针对传统建筑能耗监测系统存在采集单元功耗高和布线复杂的问题,设计了一种低功耗的无线监测系统。所设计的监测系统包括采集单元、集中器、监测中心和通信网络四部分。其中:采集单元主要由计量电路和BLE(Bluetooth low energy,低功耗蓝牙)通信电路组成,其通过计量电路采集用电设备的能耗数据,并通过BLE通信电路将处理好的能耗数据发送至集中器;集中器主要由BLE通信电路和Wi-Fi通信电路组成,其通过BLE通信电路接收采集单元计量的能耗数据并进行整合、处理,然后通过Wi-Fi通信电路将能耗数据转发至监测中心;监测中心采用B/S(browser/server,浏览器/服务器)架构进行设计,其通过监测界面显示能耗数据并将数据保存在数据库中。所设计的监测系统通过采用BLE和Wi-Fi的通信方式降低了采集单元的运行功耗和布线复杂度,并延长了通信距离;基于B/S架构设计的监测中心可实现跨平台运行,提高了系统的灵活性。测试结果表明,所设计的监测系统的计量偏差率低于5%,通信成功率高于98%,且能够及时监测用电设备的耗能状况,具有较高的实用价值。 相似文献

A proof-of-concept design of a patient monitoring solution for intensive care unit environments has been presented. It is end-to-end standard-based, using ISO/IEEE 11073 (X73) in the bedside environment and EN13606 to communicate the information to an electronic healthcare record (EHR) server. At the bedside end, the system is a plug-and-play sensor network communicating with a gateway that collects medical information and sends the data to a monitoring server. The monitoring server transforms this information into an EN13606 extract to be stored on the EHR server. The system has been implemented to comply with the last X73 and EN13606 available versions and tested in a laboratory environment to demonstrate the feasibility of an end-to-end standard-based solution. 相似文献

Water is one of the basic resources for human survival. Water pollution
monitoring and protection have been becoming a major problem for many countries all over the world. Most traditional water quality monitoring systems, however, generally focus only on water quality data collection, ignoring data analysis
and data mining. In addition, some dirty data and data loss may occur due to
power failures or transmission failures, further affecting data analysis and its
application. In order to meet these needs, by using Internet of things, cloud computing, and big data technologies, we designed and implemented a water quality
monitoring data intelligent service platform in C# and PHP language. The platform includes monitoring point addition, monitoring point map labeling, monitoring
data uploading, monitoring data processing, early warning of exceeding the standard
of monitoring indicators, and other functions modules. Using this platform, we can
realize the automatic collection of water quality monitoring data, data cleaning, data
analysis, intelligent early warning and early warning information push, and other
functions. For better security and convenience, we deployed the system in the Tencent Cloud and tested it. The testing results showed that the data analysis platform
could run well and will provide decision support for water resource protection. 相似文献

As competition for world markets becomes more intense and as greater demands are placed on human and natural resources, manufacturers face a formidable challenge — to produce cost competitive products of the highest possible quality. Nowadays the quality control (quality assurance) department can spend incredibly large amounts of time just collecting the test data they need in order to do their job. Collating and analysing the data is similarly very demanding in terms of how much human time can be expended. Simplification and automation of the tasks of data collection, collation and analysis is possible with a quality control information system. A microprocessor can form the basis of a quality control information system if application to only a very small area of a manufacturing operation is desired. However, far greater benefits can be derived if a real-time minicomputer is used instead of a microprocessor. This is because quality control data can then be collected across the entire factory floor. Statistical quality control techniques can subsequently be applied to examine the effect of process conditions in some part of the factor on product malquality exhibited in any other part of the factory. ‘What-if’ type analyses can also be conducted factory wide. A quality control information system should be capable of (a) identifying the product quality problems (b) determining the causes of these product quality problems (c) helping to eliminate the causes (d) monitoring the altered process. These system functions enable the quality control department to progress from a ‘fix-the-product’ mode to a ‘fix-the-process’ mode and thereby concentrate on making the product right in the first place, by achieving better control of the manufacturing process. Application software packages are now available which have been purpose-designed for quality control information systems. One such example is the Quality Decision Management (QDM) software package from Hewlett-Packard, which runs on an industrial HP 1000 real-time minicomputer. On the data entry side a quality control information system should be capable of manual input from menu-driven terminals and bar-code wands. Automatic input of test data is also vitally important. This enables such devices as analysers, test instruments, data acquisition units. ATE and other computers to be interfaced to gather test data with no manual intervention. All collected data should be held in a database. The QDM database can be searched to generate a wide range of reports in tabular or colour graphic form, the latter include histograms, scattergrams, control charts (X-bar, sigma), P-charts and Pareto diagrams. The reports enable crucial quality control decisions to be taken. Quality control information systems can be linked to higher level production control computers to form a computer integrated manufacturing (CIM) network. Free movement of data around a CIM network offers enormous flexibility and efficiency in the overall manufacturing process, together with considerable savings in manpower. Costs incurred in the creation of a quality control information system can be easily won back by virtue of the significant savings that such a system brings about. 相似文献
