Technical Field

The utility model relates to the field of environment-friendly equipment, in particular to a pre-judging system for the operation condition and odor output of a compression type garbage can of a cleaning station.

Background

The municipal refuse cleaning station is mainly used for collecting all the transported refuse, wherein the compression type dustbin is widely applied to storing general household refuse or kitchen refuse. The garbage storage process inevitably produces odor pollution, wherein hydrogen sulfide and ammonia are taken as main representatives. The urban cleaning stations are often distributed around residential areas, great troubles are caused to the life and health of residents, and the mode of utilizing ozone oxidation is an effective mode for quickly removing odor sources. However, compression-type garbage cans have specific operational characteristics, and the amount of harmful gas generated is closely related to the operational state thereof.

The compression type garbage can is divided into household garbage and kitchen garbage. During operation, for domestic garbage, an external garbage conveying worker loads the garbage in the small tricycle into the hopper, when the hopper is basically full, a cleaning station worker operates the garbage can to slowly lift the hopper, meanwhile, the operation opening of the domestic garbage can is opened, the garbage is poured into the box body after the hopper is in place, then the hopper is put down, and the operation opening of the garbage can is closed. After the garbage can is filled, the whole can body is cleaned and transported at one time. The domestic garbage is filled into a hopper, and a certain amount of odor is continuously generated during the placement period before the domestic garbage is filled into the garbage bin. When the domestic garbage is poured into the garbage can, the operation opening of the garbage can is opened at the moment, and a large amount of odor can be released. In addition, before the garbage can is fully stored, multiple batches of garbage are input in an irregular and irregular amount at irregular time, so that the amount of odor generated by opening a cover at each input is greatly different.

Compression dustbin position still can be used for placing kitchen garbage case by turns sometimes, and different with domestic waste, kitchen garbage does not collect through the hopper. The kitchen waste is placed in a standard plastic garbage can in advance, workers in a cleaning station are placed in a loading area on site, the kitchen waste is lifted to a certain height one by one through operating buttons, the garbage can is inclined after a garbage can cover plate is opened, the kitchen waste is poured into a box body, and then the empty garbage can is put down to complete one-time operation. For kitchen waste, when the garbage can ready for loading and dumping is arranged around the transferring area, a certain amount of odor is generated continuously. When the kitchen waste is poured into the garbage can, the garbage can operation opening is opened at the moment, and a large amount of odor can be released. Similar to household garbage, before the garbage can is fully stored, multiple batches of garbage are input irregularly and irregularly, and the amount of odor generated by opening a cover during each input is greatly different.

According to the common deodorization control logic, namely odor is detected by a sensor to generate, and then an ozone generator is controlled to generate ozone and the ozone is put in through a putting system, the single control mode has the defect of control lag, and the odor is dispersed into a garbage station along with the air flow before the ozone is put in. Therefore, it is very important to predict the operation condition of the dustbin. Besides, the characteristic of garbage input in batches is also very important for determining the odor generation amount of each time to be predicted as accurately as possible.

As shown in fig. 1, the embodiment of the present invention provides a pre-judging system for the working condition and odor production of a compression-type dustbin of a cleaning station, which comprises a video recognition component 10, a temperature detection component 20, an odor detection component 30, an ozone generation component 40 and a control component 50. The video recognition component 10 is arranged on the outer side of the dustbin body, and the video recognition component 10 can recognize the position of the dustbin body, the working condition of the hopper and the working condition of the loading platform; the temperature detection assembly 20 is arranged outside the dustbin body and can detect the ambient temperature around the dustbin body; the odor detection component 30 is arranged outside the throwing opening of the dustbin body and can detect the amount of odor in the surrounding environment of the dustbin body (for example, the amount of odor in the ambient air in the cleaning station); the ozone generating assembly 40 is arranged outside the input port of the dustbin body (for example, is arranged in a cleaning station) and can charge ozone with set concentration into the surrounding environment of the dustbin body; the control assembly 50 is electrically connected to the video recognition assembly 10, the temperature detection assembly 20, the odor detection assembly 30 and the ozone generating assembly 40.

Identifying the operation conditions of the dustbin body by using the video identification component 10, wherein the operation conditions comprise opening and closing of the dustbin body, time, type, quantity and the like of garbage entering the dustbin body in each batch; the number, the type and the storage time of the garbage are recorded as the basis for calculating the odor generation amount, and when the garbage can body is detected to be about to start working, the control assembly 50 controls the ozone generation assembly 40 to generate ozone in advance so as to achieve the purpose of efficiently reducing and dissipating the odor.

Specifically, the video recognition component 10 is configured with a camera and an action recognition program, and can judge the position of the dustbin body, the working condition of the hopper and the working condition of the loading platform.

The odor detection assembly 30 comprises an ammonia gas detection module 31 and a hydrogen sulfide detection module 32, the ammonia gas detection module 31 and the hydrogen sulfide detection module 32 are arranged near the periphery of the dustbin body at intervals, and the ammonia gas detection module 31 and the hydrogen sulfide detection module 32 are both electrically connected with the control assembly 50.

In this embodiment, the ammonia gas detecting module 31 is configured with an ammonia gas sensor, and the range of the ammonia gas detecting module 31 is 0-1000 ppm. The hydrogen sulfide detection module 32 is provided with a hydrogen sulfide sensor, and the range of the hydrogen sulfide detection module 32 is 0-100 ppm.

The ammonia gas detection module 31 detects the ammonia gas content in the environment; when the ozone generated by the pre-judging system is not enough to eliminate all ammonia gas, the ammonia gas detection module 31 will feed back the detection signal to the control component 50, and the control component 50 controls the ozone generation component 40 to continuously reduce the residual ammonia gas.

The hydrogen sulfide detection module 32 detects the content of hydrogen sulfide in the environment; when the ozone generated by the pre-determination system is not enough to eliminate all hydrogen sulfide, the hydrogen sulfide detection module 32 will feed back a detection signal to the control module 50, and the control module 50 controls the ozone generation module 40 to continuously eliminate the residual hydrogen sulfide.

As shown in FIG. 1, the temperature detecting assembly 20 includes a temperature sensor having a range of-30 to 70 ℃. The accuracy of the temperature sensor is + -0.3%.

The temperature detecting component 20 is used for detecting the ambient temperature, the temperature is an important basis for estimation of the odor output, and the higher the temperature is, the higher the odor output of the same garbage is, the higher the required ozone concentration is. A plurality of division point temperatures and corresponding odor productivity are set in advance according to the type and kind of garbage collected by the cleaning station. When the environmental temperature is between the temperatures of the division points, linear interpolation is carried out through the two temperatures of the nearest division points to calculate the corresponding odor yield at the moment.

Specifically, when the ozone input amount is determined, 6 division point temperatures such as 0 ℃, 10 ℃, 20 ℃, 30 ℃, 40 ℃ and 50 ℃ and the corresponding odor yield are set according to the type of garbage collected by the cleaning station. At temperatures below 0 c, ozone generating assembly 40 is not activated. Odor yields for the remaining temperatures, linear interpolation was performed using the nearest two temperature points. The type of the garbage thrown into the kitchen waste every time is calculated according to the two types of the household garbage and the kitchen waste in a distinguishing mode, the throwing amount of the household garbage takes one bucket as the minimum metering unit, and the throwing amount of the kitchen waste takes one barrel as the minimum metering unit. The system records the time length of each unit of garbage after the garbage is put into the system from the time of putting the garbage into the system to the time of opening the garbage can next time. The final system calculates the total odor production for the two dosing intervals by integrating and summing. Since all the odor output cannot be completely dissipated into the space of the cleaning station, the coefficient of 0.9 is multiplied when the ozone is calculated in the embodiment.

The pre-judging system for the operation condition and odor output of the compression type dustbin at the cleaning station further comprises a power supply assembly 60 which is electrically connected with the control assembly 50, the video recognition assembly 10, the temperature detection assembly 20, the odor detection assembly 30 and the ozone generation assembly 40. The power supply assembly 60 comprises a strong current module and a weak current module, wherein the strong current module is electrically connected with the video recognition assembly 10, the ozone generation assembly 40 and the control assembly 50; the weak current module is electrically connected with the temperature detecting assembly 20 and the odor detecting assembly 30.

In this embodiment, the strong-current module is supplied with 220V ac power, and the weak-current module is 24V, 2.5A. The control component 50 is a programmable controller, and the programmable controller is two sets of input and output modules.

The ozone generating assembly 40 is an air source ozone generator. The minimum step length set for the air source ozone generator concentration is 1%. The ozone generating component 40 is a stainless steel shell, the ozone amount is less than or equal to 20g/h, and can be externally connected with a 0-20mA regulating and controlling signal.

The throwing of each bucket of domestic garbage or each barrel of domestic garbage is mechanically controlled, namely, the opening time of each bucket of domestic garbage or each barrel of kitchen garbage is fixed. Therefore, the present embodiment adopts a method of changing the ozone dosing concentration to realize the change of the ozone dosing amount in a single time. The percentage of the maximum capacity of the equipment is set to be used for expressing, the minimum concentration is determined by the minimum output concentration of the equipment and corresponds to 4mA, the maximum concentration is determined by the maximum output concentration of the equipment and corresponds to 20mA, and the intermediate concentration is proportionally converted corresponding to the current value. The concentration is set to a minimum step size of 1%.

When the dustbin body is in non-operating condition, or according to the calculated value ozone after input, ammonia gas detection module 31 and hydrogen sulfide detection module 32 still detect the foul smell and exist, carry out the time delay according to minimum concentration this moment and continue to input until ammonia gas detection module 31 and hydrogen sulfide detection module 32 can't detect the foul smell and exist.

As shown in fig. 2, when the present embodiment is applied, after the video recognition component 10 captures that the dustbin body is in place, the control component 50 starts to start, at which time the initial amount of rubbish in the dustbin is zero, and the temperature detection component 20 starts to record.

The video recognition component 10 recognizes that the household garbage enters the hopper or the kitchen garbage can enters the vicinity of the transfer area (loading platform), and indicates that the garbage throwing work is about to start. At this time, the entry temperature is determined, and if the ambient temperature is low and odor is not generated, the ozone generating unit 40 does not operate. On the contrary, the ozone generating component 40 is started and enters a low-concentration putting mode, so that a small amount of diffused odor caused by the placement of the household garbage or the kitchen garbage is reduced.

The video recognition module 10 recognizes that the hopper is lifted or the loading platform is lifted, and the feeding ports are opened at the same time, and the control module 50 starts to feed high-concentration ozone to reduce odor emission caused by unclean in the dustbin.

After the video recognition component 10 recognizes that the feeding port is closed, the ozone generation component 40 switches to the delayed low-concentration ozone feeding mode until the odor detection component 30 no longer detects the presence of odor. Meanwhile, the system records the type and the quantity of the garbage input, and records the garbage input time, the ozone input quantity and other data.

When the video recognition component 10 recognizes the start of garbage input operation again, the high-concentration ozone input amount is calculated according to the current time, the temperature curve and the like, and then the odor is completely reduced by matching with low-concentration delayed input.

When the video recognition component 10 recognizes that the dustbin body moves away from the original position, the dustbin body is fully conveyed into a cleaning program, and the control flow is finished. The control process can be circularly started again after the garbage can body is in place next time, so that the aim of automatic control is fulfilled.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: identifying the operation conditions of the dustbin body by using the video identification component 10, wherein the operation conditions comprise opening and closing of the dustbin body, time, type, quantity and the like of garbage entering the dustbin body in each batch; the number, the type and the storage time of the garbage are recorded as the basis for calculating the odor generation amount, and when the garbage can body is detected to be about to start working, the control assembly 50 controls the ozone generation assembly 40 to generate ozone in advance so as to achieve the purpose of efficiently reducing and dissipating the odor.

The above description is only exemplary of the utility model and should not be taken as limiting the scope of the utility model, so that the utility model is intended to cover all modifications and equivalents of the embodiments, which may be included within the spirit and scope of the utility model. In addition, the technical features, the technical schemes and the technical schemes can be freely combined and used.
