Description

Technical Field

[0001] The present invention relates to the technical field of temperature and humidity control, and more specifically, to a distributed intelligent control system. Background Art

[0002] The main technical goal of preventive protection of precious cultural relics is to create a long-term "stable, clean" and safe living environment for precious cultural relics, and to slow down the deterioration and damage of cultural relics materials caused by environmental factors. A large number of studies at home and abroad have shown that environmental factors are the main cause of the deterioration and damage of museum collections, mainly including temperature and humidity, light radiation, polluted gases (including particulate matter) and harmful organisms. Among them, the fluctuation of environmental humidity and the influence of various pollutants have the most significant damage to precious cultural relics in museums.

[0003] The existing technology for controlling the temperature and humidity of the environment, such as constant temperature and humidity machines or air purification equipment, relies on the working state of the sensor equipment it carries to detect the environmental parameters in the control area. For example, the air purification equipment changes the speed of the fan based on the changes in air quality detected by its own sensor. Under this model, since the sensor equipment is connected to the control function device by wire, the distance between the sensor and the control system is generally close, or even directly built into the housing of the control device, resulting in the environmental control effect mainly reflecting the environmental state of the location of the control device. For larger control spaces, the control is uneven and inaccurate, and the preservation of cultural relics is greatly affected by temperature and humidity, resulting in the difficulty of traditional control schemes to meet the needs of environmental control when storing cultural relics.

[0004] In addition, during the temperature and humidity monitoring and control process, the air needs to be dehumidified in summer before being introduced into the museum's cultural relic storage room, and in winter, the air needs to be heated and humidified before being introduced into the museum's cultural relic storage room. In this process, due to distributed intelligent control, when the air ducts corresponding to one or several constant temperature and humidity machines near a certain monitoring point have abnormal air outlets, the overall temperature and humidity in the museum's cultural relic storage room will have little impact in a short period of time. However, correspondingly, precisely because the impact is not significant in a short period of time, the fault problem is often discovered only after a long period of time has occurred. At this time, the monitoring point has low efficiency in controlling temperature and humidity due to abnormal air outlets, resulting in a larger change in temperature and humidity than expected, which is not conducive to the preservation of cultural relics. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a distributed intelligent control system, which can implement targeted control measures according to the environmental monitoring results, actively control the cultural relics preservation environment, improve the cultural relics collection and preservation capabilities and environmental control level; open up the path between the environmental monitoring system and the environmental control equipment to achieve a stable environment for the museum, and through uninterrupted intelligent control, change the short-term periodic fluctuations of temperature and humidity caused by the frequent switching of the constant temperature and humidity unit system and the inaccurate real-time temperature and humidity feedback, so as to provide a relatively stable preservation environment for the cultural relics; in addition, through the setting of the air duct and light guide tube, the air outlet of the air duct is effectively monitored, and the influence of the abnormal air outlet of the air duct on the control efficiency of the temperature and humidity in the cultural relics storage compartment is effectively avoided, and the staff can be reminded in time to intervene in the abnormal situation, thereby greatly reducing the influence of the abnormality on the temperature and humidity change amplitude of the storage environment.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Embodiment 1:

[0040] See also Figure 1-2 A distributed intelligent control system includes an intelligent decision-making system, an intelligent control module and a distributed monitoring module. The monitoring module includes multiple constant temperature and humidity acquisition terminals installed at multiple temperature and humidity monitoring points and a constant temperature and humidity monitoring center. The constant temperature and humidity acquisition terminals are connected to the constant temperature and humidity monitoring center through a gateway. The control module includes a wireless control device and a constant temperature and humidity air-conditioning unit installed at multiple monitoring points, and the constant temperature and humidity air-conditioning unit is connected to the wireless control device by signal. Among them, technical personnel in this field can select the constant temperature and humidity acquisition terminal as a suitable model of temperature and humidity sensor according to actual needs.

[0041] During intelligent regulation, the environmental monitoring equipment, i.e. the constant temperature and humidity acquisition terminal, can conduct real-time, distributed monitoring of the cultural relics storage room, and then upload the data to the intelligent decision-making system of the cloud platform. The intelligent decision-making system compares the data with the temperature and humidity of the target environment. When a deviation occurs, it sends instructions to the environmental control equipment, i.e. the constant temperature and humidity air-conditioning unit, to enable it to conduct real-time, intelligent regulation of temperature and humidity. The environmental monitoring equipment continues to conduct real-time, distributed monitoring of the cultural relics storage room, and continuously repeats the process to make the temperature and humidity of the cultural relics storage room relatively stable.

[0042] In this scheme, environmental monitoring and control are an organic whole. Based on environmental monitoring, the cloud-based environmental data analysis, calculation and management system is the control center, and the environmental control equipment is the control means. According to the set control target, the system monitors, calculates and analyzes the environmental data, controls and feedbacks it over and over again, completing the real-time, automatic and stable environmental control function. The specific workflow is that the environmental distributed perception and analysis network in a certain area reports the real-time environmental data to the environmental management system according to the set frequency. The environmental management system performs comprehensive calculation, learning and analysis according to multiple technical factors such as the category of cultural relics in the area, the set control target, the type and number of control equipment in the area, the control stability requirements, and the analysis of the historical data curve of environmental control, and generates dynamic environmental control rules in real time. The environmental management system sends the control rules to multiple environmental control equipment in the area, and the environmental control equipment controls the environment according to the rules, including revising the control target and dynamically modifying the control power. As the center of the entire system, the environmental management system continuously corrects and sends the control rules to the environmental control equipment according to the continuously received environmental data, over and over again, to achieve timely, accurate and stable environmental control.

[0043] In addition, the intelligent decision-making system takes a weighted average of the monitoring data obtained by the temperature and humidity sensors at each monitoring point, accurately monitors the temperature and humidity fields in the cultural relics storage room, and feeds the monitoring data back to the control system to achieve precise and intelligent control of the air conditioner and ensure a stable temperature and humidity environment in the cultural relics storage room.

[0044] The air outlet of each constant temperature and humidity air conditioning unit is connected to an air duct, and the openings of the multiple air ducts away from the constant temperature and humidity air conditioning unit are respectively connected to multiple compartments in the cultural relics storage warehouse. The constant temperature and humidity air conditioning unit includes a humidification module, an intelligent control module and two dehumidification modules. The humidification module and the dehumidification module are both connected to the intelligent control module signal, and the intelligent control module is connected to the wireless control device signal;

[0045] See also Fig.10 , t rm Indicates the average indoor temperature of the room under test during the test duration. It indicates the average relative humidity of the room under test during the test duration. In summer, the air in the storage room passes through the dehumidification module of the constant temperature and humidity air conditioning unit, removes the wet load, and is then sent into the room to absorb the residual heat and humidity in the room. The constant temperature and humidity air conditioning unit automatically detects the return air temperature and humidity, controls the reheat recovery amount of the unit condenser, and is precisely controlled by electric heating to ensure the indoor constant temperature and humidity requirements. Fig.11 In winter, the air is heated and humidified by the humidification module of the constant temperature and humidity air-conditioning unit and then sent into the room to ensure the stability of indoor temperature and humidity.

[0046] It is also worth noting that Fig.10 and 11 Medium rm as well as The specific threshold value can be set according to different cultural relics. The data in the figure is only the numerical setting of the preservation environment of a certain cultural relic and is only used as an example.

[0047] The air outlet of the air conditioner uses a reward and penalty algorithm, and rewards are given when it is close to the target, so that it can be better controlled later; the greater the deviation from the target value, the greater the penalty, which will weaken this action and turn more to other actions. There are only two actions: humidification action increases the humidity in the area, and dehumidification action reduces the humidity in the area.

[0048] This scheme uses distributed monitoring data to automatically present two-dimensional plane and three-dimensional stereograms of the micro-environment field, and uses interpolation algorithms to present the environment in the control space in the form of a scalar field. The temperature and humidity of all monitoring points at a certain moment in the space are used as indicator data, and the concept of the field is formed in the form of color rendering in the spatial coordinates, and displayed macroscopically. Using this layout and calculation method, environmental data at different locations in the environment can be fed back in real time, providing location references for the storage of precious cultural relics.

[0049] The constant temperature and humidity air-conditioning unit controls the humidity in the regulated area to have a daily fluctuation range of no more than 5% RH, and the temperature to have a daily fluctuation range of 2-5°C.

[0050] Temperature and humidity monitoring points are set up around the cultural relics to ensure that the temperature and humidity values ​​fed back can truly reflect that the cultural relics environment is in a controlled state.

[0051] There are 6-7 temperature and humidity monitoring points arranged in every 100 square meters of cultural relics storage room, and a total of 38-50 temperature and humidity sensors are installed.

[0052] Specifically, the location and number of temperature and humidity measurement points should also comply with the following regulations:

[0053] Indoor area less than 16m 2 A distributed intelligent control system with one monitoring point set in the center of the indoor activity area;

[0054] Indoor area 16m2 More than 30m or less 2 A distributed intelligent control system is provided with two monitoring points, the detection area is divided into three equal parts diagonally, and the two equal parts are used as monitoring points;

[0055] Indoor area 30m 2 More than 60m or less 2 A distributed intelligent control system is set up with 3 monitoring points, the room diagonal is divided into four equal parts, and three of the points are used as measuring points;

[0056] Indoor area 60m 2 More than 100m 2 A distributed intelligent control system with 5 monitoring points, with plum blossom points on two diagonal lines;

[0057] Indoor area 100m 2 Every additional 20-50m 2 Add 1-2 monitoring points as appropriate, and the added monitoring points must be set evenly.

[0058] The average indoor temperature and humidity should be monitored continuously, and the data recording time interval should not exceed 30 minutes.

[0059] See also Figure 4 and Figure 6 In the figure, a represents a wall, b represents a laser beam, and the air duct includes a pipe body 1 and a wind measuring pipe 2 fixedly connected to the mouth of the pipe body 1. An air outlet is drilled at the lower end of the wind measuring pipe 2. An air induction light guide pipe 6 is provided at the end of the wind measuring pipe 2 away from the pipe body 1, and the air induction light guide pipe 6 is located on the side away from the air outlet of the pipe body 1. A left fixed rod 51 and a right fixed rod 52 are fixedly connected between the upper end of the air induction light guide pipe 6 and the top end of the wind measuring pipe 2. The left fixed rod 51 and the right fixed rod 52 can effectively limit the fixation of the positions of the two edge ends of the air induction light guide pipe 6, so that the position of the laser emitting end 41 in the air induction light guide pipe 6 is fixed, so that the position of the laser emitting end 41 is not easily affected by the normal air outlet at the air duct outlet and deviated, such as Figure 4 , effectively ensuring that when the air duct is discharging air normally, the laser beam generated by the laser emitting end 41 can be projected onto the laser emitting end 42, thereby lighting up the wall-mounted light strip 3, and then giving the staff a signal that the air duct is discharging air normally, such as Figure 5 When the air duct does not blow air or the air volume becomes smaller, the wall-mounted light strip 3 is difficult to be normally lit, thereby timely reminding and warning the staff, thereby effectively avoiding the situation where the efficiency and effect of environmental control in the cultural relics storage room are deteriorated due to abnormal air outlet of the air duct. The end of the wind measuring tube 2 facing the laser emitting end 42 is fixedly embedded with an outer sealing piece 7, and the outer sealing piece 7 is a hard transparent structure, so that the outer sealing piece 7 is not easy to affect the irradiation of the laser beam of the laser emitting end 41 toward the laser emitting end 42.

[0060] See also Figure 5 A laser emitting end 41 is installed in the air duct 6, a laser emitting end 42 is installed on the partition wall opposite to the end of the wind measuring tube 2, and a wall light strip 3 is installed on the top of the walls around the partition. The installation span of the wall light strip 3 is relatively large. When the air outlet of the air duct is abnormal, the change at the wall light strip 3 is obvious, so that the early warning effect is better. A main control board is also installed on the partition wall. The main control board is respectively connected with the wall light strip 3, the laser emitting end 42 and the constant temperature and humidity monitoring center signal. On the one hand, the light change can immediately serve as an early warning to the on-site staff. On the other hand, the signal can be fed back to the constant temperature and humidity monitoring center, and the staff can be given an online reminder and early warning through the constant temperature and humidity monitoring center.

[0061] When the laser receiving end 42 receives the optical signal, the signal is fed back to the main control board, and the main control board controls the wall-mounted light strip 3 to light up, otherwise the wall-mounted light strip 3 is in an off state. The air outlet conditions of the branch can be judged according to their different states, and under normal circumstances, the air duct is installed on the top. In this way, the staff can judge whether the air outlet of the air duct is normal without going to the top pipeline, which can reduce the difficulty and workload of maintenance and inspection.

[0062] See also Figure 7 The air-guiding light-guiding pipe 6 includes an air-collecting pipe 61 fixedly connected to the lower end of the air-collecting pipe 61, a light-transmitting pipe 63 fixedly connected to the right fixed rod 52, and a wind control layer 62 fixedly connected between the air-collecting pipe 61 and the light-transmitting pipe 63. An inner fixed rod 53 is fixedly connected to the top end of the air-collecting pipe 61. The laser emitting end 41 is installed on the inner fixed rod 53. A temperature and humidity sensor is also installed on the inner fixed rod 53. The temperature and humidity sensor here is connected to the main control board signal.

[0063] The air collecting pipe 61 is a trumpet-shaped curved surface structure, and the aperture of one end of the air collecting pipe 61 facing the air outlet is large, and the aperture of the other end of the air collecting pipe 61 is small, so that the air collecting pipe 61 has a wind collecting effect, which is convenient for introducing wind into the air-inducing light-guiding pipe 6. The wind control layer 62 is a flexible and sealed annular sheet structure, and the wind control layer 62 is in a relaxed collapsed state. When the wind control layer 62 is fully propped up, the air collecting pipe 61, the wind control layer 62 and the light-transmitting pipe 63 are concentrically arranged, and the center points of the laser emitting end 41, the laser emitting end 42 and the air-inducing light-guiding pipe 6 are located on the same straight line. When the air outlet is normal, as shown in FIG. Figure 8-9 The middle part of the air-guiding light guide tube 6 swells under the action of wind, making it difficult for it to block the laser beam of the laser emitting end 41, so that the wall-mounted light strip 3 is normally lit. When the air volume is small or there is no air, the wind control layer 62 is difficult to be expanded, thereby blocking the light beam, so that the laser emitting end 42 cannot receive the light signal, and the wall-mounted light strip 3 is difficult to be lit.

[0064] A plurality of evenly distributed wind-binding balls 8 are fixedly connected to the outer surface of the wind control layer 62. One of the wind-binding balls 8 located in the middle of the wind control layer 62 is an electromagnet, and a controller for controlling the on and off of the electromagnet is connected to the signal of the main control board, and the remaining plurality of wind-binding balls 8 are made of magnetic material, so that there is mutual adsorption force between the plurality of wind-binding balls 8, so that the overall folds in the middle of the wind control layer 62 are in a state of mutual aggregation. When the air output is small, it is difficult to fully open the wind control layer 62, so that the air duct can play a warning role in the early stage of the problem, and there is no need to wait until it is completely unable to output air before the wall-mounted light strip 3 is extinguished.

[0065] In addition, when the air humidity or temperature at the air outlet of the air duct is not within the preset range, the temperature and humidity sensor at the inner top rod 53 will feed back the signal to the main control board, and the main control board controls the electromagnet to be energized to make it magnetic, thereby absorbing the wind-binding ball 8 around it, causing the wind control layer 62 to gradually shrink from the middle, thereby gradually blocking the laser beam emitted by the laser emitting end 41, making it difficult for the laser receiving end 42 to receive the beam signal. At this time, the main control board controls the wall-mounted light strip 3 to turn off. Only when the air volume and temperature and humidity at the air outlet of the air duct meet the standards, can the wall-mounted light strip 3 be lit. When it is off, it can provide timely warning of abnormal air outlet in the air duct to the staff.

[0066] Targeted control measures can be implemented according to the environmental monitoring results, and the cultural relics preservation environment can be actively controlled to improve the cultural relics collection and preservation capabilities and environmental control level; the path between the environmental monitoring system and the environmental control equipment can be opened up to achieve a stable environment for the museum. Through uninterrupted intelligent control, the short-term periodic fluctuations in temperature and humidity caused by the frequent switching of the constant temperature and humidity unit system and the inaccurate real-time temperature and humidity feedback can be changed, providing a relatively stable preservation environment for the cultural relics; in addition, through the setting of the air duct 6, the air outlet of the air duct can be effectively monitored, and the influence of abnormal air outlet of the air duct on the control efficiency of the temperature and humidity in the cultural relics storage compartment can be effectively avoided, and the staff can be reminded in time to intervene in the abnormal situation, thereby greatly reducing the influence of the abnormality on the temperature and humidity change amplitude of the storage environment.

[0067] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
