New description: [New technical field] This creation is about an AC motor anti-overheating device, especially the interaction between the temperature switch and the microprocessor, so that the creation can be prevented. Ma Gao uses the advantages of convenience. ^ [Prior Art] According to the electric roller door system, a motor is used to drive the roller shutters to rise and fall. For a long time, the use of the electric roller shutter will cause the motor temperature to rise; therefore, some of the electric roller door motors will automatically overheat. Protection switch. When the temperature of the motor rises above the normal operating temperature, the self-operating and superheating protection will automatically depend on the power supply flowing through the motor, and the motor will be suspended. After the motor temperature drops below the normal operating temperature, The automatic thermal protection switch will return to the power supply, so that the motor can work normally, and thereby achieve the purpose of protecting the motor. However, when the roll door horse 4 equipped with the automatic overheat protection switch drives the roll door action, the roll door may be suddenly interrupted during the opening or closing stroke, so that the roll door cannot be reached to the position, and the roll door action is made. Stop between the entire trip. As a result, the entry and exit of goods or people must be suspended, which in turn reduces the overall efficiency of the operation of the factory, and also causes inconvenience to users. In view of this, the creator's demand for automatic overheat protection switches based on electric iron shutters has accumulated experience in many years of design in this industry, and has created an AC motor anti-overheat detection device for use by the industry. . [New Content] 5 M319584 In view of the above-mentioned shortcomings of the prior art, the main purpose of the present invention is to provide an AC motor anti-overheat detecting device that prevents overheating of the motor and improves ease of use. In order to achieve the purpose and other purposes, the present invention provides an AC motor anti-overheat detection device for use in an AC motor, which controls the operation of the roll door, and includes a microprocessor, a relay group, a control interface and A temperature switch, wherein: the microprocessor is used for computing digital signals and controlling relay group operations, including an arithmetic unit for processing calculation and control routines, and a memory unit for storing programs and storing materials. ; The relay group is connected to the input end of the AC motor, and is electrically connected to the microprocessor, the microprocessor controls the relay group switching action, and the relay group controls the AC motor to rotate, reverse or stop; The utility model is electrically connected to the microprocessor for inputting a control signal to the microprocessor and controlling the rolling door action; the temperature switch is coupled to the temperature of the microprocessor motor. Money. Flow motor' (4) Sensing communication With the above technical means, this creation can heat up and improve the advantages of making the difference.敝n Preventing the motor from passing through [Embodiment] The technology, means and examples of the company are in line with the quality of the product. Please refer to the figure - figure and figure 2 for specific understanding. The device, the system should be arbitrage lang, _, ^ = this creation to find the horse overheat detection Haimo motor _ system control volume 901 action, 6 M319584 a control interface 3 and a temperature open contains a microprocessor oom, a Relay Group 2, Off 4 〇 'The above microprocessor 1 is used to calculate the digital signal and control the relay 2 action, - including the arithmetic unit and the control unit u, and _ use and storage data The fresh element 12, the fresh element 12 __ person - 赖 (2), the software 121 is used to determine the operation of the relay group 2 by the arithmetic unit π. The relay group 2 is connected to the wheel terminal of the AC motor _, and is electrically connected to the microprocessor 1, the microprocessor 1 controls the switching action of the relay group 2, and the relay group 2 is switched by the action. The control power source 902 flows through the AC motor 900 line, thereby controlling the AC motor 900 to rotate forward, reverse, or stop, and the AC motor 9 causes the roll door 9〇1 to rise, fall, or stop. The control interface 3 is electrically connected to the microprocessor 1 for inputting a control signal to the microprocessor 1 for operation and controlling the operation of the scroll gate 901. The temperature switch 4 is coupled to the microprocessor 1 and contacts the AC motor 9A to sense the temperature of the AC motor 900. When the temperature of the AC motor 900 exceeds the normal operating temperature, the temperature switch 4 A superheat signal is transmitted to the microprocessor 1; and when the temperature of the AC motor 9 is within the normal operating temperature, the temperature switch 4 transmits a normal signal to the microprocessor 1 to cause the shutter 901 to continue normal operation. ^ For the use of the above components, please refer to the first and second figures. The AC motor anti-overheat detection device of the present invention is mainly operated by the user when the temperature of the AC motor 900 is within the normal operating temperature. The control interface 3 causes the control interface 3 to input a control signal to the microprocessor 1 for operation.
