Through the integration of system configuration and architecture, end-to-end data interaction from the inertial navigation system server to the airborne inertial navigation device of the mining machine at the underground working face is realized, meeting the application needs of mine inertial navigation system communication delay, channel bandwidth, and communication stability.

[0004] When some existing coal mine underground airborne inertial navigation 5G wireless communication systems are in use, due to the unstable signal of the communication equipment when working, it is necessary to adjust the power to improve the overall signal strength, but the overall energy consumption will also increase accordingly, so the overall energy consumption needs to be monitored. Secondly, there is information leakage in the process of data transmission of communication equipment, and the lack of security will lead to the leakage of personal information. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an airborne inertial navigation 5G wireless communication system for underground coal mines, which solves the problem that energy consumption changes corresponding to power changes and cannot be well monitored, and secondly, lacks security in the process of data transmission.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A coal mine underground airborne inertial navigation 5G wireless communication system, comprising:

[0007] A real-time acquisition unit is used to acquire basic information of a target object, wherein the target object includes: 5G communication equipment, and the basic information includes: working time, remaining power and power, and transmit the basic information of the target object to an energy consumption monitoring unit;

[0008] The energy consumption monitoring unit is used to obtain the basic information of the target object to be transmitted and analyze it. By analyzing the power consumption under different power, and then analyzing the working time under different power, the corresponding energy consumption monitoring information is generated, and the energy consumption monitoring information is transmitted to the energy consumption early warning unit;

[0009] The energy consumption warning unit is used to obtain the transmitted energy consumption monitoring information and analyze it, respectively calculate and analyze the working time under the power GLi and the adjusted power GLt to obtain energy consumption warning information, and transmit the energy consumption warning information to the communication information output unit;

[0010] The data transmission analysis unit is used to obtain the transmission data and encrypt the transmission data according to the capacity of the transmission data and the signal strength of the communication device in different time periods, and at the same time generate transmission encryption information and transmit it to the communication information output unit.

[0011] As a further solution of the present invention: the specific manner in which the energy consumption monitoring unit generates energy consumption monitoring information is as follows:

[0012] S1: Get the power and record it as GLi, and i=1, 2, ..., n, then get the working time Ti and power consumption HDi corresponding to the power GLi, then calculate the average power consumption corresponding to the power GLi and record it as Hpi. In this process, the power consumption is first calculated. The power consumption is calculated by subtracting the remaining power from the total power of the device, and the total power of the device is 100%. At the same time, GLi is expressed as the average power consumption under different power working states, and different powers are expressed as the power that the 5G communication equipment can work normally when working;

[0013] S2: Then, the adjusted power is obtained and recorded as GLt, and the working time Tt and power consumption HDt corresponding to the adjusted power GLt are obtained. Similarly, the average power consumption corresponding to the adjusted power GLt is calculated and recorded as Hpt. The adjusted power is expressed as the maximum power of the communication equipment during operation. Since there is signal shielding in the coal mine, the power of the communication equipment needs to be adjusted to enhance the overall communication signal.

[0014] S3: Finally, the remaining power values ​​corresponding to the communication equipment under power GLi and adjusted power GLt are calculated and recorded as SCi and SCt. The specific calculation method is: obtain the total power Dz of the communication equipment, and then obtain the power consumption HDi and HDt respectively, calculate the difference between the total power Dz and the power consumption and record it as the remaining power SCi and SCt, and generate energy consumption monitoring information. Here, the remaining power is calculated for a single power during the working process, that is, the remaining power of the communication equipment after working time T.

[0015] As a further solution of the present invention: the specific manner in which the energy consumption warning unit generates energy consumption warning information is as follows:

[0016] P1: Get the working time Ti and power consumption HDi of the power GLi, and the working time Tt and power consumption HDt of the adjusted power GLt, then substitute Dz, HDi and HDt into the formula SC=Dz-HDi-HDt to calculate the remaining power of the target object, recorded as SC;

[0017] P2: Then substitute the remaining power SC and the average power consumption Hpi corresponding to the power GLi into the formula The working time T1 corresponding to the power GLi is calculated, where a is the power self-loss factor, and a=0.351, YS is the power warning preset value, and YS is the proportional value. It should be noted here that the working time T1 is expressed as the time required to consume the remaining power SC to the preset value YS under a single power GLi working state, and the specific proportional value of YS is set by the operator;

[0018] P3: Then substitute the remaining power SC and the average power consumption Hpt corresponding to the power GLt into the formula The working time T2 corresponding to the power GLt is calculated. The T2 calculated here represents the time required to reach the warning power under the single power GLt working state;

[0019] P4: Get the working time Ti of power GLi, substitute the remaining power SC, working time Ti, average power consumption Hpt and average power consumption Hpi into the formula The working time T3 is calculated, and T3 is expressed as the maximum working time of adjusting the power GLt after the power GLi works for Ti time, and Ti×Hpi is expressed as the power consumed by the power GLi working for Ti time. Specifically, the initial working power is GLi by default, and the overall power of the device needs to be adjusted due to the change in signal strength after the power GLi works for Ti time, and then the time to reach the warning power is calculated based on the adjusted power.

[0020] As a further solution of the present invention: the specific manner in which the data transmission analysis unit generates the transmission encryption information is as follows:

[0021] A1: Obtain the capacity of the transmitted data and record it as RL, then obtain the signal strength of the communication device within the time period TS and record it as QDj, where j=1, 2, ..., n, and obtain the maximum and minimum values ​​of the communication device signal strength, which are recorded as QDmax and QDmin respectively; It should be noted here that the time period TS represents the time unit in seconds, j represents the strength of the communication device per second, and the specific time period TS value is set by the operator.

[0022] A2: Then, the numerical property of the capacity RL of the transmitted data is analyzed and judged, and the capacity RL is judged to be an odd number or an even number. At the same time, the transmission encryption is performed for different cases where the capacity RL is an odd number and the capacity RL is an even number. The specific encryption method is as follows:

[0023] A21: When the capacity RL is an odd number, the maximum value QDmax of the signal strength of the communication device in the previous time period TS is obtained, and the capacity RL is divided by the maximum value QDmax, and Q transmission data packets are generated, where Q = the value of QDmax, and then the average of the maximum and minimum values ​​of the signal strength in the previous time period TS is obtained and recorded as QDp, and a virtual data packet with the same size as the QDp value is generated, and then the generated virtual data packets are interspersed in the Q transmission data packets according to an odd number, and new reorganized transmission data is generated at the same time; specifically, firstly, the parity of the capacity of the transmission data is judged, and then the corresponding encryption information is generated according to the signal strength within the time period, and the time period is the time period before the current time period.

[0024] A22: When the capacity RL is an even number, the median value of the signal strength of the communication device in the previous time period TS is obtained and recorded as QDz. At the same time, the capacity RL is divided into two equal parts, and then virtual data with the same capacity as the QDz value is generated, and the virtual data is interspersed between the two equal parts of the transmission data packets, and new recombined transmission data is generated. Specifically, it is assumed here that the number of signal strength values ​​in the time period TS exceeds two. Specifically, the encryption method in the first time period TS is an ordinary encryption method, and is an encryption method in the prior art. The encryption of the transmission data in this application is performed starting from the second time period, and different virtual data packets are generated in different time periods.

[0025] As a further solution of the present invention: a communication information output unit is used to obtain the transmitted energy consumption warning information and transmission encryption information, and display it to the operator through a display device; a real-time acquisition unit is used to obtain the transmission data transmitted by the target object and the basic data of the transmission data, wherein the basic data includes: time period and capacity, and transmit the transmission data and its basic data to the data analysis unit; the real-time acquisition unit is electrically connected to the energy consumption monitoring unit and the data transmission analysis unit in a unidirectional manner, and the energy consumption monitoring unit is electrically connected to the energy consumption warning unit in a unidirectional manner, and the data transmission analysis unit is electrically connected to the communication information output unit in a unidirectional manner.

[0026] Beneficial Effects

[0027] The present invention provides a coal mine underground airborne inertial navigation 5G wireless communication system. Compared with the prior art, it has the following beneficial effects:

[0028] The present invention analyzes the working time of communication equipment under different power levels and further analyzes the situation in which power adjustment is required later, thereby monitoring the overall energy consumption of communication equipment and timely giving early warning to the communication equipment to avoid the impact on subsequent communication due to insufficient energy consumption. Secondly, for the data transmitted by the communication equipment, the signal strength in different periods is analyzed, and the transmitted data is encrypted according to the analysis result, thereby improving the security of the overall transmission of the transmitted data.

The specific method of generating the energy consumption monitoring information is as follows:

[0035] S1: Get the power and record it as GLi, and i=1, 2, ..., n, then get the working time Ti and power consumption HDi corresponding to the power GLi, then calculate the average power consumption corresponding to the power GLi and record it as Hpi. In this process, the power consumption is first calculated. The power consumption is calculated by subtracting the remaining power from the total power of the device, and the total power of the device is 100%. At the same time, GLi is expressed as the average power consumption under different power working states, and different powers are expressed as the power that the 5G communication equipment can work normally when working;

[0036] S2: Then, the adjusted power is obtained and recorded as GLt, and the working time Tt and power consumption HDt corresponding to the adjusted power GLt are obtained. Similarly, the average power consumption corresponding to the adjusted power GLt is calculated and recorded as Hpt. The adjusted power is expressed as the maximum power of the communication equipment during operation. Since there is signal shielding in the coal mine, the power of the communication equipment needs to be adjusted to enhance the overall communication signal.

[0037] S3: Finally, the remaining power values ​​corresponding to the communication equipment under power GLi and adjusted power GLt are calculated and recorded as SCi and SCt. The specific calculation method is: obtain the total power Dz of the communication equipment, and then obtain the power consumption HDi and HDt respectively, calculate the difference between the total power Dz and the power consumption and record it as the remaining power SCi and SCt, and generate energy consumption monitoring information. Here, the remaining power is calculated for a single power during the working process, that is, the remaining power of the communication equipment after working time T.

[0038] The energy consumption warning unit is used to obtain the transmitted energy consumption monitoring information and analyze it, respectively calculate and analyze the working time under the power GLi and the adjusted power GLt to obtain energy consumption warning information, and transmit the energy consumption warning information to the communication information output unit at the same time. The specific method of generating the energy consumption warning information is as follows:

[0039] P1: Get the working time Ti and power consumption HDi of the power GLi, and the working time Tt and power consumption HDt of the adjusted power GLt, then substitute Dz, HDi and HDt into the formula SC=Dz-HDi-HDt to calculate the remaining power of the target object, recorded as SC;

[0040] P2: Then substitute the remaining power SC and the average power consumption Hpi corresponding to the power GLi into the formula The working time T1 corresponding to the power GLi is calculated, where a is the power self-loss factor, and a=0.351, YS is the power warning preset value, and YS is the proportional value. It should be noted here that the working time T1 is expressed as the time required to consume the remaining power SC to the preset value YS under a single power GLi working state, and the specific proportional value of YS is set by the operator;

[0041] P3: Then substitute the remaining power SC and the average power consumption Hpt corresponding to the power GLt into the formula The working time T2 corresponding to the power GLt is calculated. The T2 calculated here represents the time required to reach the warning power under the single power GLt working state;

[0042] P4: Get the working time Ti of power GLi, substitute the remaining power SC, working time Ti, average power consumption Hpt and average power consumption Hpi into the formula The working time T3 is calculated, and T3 is expressed as the maximum working time of adjusting the power GLt after the power GLi works for Ti time, and Ti×Hpi is expressed as the power consumed by the power GLi working for Ti time. Specifically, the initial working power is GLi by default, and the overall power of the device needs to be adjusted due to the change in signal strength after the power GLi works for Ti time, and then the time to reach the warning power is calculated based on the adjusted power.

[0043] The communication information output unit is used to obtain the transmitted energy consumption warning information and display it to the operator through the display device.

[0044] Embodiment 2, as embodiment 2 of the present invention, differs from embodiment 1 in that the real-time acquisition unit acquires the transmission data of the target object and transmits it to the data analysis unit, which analyzes and processes the data.

[0045] The data transmission analysis unit is used to obtain the transmission data, and perform transmission encryption processing on the transmission data according to the capacity of the transmission data, and at the same time generate transmission encryption information and transmit it to the communication information output unit. The specific method of generating the transmission encryption information is as follows:

[0046] A1: Obtain the capacity of the transmitted data and record it as RL, then obtain the signal strength of the communication device within the time period TS and record it as QDj, where j=1, 2, ..., n, and obtain the maximum and minimum values ​​of the communication device signal strength, which are recorded as QDmax and QDmin respectively; It should be noted here that the time period TS represents the time unit in seconds, j represents the strength of the communication device per second, and the specific time period TS value is set by the operator.

[0047] A2: Then, the numerical property of the capacity RL of the transmitted data is analyzed and judged, and the capacity RL is judged to be an odd number or an even number. At the same time, the transmission encryption is performed for different cases where the capacity RL is an odd number and the capacity RL is an even number. The specific processing method is as follows:

[0048] A21: When the capacity RL is an odd number, the maximum value QDmax of the signal strength of the communication device in the previous time period TS is obtained, and the capacity RL is divided by the maximum value QDmax, and Q transmission data packets are generated, where Q = the value of QDmax, and then the average of the maximum and minimum values ​​of the signal strength in the previous time period TS is obtained and recorded as QDp, and a virtual data packet with the same size as the QDp value is generated, and then the generated virtual data packets are interspersed in the Q transmission data packets according to an odd number, and new reorganized transmission data is generated at the same time; specifically, firstly, the parity of the capacity of the transmission data is judged, and then the corresponding encryption information is generated according to the signal strength within the time period, and the time period is the time period before the current time period.

[0049] A22: When the capacity RL is an even number, the median value of the signal strength of the communication device in the previous time period TS is obtained and recorded as QDz. At the same time, the capacity RL is divided into two equal parts, and then virtual data with the same capacity as the QDz value is generated, and the virtual data is interspersed between the two equal parts of the transmission data packets, and new recombined transmission data is generated. Specifically, it is assumed here that the number of signal strength values ​​in the time period TS exceeds two. Specifically, the encryption method in the first time period TS is an ordinary encryption method, and is an encryption method in the prior art. The encryption of the transmission data in this application is performed starting from the second time period, and different virtual data packets are generated in different time periods.

[0050] The communication information output unit is used to obtain the transmitted encrypted information and display it to the operator through the display device.
