Satnav video frequency remote-control device
Technical field
The utility model relates to the telepilot technical field, especially a kind of video frequency remote-control device that has GPS positioning function and GPRS communication function.
Background technology
At present, at present telepilot on the market is used for toy mostly, and common telepilot does not possess video capability and GPS positioning function, is applied on the equipment of remote intelligent very inconvenient.If controlled device exceeds sighting distance, the operator can't remote control; In case and the operator moves, just can't be calculated accurate distance when making a return voyage automatically by the equipment of remote control, so that can't calculate energy consumption required when making a return voyage, giving makes a return voyage automatically brings hidden danger.
The utility model content
At the deficiency of above prior remote controller, the purpose of this utility model provides a kind of novel video frequency remote-control device with GPS positioning function and GPRS communication function.
The purpose of this utility model is achieved by the following technical solution:
A kind of satnav video frequency remote-control device, it comprises:
Single-chip microcomputer, a keyboard that is connected with this single-chip microcomputer signal, a GPS sensor, a GPRS communication module, a wireless digital transport module, a video wireless transport module, a screen display module, reach the battery that all is electrically connected with single-chip microcomputer, GPS sensor, GPRS communication module, wireless digital transport module, video wireless transport module, screen display module, this screen display module is connected with this video wireless transport module signal.
With respect to prior art, advantage of the present utility model is:
When 1, using the utility model, the operator can still can carry out remote control to it by video image after the controlled device over the horizon;
If 2 controlled devices have certain independent navigation ability, then this equipment can judge that distance between itself and the operator is in order to estimate required return power, after the operator moved, equipment maked a return voyage and a little changes, and can make a return voyage this moment according to the GPS location positioning of telepilot;
3, the communication between telepilot and the controlled device can be by GPRS and wireless digital transport module dual mode, the priority of wireless digital transport module is higher, when a kind of communication apparatus loss signal, another kind of communication apparatus is started working automatically, has so significantly reduced the possibility of Communications failure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the module diagram of satnav video frequency remote-control device of the present utility model.
Embodiment
As shown in Figure 1, this satnav video frequency remote-control device comprises a single-chip microcomputer, a keyboard that is connected with this single-chip microcomputer signal, a GPS sensor, a GPRS communication module, a wireless digital transport module, a video wireless transport module, a screen display module, reach the battery that all is electrically connected with single-chip microcomputer, GPS sensor, GPRS communication module, wireless digital transport module, video wireless transport module, screen display module, this video wireless transport module is connected with the screen display module signal.
As had certain independent navigation ability by the equipment of remote control, then this equipment need judge that distance between itself and the operator is in order to estimate required return power, after hand-held this satnav video frequency remote-control device of operator moves, equipment makes a return voyage and a little changes, single-chip microcomputer in the telepilot reads the positioning signal of GPS sensor in real time and passes through GPRS communication module or wireless digital transport module and controlled device communication, the operator's that the GPS sensor is located bearing data sends to controlled device, and controlled device makes a return voyage according to the location positioning of described telepilot.
Communication between satnav video frequency remote-control device and the remotely-controlled equipment is by GPRS communication module and digital radio communication module dual mode, the priority of digital radio transport module is higher, when the digital radio transport module does not receive the signal of controlled device, the GPRS communication module is started working.
When the video wireless transmission function is opened, single-chip microcomputer is transferred to controlled device by the instruction that GPRS communication module or wireless digital transport module will carry out the video communication connection, video sending module on the controlled device is started working, and this moment, the screen wireless transport module of telepilot began to receive the vision signal of controlled device and be presented on the screen.
Single-chip microcomputer reads the signal of keyboard in real time, by GPRS communication module or wireless digital transport module instruction is transferred to controlled device again.
Single-chip microcomputer is by GPRS communication module or wireless digital transport module and controlled device communication, obtain the gps coordinate of controlled device, single-chip microcomputer utilizes the coordinate of the coordinate of controlled device and telepilot position can calculate air line distance between telepilot and the controlled device; Simultaneously telepilot sends the coordinate of self position in real time, helps controlled device to calculate whether to have the enough energy to make a return voyage smoothly.
