The invention discloses a digital voltage detection control system based on an embedded technology. The system comprises an embedded control module, a voltage adjustment control module, a wireless communication module, a liquid crystal display module, an open-phase protection module, a voltage sensing module, a two-order filter module, a keyboard input module and a power module. The system realizes remote real-time monitoring on voltage data in a grid via mutual communication of an embedded controller and an upper computer. When the voltage required by a load is changed, an instruction can be sent at the far end via the upper computer to change the target voltage, and the voltage can also be directly adjusted via a keyboard on site. When the voltage in the grid is changed, a central controller receives a voltage value fed back by a voltage sensor, and sends a corresponding instruction via internal judgment to control a voltage adjustor to adjust the voltage in real time, thus protecting normal operation of th
