(1) Simulation test is the key link to find out whether there are problems in the examinee's computer equipment, mobile equipment and network environment and solve the problems. It takes sufficient time to solve the problem of equipment or network environment. Please take part in the simulation test carefully to confirm that all relevant equipment is normal. If the examinee does not participate in the mock test due to personal reasons, and the equipment or network environment problems are discovered before the formal examination or when taking the examination, resulting in the inability to participate or complete the examination normally, the examinee shall bear the responsibility. After the simulation test is successfully completed, it is suggested that the computer equipment should not be used for other purposes. Before the formal examination, please restart the software and ensure that the system does not sleep and the network is normal, and check the relevant equipment again.

(4) Candidates need to conduct simulation tests independently, and the network, equipment and environment used during the test are required to be consistent with the network, equipment and environment used by candidates during the formal examination.

In order to help candidates and parents better prepare for the environment and facilities required for the exam, we have arranged a simulation test in advance, mainly testing the test environment, equipment, system, network, identity verification, answer test and other processes.

Note: The simulation test is a key link to find out whether there are problems with the examinee's computer equipment, mobile equipment and network environment and solve the problems. It takes sufficient time to solve the problem of equipment or network environment. Please take part in the simulation test carefully to confirm that all relevant equipment is normal. If the examinee does not take part in the mock test due to personal reasons, and the equipment or network environment problems are discovered before the formal examination or when taking the examination, resulting in the inability to participate normally or to complete, the examinee shall be deemed to have automatically given up the interview qualification. After the simulation test is successfully completed, it is suggested that the computer equipment should not be used for other purposes. Before the formal examination, please restart the software and ensure that the system does not sleep and the network is normal, and check the computer equipment again.

The interview simulation test will be held on March 25. Each category simulation period is subject to the admission ticket. Candidates must conduct a simulation test before the test. The purpose of the simulation test is to be familiar with the answering environment and operation process, and to test reference equipment. If there is a problem with the reference equipment, replace it in time.

After the simulation test is opened, use the test equipment to directly open the browser to enter the test address, debug the camera, enter the ID number to log in, and enter the simulation test after confirming that the personal information is correct. There is a two-dimensional code of the invigilation system in the examination interface, which can be opened by scanning with independent monitoring equipment.

It can provide the following functions: constant current charging and discharging, constant power charging and discharging, constant voltage charging, constant current and constant voltage charging, constant load discharging, etc. DC internal resistance test; Auxiliary temperature test; Working condition simulation; Channel parallel output function; Integration of third-party equipment, such as temperature box, BMS, vibration table, vehicle controller, etc.; Sorting and matching function.

Candidates are required to prepare for the examination and monitor the equipment and network by themselves, and ensure that the installation and testing of the online examination system and invigilation APP are completed during the mock examination, so as to avoid installation or use problems during the examination that affect the normal examination;

During the formal examination, if the examination time is lost or the examination cannot be completed due to the failure of their own equipment or network, they will not be able to get the opportunity to make up and make up the examination, and the relevant consequences shall be borne by the examinee. Please be sure to take the simulation test and adjust the test equipment and network as required.

In order to ensure the effect of the simulation test, the simulation test link should be prepared for the examination equipment and environment according to the same requirements of the formal examination. Log in to APP to set up invigilation environment, confirm to invigilator that invigilation environment is qualified, and then log in to APP for simulation test. Candidates are required to take part in all three simulation tests in principle. If they do not take part in the simulation test due to personal reasons, resulting in incorrect operation during the formal examination and affecting the normal conduct of the examination, they shall bear the consequences.

After several rounds of tests such as simulation test, simulation test, examination system performance and functional test, the examination committee has been able to confirm that the performance and function of the examination system can better meet the needs of this examination.

The hardware of the test platform mainly includes upper computer, real-time simulator, battery simulator, signal auxiliary equipment and so on. Among them, the upper computer realizes the development and monitoring of simulation and test, and is the running platform of model development software, simulation control software and monitoring software. The real-time simulator realizes the real-time calculation of battery model and vehicle model, and sends the corresponding instructions and output expectations to the battery pack simulator through the communication module. The battery pack simulator simulates the output of each unit and sends the feedback simulation results to the simulator, at the same time, the simulator can simulate other modules of the vehicle through the signal conditioning box and interact with the BMS for data.

Candidates' self-test and simulation test are the key links to find out whether there are problems in the examinee's computer equipment, mobile equipment and network environment and solve the problems. It takes sufficient time to solve the problems of equipment or network environment. Please take part in the independent test and simulation test carefully to confirm that all relevant equipment for the test is normal! If the examinee does not take part in the preliminary relevant tests due to personal reasons, and the equipment or network environment problems are discovered before the formal examination or when taking the examination, resulting in the inability to participate or complete normally, the examinee shall bear the responsibility. After the simulation test is successfully completed, it is recommended not to use the computer equipment for other purposes. Before the formal examination, it is recommended to start the machine in advance and test the computer equipment again. If the examinee cannot take the examination normally due to non-system technical problems such as computer failure, network disconnection, power failure, account error, failure to take relevant tests on time, or if one item of video and audio is not uploaded normally, thus affecting the evaluation of written examination results, the examinee shall bear the responsibility.

Operation and maintenance monitoring: provides functions such as device control, API control, device log, alarm center, and remote upgrade.
