if the output signal of the sensor does not meet the judgment condition, the current test tube is not positioned in the bar code scanning area;
and if the output signal of the sensor meets the judgment condition, the current test tube is positioned in the bar code scanning area.
In this embodiment, the controller is a PLC programmable controller. The output signal of the sensor 12 comprises an analog signal and/or a digital signal.
When the output signal of the sensor 12 is an analog signal:
presetting a judgment condition in the controller PLC, wherein the judgment condition comprises at least one of selected current, voltage, frequency, temperature and the like as an electric analog semaphore; setting the threshold range of the electric analog semaphore as a standard comparison threshold;
sending the acquired current analog signal of the sensor to a controller, and comparing the current analog signal with a standard comparison value threshold in an analog quantity comparison module:
if the current analog signal is within the standard comparison value threshold, the output signal of the sensor meets the judgment condition, the controller outputs a control signal, and the current test tube is located in the bar code scanning area;
if the current analog signal is not in the standard comparison value threshold, the output signal of the sensor does not meet the judgment condition, the controller outputs another control signal, and the current test tube is not located in the bar code scanning area. The test tube rotary disc 7 drives the current test tube to continue rotating.
When the output signal of the sensor 12 is a digital signal:
presetting a judgment condition in the controller PLC, wherein the judgment condition comprises at least one of selected current, voltage, frequency, temperature and the like as an electric digital signal quantity; setting the numerical value of the digital semaphore as a standard comparison numerical value;
sending the acquired digital signals to a controller, and carrying out numerical comparison with a standard signal preset in the controller:
if the acquired current digital signal is matched with the standard comparison numerical value, the controller outputs a control signal, the current test tube is located in the bar code scanning area, and the test tube turntable stops rotating;
if the collected current digital signal is not matched with the standard comparison numerical value, the controller outputs another control signal, the current test tube is not positioned in the bar code scanning area, and the test tube turntable continues to rotate;
