Description

Compost detection device

The present invention relates to the production of compost, and in particular to a compost detection device capable of detecting the progress of compost production.

Fertile soil must have enough decomposed organic matter (or soil humus) to provide a good cultivation environment for crops. The purpose of composting is to convert the raw organic matter into a decomposing organic matter. Here, "decomposing" does not mean that the organic matter is completely decomposed, but the degree of decomposition of the organic matter has reached a level suitable for crop growth. In general, the finished compost will be dark brown, fine, soft and elastic with a hint of earthy aroma. In the process of composting, the factors that need to be controlled are temperature, oxygen concentration, stirring time, standing time, and the like. Therefore, how to monitor these factors, thereby increasing the probability of successful composting, is a topic of concern to the skilled person in the field. However, the existing open push fertilizer is easy to fail. Especially for those who lack experience, it is difficult to judge the progress of the push fertilizer process and record the relevant information. It is often more difficult to understand the cause of the failure. Therefore, it is necessary to automatically detect the compost. The relevant information and recorded devices provide the personnel with an instant understanding of the progress and status of the push fertilizer, reminding the personnel to adjust the environmental conditions of the push fertilizer, thereby improving the success rate of composting.

The present invention proposes a compost detection device for setting compost, including a temperature sensor, a time recorder, a communication module and a control circuit. The temperature sensor is used to detect the temperature of the corresponding compost, and the time recorder is used to record the time. The control circuit is electrically coupled to the temperature sensor, the time recorder and the communication module for recording the first preset temperature, the second preset temperature, and the third preset temperature. The first preset temperature is greater than the room temperature, the second preset temperature is greater than the first preset temperature, and the third preset temperature is less than the first preset temperature. The control circuit is also configured to receive the temperature. When the temperature is greater than the first preset temperature, the temperature is used as the first recording temperature and the corresponding first recording time is recorded, and the first instant message is generated, and the communication module is transmitted. Send an instant message to the remote device. When the temperature is greater than the second preset temperature, the control circuit uses the temperature as the second recording temperature and records the corresponding second recording time, generates a second instant message, and transmits the second instant message to the remote device through the communication module. . When the temperature is lower than the third preset temperature, the control circuit uses the temperature as the third recording temperature and records the corresponding third recording time, generates a composting completion message, and transmits the composting completion message to the remote device through the communication module.

In some embodiments, the control circuit further records the preset alert time. When the time of the time recorder is greater than the preset warning time and the detected temperature is not greater than the second preset temperature, the control circuit generates a warning message and transmits the warning message to the remote device through the communication module.

In some embodiments, the control circuit is more electrically coupled to a heating module disposed in the compost. When the control circuit begins to receive temperature, a start message is generated to activate the heating module. When the control circuit generates the first instant message, A close message is generated to turn off the heating module.

In some embodiments, the control circuit further records the first preset time and the fourth preset temperature, and is electrically coupled to the agitation module disposed in the compost. When the control circuit generates the second instant message, if it is determined that the first preset time has elapsed or the temperature is less than the fourth preset temperature, a start message is generated to start the stirring module. The fourth preset temperature is less than the second preset temperature and greater than the third preset temperature.

In some embodiments, the control circuit further records a fifth preset temperature. After the control circuit starts the stirring module, if it is determined that the temperature is less than the fifth preset temperature and greater than the third preset temperature, a closing message is generated to close the stirring module.

In some embodiments, the control circuit is more electrically coupled to the oxygen sensor and the gas supply. The oxygen sensor is used to detect the oxygen value of the corresponding compost. After the control circuit generates the first instant message, if it is determined that the oxygen value is lower than the preset oxygen value, a start message is generated to activate the gas supply device.

In some embodiments, the control circuit is further electrically coupled to the humidity sensor and the humidifier, and the humidity sensor is configured to detect the humidity of the corresponding compost. When the control circuit determines that the humidity is lower than the preset humidity, a start message is generated to activate the humidifier.

In some embodiments, the compost detecting device further includes a display device electrically coupled to the control circuit. The control circuit calculates an estimated completion time based on the first recording time, and displays the estimated completion time on the display device. In some embodiments, the control circuit is based on the first recording time and the second recording time The estimated completion time is calculated and updated, and the updated estimated completion time is displayed on the display device.

The temperature sensor 210 is used to detect the temperature. When the compost detection 110 is inserted into the compost 120, the temperature sensor 210 can detect the temperature of the corresponding compost 120. The communication module 230 is electrically coupled to the remote device 130, and the communication module 230 can conform to any suitable protocol or standard. For example, the communication module 230 can be implemented as a wireless transmission module, such as a Bluetooth module or a WiFi module. The control circuit 240 is electrically coupled to the temperature sensor 210, the time recorder 220, and the communication module 230. The control circuit 240 can be implemented as a processor of any form or can be programmed. Circuit.

3 is a temperature profile depicting composting, in accordance with an embodiment. Referring to FIG. 3, the control circuit 240 records the first preset temperature T1, the second preset temperature T2, the third preset temperature T3, the fourth preset temperature T4, and the fifth preset temperature T5. The first preset temperature T1 is greater than the room temperature (about 25 degrees Celsius), the second preset temperature T2 is greater than the first preset temperature T1, and the fourth preset temperature T4 is less than the second preset temperature T2 and the fifth preset temperature. T5 is smaller than the fourth preset temperature T4, and the third preset temperature T3 is smaller than the fifth preset temperature. For example, the first preset temperature T1 is between 40 degrees Celsius and 50 degrees Celsius, the second preset temperature T2 is between 60 degrees Celsius and 80 degrees Celsius, and the fourth preset temperature T4 is between 55 degrees Celsius and 75 degrees Celsius. The fifth preset temperature T5 is about 35 degrees Celsius, and the third preset temperature T3 is close to room temperature. These temperatures are used to detect which stage the compost is made.

Please refer to FIG. 1 to FIG. 3. First, the control circuit 240 receives the temperature detected by the temperature sensor 210. When the temperature is greater than the first preset temperature T1, the control circuit 240 uses the temperature as the first recording temperature and records the corresponding first. Record the time R1. Moreover, the control circuit 240 generates a first instant message and transmits the first instant message to the remote device 130 via the communication module 230. For example, the first instant message is to inform the user that the temperature of the compost has exceeded the first preset temperature T1, at which time the activity of the microorganism has increased, and some microorganisms have begun to decompose the organic matter. In some embodiments, the compost needs to be heated to exceed the first preset temperature T1, so when the control circuit 240 begins to receive the temperature detected by the temperature sensor 210 and the temperature has not exceeded the first preset. At temperature T1, control circuit 240 A start message is generated to activate the heating module 152 for heating the compost. When the control circuit 240 generates the first instant message (ie, the first recording time R1), the control circuit 240 generates a close message to turn off the heating module 152.

After the first recording time R1, the control circuit 240 continues to receive the detected temperature and determines whether the temperature exceeds the second preset temperature T2. When the temperature is greater than the second preset temperature T2, the control circuit 240 treats the temperature as the second recording temperature and records the corresponding second recording time R2. Moreover, the control circuit 240 generates a second instant message and transmits the second instant message to the 130 remote device via the 230 communication module. For example, the second instant message is to notify the user of the temperature of composting to exceed the second preset temperature T2. In addition, in some embodiments, the control circuit 240 records a preset warning time. When the time of the time recorder 220 is greater than the preset warning time, and the detected temperature is not greater than the second preset temperature T2. The control circuit 240 generates an alert message and transmits the alert message to the remote device 130 via the communication module 230. For example, the warning message is to notify the user that the temperature of the compost has not exceeded the second preset temperature T2, indicating that the fermentation of the microorganism may be problematic, and the user can further check the condition of the compost.

The control circuit 240 further records the first preset time, which is, for example, two days to three days. After the detected temperature exceeds the second preset temperature T2, the control circuit 240 determines whether the first preset time has elapsed and/or the detected temperature is less than the fourth preset temperature T4. If it is determined that the first preset time has elapsed and/or the temperature has been less than the fourth preset temperature T4, the control circuit 240 generates a start message to activate the agitation module 142. In some real In the embodiment, the control circuit 240 can also record the fourth recording time R4 and transmit an instant message to the user to inform that the standing has been started and the compost is being stirred.

After the control circuit 240 activates the stirring module 142 at the fourth recording time R4, it is determined whether the detected temperature is less than the fifth preset temperature T5. If the detected temperature is less than the fifth preset temperature T5, the control circuit 240 generates a close message to close the agitation module 142. At this time, the control circuit 240 can also record the fifth recording time R5 and transmit an instant message to the user to inform the current status of the compost.

Next, the control circuit 240 determines whether the detected temperature is less than the third preset temperature T3. When the temperature is less than the third preset temperature T3, the control circuit 240 treats the temperature as the third recording temperature and records the corresponding third recording time R3. In addition, the control circuit 240 generates a compost completion message and transmits the compost completion message to the remote device 130 via the communication module 230. In this way, the user can know that the compost has been completed.

In some embodiments, control circuit 240 can also activate/deactivate gas supply 144. Specifically, from the first recording time R1 to the fourth recording time R4 (ie, after the control circuit 240 generates the first instant message), the oxygen sensor 150 detects the oxygen value of the corresponding compost 120 (when using different The oxygen sensor will have different measurement ranges and units, and this oxygen value will be transmitted to the control circuit 240. If control circuit 240 determines that the oxygen value is below a predetermined oxygen value (different composts and microorganisms can be set to different values), control circuit 240 generates a start message to activate gas supply 144, which provides oxygen. Give compost 120. For example, when the Figaro KE-25 oxygen sensor is used as the oxygen sensor 150, the measurement range is 0 to 100%, and the preset oxygen value may be 20%. If the control circuit 240 determines that the sensed oxygen value is lower than At 20%, the gas supply 144 will be activated to pump or increase oxygen.

On the other hand, before the second recording time R2 (before the first recording time R1), the humidity sensor 146 detects the humidity of the corresponding compost 120 and transmits the humidity to the control circuit 240. If the control circuit 240 determines that the humidity is lower than the preset humidity (a different value can be set according to different composts and microorganisms, for example, between 50% and 80%), the control circuit 240 generates a start message to activate the humidifier 146. . For example, the humidifier 146 can sprinkle water, thereby increasing the humidity of the compost 120.

In some embodiments, control circuit 240 can also predict when the compost is ripe. Specifically, the control circuit 240 may calculate an estimated completion time according to the first recording time R1, and display the estimated completion time on the display device 250. Alternatively, the estimated completion time can be communicated to the remote device 130 along with the first instant message. Further, the control circuit 240 may calculate and update the estimated completion time described above based on the first recording time R1 and the second recording time R2, and display the updated estimated completion time on the display device 250. Alternatively, the updated estimated completion time may also be transmitted to the remote device 130 along with the second instant message. In addition, the control circuit 240 may also update the estimated completion time at the fourth recording time R4 and the fifth recording time R5, respectively, and transmit the updated estimated completion time to the remote device 130. In this way, the user can grasp the progress of composting.

In some embodiments, the agitation module 142, gas supply The 144, the humidifier 146 and the heating module 152 are controlled by the user. When the control circuit 240 detects the specific condition (for example, the humidity is too low, the oxygen concentration is too low, the temperature is too low, stirring is required, etc.) The control circuit 240 can also transmit the corresponding start message and close message to the remote device 130 to let the user know that those devices need to be turned on/off. In addition, in some embodiments, a plurality of compost detecting devices 110 may be placed in different composts, and each compost detecting device 110 may transmit a message to the remote device 130, so that the user can A remote unit 130 is used to monitor the production of multiple composts.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any person skilled in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
