EH oil tank oil leakage early warning device

The utility model relates to an EH oil tank oil leakage early warning device. The EH oil tank oil leakage early warning device comprises an oil level detection sensor arranged on an EH oil tank; the analog quantity input point acquisition module is connected with the oil level detection sensor and is used for acquiring the oil level and outputting the oil level in real time; the controller is connected with the analog quantity input point acquisition module, receives the oil level output in real time from the analog quantity input point acquisition module, stores the oil level according to time, calculates a difference value between the oil level in preset time and the oil level in current time, and sends an alarm signal when the difference value exceeds a preset value; and the alarm is connected with the controller and is used for receiving the alarm signal to give an alarm. According to the scheme, early warning can be conducted on oil level descending of the EH oil tank, and unit safety is improved. 本实用新型涉
