Terminal over-temperature early warning method and device, meter box equipment and storage medium

The invention provides a terminal over-temperature early warning method and device, meter box equipment and a storage medium. The method comprises the following steps: determining a target voltage error value of a line where target equipment is located; if the target voltage error value is greater than or equal to a preset error threshold value, determining the terminal contact resistance of the target equipment according to the target voltage error value; determining a predicted terminal temperature of the target device according to the terminal contact resistance; and if the predicted terminal temperature is higher than the early warning temperature value, early warning information is sent. By applying the method in the meter box equipment, the working safety of the meter box equipment can be improved. 本申请提供一种端子过温预警方法、装置、表箱设备及存储介质。该方法可以包括：确定目标设备所在线路的目标电压误差值；若目标电压误差值大于或等于预设误差阈值，则根据目标电压误差值确定目标设备的端子接触电阻；根据端子接触电阻确定目标设备的预测端子温度；若预测端子温度高于预警温度值，则发送预警信息。通过在表箱设备中应用该方法，可以提高表箱设备工作的安全性。
