Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a remote control transmitting circuit. The remote control transmitting circuit may be provided inside a remote controller, which may be a remote controller for controlling an electric vehicle (electric bicycle, electric motorcycle, etc.).
As shown in fig. 1, the remote control transmitting circuit includes a first wireless communication circuit 1, a radio frequency transmitting circuit 2 and a key circuit 3; the radio frequency transmitting circuit 2 is respectively connected to the first wireless communication circuit 1 and the key circuit 3, and can respectively perform communication interaction with the first wireless communication circuit 1 and the key circuit 3.
Specifically, the first wireless communication circuit 1 may establish a connection relationship with a corresponding wireless communication circuit on the electric vehicle upon receiving the preset information from the electric vehicle. In one example, the preset information may be a connection request. Specifically, the first wireless communication circuit 1 may be configured to periodically transmit a broadcast signal to the outside, and when the distance between the remote controller and the electric vehicle is shortened to a certain range (the communication range of the first wireless communication circuit) during the process that the remote controller approaches the electric vehicle, the corresponding wireless communication circuit on the electric vehicle may receive the broadcast signal, and at this time, the electric vehicle may send a connection request to the first wireless communication circuit 1 to establish a connection with the first wireless communication circuit 1. In another example, the preset information may be a broadcast signal. Specifically, the corresponding wireless communication circuit on the electric vehicle may be configured to periodically transmit the broadcast signal to the outside, and when the distance between the remote controller and the electric vehicle is shortened to a certain range (the communication range of the first wireless communication circuit), the first wireless communication circuit 1 may receive the broadcast signal from the electric vehicle, thereby establishing a connection with the electric vehicle.
When the first wireless communication circuit 1 is connected with the electric vehicle, the first wireless communication circuit 1 can send a wake-up signal to the radio frequency transmitting circuit 2 to trigger the radio frequency transmitting circuit 2 to enter a working state from a sleep state. After the radio frequency transmitting circuit 2 is awakened, a disarming instruction is periodically transmitted to the electric vehicle at a preset frequency and a first preset power, so as to trigger the electric vehicle to execute an operation corresponding to the disarming instruction. The predetermined frequency may be set between 150MHz and 500 MHz. In this embodiment, the preset frequency is preferably 433MHz or 315 MHz.
In practical application, the specific size of the first preset power can be flexibly set according to needs. In order to more accurately control the induction distance of the remote controller, the remote controller is prevented from automatically controlling the electric vehicle when the remote controller is far away from the electric vehicle, and the safety of the electric vehicle is prevented from being influenced. The first preset power can be set to be a smaller power (such as 0dB), so that the electric vehicle can successfully receive the disarming instruction when the distance between the remote controller and the electric vehicle is shortened to a smaller value, and then the disarming operation is performed.
After the electric vehicle is disarmed, the radio frequency transmitting circuit 2 continues to periodically transmit a disarmed instruction to the electric vehicle at a preset frequency and a first preset power. When the electric vehicle cannot receive a disarming instruction sent by the remote controller (for example, the remote controller moves towards a direction far away from the electric vehicle, and the distance between the remote controller and the electric vehicle exceeds the current communication range of the radio frequency transmitting circuit 2), the electric vehicle can automatically perform the arming operation. At this time, the rf transmitting circuit 2 still periodically transmits the disarming command to the electric vehicle at the predetermined frequency and the first predetermined power. When the first wireless communication circuit 1 is disconnected from the electric vehicle (the distance between the remote controller and the electric vehicle is too far and exceeds the communication range of the first wireless communication circuit 1), the first wireless communication circuit 1 sends a closing signal to the radio frequency transmitting circuit 2 to control the radio frequency transmitting circuit 2 to sleep.
As can be seen from this, in the present embodiment, after the radio frequency transmitting circuit 2 is awakened, the disarming instruction is periodically transmitted to the electric vehicle at the preset frequency and the first preset power until the first wireless communication circuit 1 is disconnected from the electric vehicle. When the electric vehicle receives the disarming instruction for the first time, the disarming operation is carried out; after the electric vehicle is disarmed, and when the disarmed instruction cannot be received, the electric vehicle can be automatically armed. In practical application, the electric vehicle can be set to automatically perform arming after disarming and when a disarming instruction is not received within a preset time, so that the accuracy of judgment is improved. The predetermined time should be greater than the period of time for which the disarming instruction is issued.
In addition, the period for transmitting the disarming instruction can also be set according to the actual situation, and the radio frequency transmitting circuit 2 can be arranged to transmit the disarming instruction according to the frequency once per second in the embodiment.
When the user manually operates the key, the key circuit 3 receives the key operation signal and sends a wake-up signal and a key operation signal to the radio frequency transmitting circuit 2. The wake-up signal may wake up the rf transmitting circuit 2, i.e. trigger the rf transmitting circuit 2 to enter a working state from a sleep state. After the radio frequency transmitting circuit 2 is awakened, a corresponding remote control instruction can be generated according to the key operation signal, and the remote control instruction is sent to the corresponding electric vehicle at a preset frequency and a second preset power so as to trigger the electric vehicle to execute the operation corresponding to the key operation signal. The second preset power is larger than the first preset power.
Considering that the distance between the remote controller and the electric vehicle is possibly far, the second preset power can be set to be larger power (the range of the second preset power can be between 5dB and 8 dB), so that a user can send a remote control instruction to the electric vehicle by using the remote controller at a far place from the electric vehicle, and the electric vehicle can be remotely controlled.
In practical application, each key signal and each preset remote control instruction can be bound and stored in a one-to-one correspondence manner. When the radio frequency transmitting circuit 2 is awakened, the corresponding remote control instruction can be searched from the prestored information according to the currently received key operation signal, and when the corresponding remote control instruction is searched, the searched remote control instruction is sent to the corresponding electric vehicle.
It should be noted that, when the electric vehicle receives the remote control command, the current operation mode is locked in the manual operation mode, and the locked state is maintained for a period of time. In this period, the induction mode of the electric vehicle temporarily fails, that is, the electric vehicle does not receive the disarming instruction transmitted by the radio frequency transmitting circuit 2 at the preset frequency and the first preset power, and also does not automatically perform disarming because the disarming instruction transmitted by the radio frequency transmitting circuit 2 at the preset frequency and the first preset power cannot be received. After the period of time, the electric vehicle can recover the induction mode, and has the opportunity to receive the disarming instruction transmitted by the radio frequency transmitting circuit 2 at the preset frequency and the first preset power again.
Compared with the prior art, the radio frequency transmitting circuit is awakened only when the first wireless communication circuit receives the broadcast signal of the electric vehicle or the key circuit receives the key operation signal, so that the power consumption of the remote controller is reduced, and the standby time of the remote controller is prolonged. Meanwhile, the signal between 150MHz and 500MHz has strong penetration capacity, less attenuation in the transmission process and accurate adjustment of power and distance, so that the sensing distance of the remote controller can be controlled more accurately. After a radio frequency transmitting circuit in the remote controller is awakened, periodically transmitting a disarming instruction at a preset frequency and a first preset power, and when the remote controller enters a transmitting range of the first preset power, receiving the disarming instruction by the electric vehicle and performing disarming operation; after the electric vehicle is disarmed, the remote controller still periodically sends the instruction of removing the troops on garrison, when the remote controller leaves the transmission scope of first default power, the electric vehicle just can not receive the instruction of removing the troops on garrison duty, and the electric vehicle will be set up the troops on garrison duty by oneself this moment, and this is favorable to promoting user's experience.
A second embodiment of the present invention relates to a remote control transmitting circuit. The second embodiment is a further improvement on the first embodiment, and the main improvement is that: in this embodiment, the first wireless communication circuit is a Bluetooth Low Energy (BLE) communication circuit.
The low-power consumption Bluetooth communication circuit has low energy consumption, is favorable for further reducing the energy consumption of the remote controller when the remote controller is used as an induction remote controller, and prolongs the standby time of the remote controller.
In addition, it is worth mentioning that, in this embodiment, when receiving the preset information from the electric vehicle, the first wireless communication circuit may first determine whether the electric vehicle is a corresponding electric vehicle according to the preset information, and when determining that the electric vehicle is a corresponding electric vehicle, establish a connection with the electric vehicle, and send the wake-up signal to the radio frequency transmitting circuit after establishing the connection.
In practical application, the preset information can carry identification information of a corresponding electric vehicle, and the first wireless communication circuit can judge whether the electric vehicle is the electric vehicle corresponding to the current remote controller through the identification information.
In addition, the radio frequency transmitting circuit in this embodiment may be an on-off keying (OOK) modulation circuit or an Amplitude Shift Keying (ASK) modulation circuit.
Compared with the first embodiment, the embodiment selects the low-power-consumption Bluetooth communication circuit as the first wireless communication circuit, thereby being beneficial to further reducing the power consumption of the remote controller. The inventor researches and discovers that the radio frequency transmitting circuit is in a dormant state when not working, the low-power-consumption Bluetooth communication circuit is selected as the first wireless communication circuit, the power consumption of the induction remote controller can be greatly reduced, and the standby of 18 months can be realized by adopting a CR2032 button cell. In addition, when receiving the preset information from the electric vehicle, firstly whether the electric vehicle is the corresponding electric vehicle or not, and when judging that the electric vehicle is the corresponding electric vehicle, sending the wake-up signal to the radio frequency transmitting circuit, on one hand, the accuracy of matching the remote controller and the electric vehicle is improved, and on the other hand, the power consumption is reduced.
A third embodiment of the present invention relates to a receiving circuit. The receiving circuit can be arranged in the electric vehicle, and the receiving circuit can be used in cooperation with the remote control transmitting circuit described in the first embodiment or the second embodiment.
As shown in fig. 2, the receiving circuit includes a second wireless communication circuit 4, a radio frequency receiving circuit 5 and a vehicle control logic circuit 6; wherein, the radio frequency receiving circuit 5 is connected with the vehicle control logic circuit 6.
Specifically, in the present embodiment, the second wireless communication circuit 4 corresponds to the first wireless communication circuit 1 described in the first embodiment or the second embodiment, and can transmit the preset information to the first wireless communication circuit 1. In one example, the preset information may be a connection request. Specifically, the first wireless communication circuit 1 may be configured to periodically transmit a broadcast signal to the outside, and when the distance between the remote controller and the electric vehicle is shortened to a certain range, the second wireless communication circuit 4 may receive the broadcast signal, and at this time, the second wireless communication circuit 4 may transmit a connection request to the first wireless communication circuit 1 to establish a connection with the first wireless communication circuit 1. In another example, the preset information may be a broadcast signal. Specifically, the second wireless communication circuit 4 may be configured to periodically transmit a broadcast signal to the outside, and when the first wireless communication circuit 1 receives the broadcast signal, the connection relationship between the two circuits may be established. In order to reduce the power consumption of the electric vehicle, the second wireless communication circuit can adopt a low-power Bluetooth communication circuit.
The rf receiving circuit 5 corresponds to the rf transmitting circuit 2 of the first or second embodiment, and also operates at a predetermined frequency, which may be set between 150MHz and 500 MHz. In this embodiment, the preset frequency is preferably 433MHz or 315 MHz. When receiving the disarming instruction sent by the radio frequency transmitting circuit 2, the radio frequency receiving circuit 5 sends a preset first control signal to the vehicle control logic circuit 6 to control the vehicle control logic circuit to perform disarming operation on the electric vehicle. After the disarming operation is performed on the electric vehicle, if the radio frequency receiving circuit 5 continuously receives a disarming instruction which is periodically sent by the radio frequency transmitting circuit 2 at a preset frequency and a first preset power, no processing is required; when the radio frequency receiving circuit 5 suddenly fails to receive the arming instruction periodically sent by the radio frequency receiving circuit 5 at the preset frequency and the first preset power at a certain moment, the arming operation of the electric vehicle is performed. That is, after the electric vehicle is disarmed, and when the radio frequency receiving circuit 5 cannot receive the disarming instruction periodically sent by the radio frequency receiving circuit 5 at the preset frequency and the first preset power, the radio frequency receiving circuit 5 sends the preset second control signal to the vehicle control logic circuit 6, so as to control the vehicle control logic circuit 5 to disarme the electric vehicle.
When receiving the remote control command sent by the radio frequency transmitting circuit 2, the radio frequency receiving circuit 5 sends a preset third control signal to the vehicle control logic circuit 6, and controls the vehicle control logic circuit 6 to execute an operation corresponding to the remote control command.
The radio frequency transmitting circuit 5 in this embodiment may be an on-off keying (OOK) modulation circuit or an Amplitude Shift Keying (ASK) modulation circuit.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
