Description

Energy-saving telemetering terminal

Technical field

The present invention relates to the telemetering terminal field, be specifically related to energy-saving telemetering terminal.

Background technology

Telemetering terminal is exclusively used in water conservancy monitoring and geology monitoring, realizes sensing data is gathered, and is uploaded to by various communication networking models and compiles central station, and central station carries out Warning Service with carry out the model calculation according to the data of compiling.Central station can carry out long-range trick survey, Remote configuration, remote maintenance to remote terminal.Telemetry terminal system is being brought into play important effect in observation process.In addition, the telemetering terminal that is used for water conservancy monitoring and geology monitoring field need to be in high humility, high rainwater, and high temperature tans by the sun, long-term work under the high and cold environment that freezes.We often need to detect the voltage of telemetry terminal system, and the voltage range of telemetering terminal changes greatly, need to consume larger electric weight and detect the used sensor of larger voltage, but hour then use the less sensor of sensing range just can reach needs for detecting voltage.How when reaching large-scale detection voltage, can also accomplish that energy-conservation effect is the direction that we make great efforts.

Summary of the invention

The present invention has overcome the deficiencies in the prior art, and energy-saving telemetering terminal is provided, and uses by two sensor segmentations, realizes energy-conservation under large sensing range.

For solving above-mentioned technical matters, the present invention is by the following technical solutions: energy-saving telemetering terminal, comprise probe power, first sensor, the second sensor, telemetry terminal system and single-pole double-throw switch (SPDT), described probe power connects A end, first sensor and second sensor of single-pole double-throw switch (SPDT) simultaneously; Described telemetry terminal system connects first sensor and the second sensor simultaneously; Described first sensor also is connected to the B end of single-pole double-throw switch (SPDT), and the second sensor also connects the C end of single-pole double-throw switch (SPDT).

Described telemetry terminal system comprises central processing unit, RTC real-time clock, FLASH storer and wireless network card, and RTC real-time clock wherein, FLASH storer and wireless network card all are connected on the central processing unit, also is connected with antenna on the wireless network card.

Described RTC real-time clock model is DS1302.

Embodiment

The present invention is further elaborated below in conjunction with accompanying drawing, and embodiments of the invention are not limited to this.

Embodiment:

As shown in Figure 1, the present invention includes probe power, first sensor, the second sensor, telemetry terminal system and single-pole double-throw switch (SPDT), telemetry terminal system comprises central processing unit, RTC real-time clock, FLASH storer and wireless network card, RTC real-time clock wherein, FLASH storer and wireless network card all are connected on the central processing unit, also are connected with antenna on the wireless network card.RTC real-time clock model wherein is DS1302, and the model of central processing unit is LX4F232H5QCFIGA3, and the model of wireless network card is WL-167G.The probe power of the present embodiment connects A end, first sensor and second sensor of single-pole double-throw switch (SPDT) simultaneously, the telemetry terminal system of the present embodiment connects first sensor and the second sensor simultaneously, first sensor wherein also is connected to the B end of single-pole double-throw switch (SPDT), and the second sensor also connects the C end of single-pole double-throw switch (SPDT).First sensor wherein detects the scope of voltage between 0-8V, and the second sensor detects the scope of voltage between 7-15V.

The scope that first sensor detects voltage is 0 to 8V, the scope that the second sensor detects voltage is 7-15V, because the sensing range of the second sensor is higher, power consumption is larger, therefore in low voltage range, single-pole double-throw switch (SPDT) control probe power is powered to first sensor, when first sensor detects 7V when above, output signal control single-pole double-throw switch (SPDT) turns to the power supply of the second sensor, finishes sensing range more than the 7V by the second sensor.Use by two sensor segmentations, realize energy-conservation under large sensing range.

Just can realize this invention as mentioned above.
