Welding temperature measurement system of solar cell sheet

The invention discloses a welding temperature measurement system of a solar cell sheet. The system comprises a control system, a cell sheet, a temperature acquisition module, a line power strip, a temperature sensing module and a system placing box. Multiple data acquisition lines are led out from the temperature acquisition module and other ends of the data acquisition lines are fixed on the line power strip. A sensing line is led out from the line power strip and is electrically connected with the temperature sensing module. The control system, the cell sheet, the temperature acquisition module, the line power strip and the temperature sensor are installed in the system placing box in a centralized manner when not in use. According to the invention, temperature of different points on a main grid line of the cell sheet is simultaneously measured through the temperature sensing module, and after the temperature acquisition module transmits related data to the control system, the control system carries out ana
