Embodiment 1：Ship model experimental tank is that empty pond or liquid level do not reach object height, carries out water flood operations.It is real
As shown in Figure 2 to Figure 3, it is as follows that flow is embodied in the flow chart for applying example 1：
The liquid level h that administrator is needed by the setting of liquid crystal touch control screen 11, activation system.
Throw-in type liquid level sensor module 5 detects initial liquid level height h ', and h ' is transmitted to first by RS485 interfaces
The initial liquid level height h ' received is passed through ZIGBEE networks by ZIGBEE router-modules 7, the first ZIGBEE router-modules 7 again
9 are transmitted to ZIGBEE coordinator modules 10.
The initial liquid level height h ' that ZIGBEE coordinator modules 10 receive sends embeded processor to by USB interface
Module 4, the Liquid level software in embeded processor module 4 judge whether received initial liquid level height h ' is less than management
Liquid level h set by member.When less than embeded processor module 4 opens entering water electromagnetic valve mould by the first relay 14
Block 15, water inlet pipe conducting, carries out water flood operations.
In the injecting process, the constantly height h " of detection liquid level, and liquid level height in real time of throw-in type liquid level sensor module 5
Degree h " is transmitted to the first ZIGBEE router-modules 7 by RS485 interfaces, and the first ZIGBEE router-modules 7 are again receiving
Liquid level h " is transmitted to ZIGBEE coordinator modules 10 by ZIGBEE networks 9, what ZIGBEE coordinator modules 10 received
Liquid level h " sends embeded processor module 4 to by USB interface.Liquid level software constantly judges the liquid level received height
The liquid level h whether h " is equal to setting is spent, when equal to then closing entering water electromagnetic valve module 15 by the first relay 14, stop
Only water flood operations.
If in the injecting process, throw-in type liquid level sensor module 5 breaks down so that liquid level data h " loses
Very or the first ZIGBEE router-modules 7 break down, and can not correctly transmit liquid level h " numerical value, necessarily lead to pond
Liquid level rises steadily.It is red when pond liquid levels height h " increases to the highest liquid level position of the monitoring of infrared level sensors module 6
Outer liquid level sensor module 6 can transmit alarm signal to the 2nd ZIGBEE router-modules 8 by RS485 interfaces, and second
The alarm signal received is transmitted to ZIGBEE coordinator modules 10 by ZIGBEE router-modules 8 by ZIGBEE networks 9 again,
10 alarm signals received of ZIGBEE coordinator modules send embeded processor module 4 to by USB interface.Embedded place
Reason device module 4 receive after the alarm signal that infrared level sensors module 6 is sent can immediately by the first relay 14 come
Entering water electromagnetic valve module 15 is closed, stops water flood operations.Embeded processor module 4 passes through GSM by serial ports control gsm module 3
Communication network 2 sends warning short message to the mobile phone (the generally mobile phone of administrator) in advance Jing Guo certification, prompts administrator's liquid level
Height has reached extreme higher position, to be handled accordingly.
Embodiment 2：It is more than object height to have water or liquid level in ship model experimental tank, carries out the operation that discharges water.Embodiment 2
Flow chart as shown in Figures 2 to 4, specific implementation flow it is as follows：
The liquid level numerical value h that administrator is needed by the setting of liquid crystal touch control screen 11, activation system.
Throw-in type liquid level sensor module 5 detects initial liquid level height h ', and h ' is transmitted to first by RS485 interfaces
The initial liquid level height h ' received is passed through ZIGBEE networks by ZIGBEE router-modules 7, the first ZIGBEE router-modules 7 again
9 are transmitted to ZIGBEE coordinator modules 10.
The initial liquid level height h ' that ZIGBEE coordinator modules 10 receive sends embeded processor to by USB interface
Module 4, is judged whether received initial liquid level height h ' is more than by the Liquid level software in embeded processor module 4
Liquid level numerical value h set by administrator.When more than embeded processor module 4 is put by the second relay 16 to open
Water solenoid valve module 17, discharge tube conducting, carries out the operation that discharges water.
In the process of water release, the constantly height h " of detection liquid level, and liquid level height in real time of throw-in type liquid level sensor module 5
Degree h " is transmitted to the first ZIGBEE router-modules 7 by RS485 interfaces, and the first ZIGBEE router-modules 7 are again receiving
Liquid level h " is transmitted to ZIGBEE coordinator modules 10 by ZIGBEE networks 9, what ZIGBEE coordinator modules 10 received
Liquid level h " sends embeded processor module 4 to by USB interface.Liquid level software constantly judges the liquid level received height
Spend h " whether be equal to setting liquid level h, when equal to, then water-drainage solenoid valve module 17 is closed by the second relay 16,
Stop the operation that discharges water.Particularly, when the liquid level h of setting is 0, represent that administrator wishes tank water to give out light, this feelings
Pond has fraction ponding in order to prevent under condition, and when liquid level h " is 0, continuing to extend certain discharge time (can be
Set in software), water-drainage solenoid valve module 17 is closed again later, to achieve the purpose that completely to be allowed to dry water.
Embodiment 3：Remote operation controls ship model experimental tank automatic Control Systems of Liquids Height.The flow chart of embodiment 3 such as Fig. 5
Shown, specific implementation flow is as follows：
In ship model experimental tank automatic Control Systems of Liquids Height operational process, administrator can utilize the mobile phone 1 of certification
Control short message is sent to gsm module 3 by GSM communication network 2, so as to achieve the purpose that tele-control system.
After administrator sends the control short message comprising liquid level numerical value and activation system information to gsm module 3, GSM
Short message content is sent to embeded processor module 4 by module 3 by serial ports, and embeded processor module 4 judges the control received
The legitimacy of short message processed if as transmitted by unauthenticated mobile phone, then sends information warning and reminds administrator.If by
Transmitted by the mobile phone of certification, and short message content form is controlled to meet the requirements, then start ship model experimental tank liquid automatic control
System is operated accordingly；If controlling short message content form undesirable, send information warning and remind administrator.Such as
The liquid level numerical value of fruit control short message setting is more than initial liquid level height number, then the automatic water filling carried out such as embodiment 1 is grasped
Make；It is automatic to carry out putting such as embodiment 2 if the liquid level numerical value of short message setting is controlled to be less than initial liquid level height number
Water operates.
If administrator receives the SMS Tip of system exception, even if not at the scene, system emergency can be sent immediately and stopped
Short message is only controlled, simultaneously closes off entering water electromagnetic valve module 15, water-drainage solenoid valve module 17, tank level control system is in locking shape
State, it is necessary to which administrator is waited for input unlocking pin could system for unlocking.
It these are only embodiments of the present invention, description is more specific and in detail, but can not therefore be interpreted as pair
The limitation of the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art, the present invention is not being departed from
Under the premise of design, various modifications and improvements can be made, these belong to the protection domain of the claims in the present invention.
