Description

Technical Field

[0003] If the supervision and control of the above-mentioned systems rely entirely on manual operation, it would be labor-intensive and inconvenient. Therefore, most of the systems are currently controlled semi-automatically or automatically through controllers at various levels. However, taking the lighting system as an example, this has the following shortcomings: Currently, for energy-saving considerations, lamps in many scenarios are designed to be controlled by sound sensors, light sensors, etc. Although such designs can achieve certain energy-saving effects, the working mode is relatively rigid, and it is easy for people to need lighting but the system automatically turns off the lights. If defects such as the above-mentioned lighting system occur in laboratory buildings and not only lighting, but also other ventilation, etc. may affect the normal experimental process, but many electromechanical equipment do not have automatic power on and off management, and rely on regulations and self-consciousness. The annual energy consumption expenditure of laboratories is often very large. Therefore, this application proposes a new technical solution. Summary of the Invention

[0016] The following is combined with Figure 1-7 This application is described in further detail.

[0017] The embodiment of the present application discloses a high-efficiency energy-saving control system based on laboratory building electromechanical equipment.

[0018] Reference Figure 1 , based on the laboratory building electromechanical equipment efficient energy-saving control system includes: A data acquisition module, which is used to collect on-site data of the target monitoring area corresponding to several electromechanical equipment in the laboratory building; The above-mentioned field data, for example: environmental parameters in the monitoring area, power consumption of each device, and air pressure change value in the monitoring area; monitoring areas, such as: experimental work area, sample preparation area, sample storage room, etc.

[0019] The control center is connected to the data acquisition module and is used to analyze and process the field data; The control center is composed of the server in the laboratory building. The control center is connected to the data acquisition module in a wired manner to obtain field data in the monitoring area.

[0020] Energy consumption supervision response module, which is deployed in the target monitoring area and connected to the control center; Reference Figure 1 and Figure 2 The energy consumption monitoring and response module includes environmental parameter adjustment devices, such as refrigeration and air conditioning units, humidifiers, and solenoid valves installed in the monitored area's circuits. The energy consumption monitoring and response module is connected to the control center via a wired connection, enabling control of the monitored area through the module. The data acquisition module includes multiple electrical parameter detection units 1, with at least one corresponding to any target area. These units are installed at the intersection of the power bus and branch circuits in the target area and are used to detect the electrical parameters of each branch circuit.

[0021] The control center is configured as: Add identification tags to multiple target monitoring areas based on user interaction data and bind each target area. Functional type of the target monitoring area; The above-mentioned identification labels are added to multiple target monitoring areas. For example, the monitoring area on the first floor is divided into a, the monitoring area on the second floor is divided into b, and the monitoring area on the third floor is divided into c, and so on. According to the floor of the monitoring area, the letters a, b, c...z are corresponding in sequence. The monitoring areas on each floor are sorted from 1, 2...n in sequence. For example, the first monitoring area on the first floor is marked as a1, the second monitoring area on the first floor is marked as a2, and the first monitoring area on the second floor is marked as b1. And so on. The label of each monitoring area is obtained by combining the letter represented by the floor number and the position on the floor.

[0022] The staff binds the functional type of each target monitoring area according to the different experimental equipment, experimental environment, experimental objectives, etc. arranged in each target monitoring area. For example: the area equipped with storage boxes, ultra-low temperature refrigerators and other equipment for sample storage is divided into sample storage rooms; the area equipped with ultraviolet disinfection devices, dry heat sterilization boxes and other equipment for sample disinfection and sterilization is divided into sample disinfection rooms; the experimental area equipped with spectrometers, chromatographs and other equipment dedicated to sample experiments and analysis is divided into experimental areas.

[0023] The control center marks the floors where each area is located and its position on the corresponding floor, which is uploaded to the control center by staff on personal terminals via the Internet, and adds identification tags to multiple target monitoring areas.

[0024] Based on the identification tag of the target monitoring area, determine its matching function type, and search the preset database according to the function type to obtain the matching power supply plan; Power supply plan example: The function type matched by label a3 is a medium-to-large laboratory (which contains at least four sets of equipment used for the same experiment). The database records its power supply plan as follows: lighting fixtures are fully turned on by voice control or human body sensing, ventilation devices are fully turned on, and all sets of equipment are in the powered-on state. The function type matched by label b1 is a cold storage room. The database records its power supply plan as follows: lighting responds to voice control, and automatically switches to backup power after power failure, with a priority of level one.

[0025] Obtain electrical parameters and determine the matching target area based on the device ID and pre-uploaded device installation records. Bind identification tags to the corresponding target areas and generate a regional electrical parameter set. Each device is equipped with a different ID (i.e., production number, etc.). During installation, the staff will record the floor where the device is installed and its location on the floor and upload it to the control center through the network. The corresponding target area is obtained based on the floor where the device is installed and its location on the floor. The target area is then bound to the identification tag of the target area. Characters are added to the identification tag to facilitate staff differentiation of devices. For example, the first laboratory on the first floor is a drug storage room with an identification tag of a1. The lighting equipment in the drug storage room is marked as a1-01, the ventilation equipment is marked as a1-02, and so on, for easy differentiation.

[0026] Analyze the real-time regional power parameter set based on the preset energy-saving logic and make corrections to the power supply plan; Energy saving logic example: Analyze whether there are independent power facilities with the same function in the area corresponding to any tag. If so, power off any unused facilities; or if there are matching independent lighting, only keep the lighting. Determine whether the functional type of the area corresponding to any tag meets the preset first-level priority power supply conditions. If so, maintain the original power supply plan, and when the building power supply is abnormal, cut off the area that is not the first-level priority power supply.

[0027] Based on the above, an example of correcting the power supply scheme is as follows: A3 The power supply solution for medium and large laboratories is as follows: lighting fixtures are fully turned on upon voice control or human presence detection, ventilation devices are fully turned on, and each set of equipment is in a powered-on state. At this time, the staff only uses one piece of equipment. The correction is: for one set of equipment used by the staff, the power of other equipment is cut off and only the lighting is retained; even under the premise that the lighting power is adjustable, the independent lighting power corresponding to other sets of equipment is reduced to 40-50% of the original.

[0028] The power supply scheme for the b1 cold storage room is as follows: lighting responds to voice control, and after a power outage, it automatically switches to the backup power supply with a priority of level 1. At this time, the building has a power supply anomaly; Correction: Maintain the original power supply plan and keep the power supply.

[0029] The energy consumption supervision response module is controlled based on the corrected power supply plan.

[0030] Based on the above content, this system adds identification tags to multiple target areas and determines the power supply plan according to their functional types. Through the data acquisition module, it is convenient to obtain the usage of equipment in the target area in real time, compare the laboratory equipment usage registered by the staff for laboratory appointments with the electrical parameter set generated by the actual target area, correct the usage of laboratory equipment based on the preset energy-saving logic, and control it through the energy consumption supervision response module.

[0031] Reference Figure 2 and Figure 3 In another embodiment of the present application, the electrical parameter detection unit 1 includes: a control box 11, a current sensor, a drive motor 2, an adjustment mechanism 3 and a drive mechanism 4. The cables corresponding to each branch circuit are branch cables, and any branch cable is paralleled by a bypass cable.

[0032] The current sensors cover all branch cables, and there are at least two of them, one is the current sensor B112, and the other is the current sensor B213. The current sensor in this embodiment can be a Hall sensor. The adjustment mechanism 3 is electrically connected to all branch cables and is located between the current sensor B112 and the current sensor B213. The adjustment mechanism 3 is used to change the on / off state of each branch cable in the point electrical connection area, and the adjustment mechanism 3 can only make one branch cable conductive at a time.

[0033] The bypass cables are routed around the current sensor B213 and the adjustment mechanism 3. The control box covers the adjustment mechanism 3 and current sensor B213 and is penetrated by the branch cables. The drive motor 2 is bolted to the outside of the control box 11 and electrically connected to the control center. The drive mechanism 4 is connected to the drive motor 2 and the adjustment mechanism 3 and is used to drive the adjustment mechanism 3 to sequentially adjust the branch cables according to the number of rotations of the drive motor 2's output shaft. The branch cables are distributed circumferentially.

[0034] The controller configuration is: Define multiple branch cables of any target monitoring area as A1, A2...An, and the numbering order of A1, A2...An is the circumferential order of the branch cables; where n is the total number of branch cables in the target monitoring area; An is determined by the total number of branch cables in the target monitoring area. If there are 8 branch cables in the target monitoring area, the maximum number is A8.

[0035] Define the branch cable that is conductive when the adjustment mechanism 3 is in the initial state as A1; Obtain historical control parameters of the drive motor 2 and determine the branch cable An currently conducting of the regulating mechanism 3; Example: If the total number of branch cables in the target area is 4, the branch cables are numbered A1, A2, ..., A4. If the historical control parameter of the drive motor 2 (i.e., the number of rotations of the output shaft of the drive motor 2) is 2, the branch cable currently connected by the adjustment mechanism 3 is A3.

[0036] Obtaining the current detection values ​​of the current sensor B112 and the current sensor B213, which are respectively referred to as detection data 1 and detection data 2; If the detection data 1 meets the preset power consumption condition, the current detection data 2 is bound to An, and the drive motor is controlled to drive the adjustment mechanism to conduct the branch cable An+1, and is bound to the corresponding detection data 2; The above operation is repeated until all branch cables are traversed and a set of regional electrical parameters is obtained.

[0037] The above-mentioned power usage conditions refer to the current sensor detecting that current is flowing. On the basis of the above, the branch cable connected by the current regulating mechanism 3 is A3, and the detection data 2 is x1, and it is recorded. The regulating mechanism 3 is driven by the driving motor 2 to connect the branch cable A4, and the detection data 2 is x2. The driving motor 2 drives the regulating mechanism 3 to connect the branch cable A1, and the detection data 2 is x3. The regulating mechanism 3 is driven by the driving motor 2 to connect the branch cable A2, and the detection data 2 is x4. When the driving motor 2 drives the regulating mechanism 3 to connect the branch cable A3 again, the technology of sequentially connecting the regulating mechanism 3 is completed by the counter preset in the control center, and the acquisition of the detection data 2 is stopped, and the detection data 2 (x1, x2, x3 and x4) of each branch cable connected are added in sequence to obtain the regional electrical parameter set.

[0038] Through the above-mentioned setting, the regulating mechanism 3 changes the on / off state of each branch cable in turn under the driving action of the driving mechanism 4. By recording the detection values ​​fed back by the detection data 2 when each branch cable in the target monitoring area is turned on, and summarizing them, a regional electrical parameter set is obtained, so as to adjust the power supply plan according to the regional electrical parameter set.

[0039] Reference Figure 3 and Figure 4 In one embodiment of the present application, the adjustment mechanism 3 includes an adjustment disk 31, an adjustment rod 32 and a plurality of connecting blocks 33. The two ends of the adjustment rod 32 are respectively fixedly connected to the inner walls on both sides of the inner cavity of the control box 11, and the adjustment rod 32 is extended in the opposite direction of the branch cable. By fixing a plurality of connecting blocks 33 on each branch cable in the control box 11, the connecting block 33 is located between the bypass cable and the current sensor B213, and a groove 34 is provided on the side wall of the connecting block 33 to separate the two ends of the branch cable in the control box 11. The adjustment disk 31 is rotatably mounted on the adjustment rod 32, and an extension disk 36 is provided on the side wall of the adjustment disk 31 along its circumference, and the side edge of the extension disk 36 extends into the groove 34.

[0040] A limiting groove is provided through the side edge of the extension disk 36, and a conductive sheet 35 is fixedly provided in the limiting groove. The two ends of the conductive sheet 35 are respectively in contact with the inner walls on both sides of the branch cable partition, and the extension disk 36 and the adjustment disk 31 are both made of insulating materials, so that the branch cables in the control box 11 can only be connected in sequence through the conductive sheet 35, and because the side walls on both sides of the extension disk 36 are in contact with the inner walls on both sides of the branch cable partition, leakage is prevented, and at the same time, the current sensor B213 can detect the branch cables in sequence.

[0041] Since the side edge of the extension disk 36 extends into the groove 34 and fits against the inner walls on both sides of the disconnection point of each branch cable, each branch cable cannot be conductive at the current sensor B213. Only when the conductive sheet 35 fixedly arranged on the extension disk 36 extends into the groove 34, the corresponding branch cable can be conductive, so as to achieve the purpose of individual conductivity of each branch cable detected by the current sensor B213, and each branch cable can still be conductive through the bypass cable located outside the current sensor B213, so as to facilitate the monitoring of equipment in working condition in the target area.

[0042] Reference Figure 3 、 Figure 5 as well as Figure 6 The driving mechanism 4 includes a lifting assembly 41, a driving disk 42 and a switching assembly 43. The driving disk 42 is rotatably sleeved on the adjusting rod 32. The lifting portion of the lifting assembly 41 is slidably penetrated by the control box 11, and one end of the lifting assembly 41 extending out of the control box 11 is connected to the output shaft of the driving motor 2 by setting a connecting assembly 44. One end of the lifting assembly 41 located in the control box 11 is hinged to the side edge of the driving disk 42. The output shaft of the driving motor 2 drives the lifting and lowering of the lifting assembly 41, so that one side of the driving disk 42 rotates alternately clockwise and counterclockwise. The switching assembly 43 is arranged between the adjusting disk 31 and the driving disk 42, and is used to position the rotation of the adjusting disk 31 when the driving disk 42 rotates.

[0043] Reference Figure 3 and Figure 5 In another embodiment of the present application, the lifting assembly 41 includes a swing arm 411, a lifting rod 412 and two limit rods 413. The swing arm 411 is slidably penetrated in the control box 11, and one end of the swing arm 411 extending out of the control box 11 is connected to the output shaft of the drive motor 2 through the connecting assembly 44. One end of the lifting rod 412 is rotatably connected to the swing arm 411, and the other end of the lifting rod 412 is hinged to the side edge of the drive disk 42. The two limit rods 413 are welded to the inner wall of the control box 11, and the limit rod 413 is extended along the axial direction of the adjusting rod 32 and abuts against the side wall of the drive disk 42. The lifting rod 412 is located between the two limit rods 413, and the side walls of the lifting rod 412 abut against the two limit rods 413 respectively.

[0044] Through the above-mentioned arrangement, when the output shaft of the driving motor 2 rotates, the swing arm 411 is driven to slide through the control box 11 through the connecting component 44, so that the lifting rod 412 is lifted and lowered in the control box 11. Since the lifting rod 412 is hinged to the side edge of the driving disk 42 and under the limiting action of the limiting rod 413, the rotation of the driving disk 42 is realized, and the switching component 43 is used to realize the sequential conduction of the adjustment disk 31.

[0045] Reference Figure 3 and Figure 5The connecting component 44 includes a connecting column 441 and a connecting disk 442. A coupling is fixedly connected to the side wall of the connecting disk 442 by bolts, and the connecting disk 442 is coaxially fixedly connected to the output shaft of the drive motor 2 through the coupling. The connecting column 441 is fixedly connected to the side wall of the connecting disk 442 away from the drive motor 2 by bolts, and the connecting column 441 is located at the side edge of the connecting disk 442. The end of the swing arm 411 extending out of the control box 11 is rotatably connected to the connecting column 441. It should be noted that the radius of the connecting disk 442 needs to be smaller than the radius of the drive disk 42. Since the swing arm 411 is connected to the output shaft of the motor through the connecting column 441 set on the side edge of the connecting disk 442, when the output shaft of the drive motor 2 rotates, the swing arm 411 rotates circumferentially along the output shaft of the drive motor 2, and the lifting rod 412 hinged to the swing arm 411 is lifted and lowered under the limiting action of the two limit rods 413, and the lifting rod 412 is hinged to the side edge of the drive disk 42, so that the drive disk 42 rotates back and forth between clockwise and counterclockwise, and rotates the adjusting disk 31 through the switching component 43 to realize the sequential conduction of the branch cables. It should be noted that since one end of the swing arm 411 is hinged to the lifting rod 412, and the lifting rod 412 is lifted and lowered along its axial direction in the control box 11, when the swing arm 411 rotates along the output shaft of the drive motor 2, it will swing along the hinge point with the connecting rod, and a swing groove 443 for the swing arm 411 to swing needs to be provided on the surface of the control box 11.

[0046] Reference Figure 5 、 Figure 6 as well as Figure 7In another embodiment of the present application, in order to facilitate the adjustment of the adjustment disk 31 by rotating the output shaft of the motor to switch the conductive branch cable, the switching assembly 43 includes a ratchet 431, a pawl 432 and a limit spring 433. The ratchet 431 is fixedly connected to the side of the adjustment disk 31 facing the driving disk 42 by bolts, and the number of ratchet teeth of the ratchet 431 corresponds to the number of each branch cable in the control box 11. A fixed shaft 434 is welded on the side wall of the driving disk 42 facing the adjusting disk 31. One end of the pawl 432 is rotatably sleeved on the fixed shaft 434, and the other end of the pawl 432 abuts against any ratchet tooth of the ratchet 431, and is engaged when the driving disk 42 faces the adjusting disk 31. The side wall of the side is fixedly connected with a fixing block 435 by bolts, and a fixing groove is opened on the side wall of the fixing block 435 facing the pawl 432. One end of the limit spring 433 is fixedly connected to the inner wall of the fixing groove, and the other end of the limit spring 433 abuts against the pawl 432. The side wall of the driving disk 42 facing the adjusting disk 31 is fixedly connected with a limit baffle by bolts, and the limit baffle is located on the side of the pawl 432 away from the limit spring 433 and abuts against the side wall of the pawl 432. When the driving disk 42 rotates, one end of the pawl 432 abuts against the ratchet 431. Under the limit of the limit baffle, the pawl 432 drives the ratchet 431 to rotate the adjusting disk 31.

[0047] A positioning assembly 45 for positioning the adjustment disk 31 is provided on the side wall of the adjustment disk 31 facing the driving disk 42. The positioning assembly 45 includes a fixing ring 451, a plurality of protrusions 452, a telescopic spring 453 and a plurality of limit blocks 454. The fixing ring 451 is fixedly connected to the side wall of the adjustment disk 31 facing the driving disk 42 by bolts, and the fixing ring 451 is circumferentially arranged around the ratchet 431. A plurality of protrusions 452 are welded to the inner wall of the fixing ring 451, and the position and number of the protrusions 452 and the ratchet 431 are corresponding. The protrusions 452 are arranged to protrude in an arc shape toward the ratchet 431, and the ratchet 431 faces the protrusions 453. A limiting groove is provided at the end of the side wall on one side of 52, and a telescopic spring 453 is arranged in the limiting groove, and one end of the telescopic spring 453 is fixedly connected to the inner wall of the limiting groove, and one end of the limiting block 454 extends into the limiting groove and is fixedly connected to the telescopic spring 453, and the end of the limiting block 454 facing away from the telescopic spring 453 extends out of the limiting groove and abuts against the arc-shaped convex surface of the protrusion 452. In order to facilitate the rotation of the adjusting disk 31, the end of the limiting block 454 slides on the arc-shaped convex surface of the protrusion 452, and the end of the limiting block 454 extending out of the limiting groove is spherical. In the initial state, the end of the limiting block 454 abuts against the lowest point of the arc-shaped surface of the protrusion 452.

[0048] Through the above arrangement, the output shaft of the drive motor 2 rotates and drives the lifting rod 412 to rise and fall. Since the lifting rod 412 is rotationally connected to the driving disk 42, the driving disk 42 continuously rotates clockwise and counterclockwise. When the driving disk 42 rotates clockwise / counterclockwise, the pawl 432 abuts against the ratchet 431, thereby driving the rotation of the adjusting disk 31. When the driving disk 42 rotates in the opposite direction (i.e., counterclockwise / clockwise) under the drive of the lifting rod 412, the limit spring 433 abutting against the side wall of the pawl 432 contracts. When the pawl 432 is re-located to the end of the adjacent ratchet tooth, the limit spring 433 extends, so that the pawl 432 abuts against the end of the ratchet tooth, so that when the output shaft of the drive motor 2 rotates, the adjusting disk 31 can be rotated.

[0049] In order to avoid errors in the data collected by the current sensor due to the conductive sheet 35 not being in the groove 34 of the adjacent connecting block 33 due to the driving disk 42 rotating too little, in the initial state, the end of the limit block 454 abuts against the lowest point of the arc-shaped surface of the protrusion 452, and when the ratchet 431 rotates, the limit block 454 is squeezed by the arc-shaped surface of the protrusion 452, so that the limit block 454 is gradually pushed into the limit groove. As the adjusting disk 31 rotates driven by the driving disk 42, when the end of the limit block 454 moves to the highest point of the arc-shaped surface, the telescopic spring 453 gradually stretches, and the end of the limit block 454 abuts against the protrusion 452, pushing the adjusting disk 31 to rotate.

[0050] The implementation principle of this embodiment is as follows: different monitoring areas of the laboratory building are divided, and corresponding power supply plans are matched according to the functional types of the monitoring areas. The power supply plan is changed according to the real-time electrical parameter usage data in the monitoring area obtained by the electrical parameter detection unit 1, so as to achieve the purpose of improving the monitoring effect of the monitoring system.

[0051] The process of the electrical parameter detection unit 1 obtaining the electrical parameters in the target area is achieved by controlling the rotation of the output shaft of the drive motor 2. Since the output shaft of the drive motor 2 is connected to the swing arm 411 in a non-coaxial manner, when the output shaft of the drive motor 2 rotates, the lifting rod 412 is lifted and lowered under the limit of the limit rod 413. Since the rotation connection point between the lifting rod 412 and the drive disk 42 is located at the edge of the side wall of the drive disk 42, one lifting and lowering of the lifting rod 412 (that is, one rotation of the output shaft of the drive motor 2) drives the drive disk 42 to rotate back and forth slightly between clockwise and counterclockwise, so that the pawl 432 abuts against the ratchet on the side wall of the adjustment disk 31 and drives the adjustment disk 31 to rotate. By setting the number of ratchets corresponding to the number of branches in the control box 11, when the adjustment disk 31 rotates, the conductive sheet 35 can conduct each branch cable in turn to facilitate detection by the current sensor B213 (in the initial state, the conductive sheet 35 conducts any branch).

[0052] At the same time, in order to prevent the conductive sheet 35 from not being in the groove 34 of the connecting block 33 due to the driving disc 42 driving the adjusting disc 31 to rotate too small, thereby affecting the recording of electrical parameters, a protrusion 452 corresponding to the number of ratchet teeth is provided on the periphery of the ratchet 431, and the protrusion 452 is arranged to protrude in an arc shape toward the ratchet teeth. In the initial state, the limit block 454 on the side wall of the ratchet is located at the lowest point of the arc surface of the protrusion 452. When the driving disc 42 drives the adjusting disc 31 to rotate, the limit block 454 gradually slides toward the highest point of the arc surface of the protrusion 452, pressing the limit block 454 into the limit groove. At this time, the telescopic spring 453 is in a contracted state. When the end of the limit block 454 slides over the highest point of the arc surface of the protrusion 452, the telescopic spring 453 gradually expands, causing the limit block 454 to slide toward the lowest point of the arc surface of the protrusion 452, and driving the adjustment disk 31 to rotate. Since the number between the protrusion 452 and the ratchet teeth is the same as the number of each branch, and the branches are evenly arranged along the axis circumference of the control box 11 in the control box 11, the conductive sheet 35 can detect the electrical parameters of each branch cable in turn by rotating the output shaft of the drive motor 2, thereby improving the monitoring effect of the monitoring system.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
