Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring management, and in particular to a museum collection management system. Background Art

[0002] With the continuous development of Internet of Things technology, existing technology has been able to realize dynamic management of collections and real-time dynamic tracking and monitoring of the environment around the collections. Through the integration of sensors, data such as light, temperature and humidity, and carbon dioxide concentration in the collection storage environment are collected, and the optimal environmental parameter thresholds are set. When the environment changes, automatic alarms and related adjustment actions are automatically performed.

[0003] The control method adopted by the existing museum collection storage environment monitoring and management system is generally to take relevant actions to switch when a certain parameter in the environment is higher or lower than a certain value, such as heating or cooling when the temperature exceeds or falls below the set threshold, so as to maintain the collection in the most suitable temperature range. However, this control method ignores the impact of environmental changes on the collection. Since the adjustment of environmental parameters has a certain delay, the threshold control method cannot guarantee the stability of environmental control, which is not conducive to the storage of collections. For this reason, we propose a museum collection management system. Summary of the invention

[0004] The main purpose of the present invention is to provide a museum collection management system that can effectively solve the problems in the background technology.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The environmental data acquisition module is used to collect relevant environmental factor data affecting the storage of museum collections in real time at a fixed sampling frequency, wherein the relevant environmental factors include at least one of humidity value, temperature value, light intensity value, ultraviolet index, CO2 content, and formaldehyde content;

[0008] The environmental threshold setting module is used to set the critical range of the relevant environmental factor data suitable for collection storage. imin , imax ], where ζ imin , imax are the minimum and maximum values ​​of the i-th relevant environmental factor, respectively;

[0010] The over-threshold determination module is used to construct a first determination model, and determine whether the relevant environmental factor data exceeds the critical range according to the acquired first determination model, and when the relevant environmental factor data exceeds the critical range, generate a first warning signal and send it to the central control module, wherein the expression of the first determination model is:

[0011]

[0012] In the formula, ζ iT is the real-time data value of the i-th relevant environmental factor in the T-th sampling period. When f1(x)≠0 in the first judgment model, it is judged that the relevant environmental factor data exceeds the critical range;

[0013] The over-amplitude change determination module is used to construct a second determination model, and determine whether the change amplitude of the relevant environmental factor data exceeds the critical range of the allowable change amplitude according to the acquired second determination model, and when the change amplitude of the relevant environmental factor data exceeds the critical range, generate a second warning signal and send it to the central control module, wherein the expression of the second determination model is:

[0014]

[0015] Where n is the number of sampling times. When f2(x)>0 in the second judgment model, it is judged that the change range of the relevant environmental factor data exceeds the critical range;

[0016] The central control module generates a first warning instruction and a second warning instruction in response to the first warning signal and the second warning signal respectively;

[0017] In response to the first warning instruction, the over-threshold alarm module issues an alarm that the relevant environmental factor data exceeds a critical range;

[0018] In response to the second warning instruction, the over-amplitude change alarm module issues an alarm that the amplitude of the change of the relevant environmental factor data exceeds a critical range;

[0019] The system further includes a relevant environmental factor adjustment module, which is connected to the central control module and is used to perform adjustment actions when an alarm is issued in an overcritical range, specifically:

[0020] S01: Adjust the relevant environmental factor data to the critical range [ζ imin , imax ]Inside;

[0021] S02: Adjust the change range of relevant environmental factor data to the critical range [θ imin ,θ imax ];

[0022] The system also includes a data updating module, which is used to control the environmental data acquisition module to enter a new acquisition cycle after the relevant environmental factor adjustment module completes the adjustment action.

[0023] The present invention has the following beneficial effects:

[0027] The present invention will be further described below in conjunction with specific implementation methods, wherein the accompanying drawings are only used for exemplary descriptions and represent only schematic diagrams rather than actual drawings, and should not be understood as limiting the present invention. In order to better illustrate the specific implementation methods of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0028] Example 1

[0029] like Figure 1-2 As shown, in this embodiment, the temperature value is taken as an example for explanation:

[0030] The implementation process of the technical solution of the present invention includes the following steps:

[0031] Step 1: Use the environmental threshold setting module to set the critical range of temperature values ​​suitable for collection storage [ζ imin , imax ], where ζ imin , imax are the minimum and maximum values ​​of the i-th related environmental factor, respectively. If the optimal storage temperature of the collection is 25±1℃, then ζ imin At 24°C, imax If the temperature is 26℃, the critical range of the set temperature value is [24℃, 26℃];

[0032] Step 2: The variation amplitude setting module is used to set the critical range of the allowable variation amplitude of the temperature value suitable for the storage of the collection [θ imin ,θ imax ], where θ imin ,θ imax are the minimum and maximum values ​​of the allowable variation range of the i-th related environmental factor, respectively. In this embodiment, θ imin is 0.2℃, take θ imax 0.25℃;

[0033] Step 3: Use the environmental data collection module to collect temperature data that affects the storage of museum collections in real time at a fixed sampling frequency, and set the collection frequency to 1s / time;

[0034] Step 4: construct a first determination model through the super-threshold determination module, determine whether the temperature value exceeds the supercritical range according to the obtained first determination model, and generate a first warning signal when the temperature value exceeds the supercritical range, wherein the expression of the first determination model is:

[0035]

[0036] In the formula, ζ iT is the real-time data value of the i-th relevant environmental factor in the T-th sampling period, and when f1(x)≠0 in the first judgment model, it means that the temperature value collected at this time is not within the critical range of the temperature value suitable for the storage of the collection, and it is judged that the temperature value exceeds the critical range;

[0037] Step 5: A second determination model is constructed through the over-amplitude change determination module, and whether the change amplitude of the temperature value exceeds the critical range of the allowable change amplitude is determined according to the obtained second determination model, and when the change amplitude of the temperature value exceeds the critical range, a second warning signal is generated, wherein the expression of the second determination model is:

[0038]

[0039] In the formula, n is the number of sampling times, and the expression in the formula means that in multiple consecutive cycles, the sampled data of the temperature value is processed by standard deviation, which can accurately reflect the change trend of the temperature value in a certain period, and when f2(x)>0 in the second judgment model, it means that the change amplitude of the temperature value is large, and it is judged that the change amplitude of the temperature value exceeds the critical range;

[0040] Step 6: In response to the first warning signal and the second warning signal, the central control module generates a first warning instruction and a second warning instruction, in response to the first warning instruction, the over-threshold value alarm module issues an alarm that the temperature value exceeds the critical range, and in response to the second warning instruction, the over-amplitude change alarm module issues an alarm that the temperature value changes by an amplitude exceeding the critical range;

[0041] Step 7: When the alarm exceeds the critical range, the relevant environmental factor adjustment module performs adjustment actions, specifically:

[0042] S01: Adjust the relevant environmental factor data to the critical range [ζ imin , imax ]Inside;

[0043] S02: Adjust the change range of relevant environmental factor data to the critical range [θ imin ,θ imax ];

[0044] Step 8: After the relevant environmental factor adjustment module completes the adjustment action, the control environment data collection module enters a new collection cycle.
