An updated version of the ISO/TS 15143-3:2020 telematics data standard, which covers the communication schema designed to provide machinery data from a telematics provider's server to client applications via the Internet, was approved, published, and posted on the ISO website this past Jan. 29.

The new version focused on bug fixes, corrections, and some clarifications to the first version, which was published in December of 2016. These much-needed improvements have helped provide some clarity to new adopters of the standards by removing some of the “gray areas” and minimizing areas that could be interpreted multiple different ways.

In addition to the clarification, a few new items were also added to the telematics data standard. Those include data element use cases, time series schema, and the biggest change, a process for adding new data elements.

The ability to add new data elements to the standard gives data providers and data consumers a way to propose and, if approved, include data specific to certain types of machines. An example of this, and one that a group of manufacturers of Mobile Elevating Work Platforms (MEWPs) had discussed, would be to capture the maximum (or average) a boom lift was extended on a given day. This would provide end users, or rental companies, a way to understand if a properly sized machine is on the jobsite. If an 80’ boom only extends to 25’ consistently, the user may be able to rent a smaller machine or move the higher reach capacity machine to an area where it’s needed.

Another advantage of allowing the standard to be appended to is the ability to adapt the available data to keep up with changes in the market. One of the data elements that is anticipated to be proposed in the near future, especially with all of the electric equipment on display at CONEXPO-CON/AGG, might be “battery health.” Instead of equipment having an internal combustion engine (which there are currently multiple data elements related to), it may be powered by something else, such as a battery. Fleet managers and technicians will want to know things like if the battery is charged, similar to the existing data element of “fuel remaining.”

Future Clarifications and Changes

Although the changes that took effect in the 2020 version are a great step in the right direction, there are still many areas where the standard could become more specific. AEM’s Telematics Subject Matter Expert Committee met recently to discuss challenges with utilizing machine data. Although some of the challenges with obtaining telematics data from equipment isn’t directly related to the ISO Standard, the committee agreed that there are additional improvements that can be made to the standard. This is especially the case as more machines are released with telematics capabilities from the factory and connectivity challenges will continue to diminish as cellular networks improve.

The standard needs to allow some leeway, as data providers are using different systems internally, although should be streamlined enough to ease some of the development challenges for anyone, third parties or end users, who is trying to ingest data feeds from multiple providers. The committee is working to try to find the right balance and adapt the standard to limit implementation challenges.
