Description

The proposed utility model relates to means for measuring and recording elements of the time taken to complete technological operations during an operational and technological assessment during testing of agricultural equipment.

The device is known as “Electronic timekeeper” (Utility Model Patent. 35454, Russian Federation. IPC G07 C / 5/10 Electronic Timekeeper [Text] / Zubov N.I., Ladosha N.I., Saraev V.P .; applicant and RosNIITiM patent holder.) The device contains an electronic information storage unit, including logical recognition elements of signals that are connected in a certain way, multi-channel information storage counters, indicator board and multi-button control panel, electronic timer, primary converter and connector s for connecting sensors.

A disadvantage of the known device design is the complexity of the design, large overall dimensions, an uninformative alphanumeric display, a limited built-in set of codes for shift time elements, the inability to correct accidental keystrokes or the wrong choice of the operation to be performed, the lack of a built-in battery, which requires a test unit to be connected to the on-board network. Such characteristics of the electronic unit require a specialist, performing the timing, located in the cab of the test unit next to the machine operator. The insufficient amount of non-volatile memory does not allow recording all the characteristics of the tested unit and the background on which the tests are carried out.

The purpose of the utility model is to ensure autonomy during testing, to store in the non-volatile memory of the device all information about the unit under test and the place of the test, to increase the accuracy and visibility of the fixation of time elements of technological operations with the possibility of correcting accidental keystrokes or incorrect selection of the type of operation.

To ensure this goal, an improved design of the measuring device is proposed, which allows to process and save the timing results during tests of agricultural machinery.

Figure 1 shows the electronic timekeeper’s device, made in a dustproof case and designed to measure and record the time intervals of operations (start and end times) included in the timed production process to evaluate its performance in agricultural machinery tests. The device uses a new generation microcontroller STM32F405 based on the AWP core, which has low power consumption, high speed and a large amount of built-in permanent and random access memory. On the front panel of the device there is a button keyboard - 1 and a 4.3 '' - 2 TFT touch screen. The device is powered by a 3.7 V Li-Ion battery. A micro-USB connector is provided for charging the battery and transferring the measurement data to a computer .

Before starting the time using the virtual keyboard on the touch screen of the device, the characteristics of the unit, the names of the performers, the characteristics of the field and the farm on which the fields are tested are entered. In the timing mode, switching between current operations is done using the button keyboard. On the right side of the screen displays a hint of a possible type of operation -3. It is possible to correct the code of the current operation. The display shows the code and name of the current operation of the unit under test - 4, as well as the total time since the start of timing and the duration of the current operation - 5. In the middle part of the screen, the history of the operations performed is displayed - 6. If the current operation can last a long time, for example, “5 - rest "or" 33 - adjustment "- the device can be turned off. After switching on, the operator will be asked to continue the incomplete timing or start a new one. The entire list of operations of the current timing is stored in non-volatile memory. After the shift is completed, the generated electronic chrono-card is recorded in a special format on a removable SD memory card. All actions during operation can be performed using either the keypad or the touch screen.

The advantage of the proposed utility model is that a microcontroller having a built-in non-volatile memory that allows you to save all information about the unit under test and the place of the test for further processing on a computer, a touch screen configured to display the operation performed, the history of operations performed are introduced into the device design and tips on possible modes of operation with the ability to adjust the input data.
