The invention discloses an electro-hydraulic switch machine monitoring system, which comprises a plurality of monitors, each monitor is in one-to-one correspondence with an electro-hydraulic switch machine, each monitor is provided with an acquisition module, and the acquisition module is used for acquiring electrical parameters of the electro-hydraulic switch machine; and a monitoring station machine which is in communication connection with the monitors, and the monitoring station machine reads the electrical parameters of the monitors and generates a power curve and an oil pressure curve. Real-time measurement of oil pressure and power in the action process of the point switch is achieved, and meanwhile fault diagnosis and early warning are conducted on faults of the point switch according to a preset fault judgment strategy. In addition, statistical analysis can be carried out on real-time data of the turnout point switch, the influence of seasonal changes on the hydraulic turnoutis tracked, a maintenance
