Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flow chart of a step counting method according to the present invention. As shown in fig. 1, the step counting method according to the embodiment of the present invention includes the following steps:
and S100, detecting whether the distance between the legs of the user is changed according to a preset rule.
That is to say, currently, wearable devices with a step counting function in the market measure the number of steps through an inertial sensor, such as an acceleration sensor or a gyroscope, and as long as the hand shaking times are large or the wearable devices are in a bumpy environment, the value of the step counter is increased, which is inaccurate because the user does not actually move. The invention directly monitors the activities of the two legs and determines that the user counts only when walking.
Specifically, the distance between the two legs is monitored, and the distance change is compared with a preset rule by utilizing the periodic change of the distance between the two legs when people walk, so that a counting result is obtained.
In one implementation, the step counting device comprises a hall sensor for fixing on one leg of the user, and a magnet for fixing on the other leg of the user; the magnet and the Hall sensor are mutually matched, and the fixed positions of the magnet and the Hall sensor correspond to each other.
Specifically, the step counter of the present invention includes: the device comprises a signal acquisition module, a signal processing module and an information display module. Specifically, the power supply device comprises a magnet, a low-power-consumption Hall sensor and a low-power-consumption main control CPU, and further comprises a power supply module. The magnet and other parts are arranged in a separable mode, and the Hall sensor, the main control CPU and the power supply module are integrally arranged to form a step counting device body. That is, the invention uses the periodic variation of the distance between the two legs when the person walks, and detects the variation of the distance between the two legs through the Hall sensor to count the steps. The Hall sensor is used as a magnetic control switch, and a circuit controlled by the Hall sensor is instantly conducted every time when the magnet is close to the Hall sensor and is disconnected when the magnet is far away from the Hall sensor.
Therefore, when the user uses the stepping device, the magnet is fixedly arranged on one leg, and the Hall sensor is fixedly arranged on the other leg, namely, the stepping device body where the Hall sensor is arranged is fixedly arranged on the other leg. It should be understood that the installation positions of the magnet and the hall sensor need to be the same, for example, the magnet and the hall sensor are installed at the knee parts or other parts of the legs, as long as the distance of the user when the legs cross can be ensured to be capable of conducting the circuit, and the distance of the user when the legs are stepped off can be capable of breaking the circuit. It can be understood that the fixed mounting position of the magnet and the hall sensor is not too high, for example, the fixed mounting position is higher than the knee position, and since the part of the person who walks away is below the knee and above the knee, the distance between the two legs is not too large, the magnet and the hall sensor can be always conducted, and the judgment and statistics of the step number are affected.
In a further implementation manner, the step S100 further includes, before the step S:
and step S10, presetting the distance threshold range of the Hall sensor and the magnet conduction circuit.
That is, the hall sensor and the magnet can conduct the circuit only within a distance threshold range. Therefore, the distance between the two legs does not need to be directly measured, the distance between the Hall sensor and the magnet does not need to be measured, only the circuit needs to be detected whether to be conducted or not, the detection is very convenient, and the detection efficiency is improved.
In a further implementation manner, the step S100 is specifically: detecting whether the distance between the legs of the user is reduced to be within the distance threshold range.
Specifically, when the user walks, the distance between the two legs decreases every time the two legs cross; when the two legs are stepped off, the distance between the two legs is increased. That is, the preset rule of the present invention means that the two legs are crossed once, the distance between the two legs is decreased, the two legs are stepped, and the distance between the two legs is increased. If the preset rule is met, the user can be judged to actually walk, and the number of steps can be calculated.
In further implementation manners, the step of "detecting whether the distance between the legs of the user decreases to be within the distance threshold" is specifically: and detecting whether a circuit is conducted between the Hall sensor and the magnet.
That is, the invention does not need to directly measure the distance between the two legs, does not need to measure the distance between the Hall sensor and the magnet, and only needs to detect whether the circuit is conducted between the Hall sensor and the magnet, thereby being very convenient and improving the detection efficiency.
The step S100 is followed by: and step S200, if the distance between the two legs of the user is changed according to a preset rule, counting the steps once.
That is, if the predetermined rule is satisfied, it can be determined that the user actually walks, and the number of steps can be calculated.
In an implementation manner, referring to fig. 2, the step S200 specifically includes:
step S210, when the circuit is conducted between the Hall sensor and the magnet, the electric potential of the circuit is changed from low to high, and a rising edge is generated;
and step S220, counting the step once when the rising edge is detected, and controlling the value of the counter to be increased by 1.
That is to say, the invention can control the on-off of the circuit by changing the distance between the magnet and the Hall sensor, the counter controlled by the magnet and the Hall sensor is respectively arranged on the two legs of the person, the distance between the two legs is reduced when the two legs are crossed once, the circuit is conducted, the potential is changed from low to high, and the counter is triggered by the rising edge to add 1.
In one implementation, after the step of detecting whether the circuit is turned on between the hall sensor and the magnet, the method further includes:
and when the Hall sensor and the magnet are not provided with a conducting circuit, the value of the counter is kept unchanged.
That is to say, when the legs of the user are in the stepping-on state, the step is not counted, and only one step is counted when the legs are crossed, so that the step is recorded only when the legs of the user are crossed once, and the step counting accuracy is improved. It can be understood that no matter the user shakes his hands or sits on a bumpy car, the wrong step counting is not performed, and the misjudgment is avoided.
In a further implementation, the step counting method further includes:
if the distance between the two legs of the user is increased to exceed the distance threshold range, a circuit is disconnected between the Hall sensor and the magnet, and a falling edge is generated;
when the falling edge is detected, the value of the counter is kept unchanged.
That is, as the user steps further, the distance between the legs increases, the circuit opens and the counter value remains unchanged.
The main program of the invention firstly initializes the system resource of the low-power CPU, then initializes the Hall sensor, the display module and the pedometer of the step-counting device, the low-power CPU detects the OUT output of the Hall sensor through the interrupt pin, if the CPU detects a rising edge, the pedometer carries OUT the 1-adding processing, and finishes the data acquisition, processing and display.
Referring to fig. 3, the step counting device body includes: power module 10, hall sensor 20, low-power consumption master control CPU30, in addition, for the step number of convenient display pedometer, still be provided with display module, for example, OLED display screen 40, make things convenient for the user to look over current step number at any time.

In addition, the step counting device body is connected with a terminal of a user in a communication mode, and the terminal can be a watch, a bracelet and other wearable devices and also can be a smart phone. The step counting device body can send the numerical value of the counter to a display screen on the user terminal for displaying. When a user wants to know the current step number, the user only needs to operate the terminal and obtains the numerical value of the counter on the step counting device through the terminal, and the method is very convenient. Therefore, a display module on the step counting device, namely an OLED display screen, can be omitted, and the production cost of the step counting device is saved.

Further, the memory 20 may also include both an internal storage unit of the step counting device and an external storage device. The memory 20 is used for storing application software installed in the step counting device and various types of data, such as program codes for installing the step counting device. The memory 20 may also be used to temporarily store data that has been output or is to be output. In one embodiment, the memory 20 stores a step counting program 30, and the step counting program 30 can be executed by the processor 10 to implement the step counting method of the present application.

and if the distance between the two legs of the user is changed according to a preset rule, counting the steps once.
That is to say, currently, wearable devices with a step counting function in the market measure the number of steps through an inertial sensor, such as an acceleration sensor or a gyroscope, and as long as the hand shaking times are large or the wearable devices are in a bumpy environment, the value of the step counter is increased, which is inaccurate because the user does not actually move. The invention directly monitors the activities of the two legs and determines that the user counts only when walking. If the user's walking is in accordance with the preset rule, the user can be determined to actually walk, and the number of steps can be calculated.
Specifically, the distance between the two legs is monitored, and the distance change is compared with a preset rule by utilizing the periodic change of the distance between the two legs when people walk, so that a counting result is obtained.

The magnet and other parts are arranged in a separable mode, and the Hall sensor, the main control CPU and the power supply module are integrally arranged to form a step counting device body. That is, the invention uses the periodic variation of the distance between the two legs when the person walks, and detects the variation of the distance between the two legs through the Hall sensor to count the steps. The Hall sensor is used as a magnetic control switch, and a circuit controlled by the Hall sensor is instantly conducted every time when the magnet is close to the Hall sensor and is disconnected when the magnet is far away from the Hall sensor.
Therefore, when the user uses the stepping device, the magnet is fixedly arranged on one leg, and the Hall sensor is fixedly arranged on the other leg, namely, the stepping device body where the Hall sensor is arranged is fixedly arranged on the other leg. It should be understood that the installation positions of the magnet and the hall sensor need to be the same, for example, the magnet and the hall sensor are installed at the knee parts or other parts of the legs, as long as the distance of the user when the legs cross can be ensured to be capable of conducting the circuit, and the distance of the user when the legs are stepped off can be capable of breaking the circuit. It can be understood that the fixed mounting position of the magnet and the hall sensor is not too high, for example, the fixed mounting position is higher than the knee position, and since the part of the person who walks away is below the knee and above the knee, the distance between the two legs is not too large, the magnet and the hall sensor can be always conducted, and the judgment and statistics of the step number are affected.
