Transmission protocol method of coal mine exploitation ground displacement and deformation PDA mobile equipment

The invention provides a transmission protocol method of coal mine exploitation ground displacement and deformation PDA mobile equipment. Data is safety transmitted between the PDA mobile equipment and a data center by means of an asymmetric encryption algorithm. The method comprises the following steps that: firstly, the data center provides a resource list to the PDA mobile equipment; then the PDA mobile equipment sends a request message to the data center according to protocol standards and is allowed to send data to the data center only after the message is verified; then the PDA mobile equipment sends registration information verification to the data center and is allowed to send a large amount of data to the data center only by the registration information verification; and finally, the PDA mobile equipment carries out primary arrangement and encryption on data according to coal mine exploitation subsidence information, the information after encryption is sent to the data center, then the data center re
