Compressors in Large Multi-room air conditioning system are often driven by gas heat pumps. The advantages of GHP are their high level of heating performance and low cost because they use the LNG fuel to drive engine. We developed engine control system. The developed system controls engine speed based on proportional, integral and derivative (PID) method. This controller is designed to eliminate the need for continuous operator attention on engine revolution control. The control system includes 4 spark coil drivers, fuel drivers and relay drivers to make engine"s operating more stable. The experiments of control engine revolution of this system are based on the various load conditions.

Recently, using GPS and equipment that recognizes the position of the car such a computer system inside the car are very universalized. Specially, the technique that diagnoses troubles and prevents troubles through scanning engine ECU is very popularized also. However, because these data have to be directly transferred and received from the car, in cases of traffic accident such as serious damage or car theft, it is impossible to receive the data at the time of accident. In order to receive and preserve the data safely regardless of these situations, it is possible to provide data for analyzing reasons of accident and prevent accidents from occurring by using wireless communication to receive the transferred information of the car, then saving into a Database system DB, or grasping the situation of the car and the driving pattern of drivers through analyzing stored data. Moreover, due to developing some related services such as providing the information about the real time of the accident, diagnoses of the car and alarms, etc. It is expected to contribute to creating added values.
