The analysis shows that the existing device for controlling the smelting furnace guides a hydraulic control system to a control cabinet, the smelting furnace is controlled by operating the control cabinet, the problem that keys on the cabinet often fail occurs, when one key fails, the working state of the smelting furnace stops at present, the whole smelting process cannot be continued, and great inconvenience is brought.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an apparatus for controlling a melting furnace according to an embodiment of the present invention includes: a signal transmitting unit 10, an operation unit 20, a signal receiving unit 30; the signal sending unit 10 sends out different electrical signals, the operating unit 20 receives the different electrical signals and sends corresponding instructions, and the signal receiving unit 30 receives the different instructions sent by the operating unit 20 to perform corresponding operations.
In this embodiment, the signals sent by the signal transmitting unit 10 include a start signal 11, a stop signal 12, a reset signal 13, and an action signal 14; the action signal may comprise a tip-over signal, a flip-over signal, a close-over signal. Specifically, the start signal 11 is a signal for controlling the smelting furnace so that the smelting furnace starts; the suspension signal 12 is a signal that controls the smelting furnace such that the smelting furnace is suspended; the reset signal 13 is a signal that controls the melting furnace such that the melting furnace is reset; other action signals for controlling the smelting furnace are also included, such as the tipping signal, which refers to a signal for controlling the body of the smelting furnace so that the body produces a tipping action; the flip signal refers to a signal of an action that a furnace cover of the smelting furnace needs to be opened in the smelting process of the smelting furnace; the cover closing signal refers to a signal that an action of closing the cover is required after opening the cover.
In this embodiment, the operating unit 20 receives the corresponding signal, and then converts the received signal into a corresponding command, where the correspondingly generated command includes a start command, a stop command, a reset command, and an action command, and the action command includes a tip-over command, a cover command, and a cover closing command. And then transmits the corresponding instruction.
In this embodiment, the signal receiving unit 30 receives the instruction transmitted by the operating unit 20, processes the received instruction, and controls the corresponding circuit after the operations such as processing and identification are performed, so that the smelting furnace performs the related operations.
In addition to the several operation signals mentioned in the above embodiments, other operation signals may be added according to the operation requirements of the melting furnace, or only part of the above operations and the control requirements for part of the operations may be added.
With continued reference to fig. 1, the operation unit 20 converts and transmits the corresponding signals through the command encoding circuit 21, the modulation circuit 22 and the transmission circuit 23.
Specifically, the instruction encoding circuit 21 is responsible for receiving the signal sent by the signal transmitting unit 10, encoding the signal, and generating a corresponding instruction encoding signal; for example, the instruction encoding circuit 21 receives a start signal transmitted by the signal transmitting unit 10, and the instruction encoding circuit correspondingly encodes the start signal to generate a start instruction encoding signal. The modulation circuit 22 receives the command encoding signal transmitted by the command encoding circuit 21, modulates the command encoding signal, and generates a corresponding command; for example, the modulation circuit 22 receives the start instruction encoding signal transmitted from the instruction encoding circuit 21, and the modulation circuit 22 modulates the start instruction encoding signal to generate a start instruction. The transmitting circuit 23 sends out the instruction transmitted by the modulating circuit 22; for example, the transmitting circuit 23 transmits the start instruction after receiving the start instruction generated after modulation by the modulating circuit 22. The above is the transmission process of the signal.
The above example is the process of transmitting the start signal 11, and the process from transmitting the stop signal 12, the reset signal 13, the action signal 14, and the like from the transmitting unit to transmitting is the same.
With continued reference to fig. 1, after the signal is transmitted, the signal receiving unit 30 receives and processes it.
Specifically, the signal receiving unit 30 receives signals and performs corresponding processing through the receiving circuit 31, the demodulation circuit 32, the instruction decoding circuit 33, and the driving circuit 34. The receiving circuit 31 receives the instruction transmitted by the transmitting circuit 23, and transmits the instruction to the demodulating circuit 32 after receiving the instruction; for example, when the operation unit transmits a start instruction, the receiving circuit 31 receives the start instruction transmitted by the transmitting circuit 23 and transmits the start instruction to the demodulating circuit 32. Subsequently, the modulation circuit 32 demodulates the instruction received by the receiving circuit 31 to demodulate a corresponding instruction encoding signal; for example, the start command received by the receiving circuit 31 is demodulated to obtain a start command encoded signal. The command encoding signal is decoded and then recognized, so that the command decoding circuit 33 decodes the modulated command encoding signal to transmit to the driving circuit 34; for example, the command decoding circuit 33 decodes the start command encoding signal and then transmits the decoded signal to the driving circuit 34. After the driving circuit 34 recognizes the instruction encoding signal decoded by the instruction decoding circuit, the corresponding circuit is driven to execute the corresponding operation; for example, the command encoding signal decoded by the decoding circuit 33 is a start command encoding signal, and the driving circuit 34 recognizes the start command encoding signal and then controls the corresponding execution circuit, so that the melting furnace completes the start operation.
The working method of the device comprises the following steps:
referring to fig. 2, first, as shown in step S1, different electrical signals are sent by the signal sending unit, where the different signals include a start signal, a stop signal, a reset signal, and an action signal, and in this embodiment, the action signal includes a flip signal, a close signal, and a tip signal. Then, as step S2, the operation unit receives the different electrical signals sent by the sending unit, and sends corresponding instructions according to the received different electrical signals; the operation unit converts different signals into different commands and transmits the different commands, wherein the corresponding different commands comprise a starting command, a stopping command, a resetting command and an action command, and in the embodiment, the action command comprises a flip command, a cover closing command and a tilting command. Finally, in step S3, the signal receiving unit receives the command transmitted by the operating unit, and performs corresponding processing after receiving the command.
Specifically, after receiving the signal sent by the signal sending unit, the operating unit codes the signal through the instruction coding circuit, and then generates a corresponding instruction coding signal; the instruction coding signal is modulated through a modulation circuit, and only the modulated signal can be transmitted, so that the instruction coding signal is modulated to form a corresponding instruction; and finally, transmitting the instruction through a transmitting circuit.
The signal receiving unit receives the instruction transmitted by the transmitting circuit through a receiving circuit; when the receiving circuit receives the instruction, the receiving circuit transmits the instruction to the demodulation circuit, the instruction is demodulated through the demodulation circuit, and a corresponding instruction coding signal is demodulated; decoding the command encoding signal through a command decoding circuit; and identifying the command coding signal decoded by the decoding circuit through a driving circuit, and then driving a corresponding circuit according to the command coding signal to enable the smelting furnace to complete corresponding operation.
The driving circuit drives the smelting furnace to execute corresponding actions through a hydraulic system, and the driving circuit drives the hydraulic system to work after identifying a corresponding instruction so as to control the smelting furnace.
For example, when the smelting furnace needs to be controlled to perform a tilting action, a tilting signal is sent through the signal sending unit firstly, and then the operation unit receives the tilting signal and converts the tilting signal into an instruction which can be sent out and emits the instruction; and finally, the signal receiving unit receives the tilting instruction transmitted by the operation unit, and corresponding operation is carried out after the processing and the identification of each circuit, so that the tilting control of the action of the smelting furnace is realized.
It should be understood that the above examples are for the purpose of performing a tilting action of the melting furnace, and if other actions are required, such as controlling the start, stop, reset, lid-turning, lid-closing or other actions of the melting furnace, the same way as the above examples is performed. The device for controlling the action of the smelting furnace provided by the embodiment is a wireless remote control device, and the smelting furnace can be controlled by the wireless remote control device and an original control cabinet, so that when the control cabinet is abnormal or fails, the smelting furnace can be controlled by the wireless remote control device, and the phenomenon that the smelting furnace is paralyzed and cannot work continuously can not occur.
Moreover, the original control cabinet is far away from the smelting furnace and is generally arranged 5 meters away from the smelting furnace, but in the working process of the smelting furnace, the original control cabinet is often required to be observed and correspondingly controlled in a short distance, the control cabinet is far away and cannot be controlled in real time generally, and particularly when an emergency situation occurs and corresponding measures are required to be implemented as soon as possible, the control cabinet cannot meet the requirements; the control distance of the wireless remote control equipment provided by the invention is not limited, and the wireless remote control equipment can control the smelting furnace even within half a meter of the smelting furnace, so that the operation condition in the smelting furnace can be observed more flexibly and controlled in real time.
