In order to resolve automatic measurement, automatic monitoring and control of heat energy, a new type IC Card heat energy meter with automatic monitoring and control is designed. Software and hardware design of the heat instrument is introduced. Solutions of these problems are proposed throng analysis of engineering design problems. Lower power consumption and high precision requirements of heat measurement are met by collecting lower consumption components and intelligence design manners. Automatic measurement, monitoring and control functions are realized through gathering heat parameters of end-users on time, and analysis, comparing on the gathered data and data from standard meter by microcomputer. Preliminary tests show that the heat energy meter has functions of high precision, lower power consumption, strong intelligence and can achieve automatic Measurement, automatic monitoring and automatic control.

Abstract In the last decade, the interest in software-defined ultra-wideband (UWB) and tunable radio frequency (RF) apparatuses with low size, weight, and power consumption (SWaP), has grown dramatically, pushed by the new 6G vision where, RF equipment shall enable a large number of fundamental applications as UWB communications, robot localization mapping and control and high precision radars, all of them contributing in revolutionizing our life style. Unfortunately, the coexistence of ultra-wideband and software-defined operation, tunability and low SWaP represents a big issue in the current RF technologies. In this article, to the best of our knowledge, the first example of a complete tunable software-defined RF transmitter with low footprint (i.e. on photonic chip) is presented exceeding the state-of-the-art for the extremely large tunability range of 0.5-50 GHz without any parallelization of narrower-band components and with fast tuning (<200micros). This first implementation, represents a breakthrough in microwave photonics.

Synchronization Protocol

ZigBee technology is more and more used in complex and bad industrial monitoring and control environment. At the same time, ZigBee nodes are usually powered by batteries, so prolonging the working time and reducing the power consumption of the nodes is very important. If the wireless nodes can turn into sleep mode in spare time of communication, it will further reduce the node power consumption. But in sleep period, the node can't communication with other node, we need to synchronous awaken and dormancy, so precise time synchronization for wireless sensor network application is particularly important. This paper will apply FTSP algorithm in the ZigBee network and realize the network time synchronization. At the same time, it doesn't increase power consumption of the network.

Seasonal Factor

The article proposes a method for predicting the daily energy consumption level for every day of a whole year, taking into account the season-al factor, based on only twelve actual power consumption data by the months of the year. Then a mathematical model is developed for moni-toring and controlling the level of electricity consumption on a daily basis, taking into account the seasonal factor. The model is consistent with a common model for the length of daylight (in hours). In addition, on the basis of this model, a method of monitoring and diagnostics of electricity consumption is presented, which will allow users to monitor the level of power consumption and be timely notified of any deviations from the theoretical level. Finally, this method gives rise to the operational principle for a proposed device, a smart energy meter, for detecting suspicious deviations from the theoretical level. The device will help timely detect over-consumption (or under-consumption) of electricity in order to take preventive measures. The proposed method consists of the following steps: (1) choice of a function to model the level of electricity consumption (theoretical calculated level), (2) choice of a tubular control neighborhood of the graph of the model function, (3) choice of a criterion on when the smart energy meter should notify the user of an unexpected deviation from the theoretical level in the case of exit from the tubular control neighborhood.
