Description
Technical field
This utility model belongs to the hydrology, monitoring water environment technical field, is specifically related to a kind of water temperature detection device.
Background technology
In the current hydrology, monitoring water environment, in order to understand the water bodys such as lake, river, reservoir in zones of different, the distribution of water temperature situation of different depth, common technological means is to install temperature probe at zones of different, the different depth of water body.
As a example by reservoir vertical water temperature is monitored, in order to monitor the water temperature of different water depth in reservoir, it is usually and selects certain point in reservoir, 1m, 2m below this water surface, 3m ... place is respectively mounted temperature probe, multiple temperature probes are connected with data collecting instrument by a plurality of data lines.
There is following defect in water temperature detection scheme of the prior art:
1, poor reliability: after probe uses a period of time, be easily damaged or bigger error occurs, can only change.But the most not possessing maintenance condition due to scene, cause fault probe to change, there is disappearance in data；
2, probe weight is big, couples complexity, installs maintenance difficulties high.
Utility model content
Technical problem to be solved in the utility model is: proposes a kind of water temperature detection device, tip damage easily occurs or bigger error occur and install the problem that maintenance difficulties is high in solution tradition water temperature detection.
This utility model solves its technical problem and be the technical scheme is that
A kind of water temperature detection device, including data collecting instrument and at least one temperature probe, all temperature probes are connected in parallel in 1-wire bus, and connect data collecting instrument by described 1-wire bus；
Being provided with the digital temperature sensor of N number of support 1-wire bus in each described temperature probe, the corresponding function lead-out wire that the identical function pins in parallel of described N number of digital temperature sensor and is popped one's head in by place together is connected to 1-wire bus.
As optimizing further, described N=3.
As optimizing further, the digital temperature sensor in each described temperature probe is closely packed together, and and the shell of temperature probe between be filled with Heat Conduction Material.
As optimizing further, the shell of described temperature probe is the shell using corrosion-resistant thermal conductive metallic material to make.
As optimizing further, described corrosion-resistant thermal conductive metallic material is rustless steel.
The beneficial effects of the utility model are:
1, arranging the temperature sensor of multiple redundancy in a temperature probe, in normal conditions, all the sensors in a probe can gather data, so by asking each temperature data meansigma methods can improve monitoring accuracy；
2, in popping one's head in, certain temperature sensor occurs abnormal, can not use this sensor, and remaining sensor still can gather data, it is not necessary to changes probe, substantially increases reliability；
3, whole system uses 1-wire bus, and probe weight is little, simple in construction, and unified bus can be supported multiple probe.
Accompanying drawing explanation
Fig. 1 is the temperature probe structural representation in this utility model；
Fig. 2 is Multi probe parallel-connection structure schematic diagram.
Detailed description of the invention
This utility model is directed to a kind of water temperature detection device, tip damage easily occurs or bigger error occur and install the problem that maintenance difficulties is high in solution tradition water temperature detection.
Below in conjunction with the accompanying drawings and scheme of the present utility model is described in further detail by embodiment:
In this utility model, the structure to temperature probe has made improvement, temperature probe after improvement possesses redundant sensor structure, as shown in Figure 1, in probing shell 2, it is provided with multiple (being advisable for 3) supports the digital temperature sensor 1 of 1-wire bus, these temperature sensors 1 are closely packed together, being filled by Heat Conduction Material 3 between temperature sensor 1 and temperature probe shell 2, probing shell 2 uses corrosion-resistant thermal conductive metallic material (such as rustless steel) material to make.Additionally, the identical function pins in parallel of each temperature sensor 1 the corresponding function lead-out wire by probe are connected to 1-wire bus, it is internal that the data wire 4 in probe is positioned at probing shell 2, and the data wire 5 outside probe extends out from probing shell 2.
As described in Figure 2, the 1-wire bus in this utility model supports multiple probe, each probe is mounted with 3 sensors (sensor 3, as a example by DS18B20 for sensor 1, sensor 2).In each probe, the identical function pins in parallel of all the sensors together, probe lead-out wire only have 3, including power supply (VCC), data (DATA), (GND).
Owing to have employed 1-wire bus, the data of all the sensors only just can be read by a data lines.
It should be noted that; the water temperature detection device that this utility model is claimed includes but are not limited to the content of above-described embodiment; those skilled in the art improve/replace according to the record of above-described embodiment, equivalent done under connotation of the present utility model all without departing from protection domain of the present utility model.
