Description

Technical Field

[0001] This invention relates to the field of museum environment control technology, and in particular to a wireless monitoring system and method for museum environment. Background Technology

[0002] The artifacts exhibited in museums have high requirements for environmental parameters, so museums are equipped with environmental parameter monitoring systems. Traditional monitoring systems monitor environmental parameters at different locations and of different types by deploying various sensors. However, these systems operate 24 hours a day without interruption, which generally results in a short lifespan for the sensor components. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a wireless monitoring system and method for museum environment, which can overcome the shortcomings of the prior art and extend the service life of the sensor without affecting normal monitoring.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0005] A wireless monitoring system for museum environments includes,

[0006] Several temperature sensors are placed in different locations within the museum to monitor the temperature inside the museum;

[0007] Several humidity sensors are placed in different locations within the museum to monitor the humidity level.

[0008] Several smoke sensors are placed in different locations within the museum to monitor the smoke concentration.

[0009] Several carbon dioxide sensors are placed in different locations within the museum to monitor the carbon dioxide concentration within the museum.

[0010] The central controller is connected to the temperature sensor, humidity sensor, smoke sensor, and carbon dioxide sensor respectively, and is used to process the monitoring data and remotely control the temperature sensor, humidity sensor, smoke sensor, and carbon dioxide sensor.

[0011] A monitoring method for the aforementioned wireless monitoring system for museum environments includes the following steps:

[0012] A. Temperature sensor, humidity sensor, smoke sensor and carbon dioxide sensor collect corresponding monitoring data and send them to the central controller. The central controller determines the real-time environmental status in the museum based on the monitoring data.

[0013] B. The central controller selects the corresponding sensor to enter sleep mode based on the data characteristics of each type of monitoring data;

[0014] C. The central controller receives monitoring data from the temperature sensor, humidity sensor, smoke sensor, and carbon dioxide sensor again, and then uses the monitoring data to determine the real-time environmental status inside the museum.

[0015] D. The central controller adjusts the working or sleep status of the sensors based on the data characteristics of each type of monitoring data.

[0016] Preferably, in step B, the central controller selects the corresponding sensor to enter sleep mode, which includes the following steps.

[0017] B1. Group each type of sensor according to the average rate of change of historical monitoring data, and the average rate of change of historical monitoring data of each group of sensors is less than the set threshold.

[0018] B2. In each group of sensors, mark the sensors whose historical monitoring data linearity exceeds the set threshold, and select the sensors to be put into sleep mode from each group of marked sensors.

[0019] Preferably, in step B2, the step of selecting the sensor to enter sleep mode is as follows:

[0020] Randomly select a sensor to go into sleep mode, and then calculate the two-dimensional correlation between the other sensors in the same group and the sleep sensor. The two-dimensional correlation includes the sensor spacing and the monitoring data separation. The two-dimensional correlation is inversely proportional to the sensor spacing and the monitoring data separation, respectively. Select the sensor with the lowest two-dimensional correlation with the sleep sensor to go into sleep mode. The number of sleep sensors in the same group shall not exceed 30% of the total number.

[0021] Preferably, in step D, the central controller adjusts the sensor's operating or sleep state by including the following steps.

[0022] Set the correspondence between the variation range of the measured environmental parameters and the minimum number of corresponding sensors required. When the variation range of the measured environmental parameters changes, determine the number of sensors in working state according to the set correspondence. When a sensor needs to be put into sleep mode, proceed to step B2. When a sensor needs to be woken up, select the sleep sensor with the smallest average two-dimensional correlation degree with the sensors in working state for waking up.

[0023] The beneficial effects of adopting the above technical solution are as follows: by designing an automatic sleep and wake-up method for the sensor, the present invention can reduce the working time of the sensor while ensuring monitoring accuracy, thereby extending the service life of the sensor.
