Description
Technical field
The utility model relates to a kind of detection system, more particularly, is a kind of cruising inspection system of extendible detection fuel cell monolithic voltage.
Background technology
Monolithic voltage (CVM) system that patrols and examines is the important component part in the fuel battery test system, and its security, reliability, validity are that the fuel cell test personnel effectively monitor system and the important assurance of system evaluation.
At present, known fuel cell monolithic voltage cruising inspection system all is at specific galvanic pile module, designs the correspondent voltage cruising inspection system according to the monomer voltage number of required detection, adopts single monitoring device or is monitored jointly by many covering devices.
Proposed a kind of monolithic voltage cruising inspection system towards fuel cell among the ZL200710099293.3, its system adopts single monitoring device to whole 540 fuel cells.Another kind of commonplace monitoring mode is to be detected jointly by many covers monitoring device.
Single monitoring device has certain limitation, and when the monomer voltage number of required detection need increase or reduce, its sense channel was then not enough or superfluous, the extendability deficiency; Many cover monitoring devices systems, its dirigibility is better, can select the suitable monitoring means of quantity for use according to actual testing requirement, but the coupling between each monitoring means, and the versatility when same monitoring device is used in different test macro still is apparent not enough.
The utility model content
For solving the problems referred to above that above-mentioned prior art exists, the utility model proposes a kind of extendible fuel cell monolithic voltage cruising inspection system, native system need not change hardware configuration and slave computer software just can realize many covering devices co-operation, is easy to expansion, has good versatility.
The utility model can be solved by the following technical programs:
A kind of extendible fuel cell monolithic voltage cruising inspection system, per two fuel cell voltage signals in the fuel cell pile by outputing to corresponding operational amplifier after the divider resistance dividing potential drop, output to the A/D port of single-chip microcomputer respectively again through this operational amplifier.
As preferred embodiment of the present utility model:
Single-chip microcomputer described in the utility model is connected with reference voltage; The I/O port of described single-chip microcomputer is connected with one or four DIP switches; Described single-chip microcomputer adopts MC9S08DZ60.
Because adopt above technical scheme, the utility model can reach 0.01V to the accuracy of detection height of fuel cell voltage; Can be according to actual needs, the DIP sign indicating number of fuel cell cruising inspection system is set to different values, makes the collaborative work of a plurality of monitoring means energy to be beneficial to expansion.

Embodiment
Below in conjunction with embodiment, further set forth the utility model:
As shown in Figure 1, a kind of extendible fuel cell monolithic voltage cruising inspection system, per two fuel cell voltage signals in the fuel cell pile by outputing to corresponding operational amplifier after the divider resistance dividing potential drop, output to the A/D port of single-chip microcomputer respectively again through this operational amplifier.The single-chip microcomputer outside is connected to the reference voltage of 4.096V, has guaranteed the high precision of A/D conversion.Single-chip microcomputer adopts MC9S08DZ60, its cost is lower, supports the CAN network, because the ADC module of MC9S08DZ60 has 24 tunnel analog input interfaces, so a single-chip microcomputer can be measured 24 road voltage signals, is very suitable for the exploitation of fuel cell voltage polling system.
The I/O port of single-chip microcomputer is connected with one or four DIP switches, and the ID that scm software transmits and receive data according to the address modification of DIP switch automatically, the facility of bringing thus mainly is: a plurality of modules can adopt same program, need only according to order during use and set the address.As shown in Figure 2, DIP switch one end ground connection in parallel, the other end is connected to four I/O ends of single-chip microcomputer, and at first I/O is set to read, and the pull-up resistor with the corresponding port in dial-up position enables again, and reads outside switching value.With the external parameter that reads increment as the initial ID of Frame.By the break-make of four DIP switches being controlled this CVM unit of mark uniquely, four DIP switches always have 16 kinds of DIP sign indicating numbers, so can realize that at most 16 CVM work together, press per two fuel cells as a voltage detection signal, this system can extend to and detect 24*2*16=768 sheet fuel cell, can satisfy the pile test request of the present overwhelming majority.The figure place of DIP switch can also continue to increase, and its expansion scale is also in ratio increasing.
Concrete test cases 1: in standby power supply fuel cell system test platform, need the pile monomer of test to add up to 90, adopt two monomer voltages as a test signal, actual need the test voltage number of signals be 45, adopt 2 CVM unit, its DIP sign indicating number is set to 0001 respectively, 0010, host computer, the FCU unit is to CAN communication network timed sending trigger frame, the monomer voltage information of gathering to CAN communication network feedback successively after the trigger pip is received in 3 CVM unit, host computer, the FCU unit receives corresponding Frame by extracting different ID number, and real-time display voltage signal.
Concrete test cases 2: use in the pile test platform at the 10kW car, need the pile monomer of test to add up to 144, adopt two monomer voltages as a test signal, it is 72 that reality needs the test voltage signal altogether, adopt 3 CVM unit, its DIP sign indicating number is set to 0001,0010 respectively, 0011, host computer just can obtain real-time voltage feedback signal by the transmission trigger frame in cycle.
In two case study on implementation, the CVM unit that adopts is identical, only need to select quantity appropriate C VM unit according to the pile number of monomers of being tested, and its DIP sign indicating number is set to different values, host computer and FCU unit just can obtain the correspondent voltage signal, and the pile operation conditions is monitored in real time.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
