[0028] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0029] like Figure 1 As shown, an embodiment of the present disclosure proposes a control device, comprising: a working power supply 1, a first controller 2, a second controller 3, a first power line 4 and a second power line 5; wherein, the power supply end of the working power supply 1 is respectively connected to the first end of the first power line 4 and the first end of the second power line 5, and the second end of the first power line 4 is connected to the power supply end of the first controller 2, the second end of the second power line 5 is connected to the power supply end of the second controller 3, the second end of the first power line 4 is connected to the communication end of the first controller 2, the second end of the second power line 5 is connected to the communication end of the second controller 3, and the pulse locking signal is transmitted between the first controller 2 and the second controller 3 via the first power line 4 and the second power line 5.

[0030] It can be understood that since the power supply end of the working power supply 1 is respectively connected to the first end of the first power line 4 and the first end of the second power line 5, and the second end of the first power line 4 is connected to the power supply end of the first controller 2, and the second end of the second power line 5 is connected to the power supply end of the second controller 3, the working power supply 1 can supply power to the first controller 2 and the second controller 3, thereby ensuring the stable operation of the first controller 2 and the second controller 3, and then being able to meet the control requirements when the control device is applied to the comprehensive mining system.

[0031] At the same time, since the second end of the first power line 4 is connected to the communication end of the first controller 2, and the second end of the second power line 5 is connected to the communication end of the second controller 3, the pulse locking signal can be transmitted between the first controller 2 and the second controller 3 through the first power line 4 and the second power line 5, thereby realizing the locking between the first controller 2 and the second controller 3.

[0032] Therefore, when an emergency occurs, the interlock between the first controller 2 and the second controller 3 can be used to stop the operation of the equipment in time, thereby avoiding accidents such as equipment damage, casualties, etc. caused by the continued operation of the equipment. At the same time, the first controller 2 and the second controller 3 realize the transmission of pulse interlock signals through the first power line 4 and the second power line 5 used for power supply, thereby avoiding direct communication between the first controller 2 and the second controller 3 while realizing the interlock, and further avoiding the mutual interference problem between the first controller 2 and the second controller 3, so that the control device can ensure the safe and stable operation of the comprehensive mining system when applied to the comprehensive mining system.

[0033] It should be noted that the working power supply 1 is used to power the first controller 2 and the second controller 3, and is also used for the relay transmission of the pulse locking signal. The specific type of the working power supply 1 can be set according to actual needs and is not limited to this. For example, the working power supply 1 can output 12V DC power. Among them, the power supply end of the working power supply 1 can be connected to other external power supply devices.

[0034] The first controller 2 is used for automatic control. When the first controller 2 is used in the comprehensive mining system, the first controller 2 can be used to control the belt self-moving machine tail 12, the transfer machine, etc. The specific type of the first controller 2 can be set according to actual needs and is not limited. Among them, the first controller 2 can send a pulse locking signal according to an external instruction, and can also output a control command according to the received pulse locking signal.

[0035] The second controller 3 is used for automatic control. When the second controller 3 is used in the comprehensive mining system, the second controller 3 can be used to control the machine head hydraulic support 13, etc. The specific type of the second controller 3 can be set according to actual needs and is not limited to this. Among them, the second controller 3 can send a pulse locking signal according to an external instruction, and can also output a control command according to the received pulse locking signal.

[0036] The pulse blocking signal in the first controller 2 and the pulse blocking signal in the second controller 3 are the same, and the first controller 2 and the second controller 3 are in the same operating frequency.

[0037] If the communication end of the first controller 2 is directly connected to the communication end of the second controller 3, when the first controller 2 fails, the second controller 3 is likely to malfunction due to signal changes at the communication end of the first controller 2. Similarly, when the second controller 3 fails, the first controller 2 is also likely to malfunction due to signal changes at the communication end of the second controller 3.

[0038] In the present embodiment, since only the power supply line is used to transmit the pulse locking signal between the first controller 2 and the second controller 3, the first controller 2 and the second controller 3 cannot interfere with each other while achieving locking, thereby ensuring the stable and safe operation of the control device. Moreover, the installation of other communication lines 9 between the first controller 2 and the second controller 3 is avoided, thereby effectively reducing the cost of the control device.

[0039] The first power line 4 is used to transmit power and a pulse locking signal between the working power supply 1 and the first controller 2. The specific type of the first power line 4 can be set according to actual needs and is not limited to this.

[0040] The second power line 5 is used to transmit power and a pulse locking signal between the working power supply 1 and the second controller 3. The specific type of the first power line 4 can be set according to actual needs and is not limited to this.

[0041] like Figure 2 As shown, in some embodiments, the control device further includes: a first capacitor unit 6, the first capacitor unit 6 is connected in series between the second end of the first power line 4 and the communication end of the first controller 2, and the first capacitor unit 6 is used to transmit the pulse locking signal.

[0042] It can be understood that since the first capacitor unit 6 is connected in series between the second end of the first power line 4 and the communication end of the first controller 2, and the first capacitor unit 6 has the characteristic of passing AC and blocking DC, the first capacitor unit 6 can reliably transmit the pulse locking signal while isolating the first power line 4 and the communication end of the first controller 2, thereby reducing the impact of the power in the first power line 4 on the communication of the first controller 2, and further ensuring the safe and stable operation of the first controller 2.

[0043] It should be noted that the specific type of the first capacitor unit 6 can be set according to actual needs and is not limited to this.

[0044] like Figure 2 As shown, in some embodiments, the first power line 4 includes: a first positive cable 401 and a first negative cable 402; the first capacitor unit 6 includes: a first capacitor C1 and a second capacitor C2. The first end of the first capacitor C1 is connected to the first positive cable 401, and the second end of the first capacitor C1 is connected to the first communication end of the first controller 2, the first end of the second capacitor C2 is connected to the first negative cable 402, and the second end of the second capacitor C2 is connected to the second communication end of the first controller 2.

[0045] It can be understood that since the first end of the first capacitor C1 is connected to the first positive cable 401, and the second end of the first capacitor C1 is connected to the first communication end of the first controller 2, the first capacitor C1 can play the role of passing AC and blocking DC between the first positive cable 401 and the first communication end of the first controller 2; since the first end of the second capacitor C2 is connected to the first negative cable 402, and the second end of the second capacitor C2 is connected to the second communication end of the first controller 2, the second capacitor C2 can play the role of passing AC and blocking DC between the first negative cable 402 and the second communication end of the first controller 2.

[0046] Therefore, through the cooperation of the first capacitor C1 and the second capacitor C2, the first controller 2 and the second controller 3 can reliably transmit the pulse locking signal by using the first positive cable 401 and the first negative cable 402, and can also isolate the first positive cable 401 and the first communication end of the first controller 2 and the first negative cable 402 and the second communication end of the first controller 2, thereby reducing the impact of the electricity in the first positive cable 401 and the first negative cable 402 on the communication of the first controller 2, thereby ensuring the safe and stable operation of the first controller 2.

[0047] It should be noted that the first positive cable 401 is used for power transmission between the positive pole of the working power supply 1 and the positive pole of the power supply end of the first controller 2, as well as the transmission of pulse locking signals between the first controller 2 and the second controller 3. The specific type of the first positive cable 401 can be set according to actual needs and is not limited to this.

[0048] The first negative pole cable 402 is used for power transmission between the negative pole of the working power supply 1 and the negative pole of the power supply end of the first controller 2, and for transmission of pulse locking signals between the first controller 2 and the second controller 3. The specific type of the first negative pole cable 402 can be set according to actual needs and is not limited to this.

[0049] For example, the first positive cable 401 and the first negative cable 402 may be two wire cores in one power supply cable.

[0050] The first capacitor C1 is used in series connection between the first positive cable 401 and the first communication end of the first controller 2 . The specific capacitance value of the first capacitor C1 can be set according to actual needs and is not limited thereto.

[0051] The second capacitor C2 is used for connecting the first negative cable 402 and the second communication end of the first controller 2 in series. The specific capacitance value of the second capacitor C2 can be set according to actual needs and is not limited thereto.

[0052] like Figure 2 As shown, in some embodiments, the control device further includes: a second capacitor unit 7, the second capacitor unit 7 is connected in series between the second end of the second power line 5 and the communication end of the second controller 3, and the second capacitor unit 7 is used to transmit the pulse locking signal.

[0053] It can be understood that since the second capacitor unit 7 is connected in series between the second end of the second power line 5 and the communication end of the second controller 3, and the second capacitor unit 7 has the characteristic of passing AC and blocking DC, the second capacitor unit 7 can reliably transmit the pulse locking signal while isolating the second power line 5 and the communication end of the second controller 3, thereby reducing the impact of the power in the second power line 5 on the communication of the second controller 3, and further ensuring the safe and stable operation of the second controller 3.

[0054] It should be noted that the specific type of the second capacitor unit 7 can be set according to actual needs and is not limited to this.

[0055] like Figure 2 As shown, in some embodiments, the second power line 5 includes: a second positive cable 501 and a second negative cable 502; the second capacitor unit 7 includes: a third capacitor C3 and a fourth capacitor C4. The first end of the third capacitor C3 is connected to the second positive cable 501, and the second end of the third capacitor C3 is connected to the first communication end of the second controller 3, the first end of the fourth capacitor C4 is connected to the second negative cable 502, and the second end of the fourth capacitor C4 is connected to the second communication end of the second controller 3.

[0056] It can be understood that since the first end of the third capacitor C3 is connected to the second positive cable 501, and the second end of the third capacitor C3 is connected to the first communication end of the second controller 3, the third capacitor C3 can play the role of passing AC and blocking DC between the second positive cable 501 and the first communication end of the second controller 3; since the first end of the fourth capacitor C4 is connected to the second negative cable 502, and the second end of the fourth capacitor C4 is connected to the second communication end of the second controller 3, the fourth capacitor C4 can play the role of passing AC and blocking DC between the second negative cable 502 and the second communication end of the second controller 3.

[0057] Therefore, through the cooperation of the third capacitor C3 and the fourth capacitor C4, the first controller 2 and the second controller 3 can reliably transmit the pulse locking signal by using the second positive cable 501 and the second negative cable 502, and can also isolate the first communication end of the second positive cable 501 and the second communication end of the second controller 3 and the second negative cable 502 and the second controller 3, thereby reducing the impact of the electricity in the second positive cable 501 and the second negative cable 502 on the communication of the second controller 3, thereby ensuring the safe and stable operation of the second controller 3.

[0058] It should be noted that the second positive cable 501 is used for power transmission between the positive pole of the working power supply 1 and the positive pole of the second controller 3, as well as the transmission of pulse locking signals between the first controller 2 and the second controller 3. The specific type of the second positive cable 501 can be set according to actual needs and is not limited to this.

[0059] The second negative cable 502 is used for power transmission between the negative pole of the working power supply 1 and the negative pole of the power supply end of the second controller 3, and for transmission of pulse locking signals between the first controller 2 and the second controller 3. The specific type of the second negative cable 502 can be set according to actual needs and is not limited to this.

[0060] For example, the second positive cable 501 and the second negative cable 502 may be two wire cores in one power supply cable.

[0061] The third capacitor C3 is used for connecting the second positive cable 501 in series with the first communication end of the second controller 3. The specific capacitance value of the third capacitor C3 can be set according to actual needs and is not limited thereto.

[0062] The fourth capacitor C4 is used for the series connection between the second negative cable 502 and the second communication end of the second controller 3. The specific capacitance value of the fourth capacitor C4 can be set according to actual needs and is not limited thereto.

[0063] like Figure 1 As shown, in some embodiments, the control device also includes: at least one third controller 8 and at least one communication line 9, the first end of the communication line 9 is connected to the communication end of the second controller 3, and the second end of the communication line 9 is connected to the communication end of the third controller 8.

[0064] It can be understood that since the first end of the communication line 9 is connected to the communication end of the second controller 3, and the second end of the communication line 9 is connected to the communication end of the third controller 8, the second controller 3 and the third controller 8 can communicate through the communication line 9, thereby meeting the collaborative control requirements.

[0065] At the same time, since the first controller 2 and the second controller 3 only use the first power line 4 and the second power line 5 to transmit the pulse locking signal, the first controller 2 and the second controller 3 cannot interfere with each other while achieving locking, thereby ensuring reliable and stable coordinated action between the second controller 3 and the third controller 8.

[0066] It should be noted that the third controller 8 is used for automatic control. When the third controller 8 is applied to the comprehensive mining system, the third controller 8 can be used to control the machine head hydraulic support 13, etc. The specific type of the third controller 8 can be set according to actual needs and is not limited to this. Among them, the third controller 8 can be the same as the second controller 3.

[0067] like Figure 1 As shown, in some embodiments, the control device further includes: a first button 10, the first button 10 is connected to the input end of the first controller 2, and the first controller 2 is used to output a pulse locking signal to the second controller 3 according to the instruction of the first button 10.

[0068] It is understandable that, since the first button 10 is connected to the input end of the first controller 2, the first controller 2 can receive the instruction of the first button 10, and output a pulse locking signal to the second controller 3 according to the instruction of the first button 10, thereby meeting the control requirements.

[0069] It should be noted that the first button 10 is used by the operator to input instructions to the first controller 2 so as to utilize the first controller 2 to implement the emergency stop action of the second controller 3. The specific type of the first button 10 can be set according to actual needs and is not limited to this. For example, the first button 10 can be an emergency stop button.

[0070] like Figure 1 As shown, in some embodiments, the control device further includes: a second button 11, the second button 11 is connected to the input end of the second controller 3, and the second controller 3 is used to output a pulse locking signal to the first controller 2 according to the instruction of the second button 11.

[0071] It is understandable that, since the second button 11 is connected to the input end of the second controller 3, the second controller 3 can receive the instruction of the second button 11, and output a pulse locking signal to the first controller 2 according to the instruction of the second button 11, thereby meeting the control requirements.

[0072] It should be noted that the second button 11 is used by the operator to input instructions to the second controller 3 so as to use the second controller 3 to implement the emergency stop action of the first controller 2. The specific type of the second button 11 can be set according to actual needs and is not limited to this. For example, the second button 11 can be an emergency stop button.

[0073] like Figure 1 As shown, the embodiment of the present disclosure also proposes a comprehensive mining system, including: a control device as the embodiment of the present disclosure.

[0074] It can be understood that since the power supply end of the working power supply 1 is respectively connected to the first end of the first power line 4 and the first end of the second power line 5, and the second end of the first power line 4 is connected to the power supply end of the first controller 2, and the second end of the second power line 5 is connected to the power supply end of the second controller 3, the working power supply 1 can supply power to the first controller 2 and the second controller 3, thereby ensuring the stable operation of the first controller 2 and the second controller 3, and thus being able to meet the control requirements.

[0075] At the same time, since the second end of the first power line 4 is connected to the communication end of the first controller 2, and the second end of the second power line 5 is connected to the communication end of the second controller 3, the pulse locking signal can be transmitted between the first controller 2 and the second controller 3 through the first power line 4 and the second power line 5, thereby realizing the locking between the first controller 2 and the second controller 3.

[0076] Therefore, when an emergency occurs, the interlock between the first controller 2 and the second controller 3 can be used to stop the operation of the equipment in time, thereby avoiding accidents such as equipment damage, casualties, etc. caused by the continued operation of the equipment. At the same time, the first controller 2 and the second controller 3 realize the transmission of pulse interlock signals through the first power line 4 and the second power line 5 for power supply, thereby avoiding direct communication between the first controller 2 and the second controller 3 while realizing the interlock, thereby avoiding mutual interference between the first controller 2 and the second controller 3, and ensuring the safe and stable operation of the comprehensive mining system.

[0077] It should be noted that the fully mechanized coal mining system is a comprehensive mechanized coal mining system, which includes a coal mining machine, a scraper conveyor, a head hydraulic support 13, a transfer machine, a belt self-moving tail 12, etc. The first controller 2 and the second controller 3 in the control device can be respectively arranged on two devices at a relatively long distance.

[0078] Among them, emergencies in the comprehensive mining system include the transfer machine being scratched and the monorail crane being deformed.

[0079] like Figure 1 As shown, in some embodiments, the fully mechanized mining system further includes: a belt self-moving tail 12 and a head hydraulic support 13, the belt self-moving tail 12 is arranged away from the fully mechanized mining working face, and the input end of the belt self-moving tail 12 is connected to the output end of the first controller 2 in the control device, and the head hydraulic support 13 is arranged close to the fully mechanized mining working face, and the input end of the head hydraulic support 13 is connected to the output end of the second controller 3 in the control device. Among them, the first controller 2 is used to stop the action of the belt self-moving tail 12 according to the pulse locking signal sent by the second controller 3, and / or the second controller 3 is used to stop the action of the head hydraulic support 13 according to the pulse locking signal sent by the first controller 2.

[0080] It can be understood that since the input end of the belt self-moving tail 12 is connected to the output end of the first controller 2, the first controller 2 can control the movement of the belt self-moving tail 12; since the input end of the head hydraulic support 13 is connected to the output end of the second controller 3, the second controller 3 can control the movement of the head hydraulic support 13.

[0081] Therefore, when an emergency occurs, the first controller 2 can stop the action of the belt self-moving tail 12 according to the pulse locking signal sent by the second controller 3, thereby avoiding accidents such as equipment damage and casualties caused by the continued action of the belt self-moving tail 12.

[0082] When an emergency occurs, the second controller 3 can stop the operation of the head hydraulic support 13 according to the pulse locking signal sent by the first controller 2, thereby avoiding accidents such as equipment damage and casualties caused by the continued operation of the head hydraulic support 13.

[0083] It should be noted that during the advancement of the comprehensive mining working face, the belt self-moving machine tail 12, the machine head hydraulic support 13, etc. all need to move with it. Therefore, through the cooperation of the first controller 2 and the second controller 3, accidents can be effectively avoided.

[0084] For example, in a certain comprehensive mining system, an accident caused by unclear signal transmission occurs approximately once every nine months. Each accident affects production time by an average of 8 hours, causing direct economic losses of 150,000 yuan. Based on an hourly coal output of 1,600 tons and a current coal price of 640 yuan per ton, the indirect economic losses caused by a single accident amount to 10.24 million yuan. The control device of this embodiment can recover losses of 15.58 million yuan each year.

In addition, in the description of the present disclosure, unless otherwise specified, "plurality" means two or more.
