共創智慧監獄

為配合懲教署積極發展智慧監獄系統的計劃，機電署主動為客戶部門尋找和配對創新科技解決方案，自去年年中起開展了三個概念性的試驗計劃，以提升監獄的管理效率及保安水平，當中包括應用多項創新科技(例如人工智能、物聯網、藍牙低功耗技術、機械人等)設計和安裝最先進的系統及器材，以期把香港打造成為更安全的智慧城市。

懲教署對監察系統和保安設備素有嚴格要求，就此，我們因應實際環境，在設計過程中構想多個潛在事故的場景。經過多月的反覆測試及不斷改進產品設計和電腦演算法，囚倉監察系統的發展已初見成效，其中影像分析監察系統主要透過智能閉路電視偵測在囚人士的違規或自殘行為，現已率先於壁屋監獄四個囚倉進行試驗；以及為羅湖懲教所引入智慧手帶以配合物聯網的應用，並安裝維生指標和移動及位置監察系統，協助前線人員監察在囚人士的身體狀況和追蹤其活動位置。

我們除了優化管理硬件之外，亦致力推動工序創新，例如緝毒機械臂系統可取代以人手檢查在囚人士的排泄物是否藏有毒品，該系統現正於荔枝角收押所進行初步測試。

這些新設施的試驗計劃完成後，我們將與懲教署進行成效評估，並會研究把這些創新科技方案推廣至其他懲教院所。

我們樂意與客戶分享用於提升保安的先進科技，如欲查詢詳情，請致電 2808 3384 與高級工程師簡偉光先生聯絡。

Co-creating a Smart Prison with Innovative Technology

In line with the Correctional Services Department’s (CSD) plan to actively develop the smart prison system, the EMSD takes the initiative in sourcing and matching innovative technology solutions for client departments, and commenced three conceptual trial schemes since mid-2018 to enhance the efficiency of prison management and the level of security. These include the design and installation of state-of-the-art systems and equipment through the application of various innovative technologies, such as artificial intelligence, Internet of Things (IoT), bluetooth low-energy consumption technology and robotics, etc., with a view to building Hong Kong into a safer smart city.

The CSD has strict requirements on their monitoring systems and security equipment. In this connection, we have conceived various scenarios of potential incidents in the design process having regard to the actual environment. After several months of repeated testing and continuous improvement to the product design and computer algorithm, we start to see some initial results in the development of the dormitory monitoring system, including the Video Analytic Monitoring System, which mainly detects irregularities or self-harm behaviours of persons in custody through smart closed-circuit televisions and is being tested in four dormitories of Pik Uk Prison; as well as the introduction of smart wristbands at the Lo Wu Correctional Institution (LWCI) to tie in with the application of IoT. The LWCI is also installed with Health Signs Monitoring and Passage Surveillance Systems, which help frontline staff monitor the health conditions of persons in custody and track their locations of movement.

Besides optimising the management hardware, we are also dedicated to promoting process innovation. For example, the Drug-detection Robotic Arm System, which is currently undergoing a preliminary test at the Lai Chi Kok Reception Centre, can replace the manual inspection of drug products in the excreta of persons in custody.

Upon completion of the trial schemes for these new facilities, we will evaluate their effectiveness with the CSD and explore extension of such innovative technology solutions to other correctional institutions.

We are happy to share with clients the advanced technologies used to enhance security. For details, please contact Mr. Raymond Kan, Senior Engineer, at 2808 3384.

Creativity Wins Innovation Awards from
the Hong Kong Institution of Engineers

With a view to enhancing the quality of public services and improving people’s lives, the EMSD applies innovative engineering knowledge to meet the needs of clients and the community, and works with university teams to develop state-of-the-art technologies. In March this year, the Smart Fever Screening System jointly developed by the EMSD and the Hong Kong University of Science and Technology (HKUST) was awarded a grand prize of the Hong Kong Institution of Engineers (HKIE) Innovation Awards for Young Members 2019 (Category I – An Invention). Meanwhile, our NeuroSmart Eyes Air-conditioning Control System also won a merit award in another category (Category II – An Innovative Application of Engineering Theories).

Combining infrared thermal imaging, artificial intelligence and automated operation, the Smart Fever Screening System automatically detects in real time the body temperature profile of people in an area of a given size. It also enables staff to obtain real-time data analysis for tracking febrile suspects, thus enhancing the operation efficiency of the Department of Health for health screening at border control points and minimising obstruction to people flow.

The prototype of the Smart Fever Screening System has been completed and funding from the Innovation and Technology Bureau’s TechConnect (Block Vote) has been secured for trial at selected border control points at a later stage.

The merit award winner, the NeuroSmart Eyes Air-conditioning Control System, is suitable for use at such venues as large exhibition halls with dynamic changes in people flow. With the video analytics technology, the system can collect in real time the data on people flow and adjust the air flow rate according to changes in the crowd density, thus providing a more comfortable environment to the public. Through a display board, the system can also show the level of crowdedness in a specific area. If it reaches a saturation point at a certain exhibition area, visitors can move to other exhibition areas, thus achieving effective control of people traffic. In the long run, it can even enhance energy efficiency of the air-conditioning system.

物聯網應用

物聯網的迅速發展對通訊技術有很高的要求，尤其是用以連接大量物聯網系統的無線通訊技術，需具低用電量、低寬帶、長距離的特性，當中LoRa、Sigfox及NB-IoT三大新興技術已漸趨成熟。為支持建設智慧城市，向客戶提供增值服務，機電署最近建立了實際的試驗環境，就無線物聯網技術的協調、干擾及網絡效能進行測試。

過去三個月，機電署在總部大樓設置以LoRa為標準的無線網絡基礎設備，並裝設不同的感測器以進行測試，當中包括在會議室的在場感測器及溫濕度感測器、在辦公室的光源感測器，以及在停車場的智慧泊車感測器等，藉以測試感測器和電池的性能及數據準確性。我們現正評估試驗結果，並計劃利用這些數據開發智能停車場和會議室預訂系統，預計於今年年中進行測試。

我們亦會與其他客戶部門合作，在沙田區推行利用LoRa無線通訊的先導計劃。我們已於選定地點設置基站，以供日後根據不同應用場景，安裝合適的感測器進行測試。

除LoRa外，機電署會在總部大樓就Sigfox及NB-IoT技術進行進一步測試，比較不同技術的優劣之處，為日後廣泛推展物聯網應用做好準備。

展望未來，我們計劃在不同客戶的場地陸續裝設基站，收集感測器數據，並在總部大樓建立一個由機電署管理的物聯網平台，為客戶提供上述三種技術收集所得的數據，以供作應用程式開發及分析用途。

如客戶有興趣了解或參與物聯網的試驗項目，請致電2808 3593與高級工程師陳賀賢先生聯絡。


Internet of Things Applications

The rapid development of Internet of Things (IoT) requires a high level of communication technologies, in particular wireless communication technologies that are used to connect a vast number of IoT systems and have unique features of low power consumption, low bandwidth and long-distance coverage. Among the emerging technologies, the three major ones, namely LoRa, Sigfox and NB-IoT, have gradually matured. To support the building of a smart city and provide value-added services to clients, the EMSD has recently established a physical testing ground for conducting tests on the co-ordination, interference and network performance of wireless IoT technology.

In the past three months, the EMSD set up a LoRa-based wireless network infrastructure at its headquarters building. Different types of sensors were installed for testing the performance of these sensors and their batteries, as well as validating the accuracy of data collected. They included occupancy sensors and temperature and humidity sensors in conference rooms, light sensors in offices, and smart parking sensors in car parks. The test results are being evaluated. It is planned to utilise the data to develop smart car parks and meeting room reservation systems, which are expected to undergo testing in the middle of this year.

We will also work with other client departments to launch a LoRa-based wireless communication pilot programme in Sha Tin. Base stations have been built at selected locations to facilitate future installation and testing of suitable sensors for different application scenarios.

Besides LoRa, the EMSD will conduct further tests on Sigfox and NB-IoT technologies at the headquarters building so as to compare the strengths and weaknesses of different technologies, and get prepared for the extensive roll-out of IoT applications in the future.

Looking forward, we plan to build base stations at different client venues to collect sensor data. An IoT platform managed by the EMSD will also be established at our headquarters building to provide clients with data collected by the above three technologies for the purposes of application development and analysis.

If clients are interested to know more about or join the IoT trial project, please contact Mr. Steve Chan, Senior Engineer, at 2808 3593.

新科技去除油煙

機電署致力研究並引進新興技術，為客戶提供優質的工程方案。熟食中心的廚房排煙系統和排氣管道容易積聚油脂，導致火警事故。有見及此，我們為客戶引進新排煙系統，於一個月內在試點成功安裝紫外光C及臭氧除油煙設備，經過半年測試，證明安全及成效顯著。我們現正在該中心進行全面安裝，預計於今年第二季完成。

由於熟食中心長時間運作，使用水濂機或靜電除油煙器的傳統方法未能全面防止油脂在排氣管道內迅速積聚。我們為客戶安裝的排煙系統，乃科技的一大突破，通過應用紫外光(短波UV-C)結合臭氧的技術，再配合排氣管道的特別設計，能有效地將油煙內的油分子快速分解。同時，紫外光與臭氧能將油分子化成水、氧氣、二氧化碳和聚合油脂，這些非黏性物質能有效防止油脂積聚在管道內壁上。

我們樂於與客戶分享最新的排煙技術，歡迎致電3757 6027與高級工程師彭國強先生聯絡。

New Technology to Remove Oily Fumes and Grease

The EMSD is committed to developing and introducing emerging technologies, so as to provide quality engineering solutions to clients. The kitchen exhaust system and its ductwork at cooked food centres are prone to grease build-up, resulting in fire incidents. In view of this, a new exhaust system was introduced to the client for the first time, in which ultraviolet-C (UV-C) ozone equipment was successfully installed at a pilot venue within a month. Its operation has been proven to be safe and effective after a half year’s testing. Full-scale installation of the equipment is being conducted at the venue, and is scheduled for completion in the second quarter of the year.

Due to the long operating hours of cooked food centres, the conventional method of using water scrubbers or electrostatic precipitators to treat oily fumes can no longer prevent the rapid build-up of grease inside the exhaust ductwork. The new exhaust system we installed for the client is a technology breakthrough, which combines the technologies of UV light (short wave UV-C) and ozone. Coupled with the special design of the exhaust ductwork, the grease molecules of oily fumes can be effectively decomposed. Moreover, the UV light and ozone can further break down the grease molecules into water, oxygen, carbon dioxide and polymerised grease. These non-sticky substances can effectively prevent accumulation of grease on the inner walls of the exhaust ductwork.

We are happy to share this new exhaust system with clients. Please contact
Mr. Sunny Pang, Senior Engineer, at 3757 6027 for details.

加強電動車充電設施

今年，我們與環境保護署和土木工程拓展署合作，首次在大嶼山梅窩的政府戶外公共停車場安裝中速充電器，預計於本年年中完成安裝，屆時可為九輛電動車同時充電。相比傳統的標準充電器，中速充電器可大幅減少充電時間近六成。據最新公布的2019至20年度財政預算案所載，政府將撥款1.2億元，擴大政府停車場提供的電動車公共充電網絡，預計到2022年會增逾1 000個公共充電器，令總數增至1 700個。

此外，為加強電動車充電配套設施的功能及效用，機電署會在總部大樓推行先導計劃，率先為充電設施加裝多項智能系統及配件，預計於今年完成安裝。這些系統及配件包括：智能計量系統，用以量度不同停車場的充電設施使用量，從而有效分配資源；佔用傳感器系統，讓車主可上網或利用應用程式預先知道停車場充電設施的佔用率；電子顯示板，用以顯示停車場内可供使用的尚餘充電器數量；電源用量管理系統，供調節繁忙時段的充電速度。這些系統將為未來的電動車充電器安裝計劃提供數據分析，以加強停車場整體充電系統的遠程監控管理。

客戶如對電動車輛充電設施感興趣，歡迎致電3757 6134與我們的高級工程師鄧偉豪先生聯絡。



Enhancing Electric Vehicle Charging Facilities

This year, we co-operate with the Environmental Protection Department and the Civil Engineering and Development Department to install medium chargers for the first time at the outdoor public car park in Mui Wo, Lantau Island, which is targeted to be completed by the middle of this year. Upon completion of the installation, nine electric vehicles (EVs) can be charged there at the same time. Comparing to the conventional standard chargers, the medium chargers can significantly reduce the charging time by nearly 60%. As mentioned in the most recently announced 2019-20 Budget, the Government will allocate $120 million to extend the public EV charging networks at government car parks. Over 1 000 additional public chargers are expected to be in place by 2022, bringing the total number of chargers to
1 700.

Moreover, in order to strengthen the functions and effectiveness of the ancillary facilities for charging EVs, a pilot project will be implemented at the EMSD Headquarters to install additional smart systems and accessories on the charging facilities, which is scheduled for completion within this year. These systems and accessories include: the smart metering system which measures the usage of charging facilities at various car parks for better allocation of resources; the occupancy sensor system which enables drivers to have access to the occupancy rate of charging facilities at car parks online or via mobile applications in advance; the electronic display board which shows the number of remaining chargers available for use in a car park; the power consumption management system which regulates the charging speed during peak hours. All these systems provide data analysis for our future EV charger installation plan, thus enhancing the remote monitoring management of the overall EV charging system at car parks.

If clients are interested to know more about the EV charging facilities, please call our Senior Engineer, Mr. Ronald Tang, at 3757 6134.
