i. program overview<\/h2>

China's current manufacturing industry, although the volume is huge, but the management is sloppy, not fine enough; although the government advocates \"smart factory\", \"Industry 4.0\" for many years, but the factory's level of intelligence is still very low, can not be compared with Germany, Japan and other manufacturing powerhouses. In addition to some large enterprises, such as Foxconn, Gree, in actively trying to factory robots, automated management, most of the small and medium-sized enterprises are still stuck in the comparative advantage of relying on labor cost advantage, the supply chain is relatively perfect survival. With the rise of China's new generation after 95, 00, the new generation has not satisfied with low pay + overtime pay system, coupled with the manufacturing industry back to the southeast industry and other lower-cost countries, China's manufacturing industry is facing the plight of the more aggravated. How to change the management problems of China's manufacturing factories and realize the transformation of manufacturing factories into \"smart factories\" and \"intelligent factories\"? This is a common problem in China's manufacturing industry.<\/p>

II. Factories encountering difficulties<\/h2>

Due to the large number of people in the production workshop and its dispersion, it is impossible to control the production line staff in real time, and it is difficult to assess the on-duty situation quickly and to manage the situation of employees' crosstalk and off-duty; at present, the traditional manual supervision method is adopted, which is unable to effectively supervise and statistic the on-duty data. In order to better promote the intelligent construction and realize the fine management of the factory, the introduction of activeZigBee<\/a>(used form a nominal expression)positioning technology<\/a>In order to obtain the working hours invested by the employees in each position in the manufacturing process, the production capacity can be analyzed according to the production report at a later stage, thus optimizing the production structure and improving the production efficiency.<\/p>

III. Programmatic structure<\/h2>

3.1 System architecture<\/h3>

Factory personnel positioning system mainly consists of 1: personnel carrying positioning tags; 2: receiving information positioning base station; 3: transmission and power supply network cable and DC power supply and switch; 4: positioning location server; 5: server computer and positioning software 5 parts. The positioning tag is responsible for sending the positioning pulse signal, the positioning base station is responsible for receiving the pulse signal and sending the information back to the location server through the network cable and switch, and the location server processes the positioning data and reports it to the positioning software on the server computer to display the positioning data in real time.<\/p>

3.3 Network Topology<\/h3>

433MHz wireless network reader FB-RWN02 can be expanded through the wireless network interface 16 wireless readers, including themselves (the device itself is also an independent reader) a wireless network can have up to 17 location base stations. Wireless readers will read the tag information reported to the network reader, and then the network reader will wireless network range of all the tag information reported to the location server, the location server to the data synthesis algorithm to derive the specific location of the tag.<\/p>

The location server has two Ethernet interfaces ETH0\/ETH1. If the location base station is deployed to the user network, it is sufficient to use one interface ETH0, or you can build a new network for the location base station, which requires two Ethernet interfaces. It is recommended to build a new network for the positioning base station so that the operation of the positioning system will not be affected by the user's network and will be more stable.<\/p>
