摘　　要：为了实现实验室信息管理系统中检验设备类型众多、接口形式多样、软件开发难度大,更换设备不得不更换整套配套软件的难题,以RS232接口的MEJER-600尿液分析仪为例,设计了一种基于尿液分析仪的串口到遵循互联网协议的以太网口的转换装置,结合串口特点和TCP/IP协议,通过相关软硬件设计和LIMS服务器简易实验测试平台,完成该尿液分析仪在LIMS中归一化接入,实现基于IP节点的数据格式和交换协议的转换,小巧便携,经济实用。In order to solve the difficult problem about the laboratory information management system, such as many types of equipment, various forms of interface and difficult software development which led to the replacement of devices in the LIMS system is very hard.A case study of MEJER-600 urine analyzer used the RS232 serial port is designed, which is based on the serial port of the urine analyzer toTransfer interface follow the Ethernet port of the internet protocol.Combined with serial port features and TCP/IP protocol, the conversion device is designed which is based on the serial port of the urine analyzer to follow the Ethernet port of the internet protocol. Through the related software and hardware design and LIMS server test platform simulation access, the normalization of the urine analyzer in LIMS is completed, the data format and exchange protocol conversion based on IP node are realized, which is compact and portable, andthe cost of replacement is saved.
