TALQ Consortium to Introduce TALQ Version 2.0 Standard for Smart City Applications

The TALQ Consortium, which developed a global interface standard and certification system for managing outdoor lighting, announced that it will soon introduce TALQ version 2.0, an easy to integrate RESTful/JSON protocol. TALQ version 2.0 addresses numerous smart city applications. According to the consortium, the updated technical specification defines the new state-of-the-art Smart City Protocol and gives manufacturers full flexibility to establish their own devices and functionality as desired. Furthermore, TALQ version 2.0 ensures cities and municipalities broad interoperability of numerous smart city applications from different vendors.

Cities around the world that are working to becoming smart cities face the same issues including implementing advanced smart lighting, waste management, parking, traffic control and many other services in ways that strive to save energy, reduce traffic, increase security, and improve quality of life. The consortium notes however that currently, most available solutions are proprietary. These proprietary systems lock cities and municipalities into single vendor solutions.

The consortium insists that with the TALQ Smart City Protocol, cities will be able to select and adopt solutions from multiple vendors. These solutions can all be controlled via a single Central Management System (CMS). The Smart City Protocol, TALQ version 2.0, serves as an application interface to exchange data, commands and programs between one or more CMS and Outdoor Device Networks (ODNs) from different vendors to enable configuration, control, management, and monitoring of connected devices in the city.

TALQ Version 2.0 More Flexible with RESTful

The updated protocol, which the consortium intends to publish in summer 2018, defines the message types, data format, parameters and behavior of CMS and Gateways. In so doing, TALQ does not limit the types of network deployments in the ODN itself, but specifies the interface between the Outdoor Device Network’s interface (Gateway) and the Central Management System.

The new version 2.0 is based on a bidirectional RESTful API with JSON-LD data payload that utilizes underlying standardized data transport, network and security services including HTTP, TLS, TCP and IP, to establish communication between CMS and Gateways.

The standard RESTful approach, adopted by TALQ, makes integration easy for makers of smart city applications in existing Central Management systems and Gateways. To provide configuration, control, command and monitoring services, the TALQ Smart City Protocol supports HTTP REST GET, PUT, POST, PATCH and DELETE requests on REST resources including devices and services.

TALQ Version 2.0 Makes Getting Real-time Values for CMS Software Developers

The consortium asserts that TALQ version 2.0, getting log values (such as temperature, voltage, current, energy usage) from devices, reading real-time values from a device, and sending configuration parameters to a device or remote controlling it, becomes obvious for CMS software developers.

“Our clear goal is to make it easy for cities to connect any smart city device to their CMS, so that any data produced is stored and displayed and can be used in any other Smart City processes and applications, explained Simon Dunkley, secretary general of the TALQ Consortium.

The consortium says that TALQ implementation, vendors are free to define their end-devices through TALQ Functions (i.e. sets of agreed attributes and events) which can be configured, controlled and monitored utilizing TALQ services which include configuration, data collection, real-time control, on-demand senor read, scheduled control, etc. In this way, the consortium says TALQ promotes competition and lets cities choose among multiple different solutions while ensuring compatibility of all different systems.
