【摘要】：放大变换电路测试系统是放大变换电路板生产、验收环节中的重要组成部分,其在放大变换电路板的验收环节中起着至关重要的作用。本课题是与国内某研究院相互合作,为其生产研制一种可以进行放大变换电路测试的设备。要求设备具有在一定温度范围内,对放大变换电路板输出的电信号能进行准确测量的功能,并且满足其调试与测试放大变换电路板要求。在放大变换电路中对电路板输入一定的电流信号,在输出端可以接收到相应频率的脉冲信号,因此放大变换电路也被叫做“I/F变换电路”。该电路已被广泛的应用于各种军工设备中,如导弹、雷达、火箭等。在对放大变换电路测试系统的研究方法中,传统的测试方法在一个温度循环时间里只能测试一发放大变换电路板,当需要测试多发放大变换电路板时,需要反复持续操作多个温度循环的过程,不但增加了操作者的工作量,而且消耗了大量的时间,降低了工作的效率。针对传统测试方法效率低的这一特点,本文提出了一种网络化的放大变换电路测试系统,与以往传统测试方法相比,它不但能在一个温度循环时间里测试五发放大变换电路板,大大的缩短的测试的时间,减小里操作者的工作量,提高了测试的效率,而且可以通过局域网实现对产品指令的下达,通过数据库进行数据上传,保证了被测产品信息采集的实时性以及被采集数据的精准性。本文根据实际被测产品的性能指标和应用需求,生产并研制了一台基于网络化的放大变换电路测试系统。测试系统主要由研华工控机、NI计算器板卡PCI-6602、NI多功能板卡PCI-6221、放大变换电路测试箱、横河恒流源GS200以及高低温箱等组成。测试过程中将放大变换电路板置于高低温箱内,等温箱达到设定温度时,通过恒流源给电路板提供相应的电流信号,当电流信号进过放大变换测试箱时,将相应的电流信号转换为频率信息,此时通过LabVIEW软件采集生成的频率信号,并将其保存到相应的数据库中。当生产厂家对被测电路板下达测试指令时,可以直接通过局域网下达测试指令,操作者就根据生产厂家的指令对被测产品进行操作；当生产厂家要对被测产品数据进行查阅时,可以直接通过局域网调出存储在数据库中的被测产品的信息,极大的提高的测试信息的实时性,同时减少了因为人工操作的失误而造成的损失。本文通过结合制造执行系统(MES),建立局域网,实现对被测系统信息实时化的远程监控。
[Abstract]:Amplifier transform circuit testing system is an important part of the circuit board production and acceptance, which plays an important role in the acceptance of the amplifier conversion circuit board. This project is to cooperate with a domestic research institute to develop a kind of equipment which can be used for amplifying and converting circuit testing. It is required that the device can accurately measure the electrical signal output from the amplifier and transform circuit board within a certain temperature range, and meet the requirements of debugging and testing the amplifier conversion circuit board. In the amplifier converter circuit, a certain current signal is input to the circuit board, and the pulse signal of the corresponding frequency can be received at the output end. Therefore, the amplifier conversion circuit is also called the "I / F conversion circuit". The circuit has been widely used in various military equipment, such as missiles, radar, rockets and so on. In the research method of amplifying conversion circuit test system, the traditional test method can only test one amplifier transform circuit board in one temperature cycle time, when the multiple amplification conversion circuit board needs to be tested, The process of repeated and continuous operation of multiple temperature cycles not only increases the workload of the operator but also consumes a lot of time and reduces the working efficiency. In view of the low efficiency of the traditional test methods, this paper presents a networked test system for amplifying and transforming circuits. Compared with the traditional test methods, it can not only test the circuit board with five radiations in a temperature cycle time. Greatly shorten the test time, reduce the workload of the operator, improve the efficiency of the test, and through the LAN to achieve the delivery of product instructions, through the database for data upload, It ensures the real-time and the accuracy of the collected data. In this paper, according to the performance index and application requirement of the product under test, a network based test system of amplifier and transform circuit is developed. The test system is mainly composed of PCI-6602NI multi-function board card PCI-6602NI, amplifying and converting circuit test box, transriver constant current source GS200 and high and low temperature box. In the process of testing, the circuit board is placed in a high and low temperature box. When the isothermal box reaches the set temperature, the current signal is supplied to the circuit board through a constant current source. When the current signal enters the test box, The corresponding current signal is converted into frequency information, and the frequency signal is collected by LabVIEW software and stored in the corresponding database. When the manufacturer issues the test instruction to the circuit board under test, it can send the test instruction directly through the local area network. The operator operates the product under the instruction of the manufacturer, and when the manufacturer wants to consult the data of the product under test, The information of the tested products stored in the database can be directly transferred through the LAN, which greatly improves the real-time performance of the test information and reduces the loss caused by human error. In this paper, a local area network (LAN) is established by combining the manufacturing execution system (MES),) to realize the remote monitoring of the real-time information of the system under test.
