Description

Intelligent sensing device and using method thereof

The present disclosure relates to an intelligent sensing device, and more particularly to an intelligent sensing device for determining whether a user is safe.

As the development of society and technology continues to advance, the safety issues of pedestrians walking on the road increase. For example, today's young people like to wear full-face headphones to walk on the road, but full-cover headphones make it easy for pedestrians to reduce sensitivity to surrounding things, and it is easy to be dangerous because of negligence. On the other hand, with the development of transportation, vehicles such as locomotives, when driving on the road, may overlook the potential dangers of the surrounding because of poor mentality.

There are visual dead ends on the sides, sides and front of the human eye, and there are visual defects. Therefore, it is everyone's self-risk on the road, everyone is careful. Although similar devices have been introduced today, such as reversing radars, they are only deployed on vehicles and only at the rear. There is not enough reminder for the nearby objects or the human body.

Therefore, how to provide a relationship that can actively remind pedestrians and objects, such as too close or relatively high speed, to remind pedestrians to make corresponding avoidance actions, and to increase the safety of people themselves, is currently A topic that is highly valued and sought to be solved.

FIG. 1 is a block diagram of an intelligent sensing device according to some embodiments of the present disclosure. FIG. 2 is a block diagram of a sensing module of the smart sensing device according to some embodiments of the present disclosure. FIG. 3 is a block diagram of a prompting module of the smart sensing device according to some embodiments of the present disclosure. The smart sensing device 10 has a sensing module 110, a positioning module 120, a memory 130, a processor 140, and a prompting module 150. Each of the above is electrically connected to each other to provide electrical signals and data transmission.

In addition, the smart sensing device 10 further has a power module (not shown). In some embodiments, for example, the power module can be a replaceable battery, a rechargeable battery, a solar battery, or the like, as a power source for the smart sensing device 10.

Referring to FIG. 1 and FIG. 2 together, the sensing module 110 of the smart sensing device 10 is used to sense the distance between the user and an external object. As shown in FIG. 2, the sensing module 110 has an ultrasonic sensor 1102 and an infrared sensor 1104. However, the disclosure is not limited thereto. In practical applications, the sensing module 110 can be designed with other sensing devices. The ultrasonic sensor 1102 of the sensing module 110 is composed of an ultrasonic transmitter, an ultrasonic receiver, and a control circuit. The ultrasonic sensor 1102 emits a high-frequency sound wave by the ultrasonic transmitter, and the reflected wave after the object hit by the sound wave is received by the ultrasonic receiver of the ultrasonic sensor 1102. Then, the time when the sound wave is transmitted to the receiving is measured through the control circuit, and the relative distance between the user and the object is calculated according to a formula preset inside the ultrasonic sensor 1102. In addition, the relative speed between the user and the object can be further calculated by the change in the relative distance between the user and the object. It should be understood that the above method is only one embodiment of the present disclosure and is not intended to limit the disclosure.

On the other hand, the infrared sensor 1104 of the sensing module 110 can be used to sense the relative distance between the user and the object and the relative speed. The operating principle is similar to that of the ultrasonic sensor 1102 described above, and will be omitted here. Narration. On the other hand, the infrared sensor 1104 can be further used to sense thermal energy, particularly radiation emitted by body temperature. Therefore, the purpose of the sensor module 110 having both the ultrasonic sensor 1102 and the infrared sensor 1104 is that, in addition to the double sensing, the relative distance between the user and the object and the relative speed are more accurate, and The infrared sensor 1104 can further determine whether the object or the human body is in close proximity to the user.

Referring back to FIG. 1, the positioning module 120 of the smart sensing device 10 is used to record the moving speed of the user. In some embodiments, the positioning module 120 detects the user's moving speed by detecting the user's positioning signal and changing the distance according to the distance within a certain time. Therefore, the sensing module 110 is used to sense the relative distance or relative speed between the user and the object (object or human body), and the positioning module 120 is used to sense the user's own moving speed.

In some embodiments, a global positioning system (GPS) is disposed in the positioning module 120, and the positioning signal of the user and the moving speed of the user can be directly measured in the smart sensing device 10. In some other embodiments, the positioning signal of the positioning module 120 may be from other external satellite positioning devices, such as a satellite positioning system in a mobile phone or other device configured with a satellite positioning system. If the positioning signal of the positioning module 120 is from another device, the positioning module 120 further has a wireless communication system, thereby transmitting signals and data with other external devices. For example, the wireless communication system can be Bluetooth, infrared, wifi, near field communication (NFC), and the like.

The memory 130 of the smart sensing device 10 is a different setting for storing the smart sensing device 10. For example, the memory 130 can be used to store the relative speed or relative distance between the user and the external person or object measured by the sensing module 110, the user's own speed calculated by the positioning module 120, and the like. In this embodiment, the memory 130 is further used to store a judging method and the like of the smart sensing device 10 to be discussed later.

The processor 140 of the smart sensing device 10 is used to integrate the signals and data of the smart sensing device 10 and perform operations. For example, the processor 140 has a signal conversion engine that converts signals stored by other modules (such as the sensing module 110, the positioning module 120, or the memory 130) into an operational form. In addition, the processor 140 can be used to calculate a determination method of the smart sensing device 10 to be discussed later, and the like.

The prompt module 150 of the smart sensing device 10 is for informing the user of the state in which it is located. In some embodiments, for example, when the positioning module 120 records that the user's own speed is higher than a predetermined threshold, the prompting module 150 can notify the user that the user is in a dangerous state, thereby driving the user to slow down the movement. Speed or alertness and so on.

Referring to FIGS. 1 and 3 together, the presentation module 150 has a vibration unit 1502, a display unit 1504, and a sound effect unit 1506. The vibration unit 1502, for example, may be a vibration motor. The display unit 1504 can be a liquid crystal screen, a touch liquid crystal screen, or other kinds of display devices. The sound unit 1506 can be a speaker or the like. Therefore, the smart sensing device 10 can alert the user in a different form by installing different units (such as the vibration unit 1502, the display unit 1504, and the sound effect unit 1506 described above).

In addition, the display unit 1504 further provides an operation interface. In addition to the warning message displayed by the display unit 1504, the user can also perform various functions on the smart sensing device 10 through the display unit 1504 (for example, a touch screen). In some embodiments, for example, the vibration unit 1502, the display unit 1504, and the sound effect unit 1506 do not need to operate simultaneously to present a prompt message to the user, and the user can turn off the vibration unit 1502 and the display unit 1504 in the setting menu. The prompt message, and only the sound emitted by the sound unit 1506 is used to prompt the message. In other embodiments, the prompt message of the sound effect unit 1506 may be turned off, and the prompt message of other units may be turned on. Various settings can be stored in the memory 130 of the smart sensing device 10. Of course, the above embodiments are only one aspect of the disclosure, and are not intended to limit the disclosure.

FIG. 4 is a flow chart of a method of using the smart sensing device according to some embodiments of the present disclosure. Method 20 begins in step S1 and step S2. In step S1, the relative speed or relative distance between the user and the external person or object is recorded by the sensing module. As mentioned above, the sensor module can have an ultrasonic sensor and an infrared sensor, and the time difference between the emitted wave (ultrasonic or infrared) and the reflected wave is used to sense the user and the surrounding person or object. Relative distance and relative speed. In addition, the thermal sensing through the infrared sensor can be used to determine whether the object around the user is a human body.

In step S2, the positioning module records the user's own speed. As mentioned above, the user's own speed is determined by calculating the change in the position of the user's satellite positioning within a fixed time. In addition, the user's satellite positioning information can be obtained through the satellite positioning system in the positioning module. The satellite positioning information of the user can also be obtained by other devices (such as mobile phones or other satellite positioning devices) through the wireless communication system.

In step S3, the data recorded by the sensing module and the positioning module is read into the memory. In detail, step S3 reads the relative speed or relative distance of the user and the external person or object measured in steps S1 and S2, and the user's own speed into the memory.

In step S4, the processor reads the data in the memory. The data read by the processor herein may include the relative speed or relative distance between the user and the external person or object recorded by steps S1 and S2, and the user's own speed. In addition, the processor further includes a judging method for presetting the user into the memory (which will be discussed in detail later), thereby performing corresponding operations in the subsequent steps.

In step S5, it is determined whether the user is in a dangerous state by the data read by the processor. In some embodiments, for example, when the user sets his own speed to exceed a certain threshold, it is determined to be in a dangerous state. When the current speed of the user read by the processor from the memory is greater than the critical value, it is determined to be a dangerous state.

If it is determined in step S5 that the user is in a dangerous state, the process proceeds to step S6, and a warning is issued. As mentioned above, the alert can be prompted by the vibration unit, the display unit, or the sound effect unit in the prompt module in the smart sensing device. In some embodiments, for example, the user can be informed of a dangerous state by simultaneously vibrating, displaying a warning sign on the liquid crystal screen, and making an audible sound. This drives the user to be alert to avoid danger.

If it is determined in step S5 that the user is not in a dangerous state, step S3 is repeated, and the data recorded by the sensing module and the positioning module is continuously read to the memory to continue the subsequent determination.

FIG. 5A is a schematic diagram of an intelligent sensing device according to some embodiments of the present disclosure. In the present embodiment, the smart sensing device 10 has a housing 12, and the housing 12 is a rectangular parallelepiped having six surfaces. The smart sensing device 10 is detachably disposed on a head mounted device 14, such as a locomotive helmet or a bicycle helmet. In some embodiments, the smart sensing device 10 can be configured on other devices, such as directly on the bicycle rear seat, on the user's school bag, or at any possible location.

Further, a display unit 1504 is disposed on one surface of the smart sensing device 10. In the embodiment, the display unit 1504 is a touch screen, and the user can set the interface to configure various settings in the smart sensing device 10. In addition, in the embodiment, since the smart sensing device 10 is disposed on the head mounted device 14, the sensing module 110 is disposed on the four surfaces of the smart sensing device 10, so when the user is traveling (eg, By riding the locomotive, the intelligent sensing device 10 provides the sensing effect of four orientations, which can increase the safety of the user.

In some other embodiments, each surface of the smart sensing device 10 (six surfaces in this embodiment) is configured with a sensing module 110, thereby providing an omnidirectional sensing effect. An advantage of this configuration is that the smart sensing device 10 is detachably disposed directly above the head mounted device 14. If the user places the smart sensing device 10 in another place, such as a bicycle seat cushion, or directly behind the head mounted device 14, since each surface of the smart sensing device 10 is configured with the sensing module 110, the smart The sensed orientation of the sensing device 10 will not be affected by the fact that a surface is not provided with the sensing module 110.

FIG. 5B is a diagram of a method for determining an intelligent sensing device according to some embodiments of the present disclosure. In the present embodiment, the determination method of FIG. 5B is assuming that the user wears the smart sensing device 10 and the head mounted device 14 shown in FIG. 5A and rides on the locomotive to ensure that the user is in the user. Driving safely on the road.

The determination method of FIG. 5B is that the user presets the memory stored in the intelligent sensing device, and the processor reads the data in the memory to perform the determination process. First, the user presets a plurality of threshold values in the smart sensing device and stores them in the memory. The critical values here include the critical value Z of its own speed, the critical value X of the relative velocity of the person or object, and the critical value Y of the relative distance to the person or object. In some embodiments, if the user is riding a locomotive, the speed of 90 km/h (km/hr) may be set as a critical value, and the relative speed of the person or object exceeds 60 km/h (km/hr) as a critical value. Value, and the relative distance to human or object is less than 30 meters (m) is the critical value. In other embodiments, if the user is a pedestrian or a bicycle, the speed of 30 km/h (km/hr) is set as a critical value, and the relative speed of the person or object exceeds 60 km/h (km/hr). ) is a critical value, and the relative distance to human or object is less than 20 meters (m) as a critical value. The above threshold values are merely examples and are not intended to limit the disclosure.

As mentioned above, the user's own speed is measured by the positioning module of the smart sensing device, and the relative speed and relative distance to the person or object are measured by the sensing module.

The determination method of FIG. 5B first determines whether the user's own speed exceeds the critical value Z. If the speed is greater than the critical value Z, it is determined to be in a dangerous state, and the intelligent sensing device sends a warning signal, and the warning signal can be vibration, screen display, or sound effect.

If the user's own speed is less than the critical value Z, it means that the user is at a safe driving speed. The processor then continues to determine if the relative distance to the surrounding person or object is greater than the threshold Y. If the relative distance between the user and the surrounding person or object is greater than the threshold Y, the user is at a safe distance from the person or object around him.

In conclusion, if the processor determines that the relative distance between the user and the surrounding person or object is less than the threshold Y, the user is at an unsafe distance from the surrounding person or object. Therefore, the processor continues to determine whether the relative speed of the user and the surrounding person or object is less than the threshold X. If the relative speed of the user and the surrounding person or object is less than the critical value X, it is determined to be a safe state. However, if the relative speed of the user and the surrounding person or object is greater than the critical value X, it means that the user and the surrounding person or object are not only at an unsafe distance, but also approached at a high speed.

Then, the processor further determines that the human body or the object is close to the user, and the step is to identify through the infrared sensor in the sensing module. If the approaching person is a human body, it is judged to be in a safe state. Conversely, if the approacher is an object (such as a large car, etc.), the processor determines that the state is a dangerous state, and the smart sensing device further issues a warning signal to prompt the user to be alert.

In other embodiments, the processor may predetermine that the human body or object is in proximity to the user, and the user and the human body may have different threshold values (such as relative distance, relative speed, or Self speed). For example, since the moving speed of the human body is relatively slow, the critical value of the relative distance between the user and the human body can be set to 10 meters. Since the object (such as a car) moves faster, the threshold value of the relative distance between the user and the object can be set to 30 meters.

FIG. 6A is a schematic diagram of an intelligent sensing device according to some embodiments of the present disclosure. In the present embodiment, the smart sensing device 10 has a housing 12, and the housing 12 is a rectangular parallelepiped having six surfaces. The smart sensing device 10 is detachably disposed on a strap 16 for the user to wear on the hand.

Further, a display unit 1504 is disposed on one surface of the smart sensing device 10. On the other hand, only the sensing device 10 is provided with a plurality of buttons 18. In the embodiment, the display unit 1504 is a liquid crystal screen, and the user can configure various settings in the smart sensing device 10 through the button 18 and the display unit 1504. In addition, the sensing module 110 is disposed on the plurality of surfaces of the smart sensing device 10, so that when the user is walking, the smart sensing device 10 provides the sensing effect of multiple orientations, which can increase the safety of the user.

FIG. 6B is a diagram of a method for determining an intelligent sensing device according to some embodiments of the present disclosure. In the present embodiment, the determination method of FIG. 6B is assuming that the user wears the smart sensing device 10 and the strap 16 shown in FIG. 6A. For example, the user wears the smart sensing device 10 at night, and the determination method of FIG. 6B is for determining whether there is a human body approaching behind the user.

The determination method of FIG. 6B is that the user presets the memory stored in the intelligent sensing device, and the processor reads the data in the memory to perform the determination process. First, the user presets a threshold value Y of the relative distance between the user and an outside person or object in the intelligent sensing device. For example, the threshold Y of the relative distance may be 20 meters (m), but the disclosure is not limited thereto.

The method of FIG. 6B first determines whether the relative distance between the user and an outside person or object is greater than a critical value Y. As mentioned above, the relative distance between the user and the person or object is measured by the sensing module in the smart sensing device. If the relative distance is greater than the threshold Y, it means that the user is currently in a safe state.

If the relative distance between the user and the external person or object is less than the critical value, it is determined that the relative distance to the user is less than the threshold value Y is a person or thing. As mentioned above, since the sensing module of the smart sensing device is provided with an infrared sensor, the proximity to the user is further recognized by the heat sensing. If it is judged to be an object, it means that the user is in a safe state. If it is judged to be a human body, the prompting module issues a warning to inform the user to alert the suspicious person around him. For example, the reminder module can send a warning signal through the display unit (as shown in FIG. 6A), or can sound through the sound unit to intimidate the surrounding suspicious characters.

It should be understood that the various methods and embodiments described above are merely illustrative of various embodiments of the present disclosure and are not intended to limit the disclosure. In practical applications, the user can design the appearance and configuration position of the intelligent sensing device. You can also design your own way to judge the dangerous state.

The sensing module of the smart sensing device includes an ultrasonic sensor and an infrared sensor, in addition to sensing the relative speed and relative distance between the user and the external person or object. It can also distinguish between the human body and the object, thereby achieving the purpose of multiple sensing.
