Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, be the hardware structure figure of the embodiment of a kind of continual temperature-humidity monitoring data transmission system of the present invention.In figure, system comprises the application server 1, communication network 2, master controller 3 and the humiture transducer 4 that connect successively; Master controller 3 comprises: Power Management Unit 31, transmitter communication unit 32, server communication unit 33, data buffer storage unit 34 and single-chip microcomputer 35.
Wherein, communication network 2 can adopt internet in the present embodiment, and the server communication unit 33 of master controller 3 consists of Ethernet chip, Ethernet transformer and RJ45 joint, and is linked in communication network 2 by RJ45 joint.Transmitter communication unit 32 can be made up of RS485 chip (as SP491) and relevant control circuit in the present embodiment, is connected with multiple humiture transducers 4 by RS485 bus.Data buffer storage unit 34 for have a power failure or suspension situation under the humiture data that gather of buffer memory, data buffer storage unit 34 is mainly made up of storage chip, and storage chip has EEPROM and Flash conventionally, in the present embodiment, adopt Flash chip, EEPROM relatively, Flash chip has memory capacity greatly and the fast characteristic of access speed.And single-chip microcomputer 5 can adopt ARM9 or STM32, also can adopt STM8, in the present embodiment, select STM32, to better support jumbo storage chip, improve the scalability of system.
As shown in Figure 2, be the master controller Power Management Unit hardware composition frame chart of the embodiment of the present invention.Power Management Unit 31 comprises accumulator 312 and feed circuit 311, be used for master controller 3 and connected humiture transducer 4 centrally connected power supplies, use under normal circumstances mains-supplied at civil power (AC), after civil power power-off, adopt accumulator 312 to power, civil power power-off incoming telephone signal and accumulator electric-quantity are offered to single-chip microcomputer 35 simultaneously.
Next will further illustrating the composition of feed circuit 311, as shown in Figure 3, is the schematic block circuit diagram of master controller 3 Power Management Unit 31 of the embodiment of the present invention.Civil power, by after decompression rectifier filter circuit 3111, becomes direct current output, and is connected respectively to civil power power-off and comes power detection circuit 3112, battery charging circuit 3113 and power switching circuit 3114; Wherein, civil power power-off carrys out power detection circuit 3112 and is output as switching value, and such as " 0 " represents civil power power-off, " 1 " represents the mains supply comes out, and a road is connected with single-chip microcomputer 35, and a road is connected with battery charging circuit 3113; Battery charging circuit 3113 is for charging to accumulator 312.And power switching circuit 3114 is according to civil power, power-off carrys out the switching value that power detection circuit 3112 exports and switches, if the mains supply comes out is switched to the powered by direct current that decompression rectifier filter circuit 3111 provides, if civil power power-off is switched to accumulator 312 and powers.Centralized management for the ease of master controller 3 to power supply, feed circuit 311 also comprise battery tension sample circuit 3115, to after the magnitude of voltage sampling of accumulator 312, through A/D, conversion outputs to single-chip microcomputer 35.
As shown in Figure 4, be the functional block diagram of application server and the single-chip microcomputer of the embodiment of the present invention.Described single-chip microcomputer 35 comprises: data acquisition module 351, communicate by letter for gathering the humiture transducer 4 being connected with master controller 3, and timing acquiring humiture data; Data transmission blocks 352, for packing the humiture data that collect send to application server 1 by communication network 2; Data cache module 353, stores the storage chip of data buffer storage unit 34 into for data transmission blocks is sent to failed packet, and the humiture record that reads buffer memory offers data transmission blocks 352 to resend application server 1.Described application server 1 comprises: data reception module 11, the packet sending for receiving and resolve master controller; Data memory module 12, for being saved in database by the humiture record obtaining after resolving.
In the present embodiment, by the humiture transducer 4 in poll 485 buses one by one to gather humiture data, data acquisition module 351 is communicated by letter with the humiture transducer 4 being connected thereon by Modbus agreement, can adopt RTU pattern for improving communication efficiency simultaneously.Application server 1 is connected by communication network 2 with master controller 3, if communication network 2 adopts internet, application server 1 can pass through ICP/IP protocol or UDP/IP protocol communication with master controller 3 so.UDP/IP protocol communication is quick and be easy to realize relatively more applicable this embedded device of primary controller 3 in embedded device.But UDP/IP agreement does not have acknowledgement mechanism, cannot sentence primary data bag and whether send successfully, therefore in the present embodiment, adopt a kind of improved UDP/IP agreement, i.e. RUDP/IP agreement.This agreement is set up acknowledgement mechanism on the basis of UDP/IP agreement, and therefore, by this acknowledgement mechanism, whether data transmission blocks 352 just can be sentenced primary data bag and send successfully.
Described data transmission blocks 352 also, for after the packet sending new collection, whether packet being sent successfully and judged, if sent unsuccessfully, is notified described data cache module 353 buffer memory humiture data; If sent successfully, notify described data cache module 353 read the humiture caching record of the unsuccessful transmission that is less than assign thresholds and will after described humiture caching record packing, send to application server 1
If, by its buffer memory, so just there is the problem sending as to when for the humiture record being buffered in storage chip in Packet Generation failure.In preferred situation, often just need selective system free time to send the humiture record of these buffer memorys.Conventionally send after packet in data transmission blocks 352, if successfully sent, show that network is unobstructed, sending after packet simultaneously, often need to wait for a period of time and just enter the data acquisition of next round, therefore can, after successfully sending, detect the humiture record of buffer memory, and select the humiture record of some to send.If the humiture record of the unsuccessful transmission of buffer memory is all sent, just may exist after long power-off or suspension, cause a large amount of caching record, such as 1000, if now select all to send, so just may cause network congestion, the time delay of simultaneously reading storage chip, packing and Internet Transmission is excessive, also may cause delaying the time of new round data acquisition, therefore need to select the record of some to transmit, such as 50.Each dominant record number of selecting transmission often needs to decide according to the requirement in the time interval of humiture data acquisition.If the dominant record number of each transmission is set as 50, the each caching record that only need to read out 50 unsuccessful transmissions of data cache module 353 so, after these 50 records packs and are sent, wait for timing to data acquisition module 351 by the humiture transducer 4 in continuation poll 485 buses with collection humiture data.Should from storage chip, read the humiture record of how many unsuccessful transmissions actually at every turn, often just need to determine according to the frequency acquisition of humiture.If frequency acquisition is high, that specifies so records number and should lack, and if frequency acquisition is low, the number that records of specifying so can be relatively more.If assign thresholds is N, can set based on experience value the value of N, as 500, that also can estimate that this should read according to following formula records number N:
Wherein, " send packet time-out time " and refer to that predefined packet sends the maximum time that rear wait application server is replied, and often needs to set based on experience value.Single-chip microcomputer dormancy time is also the time of setting in advance, and especially, under storage battery power supply state, the dormancy time that extends single-chip microcomputer is conducive to reduce the consumption of electric weight.
The packet that the humiture record of described data cache module 353 buffer memory in storage chip and described data transmission blocks 352 send to application server 1 at least comprises: monitoring point, acquisition time and humiture value; The data memory module 12 of application server 1 is stored humiture record take monitoring point and acquisition time as major key, to guarantee the uniqueness of data.
Situation about sending after the data that may cause first gathering due to this data buffer storage mechanism also can cause Data duplication to send under some abnormal conditions, therefore, is necessary further to guarantee the uniqueness of data.Often can guarantee the uniqueness of data by checkpoint and acquisition time.Checkpoint adopts " master controller IP address "+" humiture transducer Modbus station address " to carry out unique identification in the present embodiment, and the system time of the master controller 3 of acquisition time when to be master controller 3 gather humiture data.
For guaranteeing that abrasion equilibrium is to improve the serviceable life of storage chip, in the time of described data cache module 353 access record, adopt circulation storage algorithm access record in storage chip, after the humiture record of unsuccessful transmission in storage chip successfully being sent by data transmission blocks 352, data cache module 353 is not deleted it immediately and is only labeled as and sends successfully at every turn; In the time sending caching record to described application server 1, described data cache module 353 only reads the successful caching record of unmarked transmission and sends data transmission blocks 352 to, and data transmission blocks 352 is by its packing and send to application server 1.
Under the not high environment of some network communication qualities, may there is the situation of frequent suspension, so just may cause frequent access data, and common all average life problems of storage chip.If read caching record and just caching record deleted after successfully sending at every turn, so just may cause humiture record to be always buffered in the Er Duigai region, a certain region of storage chip erasable frequently, also just may cause storage chip just to occur bad block at short notice and make the reliability decrease of whole system.Especially in this monitoring system, if in the higher situation of the frequency of image data, adopt the words of storage chip as the carrier of data buffer storage, just may cause erasable very frequent and storage chip is easily broken down and reduced the reliability of system, therefore adopting and optimize and be easy to the access algorithm of data buffer storage of realizing, is very important and necessary for the reliability that improves whole system.About the circulation storage algorithm of storage chip, correlation technique document has detailed discussion.And in the present embodiment, adopt the one storage algorithm that simply and efficiently circulates, if Fig. 5 is the single-chip data memory module of the present embodiment workflow diagram based on circulation storage algorithm, comprising:
S51, set up a storage pointer and indicate new memory address, storage pointer is kept at the ad-hoc location of storage chip rather than is stored in RAM, can not lose with the record of guaranteeing in power-off or store pointer after restarting.
S52, while storing data at every turn, start to store data from the position of storage pointer indication, and according to the data volume of storage, will after storage pointer, move, point to new memory address; In the time storing the afterbody of pointed address space, storage pointer is set to 0, start anew to store data.
S53, each humiture by the unsuccessful transmission in storage chip record are not deleted immediately after reading and successfully sending and are only labeled as and send successfully.
This circulation storage algorithm adopting in the present embodiment may cause the humiture record of some unsuccessful transmissions capped, if but adopt storage space enough large Flash chip just can avoid this phenomenon.Under the frequency acquisition of 1 minute, each data cached record accounts for 32 bytes, and the in the situation that of complete suspension, every day, each monitoring point took the buffer memory capacity of 45K so.If there are 10 monitoring points on master controller, will take 450K every day, and the in the situation that of suspension always, the Flash chip of 64M capacity just can the buffer memory data of 145 days.Therefore, select appropriate memory capacity according to check point quantity and frequency acquisition, just can effectively avoid the humiture of buffer memory to record capped problem.
Described single-chip microcomputer also comprises power management module 354, for regularly detecting power supply state, and under accumulator 312 power supply states, detect the magnitude of voltage of accumulator 312, in the time that being less than assign thresholds, the voltage of accumulator 312 sends alarm or/and warning message is sent to application server 1 by data transmission blocks 352.
Conventionally, the electric weight that detects accumulator all adopts the mode of surveying voltage, and in the time that accumulator 312 electric weight are sufficient not, reminding user is also necessary in time.Such as under storage battery power supply state, if accumulator 312 supply voltages are 12V, assign thresholds 10.8V so under normal circumstances, when being less than 10.8V, the power management module 354 of master controller 3 sends alarm.This alarm can be pointed out by utilizing hummer to send prompt tone on master controller 3, also alarm can be sent to application server 1 and point out.
As shown in Figure 6, be the workflow diagram of the method for the present embodiment.First, provide the application server 1, communication network 2, master controller 3 and the humiture transducer 4 that connect successively.Master controller 3 comprises: Power Management Unit 31, transmitter communication unit 32, server communication unit 33, data buffer storage unit 34 and single-chip microcomputer 35.Specific works flow process comprises the steps:
The Power Management Unit 31 of S61, master controller 3, to master controller 3 and humiture transducer 4 centrally connected power supplies that connect thereof, is used mains-supplied under normal circumstances at civil power, adopts accumulator 312 to power after civil power power-off.
S62, power on after, the connected humiture transducer 4 of master controller 3 is communicated by letter, and timing acquiring humiture data.
S63, master controller 2 are packed the humiture data that collect send to application server 1 by communication network 2.
S64, judge whether packet sends successfully, if send successfully, perform step S66, otherwise execution step S65.
S65, master controller 3 in storage chip, and go to step S62 by humiture data buffer storage.
Whether S66, the further inspection of master controller 3 have the humiture record of buffer memory, and read the successful humiture record of the not transmission of the buffer memory that is less than assign thresholds and pack and send to application server 1, and go to step S62.Wherein, if assign thresholds is N, can set based on experience value the value of N, as 500, that also can estimate that this should read according to following formula records number N:
" send packet time-out time " and refer to that predefined packet sends the maximum time that rear wait application server is replied.Single-chip microcomputer dormancy time is also the time of setting in advance, and especially, under storage battery power supply state, the dormancy time that extends single-chip microcomputer is conducive to reduce the consumption of electric weight.
S67, application server 1 receive, resolve the packet that master controller 3 sends and the humiture that parsing is obtained record is saved in database.
Wherein, in master controller 3, the humiture of buffer memory record and the packet that sends to application server 1 at least comprise: monitoring point, acquisition time and humiture value; Application server 1 is stored humiture record take monitoring point and acquisition time as major key, to guarantee the uniqueness of data.
Further, for guaranteeing that abrasion equilibrium is to improve serviceable life of storage chip, described master controller 3 adopts circulation storage algorithm, the humiture of unsuccessful transmission in storage chip record at every turn successfully send after not deletion immediately and being only labeled as send successfully; While sending caching record to application server 1, only successful unmarked transmission caching record is read and packed and send to application server 1.
Further, described master controller 3 regularly detects power supply state, and under accumulator 312 power supply states, detects accumulator 312 magnitudes of voltage, in the time that accumulator 312 voltages are less than assign thresholds, sends alarm or/and warning message is sent to application server 1.
