In the actual operation process of the drilling rig, when multiple devices such as the catwalk, the iron driller, and the second floor need to be operated simultaneously, multiple drillers need to cooperate to operate the devices. The traditional operation mode not only increases the labor cost, but also has low operation efficiency. SUMMARY

The controller is connected with the industrial computer through the switch. The controller is adapted to be electrically connected with the top drive system, the iron driller, the second floor and the catwalk through the switch.

[0005] The centralized control cabinet is provided with a power input module and a power conversion module.

[0028] By integrating the controller 110, the switch 120, the industrial computer 130 and the like in the centralized control cabinet, the controller 110 collects the running state data of each device through the switch 120, and transmits the collected data to the industrial computer 130 through the switch 120, and the industrial computer 130 displays the running state of the device in real time. The driller operates the controller 110 to give each device an operation instruction based on the data displayed by the industrial computer 130. The highly integrated design of the centralized control cabinet enables one person to complete the control operation of the top drive system 410, the iron roughneck 420, the catwalk 440 and the like, greatly improving the operation convenience and the comprehensive drilling operation efficiency. The system of the application adopts a centralized processing mode, and the controller 110 uniformly coordinates the operation of each device, avoiding inconsistent operation of multiple people and mutual interference between devices, and ensuring that each device can accurately cooperate according to the predetermined program. In addition, the integrated control design reduces the number of operating personnel and reduces labor costs.

[0029] As shown in FIGS. Figure 4 , Figure 5 The main body of the centralized control cabinet is in a hollow box structure, and the inner wall of the centralized control cabinet is fixedly installed with a clamping rail 101. The switch 120, the controller 110 and the socket 260 are all installed in the centralized control cabinet through the clamping rail 101. The switch 120 is arranged adjacent to the controller 110, and the socket 260 is located below the controller 110. The centralized control cabinet is provided with a cabinet door 102 which is hinged to the side wall of the centralized control cabinet. The industrial computer 130 is fixedly installed on the cabinet door 102, and when the cabinet door 102 is closed, the industrial computer 130 is located in the cavity of the centralized control cabinet. The output end of the controller 110 is connected with the X8 interface of the switch 120 through a network cable. The top drive system 410, the iron roughneck 420, the catwalk 440 and the like are respectively connected with the corresponding interfaces of the switch 120 through network cables. The controller 110 collects the running data of each device through the switch 120, and operates each device based on the collected running data of each device. Meanwhile, the interface of the industrial computer 130 is connected with the X5 interface of the switch 120 through a network cable. The controller 110 transmits the collected running data of each device to the industrial computer 130 through the switch 120. The industrial computer 130 can display the received running data and store the data at the same time.

[0030] Further, the controller 110 controls the running and stopping of the devices based on the collected running data between the top drive system 410, the iron roughneck 420, the catwalk 440 and the like. When the collected data exists interference, the controller 110 controls the top drive system 410, the iron roughneck 420, the catwalk 440 and the like to stop running. When the collected data does not exist interference, the controller 110 controls the top drive system 410, the iron roughneck 420, the catwalk 440 and the like to be put into use.

[0031] Specifically, such as Figure 3 As shown, when the controller 110 controls the top drive system 410, the drill rig 420, the second-floor platform 430, and the catwalk 440 to operate and collect data such as the operating status and location of each device; the collected data from the second-floor platform 430 is compared with the data from the top drive system 410, the drill rig 420, and the catwalk 440 respectively. When the data of any device interferes with the data of the second-floor platform 430, the controller 110 controls the second-floor platform 430 to stop operating, otherwise it continues to operate; the collected data from the catwalk 440 is compared with the data from the top drive system 410 and the drill rig 420 respectively. When the data of any device interferes with the data of the catwalk 440, the controller 110 controls the catwalk 440 to stop operating, otherwise it continues to operate; the collected data from the top drive system 410 and the drill rig 420 are compared. When the data of the two interfere with each other, the controller 110 controls the top drive system 410 and the drill rig 420 to stop operating, otherwise it continues to operate.

[0032] Preferably, the top drive system 410 adopts the existing technology model: DQ90Bs top drive drilling rig, the iron drill 420 adopts the existing technology model: SMR140z iron drill, the second platform 430 adopts the existing technology model: SY75C Sany Heavy Industry excavator, and the catwalk 440 adopts the existing technology model: HCW-90 automatic catwalk 440.

[0033] Furthermore, the controller 110, switch 120, industrial computer 130, top drive system 410, iron drill 420, second-floor platform 430, and catwalk 440 all use PROFINET communication for information data transmission; preferably, the switch 120 is the EDS-208A switch 120 used in the prior art.

[0034] In one possible implementation, the industrial computer 130 is an all-in-one machine with storage function. The industrial computer 130 will receive and store the data collected by the controller 110. By setting the data storage function, it provides data support for later equipment maintenance and performance optimization.

[0035] Furthermore, the industrial PC 130 adopts the existing PPC-3150-RE4BE / 500G industrial panel PC.

[0036] In one possible implementation, the controller 110 uses a CPU1513-1PN programmable logic controller.

[0037] In one possible implementation, the power conversion module includes: two switching power supplies 310; the two switching power supplies 310 are connected in parallel, and the input terminals of the two switching power supplies 310 are electrically connected to the first output terminal of the power input module.

[0038] It should be noted that, as shown in Figure 2 , Figure 4 , two switching power supplies 310 are installed in the control cabinet through the card 101, and the two switching power supplies 310 are arranged adjacent to each other on the side of the switch 120 away from the controller 110. The switching power supply 310 is suitable for converting the AC power of the power supply module into DC power and then delivering it to the controller 110 and the switch 120. The input end of the switching power supply 310 is electrically connected to the first output end of the power input module. The output end of the switching power supply 310 is electrically connected to the input end of the controller 110 and the input end of the switch 120. The switching power supply 310 converts the AC 220V voltage delivered by the power input module into DC 24V voltage to supply power to the controller 110 and the switch 120. When the switch is closed, the current can normally flow from the power input module to the power conversion module. The power conversion module converts the DC power into AC power to supply power to the controller 110 and the switch 120. The design of the two switching power supplies 310 in parallel adds the output power of the two switching power supplies 310, ensuring the power demand of the controller 110 and the switch 120, avoiding the failure of the controller 110 and the switch 120 due to insufficient power, and ensuring the stable operation of the equipment.

[0039] Further, the switching power supply 310 uses the existing 6EP3334-3SA00-0AY0 DC24V / 10A electrical element.

[0040] In one possible implementation, the power conversion module includes a unidirectional diode 320. The controller 110 and the switch 120 are electrically connected to the output ends of the two switches through the unidirectional diode 320.

[0041] It should be noted that, as shown in Figure 2 , Figure 4 , the unidirectional diode 320 is installed in the control cabinet through the card rail 101, and the unidirectional diode 320 is located on the side of the controller 110 away from the switch 120. The unidirectional diode 320 is suitable for preventing the two switching power supplies 310 from returning the power. The anode of the switch is electrically connected to the anode of the controller 110 and the switch 120 through the unidirectional diode 320. The cathode of the switch is electrically connected to the cathode of the controller 110 and the switch 120, respectively. When the switch is closed, the switching power supply 310 converts the DC voltage and supplies power to the controller 110 and the switch 120 through the unidirectional diode 320. When the switch is open, if there is a reverse current or other reasons that may cause a reverse current, due to the one-way conduction characteristic of the diode itself, the reverse current cannot pass through the diode and is blocked, avoiding the reverse current passing through the switching power supply 310 back to the power input module, ensuring that the power input module will not be affected by the reverse current.

[0042] In a possible implementation manner, the power input module comprises: a line circuit breaker 210 and a purification power supply 220; an output end of the line circuit breaker 210 is electrically connected to an input end of the purification power supply 220. It should be noted that, as shown in Figure 2 、 Figure 4 , the line circuit breaker 210 is installed in the centralized control cabinet through the card rail 101, and the line circuit breaker 210 is arranged adjacent to the socket 260; the purification power supply 220 is bolted and fixedly installed in the centralized control cabinet and located above the switch 120; the output end of the line circuit breaker 210 is electrically connected to the input end of the purification power supply 220; the first output end of the purification power supply 220 is electrically connected to the controller 110 and the switch 120 through the power conversion module; and the second output end of the purification power supply 220 is electrically connected to the industrial computer 130. When a short circuit occurs, the line circuit breaker 210 can quickly cut off the circuit to avoid damage to the power input module and subsequent equipment caused by the short circuit current; and the purification power supply 220 can filter the input alternating current to keep the output voltage within the voltage range required for normal operation of the equipment, thereby avoiding damage to the equipment caused by abnormal voltage.

[0043] In a possible implementation manner, the power input module further comprises a UPS power supply 230; and the UPS power supply 230 is arranged in parallel with the power input module.

[0044] It should be noted that, as shown in Figure 2 、 Figure 4 , the UPS power supply 230 is bolted and fixedly installed in the centralized control cabinet; and the output end of the power input module and the output end of the UPS power supply 230 are electrically connected to the input end of the DC / DC converter. When the power input module is in normal operation, the power input module provides power to the DC / DC converter, thereby providing power to the equipment in the centralized control cabinet; at this time, the UPS power supply 230 is in a standby state. When the power supply connected through the power input module fails, the DC / DC converter switches to the UPS power supply 230 to continuously provide power to the equipment in the centralized control cabinet, thereby ensuring that the integrated control system of the driller of the oil drilling rig does not stop running due to power interruption, achieving uninterrupted power supply. The system adopts a multiple redundant power supply design, reduces system failures caused by power supply problems, and improves the power supply reliability of the system.

[0045] Further, as shown in Figure 4 , a battery 231 is arranged in the centralized control cabinet and located below the UPS power supply 230; and the output end of the battery 231 is electrically connected to the input end of the UPS power supply 230. The UPS power supply 230 provides uninterrupted power to the equipment in the centralized control cabinet through the battery 231.

[0046] In a possible implementation manner, as shown in Figure 5As shown, the power indicator 240 is fixedly installed on the cabinet door 102 and located below the industrial computer 130. The power indicator 240 is electrically connected with the output end of the power conversion module, and is suitable for monitoring the power supply condition of the power conversion module. When the switching power supply 310 is closed, the power indicator 240 is in the energized state, at this time, the power indicator 240 is in the lighting state. Through the power supply state monitoring of the power indicator 240, the power supply abnormality can be found and handled in time.
