Perform parameter estimation calculations based on the personal abilities of the test personnel, and transmit the calculation results to server 1 for storage;

The process of receiving another subject’s answer information and personal information transmitted by the server on the client, performing parameter estimation calculations on the personal ability of the other subject, and transmitting the calculation results to the server is also the process between the client and the server. In the process of communication, the manner in which the client communicates with the server is as follows:

Step 1-1: the client computer and the server are connected through the Internet, the client computer and the PCs installed in the Internet are connected based on the handshake protocol, and the PCs and multiple servers are connected based on the handshake protocol;

Step 1-2: The client selects the server as the destination from several servers for communication purpose, and transmits the information to be communicated and the information of the server as the destination to the PC; the client first selects the server from multiple servers. The server as the destination party serves as the communication destination, and then the client sends a communication request to the PC, and after receiving a certain response, constructs a temporary storage space for information, and transfers the information to the PC by means of communication based on the handshake protocol; PC The computer performs a correctness check on the information transmitted by the client computer, and after confirming that it is correct, the client computer transmits the instruction information that the communication is correct to the PC;

Step 1-3: If the number of destination servers is not less than the first critical number or the information capacity is not less than the second critical number, go to step 1-4 for execution, that is, use the group sending mode; if the number of destination servers If it is not greater than the first critical number or the information capacity is not greater than the second critical number, go to steps 1-7 for execution, that is, use the one-to-one communication mode;

Steps 1-4: the PC divides the obtained information into several first information frames, processes the information frames into information frames based on the no-handshake protocol, and then sends them to the server as the destination;

The information is sent to all the servers on the Internet as the destination party through group sending based on the mode of no handshake protocol. Only the servers on the Internet as the destination party can send information from the network adapter to the upper level;

Before transmitting information, the server must know the basic information of communication, including information capacity, information readable and writable authority, information name, pointer to information storage, destination address of group sending, identification code of group sending, which can be divided into several times Sending from the PC can also be sent at one time; after the server receives the above information, it will sequentially implement operations such as information construction, authority check, pointer check, and name check, so as to realize concurrent operations between the PC and the server;

The PC divides all the information into several write-in spaces according to the capacity of the temporary storage space. The information in each temporary storage space is sequentially encapsulated according to the capacity of the information part of the information frame based on the handshake protocol. The handshake protocol information frame is transmitted to all servers in the known Internet as the destination in the mode of group transmission;

Steps 1-5: The server as the destination checks whether the information frame received based on the no-handshake protocol is missing information, and transmits the missing information to the PC; the PC thus obtains the number of missing information, if The number of lost information is not less than the third critical number, just go to step 1-4 and continue to send out information frames based on the no-handshake protocol; The server as the destination party with lost information retransmits the information corresponding to the lost information to the corresponding server as the destination party according to the one-to-one mode based on the handshake protocol;

Step 1-6: The server checks the information frame based on the no-handshake protocol. If there is no problem with the check, it will terminate. If there is a problem with the check, the server will respond to the error information frame of the PC, and the PC will make an error. The information frame based on the no-handshake protocol is transmitted to the server again relying on the one-to-one communication mode based on the handshake protocol;

Under the condition that all servers have no missing information, the transmitting party transmits the verification code to request each destination party to check the information in the temporary storage space; if there is no problem in the verification, the transmitting party obtains and transmits other residual information until the information is all During the transmission and inspection period, the information frame corresponding to the error message is transmitted to the server as the destination party again according to the one-to-one communication mode based on the handshake protocol;

Steps 1-7: The PC transmits the obtained information to each server according to the one-to-one communication mode based on the handshake protocol, thereby terminating the operation.

The beneficial effects of the present invention are:

The one-to-one communication mode realizes the communication between one client and one server alone, and the information accuracy is good. When the number of servers is small or the information capacity is not large, the one-to-one communication mode is used and the temporary storage waiting period is short. The mass sending mode realizes the communication between a client and several servers, which is transmitted synchronously and at a high speed. Timeliness is better achieved when there are many servers or the information capacity is not small, but the information generated by the broadcast is correct. Sexual deficiencies are addressed via the retransmission model in the following manner. The first critical number and the second critical number are measurement numbers, which can be flexibly configured depending on measurement data. The server continuously receives information frames based on the no-handshake protocol, and performs missing information verification and missing information detection processing on the information frames. The server always detects the state of the received information frame based on the no-handshake protocol, writes the information content contained in the information frame based on the no-handshake protocol into the temporary storage space for receiving, and refreshes the temporary storage space for receiving; After the transmission of the temporarily stored information is completed, the receiving end needs to check in real time which information in the temporary storage space has not been refreshed, that is, which information frame based on the no-handshake protocol is lost during the transmission period of the temporary storage space to the temporary storage space In this way, the PC, which constructs its own information loss temporary storage space, inquires the receiving status of each third intelligent terminal in turn after the information communication in a temporary storage space is completed, and retransmits the lost information according to the retransmission. The server passes the missing information to the PC. The PC sends the information frame corresponding to the lost information to the server again relying on the one-to-one communication mode. For the missing information, use the one-to-one communication mode to prevent the defect of incorrect information generated by group sending. Under the action of the air flow in the open-air environment, the annular collar W12 will be pushed to rotate, and the collar W12 will rotate under the cabinet W1 via the slewing support W9, and will synchronously pull the fins W11 rotates in the cabinet W1, so that the airflow can flow to the server through the louver W2 to cool the server, which can help to cool the gateway server under the condition of saving power, and the structure is not complicated. It is beneficial to combine the function of gas flow in the open-air environment, saving electricity and not polluting the environment; if the cabinet W1 shakes, the vertical rod W7, the sleeve W6 and the spiral glass bronze wire W8 can interact with each other. Combined with the reciprocating motion of the helical glass bronze wire W8 under pressure to reduce shock, reduce the adverse effect on the gateway server; the cover plate is good for drainage and can prevent the upper end from being angular and in the server cabinet The consequences of being damaged by lightning strikes often occur outside the room.

The beneficial effect of this embodiment is:

The one-to-one communication mode realizes the communication between one client and one server alone, and the information accuracy is good. When the number of servers is small or the information capacity is not large, the one-to-one communication mode is used and the temporary storage waiting period is short. The mass sending mode realizes the communication between a client and several servers, which is transmitted synchronously and at a high speed. Timeliness is better achieved when there are many servers or the information capacity is not small, but the information generated by the broadcast is correct. Sexual deficiencies are addressed via the retransmission model in the following manner. The first critical number and the second critical number are measurement numbers, which can be flexibly configured depending on measurement data. The server continuously receives information frames based on the no-handshake protocol, and performs missing information verification and missing information detection processing on the information frames. The server always detects the state of the received information frame based on the no-handshake protocol, writes the information content contained in the information frame based on the no-handshake protocol into the temporary storage space for receiving, and refreshes the temporary storage space for receiving; After the transmission of the temporarily stored information is completed, the receiving end needs to check in real time which information in the temporary storage space has not been refreshed, that is, which information frame based on the no-handshake protocol is lost during the transmission period of the temporary storage space to the temporary storage space In this way, the PC, which constructs its own information loss temporary storage space, inquires the receiving status of each third intelligent terminal in turn after the information communication in a temporary storage space is completed, and retransmits the lost information according to the retransmission. The server passes the missing information to the PC. The PC sends the information frame corresponding to the lost information to the server again relying on the one-to-one communication mode. For the missing information, use the one-to-one communication mode to prevent the defect of incorrect information generated by group sending. Under the action of the air flow in the open-air environment, the annular collar W12 will be pushed to rotate, and the collar W12 will rotate under the cabinet W1 via the slewing support W9, and will synchronously pull the fins W11 rotates in the cabinet W1, so that the airflow can flow to the server through the louver W2 to cool the server, which can help to cool the gateway server under the condition of saving power, and the structure is not complicated. It is beneficial to combine the function of gas flow in the open-air environment, saving electricity and not polluting the environment; if the cabinet W1 shakes, the vertical rod W7, the sleeve W6 and the spiral glass bronze wire W8 can interact with each other. Combined with the reciprocating motion of the helical glass bronze wire W8 under pressure to reduce shock, reduce the adverse effect on the gateway server; the cover plate is good for drainage and can prevent the upper end from being angular and in the server cabinet The consequences of being damaged by lightning strikes often occur outside the room.
