The Evolution of Concrete Mixer Truck Automation Systems in Modern Construction

Concrete mixing transporter is an essential key equipment in modern construction engineering, and the performance enhancement of concrete mixing transporter is directly related to engineering efficiency and concrete quality. According with the continuous development of science and technology, the application of automation technology in concrete mixing truck is becoming more and more in-depth, and has experienced the evolution from auxiliary function to intelligent autonomous operation process. This paper summarizes the development of automation system of concrete mixing truck at present in modern construction engineering, and analyzes their key technologies evolution.

Exploring automation early on: accessibility use

Within the early stage of the concrete mixing truck automation system development, the main purpose was to reduce the labor intensity of operators as well as enhancing the convenience of the operation. This stage automation is primarily expressed in the auxiliary control of the basic functions of the vehicle. As an example, the electrically or hydraulically powered drum rotation system replaces the previously used manual shaking crank and automates the processes of starting, stopping and speeding up the drum. Therefore, the simple water filling system has begun to be used in some automobile factories, which preset the water amount to eliminate the possibilitiy of manual meter metering error. But the automation of this period is at a low level, and key links such as batching, vehicle loading and unloading are still manual operation, and the level of intelligence is limited.

Intermediate automation development: Use of integrated control and sensor technology

Due to the smooth development of electronic technology and sensor technology, the automation system of concrete mixing truck has entered the intermediate stage of development. The integrated control system has been applied to the automobile, and the independent control unit is integrated into a whole to realize the centralized control and accurate adjustment of the key parameters such as the speed of the mixing cylinder, the amount of water added and the discharge speed. At this stage, sensor technology takes such as; the level sensor must be used to ensure the precise amount of water added, the speed sensor is used to monitor mixing cylinder speed in real time, and the pressure sensor detects the state of hydraulic system, etc. The use of these technologies increases operational precision and consistency, minimizes human mistakes, and serves as a precursor to subsequent increased levels of automation. A few of the higher echelon models are playing with the concept of accessible on-board computers for data logging and simple fault monitoring.

Stage of advanced automation: the improvement in intelligent and autonomous function

In recent years, with the development of information technology, artificial intelligence and Internet of Things technology precipitation height sensor for concrete mixing truck can make the automation system upgrade to a new level. At this stage ingenuity and independence are the defining attributes.

"Intelligent dosing system: Automatically measure the aggregate weight and humidity, concrete parameters, cement, sand, admixture according to the set concrete formula, achieve automatic weighing, accurate dosing, avoid manual add ingredient errors, to ensure concrete mixing ratio accurate.

The monitoring of slump, temperature, uniformity and other indicators of concrete can be realized, and the indicator data can be displayed and recorded through the vehicle system or remote monitoring platform, which can provide strong support for the quality control of concrete. More sophisticated systems can automatically tune mixing parameters based on real-time data feedback processes to optimize the quality of the concrete.

Driving assistance and route optimization: Here above, some new concrete mixing trucks have global Positioning systems (GPS) and electronics maps for route planning and navigation. By integrating auxiliary driving functions like automatic parking and lane keeping with sensors and control systems, driving safety measures can be enhanced and driving efficiency can be improved.

Fault Diagnosis And Fault Prediction: Through the vehicle communication system, the vehicle's operating status and fault information can be sent to the remote monitoring platform in real time, so that the manager inspects and manages. There are systems available with initial fault diagnosis function, indicating potential failure risks, and they can assist maintenance personnel in maintenance.

SLO: Towards fully automated trends: Views on AI & collaborative work

In the future, the automation system of concrete mixing trucks will lead to a higher degree of full automation. One significant catalyst will be the adoption of artificial intelligence (AI) technologies.

AI-based intelligent scheduling and optimization: This through the construction of progress analysis, analysis of traffic conditions and other information through AI algorithms, collecting effective information from the scene, to achieve intelligent vehicle scheduling and route optimization, to maximize the vehicle utilization rate and transportation efficiency.

Predictive maintenance and fault self-diagnosis: Analyze vehicle operation data to predict wear trends in critical components, allowing for planned maintenance before unplanned downtime occurs. The fault diagnosis system based on artificial intelligence can more quickly and accurately locate the cause of the fault, and shorten the time of maintenance.

Application of autonomous driving technology: With the maturity of driverless technology, future concrete mixing trucks are expected to achieve a certain degree of autonomous driving, such as autonomous transportation and unloading in closed construction sites, further reducing labor costs and safety risks.

Work with other equipment: By Internet of Things technology, concrete mixing trucks can communicate with, and collaborate with other construction equipment, such as concrete pumps, cranes, etc., to create a more efficient construction process.

Concrete mixing truck automation system had gone through the evolution process stages from auxiliary function to integrated control to intelligent autonomous operation. The advancement of sensing technology, electronic technology and information technology and artificial intelligence has promoted the continuous improvement of automation level. Automated control of the mixing truck can not only improve the working efficiency of the mixing truck and concrete quality, but also reduce the labor strength of the operator and improve the operating safety. With the in-depth application of artificial intelligence and other technologies in the future, the automation level of concrete mixing truck will reach a new level, providing new kinetic energy for the intelligent development of modern construction projects.
