The invention relates to a mental workload assessment method, device, equipment and medium. The method comprises the steps of firstly obtaining an electroencephalogram signal and an electrocardiosignal of a testee, then carrying out the feature extraction of the electroencephalogram signal to obtain a PSD feature, carrying out the feature extraction of the electrocardiosignal to obtain an HR feature and an HRV feature, and finally taking the electroencephalogram signal, the PSD feature, the HR feature and the HRV feature as model input, acquiring the mental load category of the testee by using the assessment model, so that the mental load category of the testee can be evaluated by integrating the electroencephalogram signal and the electrocardiosignal, and the evaluation precision can be remarkably improved. 本发明涉及一种脑力负荷评估方法、装置、设备、介质，先获取被测者的脑电信号和心电信号，然后对脑电信号进行特征提取，得到PSD特征，对心电信号进行特征提取，得到HR特征和HRV特征，最后以脑电信号、PSD特征、HR特征和HRV特征作为模型输入，利用评估模型得到被测者的脑力负荷类别，进而能够综合脑电信号和心电信号共同来评估被测者的脑力负荷类别，能够显著提高评估精度。
