Description

Technical Field

[0001] The present invention relates to the technical field of petrochemical crude oil production, and more specifically, to a control system and method for linking a fire and gas system with a video monitoring system. Background Art

[0002] The central control fire and gas system and video surveillance system of an oil well platform are two independent systems. The fire and gas system is mainly responsible for fire detection and alarm at the facility site, while the video surveillance system is responsible for real-time monitoring and recording of the site situation. If a fire or other dangerous situation occurs on site, personnel will manually operate the video system to view it. This method is very demanding on the emergency response and operation capabilities of personnel, and has the following shortcomings in actual application:

[0003] 1) Information isolation and poor linkage. When a fire occurs, the central control fire and gas system can only trigger a local alarm and cannot automatically link with the video surveillance system for on-site monitoring and recording, which increases the reaction time for accident handling and reduces the efficiency of emergency response.

[0004] 2) Lack of coordination mechanism leads to low resource utilization. The two systems run independently and cannot share resource information, resulting in resource waste.

[0005] 3) Inconvenient management. In case of emergency, it is necessary to monitor these two independent systems separately. In particular, the video surveillance system requires manual operation to retrieve images of the dangerous area, which increases time cost and operation complexity. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0043] refer to Figure 1 , Figure 1 The present invention provides a block diagram of the principles of a control system that links a fire and gas system with a video surveillance system.

[0044] like Figure 1 As shown, the control system of the fire and gas system linked with the video monitoring system includes: a fire and gas central control system and a video monitoring system.

[0045] Among them, the fire and gas central control system includes: multiple fire detection units installed on site, and multiple linkage channels corresponding to the multiple fire detection units; the video monitoring system includes: a control unit, multiple cameras installed on site, and a central display screen.

[0046] In an embodiment of the present invention, a plurality of fire detection units are used to detect a scene and output a fire detection signal when a fire signal is detected; a plurality of linkage channels are used to receive corresponding fire detection signals and trigger the generation of linkage signals according to the received fire detection signals and linkage rules; a control unit is connected to a plurality of cameras and is used to generate corresponding linkage control signals according to the received linkage signals, so as to control corresponding cameras among the plurality of cameras to rotate to a preset position, and receive video images captured by the cameras rotated to the preset position; any one or more of the plurality of cameras rotate to the preset position according to the linkage control signal output by the control unit, and after rotating to the preset position, the scene image is captured to obtain a video image; a central display screen is connected to the control unit and is used to receive the video image transmitted by the control unit and display the video image and perform a linkage pop-up display.

[0047] The present invention is based on the current Rockwell fire and gas central control system and CCTV system (video monitoring system), and realizes the linkage between the fire alarm of the fire and gas central control system and the video monitoring system, and realizes the emergency linkage of dangerous situations without affecting the original functions of each system. Through the present invention, the emergency response speed can be improved, and it has outstanding promotion performance and can be promoted to other offshore oil and gas field facilities.

[0048] Further, in the embodiment of the present invention, if Figure 1 As shown, the video monitoring system also includes: a plurality of signal converters arranged corresponding to the plurality of linkage channels.

[0049] The plurality of signal converters are respectively connected to the corresponding linkage channels, and are used to receive the corresponding linkage signals and convert the received linkage signals into video recognition signals, and send the video recognition signals to the control unit, so that the control unit generates corresponding linkage control signals based on the video recognition signals. By setting the signal converter, the linkage signals sent by the fire and gas central control system can be converted into signals that can be recognized by the video monitoring system.

[0050] It should be noted that, in the embodiment of the present invention, the number of linkage channels is determined based on the actual detection needs on site. For example, if the actual detection areas on site are 10, then correspondingly, there are 10 linkage channels, and if any one or more of the detectors in each detection area generates a fire detection signal, the linkage channels will trigger the generation of a corresponding linkage signal.

[0051] Optionally, in an embodiment of the present invention, each fire detection unit includes: a plurality of detectors (such as flame probes, smoke temperature probes, etc.); each linkage channel includes: a signal trigger module and a signal control module.

[0052] Among them, the signal trigger module is connected to multiple detectors, and is used to trigger the generation of a linkage signal when any one or more of the multiple detectors output a fire detection signal; the signal control module is connected to the signal trigger module, and is used to receive the linkage signal and send the linkage signal to the corresponding signal converter.

[0053] Optional, such as Figure 2 As shown, the signal trigger module includes: an OR gate and an SR trigger; multiple input ends of the OR gate are respectively connected to multiple detectors, the output end of the OR gate is connected to the signal receiving end of the SR trigger, and the output end of the SR trigger is connected to the signal control module.

[0054] Specifically, Figure 2 In the figure, “OR” is the OR gate, the input signal on its left is the fire detection signal generated by the detector, and the input signal on its right is the logic signal generated by the trigger. Figure 2 In the figure, "SR" is the SR trigger, SET1 is its signal receiving end, and RESE is its signal setting end. When the signal setting end receives the reset signal, the SR is reset. It should be noted that the priority of the linkage conditions on the left side of the OR gate is equal, that is, any condition can trigger the linkage output. Moreover, after the condition is triggered, the linkage signal will remain until the personnel confirms that the state can be reset and presses the reset button, and the linkage signal can return to normal, thereby ensuring the safety of signal release.

[0055] like Figure 3 As shown, FGS_DO_ON is a signal control module, which can realize locking, resetting, manual forcing, etc. of the linkage signal.

[0056] Specifically, Figure 2 As shown, when there is any one or more signal inputs on its left side, its output end outputs a high level "1". At this time, the output end of the SR trigger (i.e., the Q1 end) outputs a linkage signal, which is transmitted to the input end ("ITAG" end) of FGS_DO_ON. After the "ITAG" end of FGS_DO_ON receives the linkage signal, its output end "OUT" transmits the linkage signal to the corresponding signal converter.

[0057] Furthermore, in the embodiment of the present invention, each detector is also used to output a local fire alarm signal when a fire signal is detected. Specifically, when the flame detector or smoke temperature detector in the corresponding area of ​​the fire and gas central control system detects a fire signal, the alarm light, horn, etc. are immediately triggered to alert the on-site personnel to the fire situation.

[0058] Specifically, in the embodiment of the present invention, when the flame probe or smoke temperature probe in the corresponding area of ​​the fire and gas central control system detects a fire signal, the alarm light, horn, etc. are immediately triggered to remind the on-site personnel to pay attention to the fire situation, and according to the pre-designed linkage rules, the corresponding linkage signal is automatically sent to the video surveillance system;) After the signal converter receives the linkage signal sent by the FGS system (fire and gas central control system), it converts it into a signal that can be recognized by the video surveillance system, and sends it to the corresponding camera and video management server (control unit). After receiving the linkage signal, the video surveillance system immediately executes the corresponding action, such as driving the camera to rotate, switching the large screen image, etc. In this way, the automatic linkage between the fire alarm and the video surveillance system is realized.

[0059] Through this linkage mechanism, on the one hand, it can ensure that when a fire occurs, the video surveillance system can automatically switch to the relevant area for real-time monitoring and recording, thereby improving the efficiency of emergency response; on the other hand, it can also centrally display key information such as fire alarm information and on-site video footage, providing a basis for subsequent accident analysis and optimization of emergency plans.

[0060] refer to Figure 4 , Figure 4 The flowchart of the control method of the fire and gas system and the video monitoring system linkage provided by the present invention is shown in FIG. The control method of the fire and gas system and the video monitoring system linkage is applied to the control system of the fire and gas system and the video monitoring system linkage disclosed in the embodiment of the present invention.

[0061] Specifically, Figure 4 As shown, the control method of the fire and gas system and the video surveillance system linkage includes the following steps:

[0062] Step S401: The fire detection unit detects the scene and outputs a fire detection signal when a fire signal is detected.

[0063] Step S402: The fire and gas central control system receives a fire detection signal, and triggers a linkage signal according to the fire detection signal and the linkage rule.

[0064] Step S403: the video surveillance system receives the linkage signal, and outputs a display control signal and a linkage control signal based on the linkage rule.

[0065] Step S404: the camera rotates to a preset position according to the linkage control signal, and after rotating to the preset position, collects the scene image to obtain a video image.

[0066] Step S405: the central display screen displays the video image and performs a linked pop-up display according to the display control signal.

[0067] Furthermore, in the implementation of the present invention, the control method of the linkage between the fire and gas system and the video surveillance system also includes: determining whether a confirmation command input by the operator is received; if so, determining the fire on site and outputting an emergency response command.

[0068] Furthermore, in the implementation of the present invention, the control method for the linkage between the fire and gas system and the video surveillance system also includes: the fire detection unit also outputs a local alarm signal when a fire signal is detected.

[0069] Furthermore, in the implementation of the present invention, the control method for the linkage between the fire and gas system and the video surveillance system also includes: after the fire and gas central control system is triggered to generate a linkage signal, the linkage signal is maintained until it is restored when a reset signal is received.

[0070] Specifically, in an embodiment of the present invention, the fire and gas central control system and the video surveillance system are connected via a signal converter, and linkage rules are established to realize a linkage mechanism between two independent systems. Optionally, in an embodiment of the present invention, the linkage rules include: the fire detection signal generated by the area where the fire detection unit on site is located triggers the linkage of the camera in the area, and other device signals in the area do not participate in the linkage. When the fire and gas central control system detects a fire, it will immediately send a linkage signal to the video surveillance system, triggering the video surveillance system to perform real-time monitoring and recording. Each fire area corresponds to one linkage signal, ensuring the accuracy of the information. At the same time, the safety and reliability of the system are ensured through the designed linkage rules.

[0071] After receiving the linkage signal, the video surveillance system can automatically adjust the surveillance camera in the corresponding area to the preset position (preset location) according to the linkage information to ensure panoramic monitoring of the fire scene. At the same time, the video image of the fire area is displayed in full screen on the large screen (central display screen) of the command center to provide intuitive and timely information support for subsequent emergency response. This close collaborative feedback mechanism has greatly improved the efficiency and accuracy of the entire emergency response process.

[0072] Compared with the traditional independent operation mode, the present invention can greatly improve the overall level of fire emergency response. First, the linkage mechanism can quickly obtain first-hand information on the fire scene and provide timely support for emergency command; second, the panoramic monitoring and large-screen display functions can intuitively present the fire situation and improve the accuracy of emergency response; third, the SIL3 level of safety protection ensures the high reliability of the system in emergency situations. In general, the present invention is of great significance in improving fire emergency response capabilities and ensuring the safety of personnel and property.
