The first preset time length and the second preset time length can be set according to requirements.
The embedded device 20 is specifically configured to receive the operation state information of the local area network device 10 when the local area network device 10 is in the first operation state, and not receive the operation state information of the local area network device 10 when the local area network device 10 is in the second operation state. The first operating state is a normal operating state, i.e. a state without failure, and the second operating state is an abnormal operating state, i.e. a failure state. In one approach, the running state information is sent to the embedded device 20 at intervals when the in-lan device 10 is in the first running state, and the sending of the running state information to the embedded device is suspended when the in-lan device 10 is in the second running state.
In one embodiment, the apparatus operates as follows:
When the local area network equipment 10 does not have a fault, the local area network equipment 10 and the embedded device 20 (local area network single chip microcomputer) perform information intercommunication through the local area network, the local area network equipment 10 sends a heartbeat packet for normal operation of the equipment to the embedded device 20 at intervals (such as 2 s), and the embedded device 20 gathers all received information to generate two-dimensional code information after receiving the heartbeat packet for a period of time;

If the equipment 10 in the local area network fails, the heartbeat packet is not sent to the embedded device 20, the two-dimension code displayed by the embedded device 20 is kept unchanged all the time, the operation and maintenance device 30 does not send the same data to the server 40 when receiving the same two-dimension code, the server 40 judges that the equipment 10 in the local area network is out of connection because of not receiving new data for a long time, and fault information is sent to the mobile client for alarming.
In addition, when the in-lan device 10 does not transmit the heartbeat packet information to the embedded apparatus 20 for a preset period of time (for example, 3 minutes), the alarm 60 considers that the in-lan device 10 has a connection failure (i.e., the in-lan device 10 is abnormal), and the alarm alarms.
The operation and maintenance device 30 typically employs a wide area network to transmit signals, such as a 4G network. I.e., the operation and maintenance device 30 establishes a connection with the server 40 through the wide area network.
In connection with fig. 1, the present application also provides an abnormality detection system 200, including any one of the abnormality detection apparatuses 100 described above and an in-lan apparatus 10 for detecting whether or not the in-lan apparatus has failed.
