Description

Technical Field

[0001] The invention relates to a method for quickly replacing a local electric control system of a coal mining machine and an Internet-based electric control system of a coal mining machine. Background Art

[0002] Due to the different conditions of coal seams and coal quality at the coal mining working face, different coal mines have different requirements for production capacity, safety, production, etc., different coal mining-related supporting equipment, various models of coal mining machines and large functional differences between them, the electrical control system of the coal mining machine generally provides different functional versions for different models. When the coal mining machine leaves the factory, different versions of the electrical control system will be installed according to demand to facilitate the normal production of different models of coal mining machines under different industrial control conditions.

[0003] When a shearer's industrial control conditions or production requirements undergo significant changes, the shearer's electronic control system must be replaced with a newer, adapted version. This highly specialized task is primarily performed by electrical engineers from the shearer manufacturer. This involves updating the system's functional configurations on-site, a tedious and error-prone process. Furthermore, engineers must travel from the manufacturer to the mine, significantly increasing both time and expense. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for replacing a coal mining machine electrical control system and an Internet-based coal mining machine electrical control system, which can quickly replace the coal mining machine electrical control system safely and efficiently.

[0005] The main technical solutions of the present invention are:

[0006] A method for replacing an electrical control system of a coal mining machine comprises the following steps:

[0007] Step 1: Generate a new electronic control system configuration file through a remote update device;

[0008] Step 2: Power on the coal mining machine;

[0009] Step 3: The remote update device establishes a connection with the local original electric control system of the coal mining machine via the Internet;

[0010] Step 4: The remote update device sends the new electric control system configuration file to the local original electric control system of the coal mining machine;

[0011] Step 5: The coal mining machine is powered on again and enters the electric control system update working mode, and updates the local original electric control system according to the new electric control system configuration file.

[0012] The specific process of step 1 is: setting model parameters and configuring functional modules for the new electronic control system through the remote update device, and generating a complete and encrypted configuration file of the new electronic control system.

[0013] The specific process of step 3 is: selecting the machine number of the corresponding coal mining machine through the remote updating device, and establishing a connection between the remote updating device and the local original electric control system of the corresponding coal mining machine according to the machine number.

[0014] The coal mining machine can be powered on by one of the following methods: pressing the start button on the coal mining machine, sending a signal to the power supply equipment upstream of the coal mining machine through the signal line to start the power supply; directly opening the corresponding power supply circuit of the power supply equipment upstream of the coal mining machine; connecting the control circuit of the power supply equipment upstream of the coal mining machine to the control device in the network through the communication interface, and remotely controlling the control circuit to start the power supply through the control device; establishing a communication connection between the control port of the power supply equipment upstream of the coal mining machine and the remote update device, and remotely starting the power supply with the remote update device.

[0015] The updating process in step 5 is as follows: the local original electric control system of the coal mining machine reads the new electric control system configuration file, selects the corresponding program package according to the machine model parameters in the new electric control system configuration file, forms a new main control program and executes the new main control program, and completes the update of the electric control system after combining the functional modules for the new electric control system according to the functional module configuration information in the new electric control system configuration file. The new electric control system enters normal operating state.

[0016] An Internet-based coal mining machine electronic control system includes a local electronic control system installed on the coal mining machine and a remote update device for setting and configuring the model parameters and functional modules of the local electronic control system. The local electronic control system is provided with an Internet interface module for interacting with the remote update device. The local electronic control system obtains new model parameter settings and functional module configuration information from the remote update device through the Internet interface module.

[0017] The local electronic control system includes multiple functional modules. In addition to the Internet interface module, the functional modules also include basic functional modules, multi-model adaptation modules and other optional functional modules. The basic functional modules are used to complete the basic functional control related to coal mining production, such as starting and stopping the coal mining machine motor, traction walking, drum rotation, and rocker arm lifting. The multi-model adaptation module has built-in program packages of multiple main control programs, and different program packages correspond to different model parameter combinations.

[0018] The machine parameters may include single drum / double drum, single frequency converter / double frequency converter, single cutting motor per rocker arm / double cutting motors per rocker arm, single pump / double pump, cutting motor rated current, traction motor rated current, pump motor rated current, coal mining machine model, voltage level, maximum coal cutting speed, maximum dispatching speed, minimum traction starting speed, drum radius, maximum rocker arm mining height, minimum rocker arm mining height, machine body length, working face length and support width.

[0019] The other optional functional modules include a chute remote control module, a memory cutting module, an inertial navigation positioning module, a mining height measurement and control module, a rocker arm monitoring module and a fuselage monitoring module. The chute remote control module is used to complete the interactive management work of remotely controlling the coal mining machine in the chute or on the ground, the memory cutting module is used to complete the control processing work of the memory cutting function, the inertial navigation positioning module is used to complete the control processing work of the inertial navigation positioning function, the mining height measurement and control module is used to complete the control processing work of the mining height measurement and control function, the rocker arm monitoring module is used to complete the control processing work of the rocker arm monitoring function, and the fuselage monitoring module is used to complete the control processing work of the fuselage monitoring function.

[0020] The other optional functional modules are all functional modules whose enabled and disabled states can be controlled by switches.

[0021] The beneficial effects of the present invention are:

[0022] Since the local electronic control system of the coal mining machine is pre-installed with multiple program packages, necessary and multiple optional functional modules, different program packages correspond to different machine parameter combinations, and different optional functional modules correspond to different functional requirements. Through the electronic control system replacement method of the present invention, it is only necessary to transmit an electronic control system configuration file with a very small amount of information through the Internet to freely switch between different coal mining machine models or different functional modules, which greatly shortens the replacement time of the electronic control system from the original hours to the current seconds, realizing efficient switching of the coal mining machine electronic control system and greatly improving the switching success rate.

[0023] Also, because the coal mining machine's local electronic control system is pre-installed with multiple program packages, necessary and optional modules, the amount of information that needs to be transmitted on the network when the electronic control system is replaced is very small, and none of the core control programs are involved, thus greatly improving the safety of the electronic control system replacement operation.

[0024] Since the local electronic control system is equipped with an Internet interface module, and the Internet interface module is connected to the remote update device, the coal mining machine's original factory engineers can remotely replace the coal mining machine's electronic control system by performing corresponding operations on the remote update device, greatly reducing time costs and economic expenses.

[0028] like Figure 1 As shown, the present invention discloses a method for replacing the electric control system of a coal mining machine (which may be referred to as the electric control system replacement method for short), comprising the following steps:

[0029] Step 1: Generate a new electronic control system configuration file through a remote update device;

[0030] Step 2: Power on the coal mining machine;

[0031] Step 3: The remote update device establishes a connection with the local original electric control system of the coal mining machine via the Internet;

[0032] Step 4: The remote update device sends the new electric control system configuration file to the local original electric control system of the coal mining machine;

[0033] Step 5: The coal mining machine is powered on again and enters the electric control system update working mode, and updates the local original electric control system according to the new electric control system configuration file.

[0034] There is no requirement for the order in which steps 1 and 2 must be performed.

[0035] The specific process of step 1 is: the remote update device provides a human-machine interface for the coal mining machine original factory engineer to configure the new (i.e., replaced) local electronic control system on the remote update device, including setting the machine model parameters and configuring various functional modules. The so-called configuration of various functional modules refers to determining which functional modules to enable and which functional modules to disable. The remote update device generates a complete and encrypted new electronic control system configuration file based on the set machine model parameters and the configured functional modules.

[0036] The specific process of step 3 is: the original factory engineer selects the machine number of the corresponding coal mining machine on the remote update device, and establishes a connection between the remote update device and the local original electric control system of the corresponding coal mining machine according to the machine number.

[0037] The method of powering on (including re-powering on) the coal mining machine can adopt one of the following methods: press the start button on the coal mining machine, and send a signal to the power supply equipment upstream of the coal mining machine (referring to the combination switch or magnetic starter) through the signal line to start the power supply; directly open the corresponding power supply circuit of the power supply equipment upstream of the coal mining machine; connect the control circuit of the power supply equipment upstream of the coal mining machine to the control device in the network through the communication interface, and remotely control the control circuit to start the power supply through the control device; establish a communication connection between the control port of the power supply equipment upstream of the coal mining machine and the remote update device, and use the remote update device to remotely start the power supply.

[0038] The update process in step 5 can be as follows: the local original electronic control system of the coal mining machine reads the new electronic control system configuration file, selects the corresponding program package according to the machine model parameters in the new electronic control system configuration file, forms a new main control program and executes the new main control program, and completes the update of the electronic control system after combining the functional modules for the new electronic control system according to the functional module configuration information in the new electronic control system configuration file, and the new electronic control system enters normal operation state.

[0039] The electric control system of the coal mining machine includes an Internet interface module, a basic function module, a multi-model adaptation module and all other optional function modules. The Internet interface module is used to communicate with the remote update device and is an interface module for receiving new electric control system configuration files. The basic function module is used to implement basic function control related to coal mining machine production. The multi-model adaptation module has built-in program packages corresponding to a variety of main control programs (main programs of the electric control system) and a variety of model parameters. Different program packages correspond to different model parameter combinations. By executing program packages corresponding to different model parameter combinations, the multi-model adaptation module participates in the functional control of other functional modules, thereby realizing the adaptation of the electric control system to different coal mining machine models. All other optional function modules are mainly used to complete the related control processing work of some additional measurement and control functions.

[0040] The updated shearer electronic control system also includes the Internet interface module, basic function module, multi-machine adaptation module, and all other optional function modules. The difference between the modules and the pre-update electronic control system is that the enabled and disabled states of all other optional function modules are different, which are determined by the function module configuration information in the new electronic control system configuration file.

[0041] like Figure 2As shown, the present invention also discloses an Internet-based coal mining machine electronic control system (which may be referred to as the electronic control system for short), which is an electronic control system based on the design concept of the above-mentioned coal mining machine electronic control system replacement method, including a local electronic control system installed on the coal mining machine and a remote update device for setting and configuring the machine parameters and functional modules of the local electronic control system. The local electronic control system is provided with an Internet interface module for interacting with the remote update device, and the local electronic control system obtains new machine parameter setting information and functional module configuration information from the remote update device through the Internet interface module.

[0042] The local electric control system includes a plurality of functional modules. In addition to the Internet interface module, the functional modules also include a basic functional module, a multi-model adaptation module and other optional functional modules. The basic functional module is used to complete the basic functional control related to coal mining production, such as the start and stop of the coal mining machine motor, traction walking, drum rotation, and rocker arm lifting. The multi-model adaptation module has built-in program packages corresponding to multiple main control programs (the main program of the electric control system) and a variety of machine model parameters. Different program packages correspond to different machine model parameter combinations. The multi-model adaptation module is used to perform functional control on various functional modules applicable to different coal mining machine models according to various machine model parameter combinations. If the enabled and executed program package changes, the corresponding electric control system will change. Compared with other optional functional modules, the Internet interface module, the basic functional module and the multi-model adaptation module are essential functional modules.

[0043] The machine model parameters may include single drum / double drum, single frequency converter / double frequency converter, single cutting motor per rocker arm / double cutting motors per rocker arm, single pump / double pump, cutting motor rated current, traction motor rated current, pump motor rated current, coal mining machine model, voltage level, maximum coal cutting speed, maximum dispatching speed, minimum traction starting speed, drum radius, maximum rocker arm cutting height, minimum rocker arm cutting height, machine body length, working face length, and support width. The machine model parameters to be used by the replaced local electronic control system are selected by the original coal mining machine manufacturer's engineer on the remote update device. The relevant selection information is sent to the local electronic control system of the coal mining machine before replacement via the Internet interface module, specifically to the multi-machine model adaptation module of the local electronic control system before replacement, so as to serve as the basis for the multi-machine model adaptation module to update the selection of each machine model parameter.

[0044] The other optional functional modules include a chute remote control module, a memory cutting module, an inertial navigation positioning module, a mining height measurement and control module, a rocker arm monitoring module and a fuselage monitoring module. The chute remote control module is used to complete the interactive management work of remotely controlling the coal mining machine in the chute or on the ground, the memory cutting module is used to complete the control processing work of the memory cutting function, the inertial navigation positioning module is used to complete the control processing work of the inertial navigation positioning function, the mining height measurement and control module is used to complete the control processing work of the mining height measurement and control function, the rocker arm monitoring module is used to complete the control processing work of the rocker arm monitoring function, and the fuselage monitoring module is used to complete the control processing work of the fuselage monitoring function.

[0045] The chute remote control module, memory cutting module, inertial positioning module, mining height measurement and control module, rocker arm monitoring module, and fuselage monitoring module are all functional modules whose activation and deactivation states can be controlled by switches. Changing the activation and deactivation combinations of other optional functional modules will also change the corresponding electronic control system.

[0046] like Figure 3 As shown, the remote update device may include a control module and a storage module, a display module, an input module, and an internet communication module connected to the control module bus. The remote update program is stored in the storage module. When operated via the remote update device, the control module invokes the remote update program and displays a human-computer interaction interface via the display module. The coal mining machine's original factory engineer sets machine parameters and configures functional modules via the input module. The remote update program encrypts the received machine parameter information and functional module configuration information to generate a complete new electronic control system configuration file. The internet communication module then sends the new electronic control system configuration file to the coal mining machine's local original electronic control system.

[0047] The remote update program may include user authentication login, machine parameter setting, coal mining machine function module configuration, electric control system configuration file generation, and remote transmission sections. During operation, the original engineer of the coal mining machine first logs in after identity authentication to enter the remote update program, and respectively performs machine parameter setting and coal mining machine function module configuration through the machine parameter setting and coal mining machine function module configuration sections. The machine parameters can be directly entered or selected from existing parameters. The function module can be configured by setting the switches of various other optional function modules. After completion, the electric control system configuration file generation section is entered to perform the electric control system configuration file generation operation. The electric control system configuration file generation section generates the electric control system configuration file using encryption technology based on the user input information picked up in the machine parameter setting section and the coal mining machine function module configuration section. Then the remote transmission section is entered, which establishes a remote communication connection with the electric control system of the target coal mining machine based on the machine number of the target coal mining machine input or selected by the user, and sends the electric control system configuration file to the target coal mining machine.

[0048] By utilizing remote communication technology, the operations of setting machine parameters and configuring functional modules, which were originally performed on-site at the coal mining machine, have been transferred to the remote end. This has not only greatly improved the efficiency and accuracy of the electronic control system update, but also ensured technical safety and significantly reduced time and economic costs.
