[0024] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0025] The acquisition, storage, use, and processing of data in the technical solution disclosed in this disclosure are in compliance with the relevant provisions of relevant laws and regulations.

[0026] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be considered as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0027] The present disclosure provides a mining monitoring substation, which is a lower-level device of a monitoring system. The monitoring system may include multiple mining monitoring substations. It should be noted that there may be communication connections between the mining monitoring substations in the embodiments of the present disclosure. The monitoring system is used to aggregate the data of all mining monitoring substations and perform overall control and early warning.

[0028] Figure 1 is a schematic diagram of a mining monitoring substation according to an embodiment of the present disclosure, such as Figure 1 As shown, the mining monitoring substation 100 includes: an energy module 110 , a communication module 120 , a sampling module 130 and a control module 140 .

[0029] The energy module 110 includes a power storage device and a power direct supply device, which are used to provide power for other modules of the mining monitoring substation.

[0030] In current technology, the power supply of the mine monitoring substation is powered by a DC power supply of the mine intrinsically safe power supply. Since the intrinsically safe power supply and the mine monitoring substation are not in the same location, a power supply cable with a certain distance is required. When a large energy load is in operation under the substation, the line power supply current will temporarily increase, causing the line voltage to fluctuate, and in severe cases, the line will be powered off.

[0031] In order to solve this problem, the present disclosure proposes that in addition to the conventional direct power supply device, a power storage device is also added to perform auxiliary functions when the direct power supply device is insufficient, so as to ensure the normal working voltage of the mine monitoring substation and increase the stability of underground monitoring work and the safety of underground operations. For example, for the mine monitoring substation in the current technology, assuming that the bus can power 4 mine monitoring substations, assuming that the working voltage of the fourth mine monitoring substation at the end is at the lowest working voltage of 7V, its working current is 1W / 7V=0.143A; the working voltage at the third mine monitoring substation is 7V+0.143A*12R=8.7V, and its working current is 1W / 8.7V=0.115A; the working voltage at the second mine monitoring substation is 8.7V+(0.143A+0.115A)*1 2R=11.8V, and its working current is 1W / 11.8V=0.085A; the working voltage at the first mining monitoring substation is 11.8V+(0.143A+0.115A+0.085A)*12R=15.9V, and its working current is 1W / 15.9V=0.062A; then the output voltage of the intrinsically safe power supply is required to be 15.9V+(0.143A+0.115A+0.085A+0.062A)*12R=20.76V, and it is obvious that the 18V intrinsically safe power supply cannot be used.

[0032] If the mining monitoring substation disclosed in the present invention is used, assuming that the working current of the fourth mining monitoring substation is i, and 18V is powered by a 500-meter line, then the substation working voltage*substation working current=(18V-12R*i)*i=1W, then the working current i=0.06A; assuming that the working current of the third mining monitoring substation is i, then (18V-12R*i)*i=2W+12R*0.06A^2, i= 0.124A; Assuming the working current of the second mining monitoring substation is i, then (18V-12R*i)*i=3W+12R*0.184A^2, i=0.222A; Assuming the working current of the first mining monitoring substation is i, then (18V-12R*i)*i=4W+12R*0.406A^2, i=0.496A; 1 18V-0.9A intrinsically safe power supply has met the line requirements.

[0033] It can be seen from the above embodiments that the mining monitoring substation disclosed in the present invention can greatly reduce the requirements for the direct power supply device, and can reduce the equipment cost and the space occupied by the equipment.

[0034] The sampling module 130 includes a high-frequency sampling device and a low-frequency sampling device, which are used to collect underground environmental data and equipment operation data.

[0035] In current technology, the mining monitoring substations of the monitoring system are generally single-second or millisecond sampling system equipment. However, due to the need for data fusion of multiple monitoring systems in the construction of intelligent mines, especially when the monitoring system with millisecond sampling needs to be analyzed collaboratively with other second-level monitoring systems, how to achieve synchronous sampling of multiple acquisition devices is the first problem that needs to be solved.

[0036] In order to solve this problem, the sampling module 130 proposed in the present disclosure includes a high-frequency sampling device and a low-frequency sampling device, so as to achieve better monitoring of underground operations.

[0037] In the embodiments of the present disclosure, the high-frequency sampling device and the low-frequency sampling device may include a variety of devices, which are not limited here. They may be limited according to actual sampling requirements. For example, the high-frequency sampling device and the low-frequency sampling device may be an image acquisition device, a gas concentration sampling device, etc.

[0038] The communication module 120 is used to perform information exchange with the high-frequency sampling device and / or the low-frequency sampling device through a local sampling timestamp synchronization method.

[0039] The essence of the time synchronization of mining monitoring substations in current technology is to synchronize the local sampling timestamps of each device. This requires synchronizing the local time of each device before sampling data and uploading the sampling data and sampling timestamps, so as to achieve sampling time synchronization of different devices. Each device needs to use a high-precision crystal oscillator to build a local clock. This time synchronization method will increase communication delay, especially in complex working conditions such as underground, where communication delay may increase exponentially.

[0040] In order to solve this problem, the present disclosure proposes a method for information exchange with a high-frequency sampling device and / or a low-frequency sampling device through local sampling timestamp synchronization. There is no need to wait for local time synchronization, and there is no need to use a high-precision crystal oscillator to build a local clock locally, which eliminates the time for establishing synchronization and reduces hardware costs.

[0041] The control module 140 is used to receive the environmental data and equipment operation data collected by the sampling module 130, and generate control instructions according to the environmental data and equipment operation data. It should be noted that the control module 140 in the embodiment of the present disclosure can be of various types, and no limitation is made here.

[0042] In another possible implementation, the control module 140 may also include a storage device for storing environmental data and equipment operation data.

[0043] Therefore, by monitoring underground construction through the mining monitoring substation disclosed in the present invention, the normal operating voltage of the mining monitoring substation can be ensured, the stability of underground monitoring work and the safety of underground operations can be increased, and at the same time, the time for establishing synchronization is eliminated through the local sampling timestamp synchronization method, thereby reducing hardware costs.

[0044] In one possible implementation, the control module 140 can be connected to a local area network or the World Wide Web, so that underground data can be quickly interacted and displayed with the outside world. For example, the mining monitoring substation in this solution can be connected to the underground industrial ring network to transmit data to the upper computer on the ground.

[0045] In the above embodiment, the local sampling timestamp synchronization method is used to send information to other mining monitoring substations, and the local sampling timestamp synchronization method is used to send information to other mining monitoring substations. Figure 2 Explaining further, the method includes:

[0046] S201, obtaining a local timestamp.

[0047] It should be noted that in order to reduce the size of the local timestamp in the transmitted data, in the embodiment of the present disclosure, after obtaining the local timestamp, the local timestamp can be preprocessed. For example, the microsecond time information of the current master clock device can be obtained. The microsecond time information sent by the master clock is the microsecond value information calculated from zero o'clock today, which only requires 4 bytes and has a minimum resolution of 31.25 microseconds. The slave clock device, that is, the sensor device, can calibrate the sampling frequency of each device according to the time interval between two times to synchronize the number of sampling times. Moreover, since the mining monitoring substation sends synchronization information in a single step, the loss of synchronization information in a certain second does not affect the sampling in the next second. The sensor device can continue to sample and upload data according to the last calculated sampling interval.

[0048] S202: Generate a data request instruction based on the local timestamp, and send the request instruction to the high-frequency sampling device and / or the low-frequency sampling device.

[0049] In the embodiment of the present disclosure, after receiving the request instruction, the high-frequency sampling device and / or the low-frequency sampling device can obtain the local timestamp in the request instruction, and then generate target acquisition data based on the acquisition data of the high-frequency sampling device and / or the low-frequency sampling device and the local timestamp, and send it to the control module 140.

[0050] For example, if Figure 3 As shown, Figure 3 This is an example diagram of information interaction between a mining monitoring substation and a sensor disclosed in the present invention, such as Figure 3 As shown, the #2 underground substation broadcasts and sends s1 data at time t0, and the s1 data includes the microsecond time of the current time t1. Since the #2 underground substation has the highest transmission priority ID in the CAN bus, the data sent will be sent to the CAN bus first. The #3 sensor device receives the data broadcasted by the #2 underground substation at time t1, and after unpacking, adds the S1-1 data including the microsecond time of time t1 to the CAN upload data queue. Since the CAN bus of the #3 sensor device has a first-in-first-out mechanism for sending data and an automatic retransmission mechanism for unsuccessful sending, the data sent by the #3 sensor device received by the #2 underground substation is the S1-1 response data and the n sampling data from S21 to S2n in sequence. The #2 underground substation broadcasts and sends s1 data again at time t2, and the s1 data includes the microsecond time of the current time t2. At t3, the #3 sensor device receives the data broadcasted by the #2 underground substation. After unpacking, it adds the S1-1 data including the microsecond time at t2 to the CAN upload data queue. At the same time, it determines whether the next sampling interval needs to be corrected based on whether the last sampling number n divided by (t2-t1) is consistent with the required sampling frequency. In the communication process, the interval between t0 and t2 is strictly 1 second, and the error is controlled in microseconds, which can ensure the system's 0.5 millisecond sampling accuracy.

[0051] The s1 data is the request data, which is used to send a local timestamp to the high-frequency sampling device and / or the low-frequency sampling device.

[0052] In a possible implementation, the target collected data can be generated by combining the collected data of the high-frequency sampling device and / or the low-frequency sampling device and the local timestamp through a preset adding rule. The adding rule is designed in advance, for example, the local timestamp can be added to the last bit or a specified bit of the data to be sent.

[0053] In a possible implementation, the local timestamp and the data to be sent can also be processed by a target data generation model to generate target data. The target data generation model is trained in advance and can be stored in the storage space of the electronic device to facilitate retrieval and use when needed.

[0054] In the disclosed embodiment, the data to be sent and the local timestamp of the mining monitoring substation sending the data to be sent are first obtained, and then the target sending data is generated based on the local timestamp and the data to be sent, and the target sending data is sent to other mining monitoring substations. In this way, there is no need to synchronize time with the sender, the time for establishing synchronization is eliminated, and the hardware cost is reduced.

[0055] When receiving information from other mining monitoring substations through the method of local sampling timestamp synchronization, the sending data sent by other mining monitoring substations can be received first, and then the sending local timestamp in the sending data can be obtained, and the sending data can be spliced ​​based on the order of the sending local timestamps to generate target data.

[0056] In the disclosed embodiment, the communication module 120 transmits data via the CAN bus, and the transmission priority of the data sent by the communication module 120 is higher than other data transmitted on the CAN bus. The communication module 120 includes a millisecond sampling device interface and a second sampling device interface. For example, the mining monitoring substation in this scheme may have a millisecond sampling device interface (two 500kbps communication rate CAN interfaces) for the bottom sampling device, and may also have a second sampling device interface (one 2500bps communication rate CAN interface), and broadcast the synchronization time information every second so that the sampling time of the second and millisecond sampling devices has a unified time accuracy.

[0057] The current technology for powering underground coal mine monitoring equipment mostly adopts bus power supply, where one intrinsically safe power supply carries multiple devices. Due to power line loss, when supplying power over long distances, the line voltage drops, causing the monitoring equipment to fail to start.

[0058] In order to solve the above problem, the energy module 110 of the present disclosure further includes: a boost circuit for boosting the output voltage of the power storage device and the power supply device to a set voltage and then transmitting it to other modules. In this way, the problem that the monitoring device cannot start due to the line voltage reduction can be solved.

[0059] In one possible implementation, the power storage device is a supercapacitor, and the supercapacitor is used to provide a compensation voltage for the mining monitoring substation after the output voltage of the direct power supply device is lower than a set value.

[0060] In the disclosed embodiment, the mining monitoring substation further includes: a display module, and the display module is used to display environmental data and equipment operation data.

[0061] In a possible implementation, the display module may also include an ink display screen, which can display more monitoring information, and the current monitoring information display interface can still be retained after the substation is powered off, which is convenient for underground maintenance and viewing, and improves the practicality of this solution.
