[embodiment]
Below in conjunction with drawings and Examples the Ni-MH battery voltage check device is further described.
The traditional nickel hydrogen battery changes into the equipment of producing employing and all the loop cell voltage is not detected.Like this, in actual production process, often occur causing cell voltage, battery carried charge abnormal situation to occur because of the various artificial equipment reasons that reach, battery taking place easily because of over-discharge causes battery no-voltage, leakage situation, has caused large-tonnage product to be scrapped, cost allowance.
Based on this, provide a kind of Ni-MH battery is changed into the Ni-MH battery voltage check device that the loop Ni-MH battery in the production detects and plays a protective role.
The Ni-MH battery voltage check device of an embodiment as shown in Figure 1 comprises: detection module, voltage processing module, CPU module and output control module.
Detection module can detect the magnitude of voltage of the different Ni-MH batteries that change into production equipment, is the interface that changes into production equipment and Ni-MH battery checkout equipment.Detection module detects Ni-MH battery by the mode of circulating sampling; Detection module is arranged on the loop check point that changes into production equipment.
The voltage processing module can change into digital signal with voltage signal, and the voltage processing module comprises AD converter.
The CPU module is the core of Ni-MH battery voltage check device, has data processing function and order deixis.
Output control module receives the order indication of CPU module, and makes corresponding physical operations, to changing into production equipment protection.
The concrete course of work of this Ni-MH battery voltage check device is as follows:
Whether the detection of CPU module changes into production equipment and moves, if instruction is not sent in not operation, if change into the production equipment operation, the CPU module is sent to detect to detection module and instructed.
Detection module receives the voltage signal that detects instruction and detect Ni-MH battery, and voltage signal is input to the voltage processing module.
The voltage processing module receives voltage signal and converts voltage signal to digital signal, and digital signal is input to the CPU module.
CPU module receiving digital signals, and judge according to digital signal whether Ni-MH battery is in normal condition, if normal, do not send instruction, unusual if Ni-MH battery occurs, the CPU module is sent the protection instruction.
Output control module receives the protection instruction, and makes the physical operations of cutting off the electric current that unusual Ni-MH battery occurs according to the protection instruction, makes actuation of an alarm simultaneously.
Actuation of an alarm can be the variation of pilot lamp, and alarm bell is rung etc.
This Ni-MH battery voltage check device has also comprised the power module of power supply function, and power module can directly link to each other with the CPU module, also can take other connected mode.
Because the difference of input and output voltage between each module, this Ni-MH battery voltage check device also comprises optocoupler, optocoupler is arranged between each module and (between detection module and the voltage processing module optocoupler is not set), utilizes optocoupler to carry out the isolation between the input and output and the level conversion of input and output voltage.
Because input impedance low reaching in loop exists signal to disturb between formation device loop and the Ni-MH battery voltage check device, between detection module and voltage processing module, be provided with voltage follower in the present embodiment, effect is to strengthen input impedance, eliminate the circuit interference and keep input sample voltage stable, and voltage follower adopts OP07 as amplifier.
