Intelligent electronic equipment data transmission method, device and system and medium

The embodiment of the invention discloses an intelligent electronic equipment data transmission method, device and system and a medium. The method comprises the steps that an intelligent electronic device IED verifies a confirmation message sent by an uplink access device, and after the verification is passed, power operation data of the IED is encrypted through a private key corresponding to the IED to obtain encrypted data; the IED transmits the data to an uplink access device; and the uplink access equipment obtains the private key corresponding to the IED, and decrypts the received data through the private key to obtain the power operation data. According to the technical scheme provided by the embodiment of the invention, the security of the data transmission process of the intelligent electronic equipment can be ensured, and the data is prevented from being stolen or tampered. 本发明实施例公开了一种智能电子设备数据传输方法、装置、系统及介质。其中，该方法包括：智能电子设备IED对上行接入设备发送的确认消息进行校验，并在校验通过后，通过IED对应的私钥将IED的电力运行数据进行加密，得到加密后的数据；IED将数据传输至上行接入设备
