技术领域本发明涉及一种设置于各家庭的气体供给管入口部分来测量气体流量的气体流量计，具体涉及为提供按气体器具的费用等与使用器具及其使用方法一致的新费用、服务而对使用中的气体器具进行判别检测的技术。 Technical Field The present invention relates to a gas supply pipe disposed at an inlet portion of the one kind each home to measure the gas flow rate gas flow, and particularly relates to a novel cost consistent with use of the appliance and to provide a method by using a gas appliance costs, services the use of the gas appliance for detecting the identification technology. 背景技术以往，作为各种流量测量装置的例子，例如有日本专利申请特开2002 — 71421号公报所示的构造。 BACKGROUND ART Examples of the various flow measurement devices, for example, Japanese Patent Application Laid-Open 2002-- configuration shown Publication No. 71,421. 一般而言，各家庭中会在气体供给线的入口安装内藏有气体流量计的气体计。 Generally, each home will be mounted with a gas flow meter built in the gas meter inlet gas supply line. 以往的气体计，在执行按器具的费用的情形下，使用连接于气体计的多个积算装置，求出使用特定时间时的积算流量、使用特定范围的流量时的积算值，即，求出按时间区分流量、按流量区分的流量，以该积算值决定费用体系。 Conventional gas meter, in the case of implementation costs of the appliance by using a plurality of integrating means connected to the gas meter, the integrated flow rate obtained when using a particular time, using the integrated value when flow rate of a specific range, i.e., to determine the time to distinguish between traffic, according to traffic flow distinction to the totalizer value determines the fee system. 利用图13加以说明费用体系的l例。 EXAMPLE l FIG. 13 to be described is the cost of the system. 预先设定预定的折扣流量区分及预定的折扣时间带，以相当于该折扣流量区分及折扣时间带的流量的气体费用为折扣对象，即，图13中以斜线区分的部分为对象。 Preset predetermined discount flow rate class and a predetermined discount time zone, the cost of gas equivalent to the discount flow rate class and the discount time zone traffic to be discounted, i.e., hatched in FIG. 13 to distinguish the part of the object. 然而，由于此方法中，器具的特定判断是不明确的，进行对特定器具收取费用等更让消费者易懂、方便的费用设定是有困难的。 However, since this method, a particular judge appliance is not clear, it is charged to the specific appliance costs leaving consumers to understand, easy to set fees is difficult. 在此，作为用以判别特定器具的方法，例如有日本专利申请特开2003—149027号公报所示的提案。 Here, as a method for determining a specific appliance, for example, Japanese Patent Application Laid-Open No. 2003-149027 Publication proposal shown. 利用图14说明此种流量测量装置的动作。 FIG 14 illustrates such an operation using a flow rate measuring device. 图14表示当某种气体器具启动时的气体流量变化模式，及依据该模式进行模式匹配的参考值（模式表）。 FIG 14 indicates that when the gas flow rate change pattern at start of a gas appliance, and reference values for pattern matching (pattern table) according to the mode. 对1个气体器具而言，此模式表必须准备随气体器具的燃烧控制所发生的一连串气体流量变化模式部分，并且，各家庭所使用的气体器具总台数部分是必要的。 For a gas appliance, the table must be prepared to this mode a series of changes in gas flow mode portion of gas appliances with combustion control occurred, and the total number of units part of the gas appliance used by each household is necessary. 平常，比较由气体计的流量测量装置所测出的流量值变化与该模式表， 一边提取匹配的， 一边特别指定器具。 Normal, the flow rate value change by the gas flow measuring means comparing the measured count and the pattern table, while matching the extracted, while specifying the appliance. 然而，上述现有构造中，为了进行器具判别，必须预先储存维持气体器具一连串的气体流量模式，但使用气体器具多时，其数据量会增加，同时要进行比较判别也很花时间。 However, the above-described conventional structure, in order to perform appliance discrimination, the appliance must be pre-stored sequence of gases to maintain the gas flow pattern, but the use of a gas appliance is large, the amount of data increases, while also compared determination takes time. 此外，用以判别的装置也很贵，气体计本身的成本也会增加。 Further, means for determining is also very expensive, the cost of the gas meter itself will increase. 除此之外，同时使用多个器具时， 必须推定其组合，准备气体流量模式，且由于其组合所产生的量庞大， 因而会发生难以进行多个器具的判别的问题。 In addition, when using multiple appliances must be presumed to combinations thereof, to prepare a gas flow rate mode, and since the amount of generated combinations considerable and difficult to discriminate the plurality of appliances may occur. 发明内容本发明的流量测量装置，包含有：以一定时间间隔测量流量的流量测量器；求出自该流量测量器输出的流量值的差分值的运算器；器具信息储存器；及比较由运算器算出的差分值与登记于器具信息储存器内的启动判定值的大小，以对连接于流量测量器下游侧的器具的使用进行判定的器具判别器。 Flow measuring device of the present invention, comprises: a time interval measuring device measuring the flow of traffic; by seeking the difference value of the flow rate value output from the flow rate measuring device operator; storage appliance information; and a comparison operation is calculated with the difference value registered in the appliance information storage start determination value of the size used for the connection to the downstream side of the flow measuring device of the appliance determination unit of appliance determination. 根据此构造，可提供判别时间很短且在多个器具的情况下也可判别的流量测量装置。 According to this configuration, it provides very short time is determined and the flow rate measuring apparatus in the case where a plurality of appliances may be discriminated. 附图说明图1是本发明实施方式1中流量测量装置的构造图。 BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a configuration diagram of embodiment of the invention the flow measuring device 1. 图2是图1所示的流量测量装置中流量测量部的构造图。 FIG 2 is a flow rate measurement apparatus 1 shown in FIG flow rate measurement unit configured to FIG. 图3是图1所示的流量测量装置中判别动作的流程图。 FIG 3 is a flowchart showing the flow measurement device shown in FIG discriminating operation. 图4是图1所示的流量测量装置中的流量及运算值的图。 FIG 4 is a view of a flow and the calculated value of the flow rate measurement apparatus 1 shown in FIG. 图5是图l所示的流量测量装置中的流量及运算值的另一图。 Figure 5 is another view of a flow and the calculated value of the flow rate measuring device shown in FIG l. 图6是本发明实施方式2中判别动作的流程图。 6 is a flowchart of the embodiment 2 of the discriminating operation. 图7是本发明实施方式2中判别动作的另一流程图。 FIG 7 is a flowchart of another embodiment of the present invention, the operation of the second discriminating. 图8是本发明实施方式3中流量测量装置的构造图。 FIG 8 is a configuration in embodiment 3 of the present invention showing the flow rate measuring device. 图9是图8所示的流量测量装置中的流量的图。 9 is a flow measurement device shown in FIG. 8 in the flow of FIG. 图10是第8图所示的流量测量装置中的流量的另一图。 FIG 10 is another view of the flow of the flow rate measuring device shown in FIG. 8. 图11是本发明实施方式4中的流量的图。 FIG 11 is a flow rate in the FIG. 4 embodiment of the present invention. 图12是本发明实施方式4中流量测量装置的构造图。 FIG 12 is a configuration diagram of the embodiment of the present invention the flow measuring device 4. 图13是现有流量测量装置中判别方法的概念图。 FIG 13 is a conventional method of determining the flow rate measuring device a conceptual diagram. 图14是现有流量测量装置中判别方法的数据构造图。 FIG 14 is a data structure of a conventional flow rate measurement device discrimination method. 符号说明1…流量测量装置2…气体阻断阀3…流量测量计4…显示部5…感震器6…运算器7…器具信息储存器8…器具判别器9…控制电路10…测量流路11、 12…超声波发送接收器13…器具登记器14…流量信息储存器15...按器具的流量算出器16…信息压縮器具体实施方式以下，利用附图来说明本发明的实施方式。 Description of Symbols 1 ... 2 ... a gas flow rate measuring device cutoff valve flow meter 3 ... 4 ... 5 ... display unit sensing seismic operator 6 ... 7 ... 8 ... appliance information storage appliance determination control circuit 10 ... 9 ... stream measurement path 11, 12 ... ultrasonic wave transmitting and receiving register 13 ... 14 ... appliance flow rate information storage according to the flow calculator 15 ... 16 ... appliance information compressor specific embodiment described below, embodiments of the present invention will be described using the drawings the way.

另外，本实施方式中流量测量装置1的流量测量器3，是使用作为瞬时流量测量器的超声波流量计（超声波方式的测量器）。 In the present embodiment, the flow measurement flow measuring device 1 of 3, using an ultrasonic flowmeter as an instantaneous flow measurement device (the ultrasonic method of measuring). 作为测量方式，只要是以射流(fluidic)方式等可在短时间内以一定循环连续测量即可，也可使用其它流量测量方式。 As the measurement method, as long as the jet is (Fluidic) mode and the like can be measured continuously at a constant cycle in a short time can also be used other flow measurement. 以下，说明本实施方式的流量测量装置1的动作。 Hereinafter, the operation of the apparatus 1 according to the embodiment of the flow rate measurement. 首先，利用图2 说明有关超声波方式的流速测量。 First, about 2 illustrates an ultrasonic flow measuring method. 图2中，测量流路10的截面为矩形。 In FIG. 2, the measurement flow path 10 has a rectangular cross section. 在与测量流路10的气体流动方向呈直角方向的壁面上，以夹住测量流路10，且在流路的上游测与下游侧具有一角度4)而倾斜对向安装一对超声波接收器11及12。 On the wall surface of the gas flow direction of the measurement flow channel 10 in the direction perpendicular to sandwich the measuring flow path 10, and having an angle measured upstream and the downstream side flow path 4) inclined to the mounting of a pair of ultrasonic receivers 11 and 12. 超声波发送接收器11及12的作用是在两者间交互发送接收超声波，并以一定间隔对流体的流动计算顺方向与逆方向超声波的传播时间差，将其作为传播时间差信号而输出。 Acting ultrasonic transmitter 11 and the receiver 12 receives the ultrasonic wave is transmitted between the two interact at certain intervals and calculates the ultrasonic flow direction of the fluid in the forward direction and the reverse propagation time difference, the propagation time difference as an output signal. 计算器（未图示）接收该传播时间差信号，并算出被测量流体的流速及流量。 A calculator (not shown) receives the signal propagation time difference, and calculates the flow velocity and the flow rate of the fluid measured. 其运算式如下。 The calculation formula is as follows. 图2中，L为测定距离，且以tl为从上游的传送时间，t2为从下游的传送时间，则流速V可以V-(L/2cos4))X(l/tl — 1/t2)表示。 In FIG. 2, L is a measured distance, and at the time tl is transmitted from the upstream, t2 is a transmission time from the downstream, the flow velocity V can be X (l / tl V- (L / 2cos4)) - 1 / t2) represents . 测量时间间隔可设定在超声波可发送接收的范围内，但本实施方式1中是以2秒间隔进行测量。 Measuring the time interval can be set within the range of ultrasonic wave transmission and reception, but the present embodiment is the embodiment 1 was measured at 2 second intervals. 此外，縮短时间间隔在测定原理上是可行的。 Furthermore, it is feasible to shorten the time interval on the measurement principle. 由于也有气体器具在低于2秒的时间内启动的器具，因而縮短测定时间间隔在瞬时进行器具判别方面是有利的，但縮短测量间隔则会发生使电池消耗变大等课题，还有，若与现有气体计所使用的膜式方式同样的测量间隔为2位数量级的秒数间隔，则不易看着本实施方式1中的算法的流量变化的差分来判断测量时间。 Since the gas appliance has started within a time less than 2 seconds, the appliance, thus shortening the measurement time interval is determined in terms of instantaneous appliance is advantageous, but the consumption of the battery to shorten the measurement interval like problem occurs becomes large, and, if conventional manner with the gas meter membrane used in the same measurement interval of the order of two-digit number of seconds, the flow rate change is not easy to look at the difference method of the present embodiment determines a measurement time. 因此，本实施方式1中，从成本及器具判别的性能方面来看，作为平衡的较佳时间， 是以2秒间隔进行测量。 Accordingly, the present embodiment 1, the cost and appliance determination performance point of view, a preferred balance of time, is measured at 2 second intervals. 接着，利用图3说明气体器具动作状态的判别顺序。 Next, FIG. 3 illustrates the sequence determines the operating state a gas appliance. 流量测量装置l是如上所述，每2秒间隔测量流量，将该数据送至运算器6，将流 L flow measuring device as described above, the flow rate interval measurement every 2 seconds, the data is sent to the operator 6, will flow
量值微分，作为每2秒的流量的差分数据而输出。 Differential value as the flow rate difference data is output every 2 seconds. 该差分数据是逐次送至器具判别器8，再与登记于器具信息储存器7的启动判定值进行比较。 The difference data is sequentially sent to the appliance determination unit 8, and then registered in the appliance information storage 7 start determination value. 当差分值超过比较判定值时，则判断为气体器产生状态变化。 When the difference value exceeds the comparison determination value, it is determined that a gas is generated state change. 由于一旦检测此变化，即可进一步判断怎样的气体器有怎样的状态，故器具判别器8可与登记于器具信息储存器7的各气体器具的按状态的变化值进行比较，来进行器具的判别。 Once this change detection since, further to determining what kind of state of the gas has, and therefore the appliance determination unit 8 may be compared with the change value by state of the appliance registered in the storage information of each gas appliance 7, to the appliance discrimination. 图4中显示实际气体器具使用时的气体流量的变化与差分值的变化。 Shows the change of the gas flow rate variation when the actual gas appliance using the difference value in FIG. 4. 图4的曲线中，实线表示利用流量测量器所测出的气体流量值， 虚线为此时的微分值，即，表示每2秒的差分值。 4 graph, the solid line represents the gas flow rate value measured by the flow rate is measured by the dotted line is a case of the differential value, i.e., represents the difference value every two seconds. 气体器具启动时， 差分值会以在正数侧维持峰值来表现，停止时会以在负数侧维持峰值来表现。 When the gas appliance starts, the difference value will be maintained at a positive side to peak performance, we will maintain peak performance in a negative side to stop. 另外，图5中以曲线显示同时使用3个的器具A、器具B及器具C时的流量值与差分值。 Further, FIG. 5 graphically displays simultaneously use three appliances A, the flow rate value and differential value when appliances appliance B and C. 可根据此曲线，读取3个器具分别在启动时与停止时的变化。 According to this curve, and stop reading when the variation 3, respectively appliance starts. 还有，作为判别所得的信息，只要可确认是把来自器具储存器7 的信息通过控制电路9显示于显示部4，或者是向外部终端机（未图示） 的数据传送，均可使用。 Further, as the determination information obtained as long as the information is confirmed from the reservoir 7 of the appliance by the control circuit 9 displays the display data transfer unit 4, or to an external terminal (not shown), may be used. (实施方式2)图6是本实施方式2中判别动作的流程图。 (Embodiment 2) FIG 6 is a flowchart of the embodiment 2 of the present embodiment determines the operation. 第2实施方式与第1 实施方式的相异点在于可将运算器6所进行的流量值的差分时间变更成测量最短时间间隔（实施方式1中为2秒）的整数（N)倍来进行。 The second embodiment is different from Embodiment 1 in that the time differential value of the flow rate calculator 6 may be performed to measure the minimum time interval is changed (Embodiment 1 in 2 seconds) integer (N) times to . 基本的流量测量装置1的构造及功能与上述第1实施方式相同。 The basic structure and function of the flow rate measuring apparatus 1 of the first embodiment. 第2实施方式中，使以运算器6进行差分的时间与登记对应，将其设定变更至2秒的整数倍。 The second embodiment described above, so that the time differential corresponding to the registered operator to 6, which is set to change to an integral multiple of 2 seconds. 由于气体器具的不同，也有启动时的起 Due to the different gas appliances, but also from the time of start
始吋间长的情形，即使靠2秒间的差分可得知变化，但其变化量与怎样的器具对应，因为不进行变化途中过程的流量判别，所以难以判别的情形很多，对于此种器具，可视对应器具信息储存器7的登记信息而改变差分时间，进行判定，就能做出正确的判定。 Inch long between the beginning of the case, even by a difference between the two seconds that changes, but the change amount corresponding to how the appliance, since no change in the way the process of determining the flow rate, it is difficult to distinguish many circumstances, for such appliances , the time difference changes, determination can be made correctly determined corresponding to the visual information appliance registration information storage 7. 另外，实施方式l及实施方式2中，虽然以测量间隔的基准为2秒来计算差分，但测量间隔及差分运算的基准不是2秒也可执行器具的判别。 Further, in the embodiments l and 2 embodiment, although the reference to the measurement interval is 2 seconds to calculate a difference, but the measurement interval and the reference differential operation is not 2 seconds may also perform determination of an appliance. 图7是本发明实施方式2中判别动作的另一流程图。 FIG 7 is a flowchart of another embodiment of the present invention, the operation of the second discriminating. 图7所示的流程图，是在差分值超过比较判定值且气体器具发生状态变化的情形下，为了进一步判断是何种气体器具，器具判别器8可与登记于器具信息储存器7的各气体器具的器具判定值比较，进行器具的判别。 Flowchart shown in FIG. 7, a case where more than the comparison value and determining a state change occurs in the gas appliance difference value, in order to further determine what kind of a gas appliance, the appliance determination unit 8 may be registered in the appliance information of each reservoir 7 appliance gas appliance determination value comparison, determination of an appliance. 此时，具有在没有与此判定一致的登记数据的情形下，增加差分时间， 直到获得与登记数据一致的运算值为止，反复与差分值增量进行比较的功能。 In this case, having determined in the absence of registration data consistent with this case, the time difference increases, until a consistent value with the registered data operation is repeated until the difference value with a function of comparing increments. 据此，即使是无法以2秒差分判别的器具数据，也可利用自动增加差分时间使器具的判别成为可能。 Accordingly, even if the appliance is not a 2-second differential data is determined, it may be utilized to increase the differential time for the automatic determination of an appliance becomes possible. (实施方式3)图8是本发明实施方式3中流量测量装置的构造图，图9是图8 所示的流量测量装置中的流量的图。 (Embodiment 3) FIG. 8 is an embodiment of the present invention is constructed in FIG. 3 a flow measurement apparatus of FIG. 9 is a flow flow measurement device shown in FIG. 8 in FIG. 图8所示的实施方式3中的流量测量装置与图1所示的实施方式1中的不同点在于，具有储存流量测量器3的流量值的流量信息储存器14;及把由流量测量器3在一定时间内测量的测量流量信息作为器具流量信息进行登记的器具登记器13。 Different from Embodiment 1 shown in FIG. 8 embodiment illustrated embodiment the flow measurement device 3 of FIG. 1 in that, the flow rate information storage 14 having a flow rate value of the flow rate measurement reservoir 3; and the flow from the measuring device 3 measured flow rate information measured for a certain time the appliance registered in register 13 as the appliance flow information. 由于基本的流量测量装置1的构造及功能与实施方式1相同，故省略此部分说明。 Since the same basic structure and function of the flow rate measuring device 1 of Embodiment 1, description thereof is omitted in this section. 以下，说明本实施方式3中特有的动作及作用。 Hereinafter, embodiment 3 of the present embodiment and the specific operation effect. 首先，可通过器具判别器8的动作，判别动作器具的台数。 First, the operation of the appliance can be determined by the number 8, the appliance discriminating operation. 本实施方式3中说明关于判别仅仅1台进行动作的内容。 Described in the third embodiment according to the present embodiment is determined solely on the contents of a table for operation. 例如，以流量测量器3测出的流量，从0流量（由于包含接近0 For example, the flow measuring device 3 to the flow rate measured, the flow rate from 0 (because it contains close to 0
流量，故为0土3L/h)，发生预定流量（例如，10L/h以上）的变化时， 则判别为1台器具动作。 Flow, so that the soil is 0 3L / h), when the occurrence of a predetermined flow rate (e.g., 10L / h or more) changes in the operation of the appliance is determined as a table. 接着，以此时的测量流量时间变化作为测量流量信息，并开始储存。 Subsequently, the flow rate at this time was measured as the time variation measured flow rate information, and begins to store. 此储存动作，是以在预定时间内（例如，30 秒）持续储存，而所储存的数据用作时间系列的流量模式数据。 This storage operation is based (e.g., 30 seconds) stored in a predetermined duration of time, and the data stored as time-series data traffic patterns. 所储存的流量模式数据显示于图9。 Stored data traffic patterns shown in FIG. 在此，说明了从0的变化，但也附记0 流量略微持续的状态（例如，IO秒以上）的变化。 Here, the change from 0 Appendix 0 but slightly sustained traffic state (e.g., more than IO seconds) changes. 接着，设置流量测量装置1后，设定从1天至1周左右（可变更设定）的预定期间内自动持续动作。 Automatic operation within a predetermined time duration Next, the flow measuring device 1 is provided, is set from about 1-1 days (change setting) of. 此期间可定位为学习期间，器具判别器8判别为在此学习期间仅使用1台器具时，器具登记器13可将气体器具的测量流量信息登记于器具登记器13。 When during the learning period may be positioned, the appliance determination unit 8 determines that during this learning to use only one station appliance, the appliance registration device 13 can measure the flow rate of gas appliance information of the appliance registered in the register 13. 还有，为了储存仅1台进行动作的时间带的测量流量信息作为器具流量信息，而不会几次都储存相同的器具流量信息，根据器具开始使用的起始流量变化及绝对流量值等进行判断、学习，防止双重登记。 Further, only one table to store the time information with the traffic measurement operation as the appliance flow information, are stored several times without the same flow rate information appliance, the appliance flow rate change according to the start and began to use the absolute value of the flow rate or the like judgment, learning to prevent double registration. 在此，登记器13动作而自动登记时，不易判断所登记的器具是何种器具，故不执行与器具的种类（例如：热水器或气体灶等）的对应。 Here, when the register 13 and the operation of automatic registration, not easy to determine what appliances registered appliance, the appliance so that the type is not performed: correspond (e.g. a gas stove or a water heater, etc.). 但是，后续的动作实际上是在器具判别器8动作了时，则以采用与器具的种类对应的方式来进行。 However, follow-up actions in fact at the time of operation of the appliance determination unit 8, using the places corresponding to the type of appliance to the way. 还有，器具登记器13可依需要进行动作，在得知进行动作的器具为何的时候，对于所测出的测量流量信息，可将是何种器具（例如热水器或气体灶等）登记于器具信息储存器7。 In addition, the appliance can also need to register 13 operates, in that the appliance operates why the time measurement for the measured flow rate information, which may be a fixture (e.g., a gas stove or a water heater, etc.) is registered in the appliance information storage 7. 例如，依照气体灶（小口、大口、格架）、气体热水器的顺序，反复点火、停止，即可依序特别指定已完成动作的器具，且作为测量流量信息的器具流量信息的对应气体器具，可分别与已完成动作的顺序对应起来。 For example, in accordance with a gas stove (small mouth, big mouth, grid), the order of a gas water heater, repeated ignition is stopped, can be sequentially specified completed actions appliance, and as the measured flow rate information corresponding to the gas appliance appliance flow information, it may correspond to the operation sequence is complete. 并且，也可以并用自动地设定学习期间再登记的方法及依序手动地启动预定气体器具的方法进行学习，进行登记数据的追加或更新。 And, it may be used to automatically re-registration period setting method and learning method of sequentially activated manually predetermined gas appliance learning, is additionally registered or updated data. 接着，关于器具判别器8所判别的器具方面，按器具的流量算出 Next, the appliance determination unit 8 aspects of the appliance discriminating, the appliance flow rate is calculated according to
器15是随着其所登记的流量算出装置，算出每个器具的流量值。 15 it is registered as the flow rate calculating means calculates the flow rate value for each appliance. 由于通常是同时使用2台以上的气体器具，故要算出每个器具是有困难的， 而本实施方式3中，是求出图IO所示的每个区段的流量，并以该区段的变化流量幅度为基础，与气体器具对应起来，按器具累计流量。 Since usually use two or more sets of gas appliances, each appliance is calculated to be so difficult, but the present embodiment 3, as shown in the flow is determined for each segment of FIG IO, and to the section amplitude change based on the flow rate, in association with the gas appliance, the appliance according to the cumulative flow. 例如，图10所示的模式中，区段l，若从开始的流量变化判别为气体扇加热器（gas fan heater)，则区段1、区段2与区段3可以作为气体扇加热器的流量来算出。 For example, the pattern shown in FIG. 10, the segments L, when the flow rate change start determination gas fan heater (gas fan heater), then zone 1, zone 2 and zone 3 can be used as a gas fan heater the flow rate is calculated. 然后，剩下区段4的流量是从全流量中扣除气体扇加热器的流量，即区段1至区段3的流量来求得。 Then, the remaining section 4 is the flow rate of gas flow fan heater is subtracted from full flow, i.e. flow zone 3 to zone 1 be obtained. 还有， 其它的方法有，根据使用时间，基于预定计算式来推定流量的推定方式等，不论何种方法，测定精度都会有误差，但均可由器具判别器8 特别指定器具，以求出每个器具的流量。 Also, there are other methods, according to time, based on a predetermined calculation formula to estimate the estimated flow mode and the like, regardless of the method, the measurement accuracy will have an error, but can be specified by the appliance determination unit 8 special tool, in order that each a flow appliances. (实施方式4)图11是说明本发明第4实施方式中流量测量装置1的器具判别器8的数据储存的流量模式的特性图，图12是实施方式4中流量测量装置的构造图。 (Embodiment 4) FIG. 11 is a characteristic diagram showing a data discriminator appliance fourth embodiment of the present invention, the flow rate measuring apparatus 1 is stored in the 8 traffic patterns, FIG. 12 is a configuration diagram of the fourth embodiment of the flow measuring device. 仅说明本实施方式4与实施方式1的不同点。 Only the differences between the present embodiment and Embodiment 4 of the embodiment 1. 图12中， 流量信息储存器14包含对流量值在时间轴方向进行信息压縮、储存的信息压縮器。 In FIG. 12, the flow rate information storage 14 contains information on the flow rate value in the compression axis direction, the information stored in the compressor. 艮口，信息压縮器16，在图11所示的流量模式时，在流量稳定流动的区域，在时间轴方向压縮数据。 Gen port information compressor 16, the flow mode shown in FIG. 11, in the region of a steady flow of traffic, data compression in the time axis direction. 实施方式1中虽已说明用以判别流量开始模式的方法，但本实施方式4中是参照以器具从开始使用至停止的被压縮的数据来判别器具，且被压縮期间的起点与终点的数据于流量信息储存器7中作为信息被登记，再算出器具的使用流量的情形。 Although embodiment 1 described a method for determining the flow rate of the start mode, but the fourth embodiment according to the present embodiment with reference to the compressed data from the beginning to the appliance use stop of the appliance is discriminated, and compressed during starting and ending data flow information to the reservoir 7 is registered as the information, and then calculates the case of using the appliance flow rate. 在长时间使用的情形下，由于全流量数据会变成庞大的数据量， 故可如上所述，省略稳定时的流量数据并进行时间压缩，以作为少的流量数据。 In the case of prolonged use, since the full-flow data becomes a huge amount of data, it can be as described above, when the steady flow data and time compressed omitted, as less data traffic. 所压縮的流量数据为气体计的时间系列的测量流量值，但亦可将预定时间间隔的差分流量值进行时间压縮。 The flow rate of compressed gas meter data time-series measurement flow rate value, but also the flow rate value difference is a predetermined interval of time compression. 由上述可清楚地了解，本发明的流量测量装置包含有：以一定时间间隔测量流量的流量测量器；求出自流量测量器输出的流量值的差分值的运算器；器具信息储存器；比较由运算器算出的差分值与登记于器具信息储存器内的启动判定值的大小，判定连接于流量测量器下游侧的器具的使用的器具判别器，据此构造，可以简便的算法，且以与测定器的测量时间对应的速度，判定器具使用状态的变化。 Can be clearly understood from the above, the flow rate measuring apparatus according to the present invention comprises: measuring the flow at time intervals the flow rate measuring device; demand flow rate value by the difference value output from the flow rate measuring device operator; storage appliance information; Comparative calculated by the arithmetic unit and the difference value registered in the appliance information storage size determination start value, it is determined using the appliance determination unit is connected to a downstream side of the flow measuring device of the appliance, whereby the structure can be simple algorithm, and with measuring with the measurement time corresponding to the speed variation determined appliance use state. 还有，器具判别器是做成比较由运算器算出的差分值与登记于器具信息储存器的多个器具判别值的大小，从多个器具中判别所使用的器具的构造，据此，可掌握动作中的器具的台数、判别多个器具的使用状况。 Further, a plurality of appliance determination is made by the appliance determination value comparison operator and the calculated difference value registered in the appliance information of the size of the reservoir, the appliance discriminating configured to be used from the plurality of appliances, accordingly, can be grasp the number of appliance operation, usage of multiple discrimination appliances. 还有，运算器是做成可对取从流量测量器输出的流量值的差分的时间任意地进行变更的构造，由于可任意改变差分时间，故可对应每个器具的流量变化的时间差异，适当地读取各器具的气体使用的流量变化。 There, the operator is made for the differential flow rate value output from the time taken for the flow measuring device configured to change arbitrarily, since the time difference can be arbitrarily changed, it may correspond to the time difference of each appliance change flow rate, changes in flow properly read each gas appliance used. 还有，器具判别器是做成当从流量测量器输出的流量的差分值超过登记于器具信息储存器的启动判定值时，可将运算器所计算的差分时间增加至与登记于器具信息储存器的器具判别值一致，并根据一致了的差分时间来判别所使用的器具的构造，据此，可合格地读取使用气体器具的流量变化。 Moreover, the appliance determination is made if the difference value outputted from the flow rate exceeds the flow rate measuring device information registered in the storage of the appliance to start determination value, the operator may increase the time difference calculated to the registered information stored in the appliance appliance determination value is consistent, and the appliance is configured to discriminate to be used in accordance with the same time difference, accordingly, be qualified read using flow rate change of gas appliances. 还有，其是做成还包含有：储存流量测量器的流量值与测量时间的测量流量信息的流量信息储存器；及把在一定时间内所测出的测量流量信息作为器具判定值而登记于器具信息储存器的器具登记器，比较器具登记器所登记的器具判定值与以流量测量器测出的测量流量信息，判别连接于流量测量器下游侧的使用器具的构造，据此，储存登记所测出的测量流量信息，就可判别多个器具的使用状况，同时只要 Also, it is made further comprising: flow information measured flow rate information storage value and the measured flow time flow measuring reservoir; and the time within a certain measured flow rate information measured value is registered as the appliance determination an information appliance in the appliance registration storage, the comparator register appliance determination value registered in the appliance flow rate with the measured flow rate information measured by the measuring device, connected to the downstream side of the structure determines the flow rate using a measuring instrument, whereby, storage registering the measured flow rate information measured, a plurality of conditions can be determined using the appliance, at the same time as long as
预先登记为哪一种的器具（热水器及气体灶等），就可特别指定所使用的器具。 Which is registered in advance for the appliance (gas stoves and water heaters, etc.), specifying the appliance can be used. 还有，器具判别器是做成判断为l个器具动作时，把测量流量信息作为预定的器具信息而登记于器具登记器的构造，据此，可测定仅为1台动作时的流量信息，可登记正确的信息，故可提高器具判别精度。 When there is, the appliance determination is made of the operation of the appliance is determined as a l, the measured flow rate information as the predetermined information appliance registered in the appliance configuration register, whereby, when the flow rate information can be determined only one stage operation, information can be properly registered, it can increase the accuracy of appliance determination. 还有，器具登记器是做成可依需要进行动作，靠第2次以后的动作对过去的登记数据进行追加或更新、学习的构造，据此，由于登记数据可追加或更新，因而即使使用新器具，也可进行器具判别。 Also, the appliance registration is made to follow the need for action, on the second and subsequent actuations of past registration data added or updated learning structure, whereby, due to the registration data can be added or updated, so even with new appliances, but also for the appliance determination. 还有，流量信息储存器是做成包含有对流量值在时间轴方向进行信息压縮、储存的信息压縮器的构造，据此，可在稳定时的流量变动少时，把流量变化上未表现出器具特征时等的信息舍去而进行压縮保存，从而减少数据量，且可减轻微电脑等的处理负荷，因而特别适合以电池驱动的情形。 Further, the flow rate information storage is made with the value of the traffic information compressed in the time axis direction, the configuration information stored in the compressor, accordingly, can vary the flow rate is small when the stable, not on the flow rate change when information is discarded appliance exhibits features like compression and stored, thereby reducing the amount of data, and reduce the processing load such as a microcomputer, which is particularly suitable in the case of battery-powered. 还有，其是做成还包含有依据器具判别器的结果来算出每个器具的流量的按器具的流量算出器的构造，据此，由于使用器具判别所得的结果算出按器具的流量，故在气体器具的情形下，可建构按器具的费用体系，且在为工厂的情形下，可对每个器具进行流量管理。 Further, it is configured to make further comprising an appliance determination results based on the calculated flow rate for each appliance by the appliance flow rate calculating unit, whereby, since the appliance determination results obtained by the appliance flow rate is calculated, so in the case of gas appliances, the appliance may be built according to the fee system, and in the case of the plant is, traffic can be managed for each appliance. 还有，流量测量器是做成使用作为瞬时流量测量器的超声波流量计的构造，据此，可在流量变化瞬间进行器具判别动作及学习动作， 并且可通过捕捉细微流量变化，提高器具判别精度。 In addition, flow measurement is made using the configuration of the ultrasonic flowmeter as an instantaneous flow measurement device, according to which the appliance determination operation can be performed in a learning operation and the instantaneous change in traffic, and can change the flow by capturing subtle, enhance the accuracy of appliance determination . 工业实用性本发明的流量测量装置，可判别流路上连接何种器具，即使在使用多个器具的情形下，也可得知所使用的器具台数，或者只要根据流 Industrial Applicability The flow rate measuring apparatus according to the present invention, the flow path may be determined what the appliance is connected, even in the case of using a plurality of appliances, the appliance may be that the number of units used, or according to the flow as long as
量信息特别指定器具，就可得知是使用怎样的器具。 Specified amount of information appliances, you can learn how to use the equipment. 还有，本发明可逐次运算从测量器输出的瞬时流量的差分值的变化，且以该变化量为基础来判定气体器具的使用状态的变化，可对应测量器的测定速度， 在短时间内判定使用器具，同时在测量的算法上也比流量的模式匹配简便，因而判别所需的器具的成本也低。 Further, the present invention can sequentially change in the difference value calculating instantaneous flow rate output from the measuring device, and the change amount is determined to change the state of a gas appliance used, may correspond to measuring speed measuring device is based in a short time determining use of an appliance, but also the flow rate is lower than the simple pattern matching, thereby discriminating the desired measuring appliance cost algorithm. 还有，由于气体器具使用中， 其它器具动作时的判别也着眼于流量值的差分值，因而较为容易，且器具判别的可靠性提高，器具判别可采用简便的算法而具有高判定能力，可提供与使用设备对应的气体费用的设定等新的服务，或者，可进一步适当地变更使用器具所对应的安全设定值。 Further, since the gas appliance in use, when the other appliance determination operation is also focused on the difference value of the flow rate value, and thus easier, and improving the reliability of appliance determination, the appliance determination can be a simple determination method has high capacity, provision and use of the device is set corresponding to the cost of gas and other new services, or can be further appropriately changed security setting values corresponding to the use appliance.
