The invention relates to a work platform control system and aerial work platform equipment, the work platform control system comprises a constant flow source, a first execution device, a second execution device and a flow control valve, and the constant flow source is configured to provide hydraulic oil with preset flow; the first execution device comprises a first execution mechanism and a first main control valve; the second execution device comprises a second execution mechanism and a second main control valve; the flow control valve is connected with the constant flow source, and when the first main control valve is located at the working position, the flow control valve is configured to enable the constant flow source to supply oil to the first execution mechanism under the condition that the pressure of an oil inlet way of the first execution mechanism is smaller than the sum of the load pressure of the first execution mechanism and the preset pressure; when the second main control valve is located at the working position, the flow control valve is configured to enable the constant flow source to supply oil to the second executing mechanism under the condition that the pressure of the oil inlet way of the first executing mechanism is larger than or equal to the sum of the load pressure of the first executing mechanism and the preset pressure or the first main control valve is located at the non-working position.

    本发明涉及一种作业平台控制系统和高空作业平台设备,其中,作业平台控制系统包括恒流源、第一执行装置、第二执行装置和流量控制阀,恒流源被配置为提供预设流量的液压油;第一执行装置包括第一执行机构和第一主控阀;第二执行装置包括第二执行机构和第二主控阀;流量控制阀与恒流源连接,在第一主控阀处于工作位时,流量控制阀被配置为在第一执行机构的进油油路的压力小于第一执行机构的负载压力与预设压力之和的情况下使恒流源向第一执行机构供油;在第二主控阀处于工作位时,流量控制阀被配置为在第一执行机构的进油油路的压力大于或等于第一执行机构的负载压力与预设压力之和或第一主控阀处于非工作位的情况下使恒流源向第二执行机构供油。
