Affected by New Coronary Pneumonia, Hong Kong's economy has been hit hard. Some start-up bosses were inspired by the boss's phrase "Why there are no orders, the power consumption is still high" during the 2008 financial tsunami, and they designed energy-saving software to start a business with friends. In this epidemic situation, he seized the opportunity and tailored a 24-hour production environment monitoring system for the mask factory, which could save power for the factory and increase the production efficiency of the mask factory.
He bluntly said that job hunting will be more difficult under the epidemic, but he believes that "it is organic when there is a danger", and he calls on the fresh graduates to maintain their confidence and interest, keep trying, and insist on developing in their favorite industries.
Yang Jiaqiang, the chief executive officer of the "Citylink Technology", an information technology company in the Science Park, recently worked with local mask manufacturers to use cloud and Internet of Things and other information technology technologies to tailor a production environment monitoring system for the plant.

Although the epidemic in Hong Kong has shown signs of easing recently, masks are still one of the necessities for citizens to go out. Yang Jiaqiang, a graduate of the Information Technology Department of the Hong Kong Institute of Vocational Education (IVE), founded the technology company "Citylink Technology" about ten years ago. The company focuses on finding energy-saving solutions for enterprises through IoT technology. Yang Jiaqiang, the company's chief executive, took advantage of this special feature to seize the opportunity during the "epidemic" market, and cooperate with local mask manufacturers under the recommendation of a friend. It took three days last month to customize and install a production environment for the plant. The monitoring system uses cloud, Internet of Things and other technologies to monitor the production status of the dust-free workshop of the mouth plant for 24 hours, providing solutions that can save energy and improve production efficiency.
He explained that the system is mainly divided into three parts, including the installation of sensors in the dust-free workshop of the mask factory, the monitoring of the operation status of automated production machines and the CCTV security system.
Sensors to monitor the air in the dust-free workshop of the mask factory
The sensor can detect the concentration, temperature and relative humidity of PM2.5 in indoor suspended particles, and cooperate with the Internet of Things technology to control equipment such as air-conditioning and fresh air fans to ensure that the air quality in the plant meets the standards. Yang Jiaqiang said that the supply of masks is tight and urgent. Many factories rush to make masks to extend working hours. Therefore, the sensors will measure the carbon dioxide concentration, light and noise in the factory, and try to provide workers with a high-quality working environment and improve work efficiency. The system's smart meter will monitor the power consumption of the machine, record and analyze power data such as voltage and current changes, and pay attention to the operation of the machine.
Yang Jiaqiang explained that predicting the possible problems of the machine will help repair and reduce the possibility of delaying production. "If a machine's power consumption is very unstable, timely and frequent, it means that it may have abnormal conditions, malfunctions or need to be repaired. The team found that the production performance of the machine with a complete appearance did not meet expectations, and finally found that the source was the manufacturer installing the wrong parts; before the mask factory conducted certification testing, the team identified that there were more dust particles in individual locations, reminding the factory to promptly remedy , The final factory obtained the clean room certification.
24 hours security monitoring will issue a warning
For security, the team has connected CCTV to the cloud. The factory management can monitor the operation of the plant with a mobile phone application 24 hours a day. In the event of smoke in the plant or air quality problems, the system will issue a warning prompt. Yang Jiaqiang said that in the future, he hopes to improve the software interface, accumulate more data in the long run, and use artificial intelligence (AI) to provide timely advice to customers to make the service smoother.
Encouraging graduates to be loyal to their interests and believing that they are
entering the graduation month, Yang Jiaqiang encourages fresh graduates to be loyal to their interests and maintain their confidence, to join a passionate industry. He recalled that he had loved computers in his childhood, so he studied information technology at IVE before going to university to study. Although he faced a financial tsunami in 2008 after graduating from college, he was still determined to join the technology industry, and the boss said, "Why are there no orders and the power consumption is still high?" Inspired his idea of starting a business. He and his friends worked together to design a set of smart meters and power consumption management software. By analyzing the electricity consumption of the company in the past year, they provided energy-saving and emission-reduction solutions to help customers save electricity expenses and promote environmental protection. He founded the company about two years later.
He bluntly understood that it would be more difficult to find a job under the epidemic, but there will still be opportunities to call on graduates to maintain confidence and interest: "If there is a danger, there is an opportunity." "Don't give up on yourself."
