(III) core technology
Relying on the high attention and continuous investment in technology research and development, the issuer has formed an independent core technology system around switches, routers and wireless products after years of research, exploration and practice, as follows:
Serial number core technology description patent technology corresponding to the application product
External main of switches, wireless routing and other products
All interfaces are network interfaces, so the equipment is lightning resistant
The protection ability of lightning strike and ESD depends on the interface
Protection. Due to the poor network port surge of the chip itself
The mold protection ability is weak, so the protection of the mesh port
The protection ability of network port has become an important factor of heavy switch, overvoltage, reverse connection and power failure protection 1 technology to determine the reliability of equipment. Router and protection circuit (patent application No.: the company adopts low-cost network port protection circuit: wireless product 201721730135.9)
By adding varistors and TVs, and
The improvement of PCB layout and wiring
Improvement of surge common mode, differential mode and ESD protection capability
Rise to above 6kV, greatly reducing the network port
Failure rate of.
Compared with ordinary switches, the main 1. The main difference with protective circuit is high-power power supply and DC power supply through non-standard Poe power supply port of Ethernet. System without transformer (patent application No.: isolation, protection of PSE chip and power supply 201710082631.6)
Very important, mainly lightning surge and 2. A power failure protection circuit ESD; (patent application No.: the company adopts pressure sensitive, fuse and TVs tube group 201720408100.7)
2 Poe and its combined circuit and controlled Poe exchange in PCB wiring mode 3. A unmanaged Poe protection technology system can make the POE network port protection capacity reach more than 4KV for the adjustment of power supply power of machine switch; Method (patent application No.: technical iteration, early Poe power supply protocol 802.3 201811052175.1 *)
AF & at, maximum power supply 4. Protocol IEEE802 3BT 15.4W & 30W, the power of power receiving equipment is increased to fully support the demand of 90W power for WiFi 6 and high-power coverage, and Poe electrical equipment (patent application No.: technology added 802.3bt, maximum support 60W 202022787832.6 *) is powered.
The product is repeatedly powered on and off for testing. Through the independent opening of the switch, 1. A control system for automatic technology development of network 3 that is easy to plug in and out, the product serial port printing router, loop back fixture and its preparation technology information are monitored, Method of repeatedly powering on and off the product to test the wireless product (patent application No.: Test and verify the power on and off of the product; 201810677396.1)
Serial number core technology description patent technology corresponding to the application product
Automatic test fixture and script of network interface index, 2 The adjustable power network is subject to the fast electric circuit and equipment that complete the interface index of multi port equipment (patent test; application No.: automatic test software for wireless R & D index, 201710640584.2) It can complete the one key 3 of single or all indicators and a test function of dual power input; Automatic switching circuit (patent production automation research, completed product line test application No.: try one-stop test function. 201810459589. X *)) 4 Device for automatic light sensing test of LED (patent application No.: 201811557503.3 *) 5 Router test fixture (patent application No.: 201910128392.2 *) Switch test device and method (patent application No.: 201910028554.5 *) Switch test fixture (patent application No.: 201910027858. X *)
