With the development of the Internet and advances in communication technology, cross-platform, componentized GIS (Geographic Information System) and GPS (Global Positioning System) technologies are gradually matured, and GIS/GPS-based applications will construct competitive transparent logistics enterprises. . The application of GIS to logistics analysis mainly refers to the use of GIS's powerful geographic data functions to improve logistics analysis technology. The application of GPS in the field of logistics can monitor the location of moving targets such as vehicles in real time, and issue real-time scheduling commands to mobile targets according to road traffic conditions. The effective combination of GIS, GPS and wireless communication technology, coupled with vehicle route model, shortest path model, network logistics model, distribution set model and facility positioning model, can build a powerful logistics information system to make logistics real-time. And the cost is optimal.

According to the survey report of the China Storage Association, the no-load rate of vehicle operation in China is about 45%. One of the important reasons for this situation is that the logistics company can not accurately know the specific location of the running vehicle, and can not keep in touch with the driver anytime and anywhere, and can not organize the supply and flexible distribution. At the same time, the driver can only determine the route based on personal experience, and sometimes can not find the best path, not only delay the opportunity but also increase the operating cost. In addition, the actual customers can not understand the situation of the goods distribution process in time, and can not coordinate with the logistics enterprises.
The advantages of GIS/GPS in logistics enterprise applications are mainly reflected in the following aspects:
1. The application of GIS/GPS will definitely improve the informationization degree of logistics enterprises, and digitize the daily operation of enterprises, including the logistics equipment owned by enterprises or any goods of customers, which can be described by precise figures, which not only improve the operation of enterprises. Efficiency, while enhancing corporate image, can win more customers.
2. The combination of GIS/GPS and wireless communication makes the transportation equipment flowing in different places transparent and controllable. Combined with the support of the decision-making model library of the logistics enterprise, according to the actual storage situation of the logistics enterprise, and the real-time road information obtained by GPS, the optimal logistics path can be calculated, the navigation equipment can be navigated, the running time can be reduced, and the running cost can be reduced. GPS and GIS technology can be used for real-time positioning, tracking, alarming, communication, etc., which can meet the needs of mastering basic vehicle information and remotely managing vehicles, effectively avoiding the no-load phenomenon of vehicles, and customers can also use Internet technology. Know the details of your cargo during transportation. For example, vehicles collecting milk in grassland pastures have failed on the way. Traditional logistics companies often cannot find faulty vehicles in time and the original milk of the whole vehicle is broken, causing heavy losses. GIS/GPS can easily solve this problem. In addition, human factors are everywhere, and GIS/GPS can effectively monitor driver behavior.
3. Through the coordination of logistics operations, promote the development of collaborative commerce, and let logistics enterprises transform into the role of the fourth party logistics. Since the logistics company can obtain the specific location and cargo information of each vehicle in real time, the logistics enterprise can use the system concept to operate the business of the enterprise and reduce the no-load rate. The transformation of this function, if the logistics company serves a certain supply chain, can play the role of the fourth party logistics. Through wireless communication and GIS/GPS, logistics enterprises can accurately obtain the information of transportation vehicles, and then let the internal and customer access through the Internet, thus making the operation and business of the whole enterprise transparent and laying the foundation for collaborative business. The physical architecture of the information platform of the logistics enterprise is shown in the figure. However, the integration of geographic information system (GIS), satellite positioning system (GPS), wireless communication (WAP) and Internet technology (Web), applied to the field of logistics and supply chain management information technology, is not fully mature in China. However, it is believed that with the attention of people and the advancement of technology, GIS, GPS, WAP and Web technologies will be combined to jointly depict transparent logistics enterprises, reduce logistics black holes, enhance the competitiveness of domestic logistics enterprises, and open the logistics market in the near future.

Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
