仪表显示与按键示意图1． 上电。
接通电池，LED 指示灯先亮3~5秒然后连续快闪10次，并且LCD 全显则程序初始化正确，如不闪烁则为电台初始化不正确需要检查电路,全显一段时间后液晶显示初始界面，电路进入测试状态，大概经过一分半钟后，才进入正常工作状态。
在测试状态时通过手操器可以修改仪表的参数。
2． 在显示压力界面下，长按确认键大概5秒，可从测试状态快速进入正常工作状态，如果在正常工作状态，按此键5秒，也可从正常工作状态，快速进入测试状态，此时的状态可以和手操器进行连接，也可以通过手操器进行以下的设置。
称重传感器、力传感器技术服务手册
低温：使用在温度低于-30℃的场所，如冷冻试验。 5 按准确度级别分类
根据传感器的综合性能分为 A、B、C、D 四个级别 6 按结构分
1）柱式；2）剪切梁式；3）平行梁式；4）板环式；5）S 型；6）弯曲梁式等 五、称重传感器的基本应用
主要应用在各种电子衡器、工业控制领域、在线控制计量、安全过载报警、材料实验机等领域。 1）、电子汽车衡；2）、电子台秤；3）、电子叉车秤；4）、动态轴重秤；5）、电子吊钩秤；6）、电子计 价秤；7）、电子钢材秤；8）、电子轨道衡；9）、连续累计自动衡器；10）、重力式自动衡器；11）、自动分 检衡器；12）、称重模块（用于料斗秤、配料秤、罐装秤及其工业领域）
与所加的激励电压有关，所以额定输出的单位以 mV/V 来表示。并称之为灵敏度。
*灵敏度允差
传感器的实际稳定输出与对应的标称额定输出之差对该标称额定输出的百分比。例
如，某称重传感器的实际额定输出为 2.002mV/V，与之相适应的标准额定输出则为
2mV/V，则其灵敏度允差为：（（2．002 – 2.000）/2.000）*100% = 0.1%
传感器的线性误差、滞后误差以及在规定温度范围内由于温度对灵敏度的影响所引起的误差等的总和不能
超过误差带 δ。这就允许制造厂对构成计量总误差的各个分量进行调整，从而获得期望的准确度。
称重传感器按转换方法分为光电式、液压式、电磁力式、电容式、磁极变形式、振动式、陀螺仪式、
电阴应变式等 8 类，以电阻应变式使用最广。

美瑞 М1500数字压力传感器手册说明书
DigitalPressure TransmitterM1500 + Meriam = Performance you can rely on!Meriam’s compact, M1500 Analog or Digital Pressure Transmitters are ideal for pressure measurement needs from 10” H 20 to 3000 PSI Full Scale. Output options include digital (RS-232, RS-485 and USB) or analog (mA or V DC). Choose from differential (dry/dry or wet/wet), gauge, compound or absolute pressure types – see the table below for complete details. Typical NIST traceable digital accu-racy is ±0.025% of F.S. including all effects of linearity, repeatability, hyster-esis and temperature from -20º to +50º C (-4º to +122º F).Digital output options for the M1500 deliver accurate pressure measure-ment to compatible receiving devices. Choose RS-232 single point or RS-485 for networks up to 255 devices. M1500 connections are made via terminal block or DB-9 serial port. The USB digital communication option also pow-ers the M1500 via high power USB ports or powered USB hubs.Software is included for initial setup and support. Meriam Serial Protocol (MSP) or Meriam DLL can be used to send and receive information. Implementation Guides are available at (see Resources / Application Notes).Analog output models are also avail-able. Output accuracy is typically ±0.035% of F.S. The user may config-ure the M1500 for 0 – 5 VDC or 4 – 20mA output. Two SPST opto switches are included. Analog units are config-ured using a USB Mini A Connector and the included Meriam Setup Utility. The utility supports initial configura-tion, zeroing, recalibration and other functions.For wider pressure range require-ments, model M1502 with digital out-put incorporates two pressure sen-sors. Most combinations of AI or CI type pressure sensors are supported. See the table below for available rang-es. M1502 is available with RS-232, RS-485 or USB digital outputs - not available with analog output. A single software command returns both pres-sure readings. The M1502 reduces purchase price and installation costs when multiple pressure measurements are needed.(Orifice plate, Venturi, Accutube, Wedge)• Clean room pressure monitoringStandard AccessoriesP/N Z9A000003PN06 Support Disk including: - Meriam Setup Utility- Meriam Serial Protocol Implementation Guide - USB Device Drivers & Installation Instructions - LabVIEW® VI’s- Meriam DLLOptional AccessoriesP/N Z9P273Analog Starter Kit, 6 ft.

OMEGA PX540 Series 压力传感器操作手册说明书
PX540 Series Pressure Transducers Operator’s Manual: M1137/0698General DescriptionThe OMEGA®PX540 Pressure Transducer consists of a pressure connection section with welded stainless steel diaphragm and a case for housing the electronic equipment and the electrical connection. The piezoresistive pres-sure sensor is installed behind the diaphragm, with the intervening space filled with silicone oil as pressure trans-mission liquid.The pressure sensor’s signal is converted by an amplifier to a signal of 4 to 20 mA. The pressure connection DIN 3852 is used as a seal behind threads by means of the added NBR O-ring. (No flush-mounted seal). Characteristics of this transducer include:• 4 to 20 mA current output which is ideal for long distance signal transmitting and industrial environments.• High accuracy and repeatability.• Corrosion resistant, and• Rugged NEMA=12 dust-tight/drip-tight enclosure.How To Adjust Zero and SpanNOTE:Unit has been factory calibrated. No adjustment isrequired upon delivery from OMEGA Engineering.Zero adjustment must be performed at no pressureand the output reading must be 4 mA.Span adjustment must be performed at full scale pres-sure and the output reading must be 20 mA.If you do not get either of these readings at therequired no pressure or full scale pressure, go through the following procedure to get to the screws. Remove the connector from the body of the transmit-ter as described in steps 1 and 2 in the Wiring Section. Adjust the zero screw so the output reading is 4 mA at no pressure. At full scale pressure, the output must be 20 mA; if it is not, adjust the span screw.The Zero screw is marked with a white dot. The span screw is marked with a red dot. Refer to Figure 1.Figure 1. Location of AdjustmentScrewsWiringTo access the screw terminals and wire the transducer, refer to Figure 2, and the following procedure.1.Locate the screw at the top of the transducer and unscrew.2.Separate connector from the rest of the transducer body.

《传感器与检测技术》基于多传感器的老年人跌倒检测报警系统设计设计
《传感器与检测技术》跌倒检测器摘要：随着人口老龄化进程的加快，老年人监护和医疗问题正成为一个重大的社会问题。
老年人意外受伤害的首要原因就是跌倒，因此，研究助老产品——跌倒检测器，将大大改善老年人的健康品质，对构建和谐社会的意义重大。
本课题设计了一种基于多传感器的老年人跌倒检测报警系统，依托嵌入式单片机STM32F101R8T6，利用普通的加速度传感器，对人体的空间三个方向的加速度值进行采集，倾角传感器采集人体的前后和左右倾角值，并且脚底压力传感器感知脚部的压力值。
关键词：跌倒检测，多传感器，倾角传感器1 前言1.1 课题背景21世纪的来临，使全世界范围内人口老年化的进程加快，在这种全球趋势的情形下，中国也不例外，随着我国人口老年化进程的加剧，社会对这一群体的健康保障将承担越来越艰巨的责任。
年龄的增长，身体解剖组织结构和生理代谢发生变化，由于自身疾病或者外界的影响，老年人常会发生意外跌倒，有时候甚至是健康的老年人也会发生，据国外研究机构统计，约有的超过65岁的老人平均每年发生一次跌倒，且随着年纪的增加，概率也增加，而本身身体有病痛或者伤害的老人，就更容易发生意外的跌倒。
而跌倒次数巨大的背后，是由跌倒带来的辅助治疗所需消耗的高昂费用，以及照顾跌倒人群消耗的巨额社会资源，有研究表明，社会支付的医疗费用超过50万亿元，而付出的代价则为160-800万亿元人民币。
然而，跌倒造成的伤害不仅体现在身体的即时受伤，还体现在未得到及时的帮助而造成的所有后续恶劣影响。
所以，针对跌倒问题，除了做好事先防范工作之外，如安全教育等，还应该在发生跌倒时，最快的将受伤人员送往医院进行救治，所以发明一个能够实时监测到跌倒并通知医护人员救治的产品很重要。
1.2 国内外研究现状目前对老年人跌倒检测技术相关研究主要的研究成果是利用加速度传感器检测装置,监测在跌倒事件发生时人体各方向加速度值，利用阈值检测或者模式识别的方法，对老年人的身体姿势状态进行实时检测，算法判断到处于跌倒状态后，再利用远程无线报警系统进行报警，通知护理人员进行救治，实现老年人的远程监护。
