Description

Technical Field

[0001] This utility model belongs to the field of automated control technology for oil and gas drilling operations, specifically relating to an intelligent lighting system for drilling sites. Background Technology

[0002] In existing oil and gas drilling operations, well site lighting systems are crucial for ensuring safe production at night and in low-light conditions. Currently, most drilling teams employ a purely manual, mechanical management model for well site lighting control. Specifically, the power supply to all lighting fixtures on the well site, including those in the drilling rig area, well site foundation, pump room, machine room, and material storage areas, is entirely controlled manually by on-site personnel, primarily the machine room operator and drilling rig staff.

[0003] The workflow of this mode is as follows: When dusk falls or the weather changes and the ambient light dims, the staff on duty, based on their subjective visual perception, determine whether the lighting needs to be turned on, and then go to the power control boxes located in various places to manually turn on the power switches. Conversely, at dawn or when the light is considered sufficient, the power is manually turned off.

[0004] This manual control model essentially relies entirely on the sense of responsibility, subjective judgment, and immediate reaction of personnel for a technical action that should be standardized and continuous. Although it has been used in traditional drilling operations for a long time, as the industry's requirements for safe production, cost reduction and efficiency improvement, and refined management continue to increase, the inherent defects of this model have become increasingly prominent, and it can no longer meet the needs of modern intelligent drilling operations.

[0005] The existing manual well site lighting methods described above have the following significant drawbacks: (1) Low energy efficiency leads to continuous economic losses. Because the operation of lighting relies entirely on human intervention, its effective working time cannot be precisely controlled, leading to a significant waste of electricity. Specifically: ① Widespread delayed shutdown: In the early morning, when it is already bright enough, workers are often busy with equipment inspections, shift handover preparations, or other urgent tasks, leaving the lights ineffective for several hours. ② Unnecessary early activation: In the evening, to avoid being left in darkness due to forgetfulness, workers often turn on the lights early, even though the ambient light level is still sufficient for basic operations. ③ Huge cumulative energy consumption: Drilling site lighting typically uses high-power floodlights, metal halide lamps, and other equipment, resulting in a large number of lamps and a high total power consumption. This "lights on forever" phenomenon leads to accumulated ineffective operating time, generating huge amounts of unnecessary electricity expenditure, seriously violating the core management goal of cost reduction and efficiency improvement in current drilling operations.

[0006] (2) There are significant security management loopholes, which could easily lead to security accidents. The reliability and timely operation of the lighting system are directly related to the operational safety of the entire well site. The existing manual control system has serious shortcomings in this regard: ① Lack of lighting guarantee in rainy weather: In adverse weather conditions such as rain, fog, and sandstorms during the day, the on-site illuminance will suddenly decrease. If the person in charge fails to notice in time or is busy with other matters and neglects to turn on the lighting, the visibility of the entire work site will drop sharply. The dim environment greatly increases the risk of workers slipping, falling, bumping, and mechanical injuries. At the same time, inspection personnel may find it difficult to detect abnormalities such as leaks, spills, drips, and leaks in key areas such as the wellhead, manifolds, and mud tanks, potentially delaying the best time to handle accidents. ② Increased risk of electric shock: This is a particularly serious potential risk. In rainy weather, the site is slippery, and the insulation performance of electrical equipment casings and wiring may decrease due to moisture. Workers are forced to manually close the power control box in the rain when visibility is insufficient. This process involves operating with wet hands, walking in waterlogged areas, and touching live switch boxes, greatly increasing the probability of electric shock accidents. The existing technical solution itself has become a trigger point for a security vulnerability.

[0007] (3) Inappropriate allocation of human resources and low management efficiency Ambiguous Responsibilities and Dependency Mentality: Assigning control responsibilities to multiple positions simultaneously (such as machine room operator and drilling rig personnel) can easily lead to unclear boundaries of responsibility, fostering dependency and potentially resulting in a situation where no one is truly accountable. Disruption to Core Operational Processes: The core of drilling operations lies in critical tasks such as driller, equipment maintenance, and monitoring. Frequently distracting technicians with simple, repetitive operations like switching lights on and off disrupts the continuity and focus of their core work, representing an inefficient use of highly skilled human resources and reducing overall operational efficiency. Lack of Objective Standards and Effective Supervision: Decisions regarding turning lights on and off lack objective, quantifiable standards for illumination levels, varying entirely from person to person. This hinders refined management and makes supervision and evaluation lack a basis. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent lighting system for drilling sites, so as to achieve on-demand, automatic, safe and efficient lighting operation.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drilling site intelligent lighting system includes lighting fixtures and switches, with the lighting fixtures connected to a power source via the switches; it also includes an intelligent control module, a controller, and a light sensor; The intelligent control module includes an edge computing gateway, a power supply submodule, and a communication submodule; the output of the power supply submodule is connected to the power input of the edge computing gateway and the communication submodule, respectively. The signal output of the light sensor is wirelessly connected to the signal input of the edge computing gateway via a communication submodule; the signal output of the edge computing gateway is wirelessly connected to the controller via a communication submodule. The controller's signal output terminal is connected to the switch's command input terminal.

[0010] As a limitation, the intelligent control module is installed in the power distribution room cabinet room.

[0011] As a second limitation, the controller is installed before the lighting circuit of the explosion-proof power box included in the drilling site intelligent lighting system.

[0012] As a third limitation, the light sensor is installed at the illuminance collection point.

[0013] As a fourth limitation, both the light sensor and the controller are equipped with explosion-proof housings. The light sensor and the controller are directly attached to the metal equipment corresponding to the installation location by strong magnetism through their respective explosion-proof housings.

[0014] As the fifth type of limitation, the light sensor model is AS-22DL.

[0015] As the sixth type of limitation, the controller model is NRF24L01.

[0016] As the seventh type of limitation, the model of the edge computing gateway is E870-EG01.

[0017] As the eighth type of limitation, the communication submodule is designated as LoRa-TM-01.

[0018] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned technical solution, are as follows: (1) This utility model utilizes the light intensity to automatically start and stop the on-site lighting. All modules are controlled by wireless transmission. The sensor controller collects light sensing signals and wirelessly transmits them to the communication submodule. After the edge computing gateway calculates the signals, it sends a switch command to the controller through the communication submodule to control the lights to turn on or off, thereby realizing intelligent control of the lighting fixtures and enabling on-demand, automatic, safe and efficient operation of the lighting. (2) In this utility model, the light sensor and the controller are respectively provided with explosion-proof shells, and the two are fixedly installed with strong magnets, which can be better suited to the working environment of oil drilling sites; (3) This utility model installs the intelligent control module in the power distribution room cabinet, which not only facilitates the power supply sub-module to supply power to each circuit of the intelligent control module, but also reduces the interference of the power supply sub-module and avoids communication interference failures in the wireless transmission of each module. Installing it in the power distribution room cabinet does not require the installation of an explosion-proof shell, thus reducing cost investment. (4) In this utility model, the intelligent control module is the control center. Each drilling site intelligent lighting system only needs one intelligent control module to achieve control. After receiving the light sensor signal collected by the light sensor, the internal program analyzes and calculates the signal and sends a switch command to the controller. The controller consists of a power supply module, a wireless receiving module, and a switch execution module, which are directly connected in series in the lighting circuit. Each lighting circuit needs to be connected in series with one controller. The switch execution module is defined as the power-off switch closed state. In order to ensure the normal operation of the lighting quickly when the drilling site intelligent lighting system fails, it is only necessary to turn off the power of the controller, close the switch execution module to connect the lighting circuit of this circuit, restore the lighting circuit to the original state, and manually control the lighting switch to avoid the safety hazards of the well site lighting when the intelligent lighting system fails.

[0019] This utility model belongs to the field of automated control technology for oil and gas drilling operations, and can realize on-demand, automatic, safe and efficient operation of lighting. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example As a crucial operational site for oil and gas exploration and development, the lighting system at drilling sites plays a vital role in ensuring safety and improving efficiency during nighttime operations. Traditional drilling site lighting systems typically rely on manual control, which suffers from problems such as untimely lighting, energy waste, and management difficulties. Especially under harsh environmental conditions, such as rain, snow, and sandstorms, manual operation of lighting equipment is not only inefficient but also increases operational risks. Furthermore, the complex environment of drilling sites, involving flammable and explosive materials, places high demands on the explosion-proof performance of lighting equipment.

[0024] With the development of the Internet of Things, edge computing, and smart sensing technologies, smart lighting systems are being used more and more widely in the industrial field.

[0025] like Figure 1As shown, this embodiment provides an intelligent lighting system for drilling sites, including lighting fixtures and switches, with the lighting fixtures connected to a power source via the switches; it also includes an intelligent control module, a controller, and a light sensor.

[0026] The intelligent control module includes an edge computing gateway, a power supply submodule, and a communication submodule; the output of the power supply submodule is connected to the power input of the edge computing gateway and the communication submodule, respectively.

[0027] The signal output of the light sensor is wirelessly connected to the signal input of the edge computing gateway via a communication submodule; the signal output of the edge computing gateway is wirelessly connected to the controller via a communication submodule. The signal output of the controller is connected to the command input of the switch.

[0028] In this embodiment, the intelligent control module is installed in the power distribution room cabinet. The cabinet is designed to be dustproof and moisture-proof, and equipped with a cooling fan to ensure stable operation of the module in high-temperature environments. The controller is installed before the explosion-proof power box lighting circuit included in the drilling site intelligent lighting system. The light sensor is installed at the illuminance acquisition point.

[0029] In this embodiment, both the light sensor and the controller are equipped with explosion-proof housings made of cast aluminum. The light sensor and the controller are each fitted with a strong magnetic base on their respective explosion-proof housings, and are directly attached to the metal equipment corresponding to the installation location by means of strong magnetism.

[0030] Specifically, in this embodiment, the lighting fixtures are high-brightness, low-power LED explosion-proof lights, suitable for the harsh environment of drilling sites. The lighting fixtures are connected to the power supply via a switch, which is an intelligent relay switch supporting remote control and manual override functions, ensuring that lighting control can still be achieved through manual intervention even if the automatic control system fails. The installation locations of the lighting fixtures cover key areas of the drilling site, such as the drilling platform, mud circulation area, and equipment storage area, ensuring comprehensive lighting without blind spots.

[0031] Edge computing gateways utilize high-performance embedded processors and have built-in real-time operating systems, supporting multiple communication protocols such as MQTT and CoAP. They possess data storage and analysis capabilities, processing illuminance data uploaded by light sensors in real time and automatically generating control commands based on preset thresholds. Edge computing gateways also support remote configuration and firmware upgrades, facilitating system maintenance and functional expansion.

[0032] Specifically, in this embodiment, the edge computing gateway is model E870-EG01, which is an industrial-grade edge computing gateway based on Node-RED visual programming. It supports multiple industrial protocols such as Modbus and MQTT and has local data processing capabilities to reduce cloud transmission load.

[0033] Power Supply Submodule: Provides a stable and reliable power supply for the intelligent control module. The power supply submodule uses a wide 24V DC power supply and supports overvoltage, overcurrent, and short-circuit protection, ensuring stable operation in industrial environments with large voltage fluctuations. The output of the power supply submodule is connected to the edge computing gateway and communication submodule through an isolation circuit to prevent electromagnetic interference.

[0034] Communication Submodule: Responsible for the system's wireless communication functions. The communication submodule supports multiple wireless communication methods such as 4G / 5G, Wi-Fi, and LoRa, and can be flexibly configured according to the network coverage of the well site. The communication submodule connects to the edge computing gateway via a serial port or Ethernet interface to achieve high-speed data transmission. The model number of the communication submodule is LoRa-TM-01.

[0035] The light sensor employs a high-precision photoelectric sensor with a measurement range of 0-100,000 Lux and an accuracy of ±5%. The sensor incorporates a signal conditioning circuit to preprocess the collected illuminance data and uploads it wirelessly to the edge computing gateway. The light sensor model is AS-22DL. It also features an explosion-proof housing and is magnetically attached to the illuminance collection point, such as a pillar or equipment surface around the well site. Install the light sensor at the well site illuminance collection point (e.g., the edge of the work area, top of equipment). Clean the metal parts of the mounting surface and secure the light sensor with strong magnetic attachment. Connect the sensor power supply and adjust the sensor probe direction to ensure accurate ambient illuminance sensing. Register the sensor device and set the data upload frequency through the intelligent control module's management platform. The light sensor itself includes a power supply and wireless transmission module, making it a crucial component of the entire drilling site intelligent lighting system. Its installation location must not be covered by nighttime lighting to avoid erroneous signal acquisition due to light irradiation. A single light sensor is required for the entire drilling site intelligent lighting system.

[0036] The controller is the system's execution unit, responsible for receiving instructions from the edge computing gateway and controlling the switching of lighting fixtures. The controller uses an industrial-grade microcontroller, supports multiple relay outputs, and can simultaneously control multiple lighting circuits. The controller model is NRF24L01. The controller is installed before the lighting circuit in the explosion-proof power box, fixed to the metal equipment surface via strong magnetic adsorption, making installation simple and secure. The controller housing is explosion-proof, meeting Ex d IIC T6 explosion-proof rating, suitable for flammable and explosive environments. Select a suitable location to install the controller before the lighting circuit in the explosion-proof power box. Utilize the strong magnet of the controller's explosion-proof housing to directly adsorb it onto the metal surface of the power box. Connect the controller's input and output lines, ensuring they are correctly connected in series with the lighting circuit switches. After powering on, use the intelligent control module's configuration tool to assign addresses and perform functional tests on the controller.

[0037] Specifically, in this embodiment, an intelligent control module is installed in the cabinet room of the power distribution room and connected to the network. This module is used to link with a controller and a light sensor, both equipped with explosion-proof enclosures. The controller connects to a communication submodule located in the power distribution room via wireless communication technology, receiving instructions from the edge computing gateway to control the on / off state of the lighting fixtures in this circuit. A light sensor with an explosion-proof enclosure is installed at the illuminance collection point and connected to power. This sensor measures the on-site illuminance in real time and transmits the collected illuminance data to the edge computing gateway in real time via wireless communication, providing data support for automatic lighting control. The edge computing gateway compares the received illuminance data with a built-in illuminance data threshold. If the real-time illuminance data is greater than the built-in threshold, it sends a light-off command to the controller, which then turns off the corresponding lighting fixture via a corresponding switch. Conversely, if the illuminance data is less than the threshold, it sends a light-on command to the controller, which then turns on the corresponding lighting fixture via a corresponding switch.
