Embodiment 1
[0064] Such as figure 1 As shown, this embodiment provides a related measurement and control terminal for temperature and humidity monitoring, including a microprocessor module, a temperature and humidity sensor connected to the microprocessor module using a corresponding data interface, a power management module for supplying power to the measurement and control terminal, and a The NBIoT communication module electrically connected to the microprocessor, and the measurement and control terminal also includes: a dial switch, a hard reset button module and an indicator light; the dial switch, the hard reset button and the indicator light are all electrically connected to the microprocessor module; the hard reset button module , for mandatory initialization of the measurement and control terminal.
[0065] The NBIoT communication module of the measurement and control terminal adopts the standard IoT terminal device management protocol LWM2M to realize remote uplink and downlink c...
Embodiment 2
[0078] Such as figure 2 , image 3 with Figure 4 As shown, this embodiment provides a communication docking method. The measurement and control terminal based on NBIoT communication in Embodiment 1 uses this method to communicate with the cloud platform; the docking process includes the following steps:
[0079] S1. The user inserts the NB IoT card into the measurement and control terminal, sets the switch state of the dial switch in the measurement and control terminal according to the selected cloud platform for uploading data, and starts the measurement and control terminal;
[0080] S2. After the device is started, the measurement and control terminal performs an initialization reset, and configures the connection status of the peripherals connected to the data acquisition module (i.e. the temperature and humidity sensor in Embodiment 1);
[0081] S3. After the configuration of the peripheral connection status is completed, start the NBIoT communication module and perf...
Embodiment 3
[0106] In this embodiment, when the measurement and control terminal has completed the communication connection with the cloud platform, if it is necessary to switch the cloud platform, the following operation mode is adopted:
[0107] S001. Press the hard reset button module to perform a forced initialization operation on the measurement and control terminal;
[0108] S002, shutting down the measurement and control terminal;
[0109] S003. Use the communication docking method in Embodiment 2 to re-connect to the new cloud platform.

Abstract
The invention relates to the field of wireless measurement and control equipment, in particular to a measurement and control terminal based on NBIoT communication and communication docking and switching methods thereof. The measurement and control terminal is a general measurement and control terminal, including a microprocessor module, a data acquisition module electrically connected to the microprocessor module, a power management module, and an NBIoT communication module. The measurement and control terminal also includes: a dial switch, a hard reset button module and light. The dial switch, the hard reset button and the indicator light are all electrically connected with the microprocessor module. The DIP switch is used to control the cloud platform for uploading data selected by the measurement and control terminal. Each switch status bit of the DIP switch establishes a one-to-one correspondence with the type of supported cloud platform; the hard reset button module is used to force the measurement and control terminal to Initialization operation; this docking method mainly enables the user to controllably use the dial switch to limit the selection of the cloud platform for the NBIoT communication module. It overcomes the disadvantage that existing equipment cannot autonomously connect and switch between multiple cloud platforms.
Description
technical field [0001] The invention relates to the field of wireless measurement and control equipment, in particular to a measurement and control terminal based on NBIoT communication and communication docking and switching methods thereof. Background technique [0002] The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., allowing all ordinary physical objects that can be independently addressed to form a new model of interconnected networks. With the continuous advancement of various devices and technologies such as information sensors, radio frequency identification technology, global positioning systems, infrared sensors, and laser scanners, the application of the Internet of Things is becoming more and more extensive. NBIoT (Narrow Band Internet of Things, Narrow Band Internet of Things, Networking) as a cellular network connection technology specially designed for the Internet of Everything has emerged a...
