After the experiment is completed, the coal retort is taken out of the furnace from the high-temperature furnace, and the coal retort is in a high-temperature state and cannot be taken down and only can be used for waiting for natural cooling, so that the experiment efficiency can be greatly reduced by the waiting time. After the coal retort is cooled to a finger-touchable state, the coal retort is disassembled according to the reverse process of the coal-charging retort, and then the next experiment can be carried out.

After the transmission shaft 510 is connected with the paddle shaft, a fixed external torque is applied to the stirring paddle 904 to realize torque transmission, so that the paddle shaft of the stirring paddle 904 is rotated with a certain torque under the constraint of the shaft sleeve 712. The top of the retort cylinder 901 is provided with an upward narrowing conical surface 710, the bottom of the inner hole of the connector body 717 is correspondingly provided with a downward expanding conical surface, and guiding connection is performed through conical surface matching. The combination and separation device 7 mainly completes automatic combination and separation with the coal retort 9. The power transmission is required to be convenient to combine and separate, namely, the power transmission is required to be synchronously connected and disconnected while the coal retort 9 is automatically combined and separated.

The end of the drive shaft 510 is provided with a slide slot 519 (as shown in fig. 4 a), the sliding coupling 514 is mounted on the end of the drive shaft 510, the pin 708 penetrates the slide slot 519 to realize the connection between the sliding coupling 514 and the drive shaft 510, and the sliding coupling 514 can move up and down along the drive shaft 510 within the slide slot 519.

The drive shaft 510 is axially positioned within the coupling body 717 by upper and lower retaining rings 702, 706, and relative rotation is achieved within the bore of the coupling body 717 by a bearing 705. As the drive shaft 510 rotates, the slip coupling 514 rotates synchronously with the drive shaft 510 under the influence of the pin 708.

A movable latch 715 is provided at the bottom of the connector body 717, the movable latch 715 is mounted on the latch base 709, the movable latch 715 includes a resilient latch 722 (as shown in fig. 4 c) capable of extending and contracting, and the movable latch 715 may be of an electromagnetic control or mechanical spring structure, as long as it is a mechanism capable of causing the resilient latch 722 to perform an extending or retracting action. The elastic pin 722 is an important part for combining and separating the coal retort 9 and the connector body 717.

During the experiment, the coal retort 9 is in a high-temperature state, and heat can be conducted to the connector body 717, the transmission shaft 510 and other accessories from the coal retort 9. In order to prevent adverse effects on thermal deformation and the like which may exist in individual kinematic systems (e.g., bearings) under high temperature conditions, heat dissipation fins 716 and heat dissipation holes 718 are further provided on the connector body 717 to dissipate the high heat of the connector body 717 by natural convection. The coupling body 717 is assembled to the arm 2 of the Gieseler fluidity tester through the mounting hole 703 of the connection plate 704, and is capable of moving up and down along with the arm 2.

Clamping and driving the coal retort 9: the top of the coal retort 9 is provided with a conical surface 710, when the coal retort 9 is combined with the connector body 717, the conical surface 710 on the coal retort 9 plays a guiding role, when the annular clamping groove 713 on the coal retort 9 and the movable clamping pin 715 are at the same horizontal height, the elastic pin 722 of the movable clamping pin 715 extends and is clamped in the annular clamping groove 713, at the moment, the combination of the coal retort 9 and the connector body 717 is completed, namely, the coal retort 9 is clamped at the lower part of the connector body 717 in a locking way. When the coal retort 9 is separated from the connector body 717, the control system releases the movable clamping pin 715 to retract the elastic pin 722, at the moment, the elastic pin 722 is separated from the annular clamping groove 713 of the coal retort 9, the coal retort 9 is separated from the connector body 717 under the action of self weight, the flat shaft 910 on the stirring paddle 904 naturally slides out of the flat groove 714 during separation, and complete separation of the coal retort 9 and the connector body 717 is completed.

The connector body 717 is provided with a limit switch 721, the limit switch 721 is triggered by a guide rod 719, the guide rod 719 is installed on the connecting plate 704, and the guide rod 719 can slide up and down through a through hole formed in the connecting plate 704 and the heat sink 716 in a matching manner. When the coal retort 9 is installed in place, the guide rod 719 moves upward for a certain distance under the action of the positioning plate 711, and the coal retort 9 is detected to be installed in place after the limit switch 721 is touched. When the coal retort 9 is taken down, the guide rod 719 moves downwards due to self weight, the signal of the limit switch 721 is released and returns to the original position, and the clamp spring 720 is arranged at the top of the guide rod 719 and used for limiting the initial position of the guide rod 719.

The detection of the limit switch 721 is limited to the determination of the presence or absence of the coal retort 9, and the quality of the combination of the coal retort 9 and the combiner body 717 cannot be identified, for example, after the coal retort 9 is installed, a gap error caused by mechanical wear may generate a non-negligible offset, or the position accuracy after clamping may be insufficient, which is considered that the coal retort 9 is not correctly combined with the combiner body 717. In order to further improve the intelligent level, the manual judgment and inspection work is reduced. A laser displacement sensor 701 is arranged above the combiner, a laser beam emitted by the laser displacement sensor 701 passes through holes formed in corresponding positions on the connecting plate 704 and the radiating fins 716, and then is directly irradiated and acted on the positioning plate 711, when the coal retort 9 is installed in place and is in a correct position, the positioning plate 711 is horizontal, and the distance between the positioning plate 711 and the laser displacement sensor 701 is a certain value; under certain conditions, when the coal retort 9 is in place and the position is deviated or slightly inclined, the distance between the positioning plate 711 and the laser displacement sensor 701 is changed, and the control system gives out alarm prompt information after detecting the existence of the error. The detection precision of the laser displacement sensor 701 can reach 0.1 mm-level precision, so that the displacement judgment has good identification performance.

In practical application, the limit switch 721 is insensitive to the detection position and has low precision, so that the limit switch is limited to detect the existence of the coal retort 9, and when the coal retort 9 and the combiner are detected to be in a processed combination state, the laser displacement sensor 701 is started to accurately identify the position of the coal retort 9. In addition, the coal retort 9 can generate large thermal deformation under a continuous high-temperature state, so that the situation that the coal retort 9 does not meet the requirements of components or experiments is caused, the displacement change situation can be detected in real time by using the laser displacement sensor 701, and prompt information is given if the displacement change situation exceeds a set range, so that the self-maintenance function of the Gieseler fluidity tester is realized.

At present, a common Gieseler fluidity measuring instrument at home and abroad can only extract a coal retort from a metal bath liquid by manpower, and then can carry out subsequent treatment after the temperature of the coal retort is naturally cooled to a temperature which can be contacted by hands; if the amount of samples is large, the task is urgent, and when the time for waiting for cooling does not exist, the coal retort in a high-temperature state can only be manually taken down from the equipment by means of protective gloves or other tools for carrying out the next group of experiments, the operation difficulty is very high, the situation that the high-temperature coal retort falls off frequently occurs, and the phenomena that operators are scalded and equipment instruments are damaged due to improper external force are easily caused. More importantly, the operator cannot leave the apparatus during the experiment, resulting in very inefficient operation.

The Kirschner fluidity tester adopts an intelligent retort frame device 6, can be matched with a mechanical arm to carry the coal retort 9, and completes the task of automatically taking and placing the coal retort 9; the state of the coal retort 9 on the retort frame device 6 can be identified, and the reliability and the safety of the experimental process are improved. The retort frame device 6 is composed of two main components, namely a lower retort frame 607 and an upper clamping frame 605, C-shaped clamping grooves are formed in the tops of coal retort clamping sleeve positions LA and RA, a clamping ring 909 is arranged on the upper portion of a retort barrel 901 of the coal retort 9, and the clamping ring 909 is arranged on the top of the C-shaped clamping groove to support the coal retort 9 on the retort frame device 6. The upper clamp frame 605 is provided with a camera 601 for image shooting, the camera 601 is connected to the driving module 603 through a support 602, and the rotation angle control of the camera 601 can be realized through the driving module 603. An infrared detector 604 is also mounted on the upper clamp frame 605.

The lower retort frame 607 is provided with a temperature sensor 611, and the temperature of the coal retort 9 is detected through the contact between the retort crucible 902 and the temperature sensor 611. Whether coal retort 9 exists on retort frame device 6 or not can be detected through cooperation of retort seat 903 and coal retort detection switch 610. An electronic display screen 606 is also installed on the retort frame device 6 and used for displaying various information. In order to identify and detect the levelness of the complete machine, a levelness sensor 608 is further installed at the bottom of the lower retort frame 607. The retort frame device 6 is integrally fixed on the base 1 of the Gieseler fluidity tester through a base 609.

The functions, the operation method and the operation process of the retort frame device 6 are as follows:

1. the mechanical arm 2 is matched to receive the coal retort 9, so that the task of automatically taking and putting the coal retort 9 is completed;

as shown in fig. 5c, the retort frame device 6 is fixed on the base 1 by its own base 609, and the centers of two coal retort clamping positions LA and RA on the retort frame device 6 are both located on the turning radius of the mechanical arm 2 with the point O as the center. The control is carried out by a control system of a Kirschner fluidity tester, the mechanical arm 2 finishes taking the coal retort 9 out of the first heating furnace 3 or the second heating furnace 4, and then the coal retort 9 is automatically placed in a corresponding coal retort clamping sleeve position on the retort frame device 6 according to a preset line; on the contrary, the mechanical arm 2 can also take the coal retort 9 off the retort frame device 6, and place the coal retort 9 into the first heating furnace 3 or the second heating furnace 4 according to a preset line. The above processes are all automatically completed without manual intervention. The operator only needs to place the prepared coal retort 9 on the coal retort clamping positions LB and LA, and then the rest tasks are executed by the control system of the Kirschner fluidity tester, so that the requirement on the operation skill of the operator is greatly reduced.

As shown in fig. 5b and 5c, the processes of taking out from the retort, charging into the furnace and discharging from the furnace are as follows: the mechanical arm 2 automatically moves to a position a1 from the central position of the heating furnace I3 along the movement track, then continues to move anticlockwise to a position a2 (the direction shown in the figure), the mechanical arm 2 ascends, the coal retort 9 is separated from the combination and separator 7, the separated coal retort 9 is placed on the retort frame device 6, and therefore the actions of discharging from the heating furnace I3 and placing the retort are completed. Similarly, the operation of taking out and putting in the retort from the second heating furnace 4 is similar to that of the first heating furnace. When the furnace entering operation is executed, an operator directly puts the prepared coal retort 9 into a coal retort clamping sleeve position on the retort frame device 6, then the mechanical arm 2 vertically descends after running to the right position, the combination and separator 7 is automatically combined with the coal retort 9, then the coal retort 9 is lifted to the position a1, clockwise rotation (the direction shown in the figure) is continued, the coal retort 9 is taken down from the retort frame device 6, and then the mechanical arm 2 puts the coal retort 9 into the first heating furnace 3 or the second heating furnace 4 according to the instruction of the control system.

2. The coal retort state on the retort frame device is identified, so that the reliability and safety of the experiment are improved;

the retort frame device 6 can be simultaneously put into 2 or 1 coal retorts 9 at the corresponding positions LB and LA. Specifically, the method comprises the following steps: the mechanical part of the retort frame device 6 mainly comprises an upper clamping frame 605 and a lower retort frame 507, wherein the upper clamping frame 605 is used for matching with a clamping ring 909 on the coal retort 9, when the coal retort 9 is put on the retort frame device 6, the coal retort 9 is put on the upper clamping frame 605, and meanwhile, the clamping ring 909 is matched with a positioning groove on a positioning block 612, so that the coal retort 9 is prevented from changing the horizontal position.

And (3) detecting the temperature of the coal retort: after the high-temperature coal retort 9 taken out of the heating furnace is placed on the retort frame device 6 by the mechanical arm 2, scalding accidents can happen if an operator takes away the coal retort 9 by hands directly, so that a temperature sensor 611 is arranged on the retort frame device 6 corresponding to the bottom of the coal retort 9, and after the coal retort 9 is placed on the retort frame device 6, the temperature sensor 611 is in direct contact with the bottom of the retort crucible 902 on the coal retort 9. In order to ensure gapless contact, a spring mechanism is arranged, when the retort crucible 902 vertically moves downwards, the spring 6113 can always keep contact with the temperature sensor 611, and the continuity and the real-time performance of temperature measurement are ensured.

The retort frame device is provided with a coal-free retort detection device: the coal retort detection switch 610 arranged on the retort frame device 6 is used for detecting whether the coal retort 9 exists on the retort frame device 6. When the coal retort 9 is placed in the retort frame device 6, the bottom of the retort seat 903 below the retort crucible 902 directly touches the guide post 6102, the guide post 6102 slides down in the sliding sleeve 6101 due to the self weight of the coal retort 9 and acts on the microswitch shrapnel 6105, so that the microswitch 6104 obtains a trigger signal, and when the coal retort 9 is taken away, the guide post 6102 returns to the original position under the elastic action of the microswitch shrapnel 6105.

Logical diagnostic guard: the mechanical arm 2 takes the coal retort 9 from the retort frame device 6 and puts the coal retort 9 into the heating furnace, or the high-temperature coal retort 9 is lifted out of the heating furnace and put into the retort frame device 6, and the situation that the mechanical arm 2 is stuck or accidents occur in the motion process can exist. Since the time for the robot arm 2 to move according to the predetermined target point is fixed and the path for the robot arm to move along the set trajectory is also fixed, the time for the robot arm to pass through or reach each predetermined target point is fixed. When the robot arm 2 does not arrive or arrives in advance within a predetermined time in a certain process, it means a possibility of occurrence of a mechanical failure. To prevent the fault from expanding, the control system diagnoses the logic all the time, and when the condition is met, the control system stops the motion of each motion system immediately and displays the prompt information through the electronic display screen 606.

Judging the levelness of the whole machine: the retort frame device 6 is provided with a levelness sensor 608, and when the retort frame device 6 is installed on the base 1, the retort frame device is connected with the Gieseler fluidity tester into a whole. The levelness sensor 608 is used for detecting the levelness of the whole machine, and if the levelness exceeds a set limit value, the system cannot enter a working state, so that a large deviation of an experimental result is prevented.

And (3) information display: an electronic display screen 606 is arranged on the lower retort frame 607 and used for displaying various information in real time when the equipment works, and an operator can know the running state of the system at the first time according to the information displayed on the screen. The temperature of the coal retort 9 is displayed on the electronic display screen 606 at any moment, and when the temperature of the high-temperature coal retort 9 on the retort frame device 6 is reduced to a safe temperature (when a hand can touch the high-temperature coal retort 9), a safety prompt message is also given.

The process state is judged intelligently, and misoperation is prevented: after the experiment process is completed, the high-temperature coal caldron is placed on the caldron frame device and is cooled to the safe temperature, and under the normal condition, the coal caldron which is completed with the experiment is taken away by an operator and cleaned, and then a new sample is loaded again to continue the next experiment. In actual practice, the coal retort may be re-tested without cleaning due to operator negligence. In order to avoid the above situation, after the coal retort is put on the retort frame, the control system starts to automatically record the following conditions:

1) the coal retort conforms to the high-temperature characteristic;

2) the coal retort is put on a retort frame by a mechanical arm;

3) the coal retort stays on the retort frame continuously until the coal retort is cooled to the temperature below the normal temperature.

After at least three conditions are met, the control system can temporarily lock the corresponding coal retort, and if an operator does not take down and clean the coal retort all the time, relevant information can be continuously displayed on the electronic display screen. In the process, if someone mistakenly operates the coal retort but does not take the coal retort away for cleaning, locking type identification of the coal retort in a short distance is carried out through the camera, and if the coal retort is not replaced in a certain sight range, the effectiveness of prompting is continuously kept.

Providing relevant parameter conditions to a control system; when two coal steamers are placed on the retort frame, the first Kirschner fluidity test is carried out first and then, when the retort frame detects that two coal steamers are placed, and before the experimental process that the first coal steamers are placed in the first heating furnace is finished, the second heating furnace is started by the control system in advance for preheating, so that the working efficiency is greatly improved. The function is realized by the detection switch and the temperature sensor on the retort frame respectively providing detection information to the control system and carrying out logic operation and condition judgment by the control system.

3. Self-protection, safety protection and remote intelligent cooperation;

the self-protection refers to a corresponding protection measure taken when various logic contradiction conflicts are encountered during the working period of the instrument, and particularly refers to a coping mechanism aiming at various conditions of potential damage of the instrument.

Resolution of logical conflict mechanism: the detection switch is used for identifying and judging the motion conflict logic of the coal retort and the mechanical arm, and the conflict logic mechanism has many results and is only described as a typical case:

when the instrument works, an operator mistakenly puts another coal retort on the retort frame, and the detection switch detects the existence of the coal retort; when the experiment is finished, the mechanical arm takes the coal retort to be discharged and puts the coal retort which is just discharged on the retort frame, and if the action is executed unconditionally, the coal retort is damaged due to collision. The counter measures are as follows: once the coal retort is detected to be on the retort frame, the control system judges which coal retort clamping sleeve position is a vacant position, and the mechanical arm places the high-temperature coal retort which is just discharged to the vacant coal retort clamping sleeve position. If no idle coal retort clamping sleeve position exists on the retort frame, the mechanical arm moves to a specific standby position and stops, and the action of putting the coal retort on the retort frame is interrupted, so that physical hardware is protected from being damaged. And meanwhile, the control system can also give information display corresponding to the current situation for prompting an operator. The control system can also time the high-temperature coal retort on the mechanical arm at present, and prompt the current temperature of the coal retort for an operator according to the natural cooling speed of the high-temperature coal retort in the air. When the temperature of the coal retort is reduced to the safe temperature, an operator can directly take the coal retort off from the mechanical arm.

When the coal caldron is taken out of the heating furnace by the mechanical arm, the control system immediately starts the infrared detector, the infrared detector detects the human body movement within a certain distance range, when a person is very close to the mechanical arm at a certain moment, and the mechanical arm is likely to be touched to cause the possibility of high-temperature scald as long as the mechanical arm starts to move, the infrared detector immediately suspends the current movement of the mechanical arm through the control system and immediately sends sound alarm and text alarm information to the electronic display screen. And when the person leaves the infrared detector and keeps a safe distance, the control system controls the mechanical arm to continuously complete subsequent tasks.

Login authorization: the intelligent Gieseler fluidity tester needs to be operated by a professional operator, and the possibility of operation by unauthorized persons must be prevented. The human face is scanned by using the camera, then the human face is compared with the pre-stored data in the control system, when the data is valid, the login is automatically authorized, and the operator has the right to operate the equipment.

There are several main factors influencing the results of the coriolis fluidity measurement, and the most important core is the torque calibration, and at present, hand-held torque calibrators (a torque meter) are mostly used at home and abroad for calibration, and in addition, a strain-gauge-based sensor, that is, a method of indirectly measuring by using an electronic pressure or tension sensor (hereinafter, referred to as an electronic method) is also used. The electronic type has the defects that the measured torque is small, the influence of environmental factors is large, and the error fluctuation and uncertainty of the sensor are caused, so that the self calibration is required before the electronic type is used, otherwise, a large error exists, and the complexity degree of operation is increased. The sensitivity of the handheld torque calibrator is reduced when the handheld torque calibrator conforms to the measuring range of the output torque, and more importantly, the handheld torque calibrator is completely operated by manpower when in use, so that the requirement on operators is higher. Furthermore, the highest measurement accuracy of such a hand-held torque calibrator is ± 5%, which is already at the limit of the maximum error requirement for calibration from this index, which is obviously impossible to achieve if higher accuracy is to be achieved. In addition, the two measurement modes have a commonality, namely the measurement process does not meet the requirements of GB and ISO related standards, the output shaft is ensured to rotate at least one circle when the torque is required to be measured in the standards so as to verify whether the torque output within the range of 360 degrees meets the requirements, the electronic type only measures one point on the circumference, and the handheld torque calibrator needs to measure for multiple times if the torque is required to meet the requirements.

The Gieseler fluidity tester is provided with the micro torque automatic calibrator, can intelligently calibrate the torque in a full speed range through an algorithm, can automatically calibrate the torque in the whole process, has a calibration process visible by naked eyes, and supports manual undisturbed re-inspection.

The extending end of the horizontal rod 802 is provided with a short shaft 814, and the driven wheel 803 is sleeved on the short shaft 814 through a bearing. The bearing is a miniature low-resistance bearing. One end of the monofilament line 801 is fixed to a monofilament line fixing point P on the driving wheel 811, and when the driving wheel 811 rotates clockwise (in the illustrated direction), the monofilament line 801 is wound around the driving wheel 811, and after the monofilament line 801 passes around the driven wheel 803, a weight 806 is tied to the end of the other end of the monofilament line, and at this time, the weight 806 is lifted by the clockwise rotation of the driving wheel 811.

The mass of the weight 806 determines the amount of torque on the sleeve 712 that is directly connected to the drive wheel 811. I.e., the greater the mass of the weight 806, the greater the torque that needs to be applied to the sleeve 712. Therefore, the construction principle of the torque calibrator is simple, namely the principle of weight mass balance is used, when the weight rises, the torque on the shaft sleeve is larger than the static moment generated by the weight, and vice versa.

The normalized torque value in the Kirschner fluidity measurement according to the GB and ISO-related standards was 101.6. + -. 5.1 g.cm, (i.e., 0.00996. + -. 0.0005 N.M), and assuming that the effective diameters of the driving and driven pulleys were 50.8mm, the weight mass was 40g when the normalized torque was generated. The perimeter of one circle of rotation of the driving wheel is 160mm, and the vertical distance between the upper limit point position H and the initial point position Z of the weight 8 can be obtained by measuring through an encoder; when the weight has a mass of 40g and is suspended at any point between the H point and the Z point, the torque corresponding to the weight of 40g is 101.6g.cm theoretically, ignoring the influence of the frictional resistance and the self-mass of the monofilament thread. Meanwhile, according to the relevant standards, the above-mentioned torque error is ± 5.1g · cm, and the converted weight mass is ± 2g · cm, and therefore, when the weight is 38g to 42g, the range is within the allowable range.

The base 1 is connected with a support plate 810 through a fastener 808 and a column 809, the support plate 810 is used for placing a driving wheel 811, in order to prevent the driving wheel 811 from excessively shifting when moving upwards under the action of a transmission shaft 510, a separation baffle 812 is arranged above the driving wheel 811, and the separation baffle 812 is not in contact with the driving wheel 811 in the normal checking process. The driving wheel 811 has a hole at its edge for fixing one end of the monofilament line 801 and establishing a connection with the driven wheel 803 via the monofilament line 801, the driven wheel 803 has a stub 814 at one side thereof, the stub 814 is provided with a miniature low-resistance bearing, and the driven wheel 803 is mounted on the stub 814 via the miniature low-resistance bearing, so that the driven wheel 803 has minimal rotational damping. In order to measure the moving distance of the weight 806, an encoder 804 is mounted on a short shaft 814 of the driven wheel 803, so that the measurement of the rotational displacement is realized. In order to prevent the weight 806 from being influenced by external force such as wind, a shield 805 is provided, and the shield 805 is made of transparent acrylic material, which is beneficial for direct observation of an operator. When the weight 806 falls back to the initial position, it is detected by the proximity switch 807.

The working principle of the intelligent Gieseler fluidity tester is as follows: putting a certain amount of coal samples into the coal retort 9, then putting the coal samples into the alloy bath liquid 13 at a certain temperature, then heating the coal retort 9 at a certain heating rate to heat the coal samples, and applying a constant torque to the coal samples in the process to measure the coal fluidity to serve as a final experiment result.

The combination and separation device 7 is fixed on the constant-torque transmission device 5 and mainly has the function of automatically separating and combining with the coal retort 9 so as to enable the coal retort 9 to be taken to a specified position under the action of a motion system.

The control system is a control part of the equipment and consists of a controller, a computer and the like.

Planning of motion trail and identification and decision of motion logic: because fixed point type movement is involved and multi-task self-decision is also made, the movement track of the movement system per se must be standardized, and faults such as collision, mutual interference and the like in the movement process are avoided. FIG. 7 is a plan view of the movement locus of the intelligent Gieseler fluidity tester, which is a planar development figure, all possible target working points are represented by coordinates, and the moving target and the locus of the motion system move under the locus formed by the coordinates.

And then the control system controls the heating furnace to automatically heat up, and the fluidity of the coal is measured.

2. Taking out of the coal retort:

when the characterization measurement is completed after the coal sample is solidified into semi-coke, the motion system is vertically lifted from the (x1, y8) position to the (x1, y0) position, then moves to the (x3, y6) position after passing through the (x2, y0) and the (x2, y6) two points, and then vertically lifted to the (x3, y0) position, and at this time, the motion system already puts the high-temperature coal steamer on the LA position of the steamer frame. At this point, a duty cycle is complete, and then the kinematic chain is left at the standby position by itself passing through point (x2, y0) and returning to point (x2, y 6).

3. Two-furnace continuous experiment:
