GIVING 5G PATROL ROBOTS THE ADVANTAGE: ADVANTECH’S MIC-770 ASSISTS IN CHINA’S FIGHT AGAINST CORONAVIRUS


s a part of its eff ort to contain the spread of COVID-19, China is using 5G patrol robots, developed by the Guangzhou Gosuncn Robot Company, which use Advantech technology to monitor mask wearing and body temperatures in public places. The smart city/IoT products and services provider upgraded its 5G-powered police patrol robot with new capabilities to assist fi rst-line police offi cers in conducting disease prevention inspections during this vital time. Because the manual

data requires systems to run at much faster transfer speeds and this requires higher frequencies and faster transition times for oscillators. HCSL offers a constant current characteristic delivering a less “noisy” solution compared with static logic devices. This technology offers a high impedance output with fast switching times and, by fitting a 10 to 30Ω series resistor, any overshoot or ringing is reduced. This is a major benefit for mixed, low voltage signal processing, such as can be seen in optical networking.


If a high temperature, or the absence of a mask is detected, the robots will send an alert to the relevant authorities. All data can be transmitted to a centralised control centre, which is then followed by a decisive, real-time, situational response. Moreover, although these robots are self-driving machines, they can also be controlled remotely, thereby saving manpower by reducing patrolling responsibilities and preventing cross-infection. It’s no surprise then that these next-generation 5G patrol robots have already been spotted in operation within airports and shopping malls in the cities of Guangzhou, Shanghai, Xi’an, and Guiyang. Due to the high traffi c of data that has to be processed by these robots, Gosuncn has adopted the industrial


The current consumption of HCSL generally lies between LVDS and PECL formats but offers faster speeds.


This type of steering logic offers a constant current output; with a 15mA current source the current is “steered” between the true and complimentary outputs. Current steering techniques have also been used in bipolar technology with the sole objective of speeding up logic gates. It should also be noted that HCSL outputs require 50Ω termination as shown below in figure 2.


Software for the sick


The latest Euroquartz oscillators offer frequencies up to 250MHz with enhanced jitter and phase noise performance as can be seen in figure 3.

As developments in 5G applications continue and demand for faster data transmission increases, so oscillator performance characteristics will be further enhanced. There is little doubt that the latest HCSL oscillator designs are set to become one of the key
