具体实施方式Detailed ways

以下结合附图和具体实施例对本发明创造作进一步详细说明。The invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

一、智能判别红外防撞功能失效单元设计1. Intelligent identification of infrared anti-collision function failure unit design

由于引起红外防撞检测装置出现误判的原因很多，例如红外防撞检测装置本身出现故障，雨雪、异物对红外防撞检测的干扰等，其中有些故障只是暂时的，因此需要对故障状态进行智能判别，并根据判别结果进行相应的处理；当检测到故障时单元会使红外防撞功能自动处于失效，并控制电动伸缩门的正常使用；而当检测到故障恢复正常时单元会使红外防撞功能自动恢复到有效。There are many reasons for the misjudgment of the infrared anti-collision detection device, such as the failure of the infrared anti-collision detection device itself, the interference of rain, snow, and foreign objects on the infrared anti-collision detection, etc. Some of the faults are only temporary, so it is necessary to check the fault status. Intelligent discrimination, and corresponding processing according to the discrimination results; when a fault is detected, the unit will automatically disable the infrared anti-collision function, and control the normal use of the electric telescopic door; The bump function automatically returns to valid.

二、电机软启动控制单元设计2. Design of motor soft start control unit

在硬件电路上设计了电机软启动控制电路，利用对交流工作电压波形进行跟踪检测，并对启动控制电路进行单元控制，实现了电机启动时的软启动；从而大大降低了电机的启动电流，减小了电机启动时对电网的冲击，消除了门体起启时的抖动，使门体运行更加平稳。The soft start control circuit of the motor is designed on the hardware circuit, and the soft start of the motor is realized by using the tracking and detection of the AC working voltage waveform and the unit control of the start control circuit; thus greatly reducing the starting current of the motor and reducing the It reduces the impact on the power grid when the motor starts, eliminates the vibration when the door body starts, and makes the door body run more smoothly.

三、红外防撞检测装置和限位检测的电源控制单元设计3. Design of power control unit for infrared anti-collision detection device and limit detection

根据电动无轨伸缩门的使用特点，利用对红外防撞检测装置和限位检测电路的电源进行单元控制，实现在停机状态下(通常电动伸缩门大部分时间处于停止状态)红外防撞检测装置和限位检测电路的电源处于关闭状态；这样就解决了红外发射管长时间处于发射状态而导致的红外防撞检测装置过早报废的问题；同时在停止状态下由于电源的关闭，从而大大降低了集成控制盒的整机功耗。According to the use characteristics of the electric trackless telescopic door, the infrared anti-collision detection device and the power supply of the limit detection circuit are used for unit control to realize the infrared anti-collision detection device and The power supply of the limit detection circuit is turned off; this solves the problem of premature scrapping of the infrared anti-collision detection device caused by the infrared emission tube being in the emission state for a long time; at the same time, due to the power off in the stop state, it greatly reduces The overall power consumption of the integrated control box.

四、智能自动纠偏单元设计4. Design of intelligent automatic deviation correction unit

门体驱动采用双电机同步工作方式，在门体运行轨迹上预埋磁导航标识；并采用多个传感器检测磁导航信息。当门体运行时多个传感器将检测到的磁导航信息传送给单片机，根据这些信息计算出门体偏离正确轨迹的偏差值，并控制双电机间歇工作时间的长短，使门体逐渐返回到正确的运行轨迹上，从而实现智能自动纠偏功能。The door body drive adopts the dual motor synchronous working mode, and the magnetic navigation mark is pre-embedded on the door body running track; and multiple sensors are used to detect the magnetic navigation information. When the door body is running, multiple sensors transmit the detected magnetic navigation information to the single-chip microcomputer, and calculate the deviation value of the door body from the correct track according to these information, and control the length of the intermittent working time of the dual motors, so that the door body gradually returns to the correct track. On the running track, so as to realize the function of intelligent automatic deviation correction.

对于不同的引起红外检测装置功能失效的故障要深入研究，并针对不同的失效情况采取相对应的控制方式，以保证电动伸缩门正常运行。电动无轨伸缩门上通常采用双红外防撞检测装置进行红外防撞检测的，如果其中一个有故障时，不应影响另一个的正常检测；如果二个都有故障时，电动无轨伸缩门也能正常使用。其具体技术特征在于：Different faults that cause the failure of the infrared detection device should be studied in depth, and corresponding control methods should be adopted for different failure situations to ensure the normal operation of the electric telescopic door. Double infrared anti-collision detection devices are usually used on electric trackless telescopic doors for infrared anti-collision detection. If one of them is faulty, it should not affect the normal detection of the other; Normal use. Its specific technical features are:

控制盒接收到关门命令时，首先会检测二个红外防撞检测装置的输出电平，当其中一个或二个红外防撞检测装置的输出电平为低时，初步认为有以下几个情况发生，一是电动无轨伸缩门机头前(红外检测头前)有障碍物；二是红外检测头前异物遮挡；三是红外防撞检测装置出现故障。When the control box receives the door closing command, it will first detect the output levels of the two infrared anti-collision detection devices. When the output level of one or two infrared anti-collision detection devices is low, it is preliminarily considered that the following situations occur , First, there are obstacles in front of the electric trackless telescopic door (in front of the infrared detection head); second, foreign objects in front of the infrared detection head are blocked; third, the infrared anti-collision detection device fails.

为了判别低电平是否为故障引起的，控制电机反转，让电动伸缩门处于开门状态，开门3秒后自动停止；此时会继续检测二个红外防撞检测装置的输出电平，如果其中一个或二个红外防撞检测装置的输出电平仍为低时，说明红外防撞装置有故障或者红外检测头前异物遮挡，将该红外防撞检测装置标记为故障状态；如果其中一个或二个红外防撞检测装置的输出电平为高时，说明原来电动伸缩门机头前(红外检测头前)确实有障碍物，将该红外防撞检测装置标记为正常状态。In order to judge whether the low level is caused by a fault, control the reverse rotation of the motor to keep the electric retractable door in the open state, and automatically stop after opening the door for 3 seconds; at this time, it will continue to detect the output levels of the two infrared anti-collision detection devices. When the output level of one or two infrared anti-collision detection devices is still low, it means that the infrared anti-collision device is faulty or the foreign object in front of the infrared detection head is blocked, and the infrared anti-collision detection device is marked as a fault state; if one or two When the output level of an infrared anti-collision detection device is high, it means that there is indeed an obstacle in front of the electric retractable door machine head (in front of the infrared detection head), and the infrared anti-collision detection device is marked as a normal state.

当红外防撞检测装置的工作状态判定后，将继续执行关门命令；控制电机正转，让电动伸缩门处于关门状态；同时不停地检测标记为正常状态的红外防撞检测装置的输出电平；如果电平由高变成低时，说明电动伸缩门机头前(红外检测头前)有障碍物，此时控制电机反转，让电动伸缩门处于开门状态，开门3秒后自动停止，实现红外防撞功能。对于标记为故障状态的红外检测装置，在关门期间程序将不在对其输出电平进行检测，并使其红外防撞功能自动处于失效，这样就能够使电动伸缩门正常使用。When the working state of the infrared anti-collision detection device is determined, it will continue to execute the door closing command; control the motor to rotate forward, so that the electric retractable door is in the closed state; at the same time, it will continuously detect the output level of the infrared anti-collision detection device marked as normal ; If the level changes from high to low, it means that there is an obstacle in front of the electric telescopic door machine head (in front of the infrared detection head). At this time, the control motor is reversed to keep the electric telescopic door in the state of opening the door, and it will automatically stop after 3 seconds. Realize infrared anti-collision function. For the infrared detection device marked as a fault state, the program will not detect its output level during the door closing period, and its infrared anti-collision function will be automatically disabled, so that the electric retractable door can be used normally.

在每一次的关门命令执行时，首先会对二个红外防撞检测装置的输出电平进行检测，如果原来标记为故障状态的红外防撞检测装置的输出电平恢复到高电平，说明该装置恢复正常，该红外防撞检测装置标记为正常状态，并使其红外防撞功能自动恢复到有效。如果原来标记为故障状态的红外防撞检测装置的输出电平仍为低电平，说明该装置仍处于故障状态，该红外防撞检测装置继续标记为故障状态，并使其红外防撞功能继续失效。When the door closing command is executed each time, the output levels of the two infrared anti-collision detection devices will be detected first. If the output level of the infrared anti-collision detection device marked as a fault state returns to a high level, it means that the When the device returns to normal, the infrared anti-collision detection device is marked as a normal state, and its infrared anti-collision function is automatically restored to be effective. If the output level of the infrared anti-collision detection device originally marked as a fault state is still low, it means that the device is still in a fault state, and the infrared anti-collision detection device continues to be marked as a fault state, and its infrared anti-collision function continues invalidated.

上述智能红外防撞方法，具有很重要的应用价值和经济价值。The above intelligent infrared collision avoidance method has very important application value and economic value.
