when there is a request for disconnection from a client (i.e., d-client) in the list, the device deletes the connection information of the client (i.e., d-client) in the list (abd).
S2: and establishing connection among the clients (taking fig. 1 as an example, establishing connection among the client a, the client b and the client c).
Specifically, step S2 includes:
s21: each client (namely, a client, b client and d client) acquires a list (abd); specifically, when the device replies the broadcast or the message to the client, the device sends a list to the client at the same time;
s22: each client (namely, a client, b client and d client) establishes connection with other clients except the client in the list (abd); specifically, the client receives the reply information of the device and also receives the list, so that connection can be established with other clients except the client in the list through the connection information recorded in the list;
s23: when the list (abd) is changed, the equipment sends the changed list (abc) to the clients (namely, a client, b client and c client) in the changed list (abc);
s24: each client (namely, the client a, the client b and the client c) receives and establishes connection with other clients except the client in the list (abc) according to the changed list (abc).
S3: when any client sends an instruction to the device, synchronous data is sent to other clients at the same time (taking fig. 1 as an example, when a client sends an instruction to the device, synchronous data is sent to b client and c client at the same time).
Specifically, step S3 includes:
s31: a, a client receives an input instruction of a user;
s32: the client (i.e. a client) judges whether the input command belongs to the equipment control command, if not, the operation is finished, and if so, the operation continues to the step S33; the equipment control instruction specifically refers to a parameter instruction for controlling the working state of the equipment and an operation instruction for controlling the working process of the equipment;
s33: the clients (i.e., a-clients) send input instructions to the device while sending input instructions to other clients (i.e., b-clients and c-clients) in the list (abc) except for themselves.
Some parameter instructions and operation instructions are finished instantly by directly clicking, and the probability of simultaneous operation and conflict among different clients is relatively low; some parameter instructions and operation instructions are completed by inputting contents such as numerical values and the like, a certain time is needed, and the probability of simultaneous operation and conflict among different clients is relatively high and needs to be overcome; for this, step S3 further includes:
s301: when the user selects a certain command input box for inputting a command, the client (i.e. a client) judges whether the command input box belongs to the device control command input box, if not, the process is finished, if yes, the process continues to step S302;

s303: the client (namely, the b client and the c client) receives input box locking instructions sent by other clients (namely, the a client) except the client in the list (abc);
s304: the client (namely, the b client and the c client) locks the specified instruction input box according to the received input box locking instruction.
The locking is that the instruction input box cannot be selected, or the instruction input box can be selected but cannot input an instruction, or the instruction input in the instruction input box cannot be confirmed or executed. The method comprises the steps of realizing the locking of the instruction input box, and the following steps of realizing the unlocking of the instruction input box:
s305: when the instruction input box selected by the user in step S302 ends the selection state, the client (i.e., the a client) sends an input box unlocking instruction to other clients (i.e., the b client and the c client) in the list (abc) except for itself; the instruction input box ending selection state may specifically be that the user cancels selection of the instruction input box or completes input in the instruction input box;

The reason for displaying the locking can be that a remark symbol is displayed, a remark symbol is opened to explain the specific reason, or 'X user is operating' is directly displayed; displaying the locking reason can facilitate the expansion of the locking function of the instruction input box, and the instruction input box can be locked in other states needing locking, such as: after the parameter instruction is sent, the instrument needs to adjust the working state, and at the moment, if the working parameter of the equipment is modified again, the equipment is easy to cause equipment failure, so that the instruction input box can be designed to be locked in the state; when the user operates the device, the user can know whether the instruction input box is locked because other users operate the device or the device is in a parameter adjusting state.
S4: any client side receives the synchronization data sent by other client sides and then synchronizes the data (taking fig. 1 as an example, the client side b and the client side c receive the synchronization data sent by the client side a and then synchronize the data).
