王甲,阮颐,宋文博

摘要:随着互联网技术和电子技术的发展,近年来,网络结算已经变成人们生活的一种方式,人们可以通过接入网络的设备,如手机、电脑等进行各种购物和结算。中国国家电网公司对电表的网络化改造项目已经使得网上查询电量和缴纳电费成为可能。但是,同样作为涉及民生中最重要的组成部分之一的用水情况,其查询和结算在大多数城市还依赖人工抄读。这是因为水表是一个无源设备,其电子化设计难度要远大于智能电表,所以如何将水表计量的数据数字化是水表设计中需要解决的核心问题。在诸多技术中,摄像直读技术作为将水表计量电子化的一个重要手段,目前已经得到大规模的推广和应用。但实际使用中,由于受环境或者光线的影响,其识别的准确率始终还存在问题,因此如何提高摄像直读识别的准确率,已成为研究摄像直读技术的一个重要课题。

摘要:电能、自来水和燃气已经成为支撑居民生活的重要能源保障,针对这三种能源的计量仪表是智能电表、水表和燃气表。随着电子技术和互联网技术的发展,目前智能电表和水表基本已经完成了新的计量方式的改型设计,它们的精度和适应性都有较大提升。而燃气表的计量方式还基本沿袭着传统的膜式燃气表的计量方式,仅仅在字轮部分增加了传感器进行采样。这种设计思路虽然简便,但众所周知,膜式燃气表基础计量是需要依靠橡胶皮膜的作为测量介质的,而橡胶皮膜的物理性质受环境影响较大,且随着日常的使用会产生不可逆的老化,因此膜式燃气表的计量误差和适应性均很难得到提升。因此,研究结合了电子控制部分和硬质缸体来取代橡胶皮膜作为计量介质的新式燃气表,有望改善原有膜式燃气表计量方式的不足,计量精度和适应性都可实现大幅提升。

Abstract: Electricity, water and gas has become the most important energy guarantee in daily life, and the corresponding metering devices are smart meter, water meter and gas meter. With the development of electronic technology and internet-based life, smart meter and water meter has basically completed the transformation of new metering way, which get big promotion in accuracy and adaption. Meanwhile gas meter still use the traditional way of diaphragm gas meter, with additional sensor sampling of character wheel. Simple as the method is, it is well-known that basic metering of diaphragm gas meter depends on rubber diaphragm as metering medium. The physical property of rubber diaphragm is affected greatly by environment, and will deteriorate with daily use, so it is hard to get a promotion in metering error and adaption of diaphragm gas meter. Therefore, research of electronic control part and rigid cylinder to replace the rubber diaphragm as metering medium will improve the disadvantage of traditional diaphragm gas meter, and promote the metering accuracy and adaption greatly.

一种能适应不同黏滞系数的流量计的设计
孙小勇,王甲,阮颐
摘要:通常某一种流量计设计总是针对某一种特定的液体体积进行计量的,例如水表是用来计量自来水体积的,汽油表是计量汽油体积的,柴油表是用来计量柴油体积的。除了分类使用的要求之外,在技术层面的原因在于不同液体的黏滞系数不同,所以用水表计量油的体积显然是不准确的。但在某些特殊的场合,需要便捷的测量出多种不同液体的体积时,传统的流量计是无能为力的。基于此,先通过电泵给液体加速,待克服液体本身的黏滞性后,通过计量流量和标定的体积比较确认,然后再用这个速度给液体进行加速计量,即可实现用一种流量计适应不同黏滞系数的液体体积的计量。

Design of Flow Meter Adaptable of Different Viscosity Coefficients
SUN Xiaoyong, WANG Jia, RUAN Yi

Abstract: Usually design of a certain flow meter is aimed at certain liquid volume metering, for example, water meter is used for water volume metering, gasoline gauge for gasoline volume, and diesel fuel flow meter for diesel fuel. Apart from the demand of uses for different kinds, technically metering oil volume is inaccurate with water meter because viscosity coefficients vary from different liquids. However, on certain occasions, when it is needed to measure different kinds of liquids conveniently, traditional flue meter is incapable. Accelerate the liquid with electric pump first, when the viscosity of liquid is overcome, meter the flow and compare it with calibrated volume, finally accelerate the liquid with the velocity, thus metering the volume with one flow meter adaptable of different viscosity coefficients is realized.

A Circuit of Dual Modulus Prescaler
WEN Jianxin, YANG Hailing

Abstract: A circuit of Dual Modulus Prescaler is presented. The main characteristic is that the high-frequency signal of the VCO is processed by the pre-dividing circuit without reducing the resolution. The optimized half-rate dual-mode divider structure is used to effectively improve the reference frequency of the PLL. With the bandwidth of PLL, it can effectively control the high frequency noise of ring VCO and achieve better phase noise performance. Using this high-speed fractional frequency divider, a PLL with main frequency of 3 GHz, Tj < 100 ps and Rj about 2.5 ps is realized in the HLMC 55 nm low-power process. The PLL has built-in LPF capacitor with an area of about 1 000μm×300μm and an IO voltage of 3.3 V. The power consumption is less than 20 mW @ 3 GHz.

The noise calculation of amplifiers and filters will be given in this paper, because these noises determine the dynamic performance of ADC in the target frequency band.

Application of Intelligent Low Power Bluetooth BLE in Wireless System
WANG Xiaomin, ZHUANG Fei

Abstract: With the rapid development of science and technology, various devices have made the world more intelligent. The emergence of new technologies not only improves existing technologies, but also creates new market segments. The progress of Bluetooth technology makes intelligent Bluetooth (BLE, Bluetooth Low Energy) emerge as the times require. According to the definition of Bluetooth Technology Alliance, BLE is a low power, short distance, low data rate wireless communication protocol. BLE layered protocol stack can transmit a small amount of data with low power consumption and high efficiency, making it the preferred wireless protocol for battery-powered applications, such as low-power sensor network interface which needs to extract and process data periodically. This paper introduces how to effectively use BLE to maintain low power wireless operation in sensor applications where data changes are not frequent.
Key words: bluetooth low energy, BLE, wireless system
