Technical Field

[0001] The utility model relates to the technical field of gateway equipment, in particular to a gateway device for wireless Internet of Things operations on ocean-going fishing vessels. Background Art

[0002] Due to the harsh environment of offshore operations, there is a need for lighting in offshore fishing boats. The wattage of traditional fish attracting lights is often over 1000W, and the new LED fish attracting lights also require 100W. That is, if a 100W lamp is used, 2000 lamps will require 200,000W. The 220V voltage is 910Amp, and the generator cannot withstand the instantaneous switch power extraction and discharge. Therefore, the actual operation must be turned on in groups. The traditional way is to connect the wires to the central control room or to the sections in the engine room, such as Figure 5 As shown, however, the more wires there are, the heavier and more expensive the wires become, and the faster the wires are worn out by salt spray at sea. If we only estimate that each lamp wire is 20-30 kg, the weight will increase by 4000-6000 kg. The actual weight caused by winding will be higher than this increased weight, increasing the load of the generator's instantaneous loading and unloading, the fishing boat's oil consumption, and the cost of damage updates.

[0023] See also Figure 1-3The utility model provides a technical solution: a gateway device for wireless Internet of Things operation of ocean-going fishing vessels, including a box body 1, a shipboard power input unit capable of receiving 220V AC voltage and supplying power to the fishing vessel generator, an LED power switch unit capable of carrying the power input of the fish attracting lamp, an RS485 serial unit supporting the RS485 serial port, a communication unit capable of wireless communication, a control unit with low-power Internet of Things control, a battery unit and a waterproof and salt spray proof unit, the shipboard power input unit is electrically connected to the LED power switch unit, the LED power switch unit is electrically connected to the control unit, the control unit is electrically connected to the battery unit and the communication unit respectively, and the battery unit is electrically connected to the communication unit; the communication unit is used to make it have the characteristics of wireless communication.

[0024] The upper end of the box body 1 is fixed with an upper cover 2 by means of stainless steel screws 5. The shipboard power input unit is located at one end of the box body 1, the LED power switch unit and the RS485 serial unit are located at the other end of the box body 1, the control unit and the battery unit are both located inside the box body 1, and the side walls of the box body 1 are respectively provided with wires 6 for connecting the shipboard power input unit, the LED power switch unit and the RS485 serial unit. The waterproof and salt spray proof unit is provided on the side walls around the box body 1. When in use, Figure 4 As shown, installing this gateway device on each fish attracting light can effectively divide the fish into groups and segments and quickly light the lights, reducing the use of wires, making installation convenient, and reducing the instantaneous load of the fishing boat generator, thus achieving the purpose of light operation of the fishing boat;

[0025] The shipboard power input unit includes a removable fuse. One end of the fuse is provided with a connection port for 220V AC input. During operation, the onboard generator can be used directly to supply power to the fish attracting light without the need to pull additional low-voltage DC power. The maximum voltage that the fuse can withstand is 250V, and the maximum current that the fuse can withstand is 10A. If the power is accidentally tripped, the glue filling layer can be removed on site and the fuse can be adjusted and replaced. The shipboard power input design should take into account voltage surges, insulation, EMC protection and other designs.

[0026] The LED power switch unit includes a high-load digital relay switch, one end of the high-load digital relay switch is connected to the other end of the fuse, and the other end of the high-load digital relay switch is connected to the control unit. The high-load digital relay switch can carry the power input of the fish attracting lamp and allow the ESP CPU to control opening and closing.

[0027] The RS485 serial unit includes multiple RS485 communication serial ports. One end of the multiple RS485 communication serial ports is respectively connected to a pressure sensor, a wind speed sensor, a wind direction sensor and a temperature and humidity sensor. The RS485 communication serial port supports Modbus RTU serial port communication protocol, including support for Modbus RTU / TCP Server / TCP Client / UDP mode, TCP Alive check, etc. The fish attracting light and the environmental climate monitoring sensor can be connected according to actual use needs, so as to grasp the operating environment of the fishing boat in real time.

[0028] The communication unit includes a wireless network interface that can use Sub-G 802.11ah Wi-Fi HaLow wireless technology and an embedded antenna that can be used for short-range wireless communication. The embedded antenna is connected to one end of the wireless network interface. The wireless network interface uses a minimum bandwidth of 1M as the default setting. The Sub-G airspace is narrow and the minimum bandwidth is used to facilitate the coexistence of more device nodes at the same time. The 2000-ton hull of an ocean-going fishing vessel is about 90 meters by 15 meters, and a larger one has a range of 150 meters by 50 meters. Even so, it is still considered a small-scale transmission. The theoretical value of 802.11ah can be divided into a maximum of 8191 nodes. However, too many nodes in the same airspace will still cause various interference phenomena. Therefore, the embedded negative Gai n peak (or very low Gain peak) embedded antenna can avoid interference such as antenna feedback of multiple devices in a small range, which is conducive to the use of stable short-distance wireless communication. It supports ESP32 and 802.11ah TWT sleep mode. It enters sleep mode when not in use to extend the battery life. It is not easy to maintain equipment during offshore operations. Low-power wireless devices help remote operation. It uses shipboard power during operation and battery mode when not in operation. The device can also query the power capacity. When returning to the port, you can check whether the power supply needs to be replaced through the battery capacity query. It supports UDP multicast to transmit control signals. The central control software groups the devices. The number of generators in the group is arranged on site according to the number of generators on board. A multicast group consists of about 20 generators at 10A. The multicast opening or closing packet is sent three times at a time, with an interval of 500ms between each packet. There is an interval of more than 2 seconds between different multicast signal packets to prevent loss due to airspace congestion during multicast transmission. The gatekeeper mechanism is supported to monitor the wireless communication and light-on status, and automatically restart the device or turn on the light when it is confirmed that the device is disconnected or the fish-attracting light is not turned on. The gatekeeper monitoring is carried out in a single-wave mode in a polling manner after the multicast transmission is completed, which is convenient for monitoring and real-time connection recovery.

[0029] The control unit includes an ESP32 CPU, and the battery unit includes a lithium battery. One end of the lithium battery is electrically connected to the ESP CPU, and the other end of the wireless network interface is connected to the ESP CPU signal. The ESP32 CPU must support receiving multicast control request packets, which are controlled by the central control room through wireless communication. The ESP32 CPU has low power consumption and can be powered by batteries. It enters sleep mode when not set up and running. It supports automatic wake-up and manual wake-up of the ESP32 CPU and the communication unit. It supports TCP / TP protocol. The device can use text WEB UI and Telnet access settings, and provides batch setting software. The central control software can search for devices, group the numbered devices, and use multicast packets to send open and close control signals to maximize the use of wireless nodes in the same airspace. Communication interruption alarm, when the system input voltage is interrupted or cannot meet the normal operation of the system, automatically sends an alarm signal to the central control software, so that the management personnel can respond accordingly in real time. Support hardware door-keeping and firmware door-keeping mechanisms. If the communication status is suddenly interrupted under the input of shipboard power, it can automatically restart, restore the connection in time and send an alarm signal. Supports automatic restart at a scheduled or fixed time. You can define the automatic startup time (in hours), automatic shutdown time, or use the time server to obtain the correct time, and automatically restart or shut down the device at the specified time.

[0030] The waterproof and salt spray proof unit includes an inner coating and an outer coating. The outer coating is located on the outer surfaces of the box body 1 and the upper cover 2 and at the connection between the wire 6 and the box body 1. The inner cover plate 4 and the inner side plate 3 are installed inside the box body 1. The inner side plate 3 is fixed to the side wall of the box body 1. The inner cover plate 4 is located between the upper cover 2 and the box body 1. The inner coating is located between the inner side plate 3 and the side wall of the box body 1 and on the side of the inner cover plate 4 close to the upper cover 2. The inner coating and the outer coating make the gateway device meet the waterproof IP67 requirements. The box body 1 is designed with an outlet design, and a waterproof coating is applied at the outlet. The communication interface is designed at the tail of the line end, which is connected to the tail. Connect lamps or sensors to avoid water inflow, increase the protection effect of the gateway device, reduce the frequency of equipment replacement, reduce the excess wire weight when wired control, reduce fuel consumption, and the built-in battery unit provides control unit and remote control unit operation. The installation is completed when the ocean-going fishing vessel is docked. The battery is absolutely sufficient for multiple uses after leaving the port, reducing the maintenance time and cost of fishermen. PCBA is installed inside the box body 1, and then a layer of shelves is covered on the PCBA, and a glue coating is applied on the shelf. The two-layer waterproof and salt spray-proof design completely isolates the external and internal PCBA and battery controllers from contact.
