Embodiment Construction

[0021] refer to figure 1 , figure 2 with image 3 , a kind of DTU data acquisition method for Internet of Things of the present invention, it is based on the master station and the slave station that can transmit data mutually, comprises the following steps:

[0022] A) Start the system: start the system, judge whether it is necessary to update the online program, and update the program if it needs to be updated;

[0023] B) hardware device initialization: after the system starts successfully, the hardware device is initialized;

[0024] C) Judging the operating mode: after the hardware device is initialized successfully, the running parameters are read. After the parameters are read successfully, the operating mode is judged. The operating mode is one of master mode, slave mode and pass-through mode. Connect the platform, wherein the master station mode will read the stored acquisition address before connecting to the connection platform; D) master station data collection...

Abstract

The invention discloses a DTU data collection method for Internet of things. On the basis of a master station and a slave station which can transmit data to each other, the method comprises the following steps of A, system starting; B, initialization of hardware equipment; C, judgement of a running mode; D, data collection of the master station; E, data sending of the master station; F, data collection of the slave station; G, data sending of the slave station; H, data collection and sending of a pass-through station. According to the DTU data collection method for the Internet of things, in a master-station mode, a modbus command issued by a platform can be received, an address value of the slave station is actively collected and uploaded to the platform, the collected address is remotely updated, runtime parameters are remotely updated, locating of a base station is supported, and DTU firmware is remotely updated; in a slave-station mode, the modbus command issued by the platform can be received, a specified address value of the slave station is periodically uploaded to the platform, the runtime parameters are remotely updated, locating of the base station is supported, and the DTU firmware is remotely updated; in a pass-through mode, the modbus command issued by the platform can be received, a modbus frame initiated by the master station is uploaded to the platform, the runtime parameters are remotely updated, locating of the base station is supported, and the DTU firmware is remotely updated.

Description

【Technical field】 [0001] The invention relates to the technical field of the Internet of Things, in particular to the technical field of DTU data collection. 【Background technique】 [0002] Networking is an emerging concept. To realize the Internet of Things, a large amount of data is required to support it, which inevitably requires receiving, sending and processing various data. The existing data collection method is cumbersome, which is not conducive to the timely collection and processing of data. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a DTU data acquisition method for the Internet of Things, which can make data acquisition more convenient. [0004] In order to achieve the above object, the present invention proposes a DTU data acquisition method for the Internet of Things, which is based on a master station and a slave station that can transmit data mutually, comprising the following...
