Description

Technical Field

[0001] The utility model relates to the technical field of boiler natural gas transmission, in particular to a natural gas data transmission system for boilers in tobacco plants. Background Art

[0002] Since the gas metering link is maintained and managed by the gas supplier, the data link is uploaded to the gas supplier's server through a third-party GPRS gateway installed at the meter head. This means that tobacco companies can only obtain gas metering data by accessing the non-local cloud server set up by the gas supplier through the Internet.

[0003] Changes in the internet environment are severely impacting tobacco companies' gas data collection. With the increasing security standards for industrial intranets, the traditional practice of tobacco companies' intranet servers accessing the external network has come into conflict with industrial intranet security regulations. To ensure the secure and stable collection of natural gas data by tobacco companies while ensuring the security of industrial intranets, the industry urgently needs to upgrade existing natural gas data collection links. For example, this utility model explores a feasible solution for tobacco companies to shift their natural gas data collection from the external network to the internal network. Utility Model Content

[0004] In view of the above, the present invention aims to provide a natural gas data transmission system for a tobacco factory boiler to solve the above-mentioned technical problems.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] The utility model provides a natural gas data transmission system for a tobacco factory boiler, which comprises: an industrial wireless transparent transmission device arranged at a natural gas meter, a wireless relay device arranged in an area between the natural gas meter and a data acquisition machine room, a data acquisition server, a switch, and a host computer of a boiler control system; wherein the data of the natural gas meter is transmitted to the data acquisition machine room through the industrial wireless transparent transmission device and the wireless relay device; the data acquisition machine room sends the natural gas data to the switch, and the switch transmits the data to the data acquisition server, and the natural gas data interface of the host computer is connected to the data acquisition server to obtain the natural gas data.

[0007] In at least one possible implementation manner, a wireless transceiver terminal is configured in the data acquisition room, and the wireless transceiver terminal is respectively electrically connected to the wireless relay device and the data acquisition cabinet.

[0008] In at least one possible implementation manner, the wireless transceiver terminal and the wireless relay device use two-way communication to send data acquisition requests to the meter end and obtain meter data from the meter end.

[0009] In at least one possible implementation, the data transmission system further includes: a PLC disposed in a data acquisition room or a data acquisition cabinet for decoding and re-encoding natural gas data.

[0010] In at least one possible implementation, the data acquisition cabinet in the data acquisition room sends the natural gas data to the switch via an intranet cable.

[0011] In at least one possible implementation manner, the intranet cable uses the TCP network protocol for transmission.

[0012] Compared with the existing technology, the main design concept of this utility model is to transmit gas meter data through mature industrial wireless transparent transmission technology. Due to the relatively scattered distribution of natural gas meters in the tobacco company and the obstruction of tall buildings in the factory, it is necessary to further solve the problem of unstable transmission of transparent transmission signals. Therefore, wireless relay technology is introduced to achieve stable wireless communication. For example, a set of wireless relay equipment is set up in a preset area for wireless communication with instruments and meters, which forwards the received instrument data to the wireless transceiver terminal of the data acquisition cabinet. The wireless transceiver terminal of the data acquisition cabinet can also send collection instructions to the wireless transparent transmission device at the instrument end. In addition, the data acquisition cabinet uses industrial Ethernet and other methods to send data to the tobacco company's server through a switch. In this way, the boiler control host computer can obtain natural gas data from the server on demand, thereby meeting the needs of natural gas meter data transmission on the intranet. By transforming the natural gas data acquisition link from the external network to the internal network, this utility model greatly improves the stability of natural gas data acquisition in the tobacco company, effectively avoiding the problem of frequent interruptions of natural gas data acquisition caused by external network factors, and transmitting through the internal network, no longer relying on the port to the Internet, which can effectively improve the security of the industrial control network environment.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0016] This utility model proposes an embodiment of a natural gas data transmission system for a tobacco plant boiler. Specifically, Figure 1 As shown, it includes: an industrial wireless transparent transmission device 2 set at the natural gas meter 1, a wireless relay device 3 set in the area between the natural gas meter 1 and the data acquisition room, a data acquisition server 6, a switch 7 and a host computer 8 of the boiler control system; wherein, the data of the natural gas meter 1 is transmitted to the data acquisition room through the industrial wireless transparent transmission device 2 and the wireless relay device 3, and the data acquisition room sends the natural gas data to the switch 7 through the intranet cable, and the switch 7 transmits it to the data acquisition server 6, and the natural gas data interface of the host computer 8 is connected to the data acquisition server 6 to obtain the natural gas data.

[0017] Based on this embodiment, it can be further expanded that a wireless transceiver terminal 4 is configured in the data acquisition room, and the wireless transceiver terminal 4 communicates data with the wireless relay device 3 and the data acquisition cabinet 5 respectively.

[0018] The data of the natural gas fuel meter 1 is sent out through the industrial wireless transparent transmission device 2 and forwarded by the wireless relay device 3. The data acquisition cabinet 5 in the data acquisition room uses the local wireless transceiver terminal 4 to stably communicate with the wireless relay device 3, and the data acquisition cabinet 5 can (in some preferred embodiments, a PLC can also be set in the data acquisition cabinet 5 to decode and re-encode the natural gas data in transmission) transmit the data through the established network protocol (TCP) to the switch 7 located in the power center of the plant. After the data acquisition server 6 obtains the data through the switch 7, it can be sent to the host computer 8 of the boiler control system. The above data link realizes the stable transmission of the natural gas meter data in the intranet.

[0019] In summary, the main design concept of the present invention is to transmit gas meter data through mature industrial wireless transparent transmission technology.
