Background technology
Urban waterlogging is commonplace in China at present, from the point of view of the region occurred, occurs mainly in some littorals in the past
Gesture is than relatively low area, and present inland city the most often occurs.Past town site area is little, and selectable region is compared
Greatly, the most all select the area construction that physical features is higher, and present, and urban land is the most nervous, and selectable leeway is few.
Secondly, the incidence rate of some locality in city is higher, such as viaduct.Construction draining along with modern city
Also there are many new problems in waterlogging aspect.Such as under a lot of local viaducts, can hydrops after rainfall.Cross street underpass,
Railway bridge, highway bridge there is also similar situation.
The most manually timing detection of traditional monitoring method, relies on the information of range estimation or other information platforms to carry out pre-
Alert.Traditional Man monitoring system realizes there is following deficiency: the mode of personal monitoring can not realize real-time daytime measurement, nothing
Method realizes automatization.
To aspects such as real-time daytime measurement, automatic monitorings in traditional monitoring system, and system install implement, after
The aspects such as phase maintenance have some limitations, it is difficult to meet current requirement.
Summary of the invention

Complete data management, transmission simultaneously.Arranging under automatic drainage pattern corresponding, system can realize automatically gathering.
Internal system is designed with laser ranging module, and for water level monitoring, its certainty of measurement reaches ± 2mm, will pass during use
The RXD of sensor output is connected with the TXD of micro controller series, and TXD is connected with the RXD of micro controller series.When laser beam direct projection
During to liquid level, diastimeter receiving terminal is returned in laser-bounce, by ASCII protocol instruction read present laser probe with liquid level away from
From.
For meeting the requirement being wirelessly transferred, the scheme that the design uses is: using LoRa wireless module, microcontroller passes through
Control LoRa module, the data collected are reported.Interface between microcontroller and wireless module uses asynchronous communication
Mode, when not data communication, microcontroller can be automatically switched off the power supply of wireless module, to reduce the overall merit of system
Consumption.
During design complex in view of field working conditions residing for system, protection after wiring, the reliability of power supply etc. are all
Being difficult to ensure that, therefore, native system design, by solar panel charging, lithium battery power supply mode, thoroughly solves a difficult problem for scene power supply.
The built-in wireless data transfer module of simultaneity factor, the problem solving data transmission, it is achieved that the wireless penetration of system.
For realizing round-the-clock real-time measurement, systems control division divides and can realize automatically controlling, and designs supporting aluminum matter compartment, with
Guarantee system can the most normally use.Simultaneously for making measurement data seriality, Design of Monitor has FLASH memory, when micro-
After controller collects the waterlevel data of present laser distance measuring sensor, automatically store.And it is stable at LORA wireless networking
After, certainly it is about to data and uploads.Answer the collection automatic for long term monitoring of system data storage function, the requirement of preservation, this prison
Survey the memorizer that instrument selects be M25P16, M25P16 be a with advanced write-protect mechanism and the 2M of high speed SPI bus access
Byte serial flash storage, this memorizer main feature: the memory space of 2M byte, point 32 sectors, each sector 256
Page, every page of 256 bytes；Writing 1 page data required time is 1.4 ms (representative values)；Can monolithic erasing and monoblock wipe: 2.7～
3.6 V single supply supply voltages；Spi bus and 50 MHz data transfer clock frequencies；The erasable number of times in every sector ensures 100,000 times.
The beneficial effects of the utility model:
In sum, monitoring system of the present utility model is automatically controlled by microcontroller, can realize drainage pipeline networks
Level measuring function, and be transmitted by wireless, and system be solar powered device, therefore can realize real-time whole day
Wait the function measured, compensate in traditional monitoring system not enough.
