The host housing 2 is provided with a CPU5, and a power management module 6 connected to the CPU5, a battery module 14, a GPS module 7, a GPRS communication module 8, an infrared communication module 9, a Bluetooth communication module 10, a liquid crystal display module 11, and a camera module 12 and serial interface 13 . The power management module 6 is used for low voltage management, and separates voltages required by different modules. GPRS module 7 is used to connect to the wireless network, and upload the real-time debugging data of the station area to the cloud database through the network, and the database will give the next step instructions to the debugging station area or directly locate according to the cloud data according to the uploaded data and the built-in program of CPU5 to possible failures. The power circuit 4 is connected to the power management module 6 , and the power management module 6 is connected to the USB interface module 15 and the battery module 14 .

In the hand-held platform area debugging terminal of the utility model, the power line carrier module 3 that comes with it can monitor the information of the carrier area by connecting to the power line, and can also read the carrier energy meter at different nodes in the area to realize the control Carrier link testing.
