Description
Technical Field
The invention relates to the technical field of fire-fighting equipment manufacturing, in particular to a method for solving false alarm of an automatic fire extinguishing system in a kitchen.
Background
The kitchen automatic fire extinguishing equipment control panel belongs to AC/DC power supply and can work, but the control panel of the existing kitchen automatic fire extinguishing system often has false alarm faults when the storage battery supplies power. The main reason is that in the uncontrolled SHUTDOWN voltage of the chip 8002A, SHUTDOWN is usually called SHUTDOWN, the high level is low level, the low level is high level, and the false alarm fault occurs as a result. It can be said that 8002A is an electronic switch with SHUTDOWN mode, which has a SHUTDOWN pin to turn off the bias circuit of the operational amplifier, and when the level is high, the voltage level is applied to the SHUTDOWN pin to turn off the operational amplifier, so that the output is disconnected from the speaker.
The control panel is controlled by a pin of the microprocessor, and the microprocessor can provide a quick and smooth level conversion to control the high-low change of the voltage level of the SHUTDOWN off end of 8002A, wherein the low is an access and the high is a closing.
In principle, the turn-off function of 8002A is controlled by the pin of the microprocessor, and the existing microprocessor only sets the voltage of the shut down pin of 8002A to be low level when under-voltage state, and the electronic switch is in the on-state, and controls the relay pull-in and walk-in alarm program of the alarm device (that is, adopting unidirectional processing technology, under-voltage alarm only designs the control program for under-voltage state, and one-element function control is adopted in one-to-one correspondence). However, when the storage battery outputs normal voltage, how to control the turn-off terminal of 8002A to be always stable in a high level state means that SHUTDOWN is performed to turn off SHUTDOWN the electronic switch, and the electronic switch is not set in the microprocessor, so that the microprocessor cannot realize level control capability.

In order to achieve the purpose, the invention adopts the following technical scheme:
a method for solving false alarm of kitchen automatic fire extinguishing system comprises a first function for returning the output voltage of a storage battery and a second function for returning the off-state voltage of 8002A, wherein the first function and the second function are defined and assigned to be stored in a register of a microprocessor of a control panel, so that the first function and the second function are returned before a relay of an alarm device performs an actuation action, and the change of the voltage of the off-state terminal of 8002A is controlled.
Compared with the prior art, the invention has the technical effects that:

Detailed Description
The present invention will be described in detail below with reference to specific embodiments. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
One embodiment of the present invention is provided below:
a method for solving false alarm of kitchen automatic fire extinguishing system comprises a first function for returning the output voltage of a storage battery and a second function for returning the off-state voltage of 8002A, wherein the first function and the second function are defined and assigned to be stored in a register of a microprocessor of a control panel, so that the first function and the second function are returned before a relay of an alarm device performs an actuation action, and the change of the voltage of the off-state terminal of 8002A is controlled.
The microprocessor of the original control panel controls the SHUTDOWN of 8002A to be at a low level only when the output voltage of the storage battery is undervoltage, so that the SHUTDOWN of the SHUTDOWN pin is switched to be on, and the relay is controlled to pull in and go into an alarm program.
The invention supplements two callback functions in a microprocessor of a control panel, wherein one function is a first function for callback of the normal (relative to an undervoltage state) output voltage of a storage BATTERY, namely macEvent L oop,// BATTERY, the other function is a second function for callback of the cut-off voltage of 8002A, namely nwk _ event _ loop,// Vhh, and the two functions are defined and assigned to be stored in a register of the microprocessor.
In this embodiment, the microprocessor of the control panel employs: STM32F103VBT6X 7B 55993, when the microprocessor receives any one of the Data defined and stored IN the register, enters the Data _ Setupo O function, executes the callback function copyRoutene O according to the request of different descriptors, fills the descriptor of the microprocessor IN the DataStageIn O function, and waits for the transmission of the IN token packet. Thus, the operation program can be entered only after the token packet → the data packet → the handshake packet. For example, GPIO _ Mode is also an enumeration type, and its value affects only the lower four bits of the register, and the function of the upper four bits can determine whether this parameter is used for the configuration of GPIO pin output Mode. The firmware library of the STM32 first defines configuration words of all registers of each device in advance, then encapsulates the configuration words in a structure or an enumeration variable, and when a firmware function corresponding to the firmware library is called, corresponding configuration words are taken out from the encapsulated structure or the enumeration variable according to an incoming parameter, and finally the configuration words are written into the registers to complete configuration of the underlying registers.
Two callback functions are newly arranged, and the two functions need to be recalled before the pull-in action of the relay is executed: a first function and a second function. These two functions receive the following parameters:
byte array, a pointer to a group of elements;
int size is the number of elements in the array;
int elem _ size, the size of an element in the array, in bytes;
CompareFunction cmpFunc with the prototype pointer to the callback function.
The first function and the second function both sort the array, but each time it is decided which of the two elements is in front of it, one of the functions is a callback function whose address is passed in as a parameter. What is needed is to care about the addresses of the two elements used for comparison and to return a certain value.
Any value is sent to the buffer area of the microprocessor for storage after being in error, and the microprocessor returns a negative identifier 1 (the positive data byte is temporarily set to be 0, and the negative data byte is set to be 1) after receiving the alarm request. Thus, when the value is strictly defined into the function, the descriptor must be satisfied at the same time to obtain confirmation. So that the state control is not so thin. Only when the microprocessor receives any one of the two Data, the microprocessor enters a Data _ setup O function, the function executes a different callback function copyroute O according to a different descriptor requested, fills the descriptor of the descriptor sending microprocessor into a buffer IN a datastage IN O function, and waits for sending an IN token packet. Thus, the alarm program can be entered after the token packet → the data packet → the confirmation packet.
When the output voltage of the storage battery is normal, the pin at the turn-off end of 8002A is in a high level message SHUTDOWN, if any one of the two is wrong, the descriptor input into the microprocessor will be contradictory to the descriptor stored in the register in advance, and as a result, the microprocessor cannot obtain the confirmation of the microprocessor, and certainly, the microprocessor will send a negative reply: the character 0, the relay will not be attracted, and the false alarm phenomenon can be avoided.
The invention is described below by analyzing the program code:
step 1: the system comprises a header file defined by 51 singlechip registers;
step 2: the position defines that the relay is I/0 □ P1.3;
and step 3: a delay function;
and 4, step 4: calling back a first function;
and 5: calling back a second function;
step 6: defining an unsigned variable I, j;
and 7: the purpose of time delay is achieved through the self-nesting loop execution of I, j;
and 8: a main function;
and step 9: entering a While loop of a main program;
step 10: SampleAPP _ messagemsgcb (msgpkt); v/arrival of a packet reception event;
step 11: the format of the received data packet is: aflncoming msgpacket _ t;
step 12, unit16Date L ength// size of received data packet;
step 13: byte Date; v/the specific content of the received data packet;
step 14: os _ start _ system// packet handling function;
step 15: SampleApp _ MessageMSGCB (MSGpkt)// receiving and processing of data packets;
step 16, analyzing the content of the data packet, and when the length of the received data is uncertain, analyzing pkt- > cmd.data L ength;
if the data length is not matched, judging that a negative character 0 is wrongly sent out;
when the length of the received data packet is determined, a handshake packet confirmation (the identifier writing is 1) is sent out if the data packet can be entered;
and step 17: the relay acts (closes or opens).
Please note that:
1. calculating the delay time includes calculating the time of the clock cycle that the lcall statement of the calling function translates.
2. Actually using an unsigned type data structure;
3. actually using char type, int is not enough to be reused, and then long.
4. No floating point type is used.
Compared with the prior art, the invention has the technical effects that:
the invention adopts a binary function, namely two callback functions are supplemented to a microprocessor at the same time to control the attraction of a relay, compared with the existing unary callback function control, the binary callback function control has more reliable data transmission, more optimized function exertion, more sensitive and reliable data source and destination, thereby solving the problem of false alarm fault.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
