Example Embodiment

[0015] Example 1

[0016] Such as figure 1 with figure 2 As shown, an IoT disconnected resumable transmission system includes an IoT terminal and a cloud server that communicates data with the IoT terminal through wireless transmission. Each IoT terminal has a unique ID number, which can be accessed through GPRS, NB -IOT and other wireless transmission methods communicate data with the cloud server, actively initiate a connection, the cloud server identifies each IoT terminal through the ID number, the cloud server has a fixed IP address or domain name, and the cloud server opens a fixed port number, all The IoT terminal establishes a TCP or UDP connection with the cloud server through this port number, and supports the issuance of data analysis, storage, and control commands. The IoT terminal includes a data acquisition module, a CPU module, a control module, and a wireless transmission module. The data acquisition module can collect analog quantity, switching value or pulse si...

[0017] Example 2

[0018] Such as image 3 As shown, an Internet of Things disconnected resumable transmission method in the Internet of Things disconnected resumable transmission system, including the Internet of Things disconnected resumable upload method and the Internet of Things disconnected resumable upload method, the Internet of Things disconnected resumable transmission method The upload method includes the following steps: (1) The Internet of Things disconnected uploading system includes the Internet of Things terminal ID number, signal real-time value and acquisition time. The Internet of Things terminal has a fixed signal acquisition period and records the real-time value of the data when collecting data. And the collection time; after each signal collection cycle, the IoT terminal first judges whether the network between the IoT terminal and the cloud server is normal according to the TCP or UDP Socket connection status. If it is normal, the IoT terminal ID number an...

Abstract

The invention discloses an Internet-of-things disconnection continuous transmission system and an Internet-of-things disconnection continuous transmission method of the Internet-of-things disconnection continuous transmission system. The system comprises an Internet-of-things terminal and a cloud server terminal in data communication with the Internet-of-things terminal in a wireless transmissionmode. The system further comprises an Internet-of-things offline continuous uploading system and an Internet-of-things offline issuing system, the Internet-of-things offline continuous uploading system comprises an Internet-of-things terminal ID number, a signal real-time value and acquisition time, the Internet-of-things terminal has a fixed signal acquisition period, and the data real-time valueand the acquisition time are recorded during data acquisition. The control reliability is enhanced; the control command has a memory function, if the network is unstable when a user issues the control command, the loss of the control command cannot be caused, and once the Internet-of-things terminal and the cloud server network return to normal, the cached control command can be issued, so that the control reliability is enhanced; the influence of network disconnection on an Internet-of-things system is reduced; the Internet-of-things disconnection continuous transmission system aims to reduce the influence of instability or disconnection of a wireless network on an Internet-of-things system, and ensures that Internet-of-things terminal data is not lost and a control command does not fail.

Description

technical field [0001] The invention relates to the monitoring field of the Internet of Things, in particular to an Internet of Things continuous transmission system and a method for the system of the Internet of Things continuous transmission after disconnection. Background technique [0002] At present, the domestic Internet of Things has been more and more popularized and applied in the fields of chemical industry, municipal administration, agriculture, and water conservancy. The Internet of Things is based on GPRS or NB-IOT technology. In the application field, the wireless network is unstable, and the disconnection of the wireless network often occurs, resulting in data loss and control command failure. troubled. [0003] How to ensure the integrity of the data when the wireless network is unstable, and how to ensure that the control commands issued by the user to the IoT terminal are not invalid is a problem that needs to be solved urgently. Contents of the inventio...
