The method may be applied to an industrial device accessing a communication network through a CPE (Customer Premise Equipment, customer premises equipment). As shown in fig. 1, the method may include, but is not limited to, the steps of:
step S101: and sending a first message to the network side equipment at intervals of a first preset time.
For example, the industrial device sends a first message to the network device every first preset time (e.g., 30 seconds). The first message is used for enabling the network side equipment to return a response message.
In this embodiment of the present application, the first message may be an ICMP (Internet Control Message Protocol ) echo request packet.
Step S102: and responding to the second message received from the network side equipment and fed back in the second preset time, and sending the access information to the network side equipment.
For example, the industrial device sends current access information of the industrial device to the network side device in response to receiving the second message fed back by the network side device within the second preset time.
In this embodiment of the present application, the second message may be an ICMP echo reply packet.
In one implementation, the access information includes at least one of: cell ID (Identity document, identity) of the serving cell in which the industrial equipment is located; RSRP (Reference Signal Receiving Power, reference signal received power); RSRQ (Reference Signal Receiving Quality, reference signal received quality); SINR (Signal to Interference plus Noise Ratio ).
Step S103: and receiving configuration information sent by the network side equipment.
In the embodiment of the present application, the configuration information is configured by the network side device based on the access information.
For example, the industrial device receives configuration information sent by the network side device. The configuration information is obtained by judging whether the current access state of the industrial equipment is normal or not based on the access information after the network side equipment receives the access information sent by the industrial equipment, and reconfiguring the access configuration parameters of the industrial equipment after determining that the current access state of the industrial equipment is abnormal.
Step S104: the communication network is re-accessed based on the configuration information.
For example, the industrial device adjusts the wireless access parameters based on the configuration information sent by the network side device to re-access the communication network.
In other embodiments of the present application, if the industrial device receives the configuration information sent by the network side device, the industrial device does not process the configuration information, and continues to maintain the current network connection.
By implementing the embodiment of the application, the industrial equipment can send the first message to the network side equipment, and after receiving the second message fed back by the network side equipment, send the access information to the network side equipment, so that the network side equipment configures relevant access parameters of the industrial equipment. The industrial equipment can receive the configuration information sent by the network side equipment and re-access the communication network based on the configuration information. The industrial equipment can be ensured to be normally connected to the communication network, so that the reliability of data transmission of the industrial equipment is ensured, and the normal operation of the industrial equipment is further ensured.
In one implementation manner, if the second message fed back by the network side device is not received within the second preset time, the first message may be sent to the network side device again, so as to determine whether the network link is normal. As an example, please refer to fig. 2, fig. 2 is a flow chart of another method for accessing industrial equipment according to an embodiment of the present application. The method can be applied to industrial equipment. As shown in fig. 2, the method may include, but is not limited to, the steps of:
step S201: and sending a first message to the network side equipment at intervals of a first preset time.

Step S202: and responding to the second message which is not fed back by the network side equipment at the second preset time, and continuously sending the first message to the network side equipment for N times.
In the embodiment of the present application, N is a positive integer.
For example, the industrial device continuously sends the first message to the network side device three times in response to not receiving the second message fed back by the network side device within the second preset time.
Step S203: and responding to the second message received by the network side equipment and fed back in the third preset time, and sending access information to the network side equipment.
For example, the industrial device sends the current access information to the network side device in response to receiving the second message fed back by the network side device within a third preset time (e.g., 40 seconds) after continuously sending the first message N times to the network side device.
In the embodiment of the present application, the first preset time, the second preset time, and the third preset time may be the same or different.
Step S204: and receiving configuration information sent by the network side equipment.

Step S205: the communication network is re-accessed based on the configuration information.
In the embodiment of the present application, step S205 may be implemented in any manner in each embodiment of the present application, which is not limited to this embodiment, and is not described in detail.
By implementing the embodiment of the application, the industrial equipment can send the first message to the network side equipment, and can send the first message to the network side equipment again when the second message fed back by the network side equipment is not received within the second preset time, so as to determine whether the network link is normal. The industrial equipment can be ensured to be normally connected to the communication network, so that the reliability of data transmission of the industrial equipment is ensured, and the normal operation of the industrial equipment is further ensured.
In other embodiments of the present application, the communication network is re-accessed in response to not receiving the second message fed back by the network side device within a third preset time.
For example, the industrial device re-accesses the communication network in response to not receiving the second message fed back by the network side device within a third preset time after continuously sending the first message to the network side device N times. For example, the industrial device redials or restarts the network access device.
Referring to fig. 3, fig. 3 is a flow chart of another access method of industrial equipment according to an embodiment of the present application. The method is applied to the network side equipment. As shown in fig. 3, the method may include, but is not limited to, the steps of:
step S301: in response to receiving the first message sent by the industrial device, a second message is sent to the industrial device.
For example, the network-side device sends a second message to the industrial device in response to receiving the first message sent by the industrial device.
Step S302: and receiving the access information sent by the industrial equipment.
For example, the network side device receives access information sent by the industrial device, where the access information is access information of the industrial device to the communication network.
Step S303: configuration information is obtained based on the access information.
For example, the network side device judges whether the current access state of the industrial device is normal based on the access information, and reconfigures the access configuration parameters of the industrial device to obtain configuration information after determining that the current access state of the industrial device is abnormal.
In other embodiments of the present application, if the network side device determines that the current access state of the industrial device is normal based on the access information, the access configuration parameters of the industrial device may not be reconfigured.
Step S304: the configuration information is sent to the industrial device.
Wherein the configuration information is used for the industrial device to re-access the communication network.
For example, the network-side device sends configuration information to the industrial device to cause the industrial device to adjust network access parameters based on the configuration information to re-access the communication network.
By implementing the embodiment of the application, the network side device can feed back the second message to the industrial device when receiving the first message sent by the industrial device, acquire the configuration information based on the access information of the industrial device, and send the configuration information to the industrial device so that the industrial device can re-access the communication network based on the configuration information. The industrial equipment can be ensured to be normally connected to the communication network, so that the reliability of data transmission of the industrial equipment is ensured, and the normal operation of the industrial equipment is further ensured.
