A method for controlling and managing a field device using an industry Internet operating system comprising at least an industry cloud server and industry field devices, the method comprising: receiving, by an industry field device, a device identifier configuration strategy issued by the industry cloud server, establishing a communication connection with another industry field device according to the device identifier configuration strategy, and further generating a list of device information; wherein the industry field device is a master device, another industry field device is a slave device, and the slave device is controlled by the master device; wherein the establishing a communication connection with another industry field device according to the device identifier configuration strategy, and further generating the list of device information comprises: receiving, by the master device, a device identifier request sent by the slave device on its own initiative upon being powered on, wherein the device identifier request comprises at least device information of the slave device; allocating, by the master device, a device identifier for the slave device according to the device information, and sending the device identifier to the slave device, so that the slave device is registered, and acknowledges, using the device identifier; and generating, by the master device, the list of device information according to the device identifier and the device information; and sending, by the master device, the list of device information to the industry cloud server on its own initiative, so that the industry cloud server controls the slave device according to the list of device information; wherein controlling by the industry cloud server, the slave device according to the list of device information comprises: receiving, by the master device, an upgrade command sent by the industry cloud server for the slave device; wherein the upgrade command comprises a device type, and a version number; determining, by the master device, at least one corresponding slave device to be upgraded according to the upgrade command and the list of device information; sending, by the master device, the upgrade command to the at least one corresponding slave device to be upgraded, so that the at least one corresponding slave device to be upgraded upgrades in response to the upgrade command; and updating, by the master device, the list of device information corresponding to the at least one slave device to be upgraded. receiving, by an industry field device, a device identifier configuration strategy issued by the industry cloud server, establishing a communication connection with another industry field device according to the device identifier configuration strategy, and further generating a list of device information;
