The utility model relates to a combined control system of a direct connecting miniature hydraulic pump for synchronously lifting bridges and a control device thereof. The combined control system comprises a plurality of direct connecting miniature hydraulic control devices. Each direct connecting miniature hydraulic control device comprises a high pressure electric pump, an electric control reversing valve, an oil tank and a jack; the output end of the high pressure electric pump is connected with the electric control reversing valve; a pipeline at the output end of the electric control reversing valve is connected with the jack; a displacement sensor is mounted in the position adjacent to the jack; and the electric control reversing valve, the high pressure electric pump and the displacement sensor in the direct connecting miniature hydraulic control device are respectively connected with a programmable automatic controller through a cable and connected to a control computer through the programmable automatic controller. The utility model has the advantages of small volume and light weight, can be conveniently fixed on an arranged scaffold platform or a pier, and is close to the jack; and the combined control system can be randomly combined for intelligently controlling the synchronous lifting of a bridge with a single section, a plurality of end surfaces and a variable end surface.
