Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, an intelligent controller for an electronic stop board environment according to an embodiment of the present utility model includes a central controller 10, and PWM fan speed regulators 20, 24V relays 30, 220V relays 40, a temperature detection module 50, a 12V power output interface 60, and a 5V power output interface 70 electrically connected to the central controller 10, where the model of the central controller is PIC16F1615, the central controller 10 receives a temperature signal collected by the temperature detection module 50, and when the temperature is lower than a low temperature threshold, the 220V relays are turned on to control a heating module to increase the temperature; when the ambient temperature gradually approaches the high temperature threshold value, a 24V relay is started to control the PWM fan speed regulator to regulate the speed.

In a specific application example of the utility model, the temperature is regulated and controlled in real time according to the collected implementation temperature. For example, when the acquired real-time temperature is T and the high-temperature threshold temperature is-t= >10 degrees, the 24V relay control terminal is closed, and the fan rotation speed is 0. When the acquired real-time temperature is T, the temperature of 5 DEG < = high temperature threshold value temperature-T is less than 10 DEG, the control end of the 24V relay is started, and the rotating speed of the fan is 50% of the maximum rotating speed. When the acquired real-time temperature is T and the 0-DEG C < = high-temperature threshold temperature-T <5℃, the control end of the 24V relay is started, and the rotating speed of the fan is 80% of the maximum rotating speed. The collected real-time temperature is T, and when the high-temperature threshold temperature T is less than 0, the rotating speed of the fan is 100%. Through the arrangement, the speed regulation of the PWM fan speed regulator is divided into four gears, namely, 0 rotational speed gear, 50% rotational speed gear, 80% rotational speed gear and 100 rotational speed gear, so that the temperature can be reduced and the electricity can be saved through the regulation of the rotational speed of the PWM fan.

Through the electronic stop board environment intelligent controller, the detected temperature threshold is divided into a high temperature threshold and a low temperature threshold, and the threshold temperature is compared with the temperature detected in real time so as to control the rotating speed of the relay switch and the PWM fan, so that the temperature can be reduced and the electricity can be saved through the adjustment of the rotating speed of the PWM fan.
