Final Report Summary - SAFEPHONE (The development of an intelligent, self physical condition monitoring, illuminated, telephone casing for use in hazardous, arduous or safety critical environments)

The SAFEPHONE project aimed to complement the corpus of recent research studies concerning Pan-European road transport safety and the proliferation of vehicular telematics, exploiting the growing array of communications architectures technologies. Utilising the extensive networks of emergency telephone infrastructure already in existence, Safephone aimed to support a stepchange in the personal safety of the travelling public, cost-effectively, enhancing security and communications systems integrity.

The scientific objective of the project was to enhance the scientific understanding of the capability of a piezoelectric device, by building a working prototype device that demonstrated:
- Remote self-powered monitoring of a single composite component when encapsulated during the enclosure forming process.
- The capability of the embedded piezo device to power low level component illumination provided by embedded fibre optics.
- A low-powered (approximately 8 mW), fieldbus compatible, electrical signal system to enable remote diagnosis monitoring of the piezo generated signal within the casing.

The technological objective was to extend the use of piezoelectric devices into two other safety critical products e.g.:
-To develop a recyclable, single material composite for the manufacture of telecoms enclosures that met IEC 60529 Standard IP 67 rating communications casing.
- To develop and embed, low-powered fibre-optics into the housing to provide in-case illumination.
- To develop and embed a piezoelectric impact monitoring device into the telephone casing, reducing by 100 % the need for manual inspection of the enclosure.
- To develop a low power (minimally sub 2 mA) signal-generation allowing for compatibility across the emerging digital telecoms infrastructure.
- To develop an electronics control system package that would manage signals from the piezo embedded enclosure via the Phone and landline system to a central control function, improving system integrity by 20 %.

The societal and policy objectives were the following:
- To reduce by 100 % the unnecessary exposure of routine maintenance staff to hazards from passing traffic by eliminating the need to carry out routine inspection of the system.
- To increase the reliability of emergency telephones by 50 % through the introduction of remote routine monitoring of the telephone housing for damage.
- To increase employment in the EU, by creating approximately 2 000 jobs through value added to the product functionality resulting in lower product lifetime costs and product differentiation from low-cost, non-EU sources.
- To increase recyclability of the enclosure material by 70 % and addressing the recent WEEE directives on waste production.

The economic objectives of the project were the following:
- To reduce the end of life disposal cost through increased recycle-ability and increased life span of the product.
- To incorporate the value added features of self illumination and self diagnosis to the emergency telephone housing system.
- To develop a single material product for the casing that can be injection moulded to different levels of the IP standard at a reduced cost to current product materials.
- To reduce the resources needed in operating routine preventative maintenance programmes for Highway Emergency Telephone Systems by focusing maintenance attention only on those Phones which need to be repaired.

The following research and development work was required to achieve the technical objectives:
- Remote self-powered monitoring of a single composite component when encapsulated during the enclosure forming process.
- The capability of the embedded piezo device to power low level component illumination provided by embedded fibre optics.
- That a low-powered (approximately 8 mW), fieldbus compatible, electrical signal system to enable remote diagnosis monitoring of the piezo generated signal within the casing.
- To develop a recyclable, single material composite for the manufacture of telecoms enclosures that meets IEC 60529 Standard IP 67 rating communications casing.
- To develop and embed, low-powered fibre-optics into the housing to provide in-case illumination.
- To develop and embed a piezoelectric impact monitoring device into the telephone casing, reducing by 100 % the need for manual inspection of the enclosure.
- To develop a low power (minimally sub 2mA) signal-generation allowing for compatibility across the emerging digital telecoms infrastructure.
- To develop an electronics control system package that will manage signals from the piezo embedded enclosure via the Phone and landline system to a central control function, improving system integrity by 20 %.

The work that was carried out during the project was divided into seven work packages.

WP1: Scientific Characterisation: This work package combined the base information in providing the optimum type, number and locations of piezoelectric devices to be bonded to the telephone enclosure moulding which would enable effective remote diagnosis of the enclosure condition.

WP2: Impact Sensor: In this work package the definition and development of an Impact Sensing algorithm capable of identifying the position (to within 3% in each axis of the object’s surface area) and relative projected damage of an impact on a hollow object whose shell is of varying material strength, density and shape was undertaken.

WP3: Remote Diagnosis: In this work package it was proposed to develop the remote diagnosis and management communications module in association with a centralised control system.

WP4: Integrated Device Design: The objective of the work package was to develop the enclosure by specifying the requirements of the application. A robust method of holding the optical sub-system, developing a self-cleaning surface finish and selecting the components and lay-up of the composite bulk material would be developed.

WP5: System Integration: In this work package a design for an integrated system that demonstrated the integrated functionality of the system was developed. Prototype components were produced and an integrated prototype system was created.

WP6: Innovation Related Activities: In this work package the project results were formulated into a protect table form.

WP7: Coordination Management: In this work package the objectives were to ensure that all knowledge was created, managed and disseminated in a coordinated and coherent manner, along with all technical activities, legal aspects and other issues. A dissemination and use plan to aid the dissemination and exploitation process would be developed as part of the work package.

The achieved results of the project were the following:
- Developed and embedded a low-powered lighting technology into the housing to provide in-case illumination that doesn’t negatively affect the results of the damage location algorithms.
- Developed a low-powered (approx 8mW), electrical signal system to enable remote diagnosis monitoring of the piezo generated signal within the casing.
- Developed the capability of the entire system (including the low power illumination technology, the piezo devices and the additional logic and communications electronics) to be powered by current standard power inputs for VoIP emergency telephones.
- Developed a recyclable, single material composite for the manufacture of telecoms enclosures that meets IEC 60529 Standard IP 66 rating communications casing.
- Developed and embedded a piezoelectric impact monitoring device into the telephone casing, reducing by 100% the need for manual inspection of the enclosure.
- Developed a low power (minimally sub 2mA) signal-generation allowing for compatibility across the emerging digital telecoms infrastructure.
- Developed an electronics control system package that can manage signals from piezo sensors embedded into the enclosure via the phone and landline system to a central control function, improving system integrity by 20%.
- Developed a system to reduce by 100% the need to perform routine manual maintenance on emergency telephones by embedding a piezoelectric impact monitoring device into the telephone casing and reporting any telephone issues to a centralised control station where actions to resolve the problem can be instigated.
- Allowed the automatic allocation and notification of emergency telephone problems to maintenance engineers via SMS or email within a period of one hour from receiving the notification from a damaged phone.

The proposed system will have the ability to replace existing emergency systems, and be installed during new road build, providing two access paths to the market. The total market accessible by the technology is estimated at EUR 250 million per year.
