The method comprises the steps that a Tbox login event is sent to a server, the server receives detailed login parameters such as tuid and certificate certid after the request, the server initializes a socket client, finally the server sends a socket client starting request to a TSP platform, then the TSP platform returns a response of successfully establishing a channel to the server, the server generates a login message after receiving the response, and sends a request of sending the login message to the TSP platform, the platform returns an RSA secret key response, the server sends a confirmation of receiving the secret key response to the TSP, and the server sends a request to a portal, wherein the request comprises an uplink message returned according to the event and a downlink message returned according to the event.
Third, the event return message
The Portal simulates the selected event of the function to the server, the server searches the TlvModels of the function after receiving the request, so as to reply and return the TlvModels to the Portal according to the function, the Portal renders a form, the Portal sends simulation function parameters to the server to submit the event request, the server generates a TLV string according to the content of the form, processes the TLV string into a byte array and packages the byte array into a correct message body, the server sends the message after RSA encryption of the message body to the TSP platform after processing, the platform returns a message response to the server, and the server sends an uplink message returned according to the event and a downlink message returned according to the event to the Portal.
The system has a TLV message analysis function, analyzes the simulated vehicle state information, and then sends the analyzed information to the cloud. The vehicle state information comprises the running state, the driving mileage, the remote control instruction message, the positioning information and the alarm information of the vehicle.
Specifically, the cloud terminal is tested by logging in the simulation platform, simulating signal receiving and sending and uplink and downlink of event return.
And opening the tbox simulation platform, popping up a login page on the page, seeing that the page consists of characteristics, start work and historical records after login is successful, clicking a characteristic module to connect the tbox, and selecting a version, an environment, a tuid and a protocol to finish the login simulation platform.
After login is successful, the page is successfully jumped to a starting work page, the starting work page consists of four plates with active reporting, query instruction response, control instruction response and other functions, corresponding instructions are found in an active reporting module to be sent, for example, a transmitter is ignited, an engine instruction message is sent through simulation, corresponding instruction message types are found through sid and mid, content is calculated through a checking tlv table, the content of the content has byte length, the traditional binary message is converted into a hexadecimal message according to an agreed protocol, and the hexadecimal message is sent out through a simulation platform.
After the message for sending the instruction is submitted successfully, the message type, the uploading message and the issuing message can be seen, whether the message is sent successfully or not is judged through the information, and when the message for pre-issuing the uploading message is received successfully, the simulation platform sends the instruction successfully.
The simulation platform simulates the message of the event instruction, completely simulates the instruction message sent out in the real vehicle operation process, improves the test efficiency and truly restores the real vehicle use scene.
The test method can conveniently execute the test case, simulate different signals to be uploaded and transmitted and received, pull the corresponding message in tbox compliance detection, and then compare the message with expected data.
