Description

Technical Field

[0001] The utility model relates to the technical field of data transmission, in particular to a data transmission device for underground roadways in mines. Background Art

[0002] The safety problem of underground roadways in mines has always been a concern for technicians in this field. Technicians need to analyze and process the data in the roadways to judge the safety conditions of the roadways. Over the years, due to problems such as irregular operations in the roadways, failure to detect or report potential safety hazards in a timely manner, accidents have occurred frequently, not only causing huge economic and social losses, but also bringing great pressure to on-site safety production operations.

[0003] Currently, terminal devices are deployed inside the underground roadways in mines for data collection, and the collected data is transmitted to the control center through a sending device. The control center analyzes, processes, and stores the collected data. In some areas of the underground roadways in mines, when multi-type data such as spot checks, patrol inspections, and operation and maintenance gather in one place, since the terminal devices collect a large amount of data, it will lead to a reduction in data transmission efficiency. Furthermore, it will cause the collected data to not be uploaded to the control center in real time, thus delaying the data monitoring of important types of work. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: to solve the technical problem that when the existing terminal devices collect a large amount of data and transmit it to the control center in real time, it will lead to a reduction in data transmission efficiency. The utility model provides a data transmission device for underground roadways in mines. By improving the structure of the data transmission device, the data transmission efficiency can be improved.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a data transmission device for underground roadways in mines, including: a collection module, a sending module, a data storage module, an MCU processing module, and a control center. The collection module includes: a first collection sub-module and a second collection sub-module. The first collection sub-module and the second collection sub-module are both installed in the underground roadways in mines. The first collection sub-module is connected to the sending module, the second collection sub-module is connected to the data storage module, the data storage module is connected to the MCU processing module, the MCU processing module is connected to the sending module, and the sending module is connected to the control center.

[0006] Thus, the data collected by the first acquisition sub-module is sent to the control center in real time through the sending module, and the data collected by the second acquisition sub-module is stored in the data storage module and sent to the control center regularly through the MCU processing module. Compared with the existing transmission method in which all the collected data is directly sent to the control center, this method can classify and process the collected data to achieve segmented data transmission, avoid affecting the data transmission efficiency due to a large amount of data to be transmitted, and further ensure that the data collected by the first acquisition sub-module is transmitted to the control center in real time, thus not delaying the data monitoring of important work types.

[0007] Furthermore, the first acquisition sub-module is used to collect data of the underground roadway in the mine in real time, and multiple first acquisition sub-modules are provided.

[0008] Furthermore, the second acquisition sub-module is used to collect data of the underground roadway in the mine regularly, and multiple second acquisition sub-modules are provided.

[0009] Furthermore, the MCU processing module includes: a timer, a DMA, and an ADC. The ADC is connected to the data storage module and the timer, the data storage module is connected to the DMA, and the DMA is connected to the sending module. Thus, through the mutual cooperation of the timer, DMA, and ADC, the data collected by the second acquisition sub-module is temporarily stored in the data storage module and sent to the control center regularly through the sending module.

[0010] Furthermore, it also includes: a power supply module. The first acquisition sub-module, the second acquisition sub-module, the sending module, the data storage module, the timer, and the DMA are all connected to the power supply module. Thus, it can supply power to the entire data transmission device to ensure the normal operation of the entire data transmission device.

[0011] Furthermore, the sending module includes: chip U1, and chip U1 adopts LoRa spread spectrum technology.

[0012] Furthermore, the data storage module includes: chip U2, chip U3, chip JTAG, plug-in X1, and plug-in X2. The second acquisition sub-module, the timer, chip U2, chip JTAG, plug-in X1, and plug-in X2 are all connected to chip U3. Thus, it can store the data collected by the second acquisition sub-module in real time.

[0013] Furthermore, the model of the MCU processing module is STM32F407.

[0014] Further, the power supply module includes: plug X3, AD / DC switching power supply, capacitor C1, inductor L1, capacitor C2, chip N, capacitor C3, inductor L2, capacitor C4, capacitor C5, and resistor R. One end of plug X3, capacitor C1, and inductor L1 are all connected to the AC / DC power switch. The other end of inductor L1 and one end of capacitor C2 are both connected to the input terminal of chip N. One end of inductor L2 and capacitor C3 are both connected to the output terminal of chip N. One end of capacitor C4, capacitor C5, and resistor R are all connected to the other end of inductor L2.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] The data collected by the first acquisition sub-module is sent to the control center in real time through the sending module. The data collected by the second acquisition sub-module is stored in the data storage module and sent to the control center regularly through the MCU processing module. Compared with the transmission method in the prior art where all the collected data is directly sent to the control center, this method can classify and process the collected data to achieve the time-division transmission of data, avoid affecting the data transmission efficiency due to a large amount of data to be transmitted, and further ensure that the data collected by the first acquisition sub-module is transmitted to the control center in real time, thus not delaying the data monitoring of important work types.

[0029] Such as Figures 1 to 7As shown, it is the optimal embodiment of the present utility model. The data transmission device for the underground roadway in a mine in this embodiment includes: a collection module 1, a transmission module 2, a data storage module 3, an MCU processing module 4, and a control center 5. The collection module 1 includes: a first collection sub-module 101 and a second collection sub-module 102.

Thus, the data collected by the first collection sub-module 101 is sent to the control center 5 in real time through the transmission module 2. The data collected by the second collection sub-module 102 is stored in the data storage module 3 and sent to the control center 5 regularly through the MCU processing module 4. Compared with the existing transmission method in which all the collected data is directly sent to the control center 5, this method can classify the collected data to achieve the time-division transmission of the data, avoid affecting the data transmission efficiency due to the large amount of data to be transmitted, and further ensure that the data collected by the first collection sub-module 101 is transmitted to the control center 5 in real time, thus not delaying the data monitoring of important work types.

[0030] Specifically, the control center 5 refers to a central control platform integrating a server, application software, a display screen, etc., which can receive and process the data collected by the first collection sub-module 101 and the second collection sub-module 102, and reasonably apply these data.

[0032] In other words, important types of work data such as oxygen concentration data, carbon monoxide concentration data, and carbon dioxide concentration data in the underground roadway in the mine are sent to the control center 5 in real time, and non-important types of work data such as temperature data, humidity data, and data of the change in the surrounding rock structure in the underground roadway in the mine are sent to the control center 5 at regular intervals, avoiding the influence on the data transmission efficiency due to a large amount of data to be transmitted (that is, important types of work data are sent in real time, non-important types of work data are sent at regular intervals, and the data sent at the same moment will not be excessive), and thus ensuring that the data acquired by the first acquisition sub-module 101 is transmitted to the control center 5 in real time, so as not to delay the data monitoring of important types of work.

[0033] In this embodiment, the sending module 2 includes: a chip U1, and the chip U1 adopts LoRa spread spectrum technology.

[0037] For example, chip U2 can be an SD card, with a storage format of CSV format, capable of storing the data acquired by the second acquisition sub-module 102 into the SD card. The model of chip U2 is STM32F103VET6, the model of chip JTAG is BH254V-20P, the model of plug-in X1 is KF301-4P, and the model of plug-in X2 is PZ254V-11-02P.

[0039] Specifically, the MCU processing module 4 may adopt but is not limited to STM32F407, NS32F407, STM32F417, as long as it can meet the function of sending the data in the data storage module 3 at regular intervals.

[0040] Specifically, through the mutual cooperation of the timer 401 and the DMA402, the data can be automatically transferred from the data storage module 3 to the sending module 2 at a set time interval (for example: the temperature data and humidity data are set to be transmitted once every 1 hour or 2 hours, and the data on the change of the surrounding rock structure is set to be transmitted once every half a month or a month), and the data is transmitted to the control center 5 through the sending module 2.

[0042] In this embodiment, it further includes: a power supply module 6, and the first acquisition sub-module 101, the second acquisition sub-module 102, the sending module 2, the data storage module 3, the timer 401 and the DMA 402 are all connected to the power supply module 6; the power supply module 6 includes: a plug X3, an AC / DC switching power supply, a capacitor C1, an inductor L1, a capacitor C2, a chip N, a capacitor C3, an inductor L2, a capacitor C4, a capacitor C5 and a resistor R.

One end of the inductor L2 and one end of the capacitor C3 are connected to the output end of the chip N. One end of the capacitor C4, the capacitor C5 and the resistor R are all connected to the other end of the inductor L2. Thus, it can supply power to the entire data transmission device to ensure the normal operation of the entire data transmission device.

[0043] Specifically, the other end of the AC / DC switching power supply, the other end of the capacitor C1, the other end of the capacitor C2, the grounding end of the chip N, the other end of the capacitor C3, the other end of the capacitor C4 and the other end of the capacitor C5 are all grounded.

[0044] The data transmission process of the present utility model is as follows: First, start the power supply module 6 to supply power to the entire data transmission device so that the entire data transmission device operates normally; then, the data collected by the first acquisition sub-module 101 is transmitted to the management and control center 5 in real time through the sending module 2, and the data collected by the second acquisition sub-module 102 is stored in the data storage module 3, and under the cooperation of the timer 401, the DMA 402 and the ADC 403, it is transmitted to the management and control center 5 at regular intervals through the sending module 2 according to the set time interval.
