Problems solved by technology

When there is a big difference between the safety value and the output force value, if there is a foreign object stuck on the moving door or window, the window drive or door opener will continue to increase the force value output. When the output force value is close to the safety value and has not touched the safety value, the output The force value may cause irreversible mechanical deformation or personal injury, but the window drive or door drive does not stop working. The larger the range of the safe value, the greater the safety hazard.
When the difference between the safety value and the output force value is very small, it is easy to cause false triggering because the output force value and the safety value are too close

Embodiment 1

[0046] When a foreign object is stuck on the door and window during operation, the force to prevent the movement of the door and window increases instantly. Once the situation exceeds the safety limit, the window or door opener will be slowed down, stopped or executed in reverse operation mode to avoid Causes mechanical irreversible deformation and personal injury, and executes the action when the foreign object is removed.

Embodiment 2

[0048] When the temperature is less than or equal to 0°C, the doors and windows may be frozen. When the window or door opener detects that the ambient temperature is less than or equal to 0°C, and the operating force value of the window or door opener exceeds the safety limit, the normal operation is stopped, and the method of repeatedly vibrating the doors and windows and starting and running alternately is used to solve the problem. Windows and doors are frozen.

Embodiment 3

[0050] During the use of doors and windows, the track of the switch may become lubricated or astringent or other changes over time. The window opener or door opener of the present invention records the data of each action, removes the jump data, and The data that occurs normally is subjected to micro-weighted superposition, and the basic data is formed through micro-weighted superposition. According to the basic data, the safety limit greater than or equal to the basic data is obtained by processing the basic data, which is used as the safety limit of the window or door operator. Thereby reducing the wear and tear of the machine during use and prolonging the service life.

Abstract

The invention discloses a calculating method of a window opener or door opener operation safety limiting value. Based on known actual operation data in a window opener or door opener operation process, a safety limiting value which is greater than or equal to the actual operation data is calculated. The actual operation data in a window opener or door opener stroke comprises initial data when a window opener or a door opener leaves a factory and an operation force value after usage. In the initial data, initial force value data is directly detected through a torque sensor; an initial current or a voltage or power data can be directly detected through a current sensor or a voltage sensor; and the power data can be acquired through calculation and is stored in a control module. By using the method, a difference value between the actual operation data and the safety limiting value keeps in a fixed range so that mechanical and unrecoverable deformation and a personal injury are not generated; and simultaneously, a condition that false triggering is generated because of an extraneous influence is avoided.

Description

technical field [0001] The invention relates to the field of window openers or door openers, in particular to a calculation method for operating safety limits of the window opener or door opener. Background technique [0002] With the improvement of people's living standards, more and more factories and smart homes use smart window or door opening systems. The intelligent window or door opening system is connected with the window or door opener controller through a centralized controller, which can realize manual and automatic opening and closing of doors and windows. The controller of the window or door opening machine is the actuator of the intelligent window or door opening system, and its performance determines the cost and reliability of the window or door opening system. [0003] There are currently three types of motion states for window or door openers in the technology: open state, closed state, and soft slow stop state. Set a fixed value of safety value for each s...
