    Product line proven over two decades

The Tacholink T5 is our on-board, on-line Event Data Recorder with telematics functionality.  Now in its fifth generation, and having been introduced almost two decades ago, Tacholink is a proven product line which is in widespread use around the world.  In the early 2000’s Bowmonk supplied the first generation Tacholink to Norfolk Police, and these units are still in operation to this very day.

The T5 records a wealth of high-resolution data about the vehicle and sends this to Intelligo – the T5’s web-based reporting solution.  Fleet managers or other staff login to Intelligo and are able to view live or historical data for the entire fleet, including customised reports to quickly highlight their desired information.  Intelligo can also pass the data on for integration into third party systems. 

The T5 can be used for many purposes, including:

  • Event Data Recorder (EDR)
  • Driver Behaviour Monitoring
  • Vehicle Tracking
  • Ensuring Regulatory Compliance (e.g. Health & Safety)
  • Monitoring Asset Utilisation 
  • Maintenance Alerts

The T5 is built into a high impact, chemical resistant, resin enclosure which provides sealing options up to IP68 and meets the environmental standards of J1455.  The unit is therefore protected against the harshest of anticipated environments.  The enclosure includes 4 anchor points and is self-locking, providing vibration protection and tamper resistance.

What does it do?

In a nutshell, the T5 gathers high-resolution data, records it locally, and uploads data to the Intelligo cloud-based reporting system.

What data does the T5 gather?

The T5 has a wealth of inputs and sensors which allow it to record the following information:

  • Vehicle location, using a built-in GPS receiver 
  • Heavy braking, acceleration or cornering, using a built-in 3-axis accelerometer.  This allows the T5 to detect erratic driving as well as more serious events such as vehicle impacts.  The G-force data gathered by the T5 is invaluable in building up a detailed picture of events that occur before and during an incident.  
  • Vehicle speed, via a dedicated analogue sense wire.  
  • Engine RPM, via a dedicated analogue sense wire.
  • Ignition status, via a dedicated sense wire.  By monitoring the ignition input the T5 can provide start/stop times of trips.
  • Multifunction inputs – up to 13 programmable inputs for recording virtually any type of event, such as doors opening/closing and activation of indicator or warning lights.  The T5’s inputs can capture frequency, analogue voltage or digital input emulation.
  • CAN-bus events – any CAN events which are broadcast on the network in question can be detected and recorded.  Includes support for J1939 & OBDII over CAN. 
  • RS-232 data from external systems can be captured and reported back to Intelligo (e.g. weight data from on-board weighing systems, or data from a TPMS system).
  • Driver identity – the optional Driver Interface Box records the identity of the driver through the use of tags, including log-in / log-out times.
  • Time & date, courtesy of the T5’s built-in Real Time Clock which is synchronised via GPS.

The T5 also has 4 x relay outputs which can be controlled using on-board logic.

How detailed is the data? 

The T5 differentiates itself from other telematics products on the market by reporting at very high resolutions.  Data is typically reported at 1 Hz (i.e. once per second), but during and shortly before an “incident”, where a pre-defined G-force threshold has been exceeded, the reporting rate rises to up to 25 Hz (i.e. 25 readings per second).  

This high level of detail is invaluable in reconstructing an accident – e.g. to prove that your driver was not at fault.  


What does the T5 do with the data?

The T5 records data, along with time and date stamps, in its robust and non-volatile on-board flash memory.  If a serious accident should occur and power is lost to the T5, any information that has been captured and stored up until that moment will be retained for later analysis.

Once data has been recorded it is then transmitted to Intelligo (via either Wi-Fi or 3G) in near real-time.  

Sending data via 3G is the most popular option, which involves the T5 being shipped with a built-in M2M SIM which has the option of roaming across all UK networks for optimum coverage.  EU-wide options, including multi-network roaming, are also available.  Thanks to Bowmonk’s partnership with a leading M2M data provider, data pricing is extremely low and there is no need for the customer to take out an additional contract – data costs are simply included in the Intelligo subscription charge.  

Alternatively, for customers who have on-board routers in their vehicles, or who have a depot-wide Wi-Fi network and do not need access to live data, the T5 can send data by connecting to any Wi-Fi access point.  

Although not recommended, due to the effort of capturing data, the T5 can simply record data to its on-board memory without onward transfer to Intelligo.  Data can be collected when required by connecting a USB mass storage device to the T5, and we provide a PC-based application to view this data.  The PC application can upload data to Intelligo, but not all Intelligo features will be available for manually uploaded data.  

Intelligo

Intelligo is a web-based reporting and management utility for T5 devices.  All data collected by T5 devices can be uploaded automatically to the cloud, via either Wi-Fi or 3G, and Intelligo lets you view this data - or notifies you proactively of pre-configured exception events or incidents.

Exception Reports

Exception reports allow fleet managers to be notified of pre-defined events within minutes of them happening, allowing them to take immediate action if required.  Such events could include non-use of a seatbelt, excessive speed, harsh acceleration, vehicle roll-over or entering/exiting defined locations (geo-fencing).  

Condition Based Monitoring & Maintenance

Intelligo can report any desired inputs as and when they occur.  Such inputs could include real-time monitoring of a TPMS system, oil pressure, or engine & bearing temperature. 

Configuration and Updates

As well as allowing you to view data, Intelligo is also able to remotely update the configuration of any T5 in your fleet, including updating its firmware, thereby eliminating the need for an engineer to visit each vehicle in the event that the configuration needs to be changed.

Driver Tag Reader

The optional Driver Tag Reader is a dashboard-mounted box which reads a driver’s tag, thereby identifying the driver to the T5.  Driver log-ins are date/time-stamped, enabling driving hours information to be calculated.  The dashboard box contains an LED which indicates a successful driver log-in, and a built-in buzzer which can prompt the driver to login by beeping either briefly or continuously.  In addition the buzzer can be used to notify the driver of pre-programmed exceptions – such as exceeding a maximum vehicle speed or engine RPM.  

Customisations

The T5 is a highly flexible platform that can be customised depending on customer requirements.  Features that can be developed could include:

  • Support for CAN protocols other than J1939 and OBDII over CAN
  • PWM outputs in addition to relay outputs
  • Support for two CAN channels instead of one
  • Even higher resolution of data logging
  • Own-branding of the Intelligo cloud reporting platform
  • Identify drivers using an inventory of existing RFID tags
  • Provision of real-time and detailed feedback to the driver
  • More than 13 multifunction inputs
  • Integration work to capture and report data from another on-board system (e.g. TPMS or on-board weighing).  
  • Integration with third party back-office systems (e.g. to use T5-captured data in a client’s own web application, such as a bus company showing live ETA information for each bus stop on its own website or app)
  • Removal of cellular modem (i.e. Wi-Fi only) to reduce cost

These are all features that can be implemented depending on volume.  Please contact us to discuss your requirements.
