Description

Technical Field

[0001] The utility model relates to a valve control terminal, in particular to remote control and autonomous operation functions. Background Art

[0002] Traditional valve control relies on manual management. During normal weather conditions, when the external water level is lower than the water level in the pipe, the valve is open, allowing sewage to flow normally into the main river. However, during extreme rainstorms, the valve must be closed to prevent backflow from the main river. However, a single management area may have numerous valves and limited management personnel. In the event of an emergency, there may not be enough time to close the valves, causing backflow into surrounding factories and residential areas, resulting in significant economic losses.

[0003] Daily management of valves also relies on personnel inspections. As mentioned above, there are many valves in an area, and an inspection cycle will be very long. If there is a problem with the valve outside the inspection cycle, the personnel will not be able to discover the problem in the first time, and the timeliness will be greatly reduced. Utility Model Content

[0004] In response to the above problems, the present utility model provides an intelligent valve control terminal that improves monitoring efficiency.

[0005] Intelligent valve control terminal, including:

[0006] Main control MCU module, and connected to the integrated management platform through the communication module;

[0007] The ultrasonic ranging module is placed above the water level to be detected, and is used to collect water level height data. It is connected to the main control MCU module through the 485 communication module and transmits the monitored water level data to the main control MCU module;

[0009] The switch control module has one end connected to the AC contactor to directly control the movement of the valve, and the other end connected to the main control MCU module. The main control MCU module controls the opening, closing or stopping of the valve through the switch control module.

[0010] Specifically, the measurement module connected to the main control MCU module has one end connected to the mutual inductor in the control box for measuring the voltage and current in the control box, and the other end connected to the main control MCU module via SPI to transmit measurement data.

[0011] Specifically, the main control MCU module adopts the STC8A8K64D4-45I-LQFP64 chip.

[0012] Specifically, the communication module adopts EC800MCNGB-I03-SGNSA communication module.

[0015] Specifically, the switch control module includes an SRD-12VDC-SL-C relay and a 2n3904S-RTK / PS transistor;

[0016] The main control MCU sends a control signal to the 2n3904S-RTK / PS transistor to control the on and off of the transistor. The on and off of the transistor then drives the relay to be attracted and disconnected, thereby realizing the control of the relay by the main control MCU.

[0017] Specifically, the ultrasonic ranging module adopts the DYP-A01 ranging module.

[0018] Specifically, the measurement module uses an ATT7053C power acquisition chip.

[0019] The utility model uses a high-efficiency single-chip microcomputer as the main control MCU, so that the control terminal can operate efficiently and stably, integrate the data collected by each component, control the switch control module, and realize the control of the valve. A switch detection module is used to realize the monitoring of the valve status, and a 485 communication module is designed to realize the data collection of the ultrasonic ranging module. The use of a wireless communication module realizes remote control of the valve and monitoring of the valve status. When an emergency occurs, the valve closing instruction can be directly issued through the integrated management platform, thereby realizing remote valve closing operation. All valves are closed at the same time, which greatly saves time and ensures the personal safety of patrol personnel in extreme weather conditions. Since the situation of the valve and the control box can be viewed in real time, it can replace the management method of manual patrol, greatly improving efficiency and timeliness.

[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] Intelligent valve control terminal, including:

[0029] The main control MCU module is integrated into the intelligent valve control terminal and connected to the integrated management platform through the communication module;

[0030] The ultrasonic ranging module is placed above the water level to be detected, and is used to collect water level height data. It is connected to the main control MCU module through the 485 communication module and transmits the monitored water level data to the main control MCU module;

[0031] The switch detection module is integrated into the intelligent valve control terminal. One end of the switch detection module is used to connect to the valve junction box to collect the operating status of the valve and is connected to the main control MCU module to transmit the collected valve status data to the main control MCU module.

[0032] The switch control module is integrated into the intelligent valve control terminal. One end is connected to the AC contactor to directly control the movement of the valve, and the other end is connected to the main control MCU module. The main control MCU module controls the opening, closing or stopping of the valve through the switch control module.

[0033] The measurement module connected to the main control MCU module is integrated into the intelligent control valve control terminal. One end is connected to the mutual inductor in the control box to measure the voltage and current in the control box, and the other end is connected to the main control MCU module via SPI to transmit measurement data.

[0034] The utility model Figure 1-7 As shown in the figure, the intelligent control valve control terminal has two working modes when the equipment is running: automatic control mode and manual mode.

[0035] When running in automatic control mode, the valve opening and closing threshold data can be issued through the integrated management platform. The issued data is received by the communication module of the terminal. The communication module transmits the threshold data to the main control MCU through the UART serial port. The main control MCU will save the threshold data and then start to receive data from the 485 communication module, switch detection module and measurement module.

[0036] When the water level reaches the opening threshold and the valve is not in the fully open state, the main control MCU sends a valve opening command to the switch control module. When the water level reaches the closing threshold and the valve is not in the fully closed state, the main control MCU sends a valve closing command to the switch control module. When the valve is in the fully open or fully closed state, the main control MCU sends a stop command to the switch control module. When the device detects that the valve is in a fault state through the switch quantity detection module, the main control MCU will not send an operation command to the switch control module. When the external water level is higher than the internal water level, the main control MCU will send a valve closing command to the switch control module until it is fully closed. When the integrated management platform sends a valve opening, closing, or stop command to the terminal, the device will enter manual mode, and the action of the switch control module depends solely on the command issued by the integrated management platform.

[0037] The module used in the main control MCU of this case is STC8A8K64D4-45I-LQFP64 chip.

[0038] The 485 communication module uses the TPT485E-SO1R chip. The water level data collected by the ultrasonic ranging module is collected through the MUDBUS protocol.

[0039] Modbus is a serial communications protocol developed by Modicon (now Schneider Electric) in 1979 for communication with programmable logic controllers (PLCs). Modbus has become the de facto standard for industrial communications and is a common method for connecting industrial electronic devices.

[0040] The communication module used is the EC800MCNGB-I03-SGNSA. This ultra-compact LTE Cat 1 wireless communication module, designed specifically for the M2M and IoT markets, supports a maximum downlink rate of 10 Mbps and a maximum uplink rate of 5 Mbps. Its ultra-compact size and exceptional cost-effectiveness ensure data exchange with the host MCU via a UART serial port.

[0041] UART (Universal Asynchronous Receiver / Transmitter) is a communication protocol widely used in embedded systems, microcontrollers, industrial automation, and other fields. This article will provide an in-depth analysis of UART's core components, packet structure, baud rate selection, and its application in complex environments.

[0042] The switch detection module uses the NEC2502 optocoupler chip. The device connects a common node to the valve, which then feeds back three signals: open position, closed position, and fault. When any of these three signals is fed back to the optocoupler, it in turn feeds back a signal to the main MCU.

[0043] The switch control module utilizes a circuit composed of components such as SRD-12VDC-SL-C relays and 2N3904S-RTK / PS transistors. It consists of two relays, one for opening the valve and the other for closing it. When neither relay is engaged, the valve is in a stopped state. The two relays are interlocked, meaning that if one relay is engaged, the other is disabled.

[0044] The measurement module uses the ATT7053C power acquisition chip. The collected power parameters are transmitted to the main MCU via the SPI serial port. The voltage can be used to determine the power supply status within the control box, and the current can be used to determine whether the valve is operating normally.

[0045] SPI (Serial Peripheral Interface) is a high-speed, full-duplex, synchronous communication bus that uses only four pins on a chip, saving space and facilitating PCB layout.

[0046] Regarding the content disclosed in this case, the following points need to be explained:

[0047] (1) The drawings of the embodiments disclosed in this case only involve the structures involved in the embodiments disclosed in this case. Other structures can refer to the general design;

[0048] (2) In the absence of conflict, the embodiments and features of the embodiments disclosed in this case may be combined with each other to form new embodiments;
