The personal computer was used as a control center that serves to send and receive data from a mobile phone and microcontroller on the slave units. The data communication between the central computer with the microcontroller running by using multipoint asynchronous serial communication with a baudrate of 57600 bps.

From the test results show that the system of information services and reservation queue numbers can work well.
