[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the following will describe the technical solutions in the embodiments of the present application in a clear and complete manner. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0028] The present application provides a vacuum garbage disposal unit control system, which can be used to control the state of the vacuum garbage disposal unit, to ensure its stable, efficient and safe operation. The following will describe the specific implementation schemes through several examples or embodiments in a non-restrictive manner.

[0029] Referring to Figures 1-8 , the vacuum garbage disposal unit control system according to the present embodiment comprises:

[0030] a plurality of detection modules for collecting a plurality of operating parameters of the vacuum garbage disposal unit;

[0031] a button for obtaining user instructions;

[0032] a control module for receiving signals sent by the plurality of detection modules and the button and controlling the operating state of the controlled units; wherein the controlled units include motors, water pumps, electric valves and indicator lights;

[0033] a circuit breaker arranged in each loop for controlling the on-off of the corresponding loop based on the received control signals;

[0034] a thermal relay arranged in each loop for overload protection;

[0035] a power module for supplying power to the control system.

[0036] The circuit breaker has multiple important functions in the power system, mainly including protecting the safety of circuits and devices, ensuring personnel safety, reasonably distributing electric energy and realizing remote control, and improving the stability and reliability of the power system. Each loop in the electrical diagram has a separate circuit breaker (denoted as QF) for protection.

[0037] The circuit breaker can be controlled to open or close the circuit under the control of a corresponding control signal. The control signal can be manually triggered by a user or automatically triggered according to a detection circuit provided in the circuit, such as an overcurrent detection circuit provided in the system. When the current in the circuit exceeds a threshold value (i.e., overcurrent), a control signal is sent to the circuit breaker of the circuit to cut off the power supply of the circuit, thereby achieving overcurrent protection. It can be understood that other types of detection and protection circuits can also be included, which have similar principles to overcurrent protection and will not be described here.

[0038] In addition, the various detection modules include sensors and travel switches. The sensors include temperature, pressure, and other sensors for detecting the temperature and pressure of the unit. The travel switches are used to detect the travel of each electric valve to determine the switch state.

[0039] Further, the control module includes a PLC controller and a central processor. The PLC controller is used to receive digital signals or analog signals sent by the various detection modules and buttons, and to process and send them to the central processor. The PLC controller is also used to receive digital signals sent by the central processor and convert them into analog signals that can be recognized by the controlled units.

[0040] As shown in Figures 1-8 The PLC controller includes input points and output points. In the electrical diagram, the main function of the PLC input points is to receive various signals from external devices or the environment. Specifically, the input points (I points) of the PLC are used to receive signals from sensors, buttons, travel switches, and other external devices. These signals can be digital signals (such as on-off signals) or analog signals (such as temperature, pressure, and other continuously changing physical quantity signals). The main function of the PLC output module includes receiving digital signals from the central processor and converting them into voltage or current signals that can be received by external devices to drive devices such as motor starters, valve actuators, and other devices. The output module controls the on-off of the control coil to control the external devices.

[0041] In some embodiments, the model of the PLC controller is Siemens SR20. Of course, other similar PLC controllers can also be used, which are not limited.

[0042] In some embodiments, each circuit includes an intermediate relay and a contactor. The intermediate relay is used to control the on-off of the contactor based on the received control signal to control the power supply of the controlled units in the circuit to be turned on or off.

[0043] Referring to Figures 1-5In the electrical diagram, KA represents an intermediate relay, and KM represents a contactor. The intermediate relay (such as KA1) can also be used to control the intermediate conversion in the circuit, expand the number of contacts and contact capacity, while the contactor (such as KM) is mainly used to turn on or off the main circuit of the motor or other load, that is, to realize the power on-off control.

[0044] Specifically, the normally open contact of KA1 intermediate relay can control the power supply of the coil of KM contactor. For example, KA1-1 normally open contact is used to control the power supply of the coil of KM contactor, while the normally open main contact (such as KM1-KM3) of KM contactor is used to control the on-off of the three-phase power supply of the motor 3. This control mode makes the circuit universal, facilitating the adjustment and monitoring of the working state of the motor.

[0045] For another example, in the electrical diagram, the coil of the alternating current contactor KM4 is powered, its normally open contact is closed for self-locking, at the same time, the main contact of KM4 is closed, so that the motor M4 is powered and rotates in the forward direction. The normally closed contact of KM4 is open, cutting off the current path of KM5, ensuring that KM4 and KM5 cannot be powered at the same time. The coil of the alternating current contactor KM5 is powered, its normally open contact is closed for self-locking, at the same time, the main contact of KM5 is closed, so that the motor M4 is powered and rotates in the reverse direction. The normally closed contact of KM5 is open, cutting off the current path of KM4, ensuring that KM4 and KM5 cannot be powered at the same time.

[0046] In addition, the thermal relay is mainly used for overload protection of the asynchronous motor. In the electrical diagram, each circuit has a separate thermal relay (represented by FR) for protection.

[0047] In addition, in some embodiments, the power supply module is a 24V switching power supply, which is used to convert alternating current into stable direct current.

[0048] In the electrical diagram, the 24V switching power supply is a power supply device that converts alternating current into stable direct current, and is widely used in various electronic devices. It has the characteristics of high conversion efficiency, stable performance, small size, light weight, etc., and can provide reliable power supply for various electrical appliances. The electrical diagram shows that the power supply is used for the valve.

[0049] In the above scheme, the operation control of the vacuum garbage treatment unit is realized by collecting various operating parameters of the vacuum garbage treatment unit through various detection modules and controlling based on the control module. In addition, the overloading, overcurrent protection and remote control of the vacuum garbage treatment unit can be realized through the circuit breaker and the thermal relay, thereby ensuring the safety of the vacuum garbage treatment unit.

[0050] It can be understood that the same or similar parts in the above embodiments can be mutually referred to, and the contents not described in detail in some embodiments can be referred to the same or similar contents in other embodiments.

In addition, in the description of the present application, unless otherwise specified, "a plurality of" means at least two.
