Abstract
With the changes in lifestyle and environment, health status is taken more and more attention. The demand of Chinese medicine instruments has been growing. With the effective integration of modern science and technology and traditional Chinese medicine basic theory research, TCM electrical measurement techniques have been developed and improved rapidly. The health status is diagnosed by measuring electric information of the 24 meridian points in the hands. It provides effective measures to achieve “preventive treatment of disease” and helps people better to manage health. Meridian electric measuring technology promotes the development of traditional Chinese medicine. However, the existing health monitoring devices are single-channel measurement, larger, generally used in hospitals and do not apply to family and leisure facilities.
PIC16F873A microcontroller is used as the core to control signal transmission and disposal in the lower computer of the palm health detector. Analog multiplexer switches are taken to achieve 24-channel gating. Hand models and the measurement sensors are connected to collect information. The signals after being adjusted and converted will be transferred to the client-side by the conversion chips through the USB port. The lower computer program is designed to control the 24-way signals, initialize MCU and transmit data.
Through the instrument commissioning and the clinical validation, the results show that the stability and accuracy of the instrument meets the testing requirements and the business needs of the project side. Keywords: health detector, PIC16F873A microcontroller, the language of C#, database

and SQL Server 2008 is used as database. Software includes data processing, user information management, network communication and database. Data processing achieves data comparison, fitting and dynamic display. The operation of the database, and network communication between client-side and server-side is used to manage user information and diagnose measuring results.
在中医理论的基础上，结合网络技术、电测量技术研制出了掌型健康检测 仪。掌型仪的研制主要包括下位机测量系统的设计与上位机软件功能的实现。
掌型健康检测仪的下位机以 PIC16F873A 单片机为核心来控制信号的传送处 理。采用模拟多路转换开关来实现 24 通道的选通，手模和测量传感器相接实现 信息的采集，采集到的信号经调整、转换后通过串口转换芯片经 USB 口传到客 户机端。下位机程序主要是实现 24 路信号的选通，单片机的初始化和数据的传 送。
The palm type health detector is invented on the basis of Chinese medicine theory, network technology and electrical measuring technology, including the measurement system design of the lower computer and the software function implementation of the upper computer.
