Specific embodiment
Below with reference to specific embodiment, the present invention will be described in detail.But these embodiments are not intended to limit this hair
Bright, structure that those of ordinary skill in the art are made according to these embodiments, method or conversion functionally include
Within the scope of the present invention.
One embodiment of the present invention presented below：
A kind of method for solving kitchen automatic fire extinguishing system false alarm, including be used to adjust back accumulator output voltage the
One function and the second function for the shut-off voltage of 8002A to be adjusted back, the first function and second function are defined and assigned
Value is stored in the register of the microprocessor of control panel, with described in the readjustment before the relay of warning device performs adhesive action
First function and second function control the height variation of the shut-off terminal voltage of 8002A.
The microprocessor of original disk control only controls the SHUTDOWN of 8002A to be in low electricity when accumulator output voltage is under-voltage
It is flat, SHUTDOWN pins is caused to switch to turn on by disconnecting, control relay actuation enters into alert program.
The present invention supplements two call back functions in the microprocessor of control panel：One is for by the normal (phase of accumulator
For under-voltage condition) output voltage readjustment first function：macEventLoop,//BATTERY；The other is for inciting somebody to action
The second function of the shut-off voltage readjustment of 8002A:nwk_event_loop,//Vhh；And two function definition and assignment are stored
In the register of microprocessor.Other codes are transferred to by function parameter in computer program design, this design
Allow for the subprogram that bottom code is invoked at high-rise definition.Take the two call back functions control the actuation of relay (
Disjunction available for control relay), the occurrence of false alarm is reliably controlled with this.
In present embodiment, the microprocessor of control panel uses：STM32F103VBT6X 7B,559 93, in the microprocessor
When device receives any one data of defined and storage in a register, Data_Setupo O functions, the letter will be entered
It is several to perform different call back function CopyRoutine O according to different descriptors is asked, and in DataStageIn O functions
The middle descriptor descriptor hair microprocessor inserts buffering area, waits IN token packets to be sent.So pass through token packet → data
Operation sequence can be just entered into after bag → handshake packet.Such as GPIO_Mode is also enumeration type, value influences the only low of register
Four, the effect of Gao Siwei may determine that whether this parameter is used for the configuration of GPIO pin output mode.The firmware library of STM32 is first
First the configuration words of all registers of each equipment are pre-defined, are then encapsulated in structure or enumerated variable, are being adjusted
During firmware function corresponding with firmware library, it can be taken out according to incoming parameter from these packaged structures or enumerated variable pair
The configuration words answered, are ultimately written in register, complete the configuration to bottom register.
Two call back functions are now newly set, relay needs to adjust back above-mentioned two function before adhesive action execution：First
Function and second function.The two functions receive following parameter：
byte*array:It is directed toward the pointer of element group；
int size:The number of element in array；
Int elem_size:The size of an element in array, in units of byte；
CompareFunction cmpFunc:The pointer of direction call back function with above-mentioned prototype.
First function and second function can all be ranked up array, but need to determine every time two elements which come before
Face, there are one being call back function in function, address transfers as a parameter.It is required take notice of be two and be used for
The address of the element compared, and return to some value.
The storage of microprocessor buffering area is issued after the error of any one numerical value, microprocessor will return after receiving alarm request
Returning a negative mark symbol 1, (temporarily setting data byte certainly, as 0,1) negative data byte is.Thus considered critical numerical value enters letter
It could be confirmed when must simultaneously meet descriptor during number.The control of such words state would not be so thin.Only micro-
Processor, which receives any one in two data, can just enter Data_Setupo O functions, which retouches according to request is different
Symbol is stated, different call back function CopyRoutine O is performed, and descriptor is sent out microprocessor in DataStageIn O functions
The descriptor of device inserts buffering area, waits IN token packets to be sent.The ability so after " token packet → data packet → confirmation bag "
Enter into alert program.
When accumulator output voltage is normal, the shut-off end pin of 8002A is in high level and SHUTDOWN is reported to turn off, and the two is appointed
If one error of meaning, the descriptor of input microprocessor will be contradicted with the descriptor of deposit register in advance, the result is that
It cannot get the confirmation of microprocessor, certain microprocessor will send the reply of negative：" character 0 " relays are surely not inhaled
It closes, wrong report phenomenon can be to avoid.
