一种防止液体加热设备干烧的控制方法和系统
摘要：
本发明提供一种控制方法和控制系统，不断检测液体加热设备中的温度变化并计算出温度增加速率，将其与所设定阈值比较来判断是否发生干烧。为了避免因水位波动等因素造成的误检测，本发明通过连续三次采集的数据来判断是否出现干烧的情况。同时可通过LED显示灯向用户发出故障警示，提醒用户检查热水器和管路。本发明通过温升的速度来判断液体加热设备中是否发生干烧，来保护电加热，提高设备的使用寿命，为液体加热设备的使用提供安全保障，避免发生安全事故。
摘要（英）：

The invention provides a control method and a control system, which can continuously detect temperature change in liquid heating equipment and calculate out temperature increasing rate. The temperature increasing rate is used for comparing with a set threshold value to judge whether parching happens. In order to avoid mistaken errors caused by factors of water level fluctuation and the like, the control method and the control system can collect data continuously for three times to judge whether parching happens. Simultaneously, light-emitting diode display lamps are utilized to give fault alarm to users to remind users of examining a water heater and a pipeline. The control method and the control system can judge whether parching happens according to speed of temperature rise in the liquid heating equipment to protect electrical heating, prolong service life of equipment, provide safety guarantee for using the liquid heating equipment and prevent safety accidents from happening.
