[0045] The technical solutions in the application will be described clearly and completely in combination with the drawings in the application. In addition, the forms of the structures described in the following embodiments are only examples, and the control method and system for brake temperature monitoring in the application are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the application.

[0046] As shown in the figure, the embodiment provides a control method for brake temperature monitoring, which comprises: Figure 1

[0047] S1: The preheating trigger threshold and the preheating delay time of the brake before braking are set based on the monitored environment temperature by monitoring the external environment temperature, the mechanical movement is determined by the preheating trigger threshold, and whether the brake abnormality occurs is determined by the preheating delay time.

[0048] ​In this embodiment, the S1 monitors the ambient temperature by using a temperature sensor, determines whether the ambient temperature is in a higher temperature state or a lower temperature state, and sets and adjusts the preheating delay time and the preheating trigger threshold of the brake according to the level of the ambient temperature; when the ambient temperature is lower, a longer preheating delay time and a higher preheating trigger threshold can be set according to the current ambient temperature; when the ambient temperature is higher, a shorter preheating delay time and a lower preheating trigger threshold can be set according to the current ambient temperature; when the preheating temperature reaches or exceeds the preheating trigger threshold, it is determined that the mechanical movement starts, the brake operation is performed, and it is further checked whether the brake abnormality occurs; after the mechanical movement starts, it is determined whether the brake abnormality exists according to the preheating delay time; if the preheating time of the brake exceeds the preheating delay time for too long, the brake has not reached the optimal working temperature after the mechanical movement starts, it is determined that the brake abnormality occurs, and an alarm is issued; if the preheating time of the brake is within the preheating delay time, the temperature collection and analysis of the brake during the brake operation under the corresponding temperature environment are performed.

[0049] It should be specifically noted that the preheating delay time refers to the time interval from the activation of the preheating trigger threshold to the actual preheating of the brake. The setting of this time interval needs to consider the preheating speed of the brake, the starting preparation time of the mechanical or vehicle, the reaction time of the driver, and other factors. A reasonable preheating delay time can ensure that the brake reaches the optimal working temperature before the mechanical or vehicle starts to move, thereby avoiding the brake abnormality. Through the monitoring and control of the preheating temperature, it is beneficial to prevent the problems of brake performance decline and material fatigue caused by excessive preheating.
