[0042] According to an embodiment of the present invention, there is provided a edge device 100 shown in Figure 1 for logging data in remote locations and under harsh environmental conditions which require long-term, low-maintenance operation. The edge device 100 is portable and able to be carried by hand. The edge device 100 is used to record measurements (device and sensor telemetry) and events before sending this information via cellular, wireless or satellite technology to a cloud platform for monitoring and management purposes.

[0043] The edge device 100 includes a lower electronics module 102. The edge device 100 also includes an upper battery module 104 for releasably fastening to the electronics module 102 to power the electronics module 102.

[0044] Advantageously, the electronics module 102 and battery module 104 are both exposed, and the battery module 104 can be readily released from the electronics module 102 during its replacement, without the need to internally access the electronics module 102, thereby providing for quicker and safer battery replacement than known methods. For ATEX / International Electrotechnical Commission for Explosive Atmospheres (lECEx) versions of the product, the battery module and electronics module has an ATEX rated design for use in Zone 0, 1 and 2. This includes the ability to perform battery replacements within these zones, without the need to action outside of these zones. With the standard and ATEX rated versions. The enclosure of the battery module 104, and electronics module 102 and internal electronics, are rated ATEX / IECEX to support Battery Replacements in ATEX zone 0, 1 and 2 areas allowing battery replacement to occur in these zones, without the need to exit the zone area.

[0045] simple field battery module replacements typically take less than 30 seconds whilst retaining edge device IP waterproof rating prior and post replacement of the battery module 104. The simplified battery replacement process ensures no need to utilise specialist tools or complex work instructions to access internal components whilst completing a battery replacement in the field. The edge device integrity and environmental protection is maintained whilst performing battery replacements.

[0046] The battery module 104 threadably engages to twist and screw fasten with the electronics module 102. The plastic housings of the electronics module 102 and the battery module 104 include undulating gripping formations 106, 108 to facilitate rotation as the electronics module 102 and the battery module 104 are axially fastened together to from an elongate unit. The edge device 100 includes a pair of O-ring seals 1 10 for locating at the threaded interface and sealing between the electronics module 102 and the battery module 104.

[0047] The battery module 104 also includes a recessed terminal plug 112 for engaging within a socket 114 of the electronics module 102 during fastening. The electronics module 102 also includes an underside connector interface 116 for interfacing with one or more connectors wired to external devices such as sensors.

[0048] The battery module 104, which is distinct from the enclosure of the electronics module 102, allows for 'plug and play' battery module replacements in the field in less than 30 seconds, without compromising IP waterproof protection.

[0049] Batteries are housed in a separate enclosure of the battery module 104, which is affixed to the top of the electronics module 102 via multiple clockwise rotations of the battery module 104 onto the enclosure of the electronics module 102. Once the contacts of the battery module terminal plug 112 (male) meet the contacts of the electronics module terminal socket 114 (female), the electronics module 102 and battery module 104 lock and form a seal based on the double O-ring 110. Upon connection of the electronics module 102 and battery module 104, the battery module 104 is now able to power the electronics module 102 operating according to its configuration parameters.

[0050] Turing to Figure 2, the edge device 100 includes a connector protector 200 for protecting connectors 202 connected to the connector interface 116. The connector protector 200 includes a cap-like cover 204 for covering the connector interface 116. Theconnector protector 200 also includes an O-ring seal 206 for sealing between the connector interface 116 and the screw fastened cover 204 so that the edge device 100 is waterproof.

[0051] The connector protector 200 also includes a cable fastener 208 for fastening to one or more cables 210 and connectors 202 extending from the base of the electronics module 102. Figure 2C displays a product variant with two LTE SMAs 210 and two M12 connectors 202. Other versions within the suite may have a different combination of these, but as a minimum, at least one SMA cable 202 and one M12 connector 210 . The cable fastener 208 provides cable strain relief, and seals against the cables 210 and connector 202 to further impede moisture ingress and corrosion, as well as vermin damage. The cable fastener 208 includes a pair of outer retainers 212A, 212B for retaining a pair of inner resilient seal members 214A, 214B between which the cable 210 and connector 202 passes. The lower retainer 212A extends from the cover 204, whereas the upper retainer 212B is screw fastened to the lower retainer 212A.

[0052] This protector 200, which affixes to the bottom of the electronics module 102, minimizes risks associated with vermin damage and hazardous corrosion around the connectors 202 and cables 210 particularly when the edge device 100 is in a sewer or wastewater use case environment which contain a high concentration of dangerous gases and corrosive liquids, including hydrogen sulfide, hydrogen chloride and methane. Additional protection is already achieved with the utilisation of Stainless Steel 316 connectors 202 to ensure high resiliency and protections against chemicals listed above when deployed in hazardous environments.

[0053] As best seen in Figure 2B, the connector protector 200 effectively forms an additional IP waterproofing seal over the connector 202 and 210 that impedes these harmful substances from coming into contact with the edge device's external connectors 202 and cables 210, whilst also minimising the exposed connector ends and wires accessible to vermin. The protector 200 serves a further purpose by providing effective cable management allowing cables 210 and connectors 202 to move north or south axially aligned with the elongate edge device 100 and a mounting bracket for mounting the edge device 100.

[0054] Turing to Figure 2C, 2D and 2E, where the protector 200 is removed, the edge device 100 includes the standard mounting bracket 220’ which can be utilised fordifferent mounting options. Mounting options include the ability to mount to a wall 250 (Fig. 2D), pipe / pole 252 (Fig. 2E) or internal cabinet 254 (Fig. 2F). As displayed in:• Figure 2D, the edge device 100 can be mounted via two bolts 256 ed to a wall 250.• Figure 2E, the edge device 100 can be mounted via two steel hose clamps 258 to a pipe or pole 252• Figure 2F, the edge device 100 can be mounted via four screws 260 to an internal cabinet wall 254

[0055] The mounting bracket 220 of Figure 2C includes a base 224. The mounting bracket 220 also includes two resilient arms 226 extending from the base 224 which from a receiver for receiving the electronics module 102 of the edge device 100. The edge device must be removed from the mounting bracket to perform battery replacement The edge device 100 can be seated into the mounting bracket 220 and rests on a lip 228 of the electronics module 102. Two screws are used to fix the edge device 100 (combined battery pack 102 and electronics module 104) to the mounting bracket 200 (NUMBER TBC). on product variant in use or use case deployment. The arms of the mounting bracket 220’ define a tabbed base 256 upon which the device 100 sits and opposed pronged receptacles 258 for receiving housing fins of the device 100.

[0056] Other mounting bracket options specific to use case deployments product suite variant are available which includes additional capabilities such as release catch mechanisms and additional sensor brackets incorporated into the device bracket.

[0057] Turning to Figure 3, the electronics module 102 includes a wireless communications module 300, with transceiver, for transmitting telemetry data to a monitoring station. The communications module 300 includes two Subscriber Identity / ldentification Module (SIM) cards for redundancy to impede communications interruption. The electronics module 102 can automatically switch between the SIM card providing greater flexibility and reducing reliance on single network operator via eSIM, whilst providing a backup connectivity option if required.

[0058] The edge device 100 includes onboard sensors 302A which are onboard the electronics module 102 and external sensors 302B which interface with the electronics module 102 via the connector interface 1 16. The electronics module 102 includes a processor 304, controlled by software 306, for processing sensor data from the sensors 302A, 302B. The electronics module 102 also includes a storage device 308 for storing telemetry data from the sensors 302.

[0059] The edge device 100 includes an onboard antenna 310A which is onboard the electronics module 102, and an external antenna 310B which interfaces with the electronics module 102 via the connector interface 116. The antennas 310A, 310B are coupled to the communications module 300.

[0060] The electronics module 102 also includes an onboard auxiliary battery 312 to power the electronics module 102 for a short time after disconnection of the main battery module 104.

[0061] The edge device 100 is now described in more detail. The battery powered edge device 100 autonomously collects data from its environment using sensors 302A, 302B, analyses data onboard using the processor 304 before transmitting this data using the communications module 300 to a single or multiple cloud endpoints for analysis, storage, or real-time monitoring. This functionality is achieved whilst operating in remote and harsh environmental conditions and operating on low powered non-rechargeable or rechargeable batteries in the battery module 104.

[0062] The edge device 100 performs the following general operations:• Data Collection - Any internal sensors 302A or external sensors 302B connected to edge device 100 continuously or at set intervals will collect data from their environment based on defined configuration. This can include monitoring conditions like temperature fluctuations in a cold storage facility or measurement of water usage in commercial metering use cases.Data Processing - Once the data has been collected from the sensors 302A, 302B, the processor 304 (e.g. microcontroller) processes this raw data including filtering and sanitisation with the ability to encrypt the data (if use case requires). Theprocessor 304 will also process data and highlight any repeated values to support more optimised transmission.• Data Storage - The onboard storage device 308 is able to store at least 5 years of data. This storage operation enables multiple measurements from the sensors 302A, 302B to be captured prior to transmission based on configured send interval. This functionality is important when the edge device 100 is unable to send due to poor communication network coverage or other reasons preventing a successful connection to the network. This ensures the edge device 100 can continue to collect data whilst reattempting to connect via the network to the cloud platform.• Data T ransmission - The edge device 100 periodically transmits the stored data to a designated server or cloud storage via its communications module 300 based on its configured send interval parameters. Transmission can also occur based on alternate logging schedules and alarm triggers.• Data Analysis / Real-time Monitoring - This functionality primarily is achieved using the firmware and software of the processor 304 and a device of a monitoring station that the edge device 100 connects and transmits data to. A remote monitoring system includes the monitoring station for monitoring data transmitted from the edge device 100.• Customers using Captis Series 2.0 will leverage this functionality to view and monitor the device data and health status, manage the device via device management tools and potentially integrate with upstream / downstream business and operations platforms to support process automation.

[0063] The components of the edge device 100 include:• Sensors 302A, 302B - These are the primary components that capture data from the environment. The edge device 100 can support connections to external sensors 302B via digital inputs, analogue inputs, and digital interfaces including serial protocols such as Modbus (2 RS485), and 1 -Wire. The edge device 100 operates with both self-powered sensors 302A, and external sensors 302B requiring external power and that the edge device 100 can supply via the connector interface 116, configurable voltage up to 24V. The internal sensors 302A includean embedded temperature sensor, and accelerometer. The internal sensors 302A can also include a microphone, submersion sensor pressure sensor, humidity sensor, and light sensor.• Processor 304 - Responsible for processing the data collected by the sensors 302A, 302B, performs preliminary computations, and prepares the data for transmission. The processor firmware utilises a Real-time-operating-system (RTOS) to ensure the edge device 100 can handle concurrent processes with no loss of critical functions or events. As an example, the edge device 100 can detect signals from multiple sensors 302A,302B and upon receipt of signals, trigger and action specific functions within the edge device 100 at the time they need to be actioned and run. In addition, the processor 304 enables low power machine learning, also called TinyML, allowing data to be processed at the edge (i.e., physically on the edge device 100), which is useful in supporting process alarm functionality. TinyML functionality enables the device to detect and interpret more complex sequences and / or patterns in the collected data, before triggering a process alarm and / or other function on the edge device 100 based on rules maintained in the edge device 100 configuration.• Device Memory Storage 308 - This is used for temporarily storing the data collected by the sensors 302A, 302B before it is transmitted or while awaiting processing. The edge device 100 is able to store on-board the device at least 5 years of data based on 15minute logging intervals and 10 measurements (excluding events and device health). This can also be extracted locally via USB by the manufacturer if the enclosure of the electronics module 102 is opened.• Battery Module 104 - the battery module 104 affixes to the enclosure of the electronics module 102 to power the electronics module 102. The battery module 104 can be either non-rechargeable or rechargeable and ATEX or Non-ATEX rated (for use in Atmosphere Explosive environments). The rechargeable battery pack variant can be charged from either a DC power supply or solar cell. The non- rechargeable battery module 104 utilises Lithium thionyl chloride batteries whereas the rechargeable battery module 104 utilises Lithium-Ion batteries. The non-rechargeable battery module 104 caters for single, two cell, and four cell , ATEX and Non-ATEX configurations, based on different usage durations. ForATEX battery module variants, the module 104 is designed and rated for intrinsic safety with applicable circuitry limits in place. In addition, the contacts between battery module 104 and electronics module 102 have been de-energized if the battery is not fully engaged, preventing accidental discharge and enhancing safety, whilst current limiting fuel gauge is configurable to limit output between 5mA and 100mA providing operational protection beyond intrinsic safety requirements. Finally, the electronics module 102 is designed to accommodate emerging battery technologies without the need for product redesign, ensuring longevity and adaptability of the edge device 100 in the future.• Communications Module 300 - The communications module 300 enables the edge device 100 to connect to a network. For example, the edge device 100 utilises a cellular module and embedded SIM to transmit the collected data to a cloud server via a cellular connection on LTE-M (Cat-M) or NB-loT. The communications module 300 has the functionality for two SIMs and the ability to switch between them. Future variants will utilise multiple modules to provide additional connectivity via Satellite or LoRaWAN, including hybrid options i.e. a combination of both or with cellular.• Antennas 310A, 310B - The edge device 100 supports a built-in internal antenna 310A (included in the electronics module 102), and the ability to connect an external antenna 310B to the electronics module 102 via LTE SMA connector at the connector interface 116. Firmware of the processor 304 can be configured to select preferred antenna 310A, 310B with the edge device 100 able to automatically switch and fallback to alternate antennas 310A, 310B as required (e.g. based on signal strength).

[0064] The edge device 100 performs the following routines:• Power Management - The edge device 100 can optimise the total battery life time of the battery module 104 by dynamically scaling the energy consumption depending on the operating mode and workload, range of sleep modes, predictive current draw limiting, partial power disconnection, operating voltage control and wide input voltage range allowing full utilisation of the chosen battery chemistry.• Battery Management - The edge device 100 can track the real battery usage of the battery module 104 through the combination of hardware and software means for both rechargeable and non-rechargeable batteries.• Remote Configuration and Updates - The edge device 100 can be remotely configured or updated, allowing users at the monitoring station to change edge device configuration settings like data collection intervals as well as updating the edge device 100 and firmware remotely over-the-air (OTA). This can be conducted via the communications module (cellular, satellite or LoRaWAN), mobile near field communication (NFC) and / or Bluetooth.• Tamper Proofing - The electronics module 102 uses a proximity sensor to determine tamper alerts based upon release of the battery module 104 from the electronics module 102. The edge device 100 incorporates tamper alarms functionality that trigger upon enclosure opening (separation of the battery module 104 from the electronics module 102) and sends an alarm to the cloud platform enhancing edge device security.

[0065] To ensure the monitoring station can monitor and audit separation of the battery module 104 from the electronics module 102, embedded firmware of the electronics module 102 determines when a battery module 104 is removed and attached to the electronics module 102. This involves recording of the battery module serial identifier (ID) and event timestamps when this removal or attachment occurs. This data is stored in the onboard storage 308, and is also transmitted to the cloud and maintained in the management platform against the device at the monitoring station. Accordingly, a record is kept on all battery module replacement events during the edge device’s life whilst deployed in the field ensuring full visibility and traceability.

[0066] The tamper proofing handled via a battery module replacement Red, Amber, Green (RAG) status which is stored on the electronics module 102 and also sent to the cloud. The RAG status whilst configurable are defined by default as follows:• Red - Battery module 104 is removed and not replaced, and edge device 100 goes offline. This is verified by the edge device 100 not communicating for >24 hours. Edge device 100 will send tamper status when new battery module 104 is connected.• Amber - Battery module 104 is removed and replaced, though not in the configured time allocation so tamper alarm is triggered. When battery module 104 is replaced, this is also sent to monitoring station.• Green - Battery module 104 is removed and replaced within the configured time allocation. No tamper alarm triggered but a battery replacement event is triggered.

[0067] Noting the edge device 100 will require power to be able to support communication of this RAG status to the cloud and monitoring station, the edge device 100 includes a ‘last gasp’ battery charge which is retained in the onboard auxiliary battery 312, ensuring that when the battery module 104 is disconnected from the electronics module 102, if a replacement battery module 104 is not connected in required time, the electronics module 102 can trigger a final power up of the module 300 and attempt to send a transmission to the configured server location of the monitoring station (i.e. via the cloud platform highlighting a potential tamper battery alarm event). This event is also retained in the device memory should the device 100 fail to send a transmission to the cloud, so if the device 100 is retrieved from the field this can be reviewed by the manufacturer when connecting to the device 100 via USB and retrieving the device logs stored in the memory.

[0068] As briefly described above, the edge device 100 has “plug and play” functionality to seamlessly integrate with 'Plug & Play' external sensors 302B, via use of a smart sensor cable 202. The electronics module 102 automatically detects connection of a connector 202 to the connector interface 116, and is then configured to operate with the external device (e.g. sensor 302B) to which the cable 202 is connected, thereby providing for improved interfacing of the device. In this manner, the electronics module 102 allows a default configuration to be applied in operating with the newly interfaced device, and enables ‘plug and play’ interfacing of external sensors 302B.

[0069] To enable this, the processor 304 is programmed to automatically detect the connection of the smart sensor cable 210 and the attached sensor 302B (or multiple sensors) via a M12 SMA socket on the connector interface 1 16 of the electronics module 102. The sensor recognition via this smart cable 210 enables the subsequent automated configuration processes handled by firmware of the processor 304.

[0070] Upon the initial connection of a sensor 302B, the processor 304 automatically applies a pre-set default configuration from a stored list of pre-approved sensors 302B and configurations which is maintained in the firmware. This streamlined process ensures that the sensors 302B are operational with minimal setup time, enhancing efficiency in the field.

[0071] While the processor 304 applies a default configuration to each connected sensor 302B initially, it also supports the flexibility for users at the monitoring station to modify these settings via the cloud management platform. This feature allows users to tailor and override the default sensor configuration applied based on their specific requirements and / or environmental conditions applicable to the use case. Once a user has modified the sensor settings, the edge device 100 is designed to maintain these configurations persistently. It will not revert to the default settings unless explicitly instructed by the user for the given sensor 302B. This ensures that user preferences and operational parameters remain consistent across uses, providing reliability and predictability in sensor performance.

[0072] The 'Plug & Play' capability simplifies the process of sensor integration, making it straightforward for users to deploy and manage their sensor networks effectively. The emphasis on automatic detection and configuration, coupled with the flexibility for user-defined customisation, positions the edge device 100 as an effective solution in sensor technology and loT device integration.

[0073] The dual SIM functionality enhances the edge device’s connectivity and reliability in diverse operational environments, providing greater flexibility and reducing reliance on a single network operator via the use of an eSIM. Additionally, backup connectivity is an option if one of the SIMs fail or the local regional network operator physical SIM is preferred.

[0074] The communications module 300 accommodates two nano, or MFF2 SIM cards, of which one will be an eUlCC SIM (eSIM) capable of supporting multiple global network connectivity profiles and the other a standard regional network operator. The electronics module 102 provides the ability to preference multiple network connectivity providers on SIM 1 (via the eSIM), with the ability to switch to the alternate SIM 2 (standard SIM) controlled by firmware of the electronics module 102. In terms of switching, this can occur either manually via a command and configuration updateissued to the edge device 100, or automatically based on specific edge device health status and events.

[0075] Firstly, manually switching the SIM card can be triggered via a command and configuration update. The configuration update and command will be issued to the edge device 100 via the device management cloud platform of the monitoring station. Upon taking the command and updated configuration successfully, the edge device 100 will switch SIM and attempt its scheduled connection via this alternate SIM. Should the edge device 100 fail to connect to the network via this alternate SIM, after three attempts the edge device 100 will fall back to last known good configuration and attempt to connect via the initial SIM. This feature grants users the flexibility to select their preferred network based on organisation preference, cost considerations, or network performance. It offers a high degree of control over network selection, allowing for a customised and situation-specific connectivity solution, whilst providing redundancy to fallback to previous SIM if device fails to connect to the network.

[0076] Secondly, automatic switching, the edge device 100 is equipped with the intelligence to automatically prefer one SIM card over another based on a set of defined edge device health parameters and events, either configured as a default setting within the edge device firmware and then configurable via the edge device management platform. Similar to the above method, a configuration update and command is issued to the edge device 100, although this time without user intervention. Upon taking the command and updated configuration successfully the edge device 100 will switch SIM and attempt its scheduled connection via this alternate SIM. Should the edge device 100 fail to connect to the network via this alternate SIM after three attempts, the edge device 100 will fall back to last known good configuration and attempt to connect via the initial SIM. This capability ensures that the edge device 100 can autonomously switch to the most optimal network under varying conditions such as signal strength, data usage, or network reliability. This automated process is designed to optimise the edge device’s functionality and ensure consistent performance without user intervention.

[0077] The Dual SIM functionality of the edge device 100 provides a significant advancement in loT device connectivity. Th dual embedded SIM provides the ability to switch primary network provider if the user has a preference or existing account viaeSIM. The communications module 300 includes a back up SIM if this fails avoiding the need to insert a physical SIM and risk IP waterproof rating.

[0078] The edge device 100 has a robust industrial design, meticulously tailored to withstand extreme environmental conditions and harsh operational scenarios. These conditions include settings where the edge device 100 might come into contact with environmental moisture, dust particles, harsh chemicals and even water submersion, and still be required to operate as required for the edge device lifecycle of 10-15+ years. The edge device 100 operates within the following temperature range of -20°C to +70°C and humidity range of 5% to 95% non-condensing. The edge device 100 also caters for protection from external environment and possible submersion and is designed to meet IP68 rating.

[0079] The releasable fastening of the battery module 104 to the electronics module 102, and the connector protector 200, avoid such incursion having the potential to harm the internal electrical components of the edge device 100, which could drastically reduce its expected lifespan and its operations.

[0080] For scaled deployments considering the business case dynamics, where battery replacement cost and complexity are required to be factored in during the life of edge devices, it is often likely a customer will replace the edge devices as opposed to maintaining and replacing them the field. The edge device 100 is, in most instances, more cost efficient due the longer expected operational life and reduced field replacement time. Servicing the edge device 100 in remote locations is made easy by simply releasably fastening the battery module 104 to the electronics module 102 to power the electronics module 102.
