For some users, having a simple notification or alert when a certain condition exists, is all the remote monitoring they want. For example, there are compliance requirements in many industries where if something is too full, too empty, too high, too low, an item has gone active, or an item has failed that someone needs to be notified quickly in order to protect people and property. In many of these cases the monitoring of the devices is done manually by workers and volunteers checking the status regularly and in many cases recording and reporting the information via paper logs to clerks or managers who transcribe the logs and record them electronically. Depending on the regularity, consistency, and accuracy of the manual checks, compliance may or may not be achieved. These manual “costs” may be quite high when calculated over a year’s time. If the manual checks are not accurate or consistent, the failure to meet compliance can “cost” many orders of magnitude more than the costs of the manual checking. With remote wireless monitoring, checks can be done as frequently, consistently, and accurately as desired. Most importantly, alerts and notifications can be generated automatically when specific conditions exist such that the situation can be addressed before it becomes non-compliant. Alerts and notifications can be as simple as an SMS or email.
Simple Manual Monitoring that could be Remote Monitoring
Many applications that require manual monitoring today already have electrical equipment and/or sensors in place that can be converted simply and inexpensively to remote monitoring. For example, water levels are measured by sensors that provide a digital reading representing the current water level – this is recorded manually by a worker or volunteer who checks the reading every day (or more frequently when it is raining) and records the level in a log book. The person takes the log book and hands it to a clerk (or calls it in to a clerk, or sends via email, etc.) where the clerk enters it (hopefully accurately) into a spreadsheet or perhaps a corporate data system. The spreadsheet or corporate system is then used by a manager or director to compile the reports that demonstrate that all of the items are being checked regularly to meet compliance, measurement, and/or other requirements. These types of checks are regularly done for other risks as well – liquid levels that may be too low/high, pressures that are too high/low, temperatures too high/low, timings too long/short, equipment that is on/off, and many others.
Simple Connections to Inputs and Outputs
For most of the items being checked manually there is an electronic means of detecting the range of values that need to be reported and recorded. In some cases, the electronic “sensor” is as simple as a switch (similar to a switch in a toilet tank that turns off the water when the tank is full – we count on these every day!). Similar, but more complex switches may have multiple “positions” that change based on the level of fill. Even more complex switches generate electrical signals that vary within the range of things they are measuring. Many sensors do not directly display the measurements in a human readable form, but instead provide electrical information proportional to the thing being measured. Other sensors have simple indicators (red/green), digital displays, or even more sophisticated interfaces. For sensors that provide digital or analog outputs, connecting them to Cellio is simple and inexpensive. Cellio provides screw terminals where the wires from the sensor(s) can be directly connected into the Cellio Transceiver and the readings collected and transmitted as frequently as desired.
Simple Alerts and Notifications
Based on collected data, whether from other cloud services or from sensor readings, alert and notification (SMS, email, HTTP posting, etc.) conditions can be set to notify any and all personnel who need to receive notifications in whatever means they need to be notified. In the case noted above, assuming that a “high water mark” was detected, Cellio would have reported the reading or sent a triggered report through the network to the back-end where it would have been evaluated against the set criteria and the relevant alerts/notifications/messages would have been sent to designated people, processes, and possibly other data systems to notify them of the measurement and “out of bounds” condition. If the water level were to rise even higher and another level was measured that indicated an “emergency level”, that measured level would also be sent or would have generated a triggered report that might set off a different set of notifications, to a different set of people, processes, or data systems to deal with the new condition. Similarly, if the water to fall below the high water mark, a new alert might be sent to “call off” the alert condition and return the status to “normal”. All of the conditions, alerts, notifications, and integrations are configurable through Cellio.
Bonus: As Much Complexity as You Need
Cellio’s integrated connectivity and back-end services provide all the tools necessary to view the collected data via graphs, tables, summary data, calculated values, estimates, analytics, and even sending and receiving data to enterprise systems or other cloud data services. These capabilities make the evolution from simple alerts and notifications to highly sophisticated analytics, forecasting, and integration to larger enterprise systems inexpensive and relatively easy. You choose the complexity that you want when you want.
The Cellio Wireless Network has been designed to be as quick, affordable, and high quality. Cellio Wireless Transceivers allow the Cellio system and customers to quickly and easily expand existing systems with as many sensors and controllers as they like (with minimal incremental expense). The data collected in the back-end data system can be easily and rapidly mapped and provided for view on PC’s, tablets, smartphones, etc. both via browser views as well as automatically generated native mobile app views. Sharing and modifying the dashboard views is quick and easy. All of this is available and easy to put in place today. There is a saying that you should “Inspect what you expect”. The rules around notifications and alerts are something that should be considered intentionally and deliberately. Who gets the notifications, how they get them, how frequently they get them, and what they are supposed to do in response to getting them will have a profound impact on the value of receiving them- implementing these decisions is where Cellio really shines.
At the simplest level, we have had customers get an IIoT system from sensors to alerts/notifications set up in less than half a day.
