Detailed Description
Referring to fig. 1, the invention provides a telemetering terminal for preventing the report omission of rain amount, which comprises: the device comprises a first detection branch, a second detection branch, a first tipping bucket 1, a connecting plate 3, a second tipping bucket 2, a mounting bracket, a collected signal output module and a main control module.
The first detection branch circuit and the second detection branch circuit are connected in parallel, and a first normally-open switch K1 and a second normally-open switch K2 are arranged on the first detection branch circuit and the second detection branch circuit respectively. The connecting plate 3 is installed on the installing support, and first tipping bucket 1 and second tipping bucket 2 are installed respectively at the relative both ends of connecting plate 3 and form the seesaw structure, and first tipping bucket 1 and second tipping bucket 2 all are articulated with connecting plate 3, and overturn when first tipping bucket 1 and second tipping bucket 2 are in the state of movement orbit minimum and empty the rainwater. Thus, in the present embodiment, the first skip bucket 1 receives rainwater at the highest point of the track, and at this time, the second skip bucket 2 turns over at the lowest point of the track; when the rainwater amount in the first tipping bucket 1 reaches a fixed value, the connecting plate 3 rotates under the weight difference between the first tipping bucket 1 and the second tipping bucket 2, the first tipping bucket 1 rotates downwards, and meanwhile, the second tipping bucket 2 which is in an empty bucket state after the rainwater is tipped moves upwards; when the second tipping bucket 2 bears a fixed-value rainfall at the highest point of the track, the connecting plate 3 continuously turns. Therefore, the first tipping bucket 1 and the second tipping bucket 2 are mutually linked through the seesaw structure, when the first tipping bucket 1 or the second tipping bucket 2 is blocked in the process of dumping rainwater at the lowest point of the track, the first tipping bucket or the second tipping bucket 2 at the track position can be prized through the weight increase of the second tipping bucket at the highest point of the track or the movement of the second tipping bucket 2, the movement fluency of the first tipping bucket 1 and the second tipping bucket 2 is ensured, and the automatic adjustment capacity of the first tipping bucket 1 and the second tipping bucket 2 to abnormal states is improved. This embodiment is total, is favorable to avoiding single tipping bucket because the risk that reasons such as foreign matter jam can not in time overturn, is favorable to the rainfall statistical process in, and first tipping bucket 1 and second tipping bucket 2 are through the accurate degree of the rotation measurement rainfall that makes a round trip.
In the present embodiment, the first dump bucket 1 is connected to the first normally open switch K1, and the first normally open switch K1 is closed when the first dump bucket 1 rotates downward at the angle r from the horizontal plane on the descent trajectory of the first dump bucket 1. On the descending track of the second dump bucket 2, when the second dump bucket 2 rotates downwards from the horizontal plane by an included angle r, the second normally open switch K2 is closed. And r < w, wherein w is an included angle between the first tipping bucket 1 and the second tipping bucket 2 when the first tipping bucket and the second tipping bucket descend to the lowest positions and the horizontal plane.
The signal output end of the first detection branch and the signal output end of the second detection branch are both connected with the signal input end of the collected signal output module, and the output end of the collected signal output module is connected with the input end of the main control module.
The acquisition signal output module is used for sending rainfall metering signals to the main control module when the first normally-open switch K1 is closed or the second normally-open switch K2 is closed, and the main control module is used for calculating rainfall according to the rainfall metering signals and outputting a metering result.
So, in this embodiment, first normally open switch K1 and second normally open switch K2 have the closure state of certain duration respectively at first tipping bucket 1 and the decline in-process of second tipping bucket 2, so, in this embodiment, for prior art, change rainfall sensing signal into process signal by instantaneous signal, be favorable to avoiding the monitoring omission of first normally open switch K1 and second normally open switch K2 closure state, thereby be favorable to avoiding the rainfall to miss reporting. In addition, in the embodiment, the first tipping bucket 1 and the second tipping bucket 2 are linked by a seesaw structure, so that the condition that the rainfall is reported more due to the fact that a rainfall detection switch is closed for a long time because a single tipping bucket cannot be timely reset due to movement obstacle can be avoided.
During specific implementation, in order to ensure the continuity of the closed states of the first normally-open switch K1 and the second normally-open switch K2 in the descending process of the first tipping bucket 1 and the second tipping bucket 2 respectively, the rainfall sensing signal is ensured to be accurately measured, and the phenomenon that the rainfall is reported more and r is less than or equal to w/3 due to the fact that the first normally-open switch K1 and the second normally-open switch K2 are too long in closing time is avoided.

Therefore, when the first tipping bucket 1 is positioned at the high end, the first tipping bucket 1 can be prevented from overturning at the high end of the motion track through the rebounding of the first spring 4, so that the first tipping bucket 1 is ensured to bear rainwater upwards at the high end of the motion track; when the first dump bucket 1 is at the lower end, the binding force of the first spring 4 on the first dump bucket 1 is reduced, so that the first dump bucket 1 can freely turn at the lower end of the motion track. Similarly, the second tipping bucket 2 can be guaranteed to bear rainwater upwards at the high-end bucket opening of the movement track through the second spring 5, and the second tipping bucket 2 can freely turn over at the low-end of the movement track.
Specifically, in the present embodiment, when the first bucket 1 is at the top of the motion locus, the first spring 4 is vertically arranged to ensure that when the first bucket 1 is at the high end of the motion locus, the first spring 4 provides sufficient supporting force to prevent the first bucket 1 from overturning. Similarly, when the second dump bucket 2 is positioned at the top of the motion trail, the second spring 5 is vertically arranged.
