CableGuardian has been designed and tested to ensure the highest level of reliability, availability and maintainability.
The CableGuardian system has been designed to be resilient to temporary loss of service of the sensor units for example due to a loss of cellular communications. If a unit or units drop out for any reason the analytics package automatically reacts and continues to operate as normal. If the unit or units comes back online the system reverts to its original configuration.
In the unlikely event that a unit needs to be replaced, all Viper needs to have sent by the installer is the serial number of the unit. The analytics will then be updated with the new unit details.
Cable Guardian has been designed and tested to meet Network Rail’s rigorous requirements for environmental testing to ensure the highest reliability, availability and maintainability. The CableGuardian unit is rated to IP65 and is Class II certified hence it is suitable for housing inside any convenient trackside locations. Qualification units have been subjected to an arduous test regime and extensive production testing of the units is also carried out.
CLOUD BASED DATA
By hosting the CableGuardian data in the cloud the potential for any single server failure to delete integrity information is removed entirely. Cloud hosting is the best possible method of ensuring data is never lost due to failure in the storage system.
HOW SECURE IS MY DATA?
The CableGuardian units use industry standard security defences and communicates to the central server using an encrypted link which includes authentication mechanisms. Users log into the CableGuardian portal using a username and password and the CableGuardian portal content is delivered to the user utilising the Transport Layer Security (TLS) protocol through a range of different web browser types. CableGuardian employs defined user access roles and permissions throughout the system.
Each CableGuardian unit transmits its data, via secure internet connection, to the remotely Cloud hosted CableGuardian Data Storage and Analytics System using one of the following communications interfaces provided:
- 4G/3G/2G Cellular (SIM embedded)
- Ethernet 10/100 Base-Tx
- Fibre Optic 100Base-FX, LC Duplex 1300nm Multimode
For system integrators, having multiple communication methods as standard offers the potential to use more than one communication method to provide communications resilience.
The SIM card provided wihin the CableGuardian unit is mobile network agnostic. The SIM automatically connects to the mobile network with the strongest signal. If there is a problem with that network the SIM will automatically switch to the next strongest provider signal. CableGuardian is therefore resilient to an outage of any one mobile operator network.
The CableGuardian service includes cloud hosting of the data returned from the CableGuardian units, cellular data provision, data analytics/management and remote email and telephone technical support to ensure availability of the system information via the Web Portal.
Viper manage software updates to the units using a secure “over-the-air” data link. No trackside intervention is required. Periodic updates to the cloud-hosted CableGuardian web portal are provided as part of the ongoing support. Customer feedback suggestions for web portal improvements are welcomed.
