1.1 Project background
Over the years, with the continuous acceleration of the process of scientific and technological development, my country’s informatization construction has made considerable progress, and the military, judicial, public security and other state departments have begun to build warehouse systems. In this regard, Chuangyi Technology has a relatively complete set of plans for the management of the information system of the Ministry of Public Security’s equipment warehouse. The main characteristics of public equipment warehouse management are: fewer people and more materials, and diverse materials. Therefore, materials need to be managed in different ways according to specific conditions and management requirements.
Therefore, we must prioritize the establishment of a management system for the combat readiness warehouse, and use the application of the system as a starting point to gradually realize the intelligentization of the military’s logistics support.
Traditional warehouse management generally relies on a non-automated paper document-based system to record and track incoming and outgoing goods. The internal management of the warehouse is completely implemented manually, so the efficiency of warehouse management is extremely low. In this regard, we use a warehouse intelligent management system based on ZIGBEE wireless radio frequency technology, which can enhance the accuracy and speed of warehouse operations, and reduce the illegal entry and exit, misplacement, and theft caused by inadequate management of the entire combat equipment in and out of the warehouse. And the loss of inventory, shipment errors, etc., and minimize storage costs to ensure the safety of war preparations.
2 Demand analysis
Traditional warehouse management generally relies on a non-automated paper document-based system to record and track incoming and outgoing goods. The internal management of the warehouse is completely implemented manually. Therefore, the efficiency of warehouse management is extremely low, and the warehouse that can be managed The scale is also very small.
With the popularization of computer applications, most of the enterprise warehouse management data materials have begun to use computer data systems for management, but the data is still collected and statistically organized by first recording on paper and then manually inputting it into the computer. This not only causes a lot of waste of human resources, but also due to human factors, the data entry speed is slow and the accuracy rate is low.
With the continuous development of the Ministry of Public Security’s intelligence, the number of material types and machines managed by public installations and warehouses is increasing, and the frequency of in and out of the warehouse has increased sharply. Warehouse management operations have also become very complex and diversified. The traditional manual warehouse operation mode and data collection method It has been difficult to meet the rapid and accurate requirements of warehouse management, which has seriously affected the efficiency of the Ministry of Public Security.
At the same time, in recent years, there have been many problems in material transportation and vehicle management, such as few records, missing records, and private vehicles. More and more people have not only caused a serious loss of materials due to this omission, but also formed work habits in the Ministry of Public Security that are extremely unfavorable to long-term development due to inadequate management measures, which have seriously affected the development of intelligence and modernization.
At present, ZIGBEE technology is bringing a huge change to warehouse management, to identify the incomparable advantages of barcodes such as long distance, fast, hard to damage, and large capacity, simplify the complicated work process, and effectively improve the efficiency and transparency of the supply chain. China·Chuangyi Xingsheng Technology Development Co., Ltd. is based on the Internet of Things intelligent combat readiness warehouse management system that introduces ZIGBEE technology into the existing warehouse management, and performs warehouse arrival inspection, warehousing, outgoing, allocation, shifting, and inventory. Automated data collection is carried out on the data of each operation link such as inventory, to ensure the speed and accuracy of data input in each link of warehouse management, to ensure that the real data of the inventory is grasped in time and accurately, and the inventory is maintained and controlled reasonably. Through scientific coding, it is also convenient to manage the batch and shelf life of items. Using the system’s location management function, you can also grasp the current location of all inventory materials in a timely manner, which is conducive to improving the efficiency of warehouse management. At the same time, it will better serve the combat readiness warehouse and provide a favorable guarantee for the accurate and error-free work of the army’s logistics department, equipment department, and training department.
3 System principle
The warehouse management system is mainly used for the automated management of the entry and exit of warehousing supplies, and consists of ZIGBEE electronic tags installed on the outer boxes of war preparations, wireless routing nodes, coordinators, handheld readers, management center network management equipment and management software. When the war preparation materials carrying the ZIGBEE electronic tags pass through the radio frequency sensing area set by the warehouse, the system uses the ZIGBEE electronic tags to realize automatic inventory, pick-up and rapid inventory and material monitoring in the warehouse. Through scientific coding, it is also convenient to dynamically manage the batches and origins of items. Using the system’s location management function, it is possible to grasp the current location of all inventory war preparations in time, which is beneficial to ensure the safety of war preparations and improve the efficiency of warehouse management.

Hybrid App (hybrid mobile application) refers to an app that lies between web-app and native-app. It has both “the advantage of a good user interaction experience with Native App” and “the advantage of cross-platform development of Web App”.
Hybrid App is developed using web language and programming language at the same time, and is distributed through the application store to distinguish mobile operating systems. Users need to install and use mobile applications. The overall characteristics are closer to Native App but are quite different from Web App. Just because webpage language coding is used at the same time, the development cost and difficulty are much smaller than that of Native App. Therefore, Hybrid App has all the advantages of Native App, as well as the low-cost advantage of using HTML5 cross-platform development for Web App.
