The invention discloses a dynamic monitoring system of grouping welding equipment, which is based on a wireless network in the technical field of automatic detection. The dynamic monitoring system comprises a welding mechanism, an embedded signal acquisition module, a network central node and an on-site server, wherein the embedded signal acquisition module is fixedly arranged in the welding mechanism and is connected with the welding mechanism to collect current and voltage signals in the welding process; the embedded signal acquisition module is connected with the network central node and outputs a welding state by a Zigbee network; the network central node outputs the welding state to the on-site server by a 232 serial port; and the on-site server is connected with an enterprise management computer network through the Ethernet so as to bring convenience for enterprise managers to log in the on-site server to monitor equipment. The invention can be used for simultaneously detecting 1024 equipments, and the detected equipments can move in the network range so as to realize the remote monitoring and the management of the grouping welding equipment and the production process.
