Description

[Technical field]

[0001] The present invention relates to a monitoring system for monitoring the air-conditioning state of an air-conditioned room. [Background technology]

[0002] Accurate control of indoor air conditioning is required in places such as air-conditioned mushroom cultivation and clean rooms in semiconductor factories. However, it was difficult to tell at a glance whether the indoor temperature was higher or lower than the set temperature. Conventionally, there has been disclosed an air conditioning control device that displays temperature information on a screen using colors based on color information associated with the temperature information in order to make it easier to understand the temperature display (see, for example, Patent Document 1).

[0003] [Patent Document 1] JP 2013-164212 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the air conditioning management device described in Patent Document 1 requires the user to constantly keep an eye on the temperature monitoring screen, which makes it impossible to perform other tasks, resulting in poor work efficiency. In addition, the air conditioning management device described in Patent Document 1 requires the user to set up a new management device or replace the meter, which increases the introduction cost.

[0005] This invention was developed with such problems in mind, and aims to provide a monitoring system that can efficiently monitor air conditioning status while performing other tasks, and can reduce installation costs by using conventional meters as they are. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the monitoring system of the present invention is a monitoring system that monitors a meter which shows the air conditioning status of an air-conditioned room as a numerical value on a display unit, and is characterized in having a network camera that intermittently or continuously photographs the meter, a read range setting means that sets a read range including the display unit from the image photographed by the network camera, a numerical data storage means that reads and stores the numerical value from the read range set by the read range setting means, a threshold input means for inputting a predetermined threshold value for the air conditioning status, a threshold storage means that stores the threshold value input to the threshold input means, a monitoring means that transmits an exceedance signal when the numerical value stored in the numerical data storage means exceeds the threshold value stored in the threshold storage means, and a notification means that notifies of exceedance information when the exceedance signal is received from the monitoring means.

[0007] The monitoring system according to the present invention uses a network camera to capture images of the meter intermittently or continuously, sets a reading range including the display from the captured image, and notifies the user when the air conditioning status value in the reading range exceeds a predetermined threshold value for the air conditioning status. This eliminates the need to constantly keep an eye on the meter, and allows the user to efficiently monitor the air conditioning status while performing other tasks. Furthermore, the cost of implementation can be reduced by using the existing meter as is. The air conditioning state may be, for example, temperature, humidity, cleanliness, air pressure, air flow, etc. The threshold may be both an upper limit value and a lower limit value, or only one of them. The notification means may be, for example, a mobile phone or a smartphone that transmits an alarm to a supervisor, or an alarm device that issues an alarm to the surroundings.

[0008] The monitoring system according to the present invention is a monitoring system for monitoring a temperature meter whose temperature display unit indicates the temperature of an air-conditioned room and a humidity meter whose humidity display unit indicates the humidity of the air-conditioned room, and includes a network camera which intermittently or continuously photographs the temperature meter and the humidity meter, a temperature reading range setting means which sets a temperature reading range including the temperature display unit from an image photographed by the network camera, a temperature data storage means which reads and stores the temperature from the temperature reading range set by the temperature reading range setting means, a humidity reading range setting means which sets a humidity reading range including the humidity display unit from an image of the humidity meter photographed by the network camera, a humidity data storage means which reads and stores the humidity from the humidity reading range set by the humidity reading range setting means, and a predetermined temperature of the air-conditioned room. a humidity threshold input means for inputting a predetermined humidity threshold for the air-conditioned room; a temperature threshold storage means for storing the temperature threshold inputted to the temperature threshold input means; a humidity threshold storage means for storing the humidity threshold inputted to the humidity threshold input means; a temperature monitoring means for transmitting an excess temperature signal when the temperature stored in the temperature data storage means exceeds the temperature threshold stored in the temperature threshold storage means; a humidity monitoring means for transmitting an excess humidity signal when the humidity stored in the humidity data storage means exceeds the humidity threshold stored in the humidity threshold storage means; a temperature notification means for notifying excess temperature information when the temperature exceedance signal is received from the temperature monitoring means; and a humidity notification means for notifying excess humidity information when the humidity exceedance signal is received from the humidity monitoring means.

[0009] The monitoring system of the present invention can intermittently or continuously photograph the temperature meter and humidity meter using a network camera, and notify excess information when the temperature in the temperature reading range including the temperature display unit and the humidity in the humidity reading range including the humidity display unit exceed a predetermined threshold. Effect of the Invention

[0010] According to the present invention, it is possible to provide a monitoring system that allows users to efficiently monitor the air conditioning status while performing other tasks, and that can reduce installation costs by using conventional meters as they are. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a monitoring system according to an embodiment of the present invention. As shown in FIG. 1, the monitoring system according to the embodiment of the present invention is a system for monitoring a temperature meter 2 that displays the temperature of an air-conditioned room 1 on a temperature display section 2a and a humidity meter 3 that displays the humidity of the air-conditioned room 1 on a humidity display section 3a. Examples of air-conditioned rooms include a culture room in a mycelium factory and a clean room in a semiconductor manufacturing factory. As shown in FIG. 2, the temperature meter 2 and the humidity meter 3 are installed on the front of a control panel 4. The temperature and humidity of the temperature meter 2 and the humidity meter 3 are displayed electronically by seven segments. The control panel 4 may have a meter that displays the air-conditioned state of the air-conditioned room 1, such as cleanliness, air pressure, and air flow, as well as temperature and humidity, as numerical values ​​on the display section.

[0013] The monitoring system has a network camera 11, a temperature reading range setting means 12, a humidity reading range setting means 13, a reading range input means 14, a temperature data storage means 15, a humidity data storage means 16, a temperature threshold input means 17, a humidity threshold input means 18, a temperature threshold storage means 19, a humidity threshold storage means 20, a temperature monitoring means 21, a humidity monitoring means 22, a temperature notification means 23 and a humidity notification means 24.

[0014] The network camera 11 intermittently or continuously captures the temperature meter 2 and humidity meter 3. The temperature reading range setting means 12 sets a temperature reading range including the temperature display section 2a from the digital image captured by the network camera 11. The humidity reading range setting means 13 sets a humidity reading range including the humidity display section 3a from the digital image captured by the network camera 11. The reading range input means 14 is made up of a mouse for inputting the temperature reading range to the temperature reading range setting means 12 and the humidity reading range to the humidity reading range setting means 13. The temperature reading range and humidity reading range can be input by enclosing them in a rectangular frame. The temperature reading range setting means 12 and humidity reading range setting means 13 may be made up of a function for automatically setting the temperature reading range and humidity reading range.

[0015] The temperature data storage means 15 and the humidity data storage means 16 are composed of a hard disk memory or a flash memory linked to a computer CPU. The temperature data storage means 15 reads the temperature from the temperature reading range set by the temperature reading range setting means 12, converts it into data, and stores it. The humidity data storage means 16 reads the humidity from the humidity reading range set by the humidity reading range setting means 13, converts it into data, and stores it.

[0016] The temperature threshold input means 17 and the humidity threshold input means 18 consist of a keyboard connected to the CPU. The temperature threshold input means 17 is a means for inputting a predetermined temperature threshold for the air-conditioned room 1. The temperature threshold consists of an upper temperature limit and a lower temperature limit. The humidity threshold input means 18 is a means for inputting a predetermined humidity threshold for the air-conditioned room 1. The humidity threshold consists of an upper humidity limit and a lower humidity limit. The temperature threshold storage means 19 and the humidity threshold storage means 20 consist of a hard disk memory or a flash memory linked to the computer's CPU. The temperature threshold storage means 19 stores the temperature threshold inputted to the temperature threshold input means 17. The humidity threshold storage means 20 stores the humidity threshold inputted to the humidity threshold input means 18.

[0017] The temperature monitoring means 21 and the humidity monitoring means 22 are comprised of functions of a computer's CPU. The temperature monitoring means 21 transmits an excess temperature signal when the temperature stored in the temperature data storage means 15 exceeds the temperature threshold stored in the temperature threshold storage means 19. The humidity monitoring means 22 transmits an excess humidity signal when the humidity stored in the humidity data storage means 16 exceeds the humidity threshold stored in the humidity threshold storage means 20. The temperature notification means 23 and the humidity notification means 24 are comprised of transmission means connectable to an Internet line. When the temperature notification means 23 receives an excess temperature signal from the temperature monitoring means 21, it notifies the smartphone of a preset monitor of the excess temperature information and a notification message by email. When the humidity notification means 24 receives an excess humidity signal from the humidity monitoring means 22, it notifies the smartphone of a preset monitor of the excess humidity information and a notification message by email.

[0018] The email can include the set temperature threshold or humidity threshold and the set message. The message can be in multiple languages. In addition, the email can be used to access a detailed error screen. The site dashboard can display the error history. The temperature stored in the temperature data storage means 15 and the humidity stored in the humidity data storage means 16 can also be displayed in graphs.

[0019] Next, the processing procedure of the monitoring system according to the embodiment of the present invention will be described with reference to Fig. 3. As shown in Fig. 3, first, a digital image is read by the network camera 11 (step 31). Next, a temperature reading range including the temperature display unit 2a is set from the read digital image (step 32), and a humidity reading range including the humidity display unit 3a is set (step 33). The temperature is read from the set temperature reading range, converted into data, and stored (step 34). Also, the humidity is read from the set humidity reading range, converted into data, and stored (step 35).

[0020] It is determined whether the stored temperature exceeds the temperature threshold stored in the temperature threshold storage means 19 (step 36), and if it is determined that the temperature exceeds the temperature threshold, the monitor's smartphone is notified of the temperature exceedance information (step 37). It is also determined whether the stored humidity exceeds the humidity threshold stored in the humidity threshold storage means 20 (step 38), and if it is determined that the humidity exceeds the humidity threshold, the monitor's smartphone is notified of the humidity exceedance information (step 39). When notifying the user, the predicted cause of the temperature or humidity exceedance is described based on the experience and knowledge of the facility consultant. In addition, the contact information of a vendor who can solve the error and who enters and leaves the air-conditioned room where the camera is installed is registered in advance, and after the notification, the contact information of the vendor is notified. This allows the error to be solved more quickly.

[0021] In this way, the monitoring system according to the embodiment of the present invention can intermittently or continuously photograph the temperature meter 2 and humidity meter 3 with the network camera 11, and notify excess information when the temperature in the temperature reading range including the temperature display unit 2a and the humidity in the humidity reading range including the humidity display unit 3a exceed a predetermined threshold. Therefore, there is no need to keep a constant eye on the temperature meter 2 and humidity meter 3, and the temperature and humidity in the air-conditioned room 1 can be efficiently monitored while performing other tasks. Also, the introduction cost can be reduced by using the conventional temperature meter 2 and humidity meter 3 as is. [Explanation of symbols]
