Remote warehouse environment state monitoring and positioning system

Abstract

The invention designs a remote warehouse environment state monitoring and positioning system and belongs to the application field of ZigBee network technology. The system includes a client, a server, and an acquisition control device. The client is in communication connection with the server through the Ethernet. The server receives a monitoring request of the client, is in communication connection with acquisition control device through a ZigBee monitoring network, realizes real-time acquisition, storage, and automatic control of the warehouse environment state quantity and precise positioning of a data acquisition node, and gives an alarm in the case that the warehouse environment state quantity exceeds a limit. Further, according to the data returned from the server, the client displays the warehouse environment state quantity in the form of a chart in real time on a JSP interface. The remote warehouse environment state monitoring and positioning system can acquire, display, store and automatically control the warehouse environment state quantity anytime and anywhere, and can locate the data acquisition node with an average error less than 0.3 meters in real time, and has low system cost, low power consumption and simple operation.

Description

technical field [0001] The invention relates to the application field of Zigbee network technology, in particular to a remote monitoring and positioning system for warehouse environment status. Background technique [0002] In traditional industrial control and environmental monitoring applications, fieldbus technology is the communication carrier for collecting data and transmitting control commands. Fieldbus technology is mainly wired connection methods, such as CAN bus, RS-485, etc. The ZigBee technology based on the IEEE 802.15.4 standard is a short-distance, low-complexity, low-power, low-speed, low-cost two-way wireless communication technology. With ZigBee technology, you can quickly build multiple nodes and support multiple network topologies. , reliable and safe wireless network, ZigBee network technology is suitable for industrial control and environmental monitoring fields. [0003] In the traditional monitoring system of warehouse environment status, the communi...

Problems solved by technology

[0004] The traditional warehouse environment status monitoring system mainly controls the warehouse environment status manually, which is neither intelligent nor real-time; when the environmental status collected by a certain data collection node is abnormal, most of the traditional warehouse The monitoring system only has the function of alarming and prompting, but does not have the function of locating nodes. It cannot quickly obtain the exact position of corresponding nodes. It has been processed in time. Some systems with positioning functions only realize node positioning by querying the pre-stored coordinates in the database. This method is feasible for fixed nodes, but not for mobile nodes; the traditional warehouse environment status system can only monitor the warehouse environment status through the local control machine, does not support remote operation, and cannot monitor anytime and anywhere
