Description

Technical Field

[0001] The invention relates to the technical field of culture room environment monitoring, and more specifically, to a cell culture room environment monitoring device. Background Art

[0002] Cell culture plays a vital role in many fields such as modern biology and medicine. During the cell culture process, the environmental parameters in the culture room have a key impact on the growth and development of cells, including temperature and humidity, carbon dioxide concentration, and oxygen content. In order to ensure the quality and efficiency of cell culture, it is necessary to keep the environment in the culture room in the range most suitable for cell growth.

[0003] At present, the monitoring of the cell culture room environment mainly relies on various sensors. When the scale of the cell culture room is small, using a small number of sensors to measure at specific locations can meet the monitoring needs to a certain extent. However, with the development of cell culture technology, the size of cell culture rooms has gradually increased. In this case, in order to ensure the reliability and accuracy of the measurement results, it is often necessary to place sensors at multiple locations in the culture room.

[0004] As the number of sensors increases, a series of problems arise. First, the procurement cost of sensors will rise sharply, which puts great pressure on the cost control of cell culture. Secondly, there are serious problems with the power supply method of sensors. A common power supply method is to wire multiple sensors in the culture room. This wiring method not only increases the construction cost, but also due to the special environment in the cell culture room, the cables will accelerate corrosion in a long-term environment such as humidity and heat, and there are hidden dangers such as leakage and failure, which will also pose a threat to the cell culture environment. Another power supply method is to replenish the sensor by replacing the battery, which also has problems such as corrosion, and when the number of sensors increases and the locations are dispersed, replacing the battery will become extremely labor-intensive. Especially in large-scale cell culture environments, this manual battery replacement method is inefficient and not conducive to long-term and stable environmental monitoring. Therefore, there is an urgent need for a new cell culture room environment monitoring device to solve the above problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a cell culture room environment monitoring device.

[0006] To achieve the above object, the present invention provides the following technical solution: a cell culture indoor environment monitoring device, comprising:

[0007] A track is installed in the culture chamber in a circumferential manner, and the track is fixed in the culture chamber by a plurality of fixing blocks;

[0008] A moving mechanism, wherein the moving mechanism moves in the culture chamber via a track;

[0009] A monitoring box, which is movably mounted on a mobile mechanism and can move in the culture chamber along with the mobile mechanism. A variety of sensors are arranged in the monitoring box, and the specific types of sensors are determined according to the actual conditions of different culture chambers;

[0010] The monitoring box is provided with a wireless transmission module, which can send the information monitored by the sensor to the host;

[0011] The monitoring box is also equipped with a battery for supplying power to the wireless transmission module, various sensors and driving wheels.

[0012] Furthermore, the moving mechanism includes a connecting frame, and a driving wheel and a driven wheel are installed at a position of the connecting frame corresponding to the track, the driving wheel contacts the track from above the track, and the driven wheel contacts the track from below the track, and the driving wheel can rotate;

[0013] The distance between the driving wheel and the driven wheel is smaller than the thickness of the track and larger than the thickness of the fixing block.

[0014] Furthermore, the cross section of the track is square.

[0015] Furthermore, the track includes a support frame and a rough layer wrapped on the surface of the support frame.

[0016] Furthermore, the parts of the driving wheel and the driven wheel that are in contact with the track are both provided with a rubber layer.

[0017] Furthermore, the track is divided into multiple layers, each layer is independently installed in the culture room, and a moving mechanism is arranged on each layer of the track.

[0018] Furthermore, the transmission rod includes a connecting rod A and a connecting rod B, the connecting rod A and the connecting rod B are movably connected, and two opposite sides of the connecting rod B are connected to the connecting rod B through a spring.

[0019] Furthermore, the track is arranged in the culture chamber in a continuous and circular manner up and down.

[0024] 2. In the present invention, by setting up a wireless charger in the culture room and cooperating with the wireless charging module in the monitoring box, wireless energy replenishment for the mobile mechanism and the monitoring box can be achieved, avoiding the inconvenience of traditional wiring to the location monitored by the sensor, or the tediousness of staff changing batteries back and forth.

[0035] like Figure 1-8As shown, the present invention provides a cell culture room environment monitoring device, comprising a track 2 installed around a culture room 1, and the track 2 is fixedly installed in the culture room 1 through a plurality of fixing blocks 3;

[0036] A moving mechanism 4, the moving mechanism 4 moves in the culture chamber 1 via a track 2;

[0037] The monitoring box 5 is movably mounted on the mobile mechanism 4. The monitoring box 5 can move in the culture chamber 1 along with the mobile mechanism 4. A variety of sensors are arranged in the monitoring box 5. The specific types of sensors are determined according to the actual conditions of different culture chambers 1, and are usually temperature and humidity sensors, as well as carbon dioxide and oxygen sensors.

[0038] Among them, the layout of track 2 is divided into three types.

[0039] The first case, such as Figure 1 As shown, the track 2 is installed in a single layer in a surrounding manner in the culture room 1. This situation is mainly for the culture room 1 with a low floor height, or a horizontal sensor can complete the monitoring.

[0040] The second case, such as Figure 5 As shown, the track 2 is divided into multiple layers, each layer is not interconnected, and is independently installed in the culture room 1. A moving mechanism 4 is arranged on each layer of the track 2. This situation is mainly for the culture room 1 with a high floor height or the need to monitor values ​​at different heights. Through the multi-layer track 2, multiple sensors are driven by multiple moving mechanisms 4, so that they can move horizontally and vertically in the culture room 1, so as to monitor the situation in the culture room 1 in three dimensions.

[0041] The third case, such as Figure 6 As shown, the track 2 is arranged in a continuous circle up and down in the culture room 1. This situation is also for the culture room 1 with a high floor height or the need to monitor values ​​at different heights. Unlike the second situation, a moving mechanism 4 can drive the sensor to move horizontally and vertically in the culture room 1, so that the situation in the culture room 1 can be monitored three-dimensionally, and there is no need to set a moving mechanism 4 on each layer of the track 2, thereby reducing costs.

[0042] It is worth noting that Figure 6 Although the two ends of track 2 are not connected, in actual situations, in order to reduce manual operations and achieve full automation, the two ends of track 2 can be connected.

[0043] Although the track 2 is not provided on the top of the incubator in the figure, in actual application, if necessary, the track 2 can be provided on the top of the incubator to facilitate monitoring.

[0044] A wireless transmission module is provided in the monitoring box 5, which can send the information monitored by the sensor to the host. The wireless transmission module is a prior art and will not be described in detail here.

[0045] The monitoring box 5 is also equipped with a battery for powering the wireless transmission module, various sensors and the driving wheel 42. In order to reduce the load of the mobile mechanism 4, the capacity of the battery is generally selected not to exceed 500 mAh;

[0046] The moving mechanism 4 includes a connecting frame 41, on which a driving wheel 42 and a driven wheel 43 are installed at a position corresponding to the track 2. The driving wheel 42 contacts the track 2 from above, and the driven wheel 43 contacts the track 2 from below. In order to enable the driving wheel 42 and the driven wheel 43 to run stably on the track 2, the driving wheel 42 and the driven wheel 43 are both selected to be wheels with a concave middle and convex edges on both sides.

[0047] like Figure 3 As shown, the distance between the driving wheel 42 and the driven wheel 43, which refers to the distance between the edge protrusions of the two wheels, is less than the thickness of the track 2, but greater than the thickness of the fixing block 3. The distance between the concave parts of the driving wheel 42 and the driven wheel 43 is equal to or slightly greater than the thickness of the track 2, and the driving wheel 42 and the driven wheel 43 can clamp the track 2 in the middle, so that the driving wheel 42 and the driven wheel 43 can move on the track 2.

[0048] The driving wheel 42 is capable of rotating. The driving wheel 42 itself is designed to be integrated with a motor. The principle of the rear driving wheel 42 of an electric bicycle can be referred to. This belongs to the prior art and will not be described in detail here.

[0049] The moving mechanism 4 drives the monitoring box 5 to move in the culture chamber 1, so that the sensor can move in the culture chamber 1, and a small number of sensors can perform all-round monitoring of the culture chamber 1, reducing procurement costs. The small number of sensors makes maintenance easier.

[0050] It is worth noting that the cross-section of the track 2 is square, and the driving wheel 42 and the driven wheel 43 move on a plane, which reduces the shaking of the driving wheel 42 and the driven wheel 43 during operation and increases the stability of the overall movement. In actual application, the wider the width of the track 2, the more stable the driving wheel 42 and the driven wheel 43 are during operation.

[0051] The track 2 includes a support frame 22 and a rough layer 21 wrapped around the surface of the support frame 22 . The rough layer 21 can increase the friction force of the driving wheel 42 and the driven wheel 43 when they move on the track 2 .

[0052] Similarly, in order to increase the friction force when the driving wheel 42 and the driven wheel 43 move on the track 2, a layer of rubber may be provided at the portion where the driving wheel 42 and the driven wheel 43 contact the track 2.

[0053] In order to increase the stability of the sensor driven by the connecting frame 41 to move on the track 2, the connecting frame 41 is connected to the auxiliary wheel 8 through the transmission rod 7. The auxiliary wheel 8 rotates on the track 2. The auxiliary wheel 8 is generally in contact with the upper surface of the track 2 to form a triangular support, which can increase the stability of the mobile mechanism 4 during operation.

[0054] like Figure 8 As shown, in order to enable the mobile mechanism 4 to turn better on the track 2, the transmission rod 7 includes a connecting rod A71 and a connecting rod B73. The connecting rod A71 and the connecting rod B73 are movably connected, and the two opposite sides of the connecting rod B73 are connected to the connecting rod B73 through a spring 72. When the mobile mechanism 4 needs to turn, the driving wheel 42 and the driven wheel 43 rotate first. At this time, since the auxiliary wheel 8 has not reached the corner, there needs to be an angle between the connecting rod A71 and the connecting rod B73 so that the driving wheel 42, the driven wheel 43 and the auxiliary wheel 8 can all run normally on the track 2. At this time, the connecting rod A71 rotates, compressing the spring 72 on one side and stretching the spring 72 on the other side, so that there is an angle between the connecting rod A71 and the connecting rod B73.

[0055] When the turning is completed, the connecting rod B73 and the auxiliary wheel 8 return to the same horizontal line as the driving wheel 42 and the driven wheel 43 under the elastic force of the springs 72 on both sides to restore the deformation, thereby completing the turning on the track 2.

[0056] In order to facilitate the provision of electrical energy to the mobile mechanism 4 and various sensors, a wireless charger 6 is installed at the position corresponding to the track 2 in the culture room 1, and a wireless charging module is installed in the monitoring box 5. The wireless charging module is connected to the battery. The wireless charging module replenishes the battery, which belongs to the existing technology. You can refer to the current wireless charging method of smart watches, which will not be elaborated here.

[0057] Through this wireless energy replenishment, fully automated monitoring can be achieved, human intervention can be reduced, and the problem of wiring in the culture room 1 and frequent battery replacement for the sensor can be avoided.

[0058] In addition, in order to cooperate with the battery for wireless energy replenishment, a control module is installed in the monitoring box 5. The control module can control the start of the drive wheel 42 and monitor the remaining battery power. When the battery power is low, this value can be set. For example, setting below 20% is low power. When the battery power is less than 20%, the controller controls the drive wheel 42 to move and moves the drive wheel 42 to the position of the wireless charger 6. When the control module detects that the battery is being replenished, it controls the drive wheel 42 to stop driving, thereby performing wireless energy replenishment.

[0059] In order to improve the battery life of the monitoring box 5, the components in the monitoring box 5 are all set to low power consumption. At the same time, the monitoring time of the sensor can be set in the control module. Because the sensor monitors the surrounding range, if the sensor continuously detects, there will be some overlapping monitoring areas. In actual use, the intermittent detection time of the sensor can be set according to the movement speed of the mobile mechanism 4, thereby reducing the overall energy consumption.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are within the protection scope of the technical solution of the present invention.
