Description
Technical Field
The invention relates to the field of wireless remote control, in particular to a remote control module powered by a storage battery and a control method.
Background
For a long time, no matter in industrial production or in residential consumption occasions, wireless remote control equipment or toys are often seen, and many remote control receiving modules installed inside the wireless remote control equipment or toys are powered by various storage batteries.
In the using process, the wireless receiving module needs to keep a monitoring state all the time, and the whole circuit system can continuously consume electric energy. In some use occasions, under the condition that the system cannot be shut down in time due to negligence of a user and the like, the whole system may consume the electric energy of the storage battery in a short time, so that the remote control is out of control.
The above problems are more obvious in the general power product industry, because the starting battery needs to bear the functions of starting the engine unit while bearing the power supply to the remote control module, once a user shuts down the machine without cutting off the power supply of the remote control module, the time is 2-3 days in short time and 1-2 weeks in long time, and the engine unit can not be normally started in a remote control mode due to the battery feed.
Aiming at the problems, in the current market, a starting battery of a universal power product with a remote control function, such as a gasoline-diesel generator set, basically uses a large-capacity lead-acid storage battery, but the generator set without the remote control function is switched into a small-capacity lithium battery, and even the large-capacity lead-acid storage battery only prolongs the standby time of a remote control module from 2-3 days to 1-2 weeks, so that the delay effect is not obvious, the remote control module is realized by depending on the increase of the battery capacity, and the problems of cost increase, environmental protection and the like are caused.
For the purpose of low power consumption, several other solutions exist in the prior art, such as:
the Chinese patent with the patent number discloses a low-power consumption digital signal wireless doorbell, which comprises a battery, a loudspeaker for receiving an output signal to sound, and a super-regenerative receiving digital signal amplifying circuit for receiving a signal from an antenna; a digital signal amplifying and shaping circuit for amplifying and shaping the output signal of the super-regenerative receiving digital signal amplifying circuit; a digital signal decoding circuit for decoding the digital signal output from the digital signal amplifying and shaping circuit; a music trigger circuit for receiving the signal of the digital signal decoding circuit and outputting a music signal by triggering according to the signal; the battery provides power for the digital signal amplifying and shaping circuit, the digital signal decoding circuit, the music triggering circuit and the loudspeaker; a switch circuit is arranged between the super-regeneration receiving digital signal amplifying circuit and the battery, the control end of the switch circuit is connected with a digital signal decoding circuit, and the digital signal decoding circuit outputs a digital signal to the control end of the switch circuit. In this way, the super-regenerative receiving digital signal amplifying circuit is in an intermittent working state, partial power consumption is reduced, but circuits or elements such as a decoding circuit, a music trigger circuit, a loudspeaker and the like are directly connected with a battery, and standby power consumption is generated all the time.
Patent No. 201110066162.1 provides an ultra-low power consumption wireless remote-measurement remote-control system and method, which is to let the controlled end normally stay in an ultra-low power consumption state for listening to signals after waking up periodically. When a working instruction needs to be sent to the controlled end, the control end continuously and uninterruptedly sends an instruction signal to the controlled end within a short period of time, and the controlled end only receives a data signal of 1 bit or a limited number of bits and checks the radio frequency characteristics, particularly the spread spectrum coding characteristics, of the data signal at the awakening moment. And only after the radio frequency characteristics are matched, the whole data signal packet is received and analyzed in a delayed mode. The scheme can greatly reduce the power consumption of the controlled end. However, the application scenario of the above scheme is relatively complex, the number of system components is large, the signal receiving and judging method is complex, and only the controlled end is subjected to low power consumption control, specifically, a single chip microcomputer or a GPS or other devices are not mentioned for performing low power consumption control on other power consumption modules.

Detailed Description
In order to better understand the technical content of the present invention, specific embodiments are described below with reference to the accompanying drawings.
In this disclosure, aspects of the present invention are described with reference to the accompanying drawings, in which a number of illustrative embodiments are shown. Embodiments of the present disclosure are not necessarily intended to include all aspects of the invention. It should be appreciated that the various concepts and embodiments described above, as well as those described in greater detail below, may be implemented in any of numerous ways, as the disclosed concepts and embodiments are not limited to any one implementation. In addition, some aspects of the present disclosure may be used alone, or in any suitable combination with other aspects of the present disclosure.
The embodiment is specifically a scheme for improving the power consumption of the remote control module in the standby state, and is implemented by combining two aspects of a software program preset in the MCU6 and a hardware circuit design of the remote control module. The software program presets the MCU6 in an intermittent low power consumption state and a normal power consumption state, and the whole power consumption of the energy-saving remote control module is weak in the low power consumption state, so that the power consumption can be reduced to the maximum extent only by reasonably setting the time of the low power consumption state and considering energy saving and normal operation. Meanwhile, energy conservation is also considered in the design of a hardware circuit, and when the MCU6 is in a low power consumption state, the power supply module 1 is in zero power consumption, so that the energy conservation effect is good.
Specifically, referring to fig. 1, an energy-saving remote control module according to an embodiment of the present invention is specifically a remote control module applied to a gasoline-diesel generator set, and the remote control module is required to be used as a receiving end to receive a remote control instruction on one hand, and to perform an action according to the remote control instruction on the other hand.
The energy-saving remote control module is powered by a power supply module 1 and comprises a digital control switch 2, a power consumption module and other control modules 8.
The power supply module 1 is used for supplying power to a power consuming module and simultaneously undertakes, for example, starting an engine, so that such a module usually needs a power supply with a larger voltage to complete starting an engine group, and a 12V power supply is generally adopted in the prior art, so that a 12V power supply is also adopted in this embodiment.
The power consumption module comprises a wireless receiving module 7 and an MCU 6. And the wireless receiving module 7 is used for receiving a wireless control signal and transmitting the wireless control signal to the MCU 6. The working state of the MCU6 is switched between a low power consumption state and a normal power consumption state according to a preset mode; the MCU6 is used to receive the wireless control signal transmitted by the wireless receiving module 7 and perform corresponding actions, and is used to control the digital control switch 2 to switch off when the MCU6 is going to enter a low power consumption state, and switch on when the MCU6 is going to enter a normal power consumption state.
The digital control switch 2 is arranged between the power supply module 1 and the power consumption module, and is used for controlling whether a circuit between the power supply module 1 and the power consumption module is conducted or not.
The other control modules 8 are mainly modules controlled by the MCU6, and as shown in fig. 1, the positions of the other control modules are set according to the functions of the other control modules, some of the other control modules need to be powered on all the time and are directly connected to the power supply module 1, and some of the other control modules can be powered on intermittently and are connected to the power supply module 1 through the digital control switch 2. These other control modules 8 also consume power, and the other control modules 8 provided behind the digital control switch 2 can realize energy saving control in the same manner as the above power consuming modules.
The number of the digital control switches 2 includes but is not limited to 1, for example, in this embodiment, 1 digital control switch 2 is adopted, in other embodiments, a plurality of digital control switches 2 in parallel may be provided, and different digital control switches 2 control different other control modules 8 and power consuming modules.
Specifically, the MCU6 performs initialization configuration and is in a standby mode after being powered on, and thereafter operates according to the following steps:
step one, the MCU6 is in a normal power consumption state, detects whether a wireless control signal sent by the wireless receiving module 7 is a valid characteristic signal, and enters a step two if the valid characteristic signal is not received within the time of opening delay T1; otherwise, the third step is entered.
The valid characteristic signal can be set as required, including but not limited to the high and low level characteristic pulse width of the remote control data signals '0' and '1' or the normal frame of remote control data or some section thereof.
In the second step, the MCU6 enters a low power consumption state with a time delay of T2, and then returns to the first step.
Thirdly, the MCU6 continuously monitors whether the wireless control signal sent from the wireless receiving module 7 is a valid control command, if the valid control command is received within the monitoring delay time T3, executes the command and determines whether the standby mode needs to be exited, and if the standby mode needs to be exited, the fourth step is performed; if no valid control command is received within the listening delay T3, the second step is entered.
Fourthly, the MCU6 exits the standby mode to continuously monitor, decode and execute the commands sent from the wireless receiving module 7, until the command to be standby is monitored and executed, for example, when the wireless receiving module is turned off, the MCU6 enters the standby mode and then enters the second step.
In the process, during the time of turning on the delay T1, the MCU6 consumes power normally, the digital control switch 2 is turned on, and the wireless receiving module 7 works normally; during the turn-off delay T2, the MCU6 has low power consumption, the digital control switch 2 is switched off, and the wireless receiving module 7 is powered off and does not work. In order to realize energy saving and normal operation, the ratio of T1 to T2 is set to be less than 1 to 10.
Since the working voltages of the wireless receiving module 7 and the MCU6 are both 3.3V, which is much lower than the 12V voltage of the power supply module 1, a voltage dropping module 3 and a diode are required to be disposed between the digital control switch 2 and the power consuming module for dropping the voltage of the power supply module 1 and supplying the voltage to the power consuming module.
As shown in fig. 1, the diode is disposed between the voltage step-down module 3 and the power consuming module, specifically, the first diode 41 is disposed between the voltage step-down module 3 and the MCU6, and the conducting direction of the first diode is from the voltage step-down module 3 to the MCU6, and the second diode 42 is disposed between the voltage step-down module 3 and the wireless receiving module 7, and the conducting direction of the second diode is from the voltage step-down module 3 to the wireless receiving module 7.
Both diodes here have the effect of further voltage reduction in conjunction with the voltage reduction module 3, the voltage reduction module 3 being responsible for reducing the voltage from 12V to 4V, the diodes being responsible for reducing the voltage from 4V to 3.3V. In particular, the first diode 41 also has the function of preventing backflow, and due to the unidirectional conduction function of the first diode 41, when the capacitor 5 is fully charged, only the MCU6 is supplied, so as to ensure that the power stored in the capacitor 5 can ensure that the MCU6 can work for as long as possible after the digital control switch is turned off.
More specifically, a capacitor 5 is connected in parallel between a power supply pin of the MCU6 and a negative power supply, the capacitor 5 obtains power supply from the power supply module 1 during normal operation of the MCU6, so that a certain amount of power is stored in the capacitor 5, when the MCU6 enters a low power consumption state, the amount of power stored in the capacitor 5 is used to power the MCU6 to maintain its low power consumption state until it is switched to a normal power consumption state, and then the digital control switch 2 is turned on to power the entire remote control system and supplement power to the capacitor 5 with its power supply pin connected in parallel.
As a more preferable embodiment, the digital control switch 2 is further provided with a power-on trigger circuit 11, which is used for generating a pulse signal at the power-on instant of the whole module to trigger the digital control switch 2 to be turned on, so as to activate the whole system to start working. The power-on trigger circuit 11 is specifically composed of passive devices such as a resistor and a capacitor 5, the technology is the prior art in the field, and the specific scheme can be freely designed by technicians, which is not described herein.
It should be noted that, when the MCU6 is in a low power consumption state, the power-on trigger circuit still has a small leakage current, and therefore consumes a small amount of power of the power module 1, but the influence of the leakage current is negligible due to the weak current.
Further, the power supply device further comprises a mechanical switch 10, and the mechanical switch 10 is disposed between the power supply module 1 and the digital control switch 2. The mechanical switch 10 is used for operator operation, and complete power-off is achieved by the mechanical switch 10 when necessary.
As shown in fig. 2, the energy-saving remote control module is used to perform energy-saving control, and after the digital control switch 2 is turned on, the output of the wireless receiving module 7 is detected, and when a wireless control command is detected, other control units of the system are controlled according to the control command.
Specifically, at the moment of power-on, the power-on trigger module generates a pulse signal to control the digital control switch 2 to be switched on, and after the MCU6 is powered on, the setting of the IO port, the control of switching on the digital control switch 2, the configuration of the timer, the setting of the standby flag FD to 1, the setting of the on delay T1 of the standby digital control switch 2, the setting of the off delay T2 of the standby digital control switch 2, the setting of the standby control command, the monitoring of the delay T3, the zero clearing timer, and other system parameter initialization operations are successively completed.
After the system initialization configuration is completed,
step 1: the MCU6 starts to detect that the wireless receiving module 7 outputs '0' or '1' characteristic signals; when the timer count value is greater than or equal to T1, and a valid wireless signature has not been detected,
step 2: the MCU6 executes a zero clearing timer, starts a delay awakening function, turns off the digital control switch 2 and enters a low power consumption mode; when the timer value is equal to or greater than T2,
and 3, step 3: the MCU6 automatically wakes up, clears the timer and repeats steps 1-3.
When the MCU6 receives a '0' or '1' wireless signature signal,
and 4, step 4: clearing the timer and continuously monitoring the output of the decoding wireless receiving module 7;
when the value of the timer is greater than or equal to T3 and the MCU6 does not monitor a valid control command, the step 2 is entered;
when a valid control command is monitored, whether the standby mode needs to be exited or not is judged according to the specific command after the command is executed, and if the command is a command for starting a machine or the like, the standby mode is entered
And 7, step 7: the whole system exits the standby mode (FD ═ 0) and continuously listens, decodes and executes the commands output by the wireless receiving module 7. When a shutdown command, such as a command requiring subsequent standby, is monitored, the whole control system enters into the system after the shutdown command is executed
And 8, step 8: resume standby mode (FD ═ 1) and execute step 2.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
