Detailed Description
A multi-purpose remote controller:
scheme 1: 1 universal key is responsible for the electric motor car switch, drives the electric door lock moreover, and the key function is exempted from in direct use, and 3 special keys are responsible for the switching of electric motor car gear, soft or hard starting, battery voltage model respectively in addition. Because the user knows the state of the electric vehicle without mistakes in cooperation with the voice feedback.
The universal key 1 is switched back and forth by pressing the corresponding electric vehicle switch each time. The original state is switched on and then switched off; otherwise, the switch is turned on when the switch is turned off. Meanwhile, the meter or the burglar alarm plays the switch state or different prompt tones by voice. The other 3 conventional key functions are cancelled.
The special key 1 is pressed each time to switch between high, medium and low gears, and simultaneously the meter or the burglar alarm plays the gear state by voice. The original high grade is switched to the middle grade, the original middle grade is switched to the low grade, and the original low grade is switched to the high grade.
The special key 2 is switched between soft and hard starting when pressed each time, and the instrument or the burglar alarm plays soft and hard states by voice. The original soft start is pressed again to be a hard start, and the original hard start is pressed again to be a soft start to switch back and forth.
The dedicated key 3 switches between 48v and 60v battery at each press while the meter or burglar alarm plays the battery voltage in voice. The original 48v is further pressed as 60v, and the original 60v is further pressed as 48v, and switching is performed back and forth. The motor controller is customized for a universal motor controller, and the same controller can be installed on the electric vehicle with two storage batteries.
According to the scheme, under the condition that the keys of the traditional remote controller are not changed, 6 wires of the motor controller 3 are reduced. The traditional scheme is that two lines for gear shifting are connected to a motor controller from an electric vehicle instrument through long large lines, and 1 switch and a related plug wire head are arranged on a handlebar. The saving effect of the invention is very obvious.
Scheme 2: 3 general keys are responsible for traditional function, and 1 special key is responsible for the switching of electric motor car gear respectively in addition. The original function of the 'ring' key is cancelled and the key is rearranged into a special key. The principle of voice playing is the same as above.
Scheme 3: 1 universal key is responsible for the switch of the electric vehicle, and drives the electric door lock, and directly uses the function of exempting from the key, and the other 3 special keys are responsible for the gear of the electric vehicle-high grade, middle grade, low grade respectively. The principle of voice playing is the same as above.
Scheme 4: the functions of original traditional 4 keys are kept, and in addition, 6 special keys are additionally arranged and are respectively responsible for electric vehicle gear, soft and hard starting, storage battery voltage model, motor phase learning, speed limiting and switching of dry electricity and water of a charger. The principle of voice playing is the same as above.
By analogy, more remote controller layout schemes exist according to different applications.
FIG. 1 is a layout of keys of a conventional remote controller; FIG. 2 is a key layout of the multi-purpose remote controller of the present invention.
A meter:
fig. 3 is a diagram of the meter structure of the present invention. The signal of the multi-purpose remote controller is firstly transmitted to the RF radio frequency receiving circuit 5, demodulated and transmitted to the mcu circuit 1, and the mcu circuit 1 decodes and transmits to the external interface 4 through the communication circuit 3. And finally, transmitting the data to the intelligent electrical appliance component according to the appointed communication protocol.
The decoding of the multi-purpose remote control signal can also be done by the connected intelligent electrical component, but this is too inefficient and increases the data communicated.
The mcu circuit 1 includes an mcu chip and peripheral circuits thereof. The mcu is an intelligent chip, has strong processing capacity and is responsible for the management of the whole instrument, including signal acquisition, ADC conversion, display driving of LCD/LED, communication, voice processing and the like.
The RF receiver circuit 5 may be a dedicated modular circuit, and is commercially available. A corresponding superheterodyne radio frequency receiving circuit can also be added on the instrument circuit board, and the network has a plurality of mature circuits. Generally divided into 315 or 433.
The technical parameters mainly considered for the type selection of the mcu are as follows: the operating speed, the temperature range, the quantity of GPIOs, the FLASH size, the RAM size, the mode of the external communication port and other parameters are considered. At present, a plurality of single-chip microcomputers in the market can meet the requirement, and for example, the single-chip microcomputers can be used in a plurality of brand technologies of manufacturers such as Microchip, freescale, ST, infineon, cypress and the like.
The communication circuit 3 differs according to different communication modes. The selectable communication modes are as follows: uart, lin, can, i2c, 485, gpio analog communications, etc. The communication is bidirectional, and in order to save cost, the invention recommends selecting a single-wire half-duplex mode, commonly called 'one-wire-line communication'.
In fig. 3, the mcu circuit 1 controls the voice chip circuit 2 to send out a weak voice signal, then the voice signal is amplified through the power amplifier circuit 6, and then the speaker 7 is driven to send out a sound through the external interface 4.
The type of the voice chip in fig. 3 is determined according to the amount of voice data to be stored and the requirement of voice quality, and the operating temperature range is also considered. The voice data is many, and the tone quality that requires is high, just needs to select the pronunciation chip of large capacity for use. Instead, a chip with a small capacity may be selected. The requirements of sound quality determine how much speech sampling rate is used and thus how much capacity is needed. Sampling rates of 8K, 16K, 32K are relatively common. At present, a plurality of voice chips can be realized in the market, most of the voice chips are produced in Taiwan province of China, and the voice chips with the specifications of 040, 060 and 080 are usually required. 040 means 40 seconds of storage space for speech, 060, 080 and so on.
The power amplifier circuit in fig. 3 amplifies the weak voice signal output by the voice chip 2 to a certain power, so as to drive the speaker to make a sound. The larger the sound required, the greater the power amplification. The structure of the power amplifier circuit is related to the output form of the voice chip 2 and the specification of the loudspeaker. Generally speaking, the voice output of the chip has two forms of DAC and PWM, and the sound playing device has a buzzer and a moving coil speaker, which results in various forms of the power amplifier circuit. Some circuits can be combined by common discrete devices, and triode circuits can be directly used for low power. Some power amplifier chips can be used, and LM386 can be selected for low power.
The loudspeaker 7 is generally selected as a buzzer horn and is connected with the power amplifier circuit 6 through the external interface 4.
The other functional circuitry 8 in fig. 3 also includes processing of a number of front vehicle appliances, including controller-associated appliances and non-controller-associated appliances.

And finally, transmitting the data to the intelligent electrical appliance component according to the appointed communication protocol.
The decoding of the multi-purpose remote control signal can also be done by the connected intelligent electrical component, but this is too inefficient and increases the data communicated.
