Embodiment 1

[0033] see figure 2 , which is a flowchart of an embodiment of a data transmission method in a private network communication of the present application, including the following steps:

[0034] Step 201: Obtain the data transmission identifier of the terminal, wherein the data transmission identifier is used to indicate the number of standardized transmission durations for the terminal to transmit data in the current transmission cycle, and the standardized transmission duration is a data transmission duration longer than The preset protection time is added and summed, and the protection time is the maximum value of the time delay generated by the internal transmission and processing of all terminals in the private network communication system;

[0035] According to the customer's needs, the terminal in the private network communication sends data at least once within a certain period of time, and this period of time is a data transmission cycle. Similarly, when receiving dat...

Embodiment 2

[0062] Compared with the above-mentioned first embodiment, the difference of this second embodiment is: before the above-mentioned step 203, it is also necessary to judge whether the terminal is in the data transmission service state, if not in the data transmission service state, switch the terminal to the data transmission service state, To ensure the smooth transmission of data. see Figure 4 , which is a flow chart of another embodiment of a data transmission method in a private network communication of the present application, including the following steps:

[0063] Step 401: Obtain the data transmission identifier of the terminal, wherein the data transmission identifier is used to indicate the number of standardized transmission durations for the terminal to transmit data in the current transmission cycle, and the standardized transmission duration is a transmission duration of data and The preset protection time is added and summed, and the protection time is the maxi...

Embodiment 3

[0075] The following takes the GPS data sending by the terminal A in the GPS system of private network communication as an example to describe its data sending method in detail. see Figure 5 , which is a flow chart of a data sending method in a GPS system for private network communication of the present application, comprising the following steps:

[0076] Step 501: After the terminal A is powered on, it sends a data transmission identification allocation request to the communication center in the system, and the data transmission identification allocation request includes the terminal identification of the terminal A;

[0077] Step 502: The communication center obtains the data transmission identification of terminal A according to the corresponding relationship between the terminal identification and the data transmission identification, and assigns it to terminal A;

[0078]Of course, terminal A can also only send a data transmission identification allocation request to t...

Abstract

The embodiment of the invention discloses a data transmission method and a data transmission device for private network communication. The method comprises the following steps of: acquiring a data transmission identifier of a terminal, wherein the data transmission identifier is used for indicating a standard transmission time length within which data is transmitted in a current transmission period to the terminal, wherein the standard transmission time length is the sum of a data transmission time length and preset guard time; resolving the data transmission identifier to obtain the position of the standard transmission time length within which the data can be transmitted by the terminal in the current transmission period; and when the standard transmission time length within which the data can be transmitted by the terminal is determined to be reached, and the terminal is in a data transmission service state, starting transmitting the data. According to the embodiment of the invention, the problems of low channel resource utilization rate and incapability of ensuring the data transmission period of the terminal in the prior art can be solved.

Description

technical field [0001] The present application relates to the field of private network communication, in particular to a data transmission method and device in private network communication. Background technique [0002] Dedicated communication network or private network, as a supplement to public communication network or public network, refers to the construction within some industries, departments or units to meet their organizational management, safety production, dispatching and commanding, etc. Communications network. Generally, it only provides non-commercial telecommunication services internally, and does not undertake the obligation of universal service to the society. For example, dedicated communication networks have been widely used in fields such as electric power, petroleum, metallurgy and transportation. Today, with the development of society and the advancement of technology, the status and role of private networks are constantly changing. [0003] see fig...
