Description

Interactive radar

Technical Field

The utility model belongs to the technical field of radars, and particularly relates to an interactive radar.

Background

Currently, two interfaces and two wires are used for a common laser radar connection, one is used for providing power, and the other is used for transmitting data. The current radar working power supply is generally 12-5V, and through long-distance wiring, for example, 100 meters, loss caused by the resistance of a cable often occurs that the voltage is greatly reduced so as to not reach the minimum required voltage for working, for example, the voltage is reduced to below 10V, and the voltage is reduced to below 4V, so that the equipment cannot be started. The existing data lines are divided into a serial interface mode and a network line, but the supported data transmission distance is not far, the serial interface mode is generally unstable when exceeding 5 meters, and the network line is generally unstable when exceeding 30 meters. In the interactive field, often the host is far away, for example over 50 meters, and it is not necessarily convenient to arrange 220V power lines on site. There is a need for wiring schemes that simultaneously ensure reliable long-range power and data transmission.

Many lidars are self-tapping, typically by mounting an external structure on the radar, such as an iron plate, and then mounting the radar in a location where work is actually required. The user needs to additionally process and design the installation fittings like iron plates, and the installation fittings are troublesome and cannot be installed when the items are tension. It is therefore preferable that the interactive radar itself has a suitable structure for installation.

Finally, the interactive radar is used as a physical device, the smaller the interactive radar is, the better the interactive radar is, and the attractive effect is achieved, because the volume of the interactive radar is required to be reduced as much as possible.

Therefore, how to make the volume of the interactive radar as small as possible and easy to install, and the interactive radar can still work stably under the working condition of long-distance wiring is a problem to be solved.

Detailed Description

One of the cores of the utility model is to provide an interactive radar which is easy to install while the volume of the interactive radar is as small as possible, and can still work stably under the working condition of long-distance wiring.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring first to fig. 1, the interactive radar disclosed in the present embodiment is applicable to the field of interactive radars, and those skilled in the art can understand that the interactive radars are applied to the field of interactive arts but the laser radar ranging principle is adopted to obtain the contact position of an object or a human body. In the field of interactive radars, many occasions require the interactive radars to be installed in the middle of an interactive area, such as desktop interaction, some ground interaction, and the like, so that the interactive radars are required to provide 360-degree scanning ranging capability.

As shown in fig. 1, the interactive radar disclosed in this embodiment includes a housing 1, an installation hanger 2, a laser ranging core 3, a driving circuit 4, and an interface 5: the mounting hanging lugs 2 are connected with the shell 1; the laser ranging core 3 is arranged in the shell 1, the laser emission position of the laser ranging core 3 protrudes out of the shell 1, and the working angle of the laser ranging core 3 is a full angle; the driving circuit 4 is electrically connected with the interface 5, and the driving circuit is adjacently arranged with the laser ranging core; the housing 1 is provided with only one interface 5, and the interface 5 is used for simultaneously realizing power supply and data communication. As shown in fig. 2, the housing 1 includes an upper case 1-1 and a lower case 1-2, the upper case 1-1 being provided with a card slot 6; in the drawings, the driving circuit 4 and the interface 5 are shown on the lower case 1-2 to show a specific position of the driving circuit 4 when the upper case and the lower case are combined, and in practice, the driving circuit 4 and the interface 5 are mounted on the upper case 1-1 in a limited manner by the clamping groove 6 of the upper case 1-1, as shown in fig. 3. The driving circuit 4 includes a data filtering module, a protocol conversion module, and a signal enhancing module (not shown in the figure).

In the actual use process, the interactive radar is generally installed on a wall or ground, and needs to be firmly installed for reliable use. The mounting lugs 2 of the embodiment can be integrated with the lower shell 1-2, and can also be separated, the mounting lugs 2 are protruded to form two whole sides, and through holes are formed in the lugs, so that a user can conveniently install the mounting lugs on a plane through screws.

The laser ranging core 3 adopts a laser ranging principle, can be a triangle ranging principle or a TOF (timeofflying) principle, and is characterized in that the working angle is 360 degrees, and the luminous position of the laser ranging core 3 protrudes out of the shell, so that the shell can not be shielded, and the ranging effect of 360 degrees is ensured.

In this embodiment, there is only one interface 5 to the outside, and the interface 5 supports PoE function, so the external device can realize power supply and data communication simultaneously only by using one common RJ45 network cable.

The driving circuit 4 in the present embodiment is connected to the laser ranging core 3 through a cable (not shown in the cable drawing). The driving circuit 4 supplies power to the laser ranging core 3 while processing data. Specifically, the driving circuit 4 further filters and calculates the original data provided by the laser ranging core 3, filters out invalid data, calculates the data as a correct ranging scanning result, converts the data into standard protocol data, and finally can be used for the user. Meanwhile, the POE protocol can be processed, and the external POE function is realized. In this embodiment, the distance between the driving circuit 4 and the laser ranging core 3 and the distance between the driving circuit and the network port are very small, and the driving circuit is placed in close contact with the edge of the interface 5, i.e. the outer edge of the embodiment, so that the design has the advantage of minimizing the volume of the radar. The driving circuit in this embodiment is further provided with a signal enhancement module, so that the signal transmission distance of the interactive radar is up to 100 meters.

The driving circuit 4 in the embodiment is arranged on the upper shell 1-1, the clamping groove 6 is arranged in the upper shell 1-1, the driving circuit 4 is clamped by the clamping groove 6 in a limiting mode, screwless installation is achieved, the size is further reduced, and the installation time is saved.

In other embodiments, the driving circuit may be a superposition of multiple circuits or may be a single circuit, which may be advantageous to further reduce the size of the interactive radar.
