22 2.3 TBS12B cnnectivity 3 Functinal Descriptin 3.1 Interface functin SDI-12 The SDI-12 standard defines a set f cmmands t cnfigure sensrs and t initiate measurements. Upn receiving specific cmmands, the sensr may carry ut internal tasks, respnd with infrmatin n cnversin time r send measurement data. SDI-12 cmmands are typically ASCII strings generated by the data recrder/cntrller firmware. The TBS12 is cnnected t the TX utput f the data recrder cntrller UART and cnverts the cmmand strings t the lgic levels and baud rate specified by the SDI-12 standard. Furthermre, the TBS12 mdule handles breaks, marks and all ther details f the SDI-12 prtcl. Upn receiving data r status infrmatin riginated by a Sensr, the TBS12 extracts the crrespnding ASCII strings and presents it t the RX input f the data recrder cntrller UART LRa mdem and radi TBS12 embeds a LRaWAN cmpatible mdem and a dual band LRa radi. 22

23 Depending n the frequency plan that is used (cuntry specific), either lw r high ISM band will be needed. It is therefre crucial t cnnect the antenna t the right cnnectr: As LRaWAN uses free ISM bands, useable frequencies are subject t lcal regulatin, and TBS12 must be cnfigured accrdingly: - T use supprted LRaWAN frequency plans fr cuntries where this has been defined - T use custm plans fr ther cuntries Refer t latest LRaWAN specificatin n TBS12 must be then used alng with a LRaWAN gateway that perates n the same frequency band: fr example, if TBS12 is deplyed in Eurpe, bth TBS12 and gateway must be cnfigured t use EU868 frequency plan. 3.2 Pwer Supplies TBS12 pwer supply depends n the variant: Sil misture & temperature cells (TBS12): 3.6V nn rechargeable battery (e.g. PulsesPlus series frm Tadiran) SDI-12 sensrs (TBS12B): 3*1.5V DCELL SDI-12 sensrs + slar panel (TBS12S) 3.7V Li-In rechargeable Capacity: mah Size must fit the battery hlder 0.72 Dia * 2.56 H (18.2mm * 65.0mm) Depending n the munting cnfiguratin, cable binders can be used t tie the battery t the PCB. 3.3 System TBS12 acts like a mini-rtu (Remte Telemetry Unit): it is designed t trigger SDI-12 measurements n a regular basis, and transmit the measurements ver LRa t applicatin server n defined time interval. SDI-12 measurements are stred in TBS12 internal memry until they re transmitted. All f these parameters are cnfigurable. 23

24 3.3.1 Time intervals Three different time intervals are defined in the system: - Measurement interval Perid in minutes t perfrm SDI-12 measurements and stre data int internal memry. - Transmissin interval - Mnitring interval Perid in minutes t transmit measurements stred in TBS12 internal memry ver LRa Perid in minutes t transmit mnitring infrmatin (eg battery level) ver LRa t the applicatin server. This must be a multiple f the Transmissin Interval. These parameters are cnfigured with the TBS12 Cnfiguratin Tl. Intervals are set in minutes frm 1min t 1440 minutes (ie 24 hurs). A transmissin delay can be set in case multiple TBS12 are deplyed in the same area. Having several TBS12 sending data at the same time will result in numerus packets cllisins, therefre staggering the transmissin f each units ver the transmissin interval will help reducing this effect. The staggering delay shuld be carefully chsen s there s n verlap with the next transmissin interval. Fllwing sequence shws 6 TBS12 units transmitting their data n a 30s slt basis spread ver a 6 minutes transmissin interval: Belw diagram shws hw TBS12 perates with a 1 hur measurement interval and 3 hurs transmissin interval: 24

25 Nte: it is strngly recmmended t use same interval fr bth measurements and transmissin (e.g. each 15 minutes) t ensure smth peratin f the RTU Cmmunicatin utage The TBS12 is able t handle 2 different situatins related t cmmunicatin utage: (1) Sme stred measurements have nt been transmitted because f empty battery (2) Data is nt received by the server because f radi transmissin issue, gateway is dwn, LRaWAN server utage, etc Situatin (1) is autmatically handled by TBS12: when the device is repwered (ie battery has been replaced ), upn the first transmissin interval it will transmit the measurements that have nt been previusly sent. Situatin (2) is handled by TBS12 nly if the device has been cnfigured t use cnfirmed messages as per LRaWAN standard: in this case, whenever a packet f data is sent by TBS12, the LRaWAN server must sent back an acknwledge t cnfirm the packet has been successfully received. 25

26 Wuld this acknwledge nt be received, transmissin is abrted. The packet will be retransmitted upn the next transmissin interval, alng with subsequent data packets stred in internal memry. Up t 1Kb f data is stred int TBS12 internal memry befre being verwritten: depending n the prgrammed measurement and transmissin intervals, and the vlume f SDI-12 measurements t be stred (cf Data frmat), it is pssible t assess the maximum utage time withut lsing data Data frmat Each measurement stred in internal memry is time stamped, and ne packet f data crrespnds t ne sensr. As an example, if 5 SDI-12 TBSSPP1 sensrs are cnnected t TBS12, 5 packets f data are stred in memry upn each measurement interval. TBS12SMP/TBS12B/TBS12S returns 2 types f messages: - Measurement message - Battery reprting message Measurement message This message is a string frmatted as fllws: PSYY:MM:DD:HH:MM:SS:0<CMD_Index><Nb_values> Value1 Value2 ValueN Where: <PS>: packet header fr SDI-12 parameters <YY:MM:DD> is the date with <YY> being the last 2 digits f the year, <MM> the mnth number and <DD> the date. Fr example, <18:06:01> is the 1rst f June <HH:MM:SS> is the time represented as hurs/minutes/secnds, eg 16:25:00. <0>: delimiter. Nte: time is 24h frmat (ie n AM/PM representatin) <CMD_Index>: index f the SDI-12 cmmands that is executed. It crrespnds t the index f the SDI-12 cmmand prgrammed with the GUI. <Nb_values>: number f measurements returned by the SDI-12 sensr <Value1> <ValueN>: SDI-12 measurements frmatted as per SDI-12 standard (pd.d). Example: PS18:06:01:16:25: Time stamp: 1rst f June 2018 (date) 16:15:00 (time) - SDI-12 cmmand index 3-2 SDI-12 measurements returned by the sensr - SDI-12 measurements: and Battery measurement message This message is a string frmatted as fllws: PBYY:MM:DD:HH:MM:SS <Battery_vltage>Where: <PB>: packet header fr battery vltage parameter 26

27 <YY:MM:DD> is the date with <YY> being the last 2 digits f the year, <MM> the mnth number and <DD> the date. Fr example, <18:06:01> is the 1rst f June <HH:MM:SS> is the time represented as hurs/minutes/secnds, eg 16:25:00. <0>: separatr. Nte: time is 24h frmat (ie n AM/PM representatin) <Battery_vltage>: battery vltage in V cded ver 5 digit including the decimal separatr. Example: PB18:06:01:17:00: Time stamp: 1rst f June 2018 (date) 17:00:00 (time) - Battery vltage: 3.6V 4 TBS12 cnfiguratin Befre being used, TBS12 must be cnfigured: - With ad hc LRaWAN ID and ciphering keys t perate n the selected LRaWAN service prvider. - With LRa frequencies and data rates crrespnding t the area where the head is deplyed (subject t lca regulatin and as per LRaWAN standard) - With ptinal LRaWAN parameters like ADR, cnfirmed/uncnfirmed messages, - With measurement and transmissin intervals TBS12 cnfiguratin is achieved thrugh a PC applicatin that accesses the device thrugh its external UART prt. When TBS12 is cnnected t PC applicatin, its internal date and time are autmatically updated. TBS12 is designed s it can t perate until its date and time have been set thrugh the PC applicatin. A maximum f 16 SDI-12 cmmands can be prgrammed. Refer t the TBS12 PC cnfiguratin tl user guide fr further infrmatin. 5 Electrical Characteristics Current cnsumptin in sleep mde: TBS12/TBS12B: 5-7 µa TBS12S: 35 µa Current cnsumptin while perfrming SDI-12 measurements and transmitting data ver LRa depends n the kind f SDI-12 sensr(s) n ne side, and n the measurement/transmissin intervals n the ther side. 27

28 6 Pwer Management strategy TBS12 integrates autmatic pwer management feature. When the device neither measures nr transmits, the MCU ges t deep sleep mde, SDI-12 HW stage is disabled and LRaWAN mdem is in ultra lw pwer mde. Fllwing screensht mirrrs the current cnsumptin in a typical TBS12 perating sequence, where measurement and transmissin intervals ccur at the same time: the platfrm wakes up frm sleep mde, then perfrms SDI-12 measurements, and finally transmit all measurements stred since last transmissin ver LRa. 7 Mechanical Specificatins 7.1 With sil misture and temperature cells supprt (TBS12) TBS12 dimensins: 28

The default address f every sensr is ASCII[0]. When setting up a SDI-12 sensr netwrk, every sensr needs t be cnfigured with a unique address. This can be dne using the Change Address Cmmand. A sensr typically can measure ne r mre parameters. Sensr manufacturers usually specify Extended Cmmands t cnfigure r calibrate sensrs. These cmmands are specified by the manufacturer, but they fllw the cmmand structure specified by SDI-12. A typical recrder/sensr measurement sequence prceeds as fllws: 1) The data recrder wakes all sensrs n the SDI-12 bus with a break. 2) The recrder transmits a cmmand t a specific, addressed sensr, instructing it t make a measurement. 3) The addressed sensr respnds within 15.0 millisecnds returning the maximum time until the measurement data will be ready and the number f data values it will return. 4) If the measurement is immediately available, the recrder transmits a cmmand t the sensr instructing it t return the measurement result(s). If the measurement is nt ready, the data recrder waits fr the sensr t send a request t the recrder, which indicatesthat the data are ready. The recrder then transmits a cmmand t get the data. 5) The sensr respnds, returning ne r mre measurement results. SDI-12 cmmand structure: 32

33 Each SDI-12 cmmand is an ASCII string with up t 5 characters, starting with the sensr address and terminated by a! character. Example: Send Identificatin Cmmand 0I! 0 is the sensr address (sensr zer). Upn receiving this cmmand, the sensr will send an ASCII string cntaining sensr address, a SDI-12 cmpatibility number, cmpany name, sensr mdel number, sensr versin number and sensr serial number. The standard prcess t carry ut a measurement is t send a measurement request upn which the sensr respnds with the time that is required t carry ut the measurement and the number f data items being returned. After waiting the time that the sensr requires t carry ut the measurement, the data recrder sends a Read Cmmand t get the measurement results. Example: Start Measurement Cmmand 0M1! Sensr 0 might respnd which means the measurement will take 30 secnds and deliver 2 values. After min. 30 secnds, the data recrder can send the Read Data Cmmand 0D0! T which Sensr 0 might reply is the tw measurement results which may be 27 C and 1050 milibar. The respnse string f a sensr is always in ASCII frmat and may cntain up t 40 r up t 80 characters, depending n the type f cmmand. Out f 40 r 80 characters, the values part f the respnse string may cntain up t 35 r 75 characters. The respnse string f a sensr is always in ASCII frmat and may cntain up t 40 r up t 80 characters, depending n the type f cmmand. Out f 40 r 80 characters, the values part f the respnse string may cntain up t 35 r 75 characters. 9 LRaWAN netwrk basics 9.1 Overview This sectin prvides the TBS12 user a basic understanding f LRaWAN key features, s TBS12 can be integrated smthly in such ecsystem. LRa Alliance describes a LRaWAN netwrk as fllws: LRaWAN netwrk architecture is typically laid ut in a star-f-stars tplgy in which gateways is a transparent bridge relaying messages between end-devices and a central netwrk server in the backend. Gateways are cnnected t the netwrk server via standard IP cnnectins while end-devices use single-hp wireless cmmunicatin t ne r many gateways. All end-pint cmmunicatin is generally bi-directinal, but als supprts peratin such as multicast enabling sftware upgrade ver the air r ther mass distributin messages t reduce the n air cmmunicatin time. Cmmunicatin between end-devices and gateways is spread ut n different frequency channels and data rates. The selectin f the data rate is a trade-ff between cmmunicatin range and message duratin. Due t the spread spectrum technlgy, cmmunicatins with different data rates d nt interfere with each ther and create a set f virtual channels increasing the capacity f the gateway. LRaWAN data rates range frm 0.3 kbps t 50 kbps. T maximize bth battery life f the end-devices and verall netwrk capacity, the LRaWAN netwrk server is managing the data rate and RF utput fr each end-device individually by means f an adaptive data rate (ADR) scheme. 33

34 This leads then t a netwrk where each TBS12 is a unique end nde cmmunicating with a gateway as highlighted in belw schematics: Several cmpnents are invlved in the LRaWAN netwrk: - End ndes: this is any end-user device integrating a LRaWAN mdem and cmmunicating with a LRaWAN gateway. With respect t this, TBS12 is a end nde. - Gateway: it acts as a packet frwarder between end ndes and LRaWAN server. It cmmunicates thrugh LRa radi with end ndes, and thrugh a TCP/IP cnnectin with LRaWAN server (depending n the gateway capability, this can be achieved with an Ethernet, wifi r cellular cnnectin). One gateway can accmmdate thusands f end ndes, and typical range is 2km in urban areas and arund 15km in rural areas with clear line f sight. - LRaWAN server: this is a service prvided by a 3 rd party cmpany (hence the user needs t subscribe t such service). As LRaWAN packets are encrypted, the LRaWAN server prceeds with deciphering f LRaWAN packets and make them available t user s applicatin server thrugh varius cmmunicatin prtcls (this is ttally dependant n the LRaWAN service prvider, but HTTPS, WebScket and REST are widely used prtcls besides direct integratin with IT platfrms like Micrsft Azure r AWS IT). An API is then prvided t access deciphered data, device EUI and ther radi parameters (usually in JSON r XML frmat). 9.2 Integrating TBS12 in a LRaWAN ecsystem T build a private netwrk f TBS12, it is first required t chse a LRaWAN gateway (eg ) and a LRaWAN services prvider (eg ). 34

35 TBS12 is cmpatible with any LRaWAN certified gateway and netwrk service prvider. This chice is dependant n several criteria: - Gegraphic area where the sensrs will be deplyed: this determines the LRaWAN frequency plan t be used. The gateway must then have required HW t supprt these frequencies (eg 868MHz, 915MHz, etc ) - Gateway cnnectivity: depending n where the gateway will be installed, next ptins need t be cnsidered, Indr / utdr mdel Cnnectivity: Ethernet, cellular, wifi - The LRaWAN service prvider: Needs t supprt the chsen gateway (because it will be prgrammed t access the selected LRaWAN service prvider) Must supprt the frequency plans required by the user Must supprt the LRaWAN features required by the user (eg LRaWAN dwnlink, Class C, OTAA, etc ) Prvides a suitable interface fr the user s the applicatin server can cllect deciphered data (eg JSON/XML API reachable thrugh Webscket, REST, etc ) Must be ideally lcated in the same regin where end ndes are deplyed, t avid latenties (eg end ndes in Vietnam, LRaWAN server in Singapre but nt in Germany) Supprt f multiple applicatins/accunts, scalability f the server, Pricing mdel: subscriptin based, billing per gateway and end ndes, etc The next step is t activate each end nde s they are identified and can cmmunicate with the LRaWAN netwrk. LRaWAN standard defines 2 ways f activating end ndes: - Activatin By Persnalizatin (ABP): with this cnfiguratin, the end nde is bund t a specific LRaWAN netwrk. This mde is supprted by default in TBS12, and can be cmpared t a smartphne that is SIMlcked t a specific cellular netwrk. - Over the Air Activatin (OTAA): this cnfiguratin is ptinal n TBS12. It gives the end nde the raming capability, ie the end nde is nt bund t a specific netwrk, and can be re-activated n different LRaWAN netwrk thrugh OTAA prcedure. Bth activatin mdes require fllwing identifiers & keys cnfiguratin: Nte: the generatin f DevAddr in ABP mde is dependant n the LRaWAN service prvider. It can be any randm value generated by the user, r can be generated frm EUI (r ther mean) by the LRaWAN service prvider. Gd practice is t define an EUI fr an end nde, whether it is activated by ABP r OTAA. 35

36 9.3 Deplying TBS12 n the field When fitted int a husing, TBS12 s antenna shuld be external fr better perfrmances. It is key having the gateway installed as high as pssible t get increased cmmunicatin range. 10 Envirnmental Specificatins Symbl Parameter Cnditins Min Max Unit TA TSTG Operating Ambient Temperature Range Strage Temperature Range C C Humidity level Ta=60 C; n cndensatin - 95 % R.H Table 1 Envirnmental Specificatins 11 ESD Safety The TBS12 is a static-sensitive electrnic device.
