The invention relates to quality control of products of animate and inanimate nature and can be used to assess the safety of food and feed products, natural and waste waters, soils, soils, development of MPC pollutants, and the impact of human activities on the environment, including food production and refining of oil.

A device for determining the quality of the products of animate and inanimate nature. It consists of computer software and biodetector, including a controller moving the Ouija Board with containers (in the form of a truncated cone) for the test object, the light source (led, microscope with microphotography device and the camera, which by the video image capture communicated with the corresponding computer input (RF patent No. 2346031, 2009).

The disadvantage of this device is that as the optical system used binocular stereoscopic microscope (MBS) and microphotography device (MFD). In this optical system, a light signal first enters the lens of the microscope, and then through a system of prisms is rotated 90 degrees and enters the camera. Thus, the transmitted image is quite a long way and is undergoing significant to icesto optical transformations, that distorts the image. In the result, the aperture ratio decreases, which affects the accuracy of the calculation of test objects, the speed and accuracy of measurement and the sensitivity of the device. Capacity with the test objects are not isolated from the external environment, and therefore occur in the process of measurement light interference degrade the image quality. The lens of the microscope above the tanks is carried out by rotating the optical system of the microscope and settings over capacity with the test objects, which is rather time-consuming procedure, which does not ensure the desired accuracy of fixation. The use of a single led does not provide the necessary uniformity and illumination of the test object, which significantly reduces the speed of the count.

The technical objective of the claimed invention is to provide such a device that would provide an objective definition of the object.

The technical result is to expand the functionality of the device, reducing its size, simplified design, improved accuracy and expressnet measurements.

The problem is solved by a device for determining the quality of the products of animate and inanimate nature, consisting of computer software and biodetector, comprising a housing, inside which finds the I controller move planchettes with containers for the test object, each of which is made in the form of a truncated cone, the light source is led, located below the measured capacity for the test object, the optical system with a camera mounted on a tripod with a video image capture message with the corresponding input of the computer, the device is equipped with additional LEDs mounted under the Ouija Board reed contact for strict fixation capacity for test objects under the hole in the Ouija Board, a light-tight casing for closing the top of the planchettes with containers for the test object, the inner surface of which is covered with white Matt paint, and the casing has a hole whose diameter corresponds to the diameter tanks for the test object, and the LEDs are located opposite to each other, and camera lens made with the possibility of its installation as close as possible to the measured capacitance with the test object directly above it.

Optical system with camera strengthened by the rotary mechanism, in the form of a ball head on the tripod.

The device shown in figure 1, a side view, figure 2 - front view.

The device consists of a computer with software (not shown) and biodetector, comprising: a housing 1, which is located inside the controller move planchette with containers 3 to the test object; the light source - LEDs 4; an optical system with a television camera 5 and the lens 6 mounted on the tripod 7. In addition, the device is additionally equipped with a light-tight casing 8.

Optical system with camera 5 and the lens 6 is strengthened by the turning mechanism 9, in the form of a ball head on the tripod 7. Inside the housing 1 is a stepper motor 10 for rotating the Ouija Board with 2 tanks 3.

To simplify the design of the proposed device, improve accuracy and expressnet measurements were made amendments into the optical system, the locking mechanism and adjustment planchettes with containers, as well as in the lighting system.

As the optical system instead of a binocular microscope and microphotography device is a camera lens. This design allows you to set the camera 5 measured directly above the tank 3 with the test objects as close as possible to it. In the length of the light beam from the wells with the ciliates to the camera is reduced from 320 mm to 56 mm, i.e. almost 6 times. Due to this reduced light loss and, accordingly, increases the brightness of the image provided by the optical system. In addition, the increase in light output is also achieved by reducing the reflection at the boundary poverhnostyah-glass in MBS and IFIs, and also due to the reduction in the number of interfaces used in the optical system.

The Ouija Board with 2 tanks 3 closed top black opaque metal casing 8 with a hole on the measured capacitance. The cover 8 prevents the ingress of external light at the time of calculation of test objects and, thus, ensures the stability of the lighting capacity 3. In addition, the inner surface of the casing 8 is covered with a white Matt paint, and therefore, the reflection increases the overall illumination of the vessel 3, and therefore, the accuracy and speed of calculation.

Changing the position of the camera 5 is achieved due to its rotation (90 degrees) with the help of a special mechanism 9 hard ball fixation (ball head), which provides a slight bias and precision installation of cameras 5 over capacity 3 with the test objects.

As the light source used two LEDs 4, located opposite with respect to each other. This design provides uniform illumination capacity 3, including its lateral surface. On this surface due to its high light focus test organisms due to positive phototaxis. So all they will be well counted with minimal error.

The computer includes a video image capture, the conversions the total analog signal in digital cameras. The digitized signal is recorded using a specially designed program in the RAM of the computer and is transmitted as an image on the monitor. This program controls the electronic circuit of the controller of the stepper motor.

The operation of the device begins to activate the switch network filter. This enables the camera and light up two LEDs to provide uniform illumination of the wells with test objects.

Software package performs automatic assessment of the degree of toxicity of the investigational product by comparing the amount of moving test objects (ciliates) before and after exposure of the investigated substances. For a complete cycle of operation, the program counts the number of ciliates in the hole twice: before making the solution of the extract and after making. Then, it calculates the degree of toxicity of each sample.

The control software system STELON.EXE provides:

- easy configuration of the system equipment;

- determination of the degree of toxicity of one or more samples in a given number of holes;

- write intermediate results to disk and reading them from disk.

- editing and printing of results.

The next phase of work begins with making use of the dispenser in every capacity 3 planchettes 2 suspension of ciliates in the amount of 100 µl. After performing this operation, p is assetco 2 set on the table stepper motor 10, closed light-tight casing 8 with hole and using the ball head 9 on this hole sets the camera 5 lens 6. The ball head 9 provides for changing the position of the camera 5 (rotate 90 degrees) and its precision installation above the tank 3. Strict fixation capacity under the hole provides the reed contact located under the Ouija Board 2.

The investigated product is determined by the relative difference (in %) between the first and second calculation on the basis of the obtained results is assessed by the degree of toxicity (safety) at an appropriate scale in relation to each of the tested product.
