After installation of the system, it is calibrated by Nucleonix Engineer by generating Profiles for trucks of various Models, Makes, Lengths and Heights. The data related to trucks are stored in a Calibration file. For every acquisition, TMS Software shows the available calibrated Truck profiles & asks the User to select the Truck profile. This data is used in reports to arrive at a logical conclusion on Contamination. Details are given in Appendix A. Re-Calibration is required every 1 year.
MAKING CONNECTIONS AND IDENTIFYING COM PORT:
Make the hardware connections as per the Hardware user manual. Connect the Serial cable from TMS Electronic Unit to PC COM port. In case PC does not have a COM port, connect it to USB-Serial convertor. USB-Serial convertor acts as an equivalent of COM port. The drivers for USB-Serial convertor must be installed before it can be used.
After making connections, the COM port number must be identified. For this, Right click on ‘My computer’ icon on Desktop. Select Properties -> Device Manager -> Ports. You will find the COM port number. For eg. If you find ‘COM3’, it means that COM port number is 3.
EXECUTING THE APPLICATION:
Click on Start -> Programs –> Nucleonix Systems -> TMS or Double click TMS icon on Desktop to run the application. A login window appears as below.
This appears as COM port number is not yet set. Click on Ok button.
Setting the COM Port
Now select Config menu and click on ‘Set COM port’. In the window that pops up, enter the COM port number and click Ok. The application is terminated for the new settings to take effect. Now ReRun the application.
Let us now explore the other options in Config menu.
Setting the Counting Time
Clicking on ‘Counting Time’ will open a window, where we can set the counting time per reading. It is set to 1000 mSec by default. It is found to be optimum for Truck/Container monitoring application and need not be changed.
Setting IR Sensor Mode
The system has 2 sets of IR sensors that detect the vehicle presence and Start / Stop the Acquisition automatically. The IR sensors are physically placed right next to the detector frame on both sides. They are mounted at a suitable height in such a way that they do not see any gaps in trucks. Acquisition starts when both IR sensors detect the presence of a vehicle, that is, when front part of vehicle fully covers the detector width. The acquisition stops again when rear of the vehicle passes the first IR sensor.
By default, IR Sensor Mode is set to ‘Auto’ meaning that vehicle is detected automatically.
In certain cases, trucks have gaps between driver’s compartment and container. In such cases, ‘Auto’ mode will not work. In such cases, ‘Manual – Button’ mode must be selected. In this case, acquisition must be manually started using ‘Acquire Truck Data’ and stopped using ‘Stop Truck Data Acq’ buttons.
Vehicle Profile Selection
Vehicle profile can be selected from available profiles in Calibration file. 2 modes are available – Auto & Manual. Selecting ‘Manual’ mode will prompt the User to select Truck profile just after acquisition. The selected Truck profile will be the basis for detection of contamination.In certain cases where unmanned operation is required, ‘Auto’ mode can be selected. In this case, we fix the Truck profile to a certain make & model that is the closest match to the vehicle being scanned in terms of dimensions and shape. However, this will not be as accurate as ‘Manual’ mode.
Turning the Alarm on Panel ON/OFF
Alarm indications on Panel can be turned OFF if required. In such cases, indication is provided only on software screen.
Click on Acquire -> Start to start the acquisition of Background data. The screen will look like below.
Notice that there are 2 Graphical windows – one on top is for plotting the Background (BG) spectra and the other for plotting data from Truck. The data from various detectors are indicated in different colours and Sum data is indicated in pink. On top, ‘System health’ grid is shown. There is an indicator – RED / GREEN corresponding to each major component of the system. Failure of any of them turns the corresponding cell RED. System Health checks are performed during IDLE mode. The cells indicate the statuses of:
SBC – Single Board Computer, LV1 & LV2 – Low Voltage supply 1&2, IR1 & IR2 - IR Sensor status 1&2, Dx_Stat – Detector Status – Working or failed, Dx_HV – Detector HV status, Dx_Alrm – Detector Alarm status.
Apart from this, on the right, there is a Grid that shows average background data. There is another grid on bottom right that shows Truck data like Vehicle direction, whether vehicle is detected or not, Acquisition mode, Time out state and vehicle speed.
The system will be ready to acquire the Truck data once it generates 200 data points for Background.
The indication on Truck Monitoring System Electronic Unit (Panel) turns to GREEN and it reads “INSTRUMENT READY TO SCAN VEHICLE”.
Checking Contamination in Trucks
Acquisition of Truck data will start & stop automatically in ‘AUTO’ IR Sensor Mode, as soon as vehicle crosses both the IR sensors. In manual mode, “Acquire Truck Data” button must be pressed to start and “Stop Truck Data acq” to stop acquisition.
Notice the spectra in 2nd Graphical window that corresponds to Truck data.
The Truck must be allowed to pass between the detectors as slowly as practically possible with a maximum speed less than 2 Km/hr (0.5m/s). Vehicle speed is reported in the bottom right Grid as well as in the report. The slower the truck speed, the better are the chances of detecting radioactive contamination.Once the acquisition is completed, analysis of data is performed based on the selected Truck profile and report is generated.
In cases of Contamination, Audio and Visual alarms are generated on Panel & software. The Panel LCD turns RED with “Vehicle Contaminated” message. The below message appears on PC. Once the User acknowledges, report is shown on the screen. It will be named as “Latest Report_Date_Time” by default and can be renamed & saved as required. The system will be ready to scan the next truck.
Clicking on Report Menu will show up previously saved reports. They can be selected for viewing, editing & printing.
Interpretation of Reports
Given below is a sample report for a truck carrying steel scrap which is contaminated.
Notice the Alarm Status row, which shows that data from detectors D1, D2, D3, D4, ‘Avg of all detectors’, ‘Sum of all detectors’ - is contaminated.
Notice the % Fall row, which shows that there is an increase of 3.75% in average readings from all detectors for this truck. This again implies that there is contamination. Now notice the Spectrum data Section - ‘Sum’ column. There are several continuous readings which have crossed statistical limits of 3 Sigma (indicated in RED), which again suggests Contamination. Look at the Statistical Observations section. The Sum row shows that ‘Total Events Score’ and ‘Events in Sequence Score’ are both high, which indicates contamination. (Event is the case when current data value exceeded Sigma or 2 Sigma or 3 Sigma.
Let us now analyze another report shown below, which has much lower contamination:
Notice the Alarm Status row, which shows that data from detectors D1, D2, D3, D4, ‘Avg of all detectors’, ‘Sum of all detectors’ - is contaminated. Notice the % Fall row, which shows that there is an increase of 1.45% in average readings from all detectors for this truck. This again implies that there is contamination. Now notice the Spectrum data Section - ‘Sum’ column. There are 4 continuous readings which have crossed statistical limits of Sigma (indicated in GREEN) & 2 Sigma (ORANGE), which again suggests Contamination. Look at the Statistical Observations section. The Sum row shows that ‘Total Events Score’ and ‘Events in Sequence Score’ are both high, which indicates contamination. (Event is the case when current data value exceeded Sigma or 2 Sigma or 3 Sigma).
Clicking on this command this file is opened. In case there are any upgrades to the software, ask Nucleonix for the latest version of ‘TMS Software User manual’. Copy it to the same folder as TMS application.
Maintenance and Customer Support
Periodic functional checks of system must be performed with Check source as frequently as possible, as per procedure given in Appendix B. This can be done by Customer’s trained employees. Apart from this, PC must be kept free from Virus and backed up by UPS power.
Calibration must be performed every 1 year. You may contact us 1 month prior to completion of 1 year. Customer must enter into Annual Maintenance Contract after Warranty. This will entitle them for preventive maintenance checks, software upgrades, Re-Calibration, etc.
