The invention provides a beam limiting device CAN (Controller Area Network) bus shutdown self-recovery method and device and electronic equipment, and the electronic equipment comprises a processor, a memory and a computer program which is stored in the memory and can run on the processor. When the processor executes the computer program, a self-recovery method for closing the CAN bus of the beam limiting device is achieved; the method comprises the following steps: detecting a closing signal of a CAN bus node of the beam limiting device; s2, the micro-control unit obtains a closing signal of the CAN bus and generates a control instruction according to the closing signal; and S3, controlling the state of a CAN controller according to the control instruction, and enabling the CAN bus node to communicate with the CAN bus. According to the method, the integrity of CAN network communication is guaranteed through multiple means such as the first recovery, the second recovery and the forced restart process in seque
