Description

Technical Field

[0001] The invention relates to a ship lock automation monitoring technology, in particular to an on-site inspection wireless handheld terminal for unmanned ship locks, which is used to know the ship lock operation status at any time and handle emergencies during the centralized control of the ship lock. Background Art

[0002] With the development of technology, the control and operation of ship locks has gradually developed from the previous on-site machine room of each lock to centralized control. A unified centralized control center has been set up for multiple cascade ship locks in multiple river basins to control multiple line ship locks in a region or multiple cascade ship locks in a river basin. Under the centralized control mode, the on-site machine room of the ship lock cancels the fixed duty posts and only retains a small number of on-site mobile patrol personnel, forming a remote centralized management and control, unmanned on-site, and few patrol ship lock operation management mode. This realizes the joint adjustment and control of ship locks, improves navigation efficiency, and reduces operating costs.

[0003] After the fixed on-duty personnel in the on-site machine room are cancelled, if the on-site inspection personnel find any abnormal situation in the operation of the ship lock and the process of ships entering and leaving the lock during the inspection, the ship lock needs to be shut down or the valve needs to be closed urgently. However, the on-site machine room is far away and it is impossible to get to the on-site machine room in time for operation. At present, most of the operators in the centralized control center are contacted through handheld walkie-talkies or mobile phones. This method has many restrictions and takes a long time to communicate and deal with. There is a risk of delaying the timing of handling and escalating the consequences of the situation.

The operation button and switch are both physical keys with anti-mistouch function, and the physical keys are preferably concave structures, and the effective touch position of the physical keys is lower than the panel of the housing 1; the liquid crystal display unit includes a liquid crystal display screen 2, which is used to display the current operating status of the lock and the status of the handheld terminal itself in real time, and to display the battery power and wireless signal strength; the number of lines of displayed characters and graphics is not less than 3; a vibration prompt module is used for vibration prompts of important information, so that you will not miss it even if you put it in your pocket; and a dial switch 3 is used to select the lock to be monitored and operated, and to select the broadcast area during on-site broadcasting, so that one terminal device can be used for multi-line lock patrol. Among them, the wireless communication base station includes a fiberglass antenna, a feeder and a base station module, and the base station module has a built-in wireless Lora protocol and industrial Ethernet protocol conversion function. The wireless communication base station adopts two sets of mutually redundant configurations to improve the reliability of the base station. The communication distance covered by the wireless communication base station is greater than 3 kilometers. The conversion between the wireless Lora protocol and the industrial Ethernet protocol is completed through a dedicated protocol conversion chip built into the base station module, without the need for conversion through an external data server, to ensure the real-time and reliability of communication.

[0034] In this embodiment, the emergency operation button 4 is also used to issue an emergency valve closing command to immediately stop the current water filling or water discharge state of the lock chamber to avoid the occurrence of dangerous accidents. The emergency operation button 4 is also used to issue a command to open or close the lock chamber or the pilot channel lighting. Among them, the wireless Lora protocol is used to communicate with the wireless communication base station, and the communication distance is greater than 3 kilometers. The wireless communication base station and the lock control system are directly connected and communicated through the industrial Ethernet port. The operation command signal issued by the emergency operation button 4 is sent to the lock control system through the wireless communication base station; and the lock on-site inspection wireless handheld terminal reads the current operation status of the lock from the lock control system to conduct on-site inspection monitoring and emergency operation of the lock operation to ensure the safe operation of the lock.

[0035] This embodiment is provided with operation buttons such as "emergency stop, pause, forced valve drop, lighting on, lighting off, test", and also provided with a "0, 1, 2, 3" lock chamber number selection dial switch 3 (0 means exit, 1, 2, 3 correspond to the first, second, and third line ship locks respectively), and any of the three-line ship locks can be selected for monitoring operation to meet the patrol personnel's state monitoring and emergency operation switching requirements for the three-line ship lock. This button involves emergency operation, and it is necessary to ensure that emergency operation instructions can be issued immediately at any time, so the keyboard lock function similar to the mobile phone button cannot be set. The wireless handheld terminal uses the wireless Lora protocol to communicate with the wireless communication base station for data reception / transmission bidirectionally. The wireless communication base station also has the protocol gateway conversion function to convert the wireless Lora protocol data into industrial Ethernet data. The wireless communication base station is connected to the ship lock control system PLC Ethernet switch through an Ethernet interface (using Modbus TCP, Profinet, OPC and other Ethernet-based communication protocols) and a Category 5e cable (optical fiber is required for distances exceeding 100 meters). The wireless handheld terminal and the ship lock control system PLC can issue operation commands and obtain the ship lock operation status. The PLC program of the ship lock control system adds function blocks for communication processing with the wireless base station and response to handheld operation commands. The communication processing function block has the function of self-tuning and self-diagnosis of communication data. If abnormal communication data is found, the operation command will be refused and an alarm will be issued to avoid false operation.

[0036] The present invention is a portable monitoring device for on-site inspection personnel of a ship lock to understand the operation status of the ship lock at any time and deal with emergencies in a timely manner, and is equipped with a set of wireless transceivers connected to the ship lock control system. A set of wireless transceivers is set at the ship lock site of each ship lock management office, and the wireless signal range can cover each ship lock on-site inspection area under the ship lock management office. Each on-site inspection personnel carries a wireless handheld terminal. Once an abnormal situation is found in the operation of the ship lock equipment or the process of ships entering and leaving the lock, a pause or shutdown command can be immediately issued through the emergency operation button 4 to terminate the operation of the current ship lock, and an emergency valve closing command can also be issued to immediately stop the current ship lock chamber filling and draining state to avoid the occurrence of dangerous accidents. The wireless handheld terminal can also be used to open and close the lock chamber and the pilot channel lighting.

[0037] The present invention is easy for on-site patrol personnel to carry (its external dimensions are similar to those of a 6.5-inch mobile phone), can display the current operation of the lock, the upcoming actions during automatic operation, and fault information (with an information vibration prompt function), and can also display the signal strength, battery power, current operation of the lock and other information of the handheld terminal, and can perform all emergency operations of the lock and daily patrol operations such as turning on and off the lighting. A built-in dedicated chip is used to complete the conversion between the wireless Lora protocol and the industrial Ethernet protocol, without the need for conversion through an external data server. The base station is directly connected to the lock control system PLC through industrial Ethernet to ensure the real-time and reliability of data communication and emergency operations, and the data response cycle does not exceed 1 second. One handheld terminal can be used for patrolling up to three locks in the same section of the same lock management office (selected by the dial switch 3 on the handheld terminal). It is equipped with a test button, which can test the effectiveness of the handheld terminal operation anytime and anywhere.

[0038] The present invention adopts a dedicated wireless communication protocol. One base station can cover the multi-line ship lock range of the same ship lock management office (supporting up to three-line ship locks), and supports multiple handheld terminals to communicate with one base station in real time at the same time, so that on-site patrol personnel can understand the current ship lock passage process in real time and perform various emergency operations. It is applicable to all current ship locks. In order to ensure the reliability and real-time operation of the handheld terminal, the wireless handheld terminal uses the Lora protocol to communicate directly with the ship lock control system PLC through the base station, and cannot perform data conversion through devices such as servers. The two base stations are mutually standby and redundantly operated, covering the patrol routes of three ship locks, and the communication distance is greater than 3 kilometers. The wireless handheld terminal adopts a pocket-sized design, which is convenient for on-site patrol personnel to carry. It adopts an anti-mistouch button with a built-in vibration function. The dial switch 3 is used to select the No. 1, 2, and 3 ship locks and exit, which is convenient for on-site patrol personnel to carry. The button anti-mistouch function is mainly to prevent the handheld terminal from being squeezed and sending a signal by mistake when it is in a pocket or held by hand. The button is preferably a concave structure, and the effective touch part of the button is lower than the panel of the housing 1, ensuring that only human fingers can send an operation signal. It uses a rechargeable battery, and the charging cable uses the universal TYPE-C interface for mobile phones. The wireless handheld terminal is equipped with a liquid crystal display unit, which can display information such as battery power and signal strength, the currently monitored ship lock, the current operating status of the ship lock, fault alarm and shutdown reasons, the action position of the shutdown button, the automatic conversion of the entry signal light, and the countdown time for the automatic opening and closing of the gate valve (action notice and alarm information can be vibrated to prompt), which can prompt the upcoming and ongoing actions and fault conditions of the fully automatic ship lock, meeting the needs of "unmanned, less-staffed emergency" smart ship lock operation and daily inspection and on-site debugging of the fully automatic ship lock. When the on-site inspectors broadcast through the handheld walkie-talkie, they can select the broadcast area (such as the lock chamber, upstream pilot channel, downstream pilot channel, etc.) through the wireless handheld terminal.

[0039] The on-site inspection personnel carry it and issue operation instructions through the emergency operation button 4, and display the current operation status of the lock through the LCD screen 2; the wireless communication base station is installed in the lock control room, the base station is equipped with an antenna feed system, and one base station can communicate with multiple wireless handheld terminals within a range of not less than 3 kilometers, and transmit the received handheld terminal operation instructions to the PLC, and transmit the lock operation status information output by the PLC to the handheld terminal for display; the lock control system PLC is installed in the lock control room, and after receiving the operation instructions issued by the wireless handheld terminal, it performs logical judgment and completes related operations.

[0040] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
