Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange station control, and specifically relates to an adjustable heat supply make-up water and exhaust gas control system for a heat exchange station. Background Art

[0002] As a crucial component in the thermal system, the heat exchange station mainly undertakes the functions of heat concentration, exchange, distribution, control, and metering. It is responsible for transmitting high-temperature hot water or steam generated by a thermal power plant or other heat sources to each user area, and transferring heat to the hot water or steam on the user side through a heat exchanger to meet the heating, hot water, and other needs of users. At the same time, the heat exchange station also has the ability to adjust parameters, distribute, control, and meter the heating medium. In the prior art, when the heat exchange station is exchanging heat, the water volume and air pressure in the heat exchange station are monitored regularly through sensors. However, the monitoring time of the sensors is basically fixed. Under the influence of some external environments, the water supply volume in the heat exchange station will change. When the water supply volume is large, when the sensors monitor within a fixed period of time, the water volume consumption in the heat exchange station may be too large, resulting in too low water volume in the heat exchange station.

[0003] When the water volume in the heat exchange station is low, a series of problems may occur. These problems not only affect the normal operation of the heat exchange station but may also have an adverse impact on the heating system. The water volume in the heat exchange station is an important medium for the heating system to transfer heat. When the water volume is low, the heat exchange efficiency will decrease significantly, resulting in weakened heating effect. Users may feel a decrease in indoor temperature and cannot meet the normal heating demand. The reduction of the water volume in the heat exchange station will lead to a decrease in system pressure. The instability of the system pressure will affect the overall operation effect of the heating system, resulting in an increase in energy consumption and operating costs. In response to this, we propose an adjustable heat supply make-up water and exhaust gas control system for a heat exchange station. Summary of the Invention

[0004] To solve the above technical problems, an adjustable heat supply make-up water and exhaust gas control system for a heat exchange station is provided, and this technical solution solves the above problems.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an adjustable heat supply make-up water and exhaust gas control system for a heat exchange station, the control system includes a monitoring module, a control module, an early warning module, a data processing module, and an automatic adjustment module;

[0006] The monitoring module is used to monitor the water pressure and air pressure in the heat exchange station and upload the monitored data.

[0007] The control module is used to control the make-up water and exhaust gas in the heat exchange station.

[0008] The early warning module performs early warning processing on the water volume and air pressure in the heat exchange station based on the data obtained by the data processing module.

[0009] The data processing module is used to process the detected data and analyze the data;

[0010] The automatic adjustment module is used to automatically adjust the monitoring time of the monitoring module according to the current weather conditions;

[0011] The control system is divided into automatic operation and manual operation, and the transformation is carried out through the automatic adjustment module.

[0012] Preferably, the monitoring module monitors based on sensors, monitors the changes in the water level and air pressure inside the heat exchange station, uploads the monitoring results to the data processing module, and compares them with the set values of the make-up water level and exhaust air pressure in the current heat exchange station. If the value monitored in real time by the monitoring module is less than the preset value of the heat exchange station, a control signal is sent to the control module for water replenishment and exhaust operations. If the value monitored in real time by the monitoring module is greater than the preset value of the heat exchange station, it indicates that the water volume and gas in the heat exchange station are at normal values, and there is no need for water replenishment and exhaust operations. The monitoring module conducts regular monitoring once per unit time to obtain the situation inside the heat exchange station to determine whether water replenishment and exhaust are required.

[0013] Preferably, the data processing module preprocesses the water level data and air pressure data obtained by the monitoring module, including missing value processing, outlier processing, and duplicate value processing of the data, and calculates and analyzes the processed water level data and air pressure data. The calculation and comparison formula for the water level is:

[0014] A = B j -B y

[0015] where A is the result value obtained by comparison, and B j is the water level value actually monitored by the monitoring module, and B y is the preset water level set value inside the heat exchange station. For the calculated A value, if A > 0, it is determined that there is no need to replenish water in the current heat exchange station. If A ≤ 0, it is determined that water replenishment is required in the current heat exchange station, and the control module is used to control water replenishment. The air pressure is calculated using the same formula. If the calculated A > 0, it is determined that exhaust is required in the current heat exchange station. If A ≤ 0, there is no need for exhaust, and it is judged whether exhaust operation is required inside the heat exchange station.

[0016] Preferably, the control module includes a control unit, an execution unit, and a communication unit. The control unit uses a PLC as the core control unit to receive the data monitored by the monitoring module and perform water replenishment and exhaust operations according to the preset control logic. The execution unit is used to receive the instructions of the control unit and perform water replenishment operations and exhaust operations. The communication unit is used to connect the data communication between the control unit and the monitoring module. When the system is in automatic operation, the heat exchange station is automatically processed based on the control module.

[0017] Preferably, when the system is in manual operation, the early warning module gives an early warning based on the data obtained by the data processing module. When it is detected that water replenishment and air exhaust are required in the heat exchange station, a signal is transmitted to the early warning module to make the early warning module give an early warning. According to the result of data analysis, it is judged whether the situation in the current heat exchange station meets the early warning conditions. The early warning condition is that water replenishment and air exhaust operations are required. If the condition is met, an early warning notice is triggered. The notice methods include in-station messages, emails, text messages, phone calls and alarms. After receiving the early warning notice, the technical staff manually performs the water replenishment operation and the air exhaust operation.

[0018] Preferably, the automatic adjustment module includes a temperature monitoring unit and a water supply demand prediction unit. The temperature monitoring unit is located outside the heat exchange station and is used to obtain the external temperature situation and transmit the obtained data to the water supply demand prediction unit. After predicting and analyzing the water supply demand of local people, according to the result, the monitoring time of the monitoring module in the heat exchange station is automatically adjusted, and the adjusted time parameter is transmitted to the control module for automatic control, so as to automatically adjust the monitoring time of the monitoring module regularly to ensure the water supply demand of people.

[0019] Preferably, the temperature monitoring unit obtains the external temperature situation data based on a temperature sensor and transmits the temperature data to the water supply demand prediction unit for standby. The water supply demand prediction unit predicts the water supply. The influencing factors of the water supply include the temperature situation, the holiday load situation and the extreme weather situation. The extreme weather includes rainy days, snowy days and typhoon factors. The temperature is inversely proportional to the water supply demand. When the external temperature is higher, the water supply demand in the heat exchange station is smaller. When the external temperature is lower, the water supply demand in the heat exchange station is larger. The relationship expression is:

[0020]

[0021] Where Y w is the relationship between the temperature and the water supply demand in the heat exchange station, k is the external temperature, and z is the water supply in the heat exchange station. Where k and z are two variables. This formula means that when k increases, z will decrease. On the contrary, when k decreases, z will increase, showing an inverse relationship.

[0022] Preferably, the holiday load situation is directly proportional to the water supply. That is, during holidays, the amount of water demanded from the heat exchange station at home by people increases. When it is not a holiday and people are at work or school, the water supply to the home heat exchange station decreases. The extreme weather situation is directly proportional to the water supply. When people encounter extreme weather, the water supply of the heat exchange station increases, and vice versa. Based on the influencing factors of the water supply obtained, a supply-demand line graph is drawn. When analyzing in combination with the line graph and predicting the water supply demand in the prediction unit, the holiday situation and weather factors within the future time are obtained. If there are no holidays and bad weather conditions within the future time period, the water supply demand in the heat exchange station is predicted according to the actual obtained external temperature situation. When the external temperature is low, it indicates an increase in demand, and the monitoring time of the monitoring module is shortened through the control module to ensure timely water supply.

[0023] Preferably, in the future when there are holiday situations, based on the drawn line graph, the water supply demand is predicted to predict the water supply demand in the heat exchange station and control the monitoring time of the monitoring module. Among them, the holiday situation is obtained based on the standard calendar, and the extreme weather is obtained based on manual input. The line graph is the benchmark for prediction and judgment.

[0024] Preferably, the air pressure monitoring and water level monitoring during exhaust are detected simultaneously. By observing the line graph, the change trend of the water replenishment parameters in the heat exchange station can be analyzed for prediction and analysis.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The water replenishment and exhaust control system proposed by the present invention can automatically control the monitoring time of the monitoring module under different external environmental influencing factors. When the water supply is large, the monitoring time of the monitoring module is shortened, avoiding the situation of low water volume in the heat exchange station. Timely water replenishment and exhaust treatment are carried out in the heat exchange station, ensuring the stability of the heating system and the efficiency of heat exchange, guaranteeing the overall operation effect of the heating system, reducing energy consumption, reducing operating costs, and bringing a better application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 is the control system framework diagram of the present invention;

[0028] Figure 2 is the temperature influence line graph of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0030] Refer to Figure 1As shown in the figure, an adjustable heat exchange station heat supply make-up water and exhaust gas control system, the control system includes a monitoring module, a control module, an early warning module, a data processing module and an automatic adjustment module;

[0031] The monitoring module is used to monitor the water pressure and air pressure in the heat exchange station and upload the monitored data;

[0032] The control module is used to control the make-up water and exhaust gas in the heat exchange station;

[0033] The early warning module performs early warning processing on the water volume and air pressure in the heat exchange station based on the data obtained by the data processing module;

[0034] The data processing module is used to process the detected data and analyze the data;

[0035] The automatic adjustment module is used to automatically adjust the monitoring time of the monitoring module according to the current weather conditions;

[0036] The control system is divided into automatic operation and manual operation, and the transformation is carried out through the automatic adjustment module.

[0037] In this application, the monitoring module monitors the water pressure and air pressure in real time to ensure that the system always operates in the optimal state, avoiding the efficiency decline caused by abnormal parameters. The automatic adjustment module automatically adjusts the monitoring frequency according to the weather conditions, reducing unnecessary resource consumption, and at the same time ensuring the data accuracy and timeliness at critical moments. The early warning module can timely detect and warn potential problems such as insufficient water volume and abnormal air pressure based on the real-time data processing results, effectively preventing the occurrence of safety accidents. The control module quickly responds to the warning signal and automatically or manually performs operations such as make-up water and exhaust gas, further ensuring the safe operation of the system. The data processing module deeply analyzes the long-term monitoring data, which helps to discover the potential failure modes of the system and provides a scientific basis for preventive maintenance.

[0038] The monitoring module monitors based on sensors, monitors the changes in the internal water level and air pressure of the heat exchange station, uploads the monitored results to the data processing module, and compares them with the set values of the make-up water level and exhaust gas pressure in the current heat exchange station. If the value monitored by the monitoring module in real time is less than the preset value of the heat exchange station, a control signal is sent to the control module for make-up water and exhaust gas operations. If the value monitored by the monitoring module in real time is greater than the preset value of the heat exchange station, it indicates that the water volume and gas in the heat exchange station are at normal values, and no make-up water and exhaust gas operations are required. The monitoring module conducts regular monitoring once per unit time to obtain the situation in the heat exchange station to determine whether make-up water and exhaust gas are needed.

[0039] This application can monitor in real time to ensure that the system can quickly detect abnormal water levels and air pressures, and take timely measures to prevent the system performance degradation or failures caused by abnormal parameters. By comparing with the set values, the system can accurately determine when water replenishment or air exhaust operations are required, thus avoiding unnecessary resource waste, reducing energy consumption and mechanical wear, lowering the operating costs. Regular monitoring and timely adjustment ensure that the water level and air pressure inside the heat exchange station always remain within an appropriate range, thereby improving the stability and reliability of the system, helping to reduce system performance fluctuations caused by parameter fluctuations, and enhancing the heating experience of users.

[0040] The data processing module preprocesses the water level data and air pressure data obtained by the monitoring module, including missing value processing, outlier processing, and duplicate value processing of the data. It performs calculation and analysis on the processed water level data and air pressure data. The calculation and comparison formula for the water level is:

[0041] A = B j -B y

[0042] Where A is the result value obtained from the comparison, and B j is the water level value actually monitored by the monitoring module, and B y is the preset water level set value inside the heat exchange station. For the calculated A value, if A > 0, it is determined that no water replenishment is required in the current heat exchange station; if A ≤ 0, it is determined that water replenishment is required in the current heat exchange station, and water replenishment is controlled through the control module. The air pressure is calculated using the same formula. If the calculated A > 0, it is determined that air exhaust is required in the current heat exchange station; if A ≤ 0, no air exhaust is required, and it is judged whether air exhaust operation is needed in the heat exchange station.

[0043] The missing value processing, outlier processing, and duplicate value processing of the data in this application ensure that the data used for analysis and control is accurate and reliable, avoiding misjudgments and control errors caused by data quality problems. By comparing the monitored data with the set values, the precise A value is calculated using the formula, and based on this, it is judged whether water replenishment or air exhaust is required. This precise control reduces unnecessary operations and improves the operating efficiency of the system. Real-time monitoring and calculation processing enable the system to promptly detect and prevent potential water level or air pressure problems. For example, timely water replenishment when the water level is too low can prevent equipment overheating or damage; timely air exhaust when the air pressure is too high can prevent safety risks caused by excessive system pressure. Timely water replenishment and air exhaust operations can keep the equipment working in the best operating state, reducing equipment wear and damage caused by abnormal parameters, thereby extending the service life of the equipment.

[0044] The control module includes a control unit, an execution unit, and a communication unit. The control unit uses a PLC as the core control unit to receive the data monitored by the monitoring module and perform water replenishment and exhaust operations according to the preset control logic. The execution unit is used to receive the instructions from the control unit and execute the water replenishment operation and the exhaust operation. The communication unit is used to connect the data communication between the control unit and the monitoring module. When the system is in automatic operation, the heat exchange station is automatically processed based on the control module.

[0045] This application uses a PLC as the core control unit, which can receive the data of the monitoring module in real time and quickly respond according to the preset control logic to execute the water replenishment or exhaust operation. This instant response ensures the stable operation of the system. The PLC can accurately process the data and precisely control the amount of water replenishment or exhaust according to the data results, avoiding over - or under - dosage situations and improving the operation efficiency of the system.

[0046] When the system is in manual operation, the warning module gives a warning based on the data obtained by the data processing module. When it is detected that water replenishment and exhaust are required in the heat exchange station, a signal is transmitted to the warning module to make it give a warning. According to the result of data analysis, it is judged whether the current situation in the heat exchange station meets the warning conditions. The warning condition is that water replenishment and exhaust operations are required. If the condition is met, a warning notice is triggered. The notification methods include in - station messages, emails, text messages, phone calls, and alarms. After receiving the warning notice, the technical staff manually perform the water replenishment operation and the exhaust operation.

[0047] Refer to Figure 2 As shown, the automatic adjustment module includes a temperature monitoring unit and a water supply demand prediction unit. The temperature monitoring unit is located outside the heat exchange station to obtain the external temperature situation and transmit the obtained data to the water supply demand prediction unit. The water supply demand of local people is predicted and analyzed. After obtaining the result of the prediction and analysis, the monitoring time of the monitoring module for the heat exchange station is automatically adjusted according to the result, and the adjusted time parameter is transmitted to the control module for automatic control, automatically adjusting the regularly monitored time of the monitoring module to ensure the water supply demand of people.

[0048] Based on the result of the water supply demand prediction, the automatic adjustment module further exerts its intelligent advantage and automatically adjusts the monitoring time of the monitoring module for various parameters inside the heat exchange station. Specifically, when it is predicted that the water supply demand is about to reach the peak, the module will appropriately increase the monitoring frequency of the monitoring module to more accurately grasp the key parameters such as the water level, air pressure, and temperature inside the heat exchange station, ensuring that the system can quickly respond and meet the water supply demand. On the contrary, during the period when the water supply demand is relatively low, the monitoring frequency can be appropriately reduced to save resources and extend the equipment life.

[0049] The temperature monitoring unit obtains the temperature data of the outside world based on the temperature sensor and transfers the temperature data to the water supply demand prediction unit for backup. The water supply demand prediction unit predicts the water supply. The influencing factors of the water supply include the temperature situation, the holiday load situation, and the extreme weather situation. The extreme weather includes rainy days, snowy days, and typhoon factors. The temperature is inversely proportional to the water supply demand. When the outside temperature is higher, the water supply demand in the heat exchange station is smaller. When the outside temperature is lower, the water supply demand in the heat exchange station is larger. The relational expression is:

[0050]

[0051] Where Y w is the relationship between the temperature and the water supply demand in the heat exchange station, k is the outside temperature, and z is the water supply volume in the heat exchange station. Where k and z are two variables. This formula indicates that when k increases, z will decrease. On the contrary, when k decreases, z will increase, showing an inverse relationship.

[0052] The holiday load situation is directly proportional to the water supply. That is, during holidays, the amount of water demanded from the heat exchange station at home increases. When it is not a holiday, people are at work or school, and the water supply volume of the home heat exchange station decreases. The extreme weather situation is directly proportional to the water supply. When people encounter extreme weather, the water supply volume of the heat exchange station increases, and vice versa. Based on the obtained influencing factors of the water supply, a supply-demand line graph is drawn and analyzed. When predicting in the water supply demand prediction unit, the holiday situation and weather factors within the future time are obtained. If there are no holidays and bad weather conditions within the future time period, the water supply demand in the heat exchange station is predicted according to the actual obtained outside temperature situation. When the outside temperature is low, it indicates that the demand increases, and the monitoring time of the monitoring module is shortened through the control module to ensure timely water supply.

[0053] In the future, when there are holiday situations, based on the drawn line graph, the water supply demand is predicted to predict the water supply demand in the heat exchange station and control the monitoring time of the monitoring module. The holiday situation is obtained based on the standard calendar, and the extreme weather is obtained based on manual input. The line graph is the benchmark for prediction and judgment.

[0054] During exhaust, the air pressure monitoring and water level monitoring are carried out simultaneously. By observing the line graph, the change trend of the heat exchange station makeup water parameters can be analyzed for prediction and analysis.

[0055] In this application, the line chart can intuitively display the trend of water supply demand changing over time, including demand fluctuations in special situations such as holidays and extreme weather. This enables the operation and maintenance personnel to clearly grasp the dynamic changes in water supply demand at a glance. Through the line chart, the operation and maintenance personnel can more accurately predict future water supply demand, thereby formulating corresponding operation and maintenance strategies in advance. Before holidays or the arrival of extreme weather, increase the monitoring frequency and water replenishment preparation to ensure stable water supply. Based on the prediction results of the line chart, human, material, and financial resources can be allocated more reasonably, increasing investment during peak demand periods and appropriately reducing it during low demand periods to achieve the optimal allocation and efficient utilization of resources. Incorporating holiday and weather factors into the prediction model can significantly improve the prediction accuracy of water supply demand. These factors have a direct and significant impact on water supply demand, and ignoring them will cause the prediction results to deviate from the actual situation.

[0056] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
