背景技术 Background

[0002] 诸如例如密度计和Coriolis流量计的振动测量设备用于测量流动物质的特性, 诸如例如密度、质量流率、体积流率、总计质量流量、温度和其他信息。 [0002] The vibration measurement device, such as e.g. Coriolis flowmeter and densitometer for the total mass flow rate, temperature and other characteristics of the flow of information measuring substances, such as e.g. density, mass flow rate, volume flow rate. 振动测量设备包括一个或多个导管,其可以具有多种形状,诸如例如直的、U形的或不规则的配置。 Vibration measurement device includes one or more conduits, which may have a variety of shapes, such as for example straight, U-shaped or irregular configuration.

[0003] 一个或多个导管具有一组自然振动模式,包括例如简单弯曲模式、扭转模式、径向模式和耦合模式。 [0003] one or more conduits having a set of natural vibration modes, including for example, simple bending mode, torsional mode, radial mode and coupling mode. 为了确定流动物质的特性,至少一个驱动器在这些驱动模式之一中以谐振频率驱动一个或多个导管或者使其振动。 In order to determine the flow characteristics of the material, at least one driver in one of these drive mode resonant frequency to drive one or more conduits or vibrated. 一个或多个电子装置向该至少一个驱动器传送正弦或方波驱动信号,该至少一个驱动器典型地是磁体/线圈组合,其中该磁体典型地固定到导管而线圈固定到安装结构或者另一导管。 One or more electronic devices to the at least one drive transfer sine or square wave drive signals, the at least one drive magnet is typically / coil assembly, wherein the magnet is typically affixed to the catheter and the coil is fixed to a mounting structure or to another conduit. 驱动信号促使驱动器使一个或多个导管在驱动模式中以驱动频率振动。 Drive signal causes the drive enable one or more conduits to the drive in the drive mode vibration frequency. 例如,驱动信号可以是传送到线圈的周期性电流。 For example, the drive signal may be transmitted to a periodic current coil.

[0004] 至少一个感测器(pick-up)检测(一个或多个)导管的运动并且生成表示(一个或多个)振动导管的运动的正弦感测信号。 [0004] at least one sensor (pick-up) detect (s) the movement of the catheter and generates (one or more) sinusoidal vibration sensing signal conduit movement. 感测器典型地是磁体/线圈组合,其中该磁体典型地固定到一个导管而线圈固定到安装结构或者另一导管。 Typically the magnet sensor / coil assembly, wherein the magnet is typically affixed to a catheter coil is fixed to a mounting structure or to another conduit. 感测信号被传送到一个或多个电子装置;并且根据公知原理,一个或多个电子装置可以使用该感测信号来确定流动物质的特性或者在必要时调整驱动信号。 The sensing signal is transmitted to one or more electronic devices; and according to known principles, the one or more electronic devices may be used to determine the sensed signal characteristic of the flowing substance or adjust the drive signal, if necessary.

[0005] 为了在所期望的模式中驱动振动测量设备,典型地采用驱动链。 [0005] In order to drive a vibrating measuring device in a desired pattern, typically using a drive chain. 驱动链修改一个或多个感测信号以生成驱动信号。 Drive chain modifies one or more sensed signals to generate the drive signal. 驱动链增强适当的驱动频率并且抑制其他驱动频率。 Drive chain enhancer appropriate drive frequency and suppresses other drive frequencies. 作为示例,所生成的驱动信号可以始于感测信号。 By way of example, the drive signal may be generated begins sensing signal. 该感测信号然后可以被修改(例如滤除不期望的模式、调整信号增益和相移)以提供所生成的驱动信号。 The sensing signal can then be modified (e.g. filtered undesired pattern, gain and phase shift adjustment signal) to provide a drive signal generated.

[0006] 依赖于操作条件,给定的振动测量设备可以以特定频率更准确地操作。 [0006] depends on the operating conditions, a given vibration can be more accurately measuring device operating at a particular frequency. 例如,特定振动测量设备能够以低频的第一弯曲驱动模式或者高频的第二弯曲驱动模式进行操作。 For example, a specific apparatus capable of measuring the vibration of a low frequency first bend drive mode or a high frequency second bend drive mode of operation. 低频的第一弯曲驱动模式可以提供较好的夹带空气性能,而高频的第二弯曲驱动模式可以提供跨越较宽的操作条件范围的更准确的测量。 Low frequency first bend drive mode may provide better performance for entrained air, and the high frequency second bend drive mode may provide more accurate measurements over a wide range of operating conditions.

[0007] 作为一个实际问题,在振动测量设备被设计为在多个模式中操作的情形中,由于单个固定的驱动链不能生成一个以上模式,因此难以在模式之间切换。 [0007] As a practical matter, the vibration measurement device is designed to operate in the case of a plurality of modes, since a single fixed drive chain can not generate more than one model, it is difficult to switch between modes. 这在由于模拟硬件的固定的本质而包括任何模拟硬件作为驱动链的部件的情况中是特别成问题的。 This is due to the fixed nature of the analog hardware to include any analog hardware components as the drive chain case is particularly problematic.

[0008] 本发明涉及克服现有单导管系统中固有的这一缺点。 [0008] The present invention is directed to overcoming the disadvantages of existing single-duct system inherent.
