This invention relates generally to an apparatus for attachment to a vehicle located in remote sites in order to test and record test information related to the tension and load capabilities of anchors located at remote sites.
In the oil and gas industry it is often necessary to test the load or tension capabilities of a given anchor system located in remote areas and locations. Often, regulatory agencies seek to verify that the anchors used in remote areas and locations are capable and safe to use. The regulatory agencies often require a given anchor to have documented information in the form of printouts and electronic data available for regulatory inspection. The agency requirements often demand that a given anchor hold a load for a given period of time. Often a 20,000 pound test lasting two minutes in duration is required on a given anchor in the field. Thus, the operators in the field need to produce the testing information which verifies location, often longitude, latitude and elevation, as well as a known tension and time testing verification. Thus, there is a long felt need in the industry of anchor testing for an apparatus to print out and save electronic data verifying or certifying a oven anchor in a specific location.
Accordingly, it is an object of embodiments of the present invention to provide an apparatus that allows testing a load and providing verifiable printouts and electronic data certifying and/or verifying an anchor qualifies per a given regulatory or agency demand or requirement.

The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference characters refer to the same or similar elements in all figures.
The devices in communication with the programmable logic controller 1 include a pressure transducer measurement device 4, an analog to digital converter 8, a global positioning system information receiver 3, a human machine interface 2 having a screen interface portal, a memory device 6, and a printer 5. In another embodiment of the invention, the programmable logic controller includes and is in communication with a universal serial bus port 10.
The data logging program is logic embedded in the programmable logic controller 1 and the memory device 8, typically an SD memory card. The data logging program unctions to collect and to convert the various conventional data streams into programmable logic controller 1 and other device compatible data streams as well as saving and preserving data to the memory device 6. The data logging program activates the programmable logic controller 1 by a sending a create instruction embedded in the programmable logic controller logic system. The create instruction configures the data ladder logic convert block 7, which receives and stores all the data that is gathered, used, manipulated and stored during operation and sends the data to the memory device 6. The create instruction also sets up the format for the .csv file. The .csv file data is laid out to fit in a spread sheet format for access independent of testing operations. The .csv file comprises ASCII strings and numerical values in the data. The ASCII strings and numerical values arrive from the interfaces of the human machine interface 2, GPS 3, and the pressure transmitter 4, which is sent into the programmable logic controller 1 and the memory device 6 for storage.
The data may be saved when the programmed programmable logic controller instruction opens the .csv file, the operator, using the human machine interface 2, communicates with the programmable logic controller 1 to save the data collected from the various devices. After the testing is done, either the operator at the human machine interface 2 ceases collection of the test data or the operator previously activated a predetermined collection time and the programmable, logic controller 1 ceases data collection. The programmable logic controller 1 closes the .csv and the data is stored. The .csv file is transferred by programmable logic controller 1 internal communication to a memory device 6.
The programmable logic controller 1 is in communication with the GPS 3 as data is communicated and confirmed via ASCII and numerical communication between the two devices 3A. The GPS information contains latitude, longitude and elevation information and is transferred to the programmable logic controller ire an ASCII string format. The programmable logic controller 1 verifies the length of the ASCII string due to multiple data strings 3A from the GPS 3. The correct data is received once every second. The ASCII string is moved into a buffer if the correct length is verified by programmable logic controller 1. The programmable logic controller 1 separates the latitude, longitude, and elevation from the string after it verifies the correct character in the 17th (numeric) position in the ASCII string. The programmable logic controller 1 uses a ladder logic “Equal To” instruction for the 17th position verification. The latitude, longitude, and elevation data 2A is communicated from the programmable logic controller 1 to the human machine interface 2, data logging program, and printer.
The global positioning system information receiver receives location and elevation information and sends data to the human machine interface via the programmable logic controller is display only format. The data logging program stores the global positioning system information receiver data with each test to be recalled later. The printer requires that the global positioning system information receiver data sent to the programmable logic controller 1 then to the printer 5 to be converted to hex byte communication format 5A so that the printer 5 can read the data. The programmable logic controller 1 changes ASCII to characters then to hex byte format with the use of the ladder logic convert blocks 7. The hex byte communication format 5A is then converted back to ASCII format by the printer internal software. Typical printers used are Zebra™ brand kiosk-style printers.
The human machine interface 2 generates information data in ASCII and numerical value format and communicates this information to and from the programmable logic controller 1 in a profinet packet format 2A. The profinet packet format communication 2A is manipulated by the data logging program of the programmable logic controller 1 and sent to the ladder logic convert block, memory device 6 and printer 5. The data logging program of the programmable logic controller 1 stores the human machine interface data with each test in the programmable logic controller 1 and the memory device 6 to be recalled later.
The printer 5 requires that the human machine interface data exist in a hex byte format that the printer 5 can read. Thus, the programmable logic controller 1 converts the human machine interface ASCII data format and integer data (numerical value) into characters and then into hex byte format with the use of the ladder logic convert blocks 7. The programmable logic controller 1 communicates the information via hex byte format 5A between the programmable logic controller 1 and the printer 5.
During anchor testing measurements, the pressure transducer measurement device 4 produces and communicates a raw analog signal value 4A that is sent to the programmable lope controller 1 and then transferred to the analog to digital converter 8. In the analog to digital converter 8, the communicated raw analog signal value 4A from the pressure transducer measurement device 4 is converted to a “NORM X” integer value format, then to real scaled digital value and then into a double integer value. The real value is used in “Scale X” to set the high & low value to a double integer. The double integer represents pounds of force from the pressure test measurement as obtained for the pressure transducer measurement device 4. The analog to digital converter double integer value is communicated 8A to the programmable logic controller 1 and ladder logic convert block 7. The data logging program stores the pressure transmitter data with each test in both the programmable logic controller 1 the memory device 6 to be recalled later.
The printer 5 requires that the pressure transmitter data be communicated in the hex byte format 5A for the printer to read. Thus, the programmable logic controller 1 changes ASCII and integer data to characters then to hex bytes with the use of the ladder logic convert block 7 in communication 5A between the programmable logic controller 1 and the printer 5.
The programmable logic controller 1 is in communication with the universal serial bus port 10. The programmable logic controller 1 and the universal serial bus port 10 communication 10A is typically in a .csv format or ASCII format. The universal serial bus port 10 allows for information be transferred to a computer or to a device to provide for remote or off site testing control.
The programmable logic controller internal clock 9 sends clock data time information communication 9A to the ladder logic convert block 7 of the programmable logic controller 1, which sends the time information to the human machine interface 2 for user review on the screen interface portal, not depicted. The human machine interface 2 sends that information back to the programmable logic controller 1 and ladder logic convert block 7 with communication information input into the human machine interface 1 by the user. Additionally, the data logging program stores the clock data with each test. Information from the programmable logic controller and the ladder logic convert block to and from a memory device in communication 6A and is typically in a .csv file format.
The printer 5 requires that the clock data be communicated in a format 9A that the printer can read. Thus, the programmable logic controller 1 changes ASCII and integer data communication 9A from the internal clock 9 to characters then to hex bytes with the use of the ladder logic convert blocks.
