[0046] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0048] Figure 1 1 is a schematic diagram of a data transmission device for a water treatment device in an embodiment of the present disclosure. The data transmission device for the water treatment device includes a Hall sensor 101 and a data acquisition module 102 .

[0049] The Hall sensor 101 is arranged at the power equipment of the water treatment equipment and is spaced apart from the power line of the power equipment by a preset distance, and is used to sense and output the electrical signal on the power line.

[0050] Specifically, the Hall sensor 101 is a magnetic field sensor made based on the Hall effect, which can determine important parameters such as the conductivity type and carrier concentration of semiconductor materials. The Hall sensor can measure current and voltage of any waveform, such as DC, AC, pulse waveform, etc., and even measure transient peaks. The preset distance is the spacing distance set between the power line of the power equipment and the Hall sensor 101. The preset distance can be 2 cm, for example. Ordinary technicians in this field can set it according to needs, and the present disclosure does not limit this. The power line refers to an electric wire that transmits a large current, and can also refer to the wire of a power electrical component, such as the connecting wire of a motor, the connecting wire of an inverter, etc. It is mainly used for industrial electrical appliances, electric motors, welding machines, machine tools, industrial fans, etc., and is characterized by a voltage of generally AC 380V, using a three-phase four-wire system or a three-phase five-wire system.

[0051] Exemplarily, the Hall sensor 101 is arranged on the power line of a power device such as a water pump of a water treatment device, and is separated from the power line of the power device such as a water pump by a certain preset distance, for example, 2 cm. It does not need to be electrically contacted with the power device being measured, such as a water pump. When current passes through the power line of the power device such as a water pump, there is a magnetic field inside the energized solenoid. The Hall sensor 101 is used to measure the size of the magnetic field generated by the power line of the power device such as a water pump when the power device such as a water pump is working, so as to further obtain the electrical signal on the power line of the power device. The electrical signal can be, for example, a voltage signal and / or a current signal when the power device is working, which is not specifically limited in the present disclosure.

[0052] It should be noted that the power equipment is the internal electrical equipment of the water treatment equipment. The power equipment may be, for example, a fan, a water pump, etc., but is not limited thereto and is not specifically limited in the present disclosure.

[0053] The data acquisition module 102 is connected to the Hall sensor 101 and is used to collect the electrical signal output by the Hall sensor 101 and transmit the electrical signal to the management platform.

[0054] Among them, the data acquisition module 102 is composed of an ADC converter and a wireless communication module. The ADC converter is an analog-to-digital converter, which is mainly used to convert continuous signals in analog form into discrete signals in digital form, so as to realize the collection of electrical signals of power equipment; the data acquisition module 102 transmits the collected electrical signals of the power equipment to the management platform through the wireless communication module.

[0055] Specifically, when the power equipment of the water treatment equipment, such as a water pump, is running, and current passes through the power line of the power equipment, such as the water pump, the Hall sensor 101 is used to sense and output the electrical signal of the power equipment, such as the water pump. The electrical signal can be, for example, a current signal and / or a voltage signal. At this time, the data acquisition module 102 collects the electrical signal, such as the current signal and / or the voltage signal, sensed and output by the Hall sensor 101 when the power equipment, such as the water pump, is working, and sends the collected electrical signal, such as the current signal and / or the voltage signal, of the power equipment, such as the water pump, to the management platform, which can be, for example, an Internet of Things platform.

[0056] The sewage treatment device provided in this embodiment includes a Hall sensor 101. The Hall sensor 101 is installed at the power equipment of the water treatment equipment and is separated from the power line of the power equipment by a preset distance. It is used to sense and output the electrical signal on the power line. A data acquisition module 102 is connected to the Hall sensor 101 and is used to collect the electrical signal output by the Hall sensor 101 and transmit the electrical signal to the management platform. Compared with the existing technology, the solution of this embodiment is to install the Hall sensor at the power equipment of the water treatment equipment and set a certain distance between it and the power line of the power equipment. This prevents direct contact between the power line of the Hall sensor and the power equipment, that is, it does not affect the power equipment being measured, avoiding damage to the equipment caused by the modification. The Hall sensor is used to sense and measure the magnetic field generated by the current passing through the power line of the power equipment, thereby sensing the electrical signal of the power equipment. The data acquisition module collects the electrical signal of the power equipment and transmits it to the management platform. There is no need to change the control program of the original water treatment equipment, which reduces the development workload of the renovation of old sewage treatment equipment to a certain extent. It is simple to implement and the overall renovation cost is low.

[0057] In this embodiment, the Hall sensor 101 includes a current Hall sensor and / or a voltage Hall sensor.

[0058] The current Hall sensor is arranged at the power equipment of the water treatment equipment and is spaced a preset distance from the power line of the power equipment, and is used to sense and output the current signal on the power line.

[0059] Specifically, the current Hall sensor refers to a sensor based on the magnetic balance Hall principle. According to the Hall effect principle, current is passed through the control current end of the Hall element, and a magnetic field with a magnetic induction intensity of B is applied in the normal direction of the plane of the Hall element. An electric potential will be generated perpendicular to the current and magnetic field direction (that is, between the Hall output ends). It is called the Hall potential, and its magnitude is proportional to the control current I. That is, the magnitude of the current in the current-carrying conductor is indirectly measured by measuring the magnitude of the Hall potential.

[0060] Exemplarily, the Hall current sensor is arranged on the power line of the power equipment of the water treatment equipment, such as a water pump, and is separated from the power line of the power equipment, such as the water pump, by a certain preset distance, such as 2 cm, and does not need to be electrically contacted with the power equipment to be measured, such as the water pump. When current passes through the power line of the power equipment, such as the water pump, a magnetic field B exists inside the energized solenoid, and the magnetic field B generates a Hall potential U in a direction perpendicular to the current and magnetic field passing through the power line. H , use the Hall current sensor to measure the Hall potential U generated by the power line of the power equipment such as the water pump when it is working H Size, according to the Hall potential U H The magnitude is proportional to the current I in the power line, thereby further sensing the current signal I on the power line of the output power device.

[0061] The voltage Hall sensor is arranged at the power equipment of the water treatment equipment and is spaced a preset distance from the power line of the power equipment, and is used to sense and output the voltage signal on the power line.

[0062] Among them, the voltage Hall sensor is an electronic sensor that utilizes the Hall effect. Based on the Hall closed-loop zero-flux principle, it can measure DC voltage, AC voltage, and voltage of mixed waveforms.

[0063] Specifically, the Hall voltage sensor is arranged on the power line of the power equipment of the water treatment equipment, such as a water pump, and is separated from the power line of the power equipment, such as a water pump, by a certain preset distance, for example, 2 cm. It does not need to be electrically contacted with the power equipment being measured, such as a water pump. When current passes through the power line of the power equipment, such as a water pump, there is a magnetic field B inside the energized solenoid. The Hall voltage sensor is used to measure when the power equipment, such as the water pump, is working at this time, and the size of the magnetic field B generated by the power line of the power equipment, such as the water pump, is detected and obtained. According to the proportional relationship between the voltage signal U and the magnetic field B, the voltage signal U on the power line of the power equipment, such as the water pump, is further sensed and output.

[0064] The data acquisition module 102 is further configured to acquire current signals and / or voltage signals outputted by the current Hall effect sensor and / or the voltage Hall effect sensor, respectively, and transmit the current signals and / or voltage signals to the management platform.

[0065] Specifically, when the power equipment of the water treatment equipment, such as a water pump, is running, and current passes through the power line of the power equipment, such as the water pump, a Hall current sensor and / or a Hall voltage sensor are used to sense and output the current signal I and / or voltage signal U of the power equipment, such as the water pump. At this time, the data acquisition module 102 collects the current signal I and / or voltage signal U sensed and output by the Hall current sensor and / or the Hall voltage sensor when the power equipment, such as the water pump, is running, and the collected current signal I and / or voltage signal U of the power equipment, such as the water pump, is sent to the management platform. The management platform can be, for example, an Internet of Things platform, but is not limited thereto, and the present disclosure does not specifically limit this. In this way, the present embodiment transmits the operating data of the water treatment equipment to the management platform in this way, without changing the control program of the original water treatment equipment, reducing the workload to a certain extent, and is simple to implement and has low overall cost.

[0066] Figure 2 2 is a schematic diagram of a data management system for water treatment equipment in an embodiment of the present disclosure. The data management system for water treatment equipment includes a management platform 202 and a data transmission device 201 .

[0067] The data transmission device 201 is the data transmission device 201 described in any of the above embodiments, and is in communication connection with the management platform 202 .

[0068] Specifically, when the management platform 202 is close to the water treatment equipment, or when there is only one water treatment equipment, the management platform 202 is communicatively connected to the data acquisition module 102 in the data transmission device 201. When the power equipment of the water treatment equipment, such as a water pump, is running, the data acquisition module 102 collects the electrical signals of the power equipment of the water treatment equipment, such as the water pump, when it is working, such as current signals and / or voltage signals, and transmits the collected electrical signals of the power equipment, such as the water pump, when it is working, such as current signals and / or voltage signals, to the management platform 202 through wireless communication such as general packet radio service (GPRS), 4G / 5G and other wireless communication technologies. The management platform 202 can be, for example, an Internet of Things management platform. The management platform 202, such as an Internet of Things management platform, receives electrical signals, such as current signals and / or voltage signals, when the power equipment, such as the water pump, is working, and performs data processing on the electrical signals, such as current signals and / or voltage signals, received by the management platform 202 when the power equipment, such as the water pump, is working.

[0069] Based on the above embodiments, in some embodiments of the present disclosure, such as Figure 3As shown, the data management system of the water treatment equipment also includes an Internet of Things gateway 301.

[0070] The Internet of Things gateway 301 is communicatively connected between the data acquisition module 102 and the management platform 202 .

[0071] The IoT gateway 301 serves as the link between the sensory network and the traditional communication network. As a gateway device, it enables protocol conversion between the sensory network and the communication network, as well as between different types of sensory networks, enabling both wide-area and local-area interconnection. Furthermore, the IoT gateway also requires device management capabilities. Through the IoT gateway, operators can manage the underlying sensory nodes, access relevant information about each node, and implement remote control.

[0072] Specifically, when the management platform 202 manages multiple water treatment equipment at the same time, an Internet of Things gateway 301 is set between the management platform 202 and the data acquisition module 102 in the data transmission device 201, that is, the Internet of Things gateway 301 is communicatively connected between the management platform 202 and the data acquisition module 102 in the data transmission device 201. When the power equipment of the water treatment equipment, such as a water pump, is running, the data acquisition module 102 collects the electrical signals of the power equipment of the water treatment equipment, such as the water pump, when it is working, such as current signals and / or voltage signals, and transmits the collected electrical signals of the power equipment, such as the water pump, when it is working, such as current signals and / or voltage signals, to the management platform 202 through the Internet of Things gateway 301. The management platform 202 can be, for example, an Internet of Things platform. The management platform 202, such as an Internet of Things platform, uses this to receive electrical signals, such as current signals and / or voltage signals, when the power equipment, such as the water pump, is working.

[0073] In this way, the scheme of this embodiment uses the data acquisition module to collect the electrical signals of the water treatment equipment, and transmits the collected electrical signals to the management platform through the Internet of Things gateway 301. In this way, it is convenient for operation and maintenance management personnel to manage multiple water treatment equipment at the same time, maintain the water treatment equipment in a timely and effective manner, and reduce the workload of maintaining operation and maintenance equipment to a certain extent. It is simple to implement and has low overall cost. At the same time, the Internet of Things gateway does not need to be electrically connected to the water treatment equipment to realize the transmission of electrical signals of the power equipment, thereby avoiding the problem of the Internet of Things gateway not being able to work normally after the water treatment equipment is powered off in actual operation.

[0074] On the basis of the above embodiments, in some embodiments of the present disclosure, the Internet of Things gateway 301 includes at least one of a wireless communication module, a fault automatic restart module, a power metering module, and a power outage processing module.

[0075] Among them, the wireless communication module is used to support text messages, voice calls, and two-way data communications.

[0076] Specifically, the wireless communication module refers to long-distance transmission communication between multiple nodes without propagation through conductors or cables. Wireless communication can be carried out using radio, wireless, etc. The wireless communication can use GPRS, 4G / 5G, etc., but is not limited to this. This disclosure does not make specific restrictions.

[0077] The fault automatic restart module is used to automatically restart the Internet of Things gateway when a fault occurs in the Internet of Things gateway 301 to ensure uninterrupted operation of the Internet of Things gateway.

[0078] The power metering module is used to determine the operating status of the power equipment based on the electrical signal, and output a fault alarm signal if the operating status is determined to be a fault state.

[0079] Specifically, the Internet of Things gateway 301 has a built-in power metering chip. When the data acquisition module 102 transmits the acquired electrical signals, such as current signals, of power equipment such as a water pump to the management platform 202, for example, the Internet of Things platform, through the Internet of Things gateway 301, the power metering chip can accurately detect whether the working status of the power equipment such as a water pump is normal at this time. If the detection determines that the power equipment such as a water pump has a fault at this time, for example, the power equipment such as the water pump is overloaded, underloaded, or other faulty equipment, a fault alarm information is output, and the fault alarm information, such as the fault information of the power equipment such as the water pump being overloaded or underloaded, is transmitted to the management platform 202.

[0080] The power failure processing module is used to output a power failure alarm signal when the Internet of Things gateway 301 is powered off, and at the same time transmit the electrical signal to the management platform 202 via wireless communication.

[0081] Specifically, when the data acquisition module 102 collects electrical signals such as current signals from power equipment such as water pumps, the electrical signals such as current signals from power equipment such as water pumps are transmitted to the management platform 202 through the Internet of Things gateway 301. At this time, if the Internet of Things gateway 301 is powered off, a power off alarm signal is output. At the same time, the wireless communication module installed in the Internet of Things gateway 301 can use wireless communication technologies such as GPRS, 4G / 5G, etc. to transmit electrical signals such as current signals from power equipment such as water pumps to the management platform 202.

[0082] In this embodiment, the data acquisition module 102 transmits the acquired electrical signals, such as current signals, of power equipment such as water pumps to the management platform 202 through the Internet of Things gateway 301. For example, when the Internet of Things platform, the Internet of Things gateway 301 determines the working status of the power equipment such as water pumps at this time based on the collected electrical signals. If it is determined that the power equipment such as water pumps fails, a fault alarm message is generated and transmitted to the management platform 202. At the same time, in the event of a power outage in the Internet of Things gateway 301, the electrical signals of power equipment such as water pumps can be transmitted to the management platform 202 through the wireless communication module, thereby ensuring that the electrical signals of the water treatment equipment can be uploaded normally, reducing the workload to a certain extent, and being simple to implement with low overall cost.

[0083] On the basis of the above embodiments, in some embodiments of the present disclosure, the wireless communication module is used to send the fault alarm signal output by the power metering module to the management platform 202 .

[0084] The management platform 202 is used to generate fault repair information based on the fault alarm signal, so as to promptly remind relevant personnel to repair the power equipment.

[0085] Specifically, when the data acquisition module uploads the electrical signal, such as the current signal, of the power equipment, such as the water pump, to the management platform 202 through the Internet of Things gateway 301, the built-in power metering module in the Internet of Things gateway 301 detects and determines that the power equipment, such as the water pump, has a fault, and generates a fault alarm signal. The fault alarm signal may include, for example, power equipment: water pump, operating time: 09:56 on October 21, 2020, working status: overload and other information, but is not limited to this, and the present disclosure is not specifically limited. The Internet of Things gateway 301 sends the fault alarm signal to the management platform 202 through the wireless communication module. The management platform 202 receives the fault alarm signal and generates fault repair information based on the received fault alarm signal and sends it to the management personnel. The management personnel receive the fault repair information so that they can repair the power equipment, such as the water pump, in a timely manner.

[0086] For example, Figure 4 As shown, the fault repair information window may include information such as power equipment: water pump, operating time 09:56 on October 21, 2020, working status: overload, etc. The operation and maintenance management personnel receive similar fault repair information windows, so as to promptly repair power equipment such as water pumps.

[0087] In this embodiment, the Internet of Things gateway 301 transmits the fault alarm signal to the management platform 202 through the wireless communication module. The management platform 202 receives the fault alarm signal, generates fault repair information based on the fault alarm signal and sends it to the management personnel. In this way, the management personnel can be reminded in time to repair the power equipment.

[0088] Based on the above embodiments, in some embodiments of the present disclosure, such as Figure 5 As shown, the data management system of the water treatment equipment further includes a mobile terminal 501 .

[0089] The mobile terminal 501 is communicatively connected to the wireless communication module of the management platform 202 and / or the Internet of Things gateway 301 .

[0090] The wireless communication module is further configured to send the fault alarm signal output by the power metering module to the mobile terminal 501 .

[0091] The mobile terminal 501 is used to generate fault repair information based on the fault alarm signal, so as to promptly remind relevant personnel to repair the power equipment.

[0092] Among them, the mobile terminal 501 can be, for example, a mobile phone, etc., but is not limited to this, and the present disclosure does not specifically limit it. Specifically, when the data acquisition module uploads the electrical signal of the power equipment such as a water pump, such as the current signal, to the mobile terminal 501 through the Internet of Things gateway 301, the built-in power metering module in the Internet of Things gateway 301 detects and determines that the power equipment such as the water pump has a fault at this time, and generates a fault alarm signal. The fault alarm signal can, for example, include information such as power equipment: water pump, operating time: 09:56 on October 21, 2020, working status: overload, etc., but is not limited to this, and the present disclosure does not specifically limit it. The Internet of Things gateway 301 sends the fault alarm signal to the mobile terminal 501 through the wireless communication module, and the mobile terminal 501 receives the fault alarm signal and generates fault repair information based on the received fault alarm signal and sends it to the management personnel. The management personnel receive the fault repair information so that they can repair the power equipment such as the water pump in a timely manner. In this way, in this embodiment, the Internet of Things gateway 301 transmits the fault alarm signal to the mobile terminal 501 through the wireless communication module. The mobile terminal 501 receives the fault alarm signal, generates fault repair information according to the fault alarm signal and sends it to the management personnel. In this way, the management personnel can be reminded in time to repair the power equipment.

[0093] On the basis of the above embodiments, in some embodiments of the present disclosure, the management platform 202 is further configured to process the electrical signal, generate an operation strategy for the water treatment equipment, and issue the operation strategy to the water treatment equipment.

[0094] Specifically, the management platform 202, such as the Internet of Things platform, receives electrical signals, such as current signals and / or voltage signals, from power equipment such as a water pump when it is working, and performs data processing on the received electrical signals, such as current signals and / or voltage signals. For example, data fitting, parameter estimation, interpolation and other data processing methods can be used, and algorithms such as fuzzy operations and edge computing can be used to generate an operation and maintenance management strategy for the water power equipment, thereby optimizing the operating parameters of the water power equipment and realizing refined operation and maintenance management of the water power equipment. On the other hand, after data processing of the electrical signals, such as current signals and / or voltage signals, of power equipment such as a water pump, combined with the management platform 202's own data knowledge base, a health prediction of the water treatment equipment, such as a safe life cycle, equipment fatigue and fault warning, is given, and the generated operation strategy for the health prediction of the water treatment equipment, such as a safe life cycle, equipment fatigue and fault warning, is issued to the water treatment equipment, thereby providing effective and reasonable operation and maintenance management for the water treatment equipment. In this way, this embodiment processes the collected electrical signals of the power equipment and generates an operation strategy to manage the water treatment equipment, which can effectively maintain the water treatment equipment to a certain extent, thereby reducing damage to the water treatment equipment.

[0095] It should be noted that although several modules or units of the device for action execution are mentioned in the above detailed description, this division is not mandatory. In fact, according to the embodiment of the present disclosure, the features and functions of two or more modules or units described above can be concretized in one module or unit. Conversely, the features and functions of one module or unit described above can be further divided into multiple modules or units for concretization. The components displayed as modules or units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of the disclosed solution. Those of ordinary skill in the art can understand and implement it without paying any creative work.

[0096] The present invention also provides a sewage treatment method, which can be implemented based on the data transmission device of the water treatment equipment in the above embodiments. Figure 6 As shown, the implementation steps of this method are as follows:

[0097] Step S601: The Hall sensor senses and outputs an electrical signal on the power line.

[0098] Step S602: The data acquisition module acquires the electrical signal output by the Hall sensor and transmits the electrical signal to the management platform.

[0099] In the above embodiment, the electrical signal on the power line is sensed and output by the Hall sensor. The data acquisition module collects the electrical signal output by the Hall sensor and transmits the electrical signal to the management platform. Compared with the prior art, the solution of this embodiment is to set a Hall sensor at the power equipment of the water treatment equipment and set a certain spacing distance between the power line of the power equipment, so that there is no direct contact between the power line of the Hall sensor power equipment, that is, it does not affect the measured power equipment, and avoids possible damage to the equipment caused by the modification. The Hall sensor is used to sense and measure the size of the magnetic field generated when the current passes through the power line of the power equipment, thereby sensing the electrical signal of the power equipment. The data acquisition module is used to collect the electrical signal of the power equipment and transmit it to the management platform. There is no need to change the control program of the original water treatment equipment, which reduces the development workload of transforming old sewage treatment equipment to a certain extent. It is simple to implement and the overall transformation cost is low.

[0100] Optionally, the Hall sensor includes a current Hall sensor and / or a voltage Hall sensor, the current Hall sensor is arranged at the power equipment of the water treatment equipment and is spaced a preset distance from the power line of the power equipment; the voltage Hall sensor is arranged at the power equipment of the water treatment equipment and is spaced a preset distance from the power line of the power equipment; the method further includes the following steps:

[0101] Step I: The current Hall sensor senses and outputs the current signal on the power line.

[0102] Step II: The voltage Hall sensor senses and outputs the voltage signal on the power line.

[0103] Step III: The data acquisition module collects the current signal and / or voltage signal output by the current Hall sensor and / or the voltage Hall sensor, and transmits the current signal and / or voltage signal to the management platform.

[0104] It should be noted that although the steps of the method disclosed herein are depicted in a particular order in the accompanying drawings, this does not require or imply that the steps must be performed in that particular order, or that all steps must be performed to achieve the desired result. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into a single step, and / or a single step may be decomposed into multiple steps. Furthermore, it is readily understood that these steps may be executed synchronously or asynchronously, for example, in multiple modules / processes / threads.

[0105] Regarding the method in the above embodiment, the specific manner in which each step performs the operation and the corresponding technical effects brought about have been described in detail in the embodiment of the device, and will not be elaborated here.

[0106] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
