(一)概述上海第二电表厂生产的MY4型101LED双光柱显示仪是采用INTEL公司MCS-51系列8位单片微处理机和低功耗集成电路、高亮度LED双光柱组成的智能化仪表,具有显示亮度高、功耗小、性能可靠、使用简便、外形小、抗干扰能力强的优点,并有自检、显示设置等功能,还留有充分的软件资源或扩展硬件开发位式等控制功能。当本仪器作为光柱显示仪外形 DDZ-S系列仪表的模拟量显示表头,或者配上各种不同模拟量输出的一次仪表,就能直观地显示自动化系统中流量、温度、压力、重量、转速等非电量的设置值和控制值。显示仪的外形如图1所示。
(I) Overview Shanghai Second Meter Factory production MY4 101LED dual-beam display is the use of INTEL’s MCS-51 series of 8-bit single-chip microprocessor and low-power integrated circuits, high-brightness LED double-beam composed of intelligent instrument , With the advantages of high brightness, low power consumption, reliable performance, easy to use, small size, strong anti-interference ability, self-test, display settings and other functions, but also leave sufficient software resources or expand the hardware development bit control function. When the instrument as a light bar display instrument shape DDZ-S series meter analog display header, or with a variety of different analog output of a meter, you can visually display the automation system flow, temperature, pressure, weight, speed Such as non-electricity settings and control values. Display appearance shown in Figure 1.
