Description
[technical field]
The invention belongs to uninterrupted power source (Uninterruptible Power Supply, following abbreviation UPS) technical field, especially relate to a kind of method and apparatus of the UPS of test control module.
[background technology]
The UPS control module is the core ingredient of control UPS entire work process, it mainly is made up of main control chip and some peripheral circuits. and main control chip and software thereof are the cores of UPS control module, mainly finish UPS power part voltage, the collection of data volume such as electric current and temperature, and the simulated data of gathering carried out computing and processing, and the digital signal of gathering carried out logic determines and processing, and send control signal and give power section, action in order to each device of power controlling part, finish the conversion of operation state of UPS, receive and send the human-machine interactive information input simultaneously, the signal output of processing and demonstration etc.
In order to ensure UPS machine system function and performance, often need carry out special test for the UPS control module. test is mainly carried out at its main control chip in house software, comprise the collection of software to UPS complete machine data, computing, whether correctly handle, whether the control to the UPS course of work is correct. but for the programming of UPS control module hardware and Control Software, debugging and test, the conventional at present method of each UPS producer is Control Software all to be write finish, then control module is installed on the UPS complete machine and debugs and test, done following shortcoming like this:
(1) in the UPS initial stage of development stage; the UPS hardware components is not usually also finished design; the UPS Control Software does not just have suitable debug platform like this. therefore; the software developer must wait for after the UPS hardware design is finished just can carry out software debugging, thereby has incured loss through delay the exploitation and the debugging progress of UPS Control Software and total system.
When (2) debugging in the UPS Control Software initial stage of development stage, owing to be just to have finished writing of software, be difficult to guarantee the correctness of Control Software. and that the UPS control module plays a part in complete machine is very crucial, in case the inaccurate or logic error of software sequential takes place, the danger that is easy to cause UPS complete machine components from being damaged even blast is arranged.
(3) because the UPS complete machine usually is to be operated in normal condition, just become difficult to achieve for the test of some abnormal protection states. for example,, utilize actual UPS machine system to test for the detection and the defencive function of faults such as internal components overvoltage.
(4) it is very big to carry out the randomness of software test of control module on the UPS complete machine, may be for different testers, and its method of testing, content measurement be difference to some extent all. and therefore, the comparability of test result is just very poor.
(5) the UPS Control Software is after development﹠ testing finishes, enter maintenance phase, after software is made an amendment, need carry out regression test. and very big in the workload of the enterprising line retrace test of complete machine, the all functions of UPS all must be tested one time, could guarantee the correctness behind this software modification. therefore, this method will spend a large amount of regression test time, and testing efficiency is very low.
(6) test at present all is that the developer finishes disposable the writing of UPS Control Software, and then debug and test. a lot of problems will be left over test phase like this. even some fault that is easy to search at initial stage of development, owing in time do not find, become very hidden to test phase, even can't find, stayed very big hidden danger to software.
(7) in the past when producing for the debugging of control module, produce it to be installed on the complete machine after good to debug if be. owing to the reason of producing causes control module wrong, but producing the commissioning staff does not find, debug in case be installed on the UPS complete machine, just might cause consequences such as complete machine damage, and utilize machine debugging, time-consuming effort again.
