Technical Field
[0001] This utility model relates to the field of bioreactors, and in particular to an optical sensor detection system. Background Technology
[0002] In the field of bioreactors, in order to detect bioprocess parameters such as dissolved oxygen content, pH value, and carbon dioxide content in the solution inside the reactor, a reactor often needs to be equipped with two or more non-invasive optical sensor modules of different types. However, the setting of multiple optical sensor modules will make the entire bioreactor too large, affecting its practicality. In addition, due to the high price of optical sensor modules, bioreactors equipped with optical sensor modules are expensive. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model discloses an optical sensor detection system.
[0004] An optical sensor detection system for detecting bioprocess parameters in a reactor includes an optical fiber module, at least one optical sensor, and at least one detection patch attached to the reactor. The optical fiber module includes a first optical fiber, a second optical fiber, and a switching element. The first optical fiber is connected to the detection patch and corresponds to it in a one-to-one manner. The second optical fiber is connected to the optical sensor in a one-to-one manner. The switching element is used to enable the first optical fiber / second optical fiber to transmit signals with different second optical fibers / first optical fibers.
[0005] Specifically, by using a switching element, the first optical fiber / second optical fiber can transmit signals with different second optical fibers / first optical fibers, thereby transmitting the detection data of different detection patches connected to different first optical fibers to the same optical sensor, realizing one-to-many optical sensor. This structure can effectively reduce the number of optical sensors, which can not only greatly reduce the size of the optical sensor detection system, but also significantly reduce the price of the optical sensor detection system, making the optical sensor detection system more practical.
[0006] Preferably, the switching component includes a fixed fiber optic plate and a movable fiber optic plate, the movable fiber optic plate being movable relative to the fixed fiber optic plate; the first fiber optic plate is fixed on the fixed fiber optic plate, and the second fiber optic plate is fixed on the movable fiber optic plate. When the movable fiber optic plate moves to enable signal transmission between the first fiber optic plate and the second fiber optic plate, the detection data of the detection patch connected to the first fiber optic plate is transmitted to the optical sensor connected to the second fiber optic plate.
[0007] Specifically, the structure of setting up a fixed fiber optic board and a movable fiber optic board makes switching between the first fiber and the second fiber more convenient.
[0008] Preferably, the end face of the movable fiber optic plate is always parallel to the end face of the fixed fiber optic plate. The first fiber optic cable passes through the fixed fiber optic plate in the direction of the movable fiber optic plate, and the second fiber optic cable passes through the movable fiber optic plate in the direction of the fixed fiber optic plate. Signal transmission is achieved when the first fiber optic cable and the second fiber optic cable are connected.
[0009] Specifically, in this structure, the first optical fiber and the second optical fiber are directly connected to achieve signal transmission, and the parallel movable optical fiber plate and the fixed optical fiber plate make the position control of the movable optical fiber plate more convenient and accurate.
[0010] Preferably, the sum of the length of the first optical fiber passing through the fixed movable plate and the length of the second optical fiber passing through the movable optical fiber plate does not exceed the gap between the fixed optical fiber plate and the movable optical fiber plate.
[0011] Specifically, this structure is designed to prevent the protruding length of the first or second optical fiber after passing through the fixed or movable optical fiber plate from interfering with the movement of the movable optical fiber plate.
[0012] Preferably, the fixed fiber optic plate has a first groove for fixing the end of the first fiber optic cable away from the detection patch, and the movable fiber optic plate has a second groove for fixing the end of the second fiber optic cable away from the optical sensor. When the first groove and the second groove are matched, the corresponding first fiber optic cable and the second fiber optic cable can transmit signals.
[0013] Specifically, signal transmission can also be achieved through indirect connection between the first and second optical fibers, thus this structure has a certain degree of practicality.
[0014] Preferably, the first optical fiber and the second optical fiber are connected by an adapter to achieve signal transmission.
[0015] Preferably, it further includes a drive module for driving the movement of the movable fiber optic plate; the drive module includes a sliding module for the movable fiber optic plate to slide, and a power module for driving the movable fiber optic plate to slide on the sliding module; the power module includes a drive motor and a transmission mechanism, the sliding module includes a slide rail and a slider, the slider is fixed to the transmission mechanism and moves with the movement of the transmission mechanism, and the movable fiber optic plate is fixed on the slider.
[0016] Specifically, in this structure, the movable fiber optic plate moves along the track direction of the slide rail, which can effectively ensure the stability of the movable fiber optic plate during movement. The structure driven by the drive motor can effectively ensure the accuracy of the movement of the movable fiber optic plate, ensuring that the second fiber can accurately connect with the target first fiber.
[0017] Preferably, the moving direction of the movable fiber optic plate is controlled by the rotation direction of the drive motor.
[0018] Preferably, it also includes a base plate, on which the drive motor and slide rail are fixed.
[0019] Specifically, the fiber optic board can also be fixed to the base plate.
[0020] Compared with the prior art, the advantages of this utility model are:
[0021] The switching mechanism allows one second optical fiber to be connected to multiple first optical fibers, enabling data from multiple detection patches to be transmitted to a single optical sensor. This achieves a one-to-many optical sensor configuration, effectively reducing the number of optical sensors required. This not only significantly reduces the size of the optical sensor detection system but also substantially lowers its price, making the system more practical. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] like Figure 1-4 As shown, an optical sensor detection system is used to detect bioprocess parameters in a reactor 10. It includes an optical fiber module, at least one optical sensor 20, and at least one detection patch 30 attached to the reactor 10. The optical fiber module includes a first optical fiber 41, a second optical fiber 51, and a switching element. The first optical fiber 41 is connected to the detection patch 30 and corresponds to it one-to-one. The second optical fiber 51 is connected to the optical sensor 20 and corresponds to it one-to-one. The switching element is used to enable the first optical fiber 41 / second optical fiber 51 to transmit signals with different second optical fibers 51 / first optical fibers 41.
[0028] By using a switching device, the first optical fiber 41 / second optical fiber 51 can transmit signals with different second optical fibers 51 / first optical fibers 41, thereby transmitting the detection data of different detection patches 30 connected to different first optical fibers 41 to the same optical sensor 20, realizing one-to-many optical sensor 20. This structure can effectively reduce the number of optical sensors 20, which can not only greatly reduce the size of the optical sensor 20 detection system, but also significantly reduce the price of the optical sensor detection system, making the optical sensor detection system more practical.
[0029] The switching device includes a fixed fiber optic plate 40 and a movable fiber optic plate 50, which can move relative to the fixed fiber optic plate 40. The first fiber optic plate 41 is fixed on the fixed fiber optic plate 40, and the second fiber optic plate 51 is fixed on the movable fiber optic plate 50. When the movable fiber optic plate 50 moves to enable signal transmission between the first fiber optic plate 41 and the second fiber optic plate 51, the detection data of the detection patch 30 connected to the first fiber optic plate 41 is transmitted to the optical sensor 20 connected to the second fiber optic plate 51.
[0030] The structure of the fixed fiber optic board 40 and the movable fiber optic board 50 makes the switching between the first fiber 41 and the second fiber optic board 51 more convenient.
[0031] The end face of the movable fiber optic plate 50 is always parallel to the end face of the fixed fiber optic plate 40. The first fiber 41 penetrates the fixed fiber optic plate 40 in the direction of the movable fiber optic plate 50, and the second fiber 51 penetrates the movable fiber optic plate 50 in the direction of the fixed fiber optic plate 40. Signal transmission is achieved when the first fiber 41 and the second fiber 51 are connected.
[0032] In this structure, the first optical fiber 41 and the second optical fiber 51 are directly connected to realize signal transmission, and the parallel movable optical fiber plate 50 and the fixed optical fiber plate 40 make the position control of the movable optical fiber plate 50 more convenient and accurate.
[0033] The sum of the length of the first optical fiber 41 passing through the fixed movable plate 40 and the length of the second optical fiber 51 passing through the movable optical fiber plate 50 shall not exceed the gap between the fixed optical fiber plate 40 and the movable optical fiber plate 50.
[0034] This structure is designed to prevent the protruding length of the first optical fiber 41 or the second optical fiber 51 after passing through the fixed optical fiber plate 40 or the movable optical fiber plate 50 from interfering with the movement of the movable optical fiber plate 50.
[0035] The fixed fiber optic plate 40 is provided with a first groove for fixing the end of the first fiber optic 41 away from the detection patch 30, and the movable fiber optic plate 50 is provided with a second groove for fixing the end of the second fiber optic 51 away from the optical sensor 20. When the first groove and the second groove are matched, the corresponding first fiber optic 41 and second fiber optic 51 realize signal transmission.
[0036] Signal transmission can also be achieved through an indirect connection between the first optical fiber 41 and the second optical fiber 51, thus this structure has a certain degree of practicality.
[0037] The first optical fiber 41 and the second optical fiber 51 are connected by an adapter to achieve signal transmission.
[0038] It also includes a drive module for driving the movement of the movable fiber optic plate 50; the drive module includes a sliding module for the movable fiber optic plate 50 to slide, and a power module for driving the movable fiber optic plate 50 to slide on the sliding module; the power module includes a drive motor 61 and a transmission mechanism 62, the sliding module includes a slide rail 63 and a slider 64, the slider 64 is fixed to the transmission mechanism 62 and moves with the movement of the transmission mechanism 62, and the movable fiber optic plate 50 is fixed on the slider 64.
[0039] In this structure, the movable fiber optic plate 50 moves along the track direction of the slide rail 63, which can effectively ensure the stability of the movable fiber optic plate 50 during the movement. The structure driven by the drive motor 61 can effectively ensure the accuracy of the movement of the movable fiber optic plate 50, and ensure that the second fiber optic plate 51 can accurately dock with the target first fiber optic plate 41.
[0040] The direction of movement of the movable fiber optic board 50 is controlled by the rotation direction of the drive motor 61.
[0041] It also includes a base plate 70, a drive motor 61, and a slide rail 63, all of which are fixed on the base plate 70; the fixed fiber optic plate 40 can also be fixed on the base plate 70.
