Referring to fig. 3 in particular, fig. 3 is a schematic flow chart of an embodiment of the reaction tray 100 provided in this embodiment.

S10: controlling the driving device to drive the disc body 1 to accelerate from rest to a set speed, and rotating the disc body 1 by n cup positions;

in particular, in this embodiment, in order to achieve higher rotational speeds and throughput, the disk 1 needs to rotate at a higher speed as a carrier for the cuvette assembly 2; the driving device comprises a stepping motor, the stepping motor is used for driving the reaction disc 100 to rotate, the rotation speed of the stepping motor is controlled and adjusted in the process of driving the disc body 1, the disc body 1 is driven to accelerate to a set speed from rest, and the characteristic of the stepping motor can enable the disc body 1 to accelerate to the set speed from rest, the disc body 1 rotates n cup positions, and at the moment, the acquisition module 3 does not acquire optical data.

S20: controlling the driving device to drive the disc body 1 to rotate at a set speed, enabling the disc body 1 to rotate m cup positions, and simultaneously controlling the acquisition module 3 to start acquiring optical data from n +1 cup positions to n + m cup positions and then stop acquiring;

in a signal acquisition cycle, the optical data of m cuvettes 21 need to be sampled in sequence, so that the drive device is controlled to drive the disc body 1 to run at a constant speed at a set speed, the disc body 1 is made to rotate m cup positions again, and the acquisition module 3 is controlled to start acquiring the optical data from n +1 cup positions to n + m cup positions and then stop acquiring; in this embodiment, it is known that two adjacent cuvettes 21 are arranged at a distance of one cup position, so that when the tray body 1 starts to rotate, the cuvette 21 corresponding to the collection module 3 is marked with 0 cup position, and thereafter when the tray body 1 rotates, the positions of the collection module 3 relative to the cuvettes 21 are sequentially and naturally increased.

In this embodiment, the tray body 1 is accelerated from a standstill to a set speed, and the tray body 1 rotates n cup positions, because when the tray body 1 is at a standstill and is ready to rotate, the cuvette 21 corresponding to the collection module 3 is marked as 0 cup position at this time, which is equivalent to that the tray body 1 rotates n cuvettes 21 corresponding to the collection module 3 at this time, and then the collection module 3 is controlled to start collecting optical data from n +1 cup positions to n + m cup positions and then stop collecting, that is, when the S20 step is ready to be performed, the nth cuvette 21 corresponds to the collection module 3 and is marked as n cup positions, which is equivalent to 0 cup position in the S10 step, at this time, collection of optical data is not performed, and collection is stopped after collecting optical data from n +1 cup positions to n + m cup positions and at this time, m-1 cup positions pass, therefore, the optical data sampling of the m cuvettes 21 is completed, so that the states of the cuvettes 21 passing through the acquisition module 3 in the signal acquisition period are consistent, the data accuracy is improved, the consistency of the acquired data is ensured, and the extra layout is not needed.

S30: controlling the driving device to drive the disc body 1 to be decelerated from a set speed to be static, and enabling the disc body 1 to rotate n cup positions again;

like step S20, in the process of analyzing the sample, it is necessary to cycle a plurality of signal acquisition cycles to acquire a plurality of sets of data, and it is necessary to decelerate the tray body 1 from the set speed to a stop, and at this time, the optical data is not acquired; in order to ensure the consistency of the signal acquisition period, the driving device is controlled to drive the disk body 1 to be decelerated from a set speed to be static, and the disk body 1 rotates the n cup bodies again.

S40: controlling the driving device to drive the disc body 1 to reversely rotate for 2n cup positions and then stopping;

in terms of the flow of the reaction of the biochemical analysis, a plurality of signal acquisition cycles need to be repeated, after the disk body 1 is decelerated to a stop, in the whole test process, the disk body 1 rotates by 2n + m cup positions relative to the acquisition module 3, and then the drive device is controlled to drive the disk body 1 to rotate reversely by 2n cup positions, at this time, in step S10, the cuvette 21 corresponding to the acquisition module 3 returns to the position corresponding to the acquisition module 3 when the disk body 1 is about to move, so that the acquisition of optical data of the next cycle is facilitated; therefore, the consistency of the test is ensured, and the normal operation of the subsequent optical data acquisition is facilitated.

In order to ensure the smoothness of the whole rotation process when the disk body 1 is rotating and the disk body 1 is accelerated from a stationary state to a set speed, the step S20 includes:

s21: controlling the acceleration of the driving device to increase, and then reducing the acceleration until the speed of the disc body 1 reaches a set speed;

in this embodiment, the cuvette assembly 2 is installed on the periphery of the reaction tray 100, and in the reaction process of biochemical analysis, the cuvette 21 is used as a reaction carrier to sequentially execute actions such as reagent adding, sample adding, stirring, and cleaning, in order to ensure that each cuvette 21 can smoothly and stably rotate with the tray body 1, the tray body 1 needs to be started at a lower speed, the stepper motor drives the tray body 1 to gradually increase the acceleration and then gradually decrease the acceleration until the speed of the tray body 1 reaches a set speed, and the tray body 1 is gradually increased and then gradually decreased at the acceleration, so that the whole process of accelerating the tray body 1 from a stop state to the set speed is stable.

In addition, due to the characteristics of the stepping motor, according to the motion characteristics of the reaction disk 100 in the present invention, when the stepping motor is operated, as the rotation speed of the output shaft of the stepping motor increases, the torque also decreases as the rotation speed increases, and the larger the torque, the faster the change of the rotation speed of the output shaft of the stepping motor is, that is, when the disk body 1 accelerates to the set speed in a still static state and starts at a smaller speed, at this time, the speed of the stepping motor is smaller, the torque is larger, the faster the change of the rotation speed of the output shaft of the stepping motor is, the acceleration of the disk body 1 gradually increases, and then as the speed increases, the torque also decreases as the rotation speed increases, and the acceleration of the disk body 1 gradually decreases to zero, so that the disk body 1 reaches the set speed.

Similarly, in order to ensure the smoothness of the whole signal acquisition cycle, the step S30 further includes:

s31: controlling the acceleration of the driving device to be reduced and then increased until the disc body 1 stops;

when the disk body 1 is reduced to stop from the set speed, the stepping motor drives the disk body 1 to gradually increase to the speed of the disk body 1 after the acceleration is gradually reduced to reach the set speed, and the whole process that the disk body 1 is decelerated to stop from the set speed is stable by gradually reducing the acceleration of the disk body 1 and gradually increasing the acceleration of the disk body 1.

According to the characteristics of the stepping motor, when the disc body 1 is at the set speed, as the speed is equal to the maximum speed in the whole speed of the disc body 1, the moment is small, the acceleration of the rotating speed at the output end of the stepping motor is gradually reduced and then gradually increased, the speed of the rotating disc is gradually reduced when the rotating disc is close to stop, the rotating disc body 1 is rotated to be stably stopped from the set speed, and the whole process is stable without overshoot.

It should be noted that, the present application does not limit the driving device in which the tray body 1 is accelerated to the set speed in a certain regular manner in the stop state and then is decelerated to the stop state by the set speed in a certain regular acceleration, as long as the driving device can make the whole acceleration and deceleration process stable without overshoot.

Further, in this embodiment, in order to simplify the driving of the stepping motor, the step S30 further includes:

s32: the time taken for the acceleration of the driving device to increase and then decrease until the speed of the tray body 1 reaches the set speed is the same as the time taken for the acceleration of the driving device to decrease and then increase until the tray body 1 stops.

In order to facilitate the control of the stepping motor, in this embodiment, the tray body 1 rotates from stop accelerating to a set speed, and then rotates from the set speed to stop, the initial speeds of the tray body 1 in the two steps are the same, the cup positions passing through are the same, and the time consumed by reducing the speed of the tray body 1 to reach the set speed is set to be the same as the acceleration of the driving device, and then the time consumed by reducing the speed of the tray body 1 to reach the set speed is set to be the same as the time consumed by stopping the tray body 1, so that the acceleration rule of the tray body 1 from stop accelerating to the set speed is adapted to the speed of the tray body 1 from decelerating to stop at the set speed, and it can be obtained that the speed-time curve graph of the tray body 1 from stop accelerating to the set speed and the speed-time curve graph of the tray body 1 from deceleration to stop at the set speed are axisymmetric; therefore, the stepping motor is more convenient to control, the speed regulation rule is realized, and the service life of the stepping motor is prolonged.

In this embodiment, the driving device includes a stepping motor and a transmission mechanism connecting the stepping motor and the tray body 1, after the tray body 1 is decelerated from a set speed to a stop, the stepping motor needs to be controlled to drive the tray body 1 to rotate reversely for 2n cup positions and then stop, so that the cuvette 21 corresponding to the collection module 3 returns to the position corresponding to the collection module 3 again when the tray body 1 is about to move in step S10; in consideration of the mechanical characteristics of the transmission assembly connected to the stepper motor, before step S40, the method further includes:

s33: and controlling the stepping motor to stop and stop for 0.05S-0.3S.

It should be noted that, the transmission assembly connected to the stepping motor is not limited herein, in this embodiment, the transmission assembly is configured as a driving gear set and/or a belt pulley mechanism, when the driving motor rotates reversely, due to the mechanical structure characteristics of the transmission assembly, when the tray body 1 stops, the driving gear set and the belt pulley assembly still have a tendency of maintaining the original motion state, and the meshing between the gears and the tension of the belt, so that the stepping motor needs to be stopped and stopped for 0.05S to 0.3S, so as to buffer the time of 0.05S to 0.3S of the transmission mechanism and ensure the stability of the transmission assembly; and then driving the stepping motor to rotate reversely, and stopping after reversing the disk body 1 for 2n cup positions, so that the cuvette 21 corresponding to the acquisition module 3 in the step S10 is returned to the position corresponding to the acquisition module 3 when the disk body 1 is about to move, the whole process is stable and smooth, the abrasion to the transmission mechanism is reduced, and the service life is prolonged.

It should be noted that, the time for controlling the stepping motor to stop for 0.05S to 0.3S is obtained through repeated tests and researches by the inventor, and it is known that under the condition that the duration requirement of the signal acquisition period is met, the shorter the time for stopping the stepping motor is, the better the time for stopping the stepping motor is, and sufficient time buffering needs to be given to the transmission assembly, so that in the operation of the signal acquisition period, the time for stopping the stepping motor is 0.1S, the time consumed by the signal acquisition period is saved, and the efficiency is improved.

In the process of biochemical analysis, it is generally necessary to perform a plurality of signal acquisition cycles, and therefore, the step S10 is preceded by:

s01: and cleaning the cuvette 21, and repeating the steps of the first set value of the signal acquisition period.

Before optical data collection is performed, the cuvette assembly 2 is stopped at this time, so that a cleaning mechanism is used for cleaning each cuvette 21, interference between residual substances in each cuvette 21 and a sample to be detected is avoided, accuracy of optical data sampling is guaranteed, the step of a signal collection cycle of a first set numerical value is repeated on the tray body 1 after cleaning is completed, that is, after the tray body 1 is accelerated to a set speed, the set speed is maintained, optical data of m required cup positions are collected, the tray body 1 is decelerated to stop, the tray body 1 is driven to accelerate to the set numerical value, the set speed is maintained, the m optical data are collected, and the like, and the optical data of the first set numerical value of the number are completed in this cycle.

Further, for one of the cuvettes 21, after the step S01, the method further includes:

s02: adding a first reagent into the cuvette 21, and repeating the step of setting a second number of signal acquisition cycles;

adding samples into the cuvette 21, and repeating the step of setting a third number of signal acquisition cycles;

stirring the first reagent and the sample in the cuvette 21 for the first time, and repeating the step of setting a fourth number of signal acquisition cycles;

and adding a second reagent into the cuvette 21, and repeating the step of setting a fifth number of signal acquisition cycles.

And stirring the first reagent, the second reagent and the sample in the cuvette 21, and repeating the step of setting each signal acquisition cycle of the numerical values in the sixth step.

For one such cuvette 21, the reaction scheme in the cuvette 21 is typically: washing, adding a sample, adding a reagent, and stirring, wherein the number of times of adding a reagent or a sample in the cuvette 21 is not limited, and is specifically determined according to the sample and the type of the reagent or the optical data to be collected by the collection module 3, in this embodiment, the reaction in one cuvette 21 is to wash the cuvette 21, add a first reagent to the cuvette 21, stir the first reagent and the sample in the cuvette 21 for the first time, add a second reagent to the cuvette 21, and stir the first reagent, the second reagent and the sample in the cuvette 21 for the last time, and each step in the steps needs to rotate the tray body 1 for a set number of signal collection cycles; for example, the signal acquisition cycles of the entire reaction disk 100 that need to be repeated are set to 100, and then the 100 cycles are divided into corresponding steps: cleaning the cuvette 21, adding a first reagent to the cuvette 21, stirring the first reagent and the sample in the cuvette 21 for the first time, adding a second reagent to the cuvette 21, stirring the first reagent, the second reagent and the sample in the cuvette 21, if the cuvette 21 is cleaned in 10 cycles, the cleaning is stopped after the cuvette 21 is cleaned and 10 signal acquisition cycles are circulated along with the tray body 1, then the next step of adding the first reagent to the cuvette 21 is completed, and then the next signal acquisition cycle with a set number is circulated, so that the following remaining steps are completed, thereby completing the acquisition of complete optical data of one cuvette 21.

It should be noted that, in the working process of the actual biochemical analyzer, the cuvettes 21 located at different positions may perform different steps when they stop, which is not described herein again.
