压力校验台自动化校准系统

随着科学技术的发展，往往造成许多现场压力仪表虽到检定周期，却由于不能停产也就不能从作业。压力仪表的工作原理是弹簧管在压力或真空作用下产生弹性变形引起管端位移，其位移通过机械传动机构进行放大后再传递给指示装置，可在刻有法定计量单位的分度盘上读出指针所指示的被测压力值或真空量值。自动化校准系统的具体实现过程首先，标准源和数字多用表按照要求开机预热，连接硬件设备（gpib卡、488电缆等），硬件连接完成后，启动计算机，搜寻整个测试系统的物理地址分配情况，根据搜索到的各个仪器地址，在校准软件运行时，设置正确的地址配置。

Automated testing technology with the development of science and technology, collects and also got very big development, oversize is continuity of cohesion in each process of metallurgy manufacturing enterprises, although often cause a lot of pressure instrument to test cycles, but unable to stop production also cannot from the job. Working principle of pressure gauge is spring tube produce elastic deformation under pressure or vacuum tube displacement, the displacement

enlarged by mechanical transmission mechanism, and then passed to the indicating device, can be engraved with the legal unit of measurement on the dial of the measured pressure value indicated by the read pointer or vacuum. Automatic calibration system of the concrete implementation process first of all, the standard source and DMMS warmed up in accordance with the requirements, connecting hardware devices (gpib card, 488 cable, etc.), the hardware connection is complete, restart the computer, search for the physical address of the testing system distribution, according to search to the address of each instrument, the calibration software is run, set the correct address configuration.

初始化模块要设置被测试设备的校准项目，设置被校仪器和标准源的gpib地址，选择是否是首次测试，此功能的目的是为了保存测量的数据，防止意外发生使测量数据丢失，需要重新进行测试。选择中英文语言，选择校准、检定，选择被测试设备的名称。初始化设置就完成了。（2）数据采集动态显示模块。该模块的主要功能包括：初始化仪器、设置仪器的状态、测量数值、数据位数控制、动态

显示数据、数据结果判定、数据保存等。

Initialization module to set up test equipment calibration program, calibrated instruments are set and the gpib standard source address, choose whether to test for the first time, is the purpose of this function in order to save the measurement data, to prevent the accident makes the measurement data is missing, need to be tested. Choose Chinese and English languages, calibration, verification, by the name of the test equipment. Initialize the set up is completed. (2) the dynamic display of data acquisition module. The module's main features include: initialize the state of the instrument, set the instrument, measurement values, digit control, dynamic display data, data, results, data, etc.

本模块中的数据显示位数、数据量程、上下限等都是根据测试计量对仪器的要求而自动生成的，数据结果判定也是自动完成的。程序把那些不合格的数据用红色的字体显示，使计量员在测量结束后容易发现这些数据不合格。数据采集动态显示模块的前面板。（3）证书和原始记录生成模块。自动生成证书和原始记录，给计量员的工作带来极大的便利，而且消除了人为操作易产生的出错，解放了

劳动力。计量员只需在证书生成模块的前面板输入相关的仪器信息和校准信息，校准项目，选择相应的证书摸板，程序即可自动生成相应的校准证书和原始记录。证书模块的前面板。

Data display digits in this module, data range, the lower limit is according to the requirement of the test measurement equipment and automatically generated, the data result determination is also done automatically. Program to put those unqualified data in red font, according to the measurers through easy to find these at the end of the measurement data is unqualified. The front panel of the dynamic display of data acquisition module. (3) certificates and records generated module. Automatically generate a certificate and original records, to measurers through work to bring great convenience, but also eliminates the error caused by artificial operation, the liberation of the labor force. Measurers through just before the certificate generation module of the instruments panel input related information and calibration, the calibration program, select the corresponding
