The invention relates to a synthesized multi-service gate control terminal, in particular to the synthesized multi-service gate control terminal which integrates gate opening/closing visual control, pro-gate water level measurement, post-gate water level measurement, pro-gate scene monitoring, post-gate scene monitoring and intercom based on IP between a scene and a main control center into a whole. The synthesized multi-service gate control terminal solves the problems that as three major subsystems are independent from each other, the existing gate control system has slow response, low efficiency, high cost, complex installation and operation, and the like, in terms of gate control and ship-pass dispatching. The gate control terminal consists of an embedded type CPU based on ARM, an extension video input processing circuit, an audio input/output circuit, an RJ45 communication interface, a WLAN communication interface, a switching value input/output interface circuit and a 485 communication interface. The terminal of the invention can access to the Internet, can realize remote gate opening/closing visual control and remote voice broadcast ship-pass dispatching, thus leading to convenient and safe gate opening/closing and ship-pass dispatching.
