以往,一些计量和显示计量数值的装置,如水表、电表、煤气表,其表本身带有数轮式或电子数字型计数器,需要人工抄表、处理,工作量大、效率低,不便更好地应用计算机处理。由于条码技术已形成一个体系,它作为信息自动输入和采集的编码技术成为信息处理技术中的重要应用领域。本文介绍一种实时显示条形码计数器是国家实用新型专利产品,具有普通电子计数器的常见功能,它是一种和条码技术兼容的实时显示条码计数器。该装置克服了现有技术的不足之处。提供了一种减少机械传动机构、以实时方式显示的条码计数器。它包括壳体、面框、二——十进制计数电路、译码电路、驱动电路及显示器件等,特别之处是显示器件由若干段可按条码字符信息规律显示的液晶模块紧密构成,接于驱动电路的输出端。因此,该计数器有着下列明显优点:
In the past, some devices for measuring and displaying metered values, such as water meters, electricity meters and gas meters, have their own digital or round counting counters that require manual meter reading and handling, heavy workload, low efficiency and inconvenience Application of computer processing. Since barcode technology has formed a system, it has become an important application field of information processing technology as a coding technology for automatic input and collection of information. This article describes a real-time display bar code counter is a national utility model patented product with common electronic counter common features, it is a bar code technology compatible with real-time display barcode counter. The device overcomes the shortcomings of the prior art. Provides a bar code counter that reduces mechanical transmission and displays in real time. The utility model comprises a shell, a face frame, a two-decimal counting circuit, a decoding circuit, a driving circuit and a display device, etc. The special feature is that the display device is formed by a plurality of liquid crystal modules which can display the regularity of bar code character information, Drive circuit output. Therefore, the counter has the following obvious advantages:
