Push messages such as announcements, news, advertisements, etc.; when the broadcast notification is needed, the data processing platform can broadcast the notification data.
And S220, the data processing platform analyzes the data content contained in the data report message according to the data report information obtained by analyzing the report registration line.
Data report statements, describing the data content and formatting rules of a report, require parsing of a data report line (i.e., a data report message) according to the rule description reporting the registration report data of the registration line in the registration statement, and a data report statement is capable of reporting one or more data. The reported data content may include: data type, data value, data attribute, data description and the like.

(4) Other data reporting services; such as reporting traffic describing current configuration data, historical data, etc.
Data reporting business application scenarios and data types include, but are not limited to:
(1) and reporting the monitored data when the monitoring terminal reaches a reporting period.
(2) When the monitoring and monitoring terminal monitors that the environmental parameters or the production safety indexes exceed the alarm threshold, alarm data can be reported.
(3) After the terminal is restarted, the current configuration data can be reported.
(4) When the communication contact terminal has the requirement of reporting the lottery/short message, the lottery/short message data can be reported.
(5) When the terminal works and gives an alarm, the terminal can report related alarm information to the data processing platform.
(6) When the audio and video data interaction requirement exists, the collected monitoring image or video and voice service can be reported (the terminal and the data processing platform may have the requirement).
(7) When the communication contact data processing platform has the requirement of issuing the lottery/short message, the lottery/short message data can be issued to the terminal.

(9) The system broadcasts the announceable data when there is a need to broadcast announcements.
(10) When the data processing platform has a requirement for remote adjustment of the terminal, a remote adjustment instruction can be issued to the terminal; and simultaneously, the terminal can report the calibration data to the data processing platform. The data types related to the description of the remote tuning service include zero tuning, precision tuning, alarm point tuning and the like. The remote tuning service description comprises the description of the data processing platform on the remote tuning operation of the terminal, the description of the calibration data periodically reported by the terminal, and the description of the intermediate tuning operation which is issued for many times after the data processing platform calculates according to the calibration data reported by the terminal.
The service description issued for data in the data report service description is not suitable for a terminal without a receiving function, that is, a unidirectional terminal only supporting uplink capability. For example, some positioning terminals or sensor terminals support only one-way devices for transmitting data, and are not suitable for parameter configuration operation.
For the aforementioned example of the registration statement, a description of reporting service in a temperature and gas cycle is correspondingly given. In the following example of a data report statement for reporting monitoring data periodically, it is assumed that temperature and gas monitoring data are reported in the same period, and the data report statement includes a service description syntax specification version, a statement type (data report statement) and specific reported data content, which are followed by the statement.
The data report statement example is as follows:
StatementInfo 1.0 DRS; (service description syntax version number 1.0; statement type DRS (data reporting statement));
DataReport MR 3.826.6; (report name: MR; data reported this time: gas concentration: 3.8%; temperature: 26.6 ℃ (assuming that the order of parameters in the report registration line is gas concentration, temperature)).
In the mine safety production Internet of things, the data processing platform can carry out remote management operation on the terminal, and the data processing platform can send a management message to the terminal to realize the remote management operation on the terminal.

s310, the data processing platform packages the management message according to the first preset format.
And the management statement (namely, the management message) is used for describing the remote management operation information of the data processing platform to the terminal. The command line type in the management message is one of an operation type, an operation response type and an upgrade type. That is, the management statement includes an operation statement, an operation response statement, and an upgrade statement.
Specifically, the data processing platform obtains a line keyword of a command line of the management message according to the type of the management message; then, according to the management object, or the management object and the object content, obtaining the data item of the command line of the management message; and encapsulating the command line of the management message into the management message.
Some management operations do not need object content, and the terminal analyzes a management service command line of a management statement to obtain a management object, for example, a restart statement "Reboot", which is a restart operation parameter name, i.e., a management object; in another example, a factory Reset statement "Reset" is a factory Reset operation parameter name.
S320, the data processing platform sends the management message to the terminal so that the terminal executes corresponding management operation according to the management message.
