EMM001 PROBE

EMM / EMX-1

EMX-1 hardware is based on very sucesfull smart enviromental probe EMM.

Utilising multitude of acurately calibrated sensors controlled by state of the art firmware, EMX-1 Smart Probe is designed to collect precise environmental data ( ambient temperatures, dry-ice temperatures, light levels, relative humidity, atmospherical air pressure, 3D-orientation with impact / free-fall detection) and convert them to digital data.

Collected data is time / date stamped and stored into EMX's internal cyclic buffer. From there it is periodically send through serial interface to the back-end system.

If the probe is not able to transmit collected data to backend system then all the collected information remains stored in it's cyclic buffer from where it will be re-send when the communication with backend system is restored.

EMX1 is very small (20 x 60 mm). One side is consumed by 8-pin XLR connector for connection of an external PT100 sensor and serial data line. The other side is a porous plug of sintered bronze. The body is made from transparent Plexiglas. Whole device has IP40 protection degree.

HW and SW specification

• Ultra-low power consumption. Ability to operate for several minutes even when external data line is disconnected.
• Build in real-time clock and calendar. ( Proper leap year handling )
• No need for special power supply. Uses RX/TX wires for powering it's operation.
• Small in size ( 6cm x 2cm )
• All collected data is stored in internal cyclic buffer with depth of 1400 measurements. In case of buffer overrun , the oldest data is being replace with the newest data.
• Each collected record is uniquely marked with 3bytes virtual address. In case of shortest possible sampling period ( one minute ) this virtual address range should last for 31 years before overrun. The virtual address is incremented by one with each data stored into internal memory.
• Back-end system can use this virtual address as a check for transmitted data integrity. In case of missing data block, probe can be requested to re-send historical data from it's memory buffer.
• Each EMX probe has unique serial alpha-mumerical number assigned. This serial number uniquely identifies each data data packet received from probe and allows to apply customized calibration tables on the back-end side. The serial number is not only reported with each data sample send out through serial line, but as well as with every command response generated by EMX probe.
• Every time probe is reset it automatically performs internal GMT clock synchronization with the back-end system.
• It is possible to re-sync the EMX's internal clock with up-stream system any time.
• Programmable data accumulation - This parameters tells the EMX probe to hold back the data transmission until specific number of samples is collected. This accumulated data is then send to the server all at once. In case the accumulation is set to zero the probe does not send any data to the back-end system and only stores it to it's internal buffer.
• Command to remotely read-out range of historical measurement data stored in EMX's memory buffer ( based on virtual address assigned to each of the collected samples ).
• Out-of-order excursion detection settings ( upper and lower ) for light and internal temperature sensor.
• Excursion level for illumination is being checked once per 30s. ( if activated )
• Excursion level for internal temperature sensor is being checked once in a minute.( if activated ).
• 3D orientation and impact detection is monitored continually with frequency 400Hz.
• Programmable accelerometter setting. ( G-Force level detection, minimal impact duration in range 0-159ms, after impact inhibit time 0-319ms )
• In case of any excursion detection EMX1 tries to send the alert data immediately without respect to programmed sampling and accumulation parameters ( out-of-order reporting )
• Each excursion detected and stored in memory is especially marked with alert flag bit set.
• Both direction of crossing the excursion level is reported.
• If EMX does not have any collected data to be reported it does not wake up attached communication device.
• Implemented SW loader allows update of internal EMX's firmware through special USB cable without need to disassemble the probe.
• FOTA ( Firmware Over The Air ) remote FW programming allows remotely replace EMX's internal FW while attached to communication terminal.
• Watchdog security circuit - This circuit should restart the EMX1 probe in case of main SW loop lockup.
• Sophisticated power-management features - EMX1 suspends and put into sleep mode every sensor and circuit when idle or not used.
• EMX monitors safe voltage levels needed for writes into internal NVRAM memory. Under this safe levels all writes to internal FRAM memory are prevented in order to protect stored data against low-voltage-write damage.
• EMX monitors its actual power voltage. If this voltage drops under sensors safe operational levels then the probe will suspend all it's operation and will automatically reboot after safe voltage level is restored. This ability ensures defined state of operation for all on-board sensors.
• Each data environmental data send by probe is protected by data check-sum code to detect possible information damage while transmitted to back-end system.
• Ability to combine multiple data samples and commands into one data package.
• Detailed communication and programming protocols avaliable upon request
