Abstract
A hub device providing a diagnostic function and a diagnostic method using the same are disclosed. The hub device includes: a communication unit receiving a first type of data from plural service devices to transmit the first type of data to an access point device and receiving a second type of data from the access point device to transmit the second type of data to at least one of the service devices; and a controller controlling the communication unit and performing diagnosis for the service devices and the access point device.
Claims9
A hub device providing a diagnostic function, comprising:
- a communication unit receiving a first type of data from plural service devices to transmit the first type of data to an access point device and receiving a second type of data from the access point device to transmit the second type of data to at least one of the service devices;
- and
- a controller controlling the communication unit and performing diagnosis for the service devices and the access point device in a different time schedule in each diagnostic section;
- wherein the controller performs a first-section diagnosis to check communication state of the service devices and operation state of each of the service devices, and the controller performs second-section diagnosis to check communication state between the hub device and the access point device and operation state of the access point device after performing the first-section diagnosis;
- wherein the service device is a washing machine or drying machine or clothes cleaning machine installed in a store, and the service device receives control information generated by a operation management device from the server;
- the operation management device monitors or controls the plural service devices remotely via the server or the hub device;
- the hub device transmits an emergency message including a diagnosis result to the operation management device when a ratio of a number of service devices in abnormal operation to a total number of installed service devices, among the service devices, exceeds a reference value;
- and
- wherein the controller generates a message instructing a specific service device to stop operation, the specific service device being a service device that is confirmed to have an abnormality in operation state or communication state based on results of the first-section diagnosis, and the communication unit transmits the message to the specific service device.

A method of performing a diagnostic function by a hub device, the hub device comprising:
- a communication unit directly communicating with plural service devices and an access point device;
- and a controller controlling the communication unit, the method comprising:
- performing, by the controller, a first-section diagnosis to check communication state between the hub device and each of the service devices and operation state of each of the service devices;
- performing, by the controller, a second-section diagnosis to check communication state between the hub device and the access point device and operation state of the access point device;
- performing, by the controller, a third-section diagnosis to check connection state of the hub device to an external public server and the Internet via the access point device;
- and
- performing, by the controller, a fourth-section diagnosis to check communication state between the hub device and a server and operation of the server via the access point device;
- wherein the controller performs diagnosis in each diagnostic section with a different time schedule;
- wherein the service device is a washing machine or drying machine or clothes cleaning machine installed in a store, and the service device receives control information generated by a operation management device from the server;
- the operation management device monitors or controls the plural service devices remotely via the server or the hub device;
- the hub device transmits an emergency message including a diagnosis result to the operation management device when a ratio of a number of service devices in abnormal operation to a total number of installed service devices, among the service devices, exceeds a reference value;
- generating, by the controller, a message instructing a specific service device to stop operation, the specific service device being a service device that is confirmed to have an abnormality in communication state or operation state based on results of the first-section diagnosis;
- and
- transmitting, by the communication unit, the message to the specific service device.
