Special Features

Heartbeat package mechanism

The network heartbeat packet notifies the server that it is in an active state,and it maintains the normal connection with the server by continuously sending the heartbeat packet.
Serial port heartbeat packet notifies the serial device that it is in an active state, and takes the initiative to crawl the sensor data which can not the initiative to push.

Register package mechanism

Server as a TCP Client and UDP Client, when the the link is established, it sends a predetermined registration package as logo automatically.
Registration package data can be MAC address,or custom registration data.
