Description

Charging system for IoT devices using autonomous vehicles

The present invention relates to an IoT device charging system using an autonomous vehicle, and in particular, an autonomous vehicle that allows an autonomous vehicle operating in a village to automatically charge the battery of an Internet of Things (IoT device) used in a specific area. It relates to an IoT device charging system using a driving device.

In general, in a specific area, such as a transportation marginalized area, there is also a shortage of public transportation, and there are places where there is no public transportation at all.

There are cases where public autonomous vehicles are used to provide transportation, etc. in these traffic-neglected areas. In order to use an autonomous vehicle, it is necessary to know the operating time of the village in advance or to call the autonomous vehicle through a call.

In this way, in a village in a traffic-restricted area, a device for calling an autonomous vehicle or notifying the outside of an emergency is provided for each house or a certain place, and this is called an Internet of Things (IoT) device.

The IoT device is implemented with a communication module for communication with the control server, an input module for receiving a call signal, a detection module for detecting an emergency, and a power supply module for supplying power.

The power supply module generally uses a rechargeable battery, and the battery is operated in such a way that the user manually charges or replaces the battery.

Therefore, manpower for replacing or charging the battery and manpower for checking the battery are required, causing a waste of manpower.

When the battery is completely discharged, the IoT device does not operate, and in this case, it becomes impossible to make a call even in an emergency. When an emergency occurs in a situation where the battery of the IoT device is not working because the battery is discharged, precious life may be lost due to the inability to make an external call.

On the other hand, a conventional technique of using an Internet of Things (IoT) device for a traffic marginalized area or the traffic weak is disclosed in <Patent Document 1> below.

In <Patent Document 1>, it is possible to easily check the expected arrival time of the bus, weather information, and traffic information at the bus stop, and it has a power saving function to save energy when the user is not present, and calls taxi or auxiliary service when the bus is finished. You can easily request a support taxi. In addition, information on public transportation and taxi use by bus stop can be analyzed and referenced for operation, and in case of an emergency, a stop information guide system is provided for the vulnerable in transportation that can notify security agencies. In such a stop information guide system, a sensor for user detection is used, and power supply is required to operate these sensors.

A battery for power supply is used for power supply, and the battery maintains the state of the battery by manually charging or replacing the battery, which also causes a waste of manpower for charging the battery.

First, the battery module 111 of the IoT device 110 installed in a specific place (eg, a traffic area) detects the remaining amount of the built-in battery in real time and transmits it to the controller 115 .

The control unit 115 compares the detected remaining battery amount with a preset set value (for example, set to 30% of the battery charge amount) to check whether the battery is charged, and when the remaining battery level is less than the set value, the battery should be charged. It makes a decision and generates battery charge request data. The battery charge request data generated here may include battery state information (battery charge amount), location coordinate data of the IoT device, and identification information (ID) of the IoT device.

After the generated battery charging request data is encrypted through the security unit 113 , it is converted into data of a communication method set through the IoT communication unit 114 and transmitted to the gateway 200 .

It moves and performs a wireless charging operation again.

In this process, when all charging of the charging target IoT device is completed, the autonomous vehicle 400 returns to the set position.

As described above, the present invention automatically wirelessly charges the battery of the IoT device using a non-driving autonomous vehicle, thereby reducing the manpower for manually charging the battery or replacing the battery.

In addition, in the "IoT device charging method using an autonomous vehicle" according to the present invention, (d) when the battery is fully charged while charging the battery in the wireless charging method in the IoT device, battery charging completion information is generated and the gateway is connected to the gateway. Step (S17), (e) of transmitting to the IoT control server through the IoT control server, upon receiving the charging completion information from the IoT device, transmits the charging termination information to the autonomous vehicle, It may further include the step of stopping the battery charging (S18 - S19).

A method of charging an IoT device using an autonomous vehicle according to a preferred embodiment of the present invention configured as described above will be described in detail as follows.

First, in step S11 , the battery module 111 of the IoT device 110 installed in a specific place (eg, a traffic-restricted area) detects the remaining amount of the built-in battery in real time and transmits it to the controller 115 .

The control unit 115 compares the detected remaining battery amount with a preset set value (for example, set to 30% of the battery charge amount) to check whether the battery is charged, and when the remaining battery level is less than the set value, the battery should be charged. It makes a decision and generates battery charge request data.

The battery charge request data generated here may include battery state information (battery charge amount), location coordinate data of the IoT device, and identification information (ID) of the IoT device.

After the generated battery charging request data is encrypted through the security unit 113 , it is converted into data of a communication method set through the IoT communication unit 114 and transmitted to the gateway 200 .

When the gateway 200 receives the battery charging request data from the specific IoT device 110 , it stores it in the storage unit 203 , processes it with a preset encryption algorithm through the security unit 202 , and then sends the data to the thing in the communication unit 201 . Data of a predetermined communication method with the Internet control server 300 is created and transmitted to the IoT control server 300 .

In step S12 , the IoT control server 300 receives battery charging request data from the specific IoT device 110 , stores it in the storage unit 302 , and starts charging scheduling in the charging control unit 304 . Here, charging scheduling refers to finding autonomous vehicles in non-operating time zones among autonomous vehicles operating in a given area.

Self-driving cars during non-operational hours can be easily navigated by referring to the schedule. Through such charging scheduling, when autonomous driving vehicles in non-operating time zones are searched for among autonomous driving vehicles operating in the region, the discovered autonomous driving vehicle is selected as a charging target autonomous vehicle.

Next, the charging reservation information to be transmitted to the corresponding autonomous vehicle is generated and transmitted to the autonomous vehicle 400 through a preset communication method with the autonomous vehicle 400 . Here, the charging reservation information may include charging time information and location coordinate data of the charging target IoT device.

When there are a plurality of charging target IoT devices, it is preferable to schedule and deliver location coordinate data of the plurality of charging target IoT devices and charging time information of the corresponding charging target IoT devices.

In step S13 , the communication unit 401 of the autonomous vehicle 400 receives the charging reservation information and transmits it to the control unit 404 . The control unit 404 stores the transmitted charging reservation information in the storage unit 402 , and transmits response data indicating that the charging reservation information has been received to the IoT control server 300 .

Next, in step S14 , the autonomous vehicle 400 checks whether the charging time has arrived based on the charging time information. As a result of this check, when the charging time arrives, it moves through autonomous driving to the place where the IoT device is installed using the location coordinate data. Thereafter, when moving to the location of the location coordinate data, the wireless power transmitter 403 transmits wireless power for wireless charging. Here, the wireless charging method may use a magnetic induction method, a magnetic resonance (resonance) method, an electromagnetic wave method, or the like, and it is assumed that a magnetic resonance method is used as an embodiment of the present invention. In addition, when charging starts, the control unit 404 transmits charging start data to the IoT control server 300 to notify the charging start.

The IoT device 110 receiving the charging start data in step S16 checks whether wireless power is received through the wireless charging unit 116 .

If the wireless power is not received as a result of this check, it is transmitted to the IoT control server 300 , and the location coordinate data is sent back to change the location of the vehicle so that the location of the autonomous vehicle 400 can be changed.

On the contrary, when wireless power for charging is received, wireless power is received in step S17 to charge the battery built into the battery module 111 .

The battery module 111 continuously detects the remaining amount of the battery, and the controller 115 checks the detected remaining amount of the battery. As a result of this check, when the battery charge reaches 100%, charging completion information is generated and transmitted to the gateway 200 through the IoT communication unit 114 .

The gateway 200 transmits the received charging completion information to the remote IoT control server 300 through the communication unit 201 .

In step S18 , when the IoT control server 300 receives charging completion information of a specific IoT device through the gateway 200 , it generates charging termination information and transmits it to the autonomous vehicle 400 . Here, the charging termination information includes identification information for identifying the IoT device that is the charging termination target.

In step S19, the control unit 404 of the autonomous vehicle 400 receives the charging termination information from the IoT control server 300, identifies the charging termination target IoT device through the identification information, and the wireless power transmission unit 403 to stop wireless charging of the IoT device.

Next, the autonomous vehicle 400 checks the charging reservation information to check whether there are other charging target IoT devices, and if there are other charging target IoT devices, the autonomous vehicle 400 returns to the corresponding location based on the location coordinate data of the corresponding IoT device. It moves and performs a wireless charging operation again.

In this process, when all charging of the charging target IoT device is completed, the autonomous vehicle 400 returns to the set position.
