[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...
