As shown in Fig. 5 and Fig. 6, the body is installed on the wall through the fixing device 7 provided on the back of the body, and can also be fixed on the ground frame.

The above-mentioned processing terminal 4 includes a mainboard 41 with a built-in microprocessor and an output device electrically connected to the mainboard. The mainboard is connected with a mainboard temperature sensor 43, a photosensitive sensor 44, and a camera 45. A local interface 46 for implementing safety measures is provided on the mainboard.

The aforementioned safety controller is connected with a speed sensor for collecting speed, an acceleration sensor for collecting acceleration, a stroke sensor for obtaining stroke, and a safety control temperature sensor for monitoring temperature; Sensor 61.

Above-mentioned training parts are barbell bar, handle, and handle is A handle 101, B handle 104 and C handle 107, and stay rope is A stay rope 102, B stay rope 105 and C stay rope 108, and stay rope stroke sensor is A stay rope stroke Sensor 103, B stay cord travel sensor 106 and C stay cord travel sensor 109; said A handle 101 is connected to A stay cord travel sensor 103 and A stay cord speed sensor 110 through A stay cord 102, and said B handle 104 is connected to A stay cord travel sensor 103 and A stay cord speed sensor 110 through B The stay cord 105 is connected to the B stay cord travel sensor 106A and the B stay cord speed sensor 111, and the C handle 107 is connected to the C stay cord travel sensor 109 and the C stay cord speed sensor via the C stay cord 108 passing through the first swing arm 112 , the handle D is connected to the actuation point stroke sensor 113 and the actuation point speed sensor 114 through the D pull cord passing through the second swing arm.

In Embodiment 1, during speed monitoring, the user sets a pulling force of 30 kg and connects the C and D stay ropes to the barbell to perform bench press. Users may accidentally drop their hands and cause sports injuries, and speed monitoring can be used to reduce the risk of sports injuries. The speed sensor collects the speeds of the C rope and D rope at a certain frame rate (for example, 1/1000ms) and reports them to the security controller (MCU) in the computing device in real time.

Due to sweaty hands slipping during the training process and causing the barbell to drop, the resistance generating device (servo motor) returns to the rope with a pulling force of 30kg, a speed of 2m/s and an acceleration of 20m/ ^s2 . After the stroke of Δl1, the speed sensor collects that the pull rope recovery speed reaches the upper limit of the safety threshold, for example, the upper limit of the safety threshold is 4m/s.

The safety controller (MCU) sends commands (step adjustment resistance from 30 to 0kg) to the resistance generating device (servo motor) in real time, and at the same time implements the SUI that sends commands (danger warning) to the main board. After receiving the command, the SUI immediately processes the command, displays the danger interface (hands-off warning interface), plays the danger warning sound (alarm sound), and prompts safe operation guidance (the resistance generating device has unloaded to 0kg, and after the pull rope is returned to zero, you can Leave the scene and restart the device to exercise).

The resistance generating device (servo motor) immediately processes the command (30 to 0kg) after receiving the command, and after the stroke of Δl2, the command becomes effective, the resistance adjustment is completed, and the resistance generating device reports the completion status to the safety controller (MCU) for safety control The device reports the completion status of the resistance adjustment to the SUI. At this time, the barbell returns with the inertia of the initial velocity and acceleration, and performs free fall motion with a weight of 2kg and a speed of 4m/s.

In Example 2, when the acceleration is monitored, the user uses the handle to connect the pull rope through the connector, and then pulls the handle repeatedly and quickly. The user may use different forces to pull at different speeds, which is faster than normal training speed. For example, if the speed exceeds 1.5 times of the safe rope-out speed, the motor voltage may be too high and the physical equipment may be damaged due to long-term over-speed rotation. In order to avoid this situation, the safety controller (MCU) will increase the resistance generated by the resistance generating device (servo motor) on the basis of the current resistance based on the current speed after determining that the pulling rope is pulled out at a speed exceeding the safe range: The greater the speed, the greater the resistance. By dynamically changing the resistance against the user's pulling force, the purpose of reducing the speed at which the pull rope is pulled out is achieved.

The safety controller (MCU) sends an alarm code to the SUI of the main board, and immediately processes the command after receiving the command, displays the danger interface (pull out the overspeed warning interface), plays the danger warning sound (alarm sound), and prompts safe operation guidance (After the pull rope returns to zero, you can leave the scene and restart the exercise).

In Example 3, during temperature monitoring, the user set up a counterweight of 20 kg in a place with higher room temperature and continued to exercise for 2 hours. Under the combined effect of operation, the temperature of the motor itself will gradually increase, and working at a high temperature for a long time will reduce the service life of the resistance generating device (servo motor).

In order to avoid the above problems, the safety controller (MCU) will monitor the temperature of the resistance generating device (servo motor) in real time, and when it reaches the set safety threshold (for example, 80°C) and lasts for a period of time, it will send a command to SUI, SUI Immediately process the command after receiving the command, display the dangerous interface (servo motor temperature is too high interface), play the danger warning sound (alarm sound), and at the same time notify the safety controller (MCU) to adjust the resistance step to 0kg, prompting safe operation guidance (The force has been unloaded to 0kg, and the exercise can be restarted after the temperature of the servo motor is lowered) and then the screen is locked. After the safety controller (MCU) monitors that the temperature of the resistance generating device (servo motor) has been kept below a relatively low temperature (for example, 40°C) for a period of time, it sends a command to notify the SUI, and the SUI lights up the screen after receiving the command, and the device can restart. start using.

In embodiment 4, when the stroke is monitored, the user uses the training parts to continuously pull out the stay rope, because the length of the stay rope is limited, if the user continues to pull after being pulled out to the maximum stroke, the other end of the stay rope is connected Any resistance generating device (servo motor) will cause damage.

In order to avoid the above problems, after the calculation device receives the rope stroke information sent by the acquisition device, it calculates whether the stroke threshold (for example, 95% of the maximum stroke) has been reached, and sends a command to the safety controller (MCU) after exceeding the threshold to control the servo. The electric motor exerts force to make the resistance gradually increase from the set counterweight to the maximum resistance when the stroke is between the threshold and the maximum stroke, preventing the user from pulling the pull rope to the maximum stroke. At the same time, the SUI displays a warning interface (the drawstring is pulled out too long), and a warning sound (alarm sound) is played.

In embodiment 5, when the brightness is monitored, the user turns on the light and uses the equipment for training in a room without natural light, and is doing fitness exercises with his back to the equipment, such as lying on a fitness bench with a 20kg counterweight and using a barbell bench press. If the light suddenly and unexpectedly goes out during training, the user will be very nervous, and it is not safe to continue training in a dark environment. Because the user is also holding the barbell bar with 20kg counterweight at this time, and facing away from the equipment at the same time, it is inconvenient to break away from the training parts to operate the equipment and stop the current training.

At this time, the photosensitive sensor installed on the device detects that the brightness has changed greatly in a short period of time, and sends the brightness value to the computing device. The computing device performs calculations by comparing the value received last time, and finds that the brightness change ratio exceeds the set safety threshold. (For example, 70%), send a command to the SUI, and the SUI will process the command immediately after receiving the command, and notify the safety controller to adjust the counterweight step to 0kg, and at the same time, the training part can be slightly vibrated by the pull rope to remind the user that it has been executed Safety precautions. At this point, the user can easily remove the barbell, get off the bench, and stop training safely.

In embodiment 6, when using the local interface, it is the same as the training scene in embodiment 1. If the user needs to stop the training when the strength is insufficient during the bench press barbell, you can wear a bluetooth device on your hand or install it on the barbell. The button of the Bluetooth device sends instructions to the training host through Bluetooth; it can also be passed to the training host by speaking the set keywords and collected by a high-sensitivity microphone; The sound decibel collected by the Min microphone exceeds the set threshold; when the user's heart rate exceeds the normal value during training, the heart rate collection device worn by the user can transmit the value to the training host through the local interface Bluetooth. When the user performs leg training, if he feels that the set resistance is too high and there is a risk of strain, he can use both hands to click the safety button provided by the human-computer interaction program running on the display at any time. After receiving the above instructions, the training host can adjust the resistance to 0kg step by step to prevent sports injuries.

In Embodiment 7, when using the remote interface, the user and the coach using another training host at the remote end use the human-computer interaction program on the training host to connect through the Internet, such as video calls or audio calls. Under the guidance of strength training. During the video call, the user may be injured due to non-standard movements during the training process. At this time, the coach at the remote end can guide at any time, and can also send network commands to the user through the human-computer interaction program on the coach’s training host in time. The remote interface provided by the human-computer interaction program on the equipment side can help the user adjust the resistance to 0kg to prevent injury; even if it is a voice call, when the user is not strong enough to operate the equipment during the training process, the user can inform the coach in time. It can be the same as the above operation, or the set keywords can be spoken through the remote voice and transmitted to the remote interface provided by the human-computer interaction program on the user's device side through the network to help the user adjust the resistance in time to prevent sports injuries.
