摘要： An impact protection controller for an electric height-adjustable desk. The controller comprises an MCU, a motor drive circuit, a motor current sampling circuit, a current amplifier circuit, a Hall pulse generator, and a Hall filter. The MCU controls the motor drive circuit. A signal transmitted by the Hall pulse generator is sent to the MCU via the Hall filter. A motor current is sampled by the motor current sampling circuit, and the result is sent to the MCU via the current amplifier circuit to detect a change of the current. The controller further comprises a shock switch provided outside of and connected to the MCU, or provided inside of the MCU. The present invention combines current detection and shock detection to improve sensitivity and reliability of impact protection.
