The first embodiment is as follows:
a fuel cell system based testing method, see fig. 1, comprising the steps of:
receiving a test selection instruction input by a management user;
analyzing the test mode in the test selection instruction;
when the test mode is automatic test, executing a preset automatic test flow;
when the test mode is manual test, analyzing test contents in the test selection instruction;
when the test content is parameter setting, executing a preset manual parameter setting process; the manual parameter setting process is used for receiving a setting instruction input by a management user and setting the parameters of the fuel cell system according to the setting instruction;
when the test content is a debugging subsystem, executing a preset subsystem debugging flow; the subsystem debugging process is used for realizing the debugging of the specified subsystem;
and when the test content is a debugging component, executing a preset component debugging flow. The component debugging process is used for realizing debugging of the specified component.
Specifically, the subsystem is composed of a plurality of components, and the plurality of components form a cycle to form a subsystem. Including, for example, air systems, hydrogen systems, circulating water systems, and the like. The method divides the testing process of the fuel cell system into two branches, and can realize manual testing and automatic testing. When a preset automatic test flow is executed, the stack test can be performed according to a conventional method, including setting parameters of the fuel cell system and completing the automatic test of the stack.
When the management user selects manual testing, the test content in the test selection instruction is analyzed, and the functions of manual parameter setting, subsystem debugging or component debugging and the like are performed according to the test content. The management user may select subsystems and components that need to be debugged for debugging. The subsystem debugging process or the component debugging process is different for different subsystem or component settings. The administrative user may also set one or several parameters depending on the actual situation.
The method can enable a management user to select automatic testing or manual testing according to self requirements, and the management user sets parameters of the fuel cell system manually and solidifies the set parameters in a program, so that the performance of the electric pile is improved. The administrative user may also choose to perform individual subsystem commissioning or individual component commissioning to optimize the performance of the fuel cell system.
Compared with the traditional test method, the method has the advantages that the maximum power test of the 40KW, 60KW and 80KW electric pile is improved by 10 percent on average, the performance of the electric pile is greatly improved, the after-sale maintenance time is reduced by half compared with the prior art, and the troubleshooting efficiency is greatly improved.
Preferably, after executing the preset component debugging process, the method further includes:
recording historical operation data of each subsystem or component when the fuel cell system normally operates;
when the preset investigation time is up, acquiring the operation data of each subsystem or component in the current fuel cell system, and comparing the operation data with historical operation data;
and when the comparison results are inconsistent, judging that the corresponding subsystem or component in the fuel cell system has a fault, generating reminding information and sending the reminding information to a management user.
Specifically, the method is used for recording historical operation data of various subsystems or components when the fuel cell system operates normally, and the historical operation data identifies the data of the normal operation of the fuel cell system. The troubleshooting time can be set according to the requirements of management users, the troubleshooting time is set to be short, the troubleshooting frequency is high, and the troubleshooting is more timely. The checking time is set to be longer, the checking frequency is lower, and occupied system resources are saved.
When the method is used for checking, the real-time collected operation data is compared with historical operation data, if the comparison result is inconsistent, the real-time collected operation data is abnormal, and a corresponding subsystem or component in the fuel cell system is considered to be in fault, for example, if the real-time collected operation data of the air system is inconsistent with the historical operation data, the air system is considered to be in fault. The reminding information is used for reminding a management user which component or subsystem has a fault, so that the management user can know the fault condition of the fuel cell system in time and carry out maintenance or troubleshooting. The method supports fast troubleshooting of complex electric pile system faults and is convenient for after-sale maintenance.
Preferably, the method further comprises, after said determining that the corresponding subsystem or component of the fuel cell system is faulty:
generating corresponding test contents according to the failed subsystem or component;
executing a corresponding subsystem debugging flow or a component debugging flow according to the generated test content;
and generating the troubleshooting information according to the execution result and sending the troubleshooting information to the management user.
Specifically, the method can perform automatic fault detection according to the checked fault information, for example, when the method detects that the air system has a fault, test content for detecting the air system is generated, a subsystem debugging flow corresponding to the air system is called, and a corresponding debugging flow is executed. After the debugging process is executed, generating troubleshooting information according to an execution result, for example, executing a subsystem debugging process of an air system, and generating the following troubleshooting results according to the execution result: air system failure or air system health. Therefore, the method can automatically test the subsystems and the components after the faulty subsystems and the faulty components are checked, judge whether the subsystems and the faulty components really have faults or not according to the test result, inform a management user, and facilitate the management user to carry out timely after-sale and maintenance.
Preferably, after receiving the test selection instruction input by the management user, the method further includes:
and receiving and analyzing a test mode switching instruction input by a management user, and switching the test mode into an automatic test or a manual test according to an analysis result.
Specifically, the method also has the function of switching the test mode by the management user, so that the management user can switch the test mode into an automatic test or a manual test in the test process of the fuel cell system, and the use is convenient.
Example two:

as shown in fig. 2, the camera device comprises a control module 1, an angle adjusting mechanism and a camera 2, wherein the camera 2 sends the surveillance video to an external terminal through a communication module, so that related personnel can conveniently call the surveillance video at any time.
