Description

Technical Field

[0001] The utility model relates to the technical field of underground mine monitoring, in particular to a long-distance data transmission system between an underground environment monitoring sensor and a base station. Background Art

[0002] The sensors used in the underground environmental monitoring system of mining enterprises are connected to the sensor base station through RS485 communication cables. Each sensor base station can be connected to 8 sensor interfaces (generally only 3-5 are used). If a sensor needs to be installed somewhere underground due to production safety, laying communication cables to other sensor base stations in use will result in long distances, poor anti-interference capabilities, and unstable signal transmission; if the sensor base station is installed nearby, this will increase costs and cause unnecessary waste, and the difficulty of installation and construction will also increase. Based on this, this application proposes a long-distance data transmission system between underground environmental monitoring sensors and base stations. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a long-distance data transmission system between an underground environment monitoring sensor and a base station. Two 485-to-Ethernet serial port servers are used to transmit the sensor data over a long distance through a TCP / IP network, which saves costs, reduces construction difficulty, and improves the anti-interference and stability of data transmission. Similarly, the present application is also applicable to other occasions where serial port devices are required to transmit data over long distances.

[0004] The long-distance data transmission system between underground environment monitoring sensors and base stations in this solution is suitable for scenarios where new sensors are installed and data is transmitted to sensor base stations over long distances. It includes a transmitting serial port server, a receiving serial port server, a sensor base station and at least one sensor (a serial port server can be connected to multiple sensors as needed). The transmitting serial port server and the receiving serial port server are respectively connected to the Ethernet through the first network port cable and the second network port cable, the receiving serial port server is connected to the sensor base station through the second 485 serial port cable, and the sensors are all connected to the transmitting serial port server through the first 485 serial port cable. It aims to make full use of the unused interfaces of the sensor base station of the underground mine monitoring system, reduce safety production costs, solve the problem of data transmission stability, and use a 485 converter for transmission through the TCP / IP network.

[0005] The technical solution further defined in the utility model is:

[0006] Furthermore, the network ports of the transmitting end serial device server and the receiving end serial device server are configured in the same network segment, or are configured in an intercommunication state under different VLANs.

[0007] Furthermore, the transmitting end serial port server and / or the receiving end serial port server is a 485 converter.

[0008] Furthermore, the first network port cable and / or the second network port cable is an RJ45 network cable.

[0009] Furthermore, the sensor includes at least one of a methane sensor, a carbon monoxide sensor, a temperature sensor, a wind speed sensor, a smoke sensor and an oxygen sensor.

[0010] The beneficial effects of the utility model are as follows: the utility model adopts two 485-to-Ethernet serial port servers to transmit sensor data over long distances through a TCP / IP network, which is suitable for scenarios where new sensors are installed and data is transmitted to a sensor base station over long distances. It cleverly utilizes unused interfaces of sensor base stations that have been put into operation to achieve the function of installing new sensors without installing new sensor base stations and transmitting data over long distances, thereby achieving the effect of saving costs, reducing construction difficulty, and improving the anti-interference and stability of data transmission.

[0012] Among them: 1. Sensor; 2. Sensor base station; 3. Transmitter serial port server; 4. Receiving serial port server; 5. First 485 serial port cable; 6. Second 485 serial port cable; 7. First network port cable; 8. Second network port cable. DETAILED DESCRIPTION

[0013] like Figure 1 As shown, the long-distance data transmission system between the underground environment monitoring sensor and the base station provided by the present embodiment includes a transmitting end serial port server 3, a receiving end serial port server 4, a sensor base station 2 and a sensor 1. The transmitting end serial port server 3 and the receiving end serial port server 4 are connected to the Ethernet through the first network port cable 7 and the second network port cable 8 respectively, the receiving end serial port server 4 is connected to the sensor base station 2 through the second 485 serial port cable 6, and the sensor 1 is connected to the transmitting end serial port server 3 through the first 485 serial port cable 5, and the network ports of the transmitting end serial port server 3 and the receiving end serial port server 4 are configured in the same network segment.

[0014] In this embodiment, both the transmitting end serial device server 3 and the receiving end serial device server 4 are 485 converters, and both the first network port cable 7 and the second network port cable 8 are RJ45 network cables.

[0015] This application is aimed at the situation where a sensor needs to be installed somewhere underground for safety production. If a sensor base station is installed nearby, it will increase the cost and cause unnecessary waste, and the difficulty of installation and construction will also increase. Now two 485 converters (the cost of this equipment is about 1 / 40 of the sensor base station) are used to transmit through the TCP / IP network to solve the problem of direct connection between a sensor and any sensor base station in use, ensuring the stability of data transmission, reducing the difficulty of construction, and reducing costs.

[0016] The installation process of this embodiment is as follows: first, install an RS485 to Ethernet serial port server next to the sensor 1, and connect the sensor 1 to the 485 terminal of the serial port server. The serial port server is named as the transmitter, i.e. the transmitter serial port server 3, and the network port of the transmitter is connected to the Ethernet with a network cable; install a serial port server of the same type next to the sensor base station 2 where the interface is not used, and name it the receiver, i.e. the receiver serial port server 4. Connect the 485 terminal of the receiver to the 485 terminal of the sensor base station 2, and connect the network port of the receiver to the Ethernet with a network cable; configure the network ports of the two serial port servers in the same network segment or under different VLANs (VLANs are adjusted to communicate with each other) to complete the installation.

[0017] Specifically, this embodiment provides a new method for 485-to-Ethernet data transmission, which is a solution for long-distance transmission of 485 data in mines. Two 485-to-Ethernet serial port servers are used to transmit sensor data over a TCP / IP network over long distances, saving costs, reducing construction difficulty, and improving the anti-interference and stability of data transmission. Similarly, this application is also applicable to other occasions that require serial port devices to transmit data over long distances.

[0018] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
