Description

Technical Field

[0001] The present invention relates to the field of new energy and water treatment technology, and in particular to a prefabricated cabin-type plateau independent microgrid smart life and direct drinking water preparation system. Background Art

[0002] In recent years, with the continuous improvement of living standards, people's attention to drinking water health has increased, and water purification equipment-related products have also diversified. However, most of the existing water purification equipment on the market is concentrated in small household, medium community or factory-concentrated types. These devices are mainly aimed at families, communities and cities with suitable installation environments, good power supply systems, and developed network systems. In remote areas, especially in cold areas, due to the harsh installation environment, lack of equipment supporting industry chain, difficult repair and maintenance conditions, and limitations of power network problems, existing water purification equipment cannot effectively meet the drinking water safety needs of these areas.

[0003] Small household and medium-sized community water purification equipment cannot adapt to the harsh environment in plateau areas, and the use of the equipment is limited; while factory-based centralized water purification equipment requires a large amount of capital to build infrastructure and establish a professional operation and maintenance team for management. In the case of loose and point-distributed villages and towns in plateau areas, it cannot play its maximum role. Therefore, there is an urgent need for a water purification equipment system that can adapt to the harsh environment of the plateau, has independent power supply capabilities, is easy to maintain, and can achieve remote management.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] Embodiment 1 See also Figure 1-3 As shown, a prefabricated cabin-type plateau independent microgrid smart life and direct drinking water preparation system in this embodiment includes an insulated prefabricated cabin shell, an independent wind, solar and storage microgrid, a life and direct drinking water preparation system, a security monitoring system and a remote intelligent management system.

[0020] The domestic and direct drinking water preparation system is a two-stage purification system. The first stage uses quartz sand, activated carbon, resin and precision wedge filters to preliminarily purify the raw water to form domestic water stored in the intermediate water tank; the second stage uses a high-pressure pump to transport the domestic water in the intermediate water tank to the RO membrane and other membrane groups to purify the domestic water to form direct drinking water stored in the direct drinking water tank.

[0022] All electrical parts of the system have been corrected for high altitude, fully considering the impact of the special natural environmental conditions in high altitude areas on the performance of electrical equipment. Through technical means and rigorous testing and verification, the stable operation and reliability of the electrical parts in the extreme 6,000-meter high altitude environment are ensured.

[0023] The working process of the prefabricated cabin-type plateau independent microgrid smart life and direct drinking water preparation system is as follows: System construction and installation: First, the profile frame, external galvanized panels and internal linings are assembled into an insulated prefabricated cabin shell, and polyurethane insulation material is filled between the panels and the linings to ensure good thermal insulation performance.

[0024] A cable interlayer is reserved on the top of the shell, and a water pipe interlayer and an equipment installation interface are reserved on the bottom to facilitate subsequent equipment transportation, installation, and laying of lines and waterways.

[0025] Independent microgrid power supply: Power is supplied by photovoltaic panels and wind turbines, and photovoltaic and wind turbine controllers are responsible for power generation control to ensure effective collection of electrical energy.

[0026] The colloid battery stores electrical energy, and the inverter converts the stored electrical energy into the voltage type and level required by the system, forming an independent microgrid and providing stable and reliable electricity for the entire system.

[0027] Preparation of living and drinking water: In the primary purification stage, the raw water is initially purified by quartz sand, activated carbon, resin and precision wedge filters to form domestic water and store it in the intermediate water tank.

[0028] In the secondary purification stage, the high-pressure pump transports the domestic water in the intermediate water tank to the RO membrane and other membrane groups for purification, forming direct drinking water and storing it in the direct drinking water tank.

[0029] The water purification system is equipped with high-precision sensors such as conductivity, water level, and pressure at key locations at all levels to collect system information and implement precise water production control strategies through PLC.

[0030] Security monitoring and remote management: The security monitoring system consists of access control equipment, fire-fighting equipment, video surveillance equipment, 4G network and other equipment to achieve real-time monitoring of the operation process inside and outside the system.

[0031] The remote intelligent management system relies on the 4G network and combines with the intelligent gateway to upload the system operation data to the cloud platform, build a system operation visualization interface through the cloud platform, and realize remote management and control of the entire system equipment.

[0032] Beneficial effects: Adapting to the harsh plateau environment: The system uses a heat-insulating prefabricated cabin shell with good heat-insulating properties, capable of withstanding the severe cold climate in plateau areas.

[0033] All electrical parts have been corrected for high altitude, ensuring stable operation and reliability in extreme 6,000-meter high-altitude environments, solving the problem of limited equipment use in plateau areas.

[0034] With independent power supply capability: Power supply is achieved through independent wind, solar and storage microgrids, without relying on external power grids, solving the limitations of power grid networking in plateau areas.

[0035] The gel battery stores electrical energy, and the inverter converts electrical energy to form an independent microgrid, which provides stable and reliable electricity for the entire system and ensures the continuous operation of the system.

[0036] Easy to maintain: The system design takes into account the requirements of easy transportation, installation and maintenance. Equipment installation interfaces and water pipe interlayers are reserved at the bottom of the prefabricated cabin shell to facilitate equipment replacement and maintenance.

[0037] The remote intelligent management system realizes remote management and control of system equipment, reducing the frequency and difficulty of on-site maintenance.

[0038] Meeting the need for safe drinking water: The domestic and direct drinking water preparation system adopts a two-stage purification process to ensure that the water quality meets the direct drinking standards and meets the healthy drinking water needs of people in the plateau areas.

[0039] The water purification system is equipped with high-precision sensors at key locations at all levels, and precise water production control strategies are implemented through PLC, ensuring the stability and reliability of water quality.

[0040] To sum up: it effectively solves the problem of difficult to meet the demand for safe drinking water in plateau areas, and has broad application prospects and practical value.

[0041] There are 8 intelligent control PLC program blocks, namely the main program block (OB1), initialization program block (SBR0), water production program block (SBR1), power system program block (SBR2), analog program block (SBR3), alarm program block (SBR4), communication program block (SBR5), and environmental control program block (SBR7). In the alarm program block, in order to prevent frequent false alarms and improve the accuracy of alarm detection, the hysteresis alarm is set in the program. The hysteresis alarm flow chart is as follows Figure 2 shown.

[0042] Embodiment 2 See also Figure 1-3 As shown, a prefabricated cabin-type plateau independent microgrid smart life and direct drinking water preparation system of this embodiment, the insulated prefabricated cabin shell also includes lighting equipment, ultraviolet disinfection equipment, environmental sensing equipment and auxiliary equipment. The lighting equipment can be manually controlled individually, or it can be automatically controlled according to the cabin door opening and closing status, cabin brightness or time period to save energy. The ultraviolet disinfection equipment is automatically controlled according to time, and supports modification of the cycle and disinfection duration. At the same time, it detects the situation in the cabin before starting disinfection. When there are people moving, it delays opening and locks the cabin door after opening to prevent harm to personnel. The environmental sensing device senses the cabin environment through temperature and humidity sensors and water leakage sensors, and forms a control strategy through the PLC algorithm to control auxiliary equipment such as heating equipment, fans, and contactors, so that the cabin environment is in dynamic balance, ensuring safe and reliable operation of the equipment.

[0043] The basic workflow of multi-sensor data fusion is that the sensor first measures the object to be measured, collects the original monitoring data, and converts the analog signal input by the sensor into a digital signal A / D. Then the collected raw data is subjected to data preprocessing, data noise filtering and final data screening. Finally, the data fusion decision is made through a pre-set rule algorithm to obtain the output result of the system for the object to be measured. The multi-sensor fusion methods can be mainly classified into three types: distributed, centralized and hybrid. Among them, the hybrid fusion method has strong adaptability and stability, combines the advantages of centralized and distributed fusion, and has a broad application prospect, such as Figure 3 Shown is a hybrid sensor distribution structure.

[0044] The control system is designed based on PLC technology and consists of three parts: status monitoring, control and execution. First, the status monitoring part is located at the forefront of the system, and is mainly responsible for real-time acquisition and transmission of device operation data. The PLC connects various sensors through the PROFINETIO bus. The sensors convert parameters such as water quality and pressure into 4~20 mA standard analog signals, which are collected by the analog input module of the PLC. The collected data such as raw water quality, purified water quality, intermediate water tank level, product water tank level, pressure before and after the membrane, etc., are used as input conditions for the control part after multi-sensor data fusion processing by the PLC.

[0045] The control part receives the input conditions given by the status monitoring part, analyzes them, and generates control instructions by comparing the set standard parameters with the control logic. The execution part then issues the control instructions.

[0046] The execution part is located at the output end of the system, responsible for converting the instructions issued by the control part into physical operations, directly acting on the water treatment equipment. The workflow of the execution part begins with receiving the control instructions. The instructions mainly contain two types of information: one is the on-off state of the relay, which is used to control the start and stop of equipment such as valves and pumps; the other is the value of the analog quantity, which is used to adjust continuous variables such as valve opening and pump speed. For relay output, a control method combining inching and latching is adopted, which can be manually controlled and prevent interlocking. For analog output, digital-to-analog conversion and linearization processing are required. The execution part adjusts the operating status of valves, pumps and backwashing devices according to the instructions to ensure that the water quality meets the standards. During the whole process, the operation results of the execution part will be fed back to the control part to achieve closed-loop control and ensure efficient and stable operation of the system.

[0047] Embodiment 3 See also Figure 1-3As shown, a prefabricated cabin-type plateau independent microgrid smart life and direct drinking water preparation system of this embodiment is difficult to transport due to the inconvenient transportation in plateau areas and the difficulty in transporting large equipment. Therefore, the present invention adopts a modular design concept to modularize the insulation type prefabricated cabin shell according to demand. When the water production volume requirement is large, the volume of the entire system will exceed the transportation limit. At this time, it can be reasonably divided according to the water production volume to form a plurality of independent water production modules. Each water production module forms a water production sub-cabin body in its own system. After the modules are transported to the site, they are connected through the reserved pipe interface and the electrical interface to complete the cabin assembly. This modular design not only facilitates transportation and installation, but also improves the flexibility and scalability of the system.

[0048] In addition, this embodiment also expands the communication function of the independent wind, solar and energy storage microgrid. Specifically, the photovoltaic and wind turbine controllers and inverter devices are equipped with 485 communication interfaces and support the general Modbus-RTU communication protocol. Through this function, the remote management and control of the independent microgrid can be realized, which is convenient for operation and maintenance personnel to perform remote monitoring and maintenance. At the same time, this function also provides a basis for the intelligent management of the system.

[0049] The raw water pump adopts a multi-modal interlocking control strategy based on PLC, and achieves precise control through the intermediate water tank level transmitter. The mathematical formula of the control strategy is as follows:

[0050] in, It is the control result, indicating the state of the raw water pump, 1 means start, 0 means stop; Real-time liquid level of the intermediate water tank; Set the stop level of the raw water pump in the intermediate water tank (90%-95% of the effective volume is recommended); Set the starting liquid level of the raw water pump in the intermediate water tank (recommended to be 20%-25% of the effective volume).

[0051] According to the formula, the meaning of the control strategy formula can be obtained. When the real-time liquid level of the intermediate water tank Lower than the starting liquid level setting value of the raw water pump in the intermediate water tank hour, , PLC outputs the start command through the DO module; when the real-time liquid level of the intermediate water tank Reach the stop setting value of the raw water pump in the intermediate water tank hour, , PLC executes the raw water pump shutdown procedure.

[0052] The high-pressure pump adopts a dual-liquid-level collaborative control strategy based on PLC. The high-pressure pump control is realized through the collaborative triggering of the liquid levels of the intermediate water tank and the product water tank. The operation of the high-pressure pump must meet the dual-variable condition judgment algorithm. The control equation is as follows:

[0053] in, It is the control result, indicating the state of the high-pressure pump, 1 means start, 0 means stop; Real-time liquid level of the intermediate water tank; Real-time liquid level of product water tank; Set the stop level of the high-pressure pump in the intermediate water tank (90%-95% of the effective volume is recommended); Set the starting level of the intermediate tank high-pressure pump (recommended to be 20%-25% of the effective volume); Set the stop level of the high-pressure pump in the product water tank (90%-95% of the effective volume is recommended); Set the starting level of the high-pressure pump in the product tank (20%-25% of the effective volume is recommended).

[0054] According to the formula, the meaning of the high-pressure pump control equation can be obtained. When the real-time liquid level of the product water tank Lower than the starting level setting of the high pressure pump in the product water tank , and the real-time liquid level of the intermediate water tank Higher than the setting value of the start-up liquid level of the high-pressure pump in the intermediate water tank hour, , PLC controls the high-pressure pump to start. If any of the two conditions is not met, the high-pressure pump cannot start; when the real-time liquid level of the product water tank Higher than the starting level setting of the high pressure pump in the product water tank , or real-time liquid level of intermediate water tank Lower than the setting value of the start-up liquid level of the high-pressure pump in the intermediate water tank hour, , PLC controls the high-pressure pump to stop.

[0055] The water delivery pump adopts a PLC-based mode selection strategy. The strategy logic is divided into enabling logic and control logic. The logic equation is as follows:

[0056] in, It is the control result, indicating the status of the water pump, 1 means start, 0 means stop; It is the real-time status of card control; The real-time status of the emergency button; Indicates the system mode, the sales mode is 0 and the emergency mode is 1; Indicates the real-time liquid level status of the product water tank. It is 1 when the real-time liquid level is greater than the water pump start level setting value, otherwise it is 0.

[0057] The enabling logic is that when the liquid level in the product tank is higher than the starting liquid level setting value of the product tank water pump, the real-time liquid level status of the product tank =1, PLC allows the water pump to start. When the liquid level in the product water tank is lower than the set value for stopping the water pump in the product water tank, the real-time liquid level status of the product water tank =0, PLC prohibits the water pump from starting. The water pump control logic is further divided into sales mode ( =0) and emergency mode ( =1), in the sales mode, water can only be taken on site through the card control device. After swiping the card, the card control device sends a control signal. At this time, the real-time status of the card control =1, when =1 and satisfy both, =1, PLC receives and controls the water pump to start, and the card control device starts charging. After swiping the card again, the card control real-time status =0, then =0, the PLC program stops the water pump and ends the timed charging; the emergency mode is designed for emergency rescue scenarios and needs to be switched through the cloud platform. It cannot be switched locally. After the cloud platform sends a switching signal, the on-site PLC controls the emergency button to enable. At this time, the system mode =1, the water pump can be controlled by the card at the same time ( ) and the emergency button ( ) controls the start of water delivery, and the control logic is consistent with that in the sales mode, meeting the water demand in emergency rescue scenarios.

[0058] Lighting equipment, ultraviolet disinfection equipment, environmental sensing equipment and auxiliary equipment are installed in the shell of the thermal insulation prefabricated cabin. The lighting equipment can be automatically controlled according to the door opening and closing status, cabin brightness or time period; the ultraviolet disinfection equipment is automatically controlled according to time, and detects the cabin situation before opening, delays opening when there are people, and locks the cabin door after opening; the environmental sensing equipment senses the cabin environment through temperature and humidity sensors and water leakage sensors, and forms a control strategy through the PLC algorithm to control auxiliary equipment such as heating equipment, fans, and contactors.

[0059] The intelligent temperature control in the station monitors the ambient temperature in the station in real time, and automatically starts heating when a low temperature environment occurs, ensuring that the ambient temperature in the station is not lower than the set temperature, ensuring that the equipment and pipelines in the station are not frozen, and improving the stability of safe operation. The controller collects the ambient temperature in the station and performs intelligent control. The automatic air adjustment in the station is achieved by setting an air conditioning fan in the station. Because the station is a closed environment and is generally closed for a long time, a low oxygen and toxic environment may occur when the station is closed for a long time. When maintenance personnel enter, they may suffer from hypoxia or poisoning and fainting, posing a risk to life safety. The automatic air adjustment device in the station can start the air conditioning fan while opening the door, quickly completing the internal and external circulation of the air in the station, and ensuring the personal safety of maintenance personnel entering the station.
