Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The motor torque force adjusting method according to the preferred embodiment of the present invention, as shown in fig. 1, comprises the following steps:
and S10, when door opening or closing actions are detected, setting motor torque parameters of the intelligent door lock to a preset gear.
Referring to fig. 2, a flowchart of step S10 in the motor torque adjustment method according to the present invention is shown.
As shown in fig. 2, the step S10 includes:
s11, when door opening or door closing actions are detected for the first time, judging whether motor torsion parameters are empty or not;
and S12, when the motor torque parameter is detected to be empty, setting the motor torque parameter to a preset gear.
Specifically, after the intelligent door lock is installed (for example, the intelligent door lock of the invention is installed on a door of a user, the intelligent door lock of the invention can be applied to various occasions needing to be installed, and is particularly suitable for occasions where a door is frequently opened and closed), an installer can trigger the intelligent door lock to automatically adapt to the flow of adjusting the torque parameters of a motor in a door opening or closing mode, and the state of a lock tongue can be detected only when the motor is operated during the door opening or closing.
Therefore, after the door opening action or the door closing action is detected for the first time, whether the motor torque parameter of the motor is empty or not is judged (namely, the motor torque parameter is not set at the moment, the aim of adjusting the motor torque is achieved through the motor torque parameter), when the motor torque parameter is detected to be empty at the moment, the motor torque parameter is set to a preset gear, for example, the preset gear is preferably the lowest gear, because the lower the gear of the motor torque parameter is, the lower the power consumption of the intelligent door lock is, the motor torque parameter is set to the lowest gear at the beginning, and when the lowest gear cannot meet the door opening and closing requirement, the gear of the motor torque parameter is gradually adjusted, and a plurality of gears can be preset. Further, when the motor torque parameter is detected to be not empty, the motor torque is adjusted according to the preset motor torque parameter, or the motor is directly operated according to the preset motor torque parameter, namely, the motor torque parameter is already set at the moment, the motor torque parameter is not required to be automatically adapted to be adjusted, namely, the motor torque parameter is used for operation.
The motor generally uses PWM (Pulse Width Modulation, pulse width modulation, which is an analog control method, to modulate the bias of the transistor base or the MOS transistor gate according to the change of the corresponding load, so as to change the on time of the transistor or the MOS transistor, thereby realizing the change of the output of the switching regulated power supply, which can keep the output voltage of the power supply constant when the working condition changes, is a very effective technique for controlling the analog circuit by using the digital signal of the microprocessor, and the pulse width modulation is a very effective technique for controlling the analog circuit by using the digital output of the microprocessor, and is widely used in many fields from measurement, communication to power control and conversion); therefore, the duty ratio of the signal waveform (the duty ratio refers to the proportion of the energizing time to the total time in one pulse cycle) is controlled, and the duty ratio is 100%, so that the power consumption is maximum, and the motor torque is also maximum; if the duty ratio is set to 0, the motor is equivalent to not working, and the power consumption is 0; theoretically, the duty cycle of different motor controls requires reference to a motor manual in combination with door lock design to determine a suitable range; the intelligent door lock manufacturer can divide the intelligent door lock into different gears according to the power consumption and the standby time requirements in the range; for example, common gears are: 50%,60%,70%,80%, etc.
Step S20, driving a motor to run, detecting the state of a lock tongue of the intelligent door lock, and when the state of the lock tongue is detected to be not in place, adjusting the torque parameter of the motor by one gear; when the state of the lock tongue is detected to be in place, the detection times are increased, and whether the detection times reach a preset threshold value is judged.
Specifically, when the motor torque parameter is set to the lowest gear, for example, the lowest gear of the motor torque parameter in the intelligent door lock is 50% (each gear corresponds to a specific motor torque parameter value), then the motor torque parameter is set to 50% at this time, after the lowest gear is determined according to the actual gear of the intelligent door lock, the driving motor starts to work (i.e. the driving motor starts to run), after the motor runs, the state of the lock tongue needs to be detected, wherein the lock tongue is a structure that the lock tongue pops out to be blocked in a hole reserved in the door frame when the door is closed, and the control door cannot be opened.
In the invention, the detection of the state of the lock tongue can be specifically realized by detecting the value fed back by the lock tongue sensor, for example, if the current full-automatic electronic lock body is designed with an in-place sensor (namely, the lock tongue sensor), the detection can be directly carried out according to the value returned by the lock tongue sensor, for example, the lock tongue can be considered in place when the value returned by the lock tongue sensor reaches a preset value (for example, the preset value is set to be 1), namely, the lock tongue is considered in place when the value returned by the lock tongue sensor is 1, or the lock tongue can be considered not in place when the value returned by the lock tongue sensor does not reach the preset value, for example, the lock tongue is considered not in place when the value returned by the lock tongue sensor is 2.
Further, for the intelligent door lock without in-place sensor (namely, a dead bolt sensor), the judgment can be carried out by feeding back a current signal through a motor according to the following principle: when the motor works, normal working current is known, when the motor stretches out and draws back to the right, if the motor is driven to stretch out and draw back continuously, the motor current exceeds the working current, namely the phenomenon of blocking rotation of the motor, whether the motor stretches out and draws back to the right can be judged by detecting the size of the blocking rotation current, and if blocking rotation occurs, the lock tongue is in place; otherwise, the motor is driven continuously, and the door lock circuit is required to increase the locked rotor current detection in the type of design.
According to the above method for detecting the state of the lock tongue, it can be judged whether the state of the lock tongue is in place (i.e. whether the lock tongue can be normally opened or closed), if the state of the lock tongue is not in place (e.g. the lock tongue does not reach a designated position when the lock tongue is closed or the lock tongue does not reach a designated position when the lock tongue is opened), that is, if the state of the lock tongue cannot be normally opened or closed, it is indicated that the motor torque parameter of the lowest gear is insufficient to drive the lock tongue to normally open or close the door, then the motor torque parameter needs to be adjusted, at this time, the motor torque parameter can be adjusted up by one gear, for example, when the lowest gear of the motor torque parameter in the intelligent door lock is 50%, the gear of the motor torque parameter in the intelligent door lock is adjusted up by 60%, after the gear of the motor torque parameter in the intelligent door lock is adjusted up by one gear, the motor is continuously driven, the state of the lock tongue is detected again, if the lock tongue is in place, if the state of the lock tongue is not in place, the state is not reached, the motor torque parameter in the up by one gear is continuously adjusted up to 70%, and the intelligent door lock is circulated until the lock tongue is reached.
In addition, when the state of the lock tongue is detected to be in place (for example, the lock tongue reaches a designated position when the lock is closed or the lock tongue reaches the designated position when the lock is opened), the lock can be normally opened and closed at the moment, and the lock can be driven by the torque force of the current motor to open and close the door, at the moment, although the setting of the torque force parameter of the motor can be represented as the normal opening and closing of the door, the setting of the torque force parameter of the motor can be represented, but the result of one test is only the result, and the authenticity and the reliability of data cannot be represented, so that in order to avoid such contingency, the invention verifies whether the torque force parameter of the current motor really meets the requirement by increasing the detection (test) times (sequentially increasing, each time of the detection) or not, and then after the detection times are increased, whether the detection times reach the preset threshold value needs to be judged.
Further, after the detection times are increased, whether the detection times reach a preset threshold value (for example, 5 times) is required to be judged, when the detection times do not reach the preset threshold value (for example, the detection times are 3 times, then the detection times do not reach 5 times), whether the action of the current end of the door lock is a door opening action is continuously judged, when the action of the current end of the door lock is judged to be a door opening action, the motor is controlled to execute a door closing action (only one switch can carry out complete test), and the motor is continuously driven to operate until the detection times reach the preset threshold value; when the door lock is judged to be in the closing state, the motor is controlled to execute the opening operation (only one switch can be used for complete testing), and the motor is driven to operate continuously until the detection times reach the preset threshold value.
And step S30, when the detection times reach a preset threshold value and the state of opening or closing the door each time is normal, setting the current motor torque parameter as a target parameter, and adjusting the motor torque by using the target parameter when opening or closing the door again.
Specifically, when the detection times reach a preset threshold value (for example, the detection times are 5 times, that is, the requirement of the detection times is met), and each time the door is normally opened or closed (that is, each detection can be completed, the door is normally opened or closed), the current motor torque is set as a target parameter (or called an optimal parameter), and the target parameter is obtained through multiple times of verification, and has reliability and stability; for example, after 5 times of detection, the door can be opened or closed normally, the gear of the current motor torque parameter is 60% (i.e. the motor torque is determined to be a value of 60%) and then the motor torque at that time is set as a target parameter, that is, the intelligent door lock is automatically adapted to select a proper motor torque parameter (i.e. the motor torque which is finally needed to be obtained), then when the door is opened or closed again, the target parameter is used as a default parameter of the motor torque, that is, after the default motor torque parameter is set, the door is opened or closed later, and then the target parameter (i.e. the default parameter) is used for working, thereby completing the automatic adaptation process of the motor parameter of the intelligent door lock.
The intelligent door lock can be divided into two types according to the starting mode of the motor: full-automatic intelligent lock, semi-automatic intelligent lock. The semi-automatic intelligent door lock is a door lock operated by manual operation and a machine device, and the starting of the semi-automatic intelligent door lock is that a motor drives a small clutch, but the door is still opened by manually twisting a handle. The full-automatic intelligent door lock is a mechanical device and the production process of the door lock is fully automated, the intelligent door lock has great requirements on a motor, great torsion is needed to ensure the normal unlocking of the intelligent door lock, the full-automatic intelligent door lock is driven by the motor to operate, the full-automatic intelligent door lock is not influenced by external force, and the intelligent door lock is preferably the full-automatic intelligent door lock.
According to the intelligent door lock, the intelligent door lock is triggered to automatically adapt to and adjust the motor torsion parameter in a door opening and closing mode, so that the intelligent door lock can work in an optimal parameter gear, the motor torsion parameter is automatically optimized, the intelligent door lock is ensured to always work in lower power consumption, the service time of a battery of the intelligent door lock is prolonged, the power consumption is saved, the service life of the intelligent door lock is prolonged, and meanwhile, the installation time of an installer and the capability requirement on the installer are reduced.
Further, as shown in fig. 3, the whole execution process of the torque parameters of the adaptive motor in the invention is as follows:
step S101, starting;
step S102, detecting a door opening action or a door closing action, and executing step S103 after detecting the door opening action or the door closing action;
step S103, judging whether the motor torque parameter is empty at the moment, executing step S105 when the motor torque parameter is empty, and executing step S104 when the motor torque parameter is not empty;
step S104, when the motor torque parameter is detected not to be empty, the motor torque is adjusted according to the preset motor torque parameter, namely, the motor torque parameter is already set at the moment, which means that after the intelligent door lock is installed, the intelligent door lock is not opened or closed for the first time, and then the motor torque parameter is not required to be automatically adapted and adjusted, namely, the motor torque parameter is used for working;
step S105, when the intelligent door lock enters an adaptive motor parameter setting process, that is, when a door opening or closing action is detected for the first time and a motor torque parameter is empty, setting the motor torque parameter to a preset gear (for example, a lowest gear);
step S106, the driving motor starts to work (namely, the driving motor starts to run);
step S107, detecting the state of the lock tongue after the motor runs, wherein the detection of the state of the lock tongue can be specifically implemented by detecting the value fed back by the lock tongue sensor, such as the detection principle described above;
step S108, judging whether the lock tongue is in place (namely, whether the door can be normally opened or closed), if yes, executing step S110, and if not, executing step S109;
step S109, when detecting that the state of the lock tongue is not in place (for example, the lock tongue does not reach a designated position when the door is closed or the lock tongue does not reach the designated position when the door is opened), that is, when the door cannot be opened or closed normally, the motor torque parameter of the lowest gear at the moment is not in accordance with the requirement, then the motor torque parameter needs to be adjusted, at the moment, the motor torque can be adjusted up by one gear (step by step up), and then the step S106 is executed continuously;
step S110, when detecting that the state of the lock tongue is in place (for example, the lock tongue reaches a designated position when closing the door or reaches the designated position when opening the door), the lock tongue can be normally opened and closed at the moment, and whether the torque parameter of the current motor really meets the requirement is verified by increasing the detection times for 1 time (namely, increasing the test times and sequentially increasing the test times and increasing one test time each time) in order to avoid the accidental occurrence of data;
step S111, judging whether the detection times reach a preset threshold value after the detection times are increased, if yes, executing step S115, and if not, executing step S112, wherein the proper range of the preset threshold value is 5-10 times, and the preset threshold value is preferably 5 times in the invention;
step S112, namely when the detection times do not reach the preset threshold value, judging whether the current action of the intelligent door lock is a door opening action, if yes, executing step S113, and if not, executing step S114;
step S113, when judging that the current door lock is closed, controlling the motor to execute the door closing action, and returning to execute step S106, namely continuing to drive the motor to run until the detection times reach a preset threshold value;
step S114, when judging that the current door lock is closed, controlling the motor to execute the door opening action, and returning to execute step S106, namely continuing to drive the motor to run until the detection times reach a preset threshold value;
step S115, when the detection times reach a preset threshold value and the state of opening or closing the door each time is normal, setting the current motor torque parameter as a target parameter, and then using the target parameter to adjust the motor torque when opening or closing the door again, namely after setting a default motor torque parameter, opening or closing the door later, and using the target parameter (such as an optimal parameter) to work, thereby completing the automatic adaptation process of the intelligent door lock motor parameter;
step S116, ends.
The process of automatic adjustment of the motor torque force is shown in the flow, when the door opening or closing action is detected for the first time and the motor torque force parameter is empty, the motor torque force parameter is set to be the lowest gear, if the motor torque force parameter of the lowest gear does not meet the requirement of opening or closing the door (judging according to the state of the lock tongue), the gear of the motor torque force parameter is gradually increased until the adjusted motor torque force parameter meets the requirement of opening or closing the door, the motor torque force parameter at the moment is the default parameter which is finally required to be obtained, the default parameter is finally determined to be the optimal parameter after the default parameter is detected for many times, then the optimal parameter is used as the default parameter of the motor torque force when the door is opened or closed again, and the adjustment of the motor torque force parameter is automatically completed, so that the intelligent door lock can work under the optimal parameter gear, thereby saving the power consumption and prolonging the service life of the intelligent door lock.
