[0028] Figure 1 It is a schematic diagram of the overall structure of a control cabinet of the present utility model. Detailed implementation manners

[0029] The following further elaborates the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of description, only parts related to the relevant utility model are shown in the drawings.

[0030] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will detail the present application with reference to the drawings and embodiments.

[0031] AsFigure 1 As shown in Figure 1 , a control cabinet proposed in the first embodiment of the present utility model can remotely and safely control oil wells and pumping unit equipment. The control cabinet includes a cabinet body 1, and a controller 2 is installed inside the cabinet body 1. The controller 2 is connected to a switch device, a starting device 3, an in-cabinet video device 4, an out-of-cabinet video device 5, an in-cabinet alarm 6, an out-of-cabinet alarm 7, and a motor 8.

[0032] The switch device includes a remote switching main switch 9 and at least one single-device remote switching switch 10 connected to the remote switching main switch 9. Each single-device remote switching switch 10 is connected to a starting device 3. The starting device 3 is connected to the motor 8, the motor 8 is connected to the controller 2, and the remote switching main switch 9 is connected to a power supply 11.

[0033] In the present utility model, the starting device 3 includes a frequency converter 15 and an AC contactor 16.

[0034] Ports of the frequency converter 15 are respectively connected to the controller 2, the single-device remote switching switch 10, and the AC contactor 16. Ports of the AC contactor 16 are respectively connected to the motor 8 and the controller 2.

[0035] In the present utility model, the controller 2 is further connected to a monitoring terminal 22, and the monitoring terminal 22 is used to control the startup of the in-cabinet video device 4 and the out-of-cabinet video device 5.

[0036] Among them, the controller 2 is connected to an in-cabinet lighting device 14. The in-cabinet lighting device 14 is fixed inside the cabinet body 1, and the in-cabinet lighting device 14 is used to assist the in-cabinet video device 4 in obtaining in-cabinet video data.

[0037] A sensor 17 is installed outside the cabinet body 1. The sensor 17 is connected to the controller 2, and the sensor 17 is used to detect equipment operation data.

[0038] Among them, the in-cabinet alarm 6, the in-cabinet video device 4, the starting device 3, a local or remote conversion switch 18, a start switch 19, and a stop switch 20 are installed inside the cabinet body 1.

[0039] Among them, the power supply 11 is a three-phase power supply.

[0040] In this embodiment, the power supply 2 is sent to the upper port of the remote switching main switch 3 in the cabinet body 1. At this time, if it is necessary to start the motor 8, the operator opens the video images of the in-cabinet video device 4 and the out-of-cabinet video device 5 on the monitoring terminal 22 to observe whether there are any potential hazards in the two video images. With the assistance of the in-cabinet lighting device 14, the in-cabinet video device 4 clearly transmits the in-cabinet video image back, and the out-of-cabinet video device 5 can clearly transmit the on-site video image back with the help of the video auxiliary light source. If the operator does not open these two images, the monitoring terminal 22 cannot perform any further operations. The operator can judge whether the inside of the cabinet body 1 and the equipment site are safe by means of the visual function and the video device image automatic capture technology. If there are any risk factors inside the cabinet body 1 or at the site, the in-cabinet alarm 6 and the out-of-cabinet alarm 7 will give an alarm, and the start button on the monitoring terminal 22 will be invalid.

[0041] If there are no potential hazards inside the cabinet body 1 or at the site, the operator presses the start button on the monitoring terminal 22. The controller 2 issues a closing command for the remote switching main switch 9 in the starting device 3. After the closing is completed, the controller 2 issues a closing command for the remote switching switch 10 of a single device. At this time, the controller 2 establishes communication with the frequency converter 15. If the frequency converter 15 does not report a fault, at this time, the controller 2 issues a command for the AC contactor 16 to close. After the AC contactor 16 closes and the frequency converter does not report a fault, the controller 2 issues a disk pump command. The AC contactor 16 controls the motor 8 to operate according to the preset disk pump frequency and time. At this time, the controller 2 monitors the operating parameters of the frequency converter 15 in real time. The in-cabinet video device 4 and the out-of-cabinet video device 5 use the video device image automatic capture technology to monitor the operating state of the equipment in real time. At the same time, the operator monitors the operating state of the equipment in real time through the monitoring terminal 22. If the operating parameters of the frequency converter 15 do not show any abnormalities at this time and the video device does not detect any potential hazards, the frequency converter 15 enters the normal operating state. The operating frequency of the frequency converter 15 can be controlled by the monitoring terminal 22 according to the process requirements. If it is necessary to stop the operation of the frequency converter 15, it can be controlled by the monitoring terminal 22 or automatically controlled by the on-site sensor 17.

[0042] In the present utility model, through the viewing of the video image by the duty personnel and the analysis of the video image by the controller, these two conditions must be met simultaneously. Normally, online remote power supply cut-off and power-on can be carried out, so that the safety of the pump power supply can be effectively guaranteed through civil air defense and technical defense. When power is supplied, a voice prompt "The pump is about to start" will be given on-site. The application of the disk pump program can discover the problems existing in the pump in the first time and ensure the safety of the equipment operation. The in-cabinet video device and the on-site video device monitor the operating state of the equipment in real time. When a problem is found, an alarm and shutdown will be carried out in the first time.

[0043] As Figure 1 shown, a control cabinet proposed in the second embodiment of the present utility model, on the basis of the first embodiment, the remote switching main switch 9 is connected to at least one remote switching switch 10 of a single device, and its structure is:

[0044] The remote switching main switch 9 is connected to the electric energy metering module 12, the electric energy metering module 12 is connected to the voltage monitoring module 13 and the controller 2, the voltage monitoring module 13 is connected to the controller 2, and the line between the electric energy metering module 12 and the voltage monitoring module 13 is connected to the remote switching switch 10 of a single device.

[0045] In this embodiment, if there is no hazard source in the cabinet 1 or on site, the operator presses the start button on the monitoring terminal 22, and the controller 2 issues a closing command for the remote switching main switch 9 in the starting device 3. After the closing is completed, the voltage monitoring module 13 monitors the voltage in real time. If the voltage is abnormal, the controller issues an alarm command, and an alarm screen appears on the monitoring terminal 22, and the controller 2 stops issuing any commands. If the voltage is normal, the controller 2 issues a closing command for the remote switching switch 10 of a single device. At this time, the controller 2 establishes communication with the frequency converter 15;

[0046] The electric energy metering module 12 transmits the equipment operation energy consumption to the monitoring terminal 22 in real time through the controller 2.

[0047] As Figure 1 As shown, a control cabinet proposed in the third embodiment of the present invention, on the basis of the first embodiment or the second embodiment, the controller 2 is further connected to a local or remote changeover switch 18, a start switch 19 and a stop switch 20, and the local or remote changeover switch 18 is used to switch between local control and remote control;

[0048] When in local control, the start and stop of the motor 8 are controlled by the start switch 19 and the stop switch 20.

[0049] When using the remote function, the power supply 11 is sent to the upper port of the remote switching main switch 9 in the cabinet 1, and the local or remote changeover switch 18 is turned to remote. At this time, if it is necessary to start the motor 8, the operator opens the video images of the in-cabinet video device 4 and the out-of-cabinet video device 5 on the monitoring terminal 22.

[0050] Turn the local or remote transfer switch 18 to the local position. At this time, the monitoring terminal 22 starts, and the stop button therein becomes ineffective. If it is necessary to start the motor 8, the operator manually closes the remote switching main switch 9 and the remote switching switch 10 for a single device, presses the start switch 19, and the controller 2 issues a command for the AC contactor 16 to close. If the controller 2 does not detect any abnormalities in the voltage of the power supply 11 and the frequency converter 15 at this time, the controller 2 issues a disk pump command, and the frequency converter 15 controls the motor 8 to operate according to the preset disk pump frequency and time. At this time, the controller 2 monitors the operating parameters of the frequency converter 15 in real time. If no abnormalities are found, the frequency converter 15 enters the normal operating state. The operating frequency of the frequency converter 15 can be controlled by the on-site frequency adjustment knob according to the process requirements or can be automatically controlled by the on-site sensor 17. If it is necessary to stop the device from running, press the stop switch 20, and the controller 2 controls the frequency converter 15 to stop running.

[0051] As Figure 1 shown, a control cabinet proposed in the fourth embodiment of the present invention, based on the first embodiment or the second embodiment or the third embodiment, the controller 2 is connected to the voice prompt module 21, and the controller 2 controls the motor 8 according to the voice data issued by the voice prompt module 21.

[0052] In this embodiment, if the frequency converter 15 does not report a fault, at this time the controller 2 issues a command for the AC contactor 16 to close. After the AC contactor 16 closes and the frequency converter 15 does not report a fault, the voice prompt module 21 issues a voice prompt. After the voice prompt reaches the set time, the controller 2 issues a disk pump command, and the voice prompt module 21 controls the motor 8 to operate according to the preset disk pump frequency and time.
