Design, Development, and Fabrication of an Intravenous Infusion Monitoring Device 静脉输液监测装置的设计、开发和制造
Natapol Phetsuk, S. Umchid
For the gravity-driven intravenous infusion, the nurse normally observes and counts the drips in the drip chamber and determines the drop factor on the IV administration set to the drops per minute for an infusion by gravity. This method is quite complicated and may not be accurate. Therefore, the objectives of this study were to design, develop, and fabricate the infusion monitoring device using wireless data transmission. The developed system uses an infrared sensor to detect IV fluid droplets. The microcontroller ESP32 was used for processing data before displaying it on the TFT screen and sending wireless data with the wireless transmission on a wifi network to display on the internet browser at the nurse station in order to monitor the information from a distance and to reduce the continuous on-site monitoring. Our developed system was tested to verify the measuring flow rate and delivered volume in comparison with the infusion device analyzer in the range of flow rate between 20 and 200 milliliters per hour with different lighting conditions. The results indicate that the device can real-time monitor the infusion process and present accurate infusion information. In addition, the alarm signal will be activated when the infusion stops, rate too fast, and complete. This developed system can provide advantages in many aspects such as convenient deployment, flexible use, and reliability.
对于重力驱动的静脉输注,护士通常观察和计数点滴室中的点滴,并确定静脉给药的点滴因子,设置为重力输注的每分钟滴数。这种方法相当复杂,可能不准确。因此,本研究的目的是设计、开发和制造采用无线数据传输的输液监测装置。开发的系统使用红外传感器来检测静脉滴液。利用ESP32单片机对数据进行处理后显示在TFT屏幕上,通过wifi网络将无线传输的数据发送到护士站的互联网浏览器上显示,实现远程监控,减少现场连续监控。我们开发的系统在不同的光照条件下,与输液器分析仪在20 - 200毫升/小时的流量范围内进行了测试,验证了测量流量和输送量。实验结果表明,该装置能够实时监控输液过程,提供准确的输液信息。此外,当输液停止,速率过快,完成时,报警信号将被激活。该系统具有部署方便、使用灵活、可靠性高等优点。

An Optical Fiber Monitoring and Alert System for A Passive Optical Network Based on IoT 基于物联网的无源光网络光纤监控报警系统
Pubet Sangmahamad, Tanaporn Pechrkool, Puttiporn Thiamsinsangwon
The one important in a passive optical network (PON) for high-speed communication is fault detection and fault alert due to the troubles of passive optical fiber or passive optical devices. Any failure of optical devices in the optical link can influence to a huge amount of data loss in the optical network. However, deployment of fault detection and alert devices or systems is extremely limited due to the financial implications and reliability of the devices or systems. Thus, this work proposes a design and implementation of a cost-effective way for detection when an optical link has a fault in a PON. Also, real-time wirelessly alert to a responsible person. This monitoring technique is based on bidirectional light-wave communication with single-core single-mode optical fiber and internet of things (IoT) technology. Which consists of 2 sub-systems namely the transmitter of the optical fiber monitoring system (OFMS-Tx) is located at the optical network unit (ONU). And the receiver of the fiber monitoring system (OFMS-Rx) is located at the optical line terminal (OLT). Both parts operating with microcontrollers, which the OFMS-Tx microcontroller uses for generating a monitoring signal that depends on situations such as normal operation situation or power outage situation. The OFMS-Rx microcontroller act as a monitoring signal decoder for the decision of the OFMS-Tx and optical link situations. Also, OFMS-Rx real-time alerts to responsible person when fault occurring, such as optical link fail or ONU power outage. From experimental results show that the proposed system is automatically working for real-time optical fiber link detection and immediately alert to the responsible person within 11 seconds when a fault occurs. Also, the proposed system could transmit a monitoring signal in the network over a fiber distance of 70 km.
在高速通信的无源光网络(PON)中,故障检测和无源光纤或无源光器件故障报警是一个重要的问题。光链路中任何光设备的故障都会导致光网络中大量数据的丢失。然而,由于设备或系统的财务影响和可靠性,故障检测和警报设备或系统的部署非常有限。因此,这项工作提出了一种设计和实现一种经济有效的方法来检测PON中的光链路故障。此外,实时无线警报负责的人。该监测技术基于单芯单模光纤双向光波通信和物联网技术。它由两个子系统组成,即光纤监控系统的发射机(OFMS-Tx)位于光网络单元(ONU)。光纤监控系统的接收端(OFMS-Rx)位于光纤线路终端(OLT)。这两个部分都与微控制器一起操作,OFMS-Tx微控制器用于根据正常运行情况或停电情况等情况产生监控信号。OFMS-Rx微控制器作为OFMS-Tx和光链路情况的监测信号解码器。此外,OFMS-Rx在发生故障时,如光链路故障或ONU停电时,可实时向责任人发出警报。实验结果表明,该系统能够自动进行实时光纤链路检测,并在故障发生11秒内立即向责任人发出警报。此外,所提出的系统可以在70公里的光纤距离上传输网络中的监测信号。

W. Songserm, Jakkrit Latthawanichphan, T. Wuttipornpun, Watcharapan Sukkerd
This paper proposes an improvement of instance generator for scheduling problems called i-IGSP. There are three significant improvements from the existing IGSP. The first feature is the main contribution of this paper, which is the integration of an assembly operation option with parallel machines to all types of multi-level and multi-operation production shops, known as flow shop and job shop. These shops have been found in many modern industries and scheduling researches at the present. The second feature provides the choice of due time scenarios. The third enhancement makes the output text files more consistent and for all production shops. Based on the improvements, i-IGSP has become one of the most completed instance generators for scheduling problems than the other instance generators published in the literature. Researchers can use it to not only to evaluate their algorithms and generate benchmark problems but also to save time and cost of data collection from real industries.

Design of Approximate 2DOF Digital Control for Widely Dimming LCL-T Resonant LED Driver 宽调光LCL-T谐振LED驱动器的近2自由度数字控制设计
S. Mangkalajan, Kamon Jirasereeamongkul, K. Higuchi
In this paper, the robust digital control method, Approximate 2 Degree Of Freedom (A2DOF) digital control method, is used for Light Emitting Diode (LED) current control. Since the dynamic range of light emitting diode current as a dimming function from 100% to 2% dimming are analog control, but it is not possible to make it very low current or is called "extremely dark". The reason is that the voltage and current characteristics of light emitting diodes are high non-linear, and the internal resistance changes greatly as the current decreases. The resonant circuit use LCL-T network circuit. Therefore, the digital control is appropriate. A robust digital controller derived from this control method is mounted on microcontroller, and experiments show that the lower limit of light emitting diode current can be expanded or less than 1%. The experimental results shown that the method has lower limit of light emitting diode current or extremely dark.
本文采用鲁棒数字控制方法——近似2自由度(A2DOF)数字控制方法对发光二极管(LED)进行电流控制。由于发光二极管的动态范围以电流为调光函数,从100%到2%的调光都是模拟控制的,但不可能使电流非常低或称为“极暗”。其原因是发光二极管的电压和电流特性是高度非线性的,内阻随着电流的减小变化很大。谐振电路采用LCL-T网络电路。因此,数字控制是合适的。在单片机上安装了基于该控制方法的鲁棒数字控制器,实验表明,该控制方法可使发光二极管电流下限提高或小于1%。实验结果表明,该方法具有发光二极管电流下限或极暗的特点。

A Comparison of MPPT Solar Charge Controller techniques: A Case for Charging Rate of Battery MPPT太阳能充电控制器技术的比较:以电池充电速率为例
Chantima Lapsongphon, Supaporn Nualyai
In this research, two MPPT solar charge controller techniques have been measured; Perturb & Observe (P&O) and Incremental Conductance (IC) techniques. The comparison of MPPT solar charge controller techniques has been analyzed for estimating the battery charging rate and system efficiency. To carry out this experiment, the MPPT solar charge controller techniques were applied to the buck converter circuits for extracting maximum power from the PV panel into the battery. Moreover, the MPPT solar charge controller techniques were also tested in a stand-alone PV system with an 80 W PV panel and lead-acid battery which had a capacity of 20 Ah. However, the experimental results indicated that the charging rate of the IC technique can be calculated at 0.83 V/hr, while the other technique is equal to 0.65 V/hr. Furthermore, the total efficiency of the stand-alone PV system with the IC technique is around 95%. This implies that this technique has extremely efficient.

A Genetic Algorithm for Split Delivery Open Vehicle Routing Problem with Physical Workload Consideration 考虑物理工作负荷的分割配送开放车辆路径问题的遗传算法
Tarit Rattanamanee
Last-mile delivery is an important part of a logistics activity in the city. Usually, delivery workers are required to manually unload goods at customer locations. These manual tasks induce physiological fatigue in the workers and increase delivery time. This paper discusses a genetic algorithm (GA) approach to the open vehicle routing problem with split delivery (SDOVRP), where manual unloading is addressed. The workers are pre-assigned to vehicle and split delivery is allowed. Its objective is to minimize the total cost of total fixed cost of vehicles and delivery workers and total transportation cost. For safety, the total physical workload imposed on each worker must not exceed the daily limit. Since an optimization approach cannot find the optimal solution within reasonable computation time especially when solving large size problem. A GA with heuristic for pre-determine split delivery is developed to solve the problem. The computational experiment results show that the GA approach is efficient and can obtain near-optimal SDOVRP solutions.
最后一英里配送是城市物流活动的重要组成部分。通常,送货员需要在客户所在地手动卸货。这些体力劳动会引起工人的生理疲劳,并增加交货时间。本文讨论了一种遗传算法(GA)来解决带有分离配送的开放式车辆路径问题(SDOVRP),其中解决了人工卸载问题。工人被预先分配到车辆上,并且允许分批交货。其目标是尽量减少车辆和运送工人的总固定成本和总运输成本的总成本。为了安全起见,每个工人的总体力负荷不得超过每日限额。由于优化方法无法在合理的计算时间内找到最优解,特别是在求解大型问题时。为了解决这一问题,提出了一种启发式的遗传算法。计算实验结果表明,该方法是有效的,可以得到接近最优的SDOVRP解。

Usually, delivery workers are required to manually unload goods at customer locations. These manual tasks induce physiological fatigue in the workers and increase delivery time. This paper discusses a genetic algorithm (GA) approach to the open vehicle routing problem with split delivery (SDOVRP), where manual unloading is addressed. The workers are pre-assigned to vehicle and split delivery is allowed. Its objective is to minimize the total cost of total fixed cost of vehicles and delivery workers and total transportation cost. For safety, the total physical workload imposed on each worker must not exceed the daily limit. Since an optimization approach cannot find the optimal solution within reasonable computation time especially when solving large size problem. A GA with heuristic for pre-determine split delivery is developed to solve the problem. The computational experiment results show that the GA approach is efficient and can obtain near-optimal SDOVRP solutions.","PeriodicalId":422981,"journal":{"name":"2021 Research, Invention, and Innovation Congress: Innovation Electricals and Electronics (RI2C)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114324552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chutirut Prasongmanee, P. Wannapiroon, P. Nilsook
The 20-Year National Strategy (2017-2036) defines the country vision that "Thailand is stable, prosperous, sustainable, is a developed country". On the issue of human resource development and empowerment to become highly skilled Thai people in the digital age. Human development is a very important factor in raising the country to become a developed country in the future. Especially government personnel who have to develop to become professional personnel with new competencies, able to support changes in the development context and operating in accordance with the national development direction, raising the new competencies to be comparable at the international level. To change the culture of work and create good values of government personnel to perform government service based on the public sector of the people for the people, as well as developing leadership with high capacities. The development of a supervisor, a personnel in the government sector who serves to inform and introduce educational knowledge to teachers in schools or colleges is essential. Supervisor is one of the important government personnel who serves to inform and introduce educational knowledge to teachers in schools or colleges in promoting and supporting education management in order to drive policies from the Ministry of Education to schools and colleges. The development of the supervisor to be a person with digital competence in bringing technology and digital tools to be integrated into performance according to the specified competencies to drive towards Thailand 4.0. The situation in the spread of infectious virus, corona 2019 (COVID-19), which is the driving force for adaptation and bringing new technology and educational model innovation to change Thai education. Supervisors are considered as essential personnel to increase digital competencies in their operations. The digital supervisor's competencies consist of 3 areas: digital knowledge, digital skills, and self-reliant traits in digital individuals.
《20年国家战略(2017-2036)》确定了“泰国是一个稳定、繁荣、可持续发展的发达国家”的国家愿景。关于人力资源开发和赋权的问题,以成为数字时代的高技能泰国人。人的发展是使一个国家在未来成为发达国家的一个非常重要的因素。特别是政府人员,他们必须发展成为具有新能力的专业人员,能够支持发展背景的变化,并根据国家发展方向运作,提高新的能力,以便在国际层面上进行比较。改变工作文化,创造良好的政府人员价值观,以公共部门为人民服务,为人民服务,培养高能力的领导能力。培养一名主管,即政府部门的一名人员,向中小学或大学的教师提供教育知识的信息和介绍,是必不可少的。督导人员是在促进和支持教育管理,推动教育部政策向学校落实的过程中,向学校教师通报和介绍教育知识的重要政府人员之一。将主管培养为具有数字能力的人,根据指定的能力将技术和数字工具整合到绩效中,以推动泰国4.0。传染性病毒2019冠状病毒(COVID-19)的传播情况是适应和带来新技术和教育模式创新的动力,以改变泰国的教育。主管被认为是提高其运营中数字能力的关键人员。数字主管的能力包括三个方面:数字知识、数字技能和数字个体的自力更生特征。
