The energy and environmental problem have become one in the world by the topic of extensive concern at present.Tradition primary energy is increasingly sharpening of scarcity and atmospheric pollution level gradually, all force various countries accelerating paces aspect research and development new forms of energy, especially the impact of the carbon dioxide that ever-increasing vehicle and work heat engine give off on Atmospheric composition composition, has caused warming of global climate.Hydrogen energy fuel battery is a kind of device that directly chemical energy dress is changed into electric energy, and therefore the advantage such as have low noise, pollution-free, power variable, system is reliable, suitable environment ability is strong becomes the emphasis direction of whole world research.So long as it can be used in the place of electricity consumption, as factory, power station, electric automobile, Aero-Space, the fields such as steamer, but his transfer process is subject to extraneous factor impact, the power particularly sending is higher, just higher to outside conditional request, just need control system to control these external factor, as: the temperature of pile, humidity, voltage etc., what fuel cell adopted simultaneously is that hydrogen is as fuel, just need to control the flow of air inlet, control automatic unlatching and the shutoff of some valves simultaneously, make the voltage that fuel cell produces can safety, be applied in load easily.Traditional electric motor car, each user uses the electricity of storage battery the inside, just need to change storage battery and charge, more loaded down with trivial details.The present invention adopts dual power supply system, does not need external power source charging, to user, has brought very large convenience.
Summary of the invention
The object of type of the present invention is:
1. when fuel cell is used in electric power system, user can observe by display screen the operating state of fuel cell, engineer can carry out the operating state of fuel metering battery by button simultaneously, for the performance difference of each fuel cell, finds out best operating state.
2. realize Dual-power automatic switching function, realize automatic charging.
3. by automatically controlling the break-make of supply load voltage, realize load current anti-reverse, prevent that reverse current is to causing the infringement to pile.
4. by toggle switch, can select three kinds of different running parameters, meet the demand of different user.
5. by single-chip microcomputer, control the automatic watering that water valve is realized humidifier, when the water level of water tank the inside is too low, water valve is opened and is added water, surpasses set point water valve and automatically closes.
The technical solution of type of the present invention is: the hydrogen energy fuel battery control system below a kind of 10kW of being applied to, it is characterized in that passing through when system has just started to start storage battery power supply, the voltage by DC-DC voltage reduction module, fuel cell having been produced after having started drops to 13.8V to system power supply, charges a battery simultaneously.By toggle switch, select the operating state of fuel cell, be divided into A, B, tri-kinds of patterns of C, after model selection, can enter parameter by button and regulate pattern, carry out the parameter of fuel metering battery: the relation of rotation speed of the fan and temperature, electric current, the relation of exhaust frequency and electric current, the cut-in voltage of load and shutoff voltage, activation number of times in the maximum of electric current, start activation number of times and fuel cell operation process and time etc., to make operation of fuel cells in optimum state.When fuel cell is in the process of operation; occur when abnormal; buzzer warning and the flicker of screen relevant parameter, also can point out " please process abnormal " extremely to solve and can point out " please start shooting " afterwards meanwhile on screen; after starting shooting successfully, can show " in service "; facilitate user to find the reason of reporting to the police, and solve in time, so both protected pile also to prevent that load is impaired; make the load can safety, operation stably.
The beneficial effect of type of the present invention is: by showing and automatically controlling, better protects pile, improves life-span and efficiency, facilitate user to understand the operating state of fuel cell simultaneously, can be safer, and trip stably.
Accompanying drawing explanation
Fig. 1 is a kind of hydrogen energy fuel battery control system schematic diagram being applied to below 10kW.
Fig. 2 is a kind of hydrogen energy fuel battery control system workflow diagram being applied to below 10kW.
Embodiment
Accompanying drawing has been shown structure and the work embodiment of type of the present invention.In systematic schematic diagram:
1, sensor assembly 2, reverse current detection module 3, dual power supply and automatic charging module 4, mode selection module 5, electromagnetically operated valve module 6, display module 7, blower module
Below comprehensive accompanying drawing type of the present invention is further illustrated.
First whole system is powered by the 12V storage battery in dual power supply and automatic charging module (3), can pass through the button in display module (6), enter parameter set unit, the running parameter setting of fuel cell is entered, for example: the hyperbar value of the relation between relation table, vent valve frequency and the electric current of the temperature extremes value of the parameter of short circuit, fuel cell, maximum current, rotation speed of the fan and the temperature of load and electric current, the barometric minimum value of gas cylinder, intake valve, the unlatching of load and close voltage etc.Parameter setting completes the laggard mode selection module (4) that enters, and toggle switch is placed in respectively to A, B, C shelves, and different parameter downloads is entered, in service in program, selects which shelves, moves which section program.Single-chip microcomputer is accepted the data that temperature sensor, current sensor, baroceptor, level sensor in sensor assembly (1) collect, after analog-to-digital conversion, communicate with display module (6), be presented at liquid crystal screen display, when the data that detect and set point misfit, on display screen in display module (6), can prompting " please process abnormal ", occur that abnormal parameter can glimmer, send alarm sound simultaneously, after abnormality processing is complete, on screen, show " please start shooting ", same alarm, flicker disappears.Press starting switch, can prompting " in service " on screen.When the voltage of fuel cell generation is greater than set point, load is opened, and the DC-DC voltage reduction module in dual power supply and automatic charging module (3) drops to 13.8V to system power supply voltage simultaneously, charges a battery simultaneously.Normally in service, the high pressure valve in electromagnetically operated valve module (5) is opened, INO, vent valve according to electric current adjust the exhaust of exhaust frequency, water valve cuts out.Exhaust solenoid valve in electromagnetically operated valve module (5) changes along with the value of the current sensor detection in sensor assembly (1), and the larger exhaust frequency of electric current is faster, and electric current more float gas frequency is slower.The current related temperature also detecting with temperature sensor that fan in blower module (7) not only detects with current sensor in transducer device module (1) is relevant, while there is no electric current, fan changes along with temperature, while having electric current, along with the size of electric current, changes.Transducer detected value and set point in sensor assembly (1) misfit, and single-chip microcomputer can carry out the protection action of some row, sends alarm sound simultaneously, is convenient to user and investigates fault.Inverse detection device detects in the reverse current detection module (2) while being less than 10A, now can close load, prevents that electric current from entering pile, affects Performance data.
Function in this inventing type, has not only facilitated engineer to obtain the optimum working parameter of fuel cell, and has facilitated the use of user in daily, does not need external power source to charge a battery.The starting-up response of simultaneity factor is fast, more steady, has had assurance in safety.
