Problems solved by technology

Usually, the Socket connection method first needs to shake hands to confirm that both parties have been verified and is safe before establishing a connection and interactively transmitting data. However, when the network is disconnected, the handshake and connection establishment must be done again, and the connection must always be maintained. If Intermittently will cause repeated handshakes, establishing connections and maintaining connections, which wastes network costs and is inefficient

Embodiment 1

[0020] A vending machine is an unmanned remote device. The information that needs to be transmitted includes transaction information, warehouse sales information, cumulative sales total information, error information, door opening and closing information, cumulative transaction information, price cumulative sales information, and warehouse sales information. Complete information, etc., under unstable network conditions, the input data is transmitted in the form of data structure cutting, and is transmitted in different packets. The principle of each packet is no more than 2KB. Make the data smaller so that it can still be transmitted under unstable signals. There is a unique value UID in each packet, and the above data is recorded with the UID value, and the UID value is judged to determine whether the data is repeated, and if it is repeated, it will not be transmitted.

[0021] Most of the continuous transmission of data adopts the Socket method, especially in game software t...

Embodiment 2

[0026] Take the vending machine as an example. When using the vending machine for the first time, the vending machine must be registered to obtain the verification of the service product side. At this time, you must first use the account and password initialized by the system to log in. After the verification is successful, the server will send another set of CheckID and CheckPassword to the terminal device. After the registration is successful, the terminal establishes a connection with the server and sends a login request. At this time, enter the login information such as CheckID, CheckPWD, etc., and confirm that you have login authority through verification. If the vending machine has not obtained the SessionKey, the server will A set of SessionKey is generated, and the terminal device is required to carry the SessionKey to verify the identity and data correctness when heartbeating and transmitting data. The server periodically requires the terminal device to change the Sess...

Abstract

The invention relates to an unmanned remote device, and especially to the data transmission of an unmanned remote device. The invention provides a data transmission method of the unmanned remote device, which includes the steps of: establishing online with a server and transmitting data. The data is transmitted through a data structure cutting mode. A method for establishing online with the server includes the steps of: registering and obtaining the verification of a server side; firstly using a system default initialized account number and a password to log in the server; after the verification is successful, sending another group of a check ID and a Check Password to a terminal device by the server side; and after the register is successful, establishing online with the server side by a terminal, sending a demand for asking for Login, inputting login information of the Check ID and the Check PWD at this time, and confirming to have a login authority through verification. The data transmission method of the unmanned remote device has the following advantages that the transmission is still performed rightly when network signals are not stable, the repeatable transmission is not performed, and the network cost is saved.

Description

technical field [0001] The invention relates to an unmanned remote device, in particular to data transmission of the unmanned remote device. Background technique [0002] For unmanned remote equipment in unmanned management devices, it is necessary to know the various conditions of the unmanned remote equipment at all times, and send the message back to the server through the 3G and 4G wireless network, but the unstable 3G or 4G network signal is often disconnected, resulting in data damage Incomplete or completely unable to transmit, resulting in the remote device being unable to know the current status of the device and network communication in real time. Moreover, there is also a security problem in wireless network transmission, which can be stolen or changed during the transmission process. [0003] Most of the continuous transmission of data adopts the Socket method, especially in game software transmission data, but games are usually used on computers with a good net...
