Description

Technical Field

[0001] The present application relates to the technical field of hydrogenation equipment, and in particular to a data security protection device for a hydrogenation station control system. Background Art

[0002] In a hydrogen refueling station, it is often necessary to set up a station control system to control various equipment and pipelines in the entire hydrogen refueling station, and also to monitor the entire hydrogen refueling station.

[0003] The station control system is mainly composed of a control system, a detection and alarm system, and an emergency shutoff system. The control system is used to control the operation of various equipment in the hydrogenation station, including hydrogenators, purge devices, chillers, gas unloading columns, chillers, etc., and is mainly used to realize the functions of the hydrogenation station. The detection and alarm system is mainly used to detect hydrogenators, pipelines, and the on-site environment of the hydrogenation station. It mainly detects the status of each device, whether hydrogen is leaking, whether there is a flame, etc., and promptly issues an alarm when a problem is detected. The emergency shutoff system is mainly used to promptly cut off the power supply of the main equipment and close the valves of important pipelines when an accident occurs or the detection and alarm system is in an alarm state. In addition, the station control system also includes a data acquisition system, which is mainly used to collect and display data from various equipment and instruments in the hydrogenation station.

[0004] With regard to the above-mentioned related technologies, the setting of the station control system can improve the automation level of the hydrogen refueling station, reduce the inspection pressure of the staff, and improve the working safety of the hydrogen refueling station. However, when an explosion occurs at a hydrogen refueling station due to an unexpected situation, it is often necessary to find the cause of the explosion. At this time, it is necessary to read the data of the controller in the station control system. The controller in the station control system is easily damaged by the explosion or vibration, and thus the data before the explosion cannot be read, and the cause of the explosion cannot be understood. Summary of the invention

[0005] The present application provides a data security protection device for a station control system of a hydrogen refueling station, the purpose of which is to print and store the detection data in time before the station control system is exploded. At this time, even if an explosion occurs, it is difficult to damage the printed paper data, thereby facilitating the reading of the data of the station control system.

[0006] The present application provides a data security protection device for a hydrogen refueling station control system, which adopts the following technical solution: a data security protection device for a hydrogen refueling station control system, comprising a controller; A detection mechanism, used to detect the working status of each device and the hydrogen concentration, and transmit the detection data to the controller; A control valve group, used to control the on-off of each pipeline, the control valve group is electrically connected to the controller, and the controller controls the control valve group to cut off or open the corresponding pipeline according to the detection data of the detection mechanism; A printer, the printer is electrically connected to the controller, and the controller transmits the detection data of the detection mechanism to the printer, and the printer prints the detection data; A control cabinet, wherein the controller and the printer are both installed in the control cabinet.

[0007] By adopting the above technical solution, the detection mechanism is used to detect the status of each device, the status of each pipeline and the hydrogen concentration of the hydrogen station environment, and the control valve group is used to control the opening and closing of each pipeline.

[0008] Therefore, the detection data is transmitted to the controller in real time through the detection mechanism, and the controller can monitor the status of the entire hydrogen refueling station in real time. When the detection data transmitted to the controller by the detection mechanism does not match the preset value of the controller and a large error occurs, the controller can cut off all pipelines in time by controlling the control valve group to ensure that hydrogen cannot flow, thereby ensuring the safety of the hydrogen refueling station.

[0009] As for the setting of the printer, the controller can store the detection data of the detection mechanism, and when the detection data is abnormal, the controller will transmit the abnormal data and the corresponding time to the printer, and the printer will print the data on paper for preservation; and when the detection data is abnormal, the detection mechanism will work in real time, and when the detection data changes, the controller will transmit the changed data to the printer, and the printer will print the data record; and when the detection data is in an abnormal state, the host computer will make data changes or operation records to the controller, and the controller will transmit the modified data as well as the operation time and operation host computer information to the printer, and the printer will print the corresponding data record.

[0010] Since the printer and controller are both installed in the control cabinet, even if an explosion occurs at the hydrogen refueling station and damages the controller, the control cabinet can protect the paper documents and prevent them from being burned. The data before the explosion can also be read through the retained paper documents, so the cause of the explosion can be understood.

[0011] Optionally, a storage box is further provided in the control cabinet, the storage box is provided on one side of the printer, and a collecting hole is opened on the side of the storage box facing the printer, the collecting hole is connected to the storage box, and the collecting hole is connected to the paper outlet of the printer.

[0012] By adopting the above technical solution, a storage box is arranged in the control cabinet, and a collecting hole is opened on the storage box, and the collecting hole is connected to the paper outlet of the printer. The paper printed by the printer will be directly sent into the collecting hole, so that the storage box can protect the printed paper.

[0013] Optionally, a closing plate and a closing seat are provided on a side of the storage box facing the printer. The closing plate is slidably connected to the storage box, and the sliding direction of the closing plate is perpendicular to the spacing direction between the storage box and the printer; The closing seat is connected to the storage box, the closing seat is arranged opposite to the closing plate along the sliding direction of the closing plate, and the collecting hole is located between the closing seat and the closing plate; The closing plate is provided with a closing driving member for driving the closing plate to slide; When the closing plate slides to abut against the closing seat, the closing plate closes the collecting hole.

[0014] By adopting the above technical solution, a closing plate and a closing seat are provided on one side of the storage box where the collection hole is opened, the closing plate is slidably connected to the storage box, and the closing seat is connected to the storage box, and a closing drive member is provided on the closing plate. Driven by the closing drive member, the closing plate can slide until it contacts the storage box, and when the closing plate contacts the storage box, the closing plate can close the collection hole.

[0015] Therefore, after the storage box stores the printed paper, the collecting hole can be closed by the closing plate, thereby improving the protective effect of the storage box on the printed paper.

[0016] Optionally, the closed driving member includes a first passive magnet and a first electromagnet, the first passive magnet is arranged on a side of the closed plate facing the closed seat, the first electromagnet is arranged on a side of the closed seat facing the closed plate, and the first passive magnet is arranged opposite to the first electromagnet along the sliding direction of the closed plate.

[0017] By adopting the above technical solution, since the first electromagnet and the first passive magnet are arranged opposite to each other along the sliding direction of the closing plate, when it is necessary to open the collecting hole, the magnetic poles of the first electromagnet and the first passive magnet on the opposite side are the same, and the closing plate moves away from the closing seat to open the collecting hole; and when it is necessary to close the collecting hole, the first electromagnet is powered off or the magnetic pole of the first electromagnet is switched, and the closing plate slides toward the closing seat until the lower side of the closing plate contacts the closing seat, thereby realizing the closure of the collecting hole.

[0018] Therefore, the closing plate can be driven by the cooperation of the first electromagnet and the first passive magnet.

[0019] Optionally, a cutting knife is provided on a side of the closing plate facing the closing seat, and a cutting groove is provided on a side of the closing seat facing the closing plate; When the closing plate abuts against the closing seat, the cutting knife is inserted into the knife groove.

[0020] By adopting the above technical solution, the cutter is arranged so that when the closing plate slides to abut against the closing seat, the cutter can cut the paper entering the collection hole, thereby preventing the storage box from being separated from the side wall of the control cabinet when an explosion occurs, causing the printing paper in the storage box to be pulled out from the collection hole. The arrangement of the knife groove facilitates the cutter to cut the paper, while preventing the cutter from directly impacting the closing seat and causing the cutter to collapse.

[0021] Optionally, an active roller and a driven roller are provided on the inner wall of the collecting hole, the active roller is arranged in parallel with the driven roller, both ends of the active roller and the driven roller are rotatably connected to the inner wall of the collecting hole, and the active roller is coaxially connected to a conveying drive source.

[0022] By adopting the above technical solution, the active roller and the driven roller are arranged in coordination, and the active roller is coaxially connected with a conveying drive source. When the paper is fed from the collecting hole into between the active roller and the driven roller, the conveying drive source drives the active roller to rotate, and the active roller and the driven roller cooperate to convey the paper into the storage box, ensuring that the paper with printed data can be stored in the storage box.

[0023] Optionally, the active roller is slidably connected to the inner wall of the collecting hole along the spacing direction between the active roller and the driven roller, and the conveying drive source is slidably connected to the inner wall of the collecting hole; The driven roller is slidably connected to the inner wall of the collecting hole along the spacing direction between the active roller and the driven roller; A hidden driving member for driving the active roller and the driven roller to move closer to or farther from each other is arranged between the active roller and the driven roller.

[0024] By adopting the above technical solution, since both the active roller and the driven roller are slidably connected to the inner wall of the collecting hole, the hidden driving member can control the active roller and the driven roller to move closer to or away from each other. Therefore, when the paper is just fed in, the active roller and the driven roller move away from each other, which facilitates the feeding of the paper between the active roller and the driven roller. When the paper moves between the active roller and the driven roller, the active roller and the driven roller move closer to each other, which can clamp the paper. When the active roller rotates, the paper can be fed.

[0025] Optionally, the hidden driving member includes a mounting seat, the mounting seat is arranged on the inner side wall of the collecting hole, and the mounting seat is located between the driven roller and the active roller; A first fixed magnet is disposed on a side of the mounting seat facing the active roller, and a second fixed magnet is disposed on a side of the mounting seat facing the driven roller; An active electromagnet is provided on the side of the active roller facing the first fixed magnet; A driven electromagnet is provided on a side of the driven roller facing the second fixed magnet.

[0026] By adopting the above technical solution, the hidden driving component includes a mounting seat, and the mounting seat is located between the active roller and the driven roller, and a first fixed magnet is arranged on the side of the mounting seat facing the active roller, and an active electromagnet is arranged on the side of the active roller facing the mounting seat, so when the active electromagnet is energized, the first fixed magnet and the active electromagnet are attracted, and the active roller can move toward the mounting seat at this time; the mounting seat faces the second fixed magnet of the driven roller, and a driven electromagnet is arranged on the side of the driven roller facing the mounting seat, so when the driven electromagnet is energized, the driven electromagnet and the second fixed magnet are attracted, and the driven roller can move toward the mounting seat at this time.

[0027] Therefore, through the cooperation of the active electromagnet and the driven electromagnet, the driven rollers can move closer to or farther from each other.

[0028] Optionally, a protection cabinet is further included, wherein the control cabinet is installed in the protection cabinet, the side walls of the control cabinet are each provided with a fixing plate, and a plurality of elastic shock absorbing parts are provided between the fixing plate and the corresponding inner side walls of the protection cabinet.

[0029] By adopting the above technical solution, the fixed plate and the elastic shock-absorbing member are arranged in coordination, and when an explosion occurs, the control cabinet can be shock-absorbed and buffered, thereby increasing the safety of the controller in the control cabinet.

[0030] Optionally, a sliding column is provided between the fixed plate and the inner side wall corresponding to the protective cabinet, a sliding sleeve is sleeved on the outer side of the sliding column, the sliding column is slidably connected with the inner wall of the sliding sleeve along its own axial direction, one end of the sliding column is in contact with the fixed plate, and one end of the sliding sleeve is connected with the inner side wall corresponding to the protective cabinet; The end of the sliding column away from the fixed plate is rotatably connected to the first rod, the end of the first rod away from the sliding column is rotatably connected to the second rod, and the end of the second rod away from the first rod is rotatably connected to the inner wall corresponding to the protective cabinet; A driving rod is provided at the connection between the first rod and the second rod. The driving rod is rotationally connected to the first rod and the second rod. The axial direction of the driving rod is perpendicular to the axial direction of the sliding column, and the driving rod is coaxially connected to a lifting driving source that drives the driving rod to move along its own length direction.

[0031] By adopting the above technical solution, due to the coordinated arrangement of the first rod, the second rod, the driving rod, the sliding column and the sliding sleeve, when the driving rod moves along its own length direction, it can drive the first rod and the second rod to move, and when the first rod and the second rod are collinear, the first rod and the second rod cooperate to push out the sliding column, and the sliding column can contact the fixed plate, thereby realizing a rigid connection between the sliding column and the fixed plate. When the driving rod continues to move along its own length direction, when the first rod and the second rod move from collinearity to non-collinearity, the sliding column will retract into the sliding sleeve, so the sliding column is separated from the fixed plate, so the rigid connection between the sliding column and the fixed plate can be released.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application sets a printer in the control cabinet, and the printer is electrically connected to the controller. Therefore, even if an explosion occurs in the hydrogen station and damages the controller, the control cabinet can protect the paper documents and prevent them from being burned.

When the detection data of the detection mechanism 2 does not match the preset value in the controller 1 and a large error occurs, the controller 1 can cut off all pipelines in time by controlling the control valve group 3 to ensure that hydrogen cannot flow, thereby ensuring the safety of the hydrogen refueling station.

[0048] At the same time, the controller 1 will transmit the detection data to the host computer in real time, and draw real-time trend curves and historical trend curves based on the detection data to facilitate real-time monitoring by the staff.

[0049] Reference Figure 1 The station control system also includes an alarm mechanism 5, which is electrically connected to the controller 1. The alarm mechanism 5 uses an audible and visual alarm.

[0070] Therefore, when the active electromagnet 6564 and the driven electromagnet 6565 are both energized, the first slide 654 and the second slide 655 move toward each other in the vertical direction, so that when the paper delivered by the printer 4 is delivered between the active roller 651 and the driven roller 652, the active roller 651, driven by the conveying driving source 653, can deliver the paper into the collecting hole 631. When the active electromagnet 6564 and the driven electromagnet 6565 are energized in the opposite direction, the first slide 654 and the second slide 655 move away from each other in the vertical direction, and the paper is not delivered at this time, but it is convenient for the paper to move between the driven roller 652 and the active roller 651.

[0071] Reference Figure 7 and Figure 8 The station control system further includes a protection cabinet 7, and a protection door 71 is provided on one side of the opening of the protection cabinet 7. The protection door 71 is rotatably connected to the protection cabinet 7, so that the protection door 71 can open or close the opening of the protection cabinet 7. The control cabinet 6 is fixed to the bottom wall of the protection cabinet 7 by bolts, and the opening of the control cabinet 6 faces one side of the protection door 71. Therefore, the protection cabinet 7 can provide a second level of protection for the control cabinet 6.

[0072] Reference Figure 8 and Fig. 9A fixing assembly 72 is arranged between the inner wall of the protection cabinet 7 and the outer wall corresponding to the control cabinet 6. The fixing assembly 72 includes a fixing plate 721. The fixing plate 721 contacts the corresponding side wall of the control cabinet 6. A plurality of elastic damping members 722 are arranged between the fixing plate 721 and the corresponding inner wall of the protection cabinet 7. The elastic damping members 722 include a spring and a damper, and the spring is sleeved on the outer side of the elastic damper. The two ends of the elastic damping members 722 are respectively connected to the fixing plate 721 and the corresponding inner wall of the protection cabinet 7. Therefore, the matching arrangement of the fixing plate 721 and the elastic damping members 722 can buffer the internal control cabinet 6 when subjected to an explosion impact, thereby ensuring the safety of the controller 1 inside the explosion control cabinet 6 as much as possible.

[0073] Reference Figure 8 and Fig. 9 A sliding column 723 is provided between the fixed plate 721 and the inner wall corresponding to the protective cabinet 7. The axial direction of the sliding column 723 is arranged along the spacing direction between the fixed plate 721 and the inner wall corresponding to the protective cabinet 7. A sliding sleeve 724 is sleeved on the outer side of the sliding column 723. One end of the sliding sleeve 724 is connected to the inner wall corresponding to the protective cabinet 7. The other end of the sliding sleeve 724 is spaced apart from the corresponding fixed plate 721. The sliding column 723 is slidably connected to the inner wall of the sliding sleeve 724 along its own axial direction. A resistance driving member 725 is provided between the sliding column 723 and the inner wall corresponding to the protective cabinet 7. The driving direction of the resistance driving member 725 is arranged along the axial direction of the sliding column 723.

[0074] When the sliding column 723 contacts the corresponding fixed plate 721, there is a rigid support between the protection cabinet 7 and the control cabinet 6, which can improve the stability of the fixation of the control cabinet 6 during normal operation; and when a possible explosion is detected, the sliding column 723 is retracted into the sliding sleeve 724, so that the sliding column 723 is separated from the fixed plate 721, and the elastic shock-absorbing member 722 can provide shock-absorbing support for the control cabinet 6.

[0075] Reference Figure 8 and Fig. 9The abutment driving member 725 includes a rigid rod 7251, which is arranged one-to-one with the sliding column 723. The rigid rod 7251 includes a first rod 7252 and a second rod 7253, which are both located in the corresponding sliding sleeve 724. One end of the first rod 7252 is slidably connected to the inner wall corresponding to the protective cabinet 7, and the other end of the first rod 7252 is rotatably connected to the second rod 7253. One end of the second rod 7253 away from the first rod 7252 is rotatably connected to the sliding column 723. A long groove 7241 is provided on the upper side of the sliding sleeve 724, and the long groove 7241 passes through the sliding sleeve 724 in the vertical direction. The abutment driving member 725 also includes a driving rod 7254, which is arranged in the vertical direction. The lower end of the driving rod 7254 is connected to a lifting driving source 7255, which is a linear push rod or a cylinder. The first rod 7252 and the second rod 7253 are both rotatably connected to the driving rod 7254 at their joints. The driving rod 7254 is plugged into the long slot 7241, and the driving rod 7254 is slidably connected to the inner wall of the long slot 7241 in the vertical direction. The first rod 7252 and the second rod 7253 can both be plugged into the long slot 7241, and the first rod 7252 and the second rod 7253 can both be slidably connected to the inner wall of the long slot 7241.

[0076] Therefore, when the driving rod 7254 moves in the vertical direction, it can drive the first rod 7252 and the second rod 7253 to move, and when the first rod 7252 and the second rod 7253 are collinear, the rigid rod 7251 can push out the sliding column 723, and the sliding column 723 can contact the fixed plate 721, thereby realizing the rigid connection between the sliding column 723 and the fixed plate 721. When the first rod 7252 and the second rod 7253 move from collinearity to non-collinearity, the sliding column 723 retracts into the sliding sleeve 724, thereby releasing the rigid connection between the sliding column 723 and the fixed plate 721.

[0077] Reference Figure 8 and Fig. 9 A long sliding hole 7256 is penetrated through the first rod 7252, and the length direction of the long sliding hole 7256 is set along the length direction of the first rod 7252. A rotating shaft 7257 is set at one end of the second rod 7253 facing the first rod 7252. The driving rod 7254 is plugged into and rotatably connected with the rotating shaft 7257. The rotating shaft 7257 is plugged into and rotatably connected with the long sliding hole 7256, and the rotating shaft 7257 is slidably connected with the inner wall of the long sliding hole 7256 along the length direction of the long sliding hole 7256.

[0078] When the driving rod 7254 drives the first rod 7252 and the second rod 7253 to rotate from being collinear to being non-collinear, the driving rod 7254 will be driven by the first rod 7252 to move toward the corresponding inner wall direction of the protective cabinet 7. Therefore, in order to eliminate the force applied to the driving rod 7254, the setting of the rotating shaft 7257 and the long sliding hole 7256 enables the first rod 7252, the second rod 7253 and the driving rod 7254 to be rotatably connected. At the same time, the rotating shaft 7257 moves along the length direction of the long sliding hole 7256, which can eliminate the force between the first rod 7252 and the driving rod 7254.

[0079] The implementation principle of the embodiment of the present application is: the detection mechanism 2 monitors the status of various equipment and various pipelines in the hydrogen refueling station. The detection mechanism 2 also monitors the hydrogen concentration and flame in the environment of the hydrogen refueling station in real time, and transmits the detection data to the controller 1 in real time. The controller 1 transmits the detection data to the host computer for real-time drawing of trend charts, which is convenient for staff to monitor the status of the hydrogen refueling station.

[0080] In addition, the detection data will be compared with the preset value of the controller 1. When the error between the detection data and the preset value exceeds the maximum limit, the controller 1 controls the control valve group 3, cuts off the corresponding pipeline, and shuts down the corresponding equipment. At this time, the controller 1 transmits the abnormal detection data to the printer 4, and the printer 4 sends the paper of the print data into the storage box 63; during this process, whenever there is an abnormal change in the detection data, the controller 1 will send the corresponding abnormal data and time data to the printer 4, and print the data; during this process, the staff changes the data of the controller 1 through the host computer, and the controller 1 will send the modified data, time and information of the host computer to the printer 4, and the data will be printed.

[0081] In addition, the controller 1 will also activate the alarm mechanism 5 to remind the staff.

[0082] When an abnormality is detected in the detection data, the sliding column 723 retracts into the sliding sleeve 724 to prepare for vibration reduction and buffering of the control cabinet 6 .

[0083] When an explosion is detected, the conveying roller set 65 will quickly feed the paper into the storage box 63, and then the closing plate 643 will cut off the excess paper.

[0084] Therefore, the above-mentioned station control system can automatically control the entire hydrogen refueling station and automatically detect it at the same time. When the detection data is abnormal, the abnormal data will be printed and retained, and within the time from the abnormal detection data to the recovery of normal or between the abnormal detection data and the explosion accident, all the operation processes of the staff and the detection data of the detection mechanism 2 will be recorded on paper, so as to facilitate the later determination of the cause of the accident.

[0085] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
