The invention discloses a workbench operation authority control system based on a cloud platform; the workbench operation authority control system comprises the cloud platform, an electronic label carried by each worker, and a field detection module arranged on each workbench; the field detection module comprises a control module, and a card reader, a communication module and a workbench switch module respectively connected with the control module; the control module exchanges data with the cloud platform via the communication module; the cloud platform stores operation authority data of all workbenches, and sends the corresponding operation authority data to the control module on each workbench; the electronic label stores the data of the corresponding worker; the card reader reads the data stored in the electronic label in a communication range, and sends the data to the control module; the control module searches the corresponding operation authority from the memory, and drives theworkbench switch module to start corresponding functions of the workbench according to the operation authority. The control system can improve the workshop operation safety, and can use automatic control to improve the workshop management works with high efficiency.
