[0002] In the chemical production process, many reactions need to be carried out at a specific temperature. The intelligent management and control system of the industrial refrigeration station can accurately control the reaction temperature to ensure product quality and production safety. For example, in chemical processes such as synthetic ammonia and oil refining, the required low-temperature environment can be stably provided through intelligent management and control of the refrigeration station to ensure the smooth progress of the reaction. At the same time, the system can monitor the operating status of the equipment in real time, detect potential faults in time, and reduce production interruptions and safety accidents caused by equipment failures. Failures in any link may have a serious impact on the entire system.

[0003] At present, industrial refrigeration stations use screw machines for refrigeration and deliver cold air to places where it is needed.

However, in actual operation, staff are required to observe the amount of water inside the water tower from time to time to ensure that water is being delivered all the time, and there will always be water inside the water tower. If it is stored for a long time, impurities will be generated. When impurities enter the pipe, it is easy to cause blockage in the pipe and affect the water output.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example

[0033] Reference Figure 1-Figure 6 The present invention provides a technical solution: an intelligent management and control system for an industrial refrigeration station, including a central controller and an anti-clogging mechanism. The central controller is used to control the overall equipment. The anti-clogging mechanism includes a filtering module, the filtering module is used to filter water and filter impurities at the bottom of the filtering module. The backwashing module is used to backwash the inside of the pipeline to remove impurities at the bottom of the filtering module. The branch module is used to branch the pipeline to ensure the normal water delivery volume. The automatic module is installed on the pipeline and the branch module, and is used to automatically control the pipeline and the branch module to open or close.

[0034] In a preferred embodiment, the central controller also includes a data acquisition module, which is used to collect data. The data acquisition module also includes a temperature sensor, a pressure sensor and a flow sensor. The temperature sensor detects temperature, the pressure sensor detects pressure, and the flow sensor detects water flow. In this system, when the screw machine is in use, it will be cooled by water, so the data acquisition module is set to monitor the water flow, water pressure and the temperature of the screw machine when it is working, and obtain data in time to facilitate the staff to understand the operating status of the system. For special monitoring, temperature sensors, pressure sensors and flow sensors are set to enable special monitoring and facilitate use.

[0035] In a preferred embodiment, the data acquisition module is connected to a PLC controller, and the PLC controller is connected to an automatic control module for automatically opening and closing the branch module. The branch module includes a water pipe, which is connected to the inside of the pipeline. The connection between the two is arranged above the filter module. The branch module in this system includes a branch pipe. By setting the branch pipe, when the inside of the pipeline is blocked, the branch pipe can be used to pump water to continuously cool the screw machine to ensure that the screw machine can be used normally. In addition, for automatic operation, a PLC controller is set. The switches on the pipeline and the branch pipe can be automatically controlled by the PLC controller. When there is no blockage in the pipeline, the branch pipe will be closed. When the pipeline is blocked, the branch pipe will be opened, and water will be pumped into the pipeline through the branch pipe for continued transportation and use, which is convenient for cooling the screw machine.

[0036] In a preferred embodiment, the central controller also includes a terminal device module and a data analysis module. The terminal device module realizes communication between various devices in the system and with the remote monitoring center, and can adopt wired or wireless communication methods. The data analysis module is used to organize and predict data, and provide users with an intuitive and convenient operation and management interface. The central controller includes a storage module, which is used to store equipment operation data, and a fault recording module is provided in the storage module. Each time a device fails, the fault code will be stored in the fault recording module. This system can adopt wired or wireless communication methods, and the data analysis module is used to organize and predict data, so as to summarize the monitored data, organize it, and display the results on the control module, providing users with an intuitive and convenient operation and management interface. In addition, a storage module is also provided in the central controller system, which is used to record the working time and operating status of the overall equipment through the storage module, and each time the equipment fails, it will also be recorded. Each time a fault occurs, a fault code will appear and the fault code will be recorded. The staff will store the successful maintenance process in the form of a record book on the storage module, so that when the equipment fails again later, there is a trace to follow, and the corresponding maintenance record can be found according to the fault code, so as to quickly solve the fault and facilitate use.

[0037] The pipeline is installed on the water suction pump, and a screw machine and a chilled water pump are arranged outside the water suction pump. The screw machine and the chilled water pump are used in conjunction with each other to transmit the cold air. The water suction pump and the screw machine are used in conjunction with each other to cool the screw machine. A compression sub-module and an evaporation sub-module are installed on the screw machine, which receive liquid refrigerant from the throttling sub-module, absorb heat through the evaporation process of the evaporation sub-process, and return the refrigerant gas to the compression sub-module to form a cold cycle. The compression sub-module is used to execute the compression sub-process in the cold cycle to compress the refrigerant gas into a high-temperature and high-pressure state.

[0038] The central controller includes a safety detection module, which includes an alarm module and a control module. The alarm module is used for equipment failure alarm and timely stopping the equipment operation. The control module is used for staff to operate buttons to restore the equipment to its initial state for safe maintenance of the equipment. When the equipment fails, the safety detection module will control the alarm module to sound an alarm, and promptly notify the staff to go for maintenance. After arriving at the equipment, the cause of the failure can be determined through the fault code, and the corresponding maintenance record can be retrieved from the storage module, so that the equipment can be quickly repaired with reference to past experience. After the maintenance is completed, the system can be reset through the control module to eliminate the alarm.

[0039] The central controller also includes an optimization control module. The optimization control module automatically adjusts the operating parameters of the refrigeration equipment according to the actual operating conditions and load requirements of the refrigeration station to achieve energy saving and consumption reduction. Since some data of the equipment is not always constant during operation, the corresponding data will change according to the operating status of the equipment, such as temperature. Therefore, an optimization control module is set up. The optimization control module can automatically adjust the corresponding data to achieve the effect of energy saving and consumption reduction.

[0040] Since the equipment is automatically operated, when it is working, only inspection personnel are needed to look after the equipment on site, and technical personnel will monitor the operation of the equipment from time to time in the background. In order to facilitate communication with on-site personnel, the terminal device module also includes a remote management module. The remote management module allows users to remotely access the system through the Internet, realize remote monitoring and management of the refrigeration station, and improve management efficiency.

[0041] Specifically, the working process or working principle of the intelligent management and control system of the industrial refrigeration station is as follows: At present, the industrial refrigeration station uses a screw machine for refrigeration and delivers the cold air to the required place. When the screw machine is working, it will generate a lot of heat, which requires cooling equipment to cool it down to ensure that the screw machine can be used normally. The existing method of cooling the screw machine is water cooling, which transports water to the screw machine to cool it. However, in actual operation, the staff is required to observe the amount of water inside the water tower from time to time to ensure that water is always being transported, and there will always be water inside the water tower. If it is stored for a long time, impurities will be generated. When impurities enter the pipe, it is easy to cause blockage in the pipe and affect the water output. Therefore, this system is designed to solve this problem.

[0042] By setting up a backwash module and a branch module, and using the backwash module and the branch module in conjunction, impurities on the filter module can be removed in time, the normal water delivery is guaranteed, and the heat dissipation effect of the screw machine is improved. The specific operation is to connect an external power supply, extract the water inside the external water tower through a water suction pump, and transport it to the inside of the screw machine for heat dissipation of the screw machine. The screw machine is working normally and generates cold air, and the cold air is transported out through the chilled water pump. The round pipe on the chilled water pump is installed in the place where cold air needs to be injected, such as a freezer, for use.

[0043] In order to ensure the normal use of the refrigeration equipment, a filter module is set inside the pipeline. The filter module can filter the water when extracting water from the external water tower to avoid sucking impurities into the water suction pump and clogging the water washing pump. When used for a long time, a large amount of impurities will accumulate at the bottom of the filter module. At this time, the water flow rate of the extracted water will be reduced, thereby reducing the heat dissipation effect of the screw machine. The flow sensor detects the reduction in water output, and the PLC controller controls the automatic control module on the branch module to open, so that the branch module is unobstructed, and the pipeline is closed at the same time. At this time, the water inside the water tower will be extracted into the pipeline through the branch module, and then transported from the inside of the pipeline to the screw machine to cool it down.

[0044] The branch module includes a branch pipe. The water inside the water tower is transported to the inside of the branch pipe. Part of the water will be absorbed into the pipe and transported out, and the other part of the water will move downward inside the pipe to backwash the filter module, clean up the impurities accumulated on the bottom of the filter module, keep the pipe unobstructed, and then control only the pipe to pump water and resume initial use.

[0045] This system is equipped with a temperature sensor to monitor the temperature generated when the screw machine is working. If the temperature reaches the set maximum temperature, an alarm will be sounded through the alarm module, and the PLC controller will be used to control the removal of impurities inside the pipeline to ensure normal water delivery and timely cooling of the screw machine to ensure normal use of the screw machine. In addition, a pressure sensor and a flow sensor are set to monitor the water pressure and water flow, and to detect the pressure inside the screw machine to avoid danger due to excessive pressure.

[0046] By setting up a terminal device module and a data analysis module, the terminal device module realizes communication between various devices within the system and with the remote monitoring center, and can adopt wired or wireless communication methods. The data analysis module is used to organize and predict the data, so as to summarize the monitored data, organize it, and display the results on the control module, providing users with an intuitive and convenient operation and management interface. In addition, a storage module is also provided in the central controller system. The storage module is used to record the working time and operating status of the entire equipment, and each time the equipment fails, it will also be recorded. Each time a failure occurs, a fault code will appear and the fault code will be recorded. The staff will store the successful maintenance process in the form of a record book on the storage module, so that when the equipment fails again in the future, there will be traces to follow and the corresponding maintenance records can be found according to the fault code, so as to quickly solve the failure and facilitate use.

[0047] This system can monitor the entire process of the equipment, such as pumping, refrigeration and transportation, by setting up a safety detection module. Problems in any link can be monitored, so the safety detection module includes an alarm module and a control module. The alarm module includes an alarm light. When the equipment fails, the alarm light will light up under the control of the safety detection module to remind the staff to come for maintenance. The control module is also set to reset the equipment. When the equipment fails, it will stop directly in a certain working state. The control module can be controlled by the working operator to reset the equipment so that the staff can repair the equipment.

[0048] The optimization control module is controlled by the central controller when the equipment is working. The optimization control module can adjust some operating parameters of the equipment to enable the equipment to operate normally, such as the setting of temperature and pressure, and the adjustment of speed. It can make fine adjustments in time according to the actual working status, and the optimization control module can automatically adjust the operating parameters to meet the use and achieve energy saving and consumption reduction.

[0049] The system is also equipped with a remote management module, which is mainly suitable for staff, and includes cameras, displays, pagers, etc. Staff can monitor the equipment through cameras in the background, observe the working status of the equipment, and call on-site staff through pagers to deal with emergencies in a timely manner and ensure the safe operation of the equipment.
