The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The inventors have appreciated that a general purpose RTK (Real-time kinematic) receiver device comprises a multi-layer structure, the assembly structure being relatively large. For example, as can be seen in fig. 1, an RTK receiver device 100 includes: upper cover 110, original antenna 120, bracket 130, original main board 140, battery 150, and lower case 160.
The original antenna 120 includes: passive board, printed circuit board, radio frequency circuit. The passive board and the radio frequency circuit are respectively arranged on the front side and the back side of the printed circuit board.
The general composition of the original motherboard 140: the System comprises a GNSS (Global Navigation Satellite System) module, a CPU (central processing unit), a wifi & bt (Blue-tooth) function, a 4G function module, an inertial Navigation element, power management, a radio station, a printed circuit board and the like. All the functional modules are arranged on the front and the back of the printed circuit board.
The bracket 130 is a metal plate, and a mounting hole for fixing the antenna is reserved on the metal plate. As will be seen below, the bracket 130 may also be designed with mounting holes for fixing the original main board 140.
The bracket 130 is located between the original antenna 120 and the original motherboard 140, and the original antenna 120 and the original motherboard 140 are connected together through the bracket by the rf connector. The support has two functions: 1) the digital signal and the radio frequency signal are shielded and isolated, after the assembly is finished, the bracket and the lower shell form a shielding cavity, and the main board and the battery are packaged in the shielding cavity to prevent electromagnetic leakage and interference lines; 2) the antenna is fixed.
The battery 150 is mounted at the bottom of the lower case 160 and connected to the original main board 140 through a connector for supplying power to various components on the original main board 140.
Although the RTK receiver device 100 described above has various required functional components, it has disadvantages, which are embodied in: 1) the material is many, and equipment failure rate is high. The antenna, the bracket and the main board are all independent components, and each independent component is provided with a set of process flow, such as plate making, patch mounting, transportation, assembly and the like. The method has the advantages of more materials, more process flows and high equipment failure rate; 2) the weight of the equipment is large, the RTK receiver equipment is handheld equipment, and users use the equipment by lifting in hands to operate, so that the difficulty of using the equipment by related users is high; 3) the number of parts is large, and the assembly complexity is high.
Based on the above studies, the inventors have appreciated that reducing the weight of the apparatus is a trend. The inventor of the application learns from some existing equipment researches that the weight of an RTK receiver device can be reduced mainly in the aspects of material types, equipment volume, materials and the like. Therefore, based on the above research, the embodiments of the present application provide a measuring device, which can reduce the material requirement of the device, and the volume and weight of the material. The measuring device provided by the present application is described below by some embodiments.
As shown in fig. 2 to 5, an embodiment of the present application provides a measurement apparatus 200, where the measurement apparatus 200 includes: printed circuit board 210, antenna 250, motherboard 240.

The main board 240 is disposed on the second surface of the printed circuit board 210.
In the measuring device 200 provided in the embodiment of the present application, since the printed circuit board 210, the antenna 250 and the main board 240 are assembled into one component, the number of components in the measuring device 200 can be reduced, the assembly difficulty of the measuring device 200 can also be reduced, and the size of the measuring device 200 can also be reduced.
To meet the functional requirements of the measurement device 200, an intelligent module 243 may be included on the motherboard 240.
Alternatively, the intelligent module 243 may be fabricated on the motherboard 240 in a high-integration embedded manner. The power consumption required to implement the functions on the intelligent module 243 can be reduced by using a highly integrated embedding approach.

In the above-mentioned measuring device 200, by installing the antenna 250 and the motherboard 240 on the printed circuit board 210, not only the material requirement of the measuring device 200 can be reduced, but also the size requirement of the measuring device 200 is relatively smaller, which is more convenient for the relevant surveying personnel to carry the measuring device 200 to perform surveying and mapping or measuring work.
In order to reduce the mutual interference between the components on the printed circuit board 210, a shielding cover may be further added to separate the components, so as to reduce the interference between the components.
Illustratively, the measurement device 200 further comprises: a first shield can.
The first shield cover is disposed on the second side of the printed circuit board 210, and the rf circuit 252 is disposed within the first shield cover.
Considering that the rf circuit 252 is easily interfered by the digital components on the motherboard 240, in order to improve the working effect of the rf circuit 252, the rf circuit 252 is covered by the first shielding case, so that the rf circuit 252 is protected from being interfered by the digital components on the motherboard 240, and the working efficiency of the antenna 250 is improved. Further, isolation without a support can also be achieved, and isolation of the antenna 250 from the motherboard 240 can also be achieved.
Optionally, the measurement apparatus 200 may further include: a second shield can.
The second shielding cover is disposed on the second side of the printed circuit board 210, and the main board 240 is disposed in the second shielding cover.
Depending on different requirements, the printed circuit board 210 of the measuring device 200 may also be provided with more shielding cases, for example, one shielding case is provided for each functional area on the printed circuit board 210.
By covering the motherboard 240 on the second side of the printed circuit board 210, the interference of the components in the motherboard 240 to the antenna 250 can be reduced, and the motherboard 240 can also be protected, so that the interference of other components on the printed circuit board 210 to the motherboard 240 can be reduced.
Optionally, a shielding layer 270 is disposed between the first side of the printed circuit board 210 and the second side of the printed circuit board 210.
The shielding layer 270 may form shielding isolation between the passive board 251 of the antenna 250 and the main board 240, and improve mutual independence between the passive board 251 of the antenna 250 and the main board 240.
Illustratively, the shielding layer 270 includes: an inner shield and an edge shield.
The inner shield is disposed between the first side of the printed circuit board 210 and the second side of the printed circuit board 210; the edge shield is wrapped around the edge of the printed circuit board 210 and is in communication with the inner shield.
For example, the inner shield and the edge shield may be electrically connected.
For example, the inner shield part and the edge shield part of the shield layer 270 may be integrally formed; or the inner shielding part may be manufactured first, and then the edge of the printed circuit board 210 is sealed to form the edge shielding part.
Through the double shielding of the inner shielding part and the edge shielding part, physical isolation can be better formed between the passive board 251 of the antenna 250 and the main board 240, and the respective working sensitivities of the passive board 251 and the main board 240 of the antenna 250 are improved.
Alternatively, the shielding layer 270 may be a copper layer.
It is contemplated that copper may also be used on the original printed circuit board 210, and the copper layer of the present embodiment is no longer used as copper in the conventional printed circuit board 210, but is used to form the shielding layer 270.
To facilitate portability of the measurement device 200, and to secure the internal components of the measurement device 200. The measurement apparatus 200 in this embodiment may further include: a first housing 220 and a second housing 230.
