具体实施方式 Detailed ways
下面结合附图对本实用新型作详细说明： Below in conjunction with accompanying drawing, the utility model is described in detail:
如图1、图2所示，图中：1、表盖，2、表盖环，3、水表铜罩，4、表盘，5、表盘面，6、水表本体。 As shown in Fig. 1 and Fig. 2, in the figure: 1, table cover, 2, table cover ring, 3, water meter copper cover, 4, dial, 5, dial surface, 6, water meter body.
其包括水表本体、表盖和表盘，水表本体上设有水表铜罩，水表铜罩与水表本体之间螺纹连接，还包括表盖环，表盖环的侧边部与表盖环枢轴连接，表盖环套在水表铜罩上，表盖环与水表铜罩可转动连接，在表盘上方设有光电传感器，光电传感器通过导线连接单片机，表盘的表盘面均分为黑色和白色两部分。 It includes a water meter body, a meter cover and a dial. The water meter body is provided with a water meter copper cover. The water meter copper cover is threaded with the water meter body. It also includes a cover ring. The side of the cover ring is pivotally connected to the cover ring. , the cover ring is set on the copper cover of the water meter, and the cover ring and the copper cover of the water meter are rotatably connected. A photoelectric sensor is arranged above the dial, and the photoelectric sensor is connected to the single-chip microcomputer through a wire. The dial surface of the dial is divided into black and white parts.
当水表转动开始计量时，由于指针转动一圈所代表的水量（也叫脉冲当量）是固定的（这个由水表本身特性所决定），同时通过单片机进行时间的抓取，由于单片机的响应时间为1.28×10-7秒，完全可以忽略不计，这样可在一个脉冲周期内得出水表瞬时流量，再与标准的流量进行比对，可得出水表的瞬时流量相对误差。由于在某一个测试点上，使用的时间是一致的，所以瞬时流量相对误差等同于水表相对误差。这样可在一瞬间算出该水表的误差值。 When the water meter rotates to start measuring, since the water volume (also called pulse equivalent) represented by the pointer rotation is fixed (this is determined by the characteristics of the water meter itself), at the same time, the time is captured by the single-chip microcomputer. Since the response time of the single-chip microcomputer is 1.28×10 -7 seconds, completely negligible, so that the instantaneous flow of the water meter can be obtained within one pulse period, and then compared with the standard flow, the relative error of the instantaneous flow of the water meter can be obtained. Since the time used is consistent at a certain test point, the relative error of the instantaneous flow rate is equal to the relative error of the water meter. In this way, the error value of the water meter can be calculated in an instant.
