The communication diagnosing model determines whether device data of each peripheral device is received. The device communication-status identification model identifies the communication-line of the peripheral device to be normal when the device data is received and determines whether a connection status of the peripheral device is a first category or a second category based on a target data. The communication-line identification model identifies the peripheral device to be offline when the device data is not received and inspects the communication-line of the peripheral device to determine whether the connection status of the peripheral device is the second category or a third category. The graphic updating model updates a displaying icon of each peripheral device based on the connection status of each peripheral device. ## Claims ### Claim 1 A self-diagnosing system for connection status of devices, the self-diagnosing system connected with multiple peripheral devices for communication in an environment, comprising: a graphic control page;
