Description

Technical Field

[0001] The utility model relates to the field of radio orientation (IPC classification G01S17 / 00), in particular to a monitoring device. Background Art

[0002] Geological disasters refer to geological actions or phenomena caused by natural or human factors that cause loss of human life and property and damage to the environment. There is no early warning for geological disasters, and we can only monitor the site where geological disasters may occur. After a geological disaster occurs, we can quickly obtain geological disaster information through monitoring devices to facilitate rescue.

[0003] At present, the monitoring of geological disasters usually uses radar monitoring devices to monitor the current environment. When a geological disaster occurs, an alarm message is issued to remind geological disaster rescue personnel to implement rescue. However, radar can only monitor whether the natural slopes or large buildings on the scene are deformed through electromagnetic waves to know whether a geological disaster has occurred on the scene, and then issue an alarm message. However, the radar monitoring device cannot directly feedback the actual image information of the geological disaster site, so that rescue personnel cannot know the actual situation of the geological disaster site and prepare corresponding rescue tools. At the same time, the radar monitoring device may misjudge the actual geological conditions on the scene and issue an erroneous alarm message, so that rescue personnel go to the site where no geological disaster has occurred, thereby causing a waste of human resources.

[0004] In order to solve the above problems, in the related technology, the monitoring device is improved, and a camera is added on the basis of the original radar. The radar and the camera are used for joint monitoring. The camera can capture the actual image of the geological disaster site and feed the actual image back to the rescue personnel, thereby improving the monitoring accuracy of the monitoring system. In this scheme, in order to expand the monitoring range of the radar and the camera, it is necessary to design a set of motion drive mechanisms for the radar and the camera respectively, so as to adjust the spatial position of the radar and the camera and expand the monitoring range of both. However, designing motion drive mechanisms for the radar and the camera separately not only increases the overall size of the monitoring device, requiring a larger installation space, but also increases the cost of components, which is not convenient for the market promotion of the monitoring device.

[0005] Therefore, there is an urgent need for a monitoring device to solve the above problems. Utility Model Content

[0006] One purpose of the utility model is to provide a monitoring device to reduce the size of the entire monitoring device and reduce the cost of the entire device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0008] A monitoring device, comprising:

[0009] case;

[0010] A radar assembly is installed in the housing;

[0011] A camera is installed in the housing;

[0012] The motion driving mechanism has an output end fixedly connected to the housing and is used to drive the housing to move.

[0013] As an alternative to the detection device, the shell has a first shell and a second shell, the second shell is snapped together with the first shell to form a first accommodating cavity; the radar assembly includes a radar antenna, and the second shell has a notch at a position corresponding to the radar antenna.

[0014] As an alternative to the detection device, the radar assembly further includes a wave-transmitting plate, which is located in the first accommodating cavity and seals and covers the gap.

[0015] As an alternative to the detection device, a first sealing strip is provided at a connection portion between the first housing and the second housing.

[0016] As an alternative to the detection device, the camera includes a lens, and the shell further includes a third shell. The first shell and the third shell are snapped together to form a second accommodating cavity. Both the first shell and the second shell have a through hole for the lens to pass through.

[0017] As an alternative solution of the detection device, a second sealing strip is provided between the outer wall of the lens and the inner wall of the through hole.

[0018] As an alternative solution to the detection device, the shell further includes a back plate, the back plate is fixedly connected to the first shell, and the back plate is fixedly connected to the output end of the motion drive mechanism.

[0019] As an alternative to the detection device, the monitoring device also includes a receiving component for receiving communication information sent by the radar component and the camera. The receiving component is fixed to the output end of the motion drive mechanism and is located in the second accommodating cavity.

[0020] As an alternative to the detection device, the receiving component has a positioning module, which can obtain the position of the monitoring device.

[0021] As an alternative to the detection device, the motion drive mechanism includes a first drive member, a second drive member and a fixed table. The output end of the first drive member is connected to the second drive member and is used to drive the second drive member to rotate around the first axis. The output end of the second drive member is connected to the fixed table and is used to drive the fixed table to swing around the second axis. The fixed table is fixedly connected to the shell as the output end of the motion drive mechanism.

[0022] The beneficial effect of the monitoring device provided by the utility model is that by integrating the radar component and the camera inside the shell, and installing the shell on the output end of the motion drive mechanism, a set of motion drive mechanism can be used to simultaneously drive the radar component and the camera to move simultaneously, thereby expanding the monitoring range of the radar component and the camera while reducing the overall volume of the monitoring device and reducing the installation space required for installing the monitoring device.

[0038] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of the present invention, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] Figure 1The structure diagram of the monitoring device provided by the utility model is shown. Figure 2 The following is a schematic diagram of the monitoring device provided by the utility model. Figure 2 Combination Figure 1 As shown, the monitoring device includes a housing 1, a radar assembly 2, a camera 3 and a motion drive mechanism 4. The radar assembly 2 and the camera 3 are both installed in the housing 1. The housing 1 is fixedly connected to the output end of the motion drive mechanism 4, and the motion drive mechanism 4 drives the housing 1 to move. By integrating the radar assembly 2 and the camera 3 inside the housing 1 and making the motion drive mechanism 4 drive the housing 1 to move, the radar assembly 2 and the camera 3 can be driven to move simultaneously by a set of motion drive mechanisms 4, which not only expands the monitoring range of the radar assembly 2 and the camera 3, but also reduces the overall volume of the monitoring device and reduces the installation space required for installing the monitoring device.

[0043] like Figure 2 As shown, the housing 1 has a first housing 11 and a second housing 12, which are buckled together to form a first accommodating cavity. A first sealing strip 101 is provided at the connection portion between the first housing 11 and the second housing 12. The radar assembly 2 is installed in the first accommodating cavity to prevent acid rain or dust from directly falling on the radar antenna 21 and corroding or wearing the radar antenna 21 to normally transmit and receive electromagnetic waves. In addition, the radar assembly 2 has a radar antenna 21, and the second housing 12 has a notch 121 at a position corresponding to the radar antenna 21. By directly installing the radar assembly 2 inside the housing 1 and enabling the radar antenna 21 to normally transmit and receive electromagnetic waves through the notch 121, the reliability of the radar assembly 2 is improved.

[0044] The housing 1 also has a third housing 13. The first housing 11 and the third housing 13 are buckled together to form a second accommodating cavity, and the camera 3 is installed in the second accommodating cavity. By isolating the radar component 2 and the camera 3 in the two accommodating cavities of the housing 1, the electromagnetic waves reflected by the radar component 2 are prevented from causing electromagnetic interference to the electronic components of the camera 3, and the working signal emitted by the camera 3 is also prevented from having an adverse effect on the radar component 2, thereby enhancing the operational reliability of the detection device.

[0045] Figure 3 The first shell 11 and the second shell 12 provided by the utility model are shown in a schematic diagram of an exploded view in one direction. Figure 3As shown, the housing 1 further comprises a back plate 14, which is fixedly connected to the first housing 11, and the back plate 14 is fixedly connected to the output end of the motion driving mechanism 4. The back plate 14 is provided on the back of the first housing 11 to support the first housing 11, thereby increasing the structural strength of the housing 1 and realizing a reliable connection between the housing 1 and the motion driving mechanism 4. The back plate 14 is made of metal material, thereby supporting the first housing 11 and strengthening the structural strength of the housing 1 by relying on the high yield strength of the metal material itself.

[0046] In the prior art, monitoring devices are often installed outdoors, and the outdoor environment is often complex and changeable due to rain, snow, sandstorms and other weather conditions. Rain and snow are corrosive due to environmental pollution and will corrode the radar antenna. Sand and dust will gradually wear out the radar antenna. Rain, snow and sandstorms will affect the radar antenna's transmission and reception of electromagnetic waves. The radar antenna is placed in the first accommodating cavity, and a gap is opened for the radar antenna 21 to transmit and receive electromagnetic waves. Rain or sand will still enter the shell 1 through the gap between the radar antenna 21 and the shell 1, thereby causing problems such as short circuit or wind and sand wear on the radar component 2.

[0047] In order to solve the above technical problems, Figure 4 FIG. 1 shows an exploded schematic diagram of the first housing 11 and the second housing 12 provided by the present invention in another direction. Figure 4 Combination Figure 3 As shown, the radar assembly 2 also includes a wave-transmitting plate 22, which is located in the first accommodating cavity and attached to the first shell 11. The wave-transmitting plate 22 seals and covers the gap 121. The material used to make the wave-transmitting plate 22 can be any material as long as it does not affect the normal reception of electromagnetic waves by the radar antenna 21, and is preferably polymethacrylimide foam plastic (PMI material for short). By sealing and covering the wave-transmitting plate 22 on the gap 121, rain or dust is prevented from entering the shell 1 through the gap between the radar antenna 21 and the shell 1, thereby causing problems such as short circuit or wind and sand wear on the radar assembly 2.

[0048] Figure 5 The exploded schematic diagram of the camera 3 provided by the utility model is shown as follows: Figure 5 Combination Figure 3 to Figure 4 As shown, the camera 3 has a lens 31. In order to improve the image clarity of the camera 3, the first housing 11 and the second housing 12 both have a through hole 122 for the lens 31 to pass through to the outside of the housing 1. By extending the lens 31 to the outside of the housing 1, the lens 31 can directly face the object to be monitored, thereby improving the clarity of the image of the camera 3.

[0049] The camera 3 has a charge-coupled device 32 (CCD for short), wherein the CCD 32 has a large number of electronic components and is easily damaged by short circuit. In order to prevent rain or dust from entering the interior of the housing 1 through the gap between the lens 31 and the first housing 11 and the second housing 12 and causing the CCD 32 to short circuit, a second sealing strip 102 is provided between the outer wall of the lens 31 and the inner wall of the through hole 122.

[0050] Furthermore, rain or dust may still enter the housing 1 from other gaps of the housing 1, thereby damaging the CCD 32. Figure 5 As shown, the camera 3 further has a fourth housing 33, which wraps the CCD 32 from the outside, the lens 31 has a mounting end and is fixedly connected to the fourth housing 33, and a third sealing strip 103 is provided between the mounting end of the lens 31 and the fourth housing 33. By completely sealing the CCD 32 inside the fourth housing 33, the camera 3 is individually sealed, thereby further improving the operating reliability of the camera 3.

[0051] Figure 6 The exploded schematic diagram of the motion driving mechanism 4 provided by the utility model is shown as follows: Figure 6 As shown, the motion drive mechanism 4 has a first drive member 41, a second drive member 42 and a fixed platform 43. The first drive member 41 is fixed at the location of the monitoring system. The output end of the first drive member 41 is connected to the second drive member 42 and is used to drive the second drive member 42 to rotate around the first axis. The output end of the second drive member 42 is connected to the fixed platform 43 and is used to drive the fixed platform 43 to swing around the second axis. The fixed platform 43 is fixedly connected to the housing 1. The first axis and the second axis are perpendicular. By setting the motion drive mechanism 4, the monitoring range of the radar assembly 2 and the camera 3 is expanded, and the overall volume of the monitoring device is reduced.

[0052] For example, the first driving member 41 can be a first motor, the output shaft of the first motor is fixedly connected to the second driving member 42, wherein the axis of the output shaft of the first motor coincides with the first axis. The second driving member 42 can also be a second motor, the output shaft of the second motor is fixedly connected to the fixed platform 43, wherein the axis of the output shaft of the second motor coincides with the second axis. Of course, in other embodiments, the second driving member 42 can also be an integrated mechanism of a motor and a transmission mechanism, as long as the second driving member 42 can drive the fixed platform 43 to rotate around the second axis, and there is no limitation here.

[0053] Figure 7 The figure shows an exploded schematic diagram of the receiving component 5 provided by the utility model. Figure 8 The electrical schematic diagram of the monitoring device provided by the utility model is shown as follows: Figure 8 Combination Figure 7 As shown, the monitoring device also includes a receiving component 5 for receiving communication information sent by the radar component 2 and the camera 3. The receiving component 5 has a communication element 51, and the radar component 2 and the camera 3 are respectively connected to the communication element 51 through an aviation plug, and the communication element 51 is remotely connected to the host computer, so that geological disaster rescue personnel can remotely learn the working conditions of the radar component 2 and the camera 3.

[0054] Continue as Figure 8 Combination Figure 7 As shown, since the communication element 51 needs to be remotely connected with the host computer, it must use a large number of electronic components, which are still easily damaged by short circuits. In order to prevent rain or dust from entering the inside of the housing 1 through other gaps in the housing 1 and causing damage to the communication element 51, the receiving component 5 also has a fifth housing 52, and the fifth housing 52 has an upper housing 521 and a lower housing 522. The upper housing 521 and the lower housing 522 seal the communication element 51 inside the fifth housing 52 through the fourth sealing strip 104.

[0055] As an instrument, the monitoring device is bound to be damaged due to various unexpected situations, and maintenance personnel are bound to perform regular maintenance on the monitoring device in order to facilitate maintenance personnel to obtain the location information of the monitoring device in a timely manner. Figure 8 Combination Figure 7 As shown, the receiving component 5 also has a positioning module 53, which is installed inside the fifth shell 52. The positioning module 53 is preferably a global navigation satellite system (GNSS for short). The maintenance personnel only need to obtain the location information of the monitoring device through the positioning module.

[0056] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
