Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The RTK measurement apparatus 200 and system of the present invention will be described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Example one

Referring to fig. 1, 3, 7 and 9, an RTK measuring apparatus 200 according to an embodiment of the present invention may include a support rod 1, an RTK antenna device 2, a support frame 3, a suspension 4 and a wire (not shown). The RTK antenna device 2 is installed at the top end of the supporting rod 1, and the RTK antenna equipment is supported through the supporting rod 1. Alternatively, the RTK antenna apparatus 2 performs detection based on GPS (Global Positioning System) navigation to obtain coordinate information of a point to be detected. Of course, the RTK antenna apparatus 2 may also detect based on beidou or other navigation. The support frame 3 is connected with the middle part of the support rod 1. The support frame 3 of the present embodiment is used for supporting the support rod 1 so that the support rod 1 can be in a standing state. For example, when the support frame 3 is supported on the ground, the upright state of the support bar 1 means that the central axis of the support bar 1 is substantially perpendicular to the ground. The hanging member 4 is disposed at the rear end of the supporting rod 1 for hanging the battery 100 (herein, the battery 100 is a main battery), so as to prevent the battery 100 from being lost, and the battery 100 can also be used as a weight member of the supporting frame 3, so that the supporting frame 3 can be more stably supported on the ground or other supporting surfaces.

One end of the wire is electrically connected with the RTK antenna device 2, and the other end of the wire is provided with an electrical connector for electrically connecting with the battery 100, so that the battery 100 supplies power to the RTK antenna device 2. When the RTK antenna device is used, the RTK antenna device 2 can be powered through the battery 100 through the plug-in fit of the electric connecting piece and the electric mating piece on the battery 100, and the operation is convenient and fast. By providing electrical connections, replacement of the battery 100 is facilitated. Alternatively, the electrical connector may be an electrical socket or an electrical plug. When the electrical connector is an electrical socket, the electrical mating member on the battery 100 is an electrical plug for mating with a phase electrical socket. When the electrical connector is an electrical plug, the electrical mating member on the battery 100 is an electrical socket for mating with the electrical plug. In this embodiment, the wire is inserted into the support rod 1, so that the outside of the RTK measuring device 200 is not wired, and the wire is prevented from being wound, thereby prolonging the service life of the wire and improving the aesthetic property of the product.

In this embodiment, when the battery 100 is hung on the hanger 4, the electrical connector can be electrically connected to the battery 100, so that the battery 100 can be used as a weight of the support frame 3 while supplying power to the RTK antenna apparatus 2. In the embodiment of the invention, the hanging piece 4 is arranged at the tail end of the support rod 1, so that the battery 100 for supplying power to the RTK antenna device 2 can be hung on the hanging piece 4, and the battery 100 is prevented from being lost. Also, the battery 100 is hung on the hanger 4, and the weight of the battery 100 provides a weight to the support stand 3, so that the support stand 3 can be more stably supported on the ground.

The support frame 3 of this embodiment detachably connects in the middle part of bracing piece 1, makes things convenient for accomodating and transporting of RTK measuring equipment 200. Specifically, the supporting frame 3 may include a sleeve 31 and a plurality of foot rests 32 connected to outer edges of the sleeve 31. Wherein, the sleeving piece 31 is sleeved and fixed in the middle of the supporting rod 1. Further, the supporting frame 3 further includes a locking portion 33 for locking the sleeve 31 at the middle portion of the supporting rod 1 to prevent the supporting frame 3 from sliding relative to the supporting rod 1. The locking portion 33 may be a bolt or other locking structure. In addition, the number of the foot rests 32 can be determined according to the weight of the support rod 1, the weight of the RTK antenna device 2 and other factors, and preferably, the support frame 3 is a tripod 32.

Referring to fig. 2 and 4, the suspension member 4 may include a fixing base 41 and a hanging ring 42. Wherein, the fixing seat 41 is fixed on the support rod 1. The fixing part can be clamped, sleeved or fixed at the tail part of the supporting rod 1 by adopting other modes. In one embodiment, the fixing base 41 may include a sleeve portion 411 for being sleeved on the supporting rod 1. Referring to fig. 4, the covering portion 411 of the present embodiment is a through hole, and when the suspension member 4 needs to be fixed to the tail end of the supporting rod 1, the tail end of the supporting rod 1 is directly inserted into the through hole, and the covering portion 411 can be locked on the supporting rod 1 by screwing or by screws, so as to prevent the covering portion 411 from sliding relative to the supporting rod 1.

The hanging ring 42 is connected to the fixing base 41, and the hanging ring 42 of this embodiment is used for hanging the battery 100. Alternatively, the hanging ring 42 is oval, circular, or other annular configuration. Preferably, the hanging ring 42 is oval in shape, has a small volume, and improves the aesthetic appearance of the product structure.

The hanging ring 42 can be fixedly connected or movably connected with the fixed seat 41. For example, in an embodiment, the hanging ring 42 is fixedly connected to the fixing base 41, an included angle between the hanging ring 42 and the fixing base 41 is fixed, and the hanging ring 42 cannot rotate relative to the fixing base 41 to fold the hanging ring 42 and the fixing base 41, which is inconvenient to use.

In another embodiment, the hanging ring 42 is rotatably connected to the fixing base 41, and the hanging ring 42 rotates relative to the fixing base 41 to selectively be in an unfolded state or a folded state, so as to facilitate the use of the user. In this embodiment, before the battery 100 is hung by the hanging member 4, the hanging ring 42 can be rotated to the unfolded state relative to the fixing base 41. When the hanger 4 is not needed, the hanging ring 42 can be rotated to the folded state relative to the fixed seat 41, so that the hanger 4 can be conveniently stored. Specifically, when the hanging ring 42 rotates to the unfolding state relative to the fixed seat 41, the hanging ring 42 and the fixed seat 41 form a preset included angle. Alternatively, when the hanging ring 42 rotates to the unfolded state relative to the fixed base 41, the hanging ring 42 and the fixed base 41 form an angle of approximately 90 ° (unit: degree). Hang and establish ring 42 for fixing base 41 rotates to when fold condition, hang and establish ring 42 laminating on the fixed part to when suspension 4 does not use, through hanging the mode of establishing ring 42 and fixing base 41 folding, reduce the submission of suspension 4, conveniently accomodate suspension 4.

Further, referring to fig. 2 and 4, a connecting portion 44 is disposed at the bottom of the fixing seat 41, and the hanging ring 42 is rotatably connected to the connecting portion 44. In one embodiment, the hanging ring 42 is hingedly connected to the connecting portion 44. In another embodiment, referring to fig. 2 and 4, a through hole is formed in the connecting portion 44, and the hanging ring 42 is movably sleeved in the through hole, so that the hanging ring 42 can be rotatably connected with respect to the fixing base 41.

In addition, in some examples, the connecting portion 44 may be integrally formed with the fixing base 41, so as to improve the strength of the structure. In other examples, the connection portion 44 is a separate component. The connecting portion 44 may be fixed to the fixing base 41 by clipping, screwing or other methods. In this embodiment, referring to fig. 2, the fixing base 41 is provided with a mounting hole, and the connecting portion 44 penetrates through the mounting hole and is fixed in the mounting hole by a fixing member 45 (such as a bolt).

With reference to fig. 5 and 6, the hanging ring 42 may include a first ring 421 and a second ring 422. One end of the first ring member 421 is rotatably connected to one end of the second ring member 422, and the first ring member 421 rotates relative to the second ring member 422, so that the hanging ring 42 can be selectively in an open state or a closed state. Specifically, when the first ring member 421 rotates to the open state relative to the second ring member 422, the other ends of the first ring member 421 and the second ring member 422 are separated from each other, and the free end of the first ring member 421 penetrates through a part of the battery 100, so that the battery 100 is hung on the hanging ring 42. When the first ring member 421 rotates to the closed state relative to the second ring member 422, the other ends of the first ring member 421 and the second ring member 422 are locked with each other, so that the hanging ring 42 forms a sealing ring to prevent the battery 100 from falling off from the hanging ring 42.

In this embodiment, the first ring member 421 and the second ring member 422 are vertically engaged, and the first ring member 421 is located below the second ring member 422. Optionally, the first ring member 421 rotates up and down relative to the second ring member 422, so that the hanging ring 42 can be selectively in an open state or a closed state. In this embodiment, when the hanging ring 42 is in the closed state, the first ring body 421 can be rotated downward relative to the second ring body 422, so that the other ends of the first ring body 421 and the second ring body 422 are separated from each other, and at this time, the hanging ring 42 is in the open state. When the hanging ring 42 is in the open state, the first ring member 421 can be rotated upward relative to the second ring member 422, so that the other ends of the first ring member 421 and the second ring member 422 are locked. Optionally, the first ring member 421 rotates left and right relative to the second ring member 422, so that the hanging ring 42 can be selectively in an open state or a closed state. In this embodiment, with reference to fig. 5 and fig. 6, when the hanging ring 42 is in the closed state, the first ring body 421 can be rotated rightward relative to the second ring body 422, so that the other ends of the first ring body 421 and the second ring body 422 are separated from each other, and at this time, the hanging ring 42 is in the open state. When the hanging ring 42 is in the open state, the first ring member 421 can be rotated to the left relative to the second ring member 422, so that the other ends of the first ring member 421 and the second ring member 422 are locked. While in other embodiments, the first ring member 421 and the second ring member 422 are left-right mated, e.g., the first ring member 421 is positioned on the right side of the second ring member 422. The left-right matching manner of the first ring member 421 and the second ring member 422 is similar to the up-down matching manner of the first ring member 421 and the second ring member 422, and details are not repeated here.

Further, with reference to fig. 5 and 6, the hanging ring 42 may further include a locking member 423, and the other ends of the first ring member 421 and the second ring member 422 are locked to each other by the locking member 423. In one embodiment, the locking member 423 is a separate component, and one end of the locking member 423 is connected to the first ring member 421, and the other end is connected to the other end of the second ring member 422. In this embodiment, the locking member 423 is directly connected to the first ring member 421 and the second ring member 422. Optionally, the locking member 423 can be threadedly coupled to the first ring member 421, and the locking member 423 can be directly coupled to the first ring member 421 by other means (e.g., snap fit). Optionally, the locking member 423 and the second ring 422 are also threadably coupled or directly coupled by other means (e.g., snap fit).

In another embodiment, the locking member 423 is part of the mounting ring 42. Optionally, the locking member 423 includes a clamping end disposed on the first ring 421 and a clamping groove disposed at the other end of the second ring 422. When the first ring body 421 rotates to the open state relative to the second ring body 422, the engaging end and the engaging groove are separated from each other, so that the other ends of the first ring body 421 and the second ring body 422 are separated from each other. When the first ring body 421 rotates to the closed state relative to the second ring body 422, the clamping end and the clamping groove are in inserted fit, so that the other ends of the first ring body 421 and the second ring body 422 are locked with each other. Of course, the positions of the clamping ends and the clamping grooves can be interchanged. Preferably, the clamping ends comprise a plurality of clamping ends, the clamping ends are the same in size, and the clamping ends are not collinear. Correspondingly, the clamping grooves are also multiple, and the size and the position of the clamping grooves correspond to the size and the position of the clamping ends, so that the other ends of the first ring body 421 and the second ring body 422 can be locked more firmly.

In this embodiment, the hanging ring 42 may be made of metal, plastic or other materials.

Furthermore, the hanging member 4 may further include a hanging portion 43, the hanging ring 42 is hung on the battery 100 through the hanging portion 43, and the hanging portion 43 is movably hung on the hanging ring 42. In this embodiment, the hanging portion 43 is directly connected to the battery 100, and the hanging portion 43 is connected to the hanging ring 42, so that the hanging ring 42 does not need to be large in size. Preferably, the hanging portion 43 is made of a flexible material.

Referring to fig. 4, the hanging portion 43 may include a hanging strip 431 for covering a portion of the battery 100, wherein two sides of the hanging strip 431 are respectively provided with a loop 432. When the first ring body 421 rotates to the open state relative to the second ring body 422, each sleeve ring 432 is inserted into the free end of the first ring body 421, so that the sleeve ring 432 is sleeved on the hanging ring 42. Referring to fig. 8, in the embodiment, the battery 100 includes a battery box 110 and a handle 120, the handle 120 is disposed on the top of the battery box 110, a holding space 130 is formed between the handle 120 and the top of the battery box 110, one end of the strap 431 is inserted into the holding space 130, so that the strap 431 is sleeved on the handle 120, and then the sleeved rings at two ends of the strap 431 are inserted from the free end of the first ring body 421, so that each sleeved ring is sleeved on the hanging ring 42. In this embodiment, the hanging strip 431 is made of a flexible material, so that the battery 100 can be hung conveniently without scratching the battery 100.

The battery 100 suspended on the hanger 4 is used as a main battery of the RTK measuring apparatus 200. Further, with reference to fig. 10 to 21, the RTK measuring apparatus 200 may further include a backup battery 5 and a control unit 6. The backup battery 5 is connected with the support rod 1. The backup battery 5 can be electrically connected to the RTK antenna apparatus 2 to supply power to the RTK antenna apparatus 2. The control unit 6 is used for starting the backup battery 5 to supply power to the RTK antenna when the main battery is disconnected with the electric connector. Specifically, when the main battery is conductively connected to the electrical connector and supplies power to the RTK antenna device 2, the backup battery 5 stops supplying power to the RTK antenna device 2. When the electric quantity of the backup battery 5 is lower than a first preset electric quantity, the main battery charges the backup battery 5. That is, when the electric quantity of the main battery is sufficient (the electric quantity of the main battery is greater than or equal to the second preset value), the RTK antenna apparatus 2 is powered by the main battery, and meanwhile, if the electric quantity of the backup battery 5 is lower than the first preset electric quantity, the backup battery 5 is charged by the main battery. In the embodiment, the main battery and the auxiliary battery 5 are also electrically connected through a lead, and when the main battery and the electric connector are electrically connected, the main battery and the auxiliary battery 5 are electrically connected. The first preset value and the second preset value may be empirical values. Because the RTK antenna device 2 is powered through the spare battery 5 in the process that the main battery is disconnected with the electric connector, when the main battery is conducted with the electric connector again and is used for powering the RTK antenna device 2, if the spare battery 5 is not charged through the main battery, the main battery is disconnected with the electric connector next time, the electric quantity of the spare battery 5 may not be enough to support the RTK antenna device 2 to work, so the main battery is used for repeatedly charging the spare battery 5, the spare battery 5 can be repeatedly used for powering the RTK antenna device 2, uninterrupted power supply of the RTK antenna device 2 is achieved, and the operation efficiency is improved.

In the embodiment of the invention, the standby battery 5 is arranged to be matched with the main battery, when the main battery is disconnected with the RTK antenna device 2, the RTK antenna device 2 can be powered through the standby battery 5, and when the electric quantity of the standby battery 5 is lower than a first preset electric quantity, the standby battery 5 is charged through the main battery, so that the RTK antenna device 2 is ensured to be powered uninterruptedly. The standby battery 5 is used as a temporary energy supply source of the RTK antenna device 2 in the replacement process of the main battery, so that the working time of the RTK measuring equipment 200 is greatly prolonged, and the support of large-area surveying and mapping operation is realized.

Wherein, the standby battery 5 can be connected with the support rod 1 in any way. For example, in one embodiment, the backup battery 5 can be accommodated in the support rod 1, which can prevent the backup battery 5 from being lost and prevent the backup battery 5 from being corroded by moisture in the air.

In another embodiment, referring to fig. 10 and 11, the backup battery 5 is cylindrical and is fixedly connected to the support rod 1 coaxially, so that the length of the support rod 1 can be extended, and the use by a surveying and mapping staff is facilitated. The following embodiment will be further described by taking the backup battery 5 as a cylindrical shape and fixedly connected to the support rod 1 coaxially.

In this embodiment, the support bar 1 may include a first support bar 11 and a second support bar 12. One end of the standby battery 5 is connected to the first supporting rod 11, the other end of the standby battery is connected to the second supporting rod 12, and the RTK antenna device 2 is disposed on one side of the first supporting rod 11, which is far away from the standby battery 5. Alternatively, one end of the backup battery 5 is non-detachably connected to the first support rod 11, and the other end of the backup battery 5 is non-detachably connected to the second support rod 12, in such a way that the backup battery 5 cannot be replaced after the backup battery 5 is damaged, which affects the use of the RTK measuring apparatus 200. In this embodiment, one end of the backup battery 5 is detachably connected to the first support rod 11, and the other end of the backup battery 5 is detachably connected to the second support rod 12, so that the backup battery 5 can be conveniently replaced after the backup battery 5 is damaged, and the use of the RTK measuring device 200 is not affected.

The detachable connection of the first support bar 11 and the backup battery 5, and the detachable connection of the second support bar 12 and the backup battery 5 will be described below.

With reference to fig. 12, 14 to 16, a first fixing end 110 may be disposed on a side of the first support rod 11 facing the battery pack 5, and a second fixing end 120 may be disposed on a side of the second support rod 12 facing the battery pack 5. Accordingly, the backup battery 5 has a first connection terminal 51 at one end for being coupled to the first fixed terminal 110 and a second connection terminal 52 at the other end for being coupled to the second fixed terminal 120.

The first fixing end 110 is provided with a first electrical contact end 111, and a corresponding position of the first connection end 51 is provided with a first electrical interface 511 for electrically mating with the first electrical contact end 111. The second fixed end 120 is provided with a second electrical contact end 121, and a second electrical interface 521 for electrically mating with the second electrical contact end 121 is disposed at a position corresponding to the second connection end 52.
