Description
Technical Field
The invention relates to a control system of a mining area crushing station and a control method of the mining area crushing station.
Background
Mining trucks need to transport material to a crushing station after it has been loaded during operations in a mine, the crushing station being one of the important destinations in the mine transport is currently mainly processing and executing information by staff or control equipment of the crushing station, whereas background control centers are usually only used for displaying information, which is not actually used for processing the received information.
In addition, the crushing station typically instructs the mining truck to perform a dump or wait job via a signal light. In this regard, in the case of an unmanned mining truck, the unmanned mining truck senses and detects the signal lamp of the crushing station through the camera carried by the unmanned mining truck, and if the unmanned mining truck is in a state such as a rainy day or a backlight, the camera of the unmanned mining truck is shielded and cannot accurately identify the signal lamp, so that the unmanned mining truck is influenced to timely make effective decisions.
Since the crushing process of the material in the crushing station requires time, it is often necessary to limit the travel speed of the mining truck in the crushing station. Here, conventional limiting speeds are typically obtained by mining trucks through map semantic information, and are typically fixed due to the complex map updating and non-real time. However, when the running road surface condition in the crushing station is poor (which may be affected by weather or for special reasons, for example), it is necessary to update the restricted running speed in the crushing station in time and send it to the mining truck, thereby avoiding accidents in the crushing station.
Disclosure of Invention

Mining trucks are required to transport material to a crushing station after loading of the material in the mine is completed. The control system of the mine crushing station according to the invention comprises an information acquisition device 1 and a control device 2. The information acquisition device 1 and the control device 2 are arranged in or near the crushing station. The information acquisition device 1 is used for detecting various parameters, preferably status parameters, of the crushing station, such as the number of mining trucks to be unloaded in the crushing station and their travelling speed in the crushing station, the road surface travelling conditions of the crushing station, the current running state of the crusher in the crushing station, the current crushing speed or amount of crushing of the crusher, the running failure of the crushing station (including, for example, a failure of the crusher or a failure of the mining truck being unloaded, etc.), etc.
The information acquisition device 1 may for example comprise one or more different sensors by means of which the above-mentioned various parameters of the crushing station are detected. In addition, the information acquisition device 1 comprises, for example, a global positioning system GPS by means of which the crushing station can be positioned, for example, the crushing station is equipped with a global navigation satellite system real-time differential positioning RTK. Alternatively, the position of the crushing station is located by a handheld RTK.
The information collecting device 1 is connected in a communication manner with the control device 2, and the information collecting device 1 transmits the collected various parameters and the position of the crushing station to the control device 2. The control device 2 is connected in communication with the background control center 3, and after receiving these parameters and the position of the crushing station, the control device 2 sends them to the background control center 3.
The background control center 3 includes, for example, a processor. The background control center 3 can automatically or manually set the operating state of the crushing station, which includes, for example, the crushing amount per hour or per day of the crushing station, how many mining trucks can be unloaded, and the like. The background control center 3 can obtain control instructions such as limited running speed of the mining truck in the crushing station, allowable unloading state of the unloading point and the like based on the variables and the received parameters. Wherein the discharge conditions allowed by the discharge point may comprise, for example, allowing discharge and prohibiting discharge. The background control center 3 can send out control commands, such as a limited travel speed of the mining truck in the crushing station, an allowable discharge state of the discharge point, etc., to the control device 2 of the crushing station for controlling the operating state in the crushing station.
The control system also has an execution device 4, and the control device 2 controls the execution device 4 to perform corresponding actions after receiving a control instruction of the background control center 3. For example, the execution device 4 may control the crushing speed of the crusher in accordance with the crushing amount per hour or per day of the crushing station provided by the background control center 3 or allow or prohibit the unloading of the mining truck in accordance with the control instructions of the background control center 3.
Preferably, the background control center 3 also has a function of remotely controlling the start and stop of the crushing station. For example, when the crushing station equipment fails and cannot be unloaded normally, when the positioning information sent by the crushing station deviates seriously (i.e. the positioning system may be disturbed), or when the crushing station is stagnated and the vehicle waiting for unloading is too many, the background control center 3 can analyze and judge, by means of its powerful processing unit, if necessary by personnel intervention, whether to control the stopping of the crushing station and/or make corresponding decisions, such as stopping the continuous unloading work of the following vehicles, stopping all work and making confirmation of the positioning system, scheduling part of the vehicles to travel away to the crushing station elsewhere, etc. For example, the background control center 3 can remotely control the crushing station to stop when receiving the crushing station failure information, and remotely control the crushing station to start again after the crushing station has eliminated the failure.
It is also conceivable here for the information acquisition device 1 to be connected in a communicative manner to the background control center 3, so that the information acquisition device 1 can send the acquired information, for example the above-mentioned parameters and the position of the crushing station, directly to the background control center 3 instead of via the control device 2.
In the present invention, mining trucks include unmanned mining trucks (also simply referred to as unmanned mining trucks) and manned mining trucks. The control device 2 of the background control center 3 and/or the crushing station is/are here connected in a communication manner with the mining truck. For example, a vehicle wireless communication V2X is mounted on the mining truck, which by means of V2X can receive from the background control center 3 and/or the control device 2 of the crushing station the limited travel speed of the mining truck in the crushing station, the permissible discharge state of the discharge point, etc., for vehicle control decisions. Of course, other communication schemes are possible, such as a 4G/5G/WiFi communication scheme.
If a mining truck is being driven, the limited travel speed in the crushing station, the permissible discharge state of the discharge point, etc. can also be displayed for the driver on a display device provided on the mining truck in real time, so that the driver can determine a driving decision from the above information.
In addition, the mining truck may receive the position of the crushing station from the background control center 3 and/or the control device 2 of the crushing station and/or the information acquisition device 1 by means of V2X.
The mining truck in the present invention is preferably an unmanned mining truck, and the crushing station in the present invention is preferably an unmanned crushing station. The present invention is not limited to unmanned mining trucks and unmanned crushing stations and may be applied to manned mining trucks and manned crushing stations.
Preferably, the crushing station is additionally provided with a signal lamp, which can be provided in a plurality of different colours to indicate different operating conditions. For example, the signal lights may be set to red and green, with the red signal light indicating prohibition or stop of discharge and the green signal light indicating normal discharge. Of course, other signal light arrangements are possible, as long as the travel state and/or the discharge state of the crushing station can be clearly indicated. In this case, a traffic light sensing device may be additionally installed for the unmanned mining truck in order to additionally recognize the operating state of the crushing station in order to reliably ensure safe and smooth operation. Whereas for a mining truck that is manned, the driving decision may be determined simply by the driver's visual recognition of the signal lights.
Additionally, the crushing station also provides an emergency stop button which can be operated by authorized personnel in the event of a malfunction or safety hazard, for example by entering a password or using a security key to trigger the emergency stop button. For example, in the event of a breakdown of the crusher of the crushing station or of a mining truck that is discharging, the emergency stop button can be triggered by authorized personnel to stop the crushing station in order to ensure personnel safety. The emergency stop button may be triggered, for example, when the crusher is damaged or when the crusher is stuck. Such an emergency stop button can ensure the safety of the crushing station, in particular in the event of a communication failure.
The control method of the mine crushing station is described below with reference to the information flow diagram in fig. 1. The control method comprises the following steps:
a detection step in which the state parameters of the crushing station are detected by the information acquisition device 1 and sent to the control device 2 of the crushing station in a communicative manner; and
and a control step, in which the control device 2 sends the received state parameters to a background control center 3 in a communication manner, and the background control center 3 obtains control instructions for the crushing station based on the received state parameters and sends the control instructions to the control device 2 so as to control the crushing station based on the control instructions.
The detecting step further comprises locating the crushing station to obtain the position of the crushing station.
In the control step, the background control center 3 can remotely control the stop and start of the crushing station.
After the control step, the control device 2 transmits control commands, in particular the limited travel speed of the mining truck in the crushing station and the permissible discharge state of the discharge point, in a communicating manner to the mining truck in the vicinity of the crushing station.
After the control step, the control device 2 controls the execution device 4 to perform a corresponding action based on the received control instruction.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Various modifications, additions, or substitutions can be made to the described embodiments by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
