detailed description

Fig. 1 is a schematic flow chart of Embodiment 1 of the control method of the cart provided by the present invention, the execution body of the method may be the control device of the cart, and the device is applied to the cart, specifically, it may be installed on the cart, Can be installed on other external devices, as shown in Figure 1, the method includes:

S101. Acquire the current speed of the cart.

Specifically, the control device of the cart can obtain the current speed of the cart through the speed sensors on the wheels of the cart, that is, the current speed of the cart can be measured by the speed sensor and transmitted to the control device of the cart.

S102. If the current speed of the cart is greater than zero, acquire the pressure value of the handle of the cart.

If the current speed of the cart is greater than zero, it means that the cart is running. At this time, you can further determine whether someone is controlling the cart by collecting the pressure value of the handle. If someone is controlling the cart and will hold the handle of the cart with their hands, then the pressure value of the handle is greater than the preset pressure value.

Specifically, the pressure value of the handle can be obtained through a gravity sensor or a pressure sensor. After the gravity sensor or the pressure sensor measures the pressure value of the handle, it can be transmitted to the control device of the cart.

S103. If the above pressure value is less than the preset pressure value, generate a reminder message.

If the pressure value is less than the preset pressure value, it indicates that the cart is running and no one is controlling it. At this time, a reminder message is generated so that the user can pay attention to the cart in time according to the reminder message to avoid danger.

There are many ways to generate reminder messages, such as vibrating, ringing, and pushing messages to the user's mobile phone, etc., which are not limited here.

In this embodiment, the current speed of the cart is obtained through collection. If the current speed of the cart is greater than zero, the pressure value of the handle of the cart is collected and obtained. When the pressure value is less than the preset pressure value, a reminder is generated. message to remind the user to pay attention to the cart, and realize that when no one is holding the cart and the cart moves, a reminder message is generated so that the user can pay attention to the cart in time according to the reminder message to avoid danger.

On the basis of the above embodiments, the gravity sensing value of the seat on the cart can also be collected. To further determine whether there is a child in the car, if the gravity sensing value is greater than the preset gravity sensing value, it means that there is a child.

If the above-mentioned pressure value is less than the preset pressure value, then generating a reminder message may be: if the above-mentioned pressure value is less than the preset pressure value, and the gravity sensing value is greater than the preset gravity sensing value, generating a reminder message.

The current speed of the cart is greater than zero, indicating that the cart is running. Further, the above-mentioned pressure value is less than the preset pressure value, indicating that no one is controlling the cart. In this embodiment, it is also considered whether there are children in the cart. When it is greater than the preset gravity sensing value, it indicates that there is a child in the cart, and a reminder message is generated to avoid danger. If there is no child in the stroller, the reminder message may not be generated to save resources.

Further, after the reminder message is generated, it can be notified to the user in various ways:

In one manner, the above-mentioned reminder message is sent to the mobile terminal. It may be by binding with the corresponding application program on the mobile terminal to send the reminder message to the corresponding application program; or by sending the reminder message to the operator side to request the operator to send a text message or make a call to the mobile terminal Or, send the reminder message to the mobile terminal synchronously through the Bluetooth function; or, send the reminder message to the mobile terminal through Near Field Communication (NFC for short), which is not limited here. After receiving the reminder message, the mobile terminal can ring, vibrate, etc. according to preset settings.

In the specific implementation process, different reminder methods can also be set according to the distance between the cart and the mobile terminal. Optionally, after the mobile terminal receives the reminder message, it can obtain the distance between the cart and the mobile terminal, and For example, vibrate within 20 centimeters, music rings when the distance is 20-50 centimeters, and alarm sounds when the distance is more than 50 centimeters, but not limited thereto. So that the user can respond in time after receiving the reminder message to avoid danger.

The mobile terminal may be a mobile phone, a tablet computer, and the like.

In another way, the reminder message is used to trigger the alarm device to alarm, that is, the alarm device can be installed on the cart, and the above-mentioned reminder message triggers the alarm device to alarm, which can be specifically an alarm sound, etc., which is not limited here. So that the user can respond in time according to the alarm of the alarm device to avoid danger. Specifically, different alarm sound volumes may also be set according to the distance between the cart and the mobile terminal, for example, the greater the distance, the greater the alarm sound volume, etc., but it is not limited thereto.

Further, the user may not notice the reminder message, in order to avoid danger, after the reminder message is generated, the brake may be triggered to control the driving speed of the cart.

Specifically, the brake may be activated to reduce the speed of the cart until the cart stops moving. Wherein, the brake can be installed on the wheel of the cart, or be connected with the brake part of the cart, so as to reduce the traveling speed of the cart under the control of the control device of the cart.

On the basis of the above-mentioned embodiments, in the process of using the cart, it may be in places with high light intensity, such as outdoors with sufficient sunlight, or places such as shopping malls with high light intensity. For children's vision, in order to avoid the influence of strong light on children, when the adult pushes the cart, that is, when the above-mentioned pressure value is greater than the preset pressure value, the light intensity is collected. If the light intensity is greater than the preset light intensity, Then control the shading part of cart to open. Specifically, the light intensity can be measured by the light sensor, and then transmitted to the control device of the cart, so that the control device of the cart controls the opening of the shading part of the cart when the light intensity is greater than a preset light intensity.

The shading component may be a cloth curtain, a shading board, etc., which is not limited here.

According to the above description, it can be known that on the basis of the existing cart, a pressure sensor can be installed on the handle of the cart to obtain the pressure value of the handle. Further, a gravity sensor can be installed on the seat of the stroller to obtain the gravity sensing value of the seat. Alarm equipment can also be installed. In addition, brakes can be provided on the wheels of the cart.

In the specific implementation process, these pressure sensors, gravity sensors, alarm equipment, brakes, light induction sensors, and light-shielding components are all connected to the control device of the cart through the communication interface. Specifically, it can be a wireless communication connection, or it can be is a wired communication connection. These devices are all controlled by the control device of the cart, and report the data obtained by themselves, such as pressure value, gravity value, etc., to the control device of the cart.
