[0022] The technical solutions of the present application will be described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Referring to Figures 1-5 The present application provides a mine car automatic dispatching device in intelligent mine construction, which comprises a mine car dispatching station 1 used for dispatching mine cars and a mine car automatic dispatching mechanism. The mine car automatic dispatching mechanism comprises a central control unit, a mine car positioning unit, a wireless communication unit, a mine car state monitoring unit, an execution unit, a display unit and an alarm unit, wherein:

[0024] The central control unit adopts a high-performance industrial computer, and an advanced scheduling algorithm software is built-in. The central control unit is responsible for receiving data from the mine car positioning unit and the mine car state monitoring unit, analyzing and processing, and generating scheduling instructions according to the preset scheduling strategy. The mine car positioning unit obtains the position information of the mine car in real time, and transmits the position data to the central control unit through the wireless communication unit. The wireless communication unit includes a wireless communication transmitting module and a wireless communication receiving module. The number of wireless communication transmitting modules is set to multiple, and the multiple wireless communication transmitting modules are respectively installed and fixed on the corresponding mine cars and the turnout control device and the signal lamp control device. The positioning terminal, the turnout control device and the signal lamp control device are electrically connected with the wireless communication transmitting module. The wireless communication receiving module is installed and fixed in the mine car scheduling station 1, and is electrically connected with the central control unit. The wireless communication unit can use the existing 4G or 5G communication network to realize data transmission between the central control unit, the mine car positioning unit, the mine car state monitoring unit and the execution unit. The wireless communication unit using the 4G or 5G communication network can ensure the timeliness and stability of data transmission, ensure that the scheduling instructions can be accurately issued to the mine car, realize real-time control and dynamic adjustment of the whole mine car scheduling system. The central control unit and the alarm unit are installed and fixed in the mine car scheduling station 1, and the display unit is installed and fixed on the outside of the mine car scheduling station 1. The central control unit, the display unit and the alarm unit are electrically connected.

[0025] In the embodiment, the mine car positioning unit includes a positioning terminal and a positioning base station, and the number of the positioning terminal and the positioning base station is set to multiple. The multiple positioning terminals are respectively installed and fixed on the corresponding mine cars, and the multiple positioning base stations are arranged in the surrounding area of the mine and are uniformly distributed. The execution unit includes a turnout control device and a signal lamp control device installed on the mine car running track. The multiple positioning terminals are respectively installed on the corresponding mine cars, and cooperate with the multiple positioning base stations uniformly distributed in the surrounding area of the mine to realize real-time and accurate positioning of the position of each mine car. The central control unit can generate scheduling instructions according to the position information, and issue instructions to the turnout control device and the signal lamp control device through the wireless communication unit to realize switching of the turnout and display of the signal lamp, thereby realizing efficient planning and scheduling of the mine car running path, guiding the mine car to run according to the planned route, greatly improving the mine transportation efficiency, and reducing the waiting and congestion time of the mine car.

[0026] In this embodiment, it needs to be supplemented that the positioning terminal is a device integrating multiple hardware modules, mainly including satellite signal receiving antenna, signal processing chip and data transmission interface. The satellite signal receiving antenna is responsible for capturing positioning signals from satellites, and its design has high sensitivity, which can stably receive weak satellite signals in the complex terrain environment of the mine as much as possible. The signal processing chip processes the original signals obtained by the receiving antenna in a series of processes, including signal demodulation and data analysis, which converts satellite signals into understandable position data. The position data is transmitted to the central control unit through the wireless communication unit to ensure that the position information can be transmitted in time. The positioning base station is mainly composed of high-precision satellite signal receiving equipment, data processing unit and communication equipment. The satellite signal receiving equipment is similar to the antenna of the positioning terminal on the mine car, but has higher performance and accuracy to provide more accurate positioning reference. The data processing unit is responsible for complex operations on received satellite signals to generate high-precision positioning correction data. The communication equipment is used for data interaction with the positioning terminal and the central control unit, sends the positioning correction data to the positioning terminal, receives the position information fed back by the positioning terminal, and forwards it to the central control unit.

[0027] The principle of positioning the mine car is:

[0028] Satellite signal reception and measurement: The satellite signal receiving antennas of the positioning terminal and the positioning base station continuously receive signals from multiple satellites (such as 24 satellites in the GPS system and dozens of satellites in the Beidou system). These satellites constantly emit signals with time stamps and orbit information to the earth. The positioning terminal measures the time difference of different satellite signals, uses the principle of constant speed of light, and calculates the distance between itself and each satellite by combining the known orbit position of the satellite. For example, assuming that the positioning terminal receives signals from three satellites A, B and C, it can calculate the distances d1, d2 and d3 from satellites A, B and C by measuring the signal arrival time. According to the principle of triangular positioning, take three satellites as the spherical center and their respective distances as the radius to draw a sphere. The intersection of the three spheres is the position of the positioning terminal.

[0029] Differential positioning principle (improve accuracy): The positioning base station uses its high-precision satellite signal receiving equipment to accurately measure the deviation between its own position and the theoretical position, i.e. the differential correction value. The positioning base station sends these differential correction values to the positioning terminal on the mine car through the communication equipment. After receiving the differential correction values, the positioning terminal corrects the position data calculated by itself, thereby significantly improving the positioning accuracy. For example, if the position calculated by the positioning terminal itself has a certain deviation, by applying the differential correction value provided by the positioning base station, the position accuracy can be improved from the meter level of ordinary positioning to sub-meter level or even higher accuracy, meeting the demand for accurate positioning of mine cars in mines and ensuring accurate determination of the position of mine cars in complex transportation routes, providing reliable position basis for the central control unit to make reasonable scheduling plan.

[0030] Real-time data transmission: After obtaining and processing the position data, the positioning terminal transmits the position data to the central control unit in real time through the wireless communication unit using 4G or 5G wireless communication technology. At the same time, the positioning base station also sends the relevant data obtained by itself and the data exchanged with the positioning terminal to the central control unit through the wireless communication unit, so that the central control unit can obtain accurate position information of each mine car in real time, providing key data support for subsequent scheduling instruction generation.

[0031] In this embodiment, the mine car state monitoring unit includes a speed sensor, a load sensor, a vibration sensor, and a high-definition camera. The number of speed sensors, load sensors, vibration sensors, and high-definition cameras is set to multiple. Multiple speed sensors are respectively installed and fixed on corresponding mine cars. Multiple load sensors are respectively installed and fixed on corresponding mine cars. Multiple vibration sensors are respectively installed and fixed on corresponding mine cars. Multiple high-definition cameras are respectively installed and fixed on corresponding mine cars. The speed sensor, load sensor, vibration sensor, and high-definition camera are electrically connected with the wireless communication transmission module. The speed sensor feeds back the driving speed of the mine car in real time. The load sensor monitors the load of the mine car. The vibration sensor can sense abnormal vibration during vehicle driving. The high-definition camera can monitor the environment and loading state around the mine car in real time. These monitored data are transmitted to the central control unit through the wireless communication unit, so that the central control unit can make reasonable scheduling according to the actual state of the mine car and timely grasp the running condition of the mine car, ensuring transportation safety.

[0032] In this embodiment, the display unit is a liquid crystal display 2, which is fixedly embedded on the outer wall of the mine car dispatching station 1. The liquid crystal display 2 can intuitively present key information such as the position and running state of the mine car, facilitating observation by the staff. Through the setting of the alarm unit, when the mine car state monitoring unit detects abnormal conditions such as excessive speed, abnormal load, excessive vibration, etc., the central control unit will immediately trigger the alarm unit to display on the liquid crystal display 2, reminding the staff to handle it in time, effectively preventing safety accidents, ensuring the safety of mine operation. The control panel 3 is fixedly installed on the mine car dispatching station 1, and the control panel 3 is electrically connected with the central control unit. A plurality of control buttons are arranged on the control panel 3. By using the plurality of control buttons, a convenient operation mode is provided for the staff, and manual intervention and control of the dispatching system can be realized in time.

[0033] Through the above structure, the working principle of the mine car automatic dispatching device in the intelligent mine construction provided by the present application is as follows:

[0034] The positioning terminal installed on the mine car cooperates with the positioning base stations evenly distributed around the mine area. The positioning terminal continuously emits signals, and the positioning base stations receive the signals and calculate the real-time position information of the mine car through a specific algorithm. The position information is transmitted to the wireless communication receiving module in the mine car dispatching station 1 through the wireless communication transmitting module connected with the positioning terminal, and then transmitted to the central control unit.

[0035] By using the speed sensor, load sensor, vibration sensor and high-definition camera as the key part of the mine car state monitoring unit, the driving speed, load condition, running vibration and surrounding environment and loading state of the mine car are monitored in real time. The information obtained by each sensor and high-definition camera is also transmitted to the wireless communication receiving module through the wireless communication transmitting module connected therewith, and finally reaches the central control unit. For example, the speed sensor senses the speed of the mine car in real time, the load sensor monitors the load of the car, the vibration sensor captures abnormal vibration of the vehicle, and the high-definition camera transmits the surrounding picture of the mine car back to the central control unit, providing comprehensive mine car running state data for the central control unit.

[0036] Based on the received position and state information of the mine car, the central control unit combines the transportation task and real-time working condition of the mine to make comprehensive analysis and decision. When it is necessary to adjust the driving path of the mine car, the central control unit sends instructions to the turnout control device and the signal lamp control device through the wireless communication unit. The instructions are transmitted to the receiving end of the turnout control device and the signal lamp control device through the wireless communication transmitting module, so that the turnout control device changes the position of the turnout and the signal lamp control device switches the state of the signal lamp, guiding the mine car to drive according to the planned path, realizing efficient dispatching, and further greatly improving the transportation efficiency of the mine, reducing the waiting and congestion time of the mine car.

[0037] The central control unit transmits the processed mine car position, running state and other key information to the liquid crystal display 2 for intuitive display, which facilitates the staff to master the mine car scheduling situation in real time. Meanwhile, the control panel 3 on the mine car scheduling station 1 is connected with the central control unit, and the staff can input instructions to the central control unit through multiple control buttons on the control panel 3, so as to manually intervene in the scheduling system, such as urgently adjusting the running route of a mine car or suspending part of the transportation task.

[0038] When the central control unit receives abnormal information from the mine car state monitoring unit, such as vehicle speed exceeding the preset range, abnormal load, excessive vibration and the like, the alarm unit will be triggered immediately, and the alarm unit transmits the alarm signal to the liquid crystal display 2, so that the alarm indication can be displayed on the liquid crystal display 2, the alarm is sounded, and the staff is reminded to handle the abnormal situation in time, so as to ensure the safety of mine operation.
