附 錄 附錄 A 外文資料 Data Collection At present,the management of China’s colleges and universities’ apartments are developing toward standardization and market development,accidents have occurred in electricity,while some colleges and universities have installed apartment energy metering control system,however,these systems monitor the prevalence of low level,billing accuracy is low,electricitysharing,the work number of the drawbacks of low , improving the Energy Measurement monitoring device has bee more urgent. The issue of student hostels in colleges and universities to monitor energy metering system to study, design the student hostels in colleges and universities of the electricity data collector apartment. Data acquisition, also known as data acquisition, is the use of a device that collect data from outside the system and enter into an interface within the s acquisition technology is widely cited in the various as camera, microphone, all data collection is being collected has been converted to electrical signals of various physical quantities such as temperature, water level, wind speed, pressure, etc., can be analog, it can be e collection generally means that a certain time interval (called the sampling period) to repeat the same point of data data collected are mostly instantaneous value, but also a feature within a certain period of time value. Accurate data measurement is the basis for data measurement method of contact and noncontact detection elements of which method and ponents are measured object does not affect the status and measurement environment as a precondition to ensure the accuracy of the y broad meaning of data collection, including continuous physical hold the collection across the puteraided mapping, surveying and mapping, design, digital graphics or image data acquisition process may also be called, this time to be collected is the g
