Problems solved by technology
[0003] At present, the motors on the market have the problem of stroke loss. After power failure, the stroke cannot be saved, resulting in stroke loss and errors. The reason is that there is no reference object for the stroke after power-on, and the single-chip microcomputer has no comparison, so it cannot be recognized and the stroke is lost.

Embodiment 1
[0051] see figure 1 , an automatic repair method for electronic limit travel, comprising the following steps:
[0052] Step 1. When the power is turned on again after an abnormal power failure, the motor starts to run, and the motor is controlled by a single-chip microcomputer, and a logic language is programmed into the single-chip microcomputer;
[0053] Step 2. When the itinerary is not lost, that is, the set point of the itinerary is normal, you can continue to work. When the itinerary is lost, you need to confirm the lost itinerary, set the itinerary point, and then continue to work;
[0054] Step 3. First, the single-chip microcomputer controls the buzzer on the motor to turn on, and the motor rotates forward. The buzzer is connected to the single-chip microcomputer through a signal. The buzzer is used to remind the staff that the motor is confirming the lost trip;
[0055] Step 4: When the movement reaches the mechanical limit point 1 and is stopped, it is recorded as ...

The present invention discloses an automatic repairing method of an electronic position-limiting travel distance, pertaining to the field of automatic equipment. According to the automatic repairing method of the electronic position-limiting travel distance, when a system is powered on again after abnormal power failure occurs, a motor starts to operate, if the travel distance is not lost, i.e., the setting point of the travel distance is normal, the system can continue to work; and if the travel distance is lost, the lost travel distance is need to be determined firstly, and the travel distance point(s) are set. A single chip computer controls a buzzer on the motor to start, the motor rotates forwardly, the motor is stopped until the motor moves to a mechanical position-limiting point, afirst travel distance is recorded, and meanwhile the single chip computer controls the motor to rotate reversely. According to the method, when the system is powered on again after the abnormal powerfailure occurs, the motor operates towards one direction firstly until the motor is stopped, the stopped position is recorded as one travel distance point; and then the motor operates towards the other direction until the motor is stopped, and the other travel distance point is recorded. The distance between the two position-limiting points is one travel distance, and thus the effect of determining the lost travel distance is realized.
Description
technical field [0001] The invention relates to the field of automation equipment, and more specifically, to an automatic repair method for electronic limit travel. Background technique [0002] Automation (Automation) refers to the machine equipment, system or process (production, management process) without the direct participation of people or fewer people, according to people's requirements, through automatic detection, information processing, analysis and judgment, manipulation and control, to achieve the expected target process. Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services and households. The use of automation technology can not only liberate people from heavy physical labor, part of mental work, and harsh and dangerous working environments, but also expand human organ functions, greatly improve labor productivity, and enhance human ability to understand and transform the...
