International general (VNA) flatness specification   1. UK TR34 2003 Edition In recent years, some concepts are easily heard in the industry, such as “super flat floor”, “one kind of floor” or “two types of floor”. It is necessary to point out that these concepts are derived from the levelness classification of the Orienteering floor in the Third Edition (2003) of the technical report of the Concrete Association of Concrete Association of the United Kingdom (TR-34). TR-34 third version of the flat level of the VNA narrow

1. Battery technology The earliest shuttle car is a semi-automatic control mode, and its structure and system are simple. Battery technology is one of the key technologies that affect its application. The working time that can be met by each full charge becomes a bottleneck for shuttle car. While high performance batteries are expensive, the application of shuttle car is very limited. With the continuous improvement of the battery performance and the decline in the price after the production, the shuttle car has been widely used.  

Electronic control system   1. System overview   The electronic control system mainly completes the control task of the conveying equipment in the automation logistics system. The upper and the upper part of the logistics system is connected to the upper computer and the dispatching computer, and the material delivery instructions are received. The device motor is connected down to realize the driving and conveying material detection and identification of the underlying equipment, and complete the process control and material tracking of material transportation. In addition, it

Computer information system   1. System architecture   Computer information system is an online material management system centered on material storage, supply services, linking production, centralized management and information tracking. It integrates logistics support management, material management and warehousing management. It is the information center of management and scheduling. The logistics information system is responsible for the online material process management. By sending the scheduling instructions to the scheduling system, the material storage management and pre-production reserve are guaranteed. It can be connected to the management system

1 Shortcut   First of all, the Internet has broken through the limitation of space distance. The networks of different countries and regions have been integrated into one another, so that the whole world is closely linked, so that things far away can be processed just as before. Secondly, it breaks through the constraints of time, so that people’s information transmission and economic exchanges can be carried out in a very short time span.   Now it’s the time of the speed economy. The logistics activities of

Overall planning of logistics   1. Project overall planning and equipment selection   (1) ASRS   A dense storage and three-dimensional warehouse is used. This area consists of three layers, each layer around the end of a shuttle will orbit, and ASRS divided into left and right three reservoirs. Each layer of each reservoir were designed 20 roadway, about 1 in each tunnel section, the middle area of each roadway 18 section, the total number is 1200.   The selection of dense storage stereoscopic warehouse is relatively
