Background
The power system of the movable equipment in the water area such as ships comprises an outboard motor or an inboard motor (also called a horizontal motor).

When the power system is an internal ship, the GPS module can be installed in an internal mode or an external mode.

However, too long an antenna signal transmission line may cause excessive attenuation of an electrical signal transmitted from the antenna, so that the GPS signal processing unit cannot acquire the electrical signal, and of course, a thicker antenna signal transmission line may be used to solve the problem of signal attenuation, which may cause an exponential increase in antenna cost.

The present utility model provides a signal processing assembly 100, as shown in fig. 1 and 2, fig. 1 is a schematic structural diagram of an embodiment of a water area movable device of the present utility model; fig. 2 is a schematic diagram of an embodiment of the antenna module and the built-in control circuit. The signal processing assembly 100 can be externally arranged on the movable body 21 of the movable water equipment 20, in this embodiment, the movable water equipment 20 is a ship, and in other embodiments, the movable water equipment 20 may be other equipment, which is not described in detail herein.
The signal processing assembly 100 includes an antenna signal processing circuit 110, a digital signal processing circuit 120.
The antenna signal processing circuit 110 is connected to an antenna 200 externally provided on the movable body 21. The antenna 200 is used for receiving electromagnetic waves in space and converting the electromagnetic waves into analog signals. The antenna signal processing circuit 110 is a processing circuit for converting an analog signal into a first digital signal.
In the present utility model, the antenna signal processing circuit 110 and the antenna are both disposed outside the movable body 21 of the movable apparatus 20 in the water, and the antenna 200 and the antenna signal processing circuit 110 can be connected by only a short antenna signal transmission line 210, thereby effectively reducing the cost of the antenna module.
The digital signal processing circuit 120 is a processing circuit for converting a first digital signal into a second digital signal, and in this embodiment, the digital signal processing circuit 120 is a micro-control processing circuit. It should be noted that the antenna signal processing circuit 110 only converts the transmission type of the analog signal, and it does not affect the information carried in the analog signal. Similarly, the digital signal processing circuit 120 converts the first digital signal into a second digital signal of another transmission type, so as to ensure that the signal can be transmitted for a long distance without great attenuation and without affecting the information carried in the analog signal.
Specifically, the digital signal processing circuit 120 is connected to the antenna signal processing circuit 110 through the first transmission line 130 to receive the first digital signal transmitted from the antenna signal processing circuit 110 and generate a second digital signal based on the first digital signal, and the digital signal processing circuit 120 transmits the second digital signal to the built-in control circuit 400 of the water area mobile device 20 through the second transmission line 140, wherein the communication distance of the second transmission line 140 is greater than the communication distance of the first transmission line 130.
The first transmission line 130 is a dedicated line for transmitting a first digital signal, and the first digital signal is transmitted through the first transmission line 130 without being attenuated by a distance. The second transmission line is a dedicated line for transmitting the second digital signal, and the second digital signal is not attenuated by the distance when transmitted to the built-in control circuit 400 of the water area mobile device 20 through the second transmission line 140. The analog signals are sequentially converted into the first digital signals and the second digital signals in the above manner, and after the analog signals are sequentially transmitted through the first transmission line 130 and the second transmission line 140, the signals output by the antenna module 10 can be effectively ensured to be transmitted from the outside of the movable body 21 of the movable water area equipment 20 to the built-in control circuit of the movable water area equipment 20 through long distance without attenuation, and further the stability of signal transmission is ensured.
Unlike the prior art, the embodiment of the present utility model has the signal processing component 100 and the antenna 200 arranged on the movable body 21, so that the transmission distance between the antenna 200 and the antenna signal processing circuit 110 is effectively shortened, and the length of the antenna signal transmission line 210 is effectively shortened. Further, the antenna signal processing circuit 110 converts the analog signal into a first digital signal and transmits the first digital signal to the digital signal processing circuit 120, and the digital signal processing circuit 120 converts the first digital signal into a second digital signal and transmits the second digital signal to the internal control circuit 400. Meanwhile, the digital signal processing circuit 120 and the antenna signal processing circuit 110 are independently arranged, so that when a private protocol for communication is added in the product development process, the digital signal processing circuit 120 can be conveniently subjected to corresponding complementary development.
Optionally, in the present utility model, the analog signal includes at least one of a positioning signal and a mobile communication signal. That is, the analog signal may include only the positioning signal; or, the analog signal includes only the mobile communication signal; or, the analog signal includes both a positioning signal and a mobile communication signal. In this embodiment, the analog signal includes a positioning signal. In other words, the antenna 200 receives a positioning signal in space and converts the positioning signal into an analog signal. Further, the antenna signal processing circuit 110 converts the analog signal into a first digital signal, so that the first digital signal is transmitted to the digital signal processing circuit 120 through the first transmission line 130 without attenuation, so that the digital signal processing circuit 120 converts the first digital signal into a second digital signal, and is transmitted to the built-in control circuit 400 through the second transmission line 140 for a long distance without attenuation. In this way, the built-in control circuit 400 can receive the second digital signal without attenuation, so as to completely acquire the positioning signal contained in the second digital information.
The positioning signals may be GPS signals, GNSS signals, beidou signals, etc. signals containing positioning information. The mobile communication signal may be a mobile communication signal such as 4G, 5G, etc., and the water area mobile device 20 may transmit power information, position information, etc. to the cloud end through mobile communication.
Optionally, the first transmission line 130 includes a serial communication line. The serial communication path includes any one of a universal asynchronous receiver Transmitter (Universal Asynchronous Receiver/Transmitter, UART), a serial peripheral interface (Serial Peripheral Interface, SPI), and an integrated circuit bus (Inter-Integrated Circuit, IIC). In this embodiment, the serial communication line is a universal asynchronous receiver transmitter. The first transmission line 130 may be used for short-range signal transmission, and meets the communication requirement between the antenna signal processing circuit 110 and the digital signal processing circuit 120.
Optionally, the second transmission line 140 comprises a differential communication line, wherein the differential communication line comprises a controller area network (Controller Area Network, CAN) or RS-485. In this embodiment, the differential communication line is a controller area network, and the digital signal processing circuit 120 converts the first digital signal into the second digital signal, and after being connected to the internal control circuit 400 through the controller area network, the second digital signal is transmitted to the internal control circuit 400 without attenuation. The second transmission line 140 can be used for long distance signal transmission, and even if the mobile device 20 is relatively large in water area, such as a large ship, the second transmission line 140 can still meet the long distance communication requirement between the digital signal processing circuit 120 and the built-in control circuit 400.
The present utility model provides an antenna module 10, as shown in fig. 1 to 3, and fig. 3 is a schematic structural diagram of an embodiment of a housing assembly of the present utility model. The antenna module 10 includes an antenna 200, a signal processing assembly 100 and a housing assembly 300 according to any of the above embodiments.
The antenna 200 and the signal processing assembly 100 are both externally arranged on the movable body 21 of the water area movable device 20, and the antenna 200 and the signal processing assembly 100 are both disposed in the housing assembly 300, so as to ensure that the antenna 200 and the signal processing assembly 100 are not damaged by environmental factors. Specifically, the housing assembly 300 is formed with a receiving space 3212 and an installation space that are independent of each other, the antenna and signal processing assembly 100 is disposed in the receiving space 3212, an installation portion 3211 is disposed in the installation space, and the installation portion 3211 is used for installing the antenna module 10 on the movable body 21. The accommodating space and the mounting space are mutually independent, so that on one hand, the damage to the antenna 200 and the signal processing assembly 100 in the accommodating space during mounting can be avoided, on the other hand, the sealing performance of the accommodating space can be improved, and dust or water outside the danger is prevented from entering the accommodating space, so that the working performance of the antenna 200 and the signal processing assembly 100 is influenced.
Alternatively, as shown in fig. 3, wherein the housing assembly 300 includes: an upper case 310 and a lower case 320.
The receiving space 3212 and the installation space are formed in the lower case 320, and the upper case 310 is detachably coupled to the lower case 320. The upper housing 310 and the lower housing 320 are provided in a detachable connection for facilitating the subsequent installation.
The mounting portion 3211 includes mounting holes, and when the upper case 310 is connected to the lower case 320, the projection of the upper case 310 on the lower case 320 covers the mounting holes, in other words, when the upper case 310 is connected to the lower case 320, the mounting holes are not exposed to the exterior of the case assembly 300, thereby improving the aesthetic appearance of the antenna module 10.
Optionally, the antenna module 10 further includes a connector (not shown) that sequentially penetrates the mounting hole and the movable body 21 to fix the lower housing 320 to the movable body 21. In this embodiment, the connecting member is a self-tapping screw. During installation, a user takes down the upper housing 310 from the upper housing 310, passes the self-tapping screw through the installation hole of the lower housing 320 and fixes the self-tapping screw after tapping the threaded hole on the movable body 21, in this way, no need to drill holes on the movable body 21 in advance, the installation is more convenient, and the threaded hole after the self-tapping screw is self-tapped into the movable body 21 is completely covered by the housing assembly 300, thereby ensuring the aesthetic degree of the movable body 21.
Optionally, the lower housing 320 includes a main body 321 and a cover 322, the accommodating space 3212 is formed in the main body 321, the accommodating space 3212 includes an open end and a closed end, the closed end is closer to the upper housing 310 than the open end, and when the cover 322 is connected to the main body 321, the cover 322 covers the open end to seal the antenna and the signal processing assembly 100 in the accommodating space 3212. Compared with the accommodating space with both ends being open ends, the accommodating space with one closed end and the other open end is beneficial to improving the sealing performance of the accommodating space. In addition, the design that the closed end is closer to the upper housing 310 than the open end can better prevent water droplets accumulated at the top from flowing into the accommodation space. A sealing element may be further disposed between the cover portion 322 and the main body portion 321 to further seal the accommodating space, so as to more effectively prevent liquid such as water mist and water drops from penetrating into the accommodating space 3212, which causes damage to the antenna and the signal processing assembly 100.
Optionally, the antenna module 10 further includes a communication cable, where the communication cable is a cable of the second transmission line 140, and one end of the communication cable is connected to the digital signal processing circuit 120, and the other end of the communication cable can be connected to the built-in control circuit 400, where the communication cable is used for transmitting the second digital signal.
The present utility model provides a propulsion system 40, as shown in fig. 1 and 2, where the propulsion system 40 includes the antenna module 10 and the propulsion device 30 according to any of the embodiments described above.
The propulsion device 30 is provided on the movable body 21. The antenna module 10 is disposed at the highest position of the movable body 21 so as to receive electromagnetic wave signals in the space. The propulsion device 30 includes a built-in control circuit 400 and a power component 31, the built-in control circuit 400 is electrically connected with the power component 31, and the antenna module 10 transmits the second digital signal to the built-in control circuit 400 through a communication cable (the second transmission line 140) in a long distance and without attenuation. After receiving the second digital signal through the communication cable, the built-in control circuit 400 controls the power assembly 31 to operate based on the second digital signal, so as to control the water area movable equipment 20 to navigate. By the above manner, the antenna module 10 can be allowed to be arranged at any position on the movable body 21 which is convenient to install and does not affect the receiving or transmitting of electromagnetic wave signals in space, and the second digital signals cannot be attenuated, so that the position relation between the antenna module 10 and the built-in control circuit 400 is not considered when the movable body 21 is designed in an appearance structure, the propulsion system 40 can be used for movable equipment 20 in water areas with various sizes, and the scene adaptability of the propulsion system 40 is improved.
Wherein the power assembly 31 comprises a propeller type propeller. In other embodiments, the power assembly 31 may be any currently available propulsion power source, and will not be described in detail herein.
The present utility model provides a water mobile device 20 as shown in figure 1. The water movable apparatus 20 includes the propulsion system 40 and the movable body 21. The antenna module 10 is externally disposed on the movable body 21, and specifically, the above description is referred to, and the details are not repeated here.
In summary, the present utility model is different from the prior art in that the signal processing module 100 has a digital signal processing circuit 120, wherein the digital signal processing circuit 120 and the antenna signal processing circuit 110 are externally arranged on the movable body 21 of the movable apparatus 20, and the digital signal processing circuit 120 can convert the first digital signal sent by the antenna signal processing circuit 110 into the second digital signal, and then transmit the second digital signal to the built-in control circuit 400 through the second transmission line 140. Since the second transmission line 140 is suitable for long-distance communication, when the antenna module 10 is external, the length of the second transmission line 140 between the external portion and the internal control circuit 400 is not limited by signal attenuation factors, so that the antenna module 10 of the present utility model is suitable for the mobile device 20 in a water area with a smaller size and the mobile device 20 in a water area with a larger size, the length of the second transmission line 140 between the digital signal processing circuit 120 and the internal control circuit 400 can be made into an installation length meeting the design requirement of the mobile device 20 in a water area according to requirements, and the antenna signal transmission line 210 of the antenna module 10 can be made short, so that the cost of the antenna module 10 is minimum. For the mobile device 20 in a larger water area, the manner of using the longer second transmission line 140 is more advantageous in terms of cost than the manner of using the longer antenna signal transmission line 210, so that the problem of attenuation of the analog signal caused by the overlong antenna signal transmission line 210 is solved by using the second transmission line 140 to transmit the signal, the design cost is optimized, and the antenna module 10 in the external installation manner meets the requirement of generalization.
Further, in the present utility model, the digital signal processing circuit 120 is added, the digital signal processing circuit 120 can convert the first digital signal sent by the antenna signal processing circuit 110 into the second digital signal, and then transmit the second digital signal to the built-in control circuit 400, and when a proprietary protocol of a communication mode corresponding to the second transmission line 140 is added in the product development process, the corresponding complementary development of the digital signal processing circuit 120 can be conveniently performed.
Furthermore, the conventional external antenna is usually mounted by a paste type, and the connection between the antenna module 10 and the movable body 21 can be more stable by locking the connector. In addition, the mounting hole of the present utility model may be completely covered and hidden by the upper housing 310, and such a hidden opening may facilitate the installation of the antenna module 10 on the one hand, and enhance the appearance of the antenna module 10 on the other hand. In addition, the connecting piece of the utility model uses self-tapping screws, and the self-tapping screws can directly open holes on the movable body 21 after penetrating through the mounting holes of the lower shell 320, so that compared with the mode of positioning the open holes on the movable body 21 and then opening the holes, the mounting mode of the scheme of the utility model is more convenient.
