说明书摘要
Summary of the instruction manual

做为感应垃圾桶在使用过程中，人们希望开盖速度快，关盖速度缓慢。开盖速度快便于人们快捷扔掉手中的垃圾，关盖速度缓慢是为了减少桶盖与桶体的碰撞声响。但在桶盖缓慢关闭动作过程中，人们再想扔垃圾就要等到桶盖关闭动作到位后才能再次感应开盖，如果在关盖动作过程中采取不断的发射红外线脉冲信号对感应区测试是否有障碍物，当测试到有障碍物时，桶盖就无需等到关闭到位就重新开启，就可以解决上述问题。但由于关盖动作过程中电机处于通电状态，通电状态下的电机会对有微弱信号放大的红外线脉冲测试电路产生强烈的干扰。本专利的技术手段是在关盖动作过程中：当需要发射红外线脉冲信号对感应区测试时，暂停对电机的供电，在完成发射红外线脉冲信号对感应区测试后，再恢复对电机的供电，由于发射红外线脉冲信号对感应区测试的时间极短，对桶盖关闭动作过程的机械惯性影响极小，不影响桶盖关闭过程的连续性。
As an induction trash can, in the process of use, people want to open the lid quickly and close the lid slowly. The fast opening speed makes it easy for people to quickly throw away the garbage in their hands, and the slow closing speed is to reduce the sound of the collision between the lid and the barrel. But in the process of slow closing action of the barrel lid, people want to throw away garbage again to wait until the lid is closed in place before the lid can be opened again, if in the process of closing the lid to take the continuous emission of infrared pulse signal to the induction area to test whether there is an obstacle, when the test has an obstacle, the barrel lid does not need to wait until the closure is in place to re-open, can solve the above problem. However, due to the fact that the motor is in a power-on state during the cover closing action, the motor in the power-on state will have a strong interference with the infrared pulse test circuit with weak signal amplification. The technical means of the patent are in the process of closing the cover: when it is necessary to transmit infrared pulse signal to test the induction area, suspend the power supply to the motor, and then resume the power supply to the motor after completing the test of the induction area of the emitting infrared pulse signal, because the time of emitting infrared pulse signal to the induction area test is extremely short, The mechanical inertia of the lid closure process has little effect on it, and does not affect the continuity of the lid closure process.

本发明专利涉及一种主动反射式红外线感应垃圾桶关盖动作控制方法，尤其涉及一种感应垃圾桶关盖动作过程再感应开盖的控制方法。
The invention patent relates to an active reflective infrared induction trash can lid closure action control method, in particular to a control method for sensing the trash can lid closing action process and then inducting the lid opening.

背景技术
Background technology

现有市场上的感应垃圾桶，绝大部分都采用红外线反射式技术做为传感器，在使用过程中，人们希望开盖速度快，关盖速度缓慢。开盖速度快便于人们快捷扔掉手中的垃圾，关盖速度如果太快，桶盖在关闭动作过程中容易碰到人的手，同时在桶盖关闭动作到位时桶盖与桶体的碰撞声响也会比较大声，影响使用者对产品的体验感，所以人们更喜欢桶盖缓慢关闭的垃圾桶，但在桶盖缓慢关闭过程中，人们如果想再次扔垃圾就要等到桶盖关闭到位后，才能再次感应开盖扔垃圾，如果在关盖动作过程中采取不断的发射红外线脉冲信号对感应区测试是否有障碍物，当测试到有障碍物时，桶盖就无需等到关闭到位就能重新感应开启桶盖，就可以解决上述问题。但由于关盖动作过程中电机处于通电状态，通电状态下的电机会对有微弱信号放大的红外线脉冲测试电路产生强烈的干扰，致使红外线脉冲测试电路无法正常工作，难以实现上述功能，本专利的技术手段就是要解决上述问题。
Most of the induction trash cans on the existing market use infrared reflective technology as a sensor, and in the process of use, people want to open the lid quickly and close the lid slowly. If the closing speed is too fast, the lid is easy to touch people's hands during the closing action, and the collision sound between the lid and the barrel body will be louder when the lid is closed in place, which affects the user's experience of the product, so people prefer the garbage can with the lid slowly closed, but in the process of slow closure of the barrel lid, if people want to throw garbage again, they have to wait until the lid is closed in place before they can open the lid and throw garbage again. If the in-depth infrared pulse signal is continuously emitted during the closing of the lid to test whether there is an obstacle in the sensing area, when the obstacle is detected, the barrel lid can be re-opened without waiting until it is closed in place, which can solve the above problems. However, because the motor is in the energized state during the closing action, the motor in the energized state can produce strong interference with the infrared pulse test circuit with weak signal amplification, so that the infrared pulse test circuit can not work normally, and it is difficult to realize the above-mentioned function, and the technical means of the patent are to solve the above-mentioned problem.

本专利的目的在于解决现有技术不足之处，提供一种感应垃圾桶关盖动作时再感应开盖的控制方法，能够克服电机在关盖过程中对有微弱信号放大的红外线脉冲测试电路产生强烈的干扰。实现桶盖无需等到关闭到位就能重新感应开启的方法，同时，不影响桶盖关闭过程的连续性与顺畅感。
The object of the patent is to solve the deficiencies of the prior art, and provide a control method for inducting the lid to open again when the lid is closed by induction, which can be overcomeDuring the closing process, the motor produces strong interference with the infrared pulse test circuit with weak signal amplification. It is possible to re-open the lid without waiting for it to be closed in place, without affecting the continuity and smoothness of the lid closing process.

本专利的目的是通过以下途径来实现的：
The purpose of this patent is to be achieved by:

感应垃圾桶关盖动作时再感应开盖的控制方法，包括红外线脉冲测试电路、微电脑控制器、电机驱动电路、电机、减速器和桶盖，在感应垃圾桶桶盖关闭动作过程中，由微电脑控制器控制红外线脉冲测试电路，每间隔一段时间或每间隔一段行程向感应区发射红外线脉冲信号，如果测试到感应区无障碍物，微电脑控制器通过电机驱动电路控制电机带动桶盖继续完成关闭动作；如测试到感应区有障碍物，微电脑控制器通过电机驱动电路控制电机反向转动，使桶盖立即开启。当每次发射红外线脉冲信号对感应区测试时，先暂停对电机的供电，待发射红外线脉冲信号对感应区测试完成后，立即恢复对电机的供电，在关盖动作过程，累计发射红外线脉冲信号对感应区测试的时间远小于桶盖关闭动作过程的时间。
The control method of induction trash can lid opening when the lid is closed, including an infrared pulse test circuit, a microcomputer controller, a motor drive circuit, a motor, a reducer and a barrel lid, in the process of induction trash can lid closing, the infrared pulse test circuit is controlled by a microcomputer controller, If the test is found that there is no obstacle in the sensing area, the microcomputer controller controls the motor to drive the barrel cover to continue to complete the closing action through the motor drive circuit; If there is an obstacle in the sensing area, the microcomputer controller controls the motor to rotate in reverse through the motor drive circuit, so that the barrel lid is opened immediately. When each time the infrared pulse signal is emitted to the induction zone test, the power supply to the motor is suspended first, and the power supply to the motor is restored immediately after the infrared pulse signal is tested to the induction zone after the emission of the infrared pulse signal is completed.

进一步具体为，在关盖过程中，每隔10ms～300ms发射1次红外线脉冲信号对感应区测试，每次发射红外线脉冲信号对感应区测试的时间小于或等于0.3ms。比如桶盖的关盖动作时间为4秒(4000ms)，每次发射红外线脉冲信号对感应区测试的时间为0.3ms，按最小间隔时间每10ms发射1次红外线脉冲信号计算：4000ms的关盖动作时间总共发射400次红外线脉冲信号对感应区测试，累计发射红外线脉冲信号对感应区测试的时间=400次×0.3ms=120ms，120ms的电机累计停止时间远小于桶盖缓慢关闭过程4000ms的时间，而每个周期的电机停止时间为0.3ms，电机的每个周期通电占空比=10ms÷(10ms+0.3ms)=97%，电机通电的高占空比，对于桶盖、减速器、电机的转子都是有重量惯性的物体，所以对桶盖关闭过程的机械惯性影响极小，能保证桶盖关闭过程的连续性与顺畅感。
Further specifically, in the process of closing the cover, every 10ms~300ms every 10ms~300ms emitting an infrared pulse signal to test the sensing area, each time the infrared pulse signal is emitted to test the sensing area for less than or equal to 0.3ms. For example, the closing time of the barrel lid is 4 seconds (4000ms), the time of each infrared pulse signal to the sensing area test is 0.3ms, and the infrared pulse signal is emitted once every 10ms according to the minimum interval time: the closing time of 4000ms is emitted a total of 400 times The infrared pulse signal is tested on the sensing area, and the cumulative time of emitting infrared pulse signals for the sensing area test = 400 times× 0.3ms = 120ms, the cumulative stop time of the motor of 120ms is much less than the time of 4000ms in the slow closing process of the barrel cover, and the motor stop time of each cycle0.3ms, the energized duty cycle of the motor = 10ms÷ (10ms + 0.3ms) = 97%, the high duty cycle of the motor energized, for the barrel cover, reducer, and the rotor of the motor are objects with weight inertia, so the mechanical inertia of the barrel lid closing process has little impact, and the continuity and smoothness of the barrel lid closing process can be ensured.

进一步具体为，在关盖过程中，每隔关盖总行程的0.5%～10%发射1次红外线脉冲信号对感应区测试，其每次发射红外线脉冲信号对感应区测试的时间小于或等于0.3ms。比如桶盖的关盖动作时间为3秒(3000ms)，每次发射红外线脉冲信号对感应区测试的时间为0.3ms，按最小行程每0.5%总行程间隔发射一次红外线脉冲信号计算：关盖总行程共发射200次红外线脉冲信号对感应区测试，累计发射红外线脉冲信号对感应区测试的时间=200次×0.3ms=60ms，60ms的电机累积停止时间远小于桶盖缓慢关闭过程3000ms的时间，电机的通电总占空比=(3000ms-60ms)÷3000ms=98%，电机通电的高占空比，对于桶盖、减速器、电机的转子都是有重量惯性的物体，所以对桶盖关闭过程的机械惯性影响极小，能保证桶盖关闭过程的连续性与顺畅感。
Further specifically, in the process of closing the cover, every 0.5%~10% of the total stroke of the cover is emitted once an infrared pulse signal is tested on the induction area, and the time of each infrared pulse signal emitted to the induction area test is less than or equal to 0.3ms. For example, the closing time of the barrel lid is 3 seconds (3000ms), the time of each infrared pulse signal to the sensing area test is 0.3ms, and the infrared pulse signal is emitted once every 0.5% of the total stroke interval of the minimum stroke: the total stroke of the lid is emitted 200 times of infrared pulse signal to the sensing areaTest, the cumulative time of emitting infrared pulse signals to the induction area test = 200 times×0.3ms = 60ms, the cumulative stop time of the motor of 60ms is much less than the time of 3000ms in the slow closing process of the barrel cover, and the total duty cycle of the motor = (3000ms-60ms) ÷3000ms=98%, the high duty cycle of the motor is energized, and the rotor of the barrel cover, reducer and motor are all objects with weight inertia, so the mechanical inertia of the barrel lid closing process has little impact, which can ensure the continuity and smoothness of the barrel lid closing process.

与现有技术相比，本专利具有以下优点：在桶盖的缓慢关闭过程中，不断的发射红外线脉冲信号对感应区测试，当人的手或障碍物重新进入感应区，桶盖就无需等到关闭到位就重新开启，完全克服了电机通电时对红外线脉冲测试电路的干扰，即实现了关盖动作过程中也能重新扔垃圾的功能，又克服了桶盖关闭动作过程中容易碰到人手的问题，同时也保证了缓慢关盖动作过程中的连续性与顺畅感。具有很强的实际应用价值和产品的体验感。
Compared with the prior art, the patent has the following advantages: in the slow closing process of the barrel lid, the infrared pulse signal is continuously emitted to test the induction area, when the human hand or the obstacle re-enters the induction area, the barrel cover does not need to wait until it is closed in place to re-open, completely overcomes the interference of the infrared pulse test circuit when the motor is energized, that is, the function that the lid can be re-thrown in the process of closing the lid, and the problem that it is easy to touch the human hand in the process of closing the lid is overcome again, At the same time, it also ensures continuity and smoothness during the slow closing of the cap. It has a strong sense of practical application value and product experience.

参见图3波形图，在关盖动作过程中，本具体实施例每隔50ms发射1次红外线脉冲信号对感应区1进行测试，每次发射红外线脉冲信号对感应区1测试的时间为0.3ms。桶盖7的关盖动作时间为3秒(3000ms)，3000ms的关盖动作时间总共发射60次红外线脉冲信号对感应区1测试，累计发射红外线脉冲信号对感应区1测试的时间=60次×0.3ms=18ms，18ms的电机5累计停止时间远小于桶盖7缓慢关闭过程3000ms的时间，而每个周期的电机5暂停时间为0.3ms，电机5的每个周期通电占空比=50ms÷(50ms+0.3ms)=99.4%，电机5通电的占空比高达99.4%，对于桶盖7、减速器6、电机5的转子都是有重量惯性的物体，所以对桶盖7关闭过程的机械惯性影响极小，能保证桶盖7关闭动作过程的连续性与顺畅感。
Referring to the waveform diagram of Fig. 3, in the process of closing the cover, the present embodiment transmits an infrared pulse signal every 50ms to test the sensing area 1, and the time of each emitting an infrared pulse signal to the sensing area 1 is 0.3ms. The closing action time of barrel lid 7 is 3 seconds (3000ms), and the closing action time of 3000ms emits a total of 60 infrared pulse signals to test the sensing area 1, and the cumulative time of emitting infrared pulse signals to the testing of the sensing area 1 = 60 times ×0.3ms=18ms, the cumulative stopping time of motor 5 of 18ms is much less than the time of 3000ms of the slow closing process of barrel cover 7, and the suspension time of motor 5 of each cycle is 0.3ms, the energized duty cycle of motor 5 = 50ms÷ (50ms + 0.3ms) = 99.4%, the duty cycle of motor 5 energized is as high as 99.4%, for barrel cover 7, reducer 6, The rotor of the motor 5 is an object with weight inertia, so the influence on the mechanical inertia of the barrel cover 7 closing process is very small, and the continuity and smoothness of the barrel cover 7 closing action process can be guaranteed.
