Data Logger

(45 KB)  (click to enlarge)

   The TANDC-20 Data Logger is simple to install and operate. The unit mounts in the cab of the vehicle, and connects to the oil sensor, odometer and key switch. Each time the engine is started or stopped, or when the key is turned on or off, the unit records the time and date of that event. Miles driven are also continuously recorded, so that each time the vehicle passes by the gate collection box, the total miles driven, engine hours and key on times can be logged back to the central computer. The TANDC-20 needs to be connected to the vehicle's battery to be continuously powered, but draws very little current so it will not drain the battery when the vehicle is not running. Expandability is built into the unit, and it can be configured to record other data such as the amount of material delivered by a salt spreader. Operator information such as job codes can also be entered and time stamped by means of a user friendly interface of only 6 buttons. Up to 30,000 events can be recorded between transfers to the gate collection box.

Each time a vehicle passes near the Gate Collection Box, data stored in the TANDC-20 Data Logger is transmitted via an RF (Radio Frequency) transmitter to the Gate Collection Box. Updates and any new information for the vehicle can also be transmitted from the the Gate Collection Box to the TANDC-20 Data Logger via the same RF connection. The driver simply passes by the Gate Collection Box and colored lights mounted near the Gate Collection Box will indicate a transmission is in progress and the  driver needs to pause momentarily. A different colored light will inform to the driver that all data has been successfully exchanged and it is O.K. to continue on. In normal operation the driver would pass by the Gate Box when leaving and returning to the yard, thereby providing before, during, and after time stamped data. Information collected from different vehicles is temporarily stored in the Gate Box before being sent to the office computer for processing and display. The Gate Box can be easily customized to accommodate a wide variety of different yard configurations. Depending on location and placement of the Gate Collection Box, it can be powered from a solar cell array with a back up battery, or it can be line powered. Data can be sent to the office computer using RF modems for remote installations, or hard wired where possible.

The office computer is a standard IBM PC. It communicates with the Gate Collection Box using RF modems or through a hard wired connection, depending on installation.  The software can be installed on an existing computer if desired, as long as the computer has 1 free serial port available. The office computer and software collects all the data from the individual vehicles, and displays maintenance information in an easy to read form. If desired,  this information can be exported as text and used by a wide variety of other programs such as Excel, Word, Access, etc. as well as by most existing maintenance programs in use today. We can also tailor the software to fit your individual needs. Contact Safety Technologies for further information.

Remotely Driven Vehicle

We would like to introduce you to the RDV - Remote Driven Vehicle. The most technically advanced, heavy vehicle control system in the world. Even though highly sophisticated, it is surprisingly easy to operate. When the system is turned off, it remains silent, allowing the truck to drive and handle normally. The modular component design eliminates costly diagnostic time by allowing maintenance personnel to simply 'plug and play'.

System Overview

   Four computers, two in the truck and two in the remote controller, monitor all vehicle functions, carry out all commands, and govern communications protocols. The second and fourth computer provide double redundancy to assure absolute safety, and a logical and orderly shutdown in the unlikely event one should fail.
    To assure absolutely secure data transmission between the truck and the remote controller, we are using 2.4 Ghz. spread spectrum modems. This former military communication technology provides a safe and secure communication link.

Control Hardware

   The steering is controlled by a servo motor whose response rates can be adjusted to suit individual operator preferences. The steering self centers, and the throttle reverts to idle any time the operator releases the respective joy-stick.
    The service brakes are controlled by an electronic proportional air valve. The response rate is mapped to the joy-stick bit position and, as a result, the operator can feather the brakes just as if they were in the cab with their foot on the pedal.
    All binary control functions are carried out through the use of extremely reliable solid state relays. We even go the extra distance and spec gold plated plugs and sockets, and EMI shielded cables.

PCM (Portable Control Module)

   In addition to being a heavy duty industrial enclosure with a shoulder harness, it has the following features;

• Alpha-numeric LCD display provides the operator with a constant status report of the vehicles primary functions. In addition, it explains the reason and corrective action to be taken if a constraint scenario is activated. Additionally, the speed in mph is continually displayed.

• Rechargeable hard shell battery pack.

• Two 'Touch To Operate' bars, assure that the operator must have one or both hands on the PCM.

• If the operator falls down, the built in tilt sensor will stop the vehicle immediately.

• Membrane keypad to prevent moisture ingress.

• Additionally the PCM controls the following items:

          Headlights - Turn Signals - Emergency Flashers - Air Horn - Gear Shifting

Emergency Stop - Engine Starting - Steering - Accelerating - Braking

TCM (Truck Control Module)

    This very compact, steel enclosure is mounted between the operator and passenger seats. Note the following features;

• Battery charger with a conditioning cycle.

• 360° G-Force sensor.

• DB-9, RS-232 diagnostic port.

• User interface key pad.

Additional Features

• Every time the transmission is shifted into neutral the emergency brakes automatically engage.

• When the truck is shifted into gear the turn signals oscillate, thereby giving the operator visual feedback as to the transmission status.

• The system allows a user defined fast engine idle condition, to prevent battery depletion due to auxiliary lighting.

• 36" touch strips mounted on each fender allow other workers to stop the truck if they deem necessary.

• The collision avoidance system senses the presence of objects and stops the truck.

• The communication is continually being monitored, and when a drop is detected the truck is stopped, and cannot be operated until re-established. When a drop is detected the headlights will flash for a maximum time of 30 seconds.
