[0034] In modern home decoration design, there are often sharp or hard edges at the corners of furniture and walls. In order to prevent an object from accidentally colliding with the edge during movement and getting injured, an anti-collision buffer structure is often provided. However, the above structure can only reduce the injury suffered by the colliding object and cannot fully meet the needs of users. For example, when a child is collided or falls, although the injury suffered by the child is reduced to some extent, the guardian cannot know in time that the child is currently in a collision or fall.

[0035] Therefore, the present application proposes a collision reminder device and system, aiming to reduce the injury suffered by a child when colliding with a device to be protected and at the same time prompt the guardian of the occurrence of the collision event.

[0036] In an embodiment of the present application, referring to Figure 1 , the collision reminder device includes:

[0037] The fabric pressure detection component 10 is configured to be disposed on the surface of the device to be protected 50; the fabric pressure detection component 10 is configured to output a corresponding first voltage signal through its output terminal when being pressured itself.

[0038] The main control circuit 20 is electrically connected to the fabric pressure detection component 10.

[0039] Wherein, the collision reminder device further includes: a reminder component 30 and / or a communication module 40 for communicatingly connecting with an external terminal, and both the reminder component 20 and the communication module 40 are electrically connected to the main control circuit 20.

[0040] The main control circuit 20 is configured to determine that the fabric pressure detection component 10 is collided according to the first voltage signal, and control the reminder component 30 to give a reminder and / or output a collision reminder signal to the external terminal through the communication module 40.

[0041] In this embodiment, the working mechanism of the fabric pressure detection component 10 is realized by utilizing the sensing characteristics of the deformation material it has. When an external pressure is applied to the fabric pressure detection component 10, the size and shape of the deformation material will change, thereby generating different physical parameters such as resistance, capacitance, and inductance. These physical parameters can be measured and converted by a control circuit to obtain information about the external pressure. Optionally, the fabric pressure detection component 10 can be implemented by a capacitive pressure sensor. Multiple capacitive pressure sensors can be combined with the fabric through specific processes (such as sewing, pasting, thermal bonding, etc.). When the fabric is pressed, the capacitive pressure sensor at the pressed position outputs a first voltage signal to the main control circuit 20. The capacitive pressure sensor can be implemented by a graphene-based flexible capacitive pressure sensor or a thin-film capacitive pressure sensor. When the fabric is pressed, the graphene of the graphene-based flexible capacitive pressure sensor deforms, thereby causing a change in its electrical conductivity, so that the voltage of the first voltage signal becomes smaller. Or, the thin film (movable electrode) of the thin-film capacitive pressure sensor deforms, thereby changing the distance between it and the fixed electrode. The change in distance will cause a change in the capacitance value, and the voltage magnitude of the first voltage signal also changes accordingly. In addition, since the fabric has a certain flexibility and elasticity, when a collision object collides with the surface of the device to be protected 50, the fabric can play a certain buffering role, thereby reducing the direct damage caused by the surface of the device to be protected 50 to the collision object.

[0042] Optionally, the fabric pressure detection component 10 can be implemented by a voltage division circuit composed of a fabric resistive pressure sensor and a voltage dividing resistor. Refer to Figure 2, one end of the voltage-dividing resistor is grounded, and the other end is electrically connected to one end of the fabric resistive pressure sensor. The other end of the fabric resistive pressure sensor is connected to a voltage, and the main control circuit 20 is electrically connected to the first end of the voltage-dividing resistor. The fabric resistive pressure sensor includes at least two mutually wound pressure-sensing yarns. The first end of the pressure-sensing yarn is connected to the power supply terminal, and the second end of the pressure-sensing yarn is grounded. When the user reaches out and presses, the pressed parts of the two pressure-sensing yarns squeeze each other and deform, so that the resistance values of the two pressure-sensing yarns change, decreasing from the megaohm level to the hundred-ohm level. The greater the pressure on the pressure-sensing yarn, the smaller the resistance value. Correspondingly, the voltage of the pressure-sensing yarn also decreases. Since the pressure-sensing yarn has a certain flexibility and elasticity, the fabric pressure detection component 10 is equivalent to the fabric and also has a certain flexibility and elasticity. When the collision object collides with the device 50 to be protected, the fabric resistive pressure sensor can play a certain buffering role, thereby reducing the direct damage caused by the impact force to the collision object. Among them, the pressure-sensing yarn includes but is not limited to various types of yarns with pressure-sensing functions such as carbon nanotube fiber yarns.

[0043] In this embodiment, the main control circuit 20 determines whether the fabric pressure detection component 10 has been collided according to the magnitude of the first voltage signal. Based on the above-described embodiment of the voltage division circuit composed of the fabric resistive pressure sensor and the voltage division resistor, the voltage of the voltage division resistor is the voltage of the first voltage signal. When the fabric resistive pressure sensor is not under pressure, the resistance of the fabric resistive pressure sensor is relatively large, so that the voltage of the voltage division resistor is relatively small. The main control circuit 20 can be set to determine that the fabric pressure detection component 10 has not been collided when it detects that the voltage of the first voltage signal is less than the preset voltage value. When the fabric resistive pressure sensor is collided, the resistance value of the fabric resistive pressure sensor decreases, so that the voltage of the voltage division resistor rises. The main control circuit 20 determines that the fabric pressure detection component 10 has been collided when the voltage of the first voltage signal rises to the preset voltage value. Further, the main control circuit 20 can also determine the collision situation of the fabric pressure detection component 10 according to the magnitude of the first voltage signal. When the collision pressure on the fabric resistive pressure sensor is relatively heavy, the resistance value of the fabric resistive pressure sensor is extremely small, so that the voltage of the voltage division resistor is extremely large. The main control circuit 20 can determine that the fabric pressure detection component 10 has been severely collided when the voltage of the first voltage signal is greater than or equal to the first preset voltage. When the collision pressure on the fabric resistive pressure sensor is relatively light, the resistance value of the fabric resistive pressure sensor is relatively small, so that the voltage of the voltage division resistor is relatively large. The main control circuit 20 can determine that the fabric pressure detection component 10 has been slightly collided when the voltage of the first voltage signal is less than the first preset voltage and greater than or equal to the second preset voltage. With such a setting, in practical applications, the user can determine the collision situation of the collided object according to the prompt of the prompt component 30 and / or the collision reminder signal received by the external terminal, and the user can take corresponding measures according to the collision situation.

[0044] In this embodiment, the main control circuit 20 can be implemented by using a main controller, such as an MCU (Microcontroller Unit, micro control unit), a DSP (Digital Signal Process, digital signal processing chip), an FPGA (Field Programmable Gate Array, programmable logic gate array chip), an SOC (System On Chip, system-level chip), etc. The main control circuit 20 has an ADC interface electrically connected to the fabric pressure detection component 10, and the ADC interface is used to collect the first voltage signal of the fabric pressure detection component 10.

[0045] In this embodiment, when the collision reminder device includes a communication module 40, optionally, the communication module 40 includes a wired communication module. Among them, the wired communication module can use a wired communication chip, such as a CAN communication chip, an SPI communication chip, an I2C communication chip, a LIN communication chip, etc. The wired communication module 40 establishes a communication connection with the host computer via a communication line. When the main control circuit 20 determines that the woven fabric pressure detection component 10 has been collided, a collision reminder signal is output to the host computer via the wired communication module 40. After processing the collision reminder signal, the host computer sends a corresponding communication signal to an external terminal. Optionally, the communication module 40 includes a wireless communication module. Among them, the wireless communication module can use a wireless communication chip, such as a 4G / 5G communication chip, a WIFI communication chip, a Bluetooth communication chip, a local area network communication chip, etc. The wireless communication chip can establish a communication connection with the external terminal via an antenna and a wireless communication network. For example, when the external terminal is a user's handheld terminal, the wireless communication chip establishes a wireless communication connection with the user's handheld terminal via a 4G / 5G network. When the main control circuit 20 determines that the woven fabric pressure detection component 10 has been collided, a collision reminder signal is sent to the external terminal via the wireless communication module.

[0046] In this embodiment, when the collision reminder device includes a reminder component 30, the reminder component 30 includes a sound reminder component 30 and / or a light reminder component 30. The sound reminder component 30 can be implemented by a voice alarm module. When the main control circuit 20 determines that the woven fabric pressure detection component 10 has been collided, a corresponding voice alarm is issued. The light reminder component 30 can be implemented by a flash light. When the main control circuit 20 determines that the woven fabric pressure detection component 10 has been collided, the flash light is controlled to flash quickly to ensure that attention can be attracted even in a noisy environment.

[0047] It can be understood that the collision reminder device can include both the above reminder component 30 and the communication module 40 at the same time, or can include only one of them.

[0048] In this embodiment, referring to Figure 3 , the woven fabric pressure detection component 10 is laid or attached to the surface of the device to be protected 50. The device to be protected 50 includes objects with corners in the home, such as furniture with corners like tables or chairs, or corners such as wall corners or staircase corners. By reasonably arranging the woven fabric pressure detection component 10 in the entire home environment, the risk of the collision object being injured due to collision can be effectively reduced.

[0049] The collision reminder device of the present application includes a fabric pressure detection component 10, which is used to be arranged on the surface of the device to be protected 50; the fabric pressure detection component 10 is used to output a corresponding first voltage signal through its own output terminal when it is under pressure; a main control circuit 20, the main control circuit 20 is electrically connected to the fabric pressure detection component 10; wherein, the collision reminder device further includes: a reminder component 30 and / or a communication module 40 for communicating with an external terminal, both the reminder component 30 and the communication module 40 are electrically connected to the main control circuit 20; the main control circuit 20 is used to determine that when the fabric pressure detection component 10 is collided according to the first voltage signal, control the reminder component 30 to give a reminder and / or output a collision reminder signal to the external terminal through the communication module 40. With such a setting, in practical applications, since the fabric pressure detection component 10 has a certain softness and elasticity, when a collision object collides with the surface of the device to be protected 50, it can play a certain buffering role to reduce the direct harm of the impact force to the collision object. And the collision reminder device of the present application also controls the reminder component 30 to give a reminder when it detects that the surface of the device to be protected 50 is collided, or transmits a corresponding communication signal to the external terminal, such as the user's mobile phone, through the communication module 40, to remind the user that the collision object may collide with the surface of the device to be protected 50, so that the user can timely confirm the situation of the collision object and take corresponding solutions, thereby avoiding the injury of the collision object from getting worse due to failure to be treated in time after colliding with the device to be protected 50.

[0050] In an embodiment of the present application, with reference to Figure 4 , the collision reminder device further includes:

[0051] a distance detection module 60, which is used to detect the distance between the collision object and the target object and output a corresponding distance detection signal; wherein, the main control circuit 20 is used to determine the first distance between the collision object and the target object according to the distance detection signal; the collision object is the object that collides with the fabric pressure detection component 10.

[0052] Optionally, in order to simplify the control logic and streamline the circuit architecture in the collision reminder device. In an embodiment, the collision reminder device of the present application defaults that the collision object and itself are in the same position, that is, detecting the distance between the collision object and the target object is detecting the distance between the collision reminder device itself and the target object. In an example, the target object can be the guardian of the collision object. For example, if the collision object is a child and the target object is an adult, the collision reminder device of the present application defaults that the child and itself are in the same position. At this time, the distance between the child and the guardian is the same as the distance between the collision reminder device of the present application and the guardian. Therefore, the collision reminder device of the present application only needs to detect the distance between itself and the guardian to determine the distance between the child and the guardian.

[0053] In this embodiment, the ranging methods of the distance detection module 60 include multiple methods. Optionally, the distance detection module 60 is the communication module 40 of the collision reminder device of the present application, or another communication module 40 electrically connected to the main control circuit 20. The communication module 40 is used to obtain the positioning data of the external terminal held by the target object, and the main control circuit 20 calculates and determines the distance based on the positioning data of the collision reminder device itself and the positioning data of the external terminal held by the target object.

[0054] Optionally, the distance detection module 60 is a plurality of camera modules arranged in a home environment. The main control circuit 20 is used to determine the corresponding position of the target object in the home environment according to the image information obtained by the plurality of camera modules, and then determine the distance according to the home environment position-distance parameter set by the user. It can be understood that in this embodiment, if the target object is not found in the home environment, it can be directly determined that the current target object is far from the collision object, and the corresponding prompting process can be implemented in the manner of the following embodiment.

[0055] Optionally, the distance detection module 60 is the communication module 40 of the collision reminder device of the present application, or another communication module electrically connected to the main control circuit 20. When the communication module 40 and the external terminal held by the target object are based on the same wireless communication network, the main control circuit 20 determines the distance between itself and the target object according to the signal strength of the communication signal sent by the external terminal obtained by the communication module 40. It can be understood that if the communication module 40 and the external terminal do not communicate based on the same network. For example, in a WIFI environment, the signal sent by the external terminal is sent by the gateway component in the home, rather than directly sent through the same WIFI communication network. In this case, it can be directly determined that the current target object is far from the collision object, and the corresponding prompting process can be implemented in the manner of the following embodiment.

[0056] Optionally, in another embodiment, in order to ensure the accuracy of distance detection, the collision object is a user who causes a collision impact on the fabric pressure detection component 10, such as a child, an elderly person, etc. The target object can be the guardian of the collision object;

[0057] Optionally, the smart terminals on the child are respectively established with communication connections with the external terminal held by the guardian and the communication module 40. The smart terminal obtains the positioning information of the external terminal, and calculates the distance between the child and the guardian according to its own positioning information and the positioning information of the external terminal. The smart terminal outputs a corresponding signal to the main control circuit 20 through the communication module 40 according to the determined distance, so that the main control circuit 20 obtains the distance between the child and the guardian.

[0058] Optionally, when the smart terminal on the child and the external terminal held by the guardian are based on the same wireless communication network, the smart terminal establishes a communication connection with the communication module 40. The smart terminal determines the distance between itself and the target object according to the signal strength of the communication signal sent by the external terminal, and outputs a corresponding signal to the main control circuit 20 through the communication module 40 according to the determined distance, so that the main control circuit 20 obtains the distance between the child and the guardian. It can be understood that if the smart terminal and the external terminal do not communicate based on the same network, for example, in a WIFI environment, the signal sent by the external terminal is sent by the gateway component in the home, rather than directly sent through the same WIFI communication network. In this case, it can be directly determined that the current child is far from the guardian, and the corresponding prompt process can be implemented in the manner of the following embodiments.

[0059] Based on the above embodiments, the main control circuit 20 is configured to control the prompt component 30 to give a prompt and / or output a collision reminder signal to the external terminal through the communication module 40 when it is determined according to the first voltage signal that the fabric pressure detection component 10 is collided and it is determined according to the distance detection signal that the first distance is greater than or equal to the first preset distance; and / or,

[0060] The main control circuit 20 is configured to output a collision reminder signal to the external terminal through the communication module 40 when it is determined according to the first voltage signal that the fabric pressure detection component 10 is collided and it is determined according to the distance detection signal that the first distance is less than the first preset distance. For example, the collision object is a child and the target object is a guardian. Since the guardian can discover whether the child is collided in the first time when the distance between the child and the guardian is relatively close, the collision reminder device of the present application does not give a prompt when it is determined that the fabric pressure detection component 10 is collided, so as to avoid unnecessary interference caused by prompt actions such as light flashing or alarm sound or excessive information received by the external terminal; it can be understood that even if the distance between the child and the guardian is relatively close, the guardian may be looking at the mobile phone and not notice the situation of the child. In this regard, the collision reminder device of the present application outputs a collision reminder signal to the external terminal through the communication module 40 when it is determined that the fabric pressure detection component 10 is collided, so as to prompt the guardian of the occurrence of the collision event.

[0061] Since the guardian cannot discover the collision event in the first time when the distance between the child and the guardian is relatively far, the collision reminder device of the present application controls the prompt component 30 to give a prompt or outputs a collision reminder signal to the external terminal through the communication module 40 when it is determined that the fabric pressure detection component 10 is collided and the first distance is greater than or equal to the first preset distance, so as to attract the attention of the guardian and ensure that the guardian can discover the collision event in time. Through the above settings, the collision reminder device of the present application can ensure that the guardian discovers the collision event in time while avoiding unnecessary interference.

[0062] In an optional embodiment, the collision reminder device includes a reminder component 30. The working modes of the reminder component 30 include a standard mode and an emergency mode. The main control circuit 20 is configured to determine that the woven fabric pressure detection component 10 is collided according to the first voltage signal, and when it is determined according to the distance detection signal that the first distance is less than the first preset distance, control the reminder component 30 to work in the standard mode; the main control circuit 20 is configured to determine that the woven fabric pressure detection component 10 is collided according to the first voltage signal, and when it is determined according to the distance detection signal that the first distance is greater than or equal to the first preset distance, control the reminder component 30 to work in the emergency mode. For example, the reminder component 30 is an acoustic alarm module. Since the distance between the child and the guardian is relatively close, both the guardian and the child are at home, so the distance between the guardian and the acoustic alarm module is also relatively close. In this case, when the collision reminder device of the present application determines that the woven fabric pressure detection component 10 is collided and the first distance is less than the first preset distance, it controls the acoustic alarm module to emit an alarm sound with a relatively low volume to gently remind the guardian and avoid disturbing the guardian and the child with an overly loud alarm sound. Since the distance between the child and the guardian is relatively far and the guardian is outdoors, the guardian cannot discover the collision event in the first place when the child has a collision. In this case, when the collision reminder device of the present application determines that the woven fabric pressure detection component 10 is collided and the first distance is greater than or equal to the first preset distance, it controls the acoustic alarm module to emit an alarm sound with a relatively high volume to attract the attention of the guardian or the surrounding people and ensure that the guardian or others can discover the collision event in time.

[0063] Through the above settings, the collision reminder device of the present application adjusts the working mode of the reminder component 30 according to the distance between the collision object and the target object, so as to ensure that the guardian can discover the collision event in time while avoiding unnecessary interference, and improve the user experience of the guardian.

[0064] In an optional embodiment, the collision reminder device includes a communication module 40. The main control circuit 20 is configured to determine that the fabric pressure detection component 10 has been collided according to the first voltage signal, and when it is determined according to the distance detection signal that the first distance is less than the first preset distance, output a collision reminder signal to an external terminal through the communication module 40; the main control circuit 20 is configured to determine that the fabric pressure detection component 10 has been collided according to the first voltage signal, and when it is determined according to the distance detection signal that the first distance is greater than or equal to the first preset distance, continuously output a collision reminder signal to the external terminal through the communication module 40. When the main control circuit 20 receives an acknowledgment signal sent by the external terminal through the communication module 40, it stops outputting the collision reminder signal. For example, when the distance between a child and a guardian is relatively close, the guardian can discover the collision event in a timely manner, or can discover the collision reminder signal received by the external terminal in a timely manner. In this case, when the collision reminder device of the present application determines that the fabric pressure detection component 10 has been collided, it sends a single or a small number of collision reminder signals to the external terminal through the communication module 40 to avoid disturbing the guardian with excessive prompts. When the distance between the child and the guardian is relatively far, the guardian may be out working and unable to discover the collision event in a timely manner, or may not be able to discover the collision reminder signal received by the mobile phone in a timely manner due to being busy. In this case, when the collision reminder device of the present application determines that the fabric pressure detection component 10 has been collided, it continuously sends collision reminder signals to the guardian's mobile phone through the communication module 40 until the guardian confirms the collision event, ensuring that the guardian can discover the collision event. After the guardian confirms the collision event, for example, by clicking the confirmation button on the APP, the mobile phone then sends an acknowledgment signal to the collision reminder device of the present application to stop the output of the collision reminder signal and avoid disturbing the guardian with excessive prompts.

[0065] Through the above settings, the collision reminder device of the present application selects an appropriate reminder method through the communication module 40 according to the distance between the collision object and the target object, so as to ensure that the guardian can discover the collision event in a timely manner while avoiding unnecessary interference.

[0066] In an alternative embodiment, the collision reminder device includes a communication module 40 and a reminder component 30. The main control circuit 20 is configured to control the reminder component 30 to give a reminder when it is determined according to the first voltage signal that the fabric pressure detection component 10 has been collided and according to the distance detection signal that the first distance is less than the first preset distance; the main control circuit 20 is configured to output a collision reminder signal to an external terminal via the communication module 40 when it is determined according to the first voltage signal that the fabric pressure detection component 10 has been collided and according to the distance detection signal that the first distance is greater than or equal to the first preset distance. For example, since the distance between the guardian and the reminder component 30 is also relatively close when the distance between the guardian and the child is relatively close, when the reminder component 30 gives a reminder, such as emitting an audible alarm or flashing a light, the guardian can timely discover the reminder of the reminder component 30 and timely discover the collision event. Since the distance between the guardian and the child is relatively far, the guardian may be out and not at home, so the guardian cannot discover the reminder given by the reminder component 30. In this regard, the collision reminder device of the present application sends a collision reminder signal to the guardian's mobile phone when it is determined that the fabric pressure detection component 10 has been collided, ensuring that the guardian can also timely discover the collision event when out.

[0067] Through the above settings, the collision reminder device of the present application selects a reasonable reminder method according to the distance between the collision object and the target object, so as to ensure that the reminder information sent by the collision reminder device of the present application can be timely discovered in the case where the target object approaches or moves away from the collision object.

[0068] Furthermore, the collision reminder device further includes a plurality of cameras, the plurality of cameras are respectively arranged in a plurality of rooms, the plurality of cameras are all electrically connected to the main control circuit 20, the main control circuit 20 is configured to process the images obtained by the plurality of cameras, and when the main control circuit 20 determines that the collision object and the target object are on the same image according to the processing result, it is determined that the collision object and the target object are in the same room; when the main control circuit 20 determines that the collision object and the target object are not on the same image according to the processing result, it is determined that the collision object and the target object are not in the same room; when the main control circuit 20 determines according to the first voltage signal that the fabric pressure detection component 10 has been collided and determines according to the images obtained by the plurality of cameras that the collision object and the target object are not in the same room, it controls the reminder component 30 to give a reminder and / or outputs a collision reminder signal to an external terminal via the communication module 40.

[0069] With such a setting, in actual applications, when the guardian and the child are in the same room, the guardian can immediately find out whether the child has been collided. Therefore, when the collision reminder device of the present application determines that the woven fabric pressure detection component 10 has been collided and the guardian and the child are in the same room, no prompt is made, avoiding interference to the guardian caused by prompt actions such as sound alarms or flashing lights, or excessive information received by the mobile phone. When the guardian and the child are not in the same room, the guardian may be in another room or outdoors. In this case, the guardian cannot immediately find out whether the child has been collided. For this reason, when the collision reminder device of the present application determines that the woven fabric pressure detection component 10 has been collided and the guardian and the child are not in the same room, it controls the prompt component 30 to give a prompt and / or outputs a collision reminder signal to an external terminal through the communication module 40 to ensure that the guardian can promptly discover the collision event. Through the above setting, the collision reminder device of the present application selects a reasonable prompt method according to the distance between the collision object and the target object to ensure that the guardian can promptly discover the collision event while avoiding unnecessary interference.

[0070] It should be understood that when the woven fabric pressure detection component 10 is accidentally touched, for example, when the woven fabric pressure detection component 10 is set at the corner of a table, if an object on the table accidentally falls on the woven fabric pressure detection component 10 but the child is not close to the table, it will cause accidental touch. If the user receives a prompt generated by the accidental touch, it will cause unnecessary interference to the user.

[0071] For this reason, in one embodiment, the collision reminder device of the present application also detects whether the collision object is a living unit. For example, the collision object is identified by an infrared sensor or an infrared camera. When the thermal infrared rays emitted by the living unit are received, it is determined that the collision object is a living unit, such as a child or an elderly person. It can be understood that when the collision reminder device of the present application determines that the collision object is not a living unit, it does not control the prompt component 30 to give a prompt and / or output a collision reminder signal to an external terminal through the communication module 40.

[0072] In this embodiment, the distance detection module 60 can also detect the distance between the collision object and the fabric pressure detection component 10 to determine whether the fabric pressure detection component 10 collides with the collision object, where the target object is the fabric pressure detection component 10. In one embodiment, when the main control circuit 20 determines that the fabric pressure detection component 10 is collided according to the first voltage signal and determines that the first distance is less than the preset distance according to the distance detection signal, the main control circuit 20 controls the prompting component 30 to give a prompt and / or outputs a collision reminder signal to an external terminal through the communication module 40; when the main control circuit 20 determines that the fabric pressure detection component 10 is collided according to the first voltage signal and determines that the first distance is greater than the preset distance according to the distance detection signal, the main control circuit 20 controls the prompting component 30 to give a prompt and / or outputs a collision reminder signal to an external terminal through the communication module 40. For example, assuming that the collision object is a child, when the main control circuit 20 determines that the fabric pressure detection component 10 is collided according to the first voltage signal and determines that the first distance is greater than the preset distance according to the distance detection signal, it may be a false touch caused by the child hitting an object in his hand on the device to be protected 50 from a distance, rather than a real safety hazard. Therefore, the main control circuit 20 does not choose to control the prompting component 30 to give a prompt or output a collision reminder signal to an external terminal through the communication module 40 to avoid unnecessary false alarms. When the main control circuit 20 determines that the fabric pressure detection component 10 is collided according to the first voltage signal and determines that the first distance is less than the preset distance according to the distance detection signal, it may be that the child accidentally touches the device to be protected 50, such as a corner, when playing near the device to be protected 50, causing the fabric pressure detection component 10 to be collided. Therefore, the main control circuit 20 controls the prompting component 30 to give a prompt and / or outputs a collision reminder signal to an external terminal to timely prompt the guardian of the occurrence of the collision event and prevent potential safety hazards.

[0073] With the above settings, the collision reminder device of the present application is used to not give a prompt when it is determined that the fabric pressure detection component 10 and the distance between the fabric pressure detection component 10 and the collision object is far, so as to avoid unnecessary false alarms.

[0074] Further, when a child throws an object in their hand at the device to be protected 50 from a distance, the child may have a tendency to approach the device to be protected 50, increasing the risk of collision between the child and the device to be protected 50. In response to this, the collision reminder device of the present application may further include a camera. The camera is used to obtain images around the device to be protected 50. The main control circuit 20 is used to determine the distance between the collision object and the device to be protected 50 based on the images obtained by the camera. When the main control circuit 20 determines that the collision object has a tendency to approach the device to be protected 50 based on the images obtained by the camera, it controls the reminder component 30 to give a reminder and / or outputs a collision reminder signal to an external terminal via the communication module 40 to remind the guardian that the child is approaching the device to be protected 50, so that the guardian can take corresponding measures.

[0075] The present application also proposes a collision reminder system, including the collision reminder device as described above.

[0076] It should be noted that since the collision reminder system of the present application is based on the above-mentioned collision reminder device, the embodiments of the collision reminder system of the present application include all the technical solutions of all the embodiments of the above-mentioned collision reminder device, and the achieved technical effects are exactly the same, which will not be elaborated here.

[0077] In an embodiment of the present application, the number of the collision reminder devices is multiple, and the multiple fabric pressure detection components 10 are respectively arranged on the surfaces of the multiple devices to be protected 50 or on multiple surfaces of the device to be protected 50;

[0078] When the main control circuit 20 determines that the fabric pressure detection component 10 has been collided based on the first voltage signal, it outputs a collision reminder signal and the number information corresponding to the collision reminder device where it is located to an external terminal via the communication module 40.

[0079] In this embodiment, each collision reminder device has a unique number. The user arranges the multiple fabric pressure detection components 10 on the surfaces of the multiple devices to be protected 50 or on multiple surfaces of the device to be protected 50, and remarks the numbers of the multiple collision reminder devices on the APP of the mobile phone according to the names of the multiple devices to be protected 50 or the names of the multiple surfaces of the device to be protected 50. When any one of the fabric pressure detection components 10 is collided, a collision reminder signal and the number information corresponding to the collision reminder device where it is located are output to the mobile phone via the communication module 40. The user can know which fabric pressure detection component 10 has been collided or which part of the device to be protected 50 has been collided according to the remark corresponding to the number information, which helps the user to take corresponding measures according to the actual situation of the collision.

Any equivalent structural transformation made under the technical concept of the present application by using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
