Problems solved by technology
However, the inventors of the present invention have found that the existing remote controllers for electric vehicles are mainly divided into two types. One is the common OOK / ASK (on-off keying / amplitude shift keying) modulation remote controller. The user needs to manually click the button, and when it is used as an induction remote control, it is necessary to keep the OOK / ASK modulation circuit in the working state all the time, and the power consumption is too high
The other is the 2.4G induction remote control. Since the 2.4GHz frequency band is greatly affected by the external environment, the signal attenuation is large when the remote control is blocked. Therefore, this type of remote control cannot accurately control the sensing distance to a specific value. nearby

The embodiment of the invention relates to the field of electric vehicles, and discloses a remote control transmitting circuit and a receiving circuit. The remote control transmission circuit includes: a first wireless communication circuit and a radio frequency transmission circuit; when the first wireless communication circuit receives preset information from the electric vehicle, it establishes a connection with the electric vehicle, and sends a wake-up signal to the radio frequency transmission circuit to wake up the radio frequency transmission circuit ; After the radio frequency transmitting circuit is awakened, it periodically transmits a disarm command to the electric vehicle at a preset frequency and the first preset power; the preset frequency is between 150MHz and 500MHz; the first wireless communication circuit is disconnected from the electric vehicle , control the radio frequency transmitting circuit to sleep. The embodiment of the present invention is beneficial to reduce the power consumption of the remote controller and prolong the standby time of the remote controller. And the signal between 150MHz and 500MHz has strong penetration ability, less attenuation in the transmission process, and the power and distance are precisely adjustable, so the sensing distance of the remote control can be controlled more precisely.
Description
technical field [0001] Embodiments of the present invention relate to the field of electric vehicles, in particular to a remote control transmitting circuit and a receiving circuit. Background technique [0002] Electric vehicles (comprising electric bicycles, electric motorcycles, etc.) are favored by the majority of users for their advantages of lightness, flexibility, high speed, energy saving and environmental protection. However, the inventors of the present invention have found that the existing remote controllers for electric vehicles are mainly divided into two types. One is the common OOK / ASK (on-off keying / amplitude shift keying) modulation remote controller. The user needs to manually click the button, and when it is used as an inductive remote control, the OOK / ASK modulation circuit needs to be kept in the working state, and the power consumption is too high. The other is the 2.4G induction remote control. Since the 2.4GHz frequency band is greatly affected by t...
