In order to solve the problem of poor portability, inconvenience for handhold and mobile inspection, difficult for upgrade and update of the existing information monitoring terminal in the industrial field, we propose a handled monitoring terminal based on voltage quality disturbance generator. The terminal is consist of communication converter and Android APP. Communication converter communicate with the industrial field devices based on RS232, and transmit transparently the data to the Android APP via WiFi to accomplish data acquisition and transmission. Android APP is designed to receive the data of industry scene transferred from the communication converter, and to realize the functions of data realtime display, preservation, warning and so on. Experiment results show that the terminal can acquire data based on different parameters in RS232 industrial interfaces, transmit wirelessly data based on WiFi and visualize monitoring data on Android APP.
