Embodiment 1

[0107] A thermostat that supports the 485 bus contains 6 temperature control inputs, and its data communication application protocol is shown in Table 1 below:

[0108] Table 1 Application protocol of data communication of thermostat

[0109]

[0110] Among them, the address range of the 6-way temperature control input is shown in Table 2:

[0111] Table 2 The address range of the 6-way temperature control input of the thermostat

[0112]

[0113]

[0114] According to this, the returned data format of the thermostat read temperature function is shown in Table 3:

[0115] Table 3 Return data format of temperature controller read temperature function

[0116]

[0117] Assuming that the gateway is required to monitor the device, the configuration information of the monitoring task is as follows:

[0118] 1. Device access bus and communication parameters

[0119] The bus type is 485 bus, and the gateway supports it through the serial port to 485. The communication...

Abstract

The invention relates to a protocol self-adaptation method based on a monitoring cloud platform and a gateway. The method comprises the steps as follows: the gateway and the monitoring cloud platformbuild a connection, and are connected with terminal equipment; the monitoring cloud platform builds a monitoring task according to configuration information input by a user, and sends the monitoring task to the gateway; the gateway receives and runs the monitoring task, initializes a bus controller corresponding to an equipment access bus via a communication parameter, and execution command data accesses the terminal equipment; a return data packet acquired by the execution command data is packaged and reported to the monitoring cloud platform after being verified via a return data packet verification rule; and the monitoring cloud cuts out corresponding data content from the return data packet according to an analysis rule of the return data packet preset by the user. According to the method and system provided by the invention, the protocol self-adaptation method based on the monitoring cloud platform and the gateway can conveniently and flexibly access the different equipment of thedifferent buses without customized development, and thus non-developers can complete self-adaptation configuration.

Description

technical field [0001] The invention relates to the technical field of gateway systems, in particular to a protocol adaptive method and system based on a monitoring cloud platform and a gateway. Background technique [0002] In the era of the Internet of Things, various terminal devices for industrial monitoring are highly specialized, so that the access buses used by various terminal devices to access the gateway and monitoring system may be different. may be different, so existing gateways and monitoring systems need to be customized for the bus and upper-layer application communication protocols. In order for the gateway to support heterogeneous network modules, two kinds of gateway self-adaptation technologies have been developed: ① A variety of adaptation protocols are pre-stored on the gateway firmware, and when the device is connected, a combination of the characteristics of the received data packet and the pre-stored adaptation protocol list is performed. ② Matching...
