After detecting sub-process and beginning, at first open the timer of 1000 times/per second, timer produces a look-at-me and detects once, detects lateral seismic wave sensor and the data of seismic wave sensor longitudinally at every turn.
Have no progeny in the timer, detect lateral seismic wave sensor signal, lateral seismic wave sensor signal is stored in the interior storage of controlling oneself; Detect again longitudinally seismic wave sensor signal, seismic wave sensor signal longitudinally is stored in the interior storage of controlling oneself.
Detect number of times and add 1, less than 30 seconds, continue to detect, by 30 seconds, set and send routine denotation, then setting data compression sign closes timer, the calling data condensing routine.
The timer number of times is 60000 times, takies two bytes, a high byte, a low byte, maximum 65535 times of two bytes.
The compression process of step 204 as shown in Figure 2 pair data mainly adopts the Huffman coding, about process flow diagram such as Fig. 4, shown in Figure 5 of Huffman coding.
The Huffman coding is the coding method that can reach the minimum average B configuration code length to adding up independent source that is proposed by Huffman nineteen fifty-two.This year, he has delivered famous paper " A Method for the Construction of Minimum Redundancy Codes ", the i.e. building method of short redundanat code. afterwards, it is one of study hotspot of field of data compression that Huffman coding and some are improved one's methods always.The Huffman code is a kind of variable length code, and its basic thought is: the probability that each gray scale occurs in the first statistical picture (digitizing), and the larger tax of probability of occurrence is with shorter code word, and what probability of occurrence was less then composes with long code word.We can represent the process of Huffman coding like this: in whole cataloged procedure, this two step of the probability that each gray level of statistical picture occurs and coding is all very simple, and crucial is the structure of Huffman tree.Not only coding the time need to be used this tree, also must have this tree just can finish decoding work in the time of decoding, and therefore, the Huffman tree must be complete is transferred to decoding end.The structure of Huffman tree can be finished according to the process flow diagram of Fig. 4 or Fig. 5.At first the probability that comes out is sorted from small to large, then with two probability additions of minimum; When arriving here, delete from the probability formation first two nodes of two probability that added as tree, and them; Then the new probability of addition gained is joined in the formation, this new formation is sorted.
Stop when so repeatedly, to the last two probability add up to 1.Like this, the Huffman tree has just been set up.
The process flow diagram of the wireless transmission process of step 205 as shown in Figure 2 pair data as shown in Figure 6.
One earthquake Data Detection amount has the 30*2*1000=60000 byte.Approximately the 60K data volume forms the 20K-10K data volume after compression.These data send through wireless sending module.
Packed data is the packet of N segment length, during transmission, one piece of data is called in the transmission data buffer storage at every turn, is sent by data buffer storage, until the Packet Generation of N segment length is complete.
After entering the transmission sub-process, at first start timer, then call in the packet of the 1st segment length to sending buffer memory; Set the buffer memory byte number such as 20 bytes, setting transmission data total length such as N=100, set subsequently the byte figure place, a byte is by 8 bit lengths, read to send the first byte of buffer memory to transmitter register, such as A-register, one of A-register band carry lt, detecting carry digit is 1 or 0, is 1 to put that to send mouthful be 1, is 0 to put that to send mouthful be 0, whether then detect a byte is sent completely, do not send such as a byte, time-delay continued one of A-register band carry lt after the time of baud rate.If a byte sends, whether detect bag data sends, bag data do not send, the packet byte pointer adds 1, calls in next byte and continues to send, if bag data send, whether the pointer that detects data total length N finishes, if surveying data total length N is not 0, the next bag of packing into begins the transmission of a new bag to sending buffer memory.Until send data total length=0.
The highest transmission data speed of wireless sending module is the 20K/ per second.The data that send the 20K byte need 10 seconds.
In order to guarantee data integrity, can repeatedly send, this verifies the integrality that sends data with regard to requiring.
Such as a Class A building, according to " seismic design provision in building code " GB 50011-2001, geological process should be higher than the requirement of this area seismic fortification intensity, and its value should be determined by the seismic safety evaluation result of approval; Earthquake resistant construction when seismic fortification intensity is 6～8 when spending, should meets this area seismic fortification intensity and improve once requirement, when being 9 when spending, should meet than the higher requirement of providing fortification against earthquakes of 9 degree.For this reason when the building of design Class A, in building body, be furnished with differing heights, the real-time detection hardware of the antidetonation of the Building Design of diverse location, during earthquake, processor will detect the lateral seismic wave sensor of corresponding point and seismic wave sensor signal longitudinally, the Class A building has regular coding, defined the position, buildings is the Class A, the input focus is to the distance that detects building body, control center is with the above-mentioned information and the earthquake information that obtain the Class A building, with according to model analysis, obtain this Building Design and whether reach, when being 9 when spending, should meet than the higher requirement of providing fortification against earthquakes of 9 degree.
