Description

Technical Field

[0001] This invention belongs to the field of pump station operation technology, and in particular relates to an unattended integrated automated control system for pump stations based on the Internet of Things. Background Technology

[0002] An integrated prefabricated pumping station is a type of prefabricated pumping station that integrates submersible pumps, pumping station equipment, sludge removal screen equipment, control systems, and remote monitoring systems. It features high integration, simple construction, high automation, and good performance.

[0003] Currently, integrated pumping stations are used in many situations. However, due to limitations imposed by surrounding buildings and personnel, they are mostly installed in sparsely populated sewage treatment sites. Existing integrated pumping stations are generally controlled through a dedicated control cabinet on-site. This cabinet enables the integrated pumping station to perform corresponding tasks, but requires dedicated personnel to maintain and operate it in shifts. For applications with sparse populations, this places high demands on personnel, and the working environment can be harsh. There are also integrated pumping stations that are remotely controlled, where operational information is obtained through a terminal, and corresponding operational control is performed from the terminal. However, in order to enable remote control, the integrated pumping station system is usually simplified, resulting in less comprehensive functionality. Furthermore, the instability introduced by remote control can also have a certain impact on the operational safety and stability of the integrated pumping station. Summary of the Invention

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] like Figure 1-4As shown, the IoT-based unattended integrated automated control system for pumping stations includes a PLC control cabinet 1 and a pumping station body 2. The PLC control cabinet 1 is connected to a touchscreen 3 and a communication terminal module 4. The communication terminal module 4 is connected to multiple data acquisition modules 5. The PLC control cabinet 1 is also connected to an IoT communication module 6. The IoT communication module 6 is connected to a receiving terminal 7 and a cloud platform 8. Both the receiving terminal 7 and the cloud platform 8 are connected to the PLC control cabinet 1 via the IoT communication module 6. The PLC control cabinet 1 is installed on the pumping station body 2, and the pumping station body 2 contains internal components. There is a liquid level sensor 9, which is connected to the PLC control cabinet 1. The pump station body 2 is equipped with a No. 1 pump 10 and a No. 2 pump 11. Both No. 1 pump 10 and No. 2 pump 11 are connected to the communication terminal module 4 through the data acquisition module 5. The PLC control cabinet 1 is also connected to the execution communication main module 12, and the execution communication module is connected to multiple execution communication sub-modules 13. No. 1 pump 10 and No. 2 pump 11 are connected to the PLC control cabinet 1 through the execution communication sub-modules 13 on the same side. The pump station body 2 is equipped with an upwelling speed alarm mechanism 14, which is connected to the PLC control cabinet 1.

[0024] The surge speed alarm mechanism 14 includes a fixed plate 15 fixedly installed on the upper side of the inner wall of the pump station body 2. A guide rod 16 is fixedly connected to the lower end of the fixed plate 15, and a float plate 17 is slidably connected to the wall of the guide rod 16. An inner flexible sealing sleeve 18 is fixedly connected to the upper end of the float plate 17 and the fixed plate 15. An outer flexible sealing sleeve 19 is sleeved on the outside of the inner flexible sealing sleeve 18, and the outer flexible sealing sleeve 19 is fixedly installed at the outer edge between the float plate 17 and the fixed plate 15. An exhaust pipe 20 is fixedly inserted into one end face of the fixed plate 15, and the exhaust pipe 20 is located between the outer flexible sealing sleeve 19 and the inner flexible sealing sleeve 18. A static pressure level sensor 21 is provided, and the static pressure level sensor 21 is connected to the PLC control cabinet 1 for communication. The static pressure level sensor 21 is located between the inner flexible sealing sleeve 18 and the outer flexible sealing sleeve 19. The float plate 17 floating on the sewage surface can compress the internal space of the inner flexible sealing sleeve 18 and the outer flexible sealing sleeve 19. If the upward flow speed is too fast, the air will not be able to be discharged through the exhaust pipe 20 in time. This can be detected by the static pressure level sensor 21 and uploaded to the PLC control cabinet 1. This can monitor the phenomenon that the amount of sewage entering is too large at an instant, resulting in an excessively fast upward flow speed, and reduce the phenomenon that the excessively fast upward flow speed affects the safe operation of the integrated pump station.

[0025] Both pump 10 and pump 21 are fixedly connected to water supply pipes 22 at their output ends, and both water supply pipes 22 are fixedly connected to a common drainage main pipe 23 at their ends. Both water supply pipes 22 are equipped with flow control valves 24 inside, and both water supply pipes 22 are equipped with flow meters 25 on one side of the two flow control valves 24 inside. Both flow meters 25 are electrically connected to the PLC control cabinet 1, and both flow control valves 24 are connected to the execution communication submodule 13. With this configuration, the output flow of pump 10 and pump 21 can be monitored in real time, and the flow output can be controlled by the flow control valves 24 according to the flow rate.

[0026] A gas detection sensor 26 is installed on the upper side of the pump station body 2, and the gas detection sensor 26 is connected to the PLC control cabinet 1. The receiving terminal 7 has an alarm 27 built in. This setting can improve the monitoring of the space environment of the pump station body 2 and prevent the leakage of polluting gases. The gas detection sensor 26 can collect the concentration of harmful gases such as hydrogen sulfide, carbon dioxide or methane in real time.

[0027] The end face of the fixed plate 15 is provided with an air inlet 28, and the air inlet 28 is provided with a one-way valve 29. The air inlet 28 is located between the inner flexible sealing sleeve 18 and the outer flexible sealing sleeve 19. This arrangement makes it easy to replenish the air between the inner flexible sealing sleeve 18 and the outer flexible sealing sleeve 19 after the floating plate 17 moves down and recovers.

[0028] A cooling fan 30 is installed on the PLC control cabinet 1, and a dehumidifying heater 31 is fixedly plugged into the side wall of the PLC control cabinet 1. Both the cooling fan 30 and the dehumidifying heater 31 are electrically connected to the PLC control cabinet 1. With this arrangement, the temperature and humidity inside the PLC control cabinet 1 can be controlled, so that the components inside the PLC control cabinet 1 can operate in a suitable temperature and humidity environment, thereby reducing the damage rate.

[0029] A temperature sensor 32 and a humidity sensor 33 are fixedly plugged into one side of the end face of the PLC control cabinet 1. Both the temperature sensor 32 and the humidity sensor 33 are connected to the PLC control cabinet 1 for communication. The temperature sensor 32 is electrically connected to the cooling fan 30 through the PLC control cabinet 1, and the humidity sensor 33 is electrically connected to the dehumidifier 31 through the PLC control cabinet 1. This arrangement facilitates real-time monitoring of the temperature and humidity inside the PLC control cabinet 1 for control purposes.

[0030] The PLC control cabinet 1 is also equipped with an analog expansion module 34, which is connected to the PLC control cabinet 1 via a serial port. This configuration facilitates subsequent functional expansion.

[0031] The operating principle of the present invention is described as follows: Pump 10 and Pump 2 are installed inside the main body 2 of the pump station, and the execution communication submodule 12 and data acquisition module 5 are connected to Pump 10 and Pump 2. When Pump 10 and Pump 2 are working, PLC control cabinet 1 can monitor the real-time operating information of Pump 10 and Pump 2 through data acquisition module 5 and communication terminal module 4, and upload the operating information to receiving terminal 7 and cloud platform 8 in real time through IoT communication module 6. Relevant personnel can view the operating information of the main body 2 of the pump station in real time through handheld receiving terminal 7. When remote control is required, control information is transmitted to PLC control cabinet 1 through IoT communication module 6. Then, PLC control cabinet 1 controls Pump 10 and Pump 2 to perform corresponding operating actions through execution communication main module 12 and execution communication submodule 13.
