The invention provides a control system for an attached vibrator used for shield segment concrete vibration. The control system for the attached vibrator used for shield segment concrete vibration comprises a power distribution cabinet, a PLC central processing unit, an input module, an output module, a communication module, an upper computer, a control button, a sensor, a signal indicator light and a pneumatic circuit. The input module provides a sensor signal and a button signal for the central processing unit. The output module executes an output signal of the central processing unit to drive all systems of the pneumatic circuit. Based on the PROFINET protocol, the upper computer interacts with the central processing unit through a communication module. According to the control system for the attached vibrator, parameters such as the vibration frequency, the vibration time, the amplitude and the pneumatic pressure can be monitored and controlled in real time, programmed control overthe attached vibrator is achieved, the labor intensity is relieved, the vibration process can be controlled, and excessive vibration and insufficient vibration are effectively avoided; and concrete quality problems such as bubbles, holes, honeycombs and pitted surfaces of shield segments are eliminated, and the concrete construction quality of the shield segments is ensured.
