[0022] The present invention will be further described below in conjunction with the drawings and embodiments.
[0023] This embodiment provides a method for controlling the movement of the brainwave therapy bed, which includes the following steps:
[0024] Step S1: such as figure 1 As shown, a treatment bed motion control device is provided, including a capture card, a brain wave sensor connected to it, and a core controller (the controller is composed of a high-speed data processing unit FPGA, which is processed by algorithms and sends instructions through an antenna array receiver To the treatment bed), the signal transmitter and the treatment bed perform signal transmission through the wireless network; the signal transmitter includes an antenna array transmitter and an antenna array receiver, the antenna array transmitter is connected to the core controller, and the antenna array receiver is connected to the treatment bed The antenna array transmitter and the antenna array receiver perform signal transmission through wireless sensor network technology to perform unmanned movement of the treatment bed; in this embodiment, the treatment bed is a six-degree-of-freedom mechanical arm treatment bed;
[0025] The brain wave sensor collects the brain wave blink times of the brain controller and transmits it to the acquisition card. The core controller converts the collected electrode signals into control signals, and transmits them through the signal transmitter to control the treatment bed movement;
[0026] Step S2: The core controller uses different electrode signals, that is, different brain wave blink times, to form different control signals to control the migration action of the treatment bed movement. The migration action includes the movement of the treatment bed, hovering, Move left, move right, move forward, move backward, move up, move down and pause actions;
[0027] Step S3: After the movement of the treatment bed is unlocked, if the brain wave value received by the core controller stabilizes above 40, a control signal is sent to control the movement of the treatment bed; when the movement of the treatment bed is moved to a certain height (80cm) After that, it will be in a hovering state, waiting for the core controller to form different control signals through different brain wave blink times to control the movement of the treatment bed.
[0028] In this embodiment, the command starting point and the command cycle of the motion of the treatment bed are set; the command cycle is N seconds, and N is a natural number greater than zero. If the command cycle of the motion of the treatment bed is set to 4 seconds (the time can be Adjust), beyond 4 seconds, the movement of the treatment bed enters the next instruction cycle; the starting point of the movement of the treatment bed is the movement of the treatment bed in the air hovering as the starting point of the instruction, the count of all brain wave blinks is based on the movement of the treatment bed in the hovering state as Starting point calculation.
[0029] In this embodiment, when the motion of the treatment bed is in the hovering state: if the brain wave sensor collects one brain wave blink, the core controller controls the motion of the treatment bed to switch to the left shift state .
[0030] In this embodiment, when the motion of the treatment bed is in the left shift state: if the brain wave sensor collects 0 brain wave blinks, the core controller controls the motion of the treatment bed to keep the left shift state; If the brain wave sensor collects one brain wave blink, the core controller controls the motion of the treatment bed to switch to the right shift state; if the brain wave sensor collects two brain waves in the first instruction cycle When the wave blinks, the core controller controls the motion of the treatment bed to switch to the forward state; if the brain wave sensor does not collect a signal in the first command cycle, it collects two brain waves in the second command cycle. When the wave blinks, the core controller controls the motion of the treatment couch to switch to the up-moving state.
[0031] In this embodiment, when the motion of the treatment bed is in the right-shift state: if the brain wave sensor collects 0 brain wave blinks, the core controller controls the motion of the treatment bed to keep the right-shift state; If the brain wave sensor collects one brain wave blink, the core controller controls the motion of the treatment bed to switch to the left shift state; if the brain wave sensor collects two brain waves in the first instruction cycle When the wave blinks, the core controller controls the motion of the treatment bed to switch to the forward state; if the brain wave sensor does not collect a signal in the first command cycle, it collects two brain waves in the second command cycle. When the wave blinks, the core controller controls the motion of the treatment couch to switch to the up-moving state.
[0032] In this embodiment, when the motion of the treatment bed is in the forward state: if the brain wave sensor collects 0 brain wave blinks, the core controller controls the motion of the treatment bed to maintain the forward state; If the brain wave sensor collects one brain wave blink, the core controller controls the motion of the treatment bed to switch to the backward state; if the brain wave sensor collects two brain waves in the first instruction cycle When the wave blinks, the core controller controls the motion of the treatment bed to switch to the left shift state; if the brain wave sensor does not collect a signal in the first command cycle, it collects two brain waves in the second command cycle. When the wave blinks, the core controller controls the motion of the treatment couch to switch to the up-moving state.
[0033] In this embodiment, when the motion of the treatment bed is in the backward state: if the brain wave sensor collects 0 brain wave blinks, the core controller controls the motion of the treatment bed to maintain the backward state; If the brain wave sensor collects one brain wave blink, the core controller controls the motion of the treatment bed to switch to the forward state; if the brain wave sensor collects two brain waves in the first instruction cycle When the wave blinks, the core controller controls the motion of the treatment bed to switch to the left shift state; if the brain wave sensor does not collect a signal in the first command cycle, it collects two brain waves in the second command cycle. When the wave blinks, the core controller controls the motion of the treatment couch to switch to the up-moving state.
[0034] In this embodiment, when the motion of the treatment bed is in the up-moving state: if the brain wave sensor collects 0 brain wave blinks, the core controller controls the motion of the treatment bed to keep the up-moving state; If the brain wave sensor collects 1 brain wave blink, the core controller controls the motion of the treatment bed to switch to the down state; if the brain wave sensor collects 2 brain wave blinks, then The core controller controls the movement of the treatment bed to switch to the left shift state.
[0035] In this embodiment, when the motion of the treatment bed is in the downward movement state, if the brain wave sensor collects 0 brain wave blinks, the core controller controls the motion of the treatment bed to maintain the downward movement state; If the brain wave sensor collects 1 brain wave blink, the core controller controls the motion of the treatment bed to switch to the up-moving state; if the brain wave sensor collects 2 brain wave blinks, then The core controller controls the movement of the treatment bed to switch to the left shift state.
[0036] In this embodiment, when the motion of the treatment bed does not receive the control signal sent by the core controller within 2 consecutive instruction cycles, the motion of the treatment bed will be automatically suspended.
[0037] The principle of this case: The rhythmic potential changes generated by the brain are directly transmitted from the scalp or from the cerebral cortex through brain wave sensors (electrodes) and wires to a special core controller, which is composed of a high-speed data processing unit FPGA. The algorithm processes and sends instructions to the treatment couch through the antenna array receiver.
[0038] Generally, the frequency range of brain waves related to normal brain electrical activity is divided into five types, with frequencies from high to low, followed by γ wave, β wave, α wave, θ wave, and δ wave (Table 1)

[0040]
[0041] In this case, the delta wave signal is extracted, judged according to the acquisition frequency, and finally the remote control of the treatment bed is realized.
