DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] Some valve room monitoring systems may not work properly due to harsh environments, such as high or low temperatures, and the equipment in the valve room may not be able to send pipeline data to remote monitoring equipment. Some valve room monitoring systems may not be able to send pipeline data to remote monitoring equipment uninterruptedly due to remote locations and insufficient power supply. All of the above will cause the remote monitoring equipment to be unable to obtain pipeline data in a timely manner.

[0052] In order to solve the above problems, this embodiment provides a valve chamber monitoring system, which can maintain a constant operating temperature in the valve chamber and can also continuously send pipeline data to a remote monitoring device.

[0053] like Figures 1 to 3 As shown, the monitoring system includes an equipment room 1, a control device 2, a power distribution device 3, a communication device 4 and a HVAC device 5; the control device 2, the power distribution device 3 and the communication device 4 are all located in the equipment room 1, and the HVAC device 5 is fixed to the wall of the equipment room 1; Figure 3As shown, the control device 2 is electrically connected to the power distribution device 3, the communication device 4 and the HVAC equipment 5 respectively, and the power distribution device 3 is electrically connected to the communication device 4 and the HVAC equipment 5 respectively; the control device 2 is configured to obtain the pipeline data in the valve room where the equipment room 1 is located, and send the pipeline data to the remote monitoring device through the communication device 4; control the temperature in the equipment room 1 to be within the target temperature range through the HVAC equipment 5; and control the power distribution device 3 to continuously supply power to the valve room monitoring system.

[0054] Among them, Figure 1 The structure diagram of equipment room 1 is shown as follows: Figure 2 The diagram is a top view of the structure of the equipment room 1. Figure 3 The figure shows the connection relationship diagram of the equipment in equipment room 1.

[0055] The equipment room 1 is arranged along the oil and gas pipeline, and multiple equipment are installed inside. It can also be called a cabinet room. Multiple equipment rooms 1 can be arranged in the valve room along the oil and gas pipeline according to actual needs. Figure 1 and Figure 2 As shown, the equipment room 1 can be a sealing device surrounded by multiple walls, for example, it can be a skid-mounted integrated equipment room, which enables the valve room monitoring system to be movable and improves the flexibility of the location of the valve room monitoring system.

[0056] Among them, the combustion performance level of equipment room 1 is Class A to avoid fire in a dry environment, thereby improving the safety of the valve room monitoring system.

[0057] The equipment room 1 may be made of a material with good thermal insulation performance to ensure that the temperature in the equipment room 1 is within a relatively stable range.

[0058] like Figure 1 As shown, the equipment room 1 may have a room structure or a box structure, etc. The wall, top wall and base of the equipment room 1 enclose a chamber 10. The wall of the equipment room 1 is also equipped with a safety door 13 to facilitate the entry and exit of technicians and can also be used for ventilation. The control device 2, the power distribution device 3 and the communication device 4 can all be located in the equipment room 1, for example, Figure 2 As shown, the chamber 10 of the equipment room 1 may include multiple rows of cabinets 6 , and the control equipment 2 , the power distribution equipment 3 and the communication equipment 4 may be installed in the multiple rows of cabinets 6 .

[0059] The control device 2 may be an RTU (Remote Terminal Unit), which is a computer measurement and control unit with a modular structure designed for long communication distances and harsh industrial field environments.

[0060] The control device 2 may be configured with a controller, an I / O (Input / Output) module, a communication interface module, etc., and data processing and instruction processing, etc., may be implemented through the controller.

[0061] In one example, the control device 2 can be used to obtain pipeline data in the valve chamber of the oil and gas pipeline where the valve chamber monitoring system is located. These pipeline data may include but are not limited to the pressure value of the medium in the pipeline, the temperature of the medium in the pipeline, the flow rate of the medium in the pipeline, the opening of the valve of the pipeline, and the corrosion data of the pipeline.

[0062] The control device 2 can obtain the pressure value of the medium in the pipeline through the pressure instrument, obtain the temperature of the medium in the pipeline through the temperature sensor, obtain the valve opening through the valve controller of the pipeline, and obtain the corrosion condition of the pipeline through the cathodic protection system. The cathodic protection system can be located in the equipment room 1, and the cathodic protection system has a serial port to realize data transmission with the control device 2.

[0063] In one example, the control device 2 can also be used to send pipeline data to a remote monitoring device, wherein the remote monitoring device can be a central control station that is relatively far away from the oil and gas pipeline station. Accordingly, the control device 2 is electrically connected to the power distribution device 3, the communication device 4 and the HVAC device 5 respectively, so that the power distribution device 3 provides power to the control device 2, and the control device 2 controls the power distribution device 3 to supply power to the valve room monitoring system, and the control device 2 can communicate with the remote monitoring device through the communication device 4, and can also control the HVAC device 5 to increase or decrease the temperature.

[0064] The power distribution equipment 3 is used to provide uninterrupted power supply to the valve room monitoring system.

[0065] In one example, the valve chamber monitoring system can be powered by solar energy or wind energy, etc. Since solar energy and wind energy are not very stable, the valve chamber monitoring system can also be powered by AC power. Accordingly, the power distribution equipment 3 has a AC power interface, and the electrical equipment in the valve chamber monitoring system are all electrically connected to the AC power interface.

[0066] In order to minimize energy consumption, the power distribution equipment 3 includes a solar power supply component; the solar power supply component is electrically connected to the control device 2, the communication device 4 and the HVAC equipment 5 respectively; the control device 2 is specifically configured to, when it is detected that the power reserve of the solar power supply component is higher than the power threshold, control the solar power supply component to supply power to the valve room monitoring system; when it is detected that the power reserve of the solar power supply component is not higher than the power threshold, switch to the mains power supply to supply power to the valve room monitoring system.

[0067] The power threshold is mainly related to the total power consumption of all electrical devices in the valve room monitoring system. For example, the power threshold is higher than the power corresponding to the total power consumption of all electrical devices in the valve room monitoring system.

[0068] In one example, the solar power supply is electrically connected to the electrical equipment of the valve chamber monitoring system. When the solar power supply has sufficient power reserve, the solar power supply is used preferentially to power the electrical equipment of the valve chamber monitoring system. When the solar power supply has less power reserve, the AC power can be used to power the electrical equipment of the valve chamber monitoring system.

[0069] In this way, when the control device detects that the power reserve of the solar power supply component is higher than the power threshold, it can control the solar power supply component to power the valve chamber monitoring system. When it detects that the power reserve of the solar power supply component is lower than the power threshold, it can switch to AC power to power the valve chamber monitoring system, thereby ensuring uninterrupted operation of the valve chamber monitoring system.

[0070] In order to further ensure that the valve room monitoring system can work uninterruptedly, the power distribution equipment 3 also includes a generator power supply; the generator power supply is electrically connected to the control device 2, the communication equipment 4 and the HVAC equipment 5 respectively; the control device 2 is specifically configured to control the generator power supply to supply power to the valve room monitoring system when it is detected that the power reserve of the solar power supply is not higher than the power threshold and the city power is in a power outage state.

[0071] In one example, in remote areas, the city power supply may be interrupted. In order to ensure the uninterrupted operation of the valve chamber monitoring system, a generator power supply can be used to power the valve chamber monitoring system when the solar power supply is insufficient or the city power supply is interrupted.

[0072] In this way, when the control device 2 detects that the power of the solar power supply is higher than the power threshold, it can control the solar power supply to supply power to the valve room monitoring system. When it detects that the power of the solar power supply is lower than the power threshold and the city power is in a normal power supply state, it switches to the city power supply to supply power to the valve room monitoring system. When it detects that the power of the solar power supply is lower than the power threshold and the city power is in an interrupted state, it can control the generator power supply to start working and supply power to the valve room monitoring system. In addition, the uninterrupted operation of the valve room monitoring system can be ensured.

[0073] In one example, in order to ensure that the control device 2 can continue to work, and also to ensure that the normal operation of each device in the valve room monitoring system is not affected when switching the power supply, the power distribution equipment 3 also includes a battery component, which is electrically connected to the AC power and the solar power supply respectively; the battery component is also electrically connected to the control device 2, the communication equipment 4 and the HVAC equipment 5 respectively.

[0074] The capacity of the battery component is higher than the amount of electricity corresponding to the total power consumption of the valve chamber monitoring system, so as to ensure that the battery component can stably supply power to the valve chamber monitoring system.

[0075] The operating temperature of the battery component is within the range of -30°C to 40°C.

[0076] In this way, when the solar power supply device supplies power to the valve chamber monitoring system, the battery device can be charged to store electric energy. When the city power supply supplies power to the valve chamber monitoring system, the battery device can also be charged to store electric energy. When the generator power supply device supplies power to the valve chamber monitoring system, the battery can also be charged to store electric energy.

[0077] In order to achieve fast charging of the battery, when the mains is used for power supply, the mains interface can achieve a power increase of 40% to 90% in 5 hours when charging the battery. Similarly, when the solar power supply and the generator power supply are used for power supply, the battery can achieve a power increase of 40% to 90% in 5 hours.

[0078] In one example, the battery unit is electrically connected to the electrical equipment in the valve chamber monitoring system, for example, it can be electrically connected to all the electrical equipment in the valve chamber monitoring system, or it can be electrically connected to some major electrical equipment in the valve chamber monitoring system. This embodiment does not limit this, and technicians can flexibly choose which electrical equipment the battery unit supplies power to according to actual needs.

[0079] In this way, during the process of the control device 2 switching the power supply of the power distribution device 3, the normal operation of the valve room monitoring system can also be ensured.

[0080] The number of solar power supply components and generator power supply components can be flexibly selected by technicians according to actual conditions. For example, for a larger valve room monitoring system, more solar power supply components and more generator power supply components can be configured.

[0081] Based on the above, the valve room monitoring system realizes redundant power distribution through the mains, solar power supply and generator power supply, which can ensure the uninterrupted operation of the valve room monitoring system and the uninterrupted sending of pipeline data to the remote monitoring equipment.

[0082] The communication device 4 is a device used to enable the control device 2 to communicate with a remote monitoring device.

[0083] In one example, the communication device 4 may include a switch, for example, at least two switches, one of which is used as a main switch and the other switches are used as secondary switches. When the main switch is normal, the main switch forwards data, and when the main switch fails, the secondary switches forward data, so as to ensure that the valve room monitoring system can continuously send pipeline data to the monitoring device at the remote end.

[0084] Correspondingly, such as Figure 4 As shown, the communication device 4 may include a main switch 41 and a sub-switch 42, the main switch 41 is electrically connected to the control device 2 and the power distribution device 3, respectively, and the sub-switch 42 is electrically connected to the control device 2 and the power distribution device 3, respectively; the control device 2 is specifically configured to, when it is detected that the main switch 41 is in a normal working state, send the pipeline data to the remote monitoring device through the main switch 41; when it is detected that the main switch 41 is in a fault state, send the pipeline data to the remote monitoring device through the sub-switch 42.

[0085] The number of the sub-switches 42 may be one or more.

[0086] Among them, the main switch 41 and the sub-switch 42 can both be industrial Ethernet switches with three-layer routing and forwarding functions, supporting standard protocols such as 802.1d, 802.1p / q, 802.1s, 802.1w, 802.1×, 802.3ad, and 802.3u.

[0087] In one example, if Figure 4 As shown, the communication device 4 may further include an optical component 43. The main switch 41 and the sub-switch 42 are both connected to the optical component 43 via optical fibers. The optical component 43 is connected to a remote monitoring device via optical fibers.

[0088] In one example, the business boards of the main switch 41 and the sub-switch 42 both have network ports, and the control device 2 also has a network port. The network port of the control device 2 can be connected to the network ports of the main switch 41 and the sub-switch 42 respectively through a Category 5 twisted pair cable, so that the control device 2 can send data to the main switch 41 or the sub-switch 42 to forward it to a remote monitoring device.

[0089] The HVAC equipment 5 is used for heating in a relatively low temperature environment and for ventilation and heat dissipation in a relatively high temperature environment, so that the temperature in the equipment room 1 can be maintained within the target temperature range.

[0090] The target temperature range is a temperature range in which the equipment in equipment room 1 can work normally.

[0091] The HVAC equipment 5 is provided with a serial connection port to facilitate connection with the control device 2 , and the electrical connection between the HVAC equipment 5 and the control device 5 can be connected via a common cable.

[0092] In one example, if Figure 2 As shown, the HVAC equipment 5 may include an air conditioner 51, an air intake fan 52, and an exhaust fan 53. The air conditioner 51 may be installed in the chamber 10 of the equipment room 1 or on the wall of the equipment room 1. Figure 1 As shown, the first wall 11 of the equipment room 1 has an air conditioning installation opening 111. Figure 2 As shown, the air conditioner 51 can be installed in the air conditioner installation opening 111. The first wall 11 can be any wall of the equipment room 1.

[0093] The air intake fan 52 and the exhaust fan 53 can be installed on the wall or top wall of the equipment room 1. For example, the air intake fan 52 can be installed on the top wall of the equipment room 1, and the exhaust fan 53 can be installed on the wall of the equipment room 1. For another example, the air intake fan 52 and the exhaust fan 53 can be installed on different walls of the equipment room 1.

[0094] Exemplarily, one wall of the equipment room 1 has an air inlet installation opening, and the air inlet fan 52 can be installed in the air inlet installation opening. Another wall of the equipment room 1 has an exhaust fan installation opening, and the exhaust fan 53 is installed in the exhaust fan installation opening.

[0095] The air inlet fan 52 and the air exhaust fan 53 are positioned opposite to each other to improve ventilation performance.

[0096] For example, Figure 1 As shown, the first wall 11 of the equipment room 1 has an air inlet installation opening 112, and the air inlet fan 52 is installed in the air inlet installation opening 112. The second wall 12 of the equipment room 1 has an exhaust fan installation opening 121, and the exhaust fan 53 is installed in the exhaust fan installation opening 121. The first wall 11 and the second wall 12 are opposite to each other.

[0097] The air inlet fan 52 installed on the first wall 11 and the exhaust fan 53 installed on the second wall 12 may be at the same height or at different heights. This embodiment does not limit this, as long as the positions of the first wall 11 and the second wall 12 are relative.

[0098] In one example, the control device 2 can control the HVAC equipment 5 to dissipate heat for the valve room monitoring system in accordance with the principle of consuming the least energy. For example, when the control device 2 detects that the current temperature is higher than the temperature threshold, and the difference between the current temperature and the temperature threshold is in the first temperature range, ventilation and heat dissipation can be performed by opening a window or opening a safety door 13. For another example, when the control device 2 detects that the current temperature is higher than the temperature threshold, and the difference between the current temperature and the temperature threshold is in the second temperature range, the air intake fan 52 and the exhaust fan 53 can be turned on to dissipate heat for the valve room monitoring system. For another example, when the control device 2 detects that the current temperature is higher than the temperature threshold, and the difference between the current temperature and the temperature threshold is in the third temperature range, the air conditioner 51 can be controlled to cool the valve room monitoring system. Among them, the first temperature range is smaller than the second temperature range and smaller than the third temperature range.

[0099] The temperature threshold is related to the operating temperature of the equipment in the valve room monitoring system, and is a temperature that enables the main equipment to work normally.

[0100] Based on the above, the power distribution equipment 3 of the valve chamber monitoring system includes a solar power supply component and a generator power supply component. In terms of power supply, redundant power supply by municipal power, solar power supply and generator power supply can reduce or even avoid power interruption, thereby ensuring the uninterrupted operation of the valve chamber monitoring system.

[0101] The HVAC equipment 5 of the valve room monitoring system includes an air conditioner 51, an air intake fan 52 and an exhaust fan 53. Through the cooling and heating functions of the air conditioner 51 and the ventilation functions of the air intake fan 52 and the exhaust fan 53, it can ensure that the temperature in the equipment room 1 is maintained within a relatively suitable range, thereby ensuring the normal and uninterrupted operation of the equipment in the valve room monitoring system.

[0102] The communication equipment 4 of the valve room monitoring system includes at least two switches, one as the main switch and the rest as sub-switches, which are backup switches. In this way, even if the main switch fails, pipeline data can be sent to the remote monitoring device through the sub-switches, thereby ensuring that the valve room monitoring system continuously sends pipeline data to the remote monitoring device.

[0103] It can be seen that the valve room monitoring system can automatically switch the power supply to ensure that the equipment of the valve room monitoring system can work uninterruptedly, can automatically maintain a suitable temperature range, ensure that the equipment of the valve room monitoring system can work uninterruptedly, and can automatically select a normal switch to send data to the monitoring equipment. It can be seen that even if the valve room monitoring system is located in a remote location or a harsh environment, the control equipment can continuously send data to the remote monitoring equipment, so that the remote monitoring equipment can obtain various parameters in the oil and gas pipeline station in a timely manner.

[0104] Moreover, in terms of switching power supply, the valve room monitoring system can be powered by solar energy first, followed by city power supply, and finally by generator power supply, which is beneficial to saving energy.

[0105] Moreover, in terms of heat dissipation, the valve room monitoring system can dissipate heat for the valve room monitoring system according to the temperature conditions within the valve room monitoring system and the principles of dissipating heat by opening windows and safety doors, starting the air intake and exhaust fans, and starting air conditioning. On the basis of ensuring effective heat dissipation, the method with the least energy consumption is selected for heat dissipation, which helps to reduce energy consumption.

[0106] The valve room monitoring system can be Figure 5 The process shown establishes:

[0107] Before establishing the valve room monitoring system, the technicians may first determine the environment of the area where the valve room monitoring system is located.

[0108] For example, local outdoor meteorological parameters are collected, including but not limited to the average annual temperature, the average temperature of the hottest month, the highest temperature in summer, the average temperature of the coldest month, the lowest temperature in winter, the average annual rainfall, the maximum annual rainfall, the minimum annual rainfall, the average annual snow thickness, the maximum annual snow thickness, the minimum annual snow thickness, the average wind speed, the maximum annual wind speed, the maximum permafrost depth over many years and the number of sunshine hours, etc.

[0109] The above data is mainly used to formulate reasonable heat dissipation and insulation plans for the valve room monitoring system in the later stage, so as to reduce losses and save energy while meeting the heat dissipation and insulation requirements.

[0110] In step 1, determine the functions that the valve room monitoring system needs to complete.

[0111] The functions that the valve room monitoring system needs to complete may include the acquisition of pipeline data, such as pipeline pressure, medium temperature in the pipeline, medium flow in the pipeline and pipeline corrosion conditions, etc. It may also include process monitoring, power generation and distribution function monitoring, as well as signal relay functions and fire monitoring functions.

[0112] In step 2, the electrical equipment in the equipment room, the power consumption of the electrical equipment, the thermal conversion efficiency and the selection of the energy storage unit are determined.

[0113] 1) Configure power equipment, HVAC equipment, instrument equipment, communication equipment, and cathodic protection equipment according to the functions determined in step 2

[0114] 2) Determine the power consumption and conversion efficiency of the equipment according to the configuration equipment, and select the battery components.

[0115] In step 3, conduct a hazard and operability analysis of the layout and electrical equipment in the equipment room.

[0116] For example, based on the equipment selected in the above steps and the layout of the equipment in the equipment room, conduct hazard analysis and risk assessment, identify potential hazardous events, and make corresponding improvements to ensure that risks are controllable and there is neither excessive protection nor insufficient protection.

[0117] The analysis activities shall include but not be limited to the following:

[0118] 1) Determine the risk tolerance standard in combination with emergency classification regulations, enterprise system documents and management models.

[0119] 2) The analysis is carried out with the skid-mounted integrated equipment room and its ancillary equipment as nodes. The analysis process should fully consider the effectiveness, independence and auditability of existing protection measures. Existing protection measures include but are not limited to fire protection measures inside the battery unit, fire protection measures between battery units, enclosure structure materials, and the distribution of the skid-mounted integrated equipment room in the oil and gas pipeline valve room.

[0120] 3) Identify the different scenarios of each risk point one by one, organize the multiple causes and corresponding consequences of the same risk point into cause-consequence pairs, record and archive them.

[0121] 4) Based on the results of the analysis in 3), recommendations are given for scenarios with residual risk ≥ Level II, and the risks are ensured to be acceptable after the recommendations are effectively implemented.

[0122] In step 4, determine the layout of electrical equipment.

[0123] For example, the floor plan of the equipment room can be arranged based on the space occupied by the equipment and the subsequent equipment maintenance requirements.

[0124] In step 5, determine the material, wall thickness, and ventilation plan for the equipment room.

[0125] 1) Determine the fire resistance grade of the synthetic material based on the area inside the valve room where the equipment room is located.

[0126] 2) Determine the thickness of the wall, ceiling and base material of the equipment room based on the external wind load, internal equipment load and heat loss of the equipment in winter.
