when the electric automobile is charged, when a user needs to know the state of the electric automobile, a command for switching the television from the normal mode to the electric automobile monitoring mode is sent to the central control module through the user terminal control module.
And after receiving the switching instruction, the central control module switches the television from the television program playing interface to the electric automobile monitoring operation interface through the signal switching module.
Then, the user can send an electric vehicle state information query instruction (such as a query instruction for detecting the charging state) to the electric vehicle monitoring module through the user electric vehicle control module. After receiving the query instruction, the electric vehicle monitoring module firstly detects whether the connection between the electric vehicle and the television is suggested; if yes, the inquiry command is modulated into a certain frequency signal through a second modulation and demodulation module, and the frequency signal is sent to the control electric automobile end through a power line.
At the electric automobile end, the first modulation and demodulation module demodulates the visit instruction signal, and the visit instruction signal is sent to the micro-processing system for decoding processing, and the system is electronically controlled. The electronic control system executes the corresponding query instruction and returns the corresponding result to the micro-processing system. And the microprocessor system sends the reported result to the TV set. And at the television end, demodulating and decoding the results reported by the electric automobile through the second modulation and demodulation module and the electric automobile monitoring module in sequence, and displaying the results on a display screen of the television.
Since the display control device of the present invention sends the control command to the electric vehicle, the method for controlling the electric vehicle to perform the corresponding operation is similar to the above-mentioned inquiry method, and is not illustrated here.
In summary, the electric vehicle remote control system, the electric vehicle state reporting and control query method provided by the invention can perform charging, security state query and related control on the electric vehicle in real time through the display control device; and the electric vehicle can report the charging state, the security state and the like of the electric vehicle to the display control equipment at any time, so that the intelligent home control in the real sense is realized. Meanwhile, in a remote control system for charging the electric vehicle, the electric vehicle and the display control equipment are controlled through a power line, so that wiring and construction cost are reduced, and the remote control system is suitable for popularization and use.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
