990 Security – Security warning system

990 Security is a system that guarantees safety and warnings in case of SOS. With just one press of the button, it will simultaneously send SOS alerts to registered security units. Security units will dispatch forces, update their status and capture the address when there is SOS. You will get accurate and fastest help / rescue.

When using the 990 Security system, you and those around you will be fully protected by the system – intelligent security equipment.

We use IoT (Internet of things) technology that allows devices in the system to communicate with each other without the need for human participation and unify the digital and physical worlds. They are connected and shared data by various methods, namely LTE, Ethernet, Wifi and Zigbee.

4. Websocket: how to communicate and work between the device and the server to complete the device integration

Connection process:

  • The device first sends a start packet to connect to the server
  • After successfully connecting to the server, the device will send a Ping packet to maintain the connection
  • The packets of nodes (sos button, siren …) will be sent when the node has an event (ping, test, alarm …)

Packet format:

  • Packet start connection (start)
  • Connection Maintain Packet (Ping)
  • Information packet list wifi routers used for Geolocation
  • Gateway information packet
  • The management gateway’s node list information package
  • Node event packet (Siren)
  • The node’s event packet (sos button)
  • Confirmation packet (confirm)
  • Package installed from the server
  • Package confirms successful installation

After connecting:

  • After connecting to the server successfully, it will immediately send the start packet to notify the connection to the server, followed by either the maintenance packets (ping) or the data node (data node).
  • The connected ip / port will be stored in the gateway and changed by texting to the gateway (Enable alarm mode, turn off alarm mode, duration of alarm, operation of each sensor, mode works whole device, update ip server)
