In addition, it should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other; for convenience of description, only parts related to the invention are shown in the drawings.
Example 1
Fig. 1 is a flow chart of a transmission method of field monitoring data in an embodiment of the present application, as shown in fig. 1, where the transmission method of field monitoring data in this embodiment is applied to a data acquisition terminal of a natural gas pipe network operation system, the data acquisition terminal is an intrinsic safety type terminal powered by a lithium battery, and the terminal is in wireless communication connection with an operation center server, and the method includes:
s10, periodically acquiring monitoring data acquired by each sensor at the same time in a wired connection range by a data acquisition terminal;

and S50, periodically transmitting an uploading data packet to the operation center server by the data acquisition terminal, wherein the uploading data packet is used for analyzing and obtaining monitoring data acquired by each sensor by the operation center server based on software information of the pre-stored data acquisition terminal.
The transmission method of the on-site monitoring data can improve the transmission efficiency of the monitoring data and effectively reduce the maintenance cost caused by the replacement of the battery by the terminal.
In order to better understand the present invention, each step in this embodiment is explained below.
In step S10, in this embodiment, the wireless communication connection between the data acquisition terminal and the operation center server may be 3G/4G/5G/cellular-based narrowband internet of things (Narrow Band Internet ofThings, NB-loT), and the corresponding data acquisition terminal identification information may be an international mobile equipment identification code (International Mobile Equipment Identity, IMEI).
The period length may be, for example, 2 minutes, 5 minutes, or other preset period.
In step S20, the sensor relative position information set includes a low voltage end, a medium voltage end, and a high voltage end. The data block is composed of 6 bytes, the first byte is used for identifying the type of the sensor, the second byte is used for identifying the relative position information of the sensor, and the four following bytes are used for carrying monitoring data collected by the sensor.
In step S30, the core data packet adopts a fixed data format, where the data format is: the number of data blocks, the number of data blocks and the acquisition time,
in particular, the acquisition time is a timestamp in the sensor data, and since the acquisition time of each data block is completely uniform, the last timestamp is also common.
In this embodiment, the sensor may include a wireless gas detector, a flow meter, a pressure gauge, a thermometer, or the like.
In step S40, the identification information of the data acquisition terminal is IMEI number, the functional identification information of the data packet is command code, the uploaded data packet further includes a data packet number, and the data packet number is the serial number of the uploaded data packet in a preset time period; the data format of the uploading data packet is as follows: header, data packet number, IMEI number, command code, data field, check bit, and trailer; the data field is used for bearing a plurality of core data packets and the quantity information of the core data packets.
The packet number is 4 bytes and all upstream data, information or requests are incremented in unison, with the upstream packet numbers cycling between 0x00000000 and 0x7 FFFFFFF. The transmission fails, and the data packet number is not incremented.
By means of the data packet numbering, only the failed data packet is required to be retransmitted when the data transmission fails, and the data transmission efficiency is improved.
Specifically, the format of the data packet is: header + packet number + IMEI number + command code + data field + check + trailer.
Wherein, the command codes are feature codes of each data packet, the data packets with different functions and the command codes are different.
The data field adopts a chapter structure, and one data packet can transmit a plurality of core data packets. For example, if collected once for 5 minutes, uploaded once for 1 hour. And adding a common time stamp to all the data of temperature, pressure, flow, components and the like acquired at the same time to form a core data packet. In the conventional communication, the data field is formed by two parts of data length and data field, the acquisition time stamp can only be at the tail, otherwise, the acquisition data and the time stamp cannot be separated, so that each data packet can only transmit one core data packet, 12 data packets are needed to transmit the data acquired within 1 hour, the meaning of one byte of data Bao Nadi in the embodiment is how many core data packets, and the format of each core data packet is fixed, so that the data acquired within 1 hour only needs one data packet to transmit. The length of the data packet is longer, but a large number of bytes such as a header, a tail, a data packet number, an IMEI number, a function number, a check code and the like are saved.
In step S50, the transmission period of the upload packet is longer than the data acquisition period in step S10.
In this example, the sample was collected once for 5 minutes and uploaded once for 1 hour.
The operation center server is pre-stored with software information of the data acquisition terminal which is bound with the identification information of the data acquisition terminal, and can also pre-store corresponding hardware information, wherein the software information of the data acquisition terminal can be a software version number, and the hardware information can be a terminal type and a provider ID.
The software information and the hardware information pre-stored in the operation center server can be stored when the data acquisition terminal is installed, specifically: when equipment is installed, the terminal and the acquisition point are bound by the two-dimension code, and the two-dimension code format is as follows:
IMEI: standby: terminal type: vendor ID: standby: software version number.
And then the bound information is written into a parameter configuration table of the central server at one time.
In this embodiment, when the software information bound with the identification information of the data acquisition terminal is changed, the method further includes:
responding to the triggering operation of a user, and encapsulating a plurality of adjacent core data packets, changed software information and data acquisition terminal identification information by the data acquisition terminal to obtain an information update data packet;
the data acquisition terminal sends an information update data packet to the operation center server, wherein the information update data packet is used for updating software information bound with the identification information of the data acquisition terminal by the operation center server.
Specifically, a manual button is arranged on the terminal, and when the manual button is triggered, a data packet with the following format is uploaded:
header + IMEI number + command code + software version number + data field + checksum + trailer.
It should be noted that, when the terminal equipment is operating normally, the software information will not be changed, where the software information change refers to that the terminal is updated in the field, and after the update, the manual button triggers the terminal to upload to make protocol synchronization.
In this embodiment, the plurality of core packets in the upload period are encrypted by the RC4 encryption algorithm.
Preferably, the method may further comprise:
the data acquisition terminal receives an inquiry request data packet sent by an operation center server, and information packaged by the information inquiry data packet comprises identification information of the data acquisition terminal and inquiry content information;
the data acquisition terminal encapsulates the feedback information and the data acquisition terminal identification information to obtain a request response data packet;
and the data acquisition terminal sends the request response data packet to the operation center server.
Specifically, the center may initiate a query in the format of: header + IMEI number + command code + challenge content + checksum + trailer.
The terminal will answer one by one according to the content of the query, which may include:
the method comprises the following steps of 22 types of information, such as battery voltage, signal strength, equipment information, device information, explosion-proof and waterproof information, acquisition time interval, uploading starting limit, uploading starting frame, zero drift, inclined drift, uploading initial inclined angle, geographical position information, impact acceleration threshold value, overpressure upper limit, overpressure lower limit, under-voltage upper limit, under-voltage lower limit, temperature upper limit, temperature lower limit, battery under-voltage threshold value, inclination threshold value and the like. The voltage measured when the battery voltage is the central upper computer inquires is obtained by reading the signal strength from the terminal communication module, and other information is obtained by reading the signal strength from a FLASH memory (FLASH).
Preferably, the method further comprises:
when the data acquisition terminal detects that the monitoring data of the upper and lower pressure limits, the upper and lower temperature limits or the battery under-voltage exceeds the preset times of the alarm line, alarm class information, corresponding monitoring data and relative position information of the sensor form alarm data;
the data acquisition terminal verifies and encapsulates the alarm data, the data acquisition terminal identification information of the current data acquisition terminal and the data packet function identification information to obtain an alarm data packet;
and the data acquisition terminal sends the alarm data packet to the operation center server.
Because the intrinsically safe terminals are battery powered, the communication consumption largely determines the battery life. Compared with the prior art, the software version number and the terminal type in the embodiment are not transmitted in the data packet transmitted each time, the non-effective data in the data packet is compressed on the premise of ensuring more complete data, the duty ratio of the effective data in the data packet is improved, so that more effective data can be transmitted to the center platform in the same battery in the service life period, and the maintenance cost of the terminal equipment caused by frequent battery replacement is reduced.
