Description

Water supply user water information acquisition communication system

Technical Field

The utility model relates to a water gauge information acquisition field specifically is water supply user water information acquisition communication system.

Background

At present, the situation of water resource in China is very severe, the problems of water resource shortage, serious water pollution, deterioration of water ecological environment and the like are increasingly prominent, and the water resource is a main bottleneck for restricting the sustainable development of social economy. The establishment of scientific and sound water consumption data statistics is of great significance to the promotion of water-saving social construction.

At present, the domestic water management part adopts a manual meter reading mode, and the domestic water management part adopts an information meter reading mode. The manual meter reading has obvious defects, the meter reading time interval is longer, and the labor is consumed. The information meter reading mode is mainly a single-meter single-transmission data mode, the single-meter single-data transmission also has the following problems in the implementation, and the cost for sending data by a single water meter is too high. Because the water meter is mostly concentrated in the dark box, data can not be transmitted due to poor signals in the data transmission process.

Disclosure of Invention

The technical problem to be solved by the technical scheme is as follows: the problem of single transmission data of individual water gauge is solved, realize that the water gauge of physical region internal together concentrates the collection data, concentrates and send.

In order to realize the above purpose, the utility model discloses create the technical scheme who adopts: the utility model provides a water supply user water information acquisition communication system, is including setting up the water gauge data acquisition circuit in user's department, and more than or equal to 1 water gauge data acquisition circuit establishes ties the DTU module through RS485 or M-BUS circuit, and the DTU module sets up in network signal cover department, and the DTU module transmits data information to the signal station, and the signal station is connected cloud ware, and the PC customer end is connected to the cloud ware.

The beneficial effects of this technical scheme do: the problem of excessive cost for sending data by a single water meter is solved. The problem of because the water gauge is mostly concentrated in the darkbox, the data can not be transmitted because of the bad signal of data transmission in-process is solved.

The technical problems to be solved by the improvement of the technical scheme are as follows: power consumption during non-data transmission is reduced.

In order to realize the purposes, the invention creates the technical scheme adopted after improvement: the water meter data acquisition circuit controls the starting time point of the circuit by adopting the optical coupling solid-state relay.

The improved beneficial effects of the technical scheme are as follows: because the water gauge need not consume the electric quantity when using, only when carrying out data transmission, need consume the electric quantity. By using the optically coupled solid state relay, the power consumption is reduced.

The technical problem to be solved by the improvement of the technical scheme is as follows: the quality stability of the optical coupling solid-state relay is solved.

In order to realize the purposes, the invention creates the technical scheme adopted after improvement: the optocoupler solid-state relay is model AQW EH with loose electronics.

The beneficial effect after this technical scheme improves does: by testing the photo-coupled solid state relay AQW EH using loose electrons, 70% of the energy consumption can be reduced. The optical coupling solid-state relay AQW EH of the loose electron has high use stability and long service life of more than 20 years.

Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention in any way.

Example 1:

as shown in figure 1, a water information acquisition communication system for water supply users comprises a water meter data acquisition circuit arranged at a user, wherein more than or equal to 1 water meter data acquisition circuit is connected with a DTU module in series through an RS485 or M-BUS circuit, the DTU module is arranged at a network signal coverage position and transmits data information to a signal station, the signal station is connected with a cloud server, and the cloud server is connected with a PC client.

Taking a community as an example, two units of a building are generally used, each unit has N households, data obtained by a water meter data acquisition circuit of each household of the two units are summarized to a DTU module on the roof of the unit through data transmission, and the data collected by the DTU module is 2N households. The DTU module transmits data information to the signal station, the signal station is connected with the cloud server, and the cloud server is connected with the PC client side and used by a background manager.

Example 2:

as a further optimization of the above embodiment: as shown in fig. 2, the water meter does not require power for its operation, but instead requires 12VDC power to communicate with the DTU module of the water meter. If the power supply is always supplied, a relatively large energy consumption requirement is required for the energy storage module under the condition of no external power supply. The scheme of design research is that when the water meter data acquisition circuit sleeps, the power supply to instrument 12V is cut off, and what this scheme selected is that the optical coupling solid-state relay AQW EH of loose electron.
