The invention relates to a support controller for an electro-hydraulic control system. The support controller for the electro-hydraulic control system is technically characterized by comprising an MCU processing unit, a code matching communication unit, a display unit, CAN receiving and transmitting communication units, a sensor collecting unit, an audible and visual alarm communication unit, an electromagnetic valve driver communication unit and an emergency stopping/shutting unit, wherein the code matching communication unit, the display unit, the CAN receiving and transmitting communication unit, the sensor collecting unit, the audible and visual alarm communication unit, the electromagnetic valve driver communication unit and the emergency stopping/shutting unit are connected with the MCU processing unit, each CAN receiving and transmitting communication units is connected with a support controller body adjacent to the CAN receiving and transmitting communication unit, the sensor collecting unit is connected with a travel sensor and a pressure sensor, the audible and visual alarm communication unit is connected with an audible and visual alarm, the electromagnetic valve driver communication unit is connected with an electromagnetic pilot operated valve through an electromagnetic valve driver, the emergency stopping/shutting unit is connected with the electromagnetic valve driver communication unit, and the code matching communication unit is connected with a handheld remote controller. By the adoption of the support controller for the electro-hydraulic control system, the reliability of the support controller product is improved, the production cost of keyboard installation is reduced, the installation position of the audible and visual alarm can be flexibly arranged according to on-site conditions, and the production safety is improved.
