Embodiment 1

[0057] Embodiment 1: The water tank for the ship model test is empty or the liquid level has not reached the target height, and the water injection operation is performed. The flow chart of embodiment 1 is as Figure 2 to Figure 3 As shown, the specific implementation process is as follows:

[0058] The administrator sets the required liquid level height h through the liquid crystal touch screen 11, and starts the system.

[0059] The input liquid level sensor module 5 detects the initial liquid level height h', and transmits h' to the first ZIGBEE router module 7 through the RS485 interface, and the first ZIGBEE router module 7 then transmits the received initial liquid level height h' through the ZIGBEE The network 9 transmits to the ZIGBEE coordinator module 10 .

[0060] The ZIGBEE coordinator module 10 transmits the received initial liquid level height h' to the embedded processor module 4 through the USB interface, and the liquid level control software in the embedded ...

Embodiment 2

[0063] Embodiment 2: There is water in the ship model test pool or the liquid level exceeds the target height, and the water release operation is performed. The flow chart of embodiment 2 is as Figure 2 to Figure 4 As shown, the specific implementation process is as follows:

[0064] The administrator sets the required liquid level height value h through the liquid crystal touch screen 11, and starts the system.

[0065] The input liquid level sensor module 5 detects the initial liquid level height h', and transmits h' to the first ZIGBEE router module 7 through the RS485 interface, and the first ZIGBEE router module 7 then transmits the received initial liquid level height h' through the ZIGBEE The network 9 transmits to the ZIGBEE coordinator module 10 .

[0066] The ZIGBEE coordinator module 10 transmits the received initial liquid level height h' to the embedded processor module 4 through the USB interface, and the liquid level control software in the embedded processor...

Embodiment 3

[0068] Embodiment 3: remote operation control system for automatic liquid level control of ship model test pool. The flow chart of embodiment 3 is as Figure 5 As shown, the specific implementation process is as follows:

[0069] During the operation of the automatic liquid level control system of the ship model test pool, the administrator can use the authenticated mobile phone 1 to send control messages to the GSM module 3 through the GSM communication network 2, so as to achieve the purpose of remote control of the system.

[0070] When the administrator sends a control text message containing the liquid level value and start-up system information to the GSM module 3, the GSM module 3 transmits the content of the text message to the embedded processor module 4 through the serial port, and the embedded processor module 4 judges the received control message. The legality of SMS, if it is sent by an unauthenticated mobile phone, a warning message will be sent to remind the ad...

Abstract

The invention discloses a ship model experimental tank liquid level automatic control system which is composed of an embedded processor module, a liquid crystal touch screen, a power supply, a certified mobile phone, a GSM communication network, a GSM module, a first liquid level sensor module, a second liquid level sensor module, a first transmitter module, a second transmitter module, a receiver module, a wireless network, a first relay, a second relay, a water inlet electromagnetic valve module, and a water discharge electromagnetic valve module. According to the ship model experimental tank liquid level automatic control system and a control method thereof provided by the invention, a manager does not need to care about the initial liquid level height. As long as the required liquid level height is set, the system can automatically judge whether water injection or water discharge is conducted. Unattended water injection and discharge can be realized, and liquid level height detection can be controlled in real time. The system has a remote operation function and high control precision, and is safe and reliable. The invention further discloses a ship model experimental tank liquid level automatic control method.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and relates to an automatic liquid level control system, in particular to an automatic liquid level control system and a control method for a ship model test pool. Background technique [0002] The ship model test pool is an important facility for ship performance research and testing, and a place for ship model tests. Large-scale equipment in marine engineering basically needs to be tested on the tank model before it is built and launched. Through the test, more reliable hull motion data and structural force conditions can be obtained, thereby providing a reliable basis for the design of marine equipment. [0003] At present, the water injection, water discharge and liquid level adjustment of the ship model test tank before and after the test are basically done manually. Since the water volume is not easy to control, the water discharge time is very long and difficult to calculate. Onc...
