In this process, the central control device will send some login messages to be parsed to verify the user's identity and authorize it to use the shared electric bicycle. These login messages to be parsed typically contain the user's mobile phone number or other identity identifier, information about the central equipment provider of the shared electric bicycle, other authentication information, and the like.
The communication protocol formats used by the central control devices produced by different suppliers are different, so that a plurality of device gateways developed in different communication protocol formats exist at a platform end.

In the invention, a preset communication protocol format is a communication protocol format which can be analyzed by a device gateway (namely, a device gateway A) which currently receives a login message to be analyzed, wherein the login message in the preset communication protocol format is generated by first target central control equipment (marked as central control A), namely, the device gateway A can directly analyze the login message when determining that the login message is sent by the central control A; for the login message sent by the non-central control A, at this time, the device gateway A judges that the login message cannot be resolved, that is, the login message to be resolved does not conform to the communication protocol format preset in the device gateway A, and the target communication protocol format needs to be further determined according to the content of the login message. In the present invention, the communication protocol format used by the central control device corresponding to the message, i.e. the target communication protocol format, can be deduced according to the information contained in the message, such as the device ID, the vendor information, the IP address, the MAC address, etc.
Step 203, based on the mapping relationship between the communication protocol format and the device gateway information, obtaining the communication connection information of the target device gateway corresponding to the login message to be resolved according to the target communication protocol format.
In the invention, the mapping relation between the communication protocol format and the equipment gateway information is established in the early stage. For each communication protocol format, there is corresponding device gateway information, including the IP address and port number of the device gateway, and so on. Further, after the target communication protocol format is determined, the communication connection information of the target device gateway corresponding to the login message can be obtained according to the mapping relation, where the communication connection information includes an IP address and a port number of the target device gateway, and the like, and the communication connection information can be used for establishing a subsequent communication connection between the second target central control device and the target device gateway.

In the invention, the login message to be analyzed can be analyzed and judged through a pre-constructed script (such as lua script), so that the communication connection information of the target equipment gateway corresponding to the login message can be obtained. Then, the communication connection information needs to be sent to the second target central control device, after the second target central control device receives the information, communication connection can be established with the target device gateway according to the communication connection information, so that the second target central control device can establish a long connection session with the target device gateway according to the information and is used for receiving and sending data in real time, at the moment, the second target central control device sends the login message to be analyzed to the target device gateway again, so that the login message to be analyzed can be analyzed by the target device gateway, and the analysis result is pushed to the cloud platform.
According to the communication connection method of the central control equipment, when the acquired login message to be analyzed is not the message sent by the first target central control equipment, the communication connection information of the target equipment gateway corresponding to the login message to be analyzed is acquired according to the target communication protocol format based on the mapping relation between the communication protocol format and the equipment gateway information, and further the communication connection information is sent to the second target central control equipment according to the long connection object information of the central control equipment corresponding to the login message to be analyzed, so that the communication connection between the second target central control equipment and the target equipment gateway is established, and the communication efficiency between the central control equipment and the equipment gateway is improved.

In the invention, the central control B sends a TCP long connection request to the equipment gateway based on the IP address information and the port information exposed by the equipment gateway. If the TCP long connection request is not received by the device gateway B corresponding to the central control B, but is received by the device gateway A, at the moment, the TCP long connection between the second target central control device and the device gateway A is established. After the TCP long connection is established, the device gateway a can receive the message from the second target central control device, including the login message to be resolved, and further analyze the login message to be resolved through a subsequent step, so as to obtain the relevant information of the device gateway that can resolve the login message to be resolved.
On the basis of the above embodiment, after the setting up of the TCP long connection with the second target central control apparatus, the method further includes:

Further, after the communication connection information of the second target central control device is determined, long connection object information corresponding to the second target central control device needs to be obtained from the hash table according to the ID number corresponding to the TCP long connection. This procedure can obtain corresponding long connection object information by looking up an item whose key value is an ID number in the hash table. If the lookup fails, it indicates that the connection is not present or has failed, requiring corresponding processing.
