Description

Technical Field

[0001] The utility model relates to an automatic reading device for local instrument data in a ship power engine room, belonging to the technical field of local instrument data reading. Background Art

[0002] The ship power equipment is a very large functional equipment, which is distributed in several cabins. Each cabin is composed of boilers, main engines and corresponding auxiliary machines. Each independent unit corresponds to a set of measurement and control systems to realize monitoring, control, alarm, interlocking and protection functions for boilers, main engines and auxiliary machines. The hardware basis for the realization of these functions is measurement equipment, including hundreds of temperature measurement equipment, pressure measurement equipment, flow measurement equipment, speed measurement equipment and valve opening measurement equipment.

[0003] Most of the measurement point data of the measurement control system are collected by on-site measurement equipment such as sensors or transmitters, and then the collected analog signals are uploaded to the control room and displayed in the human-machine interface or secondary instruments. For some important measurement points, it is also necessary to display instruments on-site in the cabin for operators to compare and reference the remote transmission signals and local signals. The accuracy of the remote transmission of the measurement point signal and the display of the local information plays a decisive role in the ship power plant monitoring system.

[0004] For measuring points in the engine room that require on-site secondary instrument displays, these usually correspond to important measurement parameters. In order to monitor similar important parameters among many measuring points, they will be highlighted in the form of instrument displays. At the same time, in order to avoid signal abnormalities caused by problems with the equipment itself and to improve the reliability of the power monitoring system, dual-channel measuring equipment is usually placed at important measuring points, or two identical measuring devices are placed to generate two identical signal sources. One of the signal sources is transmitted remotely to the power monitoring platform in the control room, and the other signal source is sent to the on-site instrument in the engine room for secondary display. If the measured value at a certain point on the power monitoring platform is abnormal, the cause of the abnormality can be found by comparing the on-site display value. Therefore, the dual-channel signal source can provide a basis for troubleshooting.

[0005] When necessary, operators need to enter the engine room to view the display data of the local secondary instruments. Due to the small space inside the engine room, poor lighting conditions, and different power units distributed in different engine rooms, it is not easy for operators to view the display data.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0030] Specific implementation method 1. Combination Figure 1 As shown, the utility model provides a device for automatically reading data of local instruments in a ship power engine room, comprising a plurality of sets of local instrument data acquisition devices, a plurality of engine room image transmission radio stations 200, a control room image transmission radio station 300 and an image processing module 400.

[0031] A set of local instrument data acquisition device and a cabin image transmission radio 200 are arranged in each cabin; each set of local instrument data acquisition device includes a camera 110 and multiple searchlights 120, the multiple searchlights 120 are used to provide lighting for all target local instrument panels in the cabin, and the camera 110 is used to obtain display data images of all target local instrument panels; the image data output end of the camera 110 is connected to the image data input end of the cabin image transmission radio 200; the cabin image transmission radio 200 transmits the received display data image to the control room image transmission radio 300, and the image processing module 400 performs data recognition on the display data image transmitted by the control room image transmission radio 300 to obtain the display data of the target local instrument panel.

[0032] In this embodiment, the automatic reading device includes a cabin part and a control room part. According to the centralized position of the on-site instruments inside the cabin, a camera and a searchlight can be set at a suitable position, so that the camera can clearly capture the on-site instrument panel within the visible range with the help of the searchlight. An image transmission radio is respectively configured in the cabin and the control room, the camera in the cabin is connected to the image transmission radio, and the image transmission radio in the control room is connected to the image processing module 400. The image processing module 400 can be implemented by a computer. The image transmission radio in the control room is connected to a computer. The image captured by the camera is uploaded to the image transmission radio in the control room through the image transmission radio, and the image processing module 400 in the control room can restore the data in the image. The image processing module 400 can use existing image processing methods to identify the data displayed on the on-site instrument panel.

[0033] The image processing module 400 can decompress and extract image sample frames for image processing, and use relevant image processing methods to segment the secondary instrument panels in the image, and recognize the indication of each instrument panel in real time. The recognition result can be communicated to the power system measurement and control platform, and directly compared with the remote measurement data of the corresponding measurement point in the platform. When the difference exceeds a reasonable range, it can be preliminarily determined that the measurement point has a fault and the measurement data is already in an unreliable state. At this time, an alarm can be issued to prompt corresponding processing.

[0034] In this implementation, the camera and the cabin image transmission radio are interconnected via a signal interface, and the cabin image transmission radio and the control room image transmission radio achieve wireless real-time transmission of images of on-site instrument areas in all cabins.

[0035] Camera and searchlight location selection:

[0036] Since the cabin is dark, the camera needs to be supplemented with lighting to obtain good video quality. Generally speaking, in order to facilitate inspection and maintenance, the dashboards are closely and neatly placed in one place. When the camera is used to obtain the image of the dashboard, it must cover all the dashboards, and the clarity of each dashboard must be appropriate. Therefore, uniform lighting is very important for the quality of the video image.

[0037] As an example, combining Figure 2 As shown, each set of local instrument data acquisition device includes four searchlights 120, and the four searchlights 120 are installed correspondingly at the four corner points of the smallest square area formed by the distribution of all target local instrument panels in the cabin; the smallest square area where the panels of all target local instrument panels are located is a plane perpendicular to the ground, and the camera 110 is installed by adjusting the bracket directly in front of the center point of the smallest square area, so that the camera 110 can directly obtain a clear image directly in front of the target local instrument panel.

[0038] This implementation provides lighting conditions for all instrument panels from four angles. First, a minimum square area is drawn to envelop all instrument panels. Searchlights are located at the four corners of the square area to ensure that all instrument panels receive uniform light illumination. Figure 2 Now select the center height of the square area and install the camera at the selected height facing the instrument panel cluster to ensure that the image field of view recorded by the camera includes all the instrument panels and is displayed with the maximum area efficiency. Figure 2 In the figure, A represents the center point of the smallest square area, and B represents the target local instrument panel.

[0039] The following introduces the fixed structure of the camera:

[0040] The camera is installed at a high position facing the center of the instrument panel cluster. Since it works inside the cabin, the camera's fixing structure needs to take into account the vibration of the hull, as well as the fine-tuning of the camera height and lens angle. This embodiment proposes a mechanical adjustment bracket for installing the camera.

[0041] Further, combined with Figure 3 As shown, the adjustment bracket includes a shock-absorbing base 510, a retractable support rod 520 and a support platform 530. The shock-absorbing base 510 is fixed to the ground, the retractable support rod 520 is connected to the shock-absorbing base 510, and the end of the retractable support rod 520 is connected to the support platform 530. The support position of the adjustment bracket is made so that the camera is directly in front of the center point of the minimum square area.

[0042] The adjustment bracket is divided into two parts, a base and a retractable support rod. The base provides shock-absorbing support, and the retractable support rod is used to support the support platform 530 and then fix the camera.

[0043] In this embodiment, combined with Figures 4 to 7 As shown, the support section of the shock-absorbing base 510 has an outer cylindrical ring structure, and the telescopic support rod 520 has an inner cylindrical ring structure. Both the inner cylindrical ring structure and the outer cylindrical ring structure have bolt holes arranged along the height direction. The inner cylindrical ring structure and the outer cylindrical ring structure are fixedly connected by bolts corresponding to the selected bolt holes.

[0044] The bolt holes at each height on the inner cylindrical ring structure and the outer cylindrical ring structure include four bolt holes evenly distributed along the circumferential direction. The outer diameter of the inner cylindrical ring structure is equal to the inner diameter of the outer cylindrical ring structure, so that the two can match and fix each other. After the relative position is fixed by selecting the bolt holes, the height and angle of the camera can be adjusted. Figure 3 The left side of the figure shows the inner cylindrical ring structure, and the right side shows the outer cylindrical ring structure. The red mark in the figure shows the location of the bolt hole.

[0045] As an example, combining Figure 3 As shown, a triangular support is formed between the support platform 530 and the retractable support rod 520 through a support arm. The support arm can strengthen and adjust the stability of the bracket and provide stable support for the camera.

[0046] Combination Figure 6 As shown, the bolt holes arranged along the height direction on the inner cylindrical ring structure or the outer cylindrical ring structure are staggered in sequence along the circumferential direction at intervals of a preset angle.

[0047] Combination Figure 5As shown, the bolt holes of the outer cylindrical ring structure are in the same direction as the axis of the camera stand in the horizontal direction, and the longitudinal direction is perpendicular to the horizontal direction. The overlapping and matching parts of the inner cylindrical ring structure and the outer cylindrical ring structure can be divided into 10 segments with the same scale, and threaded holes are set between the segments. Four threaded holes are set on each plane. The camera is fixed mainly by using bolts through the 8 threaded holes corresponding to the inner and outer cylindrical ring structures. The positions of the threaded holes of the outer cylindrical ring structure are set as shown in the figure. Figure 5 As shown on the right. The position settings of the threaded holes of the cylindrical ring structure are as follows Figure 5 Shown on the left.

[0048] In this implementation, the preset angle is 18 degrees.

[0049] The orientation diagram of the threaded hole of the inner cylindrical ring structure is as follows Figure 6 As shown, Figure 6 The upper part corresponds to Figure 4 The position of the threaded hole on the uniform scale in the upper half of the middle position of the inner cylindrical ring structure on the left side is Figure 5 The left horizontal and vertical axes are rotated counterclockwise at 4 angles. The angle of continuous rotation is 18 degrees. Figure 6 The lower part corresponds to Figure 4 The position of the threaded hole on the uniform scale in the lower half of the middle position of the inner cylindrical ring structure on the left side is Figure 5 The left horizontal and vertical axis is rotated clockwise at 4 angles. The angle of continuous rotation is 18 degrees.

[0050] The threaded holes of the inner cylindrical ring structure can fine-tune the position of the camera stand, and the threaded holes of the outer cylindrical ring structure can fine-tune the height of the camera stand. The two can be combined to adjust the position angle and height of the camera stand. After the threaded holes of the inner cylindrical ring structure and the outer cylindrical ring structure are aligned, they are fixed by 4 long bolts. The matching fixation diagram is shown in the figure. Figure 7 shown.

[0051] The utility model can realize the automatic real-time reading of the secondary instrument panel indications on site in the ship power engine room, which greatly saves the physical labor of the operator and the energy of going to the engine room with harsh conditions for operation under unnecessary conditions.
