【正文】 language, upper PC control software uses LABVIEW and ACCESS to design. System software is mainly posed of upper PC munication software, field monitor node temperature collection, process, and control algorithm software, etc. Software system adopts modular design, which divides into some relative independent function module, and arranges suitable enter and exit port parameters. On system designing, in order to avoid munication jamming, different patient bed patient terminal controller and monitor temperature sensor work in different frequency segment, each ward subcontroller must carry out address code to monitoring temperature if it wants to know which sensor transmitting temperature. Address code has two kinds of style: protocol addressing and nonprotocol addressing. Nonaddressing uses NRF905 RF configuration register, transmits address register to address, so, substation can decide which monitoring temperature sensor transmits data. Protocol addressing includes substation address and monitoring temperature address of transmitting data. So, subcontroller can judge which sensor transmits transceiver physical address adopts its default address 0xE7E7E7E7。 this system adopts protocol addressing style, and subcontroller and respectively defines monitoring temperature sensor munication frame format. Each subcontroller only has an address, and its length is one byte. Monitoring temperature sensor address length is two byte. Command word is one byte. When mand word addresses is 0x55, subcontroller informs this monitoring temperature sensor to collect data and upload. In order to make different wards independent, each subcontroller has unique address, its length is one byte, monitoring temperature sensor address is byte, and temperature data is two byte.A.

Temperature monitors software flowSCM software of lower PC software is development by C Language, which mainly realizes data collection, NRF905 wireless data transmitting and receiving, etc. It can be divided into some modules such as below: selfcheck module, transceiver module, and body temperature monitor module, etc. Among them, temperature monitor software flow is shown as Figure 7.D. Upper PC monitorUpper PC software mainly realizes munication, LABSQL Server database visit, and data monitor, etc based on visual instrument software . We adopt G Language to design software program frame, and set munication data collection and transmitting, as well as use software LABVIEW strong graph display function to design front panel demonstration interface, which can greatly increase interactive function of humanmachine. V. EXPERIMENT AND CONCLUSIONTo monitor system accuracy and reliability, we use mercurial thermometer measure some patient body temperature, pare to temperature value of this system measure, and adopt takingpoint style at same time. Through experiment, measurement error absolute value is less than ?C, which matches clinic medical body temperature monitor. This system uses digital temperature monitor network, adopts wireless munication, which realizes each patient body temperature connecting with central PC, and connects work central station with upper PC by USB interface, overes tradition electric cable laying disadvantages, shortens and simplifies cable layout, as well as saves fixing cost.System accuracy and precision is proved by experiment, system hardware has many advantages of sample structure, higher measurement precision, convenient extension, and easy to realize multimonitoring point, long distance monitor and munication. This system also can plete other health and clinic monitor by adding various monitor sensor.17
