Problems solved by technology

[0003] When there are multiple sensors managed by one server device, and when the number of measurements and data transmissions in the sensor increases, the data stored and analyzed by the server device increases, the server device cannot finish processing, or the processing capacity of the server device decreases
[0004] In addition, as the measurement and data transmission in the sensor increases, the power consumption will of course also increase.
For example, when the sensor is operated with a battery, the life of the battery will be shortened as the number of measurements and data transmission increases, requiring frequent replacement of the battery
On the other hand, when the number of measurements is reduced, it may not be possible to perform appropriate control of equipment

Embodiment approach ）

[0034] Such as figure 1 As shown, the sensor management system 100 of this embodiment includes a sensor device 1 and a server device 2 for managing the sensor device 1 , and they communicate with each other. This communication may use a wireless line or a wired line. Alternatively, the function of the server device 2 may also be integrated in the sensor device 1 . In addition, in this embodiment, a case where one sensor device 1 communicates with the server device 2 has been described, however, the number of sensor devices 1 communicating with the server device 2 is not limited to one.

[0035] The sensor device 1 has: a power supply unit 11, a sensor unit 12, a sensor control unit (sensor control unit) 13, a sensor communication unit 14, a measurement data storage unit 15, an operation setting parameter storage unit (variation storage unit) 16, an input unit 17.

[0036] The power supply unit 11 is a driving source of the sensor device 1, and is a replaceable battery in th...

Embodiment ）

[0072] Next, examples and comparative examples in the case where the sensor device according to the present embodiment is used to measure the temperature (room temperature) in a greenhouse and control the opening and closing of windows of the greenhouse will be described as specific examples. These are merely examples, and use of the sensor device of this embodiment is not limited to these.

[0073] In the greenhouse, the temperature is measured by the sensor device, and the opening and closing of the windows are controlled so that the temperature does not exceed 40°C and does not fall below 25°C. In the following comparative examples and Examples 1 to 4, sensor devices having the same configuration are used, and only different configurations will be described. All sensor units operate on power from the battery.

Embodiment 1）

[0079] In the sensor device of Embodiment 1, the difference between the current measurement value and the threshold value is calculated, and the minimum arrival time to the threshold value is calculated based on the difference and the maximum change amount, and the shortest time interval between the minimum arrival time and the measurable time interval by the sensor device is calculated. (1 minute), the time of the larger one is determined for the next measurement time.

[0080] Figure 7 It is a graph showing measured values ​​from 9:30 to 13:30 when the sensor device of Example 1 was used. The upper limit of the control threshold is 35°C and the lower limit is 30°C, and the windows are controlled to be opened when the measured value exceeds 35°C, and the windows of the greenhouse are controlled to be closed when the measured value is lower than 30°C. The control thresholds of 30° C. and 35° C. are determined based on user experience. It can be seen that the farther away fr...

Abstract

This sensor device (1) is provided with: a difference calculation unit (1311) that calculates the difference between a predetermined threshold and a current measured value measured by a sensor unit (12) that measures a measurement subject; an operation-setting-parameter recording unit (16) that records the maximum amount of change of the measured value with respect to elapsed time on the basis of a plurality of measured value history records; a minimum time calculation unit (1312) that calculates the minimum arrival time that is the minimum time for the measurement subject to arrive at the predetermined threshold from the current measured value on the basis of the calculated difference and the maximum amount of change; a measurement time determination unit (132) that determines the time of the next measurement of the measurement subject from whichever time is the greater of the minimum arrival time and the minimum time interval at which the sensor device (1) can measure; and a sensor control unit (13) that controls the sensor unit (12) in a manner so as to measure the measurement subject at the determined time.

Description

technical field [0001] The present invention relates to a sensor device that measures a measurement target, a management system including the sensor device and a server device that manages the sensor device, and the like. Background technique [0002] In our surrounding environment, various sensors are installed, and the measurement data obtained by the sensors are collected and analyzed by the server device (or the main device). Then, the devices installed in the surrounding environment are controlled using the analysis result. [0003] When there are multiple sensors managed by one server device, and when the number of measurements and data transmissions in the sensors increases, the data stored and analyzed by the server device increases, and the server device cannot finish processing, or the processing capacity of the server device decreases. [0004] In addition, as the measurement and data transmission in the sensor increases, the power consumption will of course also...
