Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the structured flowchart based on anallatic static liquid level of the embodiment of the present invention.The server module 4 that static liquid level comprises the closed container 1 being located at reference point and monitoring point, the level gauging module 2 being arranged on closed container 1 top and multiple wireless transport module 3 and is arranged on the closed container 1 of predetermined monitoring point.Monitoring point is the point needing to monitor sedimentation, and reference point is previously selected point, and reference point sedimentation can not occur.The quantity of monitoring point is more, and correspondingly, the quantity of closed container 1 is also more.
Closed container 1 is for splendid attire transparency liquid, and each closed container 1 passes through pipeline communication.Wherein, because each closed container 1 is by pipeline communication, so the transparency liquid in each closed container 1 can flow mutually, the liquid level in all like this closed containers 1 is just in same level.When there is sedimentation in certain monitoring point, the closed container 1 meeting sedimentation together thereupon at this monitoring point place, liquid level now in this closed container 1 will lower than the liquid level in the closed container 1 of reference point, transparent liquid knows from experience the closed container 1 flowing into this sedimentation from other closed container 1, until the liquid level in each closed container 1 is in same level again.
Level gauging module 2 comprises laser instrument and photodetector, and laser instrument is used for sending laser, the laser that photodetector reflects for the liquid level receiving transparency liquid to the liquid level of transparency liquid, and the level value obtaining transparency liquid according to reflects laser.Wherein, the top of each closed container 1 is all provided with level gauging module 2, and after the laser reflection that laser instrument is launched returns to be arrived by photoelectric detector, photodetector can export an electric signal, and namely this electric signal represents a level value.Owing to adopting laser, thus the level value in closed container 1 can be measured exactly.
Wireless transport module 3 is connected with level gauging module 2, for gathering the level value that level gauging module 2 obtains, and by wireless transmission method, level value is sent to server module 4.Multiple wireless transport module 3 forms a LAN (Local Area Network) with server module 4.Certainly, static liquid level can increase the quantity of wireless transport module 3 and server module 4, thus can form multiple LAN (Local Area Network), and each LAN (Local Area Network) carries out networking, can realize the networking monitoring of multizone.
The level value that server module 4 sends for the wireless transport module 3 receiving each monitoring point, and the relative settlement of each monitoring point is obtained according to the level value received, thus realize level analysis.Wherein, the level value that each wireless transport module 3 collects is sent to server module 4 with wireless transmission method, is therefore connected without the need to data line between each closed container 1, greatly can reduce the workload of installing, and improve the stability of system.
Further, in the present embodiment, server module 4 specifically for receiving the acquisition interval that pre-enters of user, and sends acquisition instructions according to acquisition interval to the wireless transport module 3 of each monitoring point; Wireless transport module 3, specifically for after receiving acquisition instructions, starts liquid level measurement module 2, gathers the level value that level gauging module 2 obtains, and transmits the level value that level gauging module 2 collects.
Below in conjunction with Fig. 2, the principle of work of the embodiment of the present invention based on anallatic static liquid level is described.In the present embodiment, the quantity of closed container 1 is two, is respectively 1A and 1B.Closed container 1A is positioned at reference point, and closed container 1B is positioned at monitoring point.When installing closed container 1A and closed container 1B, ensure that the level value in two closed containers is equal, as shown in Fig. 2 (a), now monitoring point and reference point are positioned in same level.
When there is sedimentation in monitoring point, the closed container 1B at monitoring point place can sedimentation together thereupon, liquid level now in closed container 1B can lower than the liquid level in closed container 1A, liquid can flow into closed container 1B from closed container 1A, so the liquid level in closed container 1A can decline, liquid level in closed container 1B can rise, until the liquid level in two closed containers is in same level, as shown in Fig. 2 (b).
If the level value now in closed container 1A is H1, the level value in closed container 1B is H2, then the liquid level difference in two closed containers can be expressed as:
ΔH＝H2-H1
As can be seen from Fig. 2 (b), now the sedimentation value of monitoring point is exactly Δ H, the level value that level gauging module 2 in closed container 1A, 1B is measured is respectively H1 and H2, and by wireless transmitter module 3, data being sent to server module 4, server module 4 just can go out the sedimentation value at now monitoring point place according to above-mentioned formulae discovery.
In the present embodiment, static liquid level also comprises the wireless public communication network access module (not shown) be integrated in server module 4, server module 4 is also for being transferred to wireless public communication network access module by the relative settlement of each monitoring point, wireless public communication network access module is for accessing public network, and the measurement result of each monitoring point is sent to the Regional Control Center 5 of far-end, monitor with feasible region remote networking.As shown in Figure 3, server module 4 forms a WLAN with the wireless transport module 3 on each closed container 1.Server module 4 sends acquisition instructions to the wireless transport module 3 on each closed container 1, laser instrument is started after each wireless transport module 3 receives acquisition instructions, then gather level value and send to server module 4, level value in the closed container 1 at the level value in the closed container 1 at each monitoring point place and reference point place contrasts by server module 4, calculate the sedimentation value of each monitoring point, then utilize wireless public communication network access module result of calculation to be sent to the Regional Control Center 5 of far-end by public network, so just achieve long-range automatic monitoring.
By the way, the embodiment of the present invention based on anallatic static liquid level by conjunction with optical ranging and wireless networking, thus the static level monitoring of high precision, robotization and even region networking can be realized, there is measuring error little, long working life, the advantage such as flexible for installation, easy.
