The rain gage device
Technical field
The utility model relates to a kind of rain gage device, belongs to the rainfall measurement technical field.
Background technology
In recent years, the occurrence frequency of the various places disaster that the frequent extreme weather events occurred causes significantly increases, and the disasters such as the flood particularly caused by heavy rain, rubble flow, had a strong impact on various places economic development and life property safety of people.How the real-time rainfall data in each zone of acquisition accurately and timely in rainfall, seem particularly important for the flood control disaster relief work provides instruction.
For only having the fixedly rainfall early warning system of rainfall monitoring equipment to be difficult to reach this requirement, for some rainfall some areas pockety and extreme terrain geomorphologic subregion (as high mountain, valley etc.), the portable rainfall real-time monitoring system of part need to be set, not only require its function that can complete rainfall monitoring and will be convenient to mobile, can locate and the wireless communication technique such as GPRS by GPS, make at the rainfall monitoring central station and obtain its rainfall data, in conjunction with its concrete geographic position of GIS information acquisition.By fixing and portable rainfall monitoring equipment, combine, for casualties and the property loss that effectively reduces or avoid disaster to cause provides strong assurance.
To effective measurement of rainfall amount, to industrial and agricultural production, people's lives and prevent natural disaster and have very important significance.At present, existing rainfall monitoring system is wired mode and wireless mode substantially.Wired mode has its intrinsic defect, as the complexity that connects up, subject to thunderbolt, installation and maintenance cost high, easily go to pot etc.; Wireless mode, relatively more commonly used is radio-frequency (RF) receiving and transmission module at present, has the technological deficiency that signal is easily intercepted by barriers such as mountains.For the various technological deficiencies of above appearance, a kind of rain gage device is proposed, can address the above problem.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of rain gage device is provided, and it has improved measuring accuracy, simple in structure, can shift at any time, has improved the ageing of rainfall measurement simultaneously.
The utility model solves the problems of the technologies described above the technical scheme of taking: a kind of rain gage device, it comprises rainfall measurement module, main control circuit, wireless transport module and the supply module that power supply is provided to main control circuit, wireless transport module and rainfall measurement module respectively, wherein, the rainfall measurement module, it comprises metering circuit and, for accepting and measure the tilting bucket rain of rainfall data, tilting bucket rain is connected with metering circuit; Main control circuit, it is connected with metering circuit, and opens or close and receive the rainfall data information that metering circuit is transmitted to the rainfall measurement module drive for periodically transmitting unlatching or closing control signal; It also is connected with wireless transport module, and for by wireless transport module, rainfall data information being passed to the external data center and receives the external control instruction.
Further, the periphery of described rainfall measurement module, main control circuit, wireless transport module and supply module is equipped with housing.
Further, described housing is made by corrosion-resistant engineering plastics.
Further, described supply module comprises solar panel, power control circuit, battery capacity detection circuit and the accumulator be connected successively.
Further, described wireless transport module comprises radio transmitting and receiving chip, power amplification element, filter element and the antenna be connected successively.
After having adopted technique scheme, the utility model is simple in structure, adopt tilting bucket rain to measure rainfall, measuring accuracy is higher, and periodically wake tilting bucket rain up and detect, reduced power supply cost, and in real time rainfall data information has been passed to the external data center by wireless transport module, improve the ageing of rainfall measurement, also increased its removable performance simultaneously.

Embodiment
For content of the present utility model more easily is expressly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Fig. 1 ~ 3, a kind of rain gage device, it comprises rainfall measurement module, main control circuit, wireless transport module and the supply module that power supply is provided to main control circuit, wireless transport module and rainfall measurement module respectively, wherein, the rainfall measurement module, it comprises metering circuit and, for accepting and measure the tilting bucket rain of rainfall data, tilting bucket rain is connected with metering circuit; Main control circuit, it is connected with metering circuit, and opens or close and receive the rainfall data information that metering circuit is transmitted to the rainfall measurement module drive for periodically transmitting unlatching or closing control signal; It also is connected with wireless transport module, and for by wireless transport module, rainfall data information being passed to the external data center and receives the external control instruction.The periphery of rainfall measurement module, main control circuit, wireless transport module and supply module is equipped with housing.Wireless transport module is by wireless network and external data center swap data, and wireless network can be different network, according to the real network situation, selects different wireless communication networks.
Main control circuit adopts super low power consuming single chip processor, only when the tilting bucket rain measurement data, just opens its power supply, at ordinary times in off-position, makes the consumed power of system high power device be down to minimum.This single-chip microcomputer adopts low-power consumption park mode and wakes timer up, make single-chip microcomputer in the overwhelming majority time in shutdown mode, just periodically wake tilting bucket rain detection rainfall up, judge whether to send alerting signal.
Housing can select corrosion-resistant engineering plastics or stainless steel material to make.
As shown in Figure 2, supply module comprises solar panel, power control circuit, battery capacity detection circuit and the accumulator be connected successively.Major function is to assist main control circuit to realize effective utilization of electric energy.
Wireless transport module comprises radio transmitting and receiving chip, power amplification element, filter element and the antenna be connected successively.
As shown in Figure 3, the control procedure of shown main control circuit comprises the steps:
S01: system initialization parameter;
S02: enter the timing dormancy state;
S03: judge whether to rain, if it is perform step S04, otherwise carry out step S03;
S04: open the rainfall measurement module;
S05: metering circuit, read the rainfall value;
S06: be transferred to wireless transport module;
S07: wireless transport module transfers data to the external data center by wireless network;
S08: close the rainfall measurement module;
S09: arrange and measure interval next time;
S10: enter dormancy, carry out S04 after wake-up waiting;
Above-described specific embodiment; technical matters, technical scheme and beneficial effect that the utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
