Description

Technical Field

[0001] The invention belongs to the technical field of monitoring systems, and in particular relates to a remote control oil pumping unit safety protection method and device. Background Art

[0002] In order to promote high-quality and high-level development of oil and gas field exploitation, ensure the safe advancement of all production links, and improve the safety management mechanism, oil and gas field enterprises have gradually paid more attention to the safety hazards of beam pumping equipment. In recent years, various oil fields have taken inter-well pumping as the main direction of improving the efficiency of mechanical production. Pumping wells are automatically turned on and off for production, and the well site monitoring conditions are limited. Some operators see the pumping unit stop and approach the pumping unit to work. When the pumping unit suddenly starts, it has a serious impact on the personal safety of employees and the economic benefits of the enterprise.

[0003] At the same time, referring to Li Ming's article "Analysis and Countermeasures of Dangerous Point Sources of Beam Pumping Units", common dangerous point sources of beam pumping units include broken pumping unit base, cracked donkey head, brake failure, crank balance block rotation area danger, crank pin breakage danger, belt drive danger and other major dangerous point sources. According to the survey, the existing common guardrails of pumping units are 130cm from the ground and 86cm from the center of the crank. It is easy for people to enter the dangerous area from below. It does not meet the structural design criteria, that is, "the dangerous area should be indicated when the machine is moving, especially to prevent the human body from entering the dangerous area. The protective device should have the function of isolation to ensure the personal safety of the operator and the safety of the machine operation."

[0004] The article "Application Analysis of Pumping Unit Safety Protection Devices" identifies the problems existing in the application of pumping unit safety protection devices and proposes the next improvement direction. The proposed safety fence only plays an isolating role and does not provide necessary protection for the personal safety of operators when the oil well opening conditions are not met. Chinese patent number CN112664052B discloses a workstation automatic protection fence safety system, but the switch door of the system is an opaque door, which is not convenient for well site personnel outside the protection fence to observe the situation inside the protection fence, and there are certain safety hazards. In addition, only an alarm is installed on the switch door, and it is impossible to notify the remote monitoring personnel to observe the well site situation in time, make calls to stop or even stop the pumping unit, so the system is not suitable for oil field pumping unit well site conditions. Summary of the invention

DETAILED DESCRIPTION

[0068] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] A remote control oil pumping unit 1 safety protection method, such as Figure 1 As shown, the following steps are included:

[0070] S1: Build a safety protection device around the oil pump 1, specifically: S101: Build a guardrail 6 around the oil pump 1; S102: Open a switch door 2 on one side of the guardrail; S103: Install an electronic fingerprint lock 10 and a first camera 201 on the switch door 2; S104: Install an alarm and a monitor on the outside of the guardrail 6.

[0071] S2: Collecting personnel information data, establishing an identity data set, and entering it into the internal list in the security protection device, specifically: S201: Collecting information, including the name and fingerprint information of internal personnel; S202: Entering the collected information into the internal list of the electronic fingerprint lock 10.

[0072] S3a: When a single person enters the security protection device, the information data is entered. If the information data does not match the identity data set, it is determined to be a stranger, and the identity data of the stranger is marked, and the facial image is collected and entered into the observation list, and an alarm is sounded at the same time, specifically including: S301: The operator's fingerprint is identified by the electronic fingerprint lock 10. If the fingerprint information does not match the identity information data, the operator is determined to be a stranger, the door 2 is not opened, and the alarm is sounded; at the same time, if the operator is determined to be a stranger, the facial image of the stranger is collected through the first camera 201, and the fingerprint and facial image of the stranger are entered into the observation list.

[0073] S4a: If the information matches the identity data set, it is determined to be an insider, and the status of the oil pump 1 is determined. Based on the status of the oil pump 1, it is determined whether a single person is allowed to enter the safety protection device, specifically including: S401a: The operator's fingerprint is identified through the electronic fingerprint lock 10. If the fingerprint information matches the identity information data, the operator is determined to be an insider, and then the switch door 2 is opened. Since the switch door 2 is connected to the signal of the oil pump 1, the oil pump 1 stops working at this time; S402a: Monitor whether the oil pump 1 is in a shutdown state through the monitor; S403a: If the oil pump 1 is in a continuous shutdown state, a signal is sent through the alarm to allow the insider to enter the guardrail 6; S404a: If the oil pump 1 is in an intermittent or temporary shutdown state, a signal is sent through the alarm to prohibit the insider from entering the guardrail 6 until the insider leaves.

[0074] S3b: When multiple people enter the safety protection device, facial images are collected to determine whether anyone is on the observation list. If so, an alarm is issued; specifically including: S301b: The facial image of each person is collected through the first camera 201, and whether anyone is on the observation list is determined through the facial image. If so, an alarm is issued through the alarm.

[0075] S4b: If there is no person who matches the observation list, input the information data of at least one person. If the information data matches the identity data set, it is determined to be an internal person, and the state of the oil pump 1 is determined. Based on the state of the oil pump 1, it is determined whether multiple people are allowed to enter the safety protection device; specifically including: S401b: If not, input the fingerprint of at least one person into the electronic fingerprint lock 10. If the fingerprint matches the identity information data, it is determined that the operator is an internal person, and then the switch door 2 is opened;

[0076] S402b: After the switch door 2 is opened, the pumping unit 1 stops working;

[0077] S403b: monitoring whether the oil pump 1 is in a shutdown state through a monitor;

[0078] S404b: If the oil pump 1 is in a continuously shut down state, a signal is sent through the alarm to allow multiple people to enter the guardrail 6;

[0079] S405b: If the oil pump 1 is in an intermittent or temporarily shut down state, an alarm is used to send a signal prohibiting everyone from entering the guardrail 6 until everyone leaves.

[0080] In the above steps, the pump 1 can only allow internal personnel to enter when it is in the normal shutdown state. At least two conditions must be met to enter the safety protection device: (1) the internal personnel have entered their identity information in the safety protection device; (2) the pump 1 is in the normal shutdown state. Specifically, fingerprint recognition is used to determine whether the identity of the person is an internal person. If it is determined to be a stranger, the remote control personnel will be alerted to prevent the person from entering. In addition, if the person is an internal person, the remote control personnel will receive information that the switch door 2 has been opened after fingerprint recognition. At this time, the pump 1 can be shut down through the intelligent oil well system. Then the remote control personnel needs to confirm whether the pump 1 is in a continuous shutdown state. If the pump 1 is in a continuous shutdown state, the internal personnel are allowed to enter, otherwise they are prohibited from entering until the internal personnel leave.

[0081] In addition, it should be further explained that, in the case of multiple people entering, if one of them is already on the watch list, the internal personnel can request the remote control personnel to delete the corresponding person from the watch list and then re-identify him.

[0082] for Figure 1 The present invention also proposes a remote control safety protection device for the oil pumping unit 1, specifically, Figure 2 As shown, it includes an oil pumping unit 1, a switch door 2, a guardrail 6, an alarm module and a monitoring module.

[0083] Furthermore, if Figure 3 As shown, the switch door 2 is connected to the guardrail 6 through a hydraulic bearing hinge 13; a buffer door closer 12 is also connected between the top of the switch door 2 and the guardrail 6; a handle 11, an electronic fingerprint lock 10 and a first camera 201 are installed on the surface of the switch door 2, the electronic fingerprint lock 10 is located on the lower side of the handle 11, and the first camera 201 is installed on the upper side of the electronic fingerprint lock 10.

[0084] It should be noted that the switch door 2 is connected to the guardrail 6 through a hydraulic bearing hinge 13, which satisfies the instant opening and closing effect of the switch door 2, and reduces the risk of strangers following people in the identity data set into the guardrail 6. In addition, the switch door 2 can be set as a transparent door, without visual blind spots, which is convenient for outsiders to observe the internal situation of the safety guardrail.

[0085] Furthermore, combined with Figure 2 and Figure 4It can be seen that the guardrail 6 includes: a top frame, a closed structure formed by connecting several transverse tubes 7 end to end; a supporting frame, composed of several fixed tubes 8 perpendicular to the transverse tubes 7 and fixedly connected to the transverse tubes 7; a plurality of protective nets 6 are provided, and elastic steel bars 14 are fixedly connected on both sides of each protective net 6, and a hook 15 is installed on one side of the elastic steel bar 14, and the hook 15 is fixedly connected to the fixed tube 8, and one end of the elastic steel bar 14 is fixedly connected to the transverse tube 7.

[0086] It should be noted that in Figure 2 In the embodiment, the transverse pipe 7, the fixed pipe 8, the elastic steel bar 14, etc. are all connected by welding. A steel rectangular guardrail 6 of (7.0m-8.0m)×(4.0m-5.0m)×2.0m (depending on the size of the specific pumping unit 1) is built around the pumping unit 1. A switch door 2 is opened on one side of the guardrail 6. The specific sizes of the switch door 2 and the guardrail 6 can be freely adjusted.

[0087] Furthermore, the alarm module includes an electronic horn 3, a first fixed rod 4 and a first fixed support 5, wherein the electronic horn 3 is used to issue an alarm message; the top of the first fixed rod 4 is used to install the electronic horn 3; the first fixed support 5 is located on the ground and is used to install the first fixed rod 4.

[0088] Furthermore, the monitoring module includes a second camera 9, a second fixed rod 16 and a second fixed support 17, wherein the second camera 9 is used to monitor the safety protection device; the top of the second fixed rod 16 is used to install the second camera 9; the second fixed support 17 is located on the ground and is used to install the second fixed rod 16.

[0089] It should be noted that a second camera 9 is installed near the guardrail 6 to monitor the entry and exit of the guardrail 6; an electronic speaker 3 is installed in the corner of the well site, and the remote monitoring personnel can shout to the well site through the electronic speaker 3. In addition, the electronic speaker 3 in the above device corresponds to the alarm in the method, and the second camera 9 corresponds to the monitor in the method.
