terminal for the first time, instruct the machine operator to operate correctly, remind the customer to maintain and maintain, so as to ensure the efficient operation of the equipment and enhance the user experience.
With the help of ZOOMLION big data platform and later technology processing methods, we can not only record the construction rules of the equipment, but also successfully reproduce the details of the specific working conditions. The vehicle data acquisition instrument has become the "black box" of engineering machinery.
