Abstract

An Internet of things (IoT) system includes a user device for receiving a user setting mode execution command, a sensor for acquiring surrounding environment information based on the user setting mode upon receiving the user setting mode execution command from the user device, and a server device for determining a composite hazard index of environmental conditions based on the acquired environment information and prestored hazard index data and determining that the environmental conditions are hazardous if the composite hazard index is less than a predetermined reference value.

Claims

1. An Internet of things (IoT) system for a vehicle, comprising:

a user device for receiving a user setting mode execution command to control operations of one or more electronic devices of the vehicle;

a sensor for acquiring environment information surrounding the vehicle based on a user setting mode upon receiving the user setting mode execution command from the user device; and

a server device for determining a composite hazard index of environmental conditions based on the environment information surrounding the vehicle and prestored hazard index data, for determining that the environmental conditions are hazardous if the composite hazard index is less than a reference value, and for providing a user of the user device with an alarm message via the user device upon determination that the environmental conditions are hazardous;

wherein the server device receives user satisfaction information about an execution result of the user setting mode and environment information acquired while executing the user setting mode from a plurality of user devices comprising the user device, and reinforces the prestored hazard index data based on the user satisfaction information about the execution result of the user setting mode and the environment information acquired while executing the user setting mode.

2. The IoT system according to claim 1, wherein the prestored hazard index data comprises individual hazard indices for respective types of the environment information and for respective conditions of each type of the environment information in the user setting mode.

3. The IoT system according to claim 1, wherein the server device determines individual hazard indices for respective types of the environment information based on the prestored hazard index data and determines the composite hazard index of the environmental conditions based on the individual hazard indices.

4. The IoT system according to claim 3, wherein if at least one of the individual hazard indices is less than the reference value, the server device determines that the environmental conditions are hazardous by considering the individual hazard indices prior to the determined composite hazard index.

5. The IoT system according to claim 1, wherein the server device determines the composite hazard index based on the user satisfaction information and the environment information, and determines individual hazard indices for respective types of the environment information and for respective conditions of each type of the environment information in the user setting mode based on the environment information and the composite hazard index.

6. The IoT system according to claim 1, wherein the server device transmits the prestored hazard index data to the user device upon request from the user device.

7. The IoT system according to claim 1, wherein the sensor acquires the environment information around the sensor related to the user setting mode among a plurality of sensors.

8. The IoT system according to claim 1, wherein upon receiving a new user setting mode execution command from a user, the server device determines whether the new user setting mode is hazardous based on the prestored hazard index data.

9. A method of controlling an Internet of things (IoT) system of a vehicle, the method comprising steps of:

receiving a user setting mode execution command inputted on a user device to control operations of one or more electronic devices of the vehicle;

acquiring environment information surrounding the vehicle by a sensor based on a user setting mode upon receiving the user setting mode execution command from the user device;

receiving, by a server device, the environment information and determining a composite hazard index of environmental conditions based on the environment information surrounding the vehicle and hazard index data prestored in the server device;

determining, by the server device, that the environmental conditions are hazardous if the composite hazard index is less than a reference value;

providing, by the server device, a user of the user device with an alarm message via the user device upon determining that the environmental conditions are hazardous,

receiving, by the server device, user satisfaction information about an execution result of the user setting mode and the environment information acquired while executing the user setting mode from a plurality of user devices comprising the user device, and

reinforcing, by the server device, the hazard index data based on user satisfaction information about the execution result of the user setting mode and the environment information acquired while executing the user setting mode.

10. The method, according to claim 9, wherein the hazard index data comprises individual hazard indices for respective types of the environment information and for respective conditions of each type of the environment information in the user setting mode.

11. The method according to claim 9, wherein the step of receiving the environment information and determining the composite hazard index of the environmental conditions comprises:

determining individual hazard indices for respective types of the environment information based on the hazard index data, and

determining the composite hazard index of the environmental conditions based on the individual hazard indices.

12. The method according to claim 11, wherein the step of receiving the environment information and determining the composite hazard index of the environmental conditions further comprises:

if at least one of the individual hazard indices is less than the reference value, determining that the environmental conditions are hazardous by considering the individual hazard indices prior to the determined composite hazard index.

13. The method according to claim 9, wherein the step of reinforcing the hazard index data based on the user satisfaction information and the environment information comprises:

determining the composite hazard index based on the user satisfaction information and the environment information, and

determining individual hazard indices for respective types of the environment information and for respective conditions of each type of the environment information based on the environment information and the composite hazard index.

14. The method according to claim 9, further comprising a step of transmitting the hazard index data to the user device by the server device upon request from the user device.

15. The method according to claim 9, further comprising a step of upon receiving a new user setting mode execution command from the user, determining whether the new user setting mode is hazardous based on the hazard index data by the server device.
