摘要：The existence of inpatient public health centers in remote areas needs to be supported with a data communication telemedicine system. The system includes remote station at each public health center which consists of telemedicine sensors such as the blood pressure monitor, the body temperature sensor, the electrocardiograph, the psych meter, and the heart rate monitor. The sensor circuits are connected to a modulator frequency shift keying (FSK) transceiver (Tx/Rx), and an antenna. The data is sent wirelessly to the base station. The base station device which is a computer-based control center was placed in a regency public hospital. The base station consists of an antenna, Tx/Rx, FSK demodulator, a PC (personal computer) with software. The results of the communication system test at Gunungkidul regency indicate that the accuracy level of the real time data measurement transmission has an average of 95 % at a distance of 0-40 km. The average of the successful data text transmission reached 97.6%. For the image data transmission, the received image quality decreased to 93.9% at a distance of 5 km and 55.3 % at a distance of 40 km. Variations of this quality degradation caused by distortion and interference of the frequency. The successful rate of the data transmission was sufficient for the purposes of early diagnosis, except for image data transmission remains to be improved.
