Pembuatan Alat Monitoring Infus Berbasis NodeMCU ESP8266

The problem of late replacement of infusion mattresses for patients in a medical institution is still common today. It still helps him closely with the nurses' negligence in monitoring the patient's infusion condition. This condition is very dangerous for the patient's health. Therefore the making of infusion monitoring equipment based on NodeMCU esp8266. This tool works by relying on the results of sensor readings that are inserted into the microcontroller which will be processed by NodeMCU. The sensor used in making this system is the sensor module, the sensor reading sensor is the intended emission sensor - in this case, means the drip drops, the sensor will count the number of drops. From the number of drops, it can be used to count the drip infusion. In this study, it can be concluded that the NodeMCU ESP 8266-based infusion monitoring tool using the IR Obstacle sensor component has been successfully made through the functionality test process.

Anesthesia Immutable Registry of Real-time Vital Signs and Waveforms using Blockchain

Healthcare has become one of the most important emerging application areas of blockchain technology.[1] Although the use of a cryptographic ledger within Anesthesia Information Management Systems (AIMS) remains uncertain. The need for a truly immutable anesthesia record is yet to be established, given that the current AIMS database systems have reliable audit capabilities. Adoption of AIMS has followed Roger's 1962 formulation of the theory of diffusion of innovation. Between 2018 and 2020, adoption was expected to be the 84% of U.S. academic anesthesiology departments.[2] Larger anesthesiology groups with large caseloads, urban settings, and government affiliated or academic institutions are more likely to adopt and implement AIMS solutions, due to the substantial amount of financial resources and dedicated staff to support both the implementation and maintenance that are required. As health care dollars become more scarce, this is the most frequently cited constraint in the adoption and implementation of AIMS.[3] We propose the use of a blockchain database for saving all incoming data from multiparametric monitors at the operating theatre. We present a proof of concept of the use of this technology for electronic anesthesia records even in the absence of an AIMS at site. In this paper we shall discuss its plausibility as well as its feasibility. The Electronic medical records (EMR) in AIMS might contain errors and artifacts that may (or may not) have to be dealt with. Making them immutable is a scary concept. The use of the blockchain for saving raw data directly from medical monitoring equipment and devices in the operating theatre has to be further investigated.

Development of the dual-channel frequency meter for measurements with hydrostatic pressure sensor

The paper describes the process and the results of development of the dual-channel frequency meter, which function is to measure the output frequency generated by bottom-mounted pressure sensors. The sensors are actively used to monitor the marine environment. AVR family microcontrollers were used as the computing core of the presented device. This solution allows to obtain far lower power consumption, which is especially important when operating with no industrial power supply system in the coastal zone. As a result, we can deploy a reliable monitoring equipment capable of long-term saving data and if necessary transmit it for further processing. The developed frequency-meter is able to continually record the ambient temperature, atmospheric pressure and dynamically varying output frequency, which depends on hydrostatic pressure (sea level). To obtain more accurate data, we implemented a frequency measure method called reciprocal counter with lower relative error not affected by value of the output frequency. A laboratory experiment has been conducted, which confirms the suitability of the developed frequency meter for field-oriented conditions.

IMPLEMENTATION OF ZONE PRINCIPLE IN THE CONTROL SYSTEM OF REGULATION AND MONITORING EQUIPMENT OF SPACECRAFT ONBOARD NETWORK

Описывается применение принципа зонного регулирования при разработке системы управления аппаратуры регулирования и контроля бортовой сети космического аппарата. Приведены краткие описания аппаратуры регулирования и контроля и входящих в её состав модулей. Приведены функциональная схема регулирования аппаратуры регулирования и контроля и график совместной работы её модулей с разбиением на зоны. Рассмотрена система управления аппаратурой регулирования и контроля. Приведены структурные схемы формирования управляющего воздействия для всех регуляторов аппаратуры регулирования и контроля. Реализация принципа зонного регулирования достигается тем, что вся область возможного изменения сигнала управления разбита на зоны работы, при этом каждому типу модулей выделена своя зона работы. Такой подход, в зависимости от баланса мощности "потребитель - источники", обеспечивает автоматическое подключение требуемых регуляторов. Данный принцип обеспечивает непрерывное изменение сигнала управления в зависимости от энергобаланса системы и параметрических возмущений. Полученную систему можно рассматривать как квазилинейную, что позволяет использовать известные линейные методы синтеза и анализа системы управления, при этом настройка контуров регулирования с заданными показателями качества осуществляется раздельно для каждого типа модулей аппаратуры регулирования и контроля The article describes the application of the zone regulation principle in the development of control system for the regulation and monitoring equipment of the spacecraft's onboard network. We present brief descriptions of the regulation and monitoring equipment and its constituent modules. We show regulation functional diagram of the regulation and monitoring equipment and collaboration of its modules graph with the division into zones. We describe the control system for the regulation and monitoring equipment. We present structural diagrams of the formation of a control action for all regulators of the regulation and monitoring equipment. Zone regulation principle implementation is achieved by the fact that the entire area of possible changes in the control signal is divided into zones of operation. Each type of module has its own zone of operation. This approach provides automatic connection of the required regulators depending on the power balance of the "consumer - sources". This principle provides a continuous change in the control signal depending on the energy balance of the system and parametric disturbances. The system can be considered as quasilinear, which makes it possible to use well-known linear methods of synthesis and analysis of control system. We carried out control loops customization with determined quality indicators separately for each type of the regulation and monitoring equipment modules.

Multi-functional coal mine safety system: visualisation of events (mining processes) form the miner's workplace

The paper reviews the use of mobile video monitoring equipment in coal mines. The most common option is the use of stationary video cameras with real-time video streaming to the mine dispatcher's control monitor via cables. Despite all the benefits of the information obtained, this method has certain limitations due to the specific features of the mine atmosphere, i.e. high humidity and dust levels, as well as the impossibility to organize video monitoring over the entire length of the mine workings. Therefore, mobile video monitoring equipment, both portable and vehicle-based, is efficient supplement to the stationary video cameras. The portable devices include smart phones and the battery-powered head lights with an integrated video camera, which have recently become very popular. In both cases, an important consideration, in addition to the actual video capturing, is the issue of transmitting video data to the top level, i.e. to the mine dispatcher's control panel. The following options are possible: connection to the mine wireless network hotspots via radio channel, reading the information in the lamp rooms when leaving the mine and real-time broadcasting from the mine to the top level. The assumption is made that in order to implement the fastest (and the most efficient) way that works without delays between capturing and transmitting of video data to the daylight surface, such as the latter of the options above, a communications infrastructure based on wireless and cable networks needs to be deployed in the mine workings. The required infrastructure is present in a number of systems designed to locate miners inside the mine workings as part of a multifunctional security system, which enables continuous radio communication of individual devices with infrastructure nodes and, therefore, real-time video data transmission.

Volcano observatories and monitoring activities in Guatemala

The tectonic and volcanic environment in Guatemala is large and complex. Three major tectonic plates constantly interacting with each other, and a volcanic arc that extends from east to west in the southern part of the country, demand special attention in terms of monitoring and scientific studies. The Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH) is the institute in charge of executing these actions at the national and civil level.In recent years, INSIVUMEH has formed a volcanology team consisting of multi-disciplinary personnel that conducts the main volcanological monitoring and research activities. These activities include: seismic and acoustic signal analysis, evaluation and analysis of the volcanic hazards, installation and maintenance of monitoring equipment, and the socialization and dissemination of volcanic knowledge. Of all the volcanic structures in Guatemala, three volcanoes (Fuego, Pacaya, and Santiaguito) are in constant eruption and require all of the available resources (economic and human). These volcanoes present a wide range of volcanic hazards (regarding type and magnitude) that make daily monitoring a great challenge. One of the greatest goals achieved by the volcanology team has been the recent development of a Relative Threat Ranking of Guatemala Volcanoes, taking into account different parameters that allow improved planning in the future, both in monitoring and research. El ambiente tectónico y volcánico de Guatemala es extenso y complejo. Tres grandes placas tectónicas, que interactúan constantemente entre sí, y un arco volcánico, que se extiende de este a oeste en la parte sur del país, exigen especial atención en términos de monitoreo y estudios científicos. El Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH) es el instituto encargado de ejecutar estas acciones a nivel nacional y civil. En los últimos años, INSIVUMEH ha formado un equipo de vulcanología conformado por personal multidisciplinario que realiza las principales actividades de seguimiento e investigación vulcanológica. Estas actividades incluyen: análisis de señales sísmicas y acústicas, evaluación y análisis de peligros volcánicos, instalación y mantenimiento de equipos de monitoreo, y socialización y difusión del conocimiento volcánico. De todas las estructuras volcánicas de Guatemala, tres volcanes (Fuego, Pacaya y Santiaguito) están en constante erupción y requieren todos los recursos disponibles (económicos y humanos). Estos volcanes presentan una amplia gama de peligros volcánicos (en cuanto a tipo y magnitud), haciendo que el monitoreo diario sea un gran desafío. Uno de los mayores logros del equipo de vulcanología ha sido el desarrollo reciente de un Ranking de Peligrosidad Relativa de los Volcanes de Guatemala, tomando en cuenta diferentes parámetros que permitan una mejor planificación en el futuro, tanto en el monitoreo como en la investigación.

Detection for Dangerous Goods Vehicles in Expressway Service Station Based on Surveillance Videos

To improve the safety capabilities of expressway service stations, this study proposes a method for detecting dangerous goods vehicles based on surveillance videos. The information collection devices used in this method are the surveillance cameras that already exist in service stations, which allows for the automatic detection and position recognition of dangerous goods vehicles without changing the installation of the monitoring equipment. The process of this method is as follows. First, we draw an aerial view image of the service station to use as the background model. Then, we use inverse perspective mapping to process each surveillance video and stitch these videos with the background model to build an aerial view surveillance model of the service station. Next, we use a convolutional neural network to detect dangerous goods vehicles from the original images. Finally, we mark the detection result in the aerial view surveillance model and then use that model to monitor the service station in real time. Experiments show that our aerial view surveillance model can achieve the real-time detection of dangerous goods vehicles in the main areas of the service station, thereby effectively reducing the workload of the monitoring personnel.

An environmental monitoring data sharing scheme based on attribute encryption in cloud-fog computing

Environmental monitoring plays a vital role in environmental protection, especially for the management and conservation of natural resources. However, environmental monitoring data is usually difficult to resist malicious attacks because it is transmitted in an open and insecure channel. In our paper, a new data sharing scheme is proposed by using attribute-based encryption, identity-based signature and cloud computing technology to meet the requirements of confidentiality, integrity, verifiability, and unforgerability of environmental monitoring data. The monitoring equipment encrypts the monitored environmental data and uploads it to the environmental cloud server. Then, monitoring users can request access to the environmental cloud server. If the monitoring user meets the access policy, the plaintext is finally obtained through the fog node decryption. Our proposal mainly uses attribute-based encryption technology to realize the privacy protection and fine-grained access control of monitoring data. The integrity and unforgeability of the monitoring data are ensured by the digital signature. In addition, outsourcing computing technology saves the computing overhead of monitoring equipment and monitoring users. The security analysis illustrates that our proposal can achieve security purposes. Finally, the performance of our proposal and related schemes is evaluated from the aspects of communication overhead and computing overhead. The results indicate that our proposal is secure and efficient in environmental monitoring.
