The housing 11 includes a water inlet 111 and a water outlet 112.
The filter assembly 12 is disposed within the housing 11 and includes a primary filter layer 121, the primary filter layer 121 being located at a portion of the filter assembly 12 that water first contacts when entering the housing 11 through the water inlet 111.
The device-side communication unit 24 is used for data communication between the respective components of the filtering device 1 and with the portable terminal 2, and the device-side control unit 25 stores a computer program for controlling the operations of the respective components of the filtering device 1.
A pumping mechanism 13 is disposed within the housing 11 for pumping aquarium water from the inlet into the housing, through the filter assembly 12 and out the outlet 112 into the aquarium.
The backflush mechanism 14 is used to backflush the filter assembly 12.
The odor detection part 15 is an odor recognition chip fixed to the primary filter layer 121 of the filter assembly 12 through a waterproof case, and detects the odor of the water entering the filter device.
The odor detection section 15 has an odor detection unit 15a and an odor value generation unit 15b. The odor detection unit 15a is configured to detect the odor near the odor detection unit 15, that is, the odor of the water near the water outlet 112, as a current odor, and the odor value generation unit 15b generates a corresponding current odor value according to the current odor. The current odor value is a unique combination of values representing the current odor.
In the present embodiment, the odor detection unit 15a includes at least one first gas sensor and at least one second gas sensor. The first gas sensor is responsive to at least one of alcohol gas, ammonia/amine gas, alkane gas, olefin gas, aldehyde gas, CO gas, sulfur-containing gas, acid gas, and ketone gas, and generates a first response signal according to the detected odor.

In this embodiment, the initial odor value and the threshold odor change rate in the initial odor value storage unit 16 and the threshold odor change rate storage unit 17 may be set by themselves. Specifically, the device-side communication unit 24 of the present embodiment is connected to the mobile terminal 2 in a communication manner, and the user performs setting via the mobile terminal 2.
Fig. 4 is a block diagram of a mobile terminal according to an embodiment of the present invention.
In this embodiment, the mobile terminal 2 is a smart phone. As shown in fig. 4, the portable terminal 2 includes a screen storage unit 26, an input display unit 27, a portable communication unit 28, and a portable control unit 29.
The mobile-side communication unit 28 is used for data communication between the respective components of the mobile terminal 2 and with the filtering apparatus 1, and the mobile-side control unit 29 stores a computer program for controlling the operations of the respective components of the mobile terminal 2.
The screen storage unit 26 stores an odor initial information setting screen 261, a reminder screen 262, and an odor information check screen 263.
When the initial value of the smell and the threshold value of the smell change rate need to be set, the input display unit 27 displays a smell initial information setting screen 261 for allowing the user to input and confirm the threshold value of the smell change rate. Once the user confirms the input odor change rate threshold, the mobile-side communication unit 28 transmits the odor change rate threshold input by the user to the apparatus-side communication unit 24.
When the apparatus-side communication unit 24 receives the odor change rate threshold value input by the user, the odor detection unit 15 detects the current odor and generates a current odor value, the odor initial value storage unit 16 stores the current odor value as an odor initial value, and the odor change rate threshold value storage unit 17 stores the received odor change rate threshold value.
The filtration rate storage unit 18 stores a first filtration rate and a second filtration rate, wherein the first filtration rate is greater than the second filtration rate.
The recoil interval time storage section 19 stores a predetermined time.
When the user turns on the filter device 1, the device-side control section 25 controls the water pumping mechanism 13 to pump water at the first filtration rate and filter.
The odor detection part 15 continuously detects the current odor of the water passing through the filtering apparatus 1 and generates a current odor value according to the current odor.
The odor change rate calculation section 20 calculates an odor change rate from the initial odor value and the current odor value. Specifically, the odor change rate calculation section 20 calculates an odor change value, which is a difference between the current odor value and the initial odor value, from the current odor value and the initial odor value, and calculates an odor change rate, which is a percentage of the odor change value to the initial odor value and is expressed as a percentage.
The comparison and judgment section 21 judges whether the odor change rate calculated by the odor change rate calculation section 20 is greater than the odor change rate threshold stored in the odor change rate threshold storage section 17, and if so, the apparatus-side control section 25 controls the water pumping mechanism 13 to increase the first filtration rate to the second filtration rate for pumping water.
Meanwhile, if the comparison and determination part 21 determines that the odor change rate is greater than the odor change rate threshold, the alarm part 22 issues an alarm for reminding the user of the water in the aquarium. In this embodiment, the alarm unit 22 is an indicator lamp that blinks when an alarm is issued.
Meanwhile, when the comparison determination unit 21 determines that the odor change rate is larger than the odor change rate threshold, the device-side communication unit 24 transmits the determination result and the odor change rate to the mobile-side communication unit 28, and when the mobile-side communication unit 29 receives the determination result and the odor change rate, the input display unit 27 displays a warning screen 262 and displays information for warning the user of replacement of the water in the aquarium and the odor change rate on the screen.
When the pumping mechanism 12 increases the pumping rate, i.e., the filtering rate, from the first filtering rate to the second filtering rate, and after the predetermined time stored in the backflushing interval time storage unit 19, the comparison and judgment unit 21 judges whether the odor change rate obtained from the current odor value is still greater than the odor change rate threshold, and if so, the apparatus-side control unit 25 controls the backflushing mechanism 14 to be turned on and perform backflushing cleaning.
The odor information storage unit 23 stores the current odor value, the odor change rate, and the determination result as the odor information at regular intervals, and stores the odor information at intervals of ten minutes in the present embodiment, in association with the current time.
When the user needs to view the information in the smell information storage section 23, the input display section 27 of the mobile terminal 2 displays a smell information viewing screen 263 and displays the smell information in the smell information storage section 23 in the screen, which is represented by a smell change rate-time graph in the present embodiment.
FIG. 5 is a flow chart of the operation of the safety farming system according to an embodiment of the present invention.
The following describes the work flow of the safe cultivation system 100 in this embodiment with reference to fig. 5, which specifically includes the following steps:
step S1, a user starts the filtering device 1 to enable the water pumping mechanism 13 to pump water at a first filtering speed, and then the step S2 is carried out;
step S2, the odor detection unit 15a in the odor detection section 15 detects the current odor of the water passing through the filtering apparatus 1, and then proceeds to step S3;

step S4, the odor change rate calculating part 20 calculates the odor change rate according to the received current odor value and the initial odor value, and then the step S5 is carried out;
step S5, the comparison and judgment part 21 judges whether the calculated odor change rate is larger than an odor change rate threshold value, if so, the step S6 is then carried out, and if not, the step S2 is carried out again;
in step S6, the alarm section 22 issues an alarm, and the apparatus-side control section 25 controls the pumping mechanism 13 to increase the pumping rate from the first filtration rate to the second filtration rate, and then the process proceeds to step S7.
In this embodiment, when the comparison determination unit 21 determines that the calculated odor change rate is greater than the odor change rate threshold, the device-side communication unit 24 simultaneously transmits the determination result and the odor change rate to the mobile-side communication unit 28, and the input display unit 27 displays a warning screen 262 and displays information for warning the user to replace the water in the aquarium and the odor change rate on the screen.
Step S7, after a preset time, the comparison judgment part 21 judges whether the calculated odor change rate is larger than an odor change rate threshold value, if so, the step S8 is entered, and if not, the step S is entered into an ending state;
