Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model The foundation of limitation.

Embodiment: a kind of ADCP multifunctional adapter, including data receiver platform 4, sensor module 6, information processing mould Block 1 and switch control module 5；

Referring in particular to Fig. 1.

Sensor module 6 can be temperature sensor, hydraulic pressure sensor or their combination, specifically can be according to actually making With being selected.

Message processing module 1 is mainly single-chip microcontroller, model are as follows: STM32F103ZET6 leads between single-chip microcontroller and sensor Cross the connection of RS422 interface.Conversion chip is set therebetween, the conversion chip be isolated RS422 chip 3 (model are as follows: ADM2587E).The circuit connection diagram of the chip is specifically as shown in Figure 2.

Data are passed to isolated RS422 chip 3 by sensor, are believed data by internal transformer after chip processing is good Breath is sent to single-chip microcontroller, since there is transformer in inside, it is possible to play the effect of isolation.

In addition, single-chip microcontroller can be embedded in different algorithm softwares, the initial data of sensor acquisition is connect by RS422 Mouth is given to single-chip microcontroller, and initial data is carried out data processing to single-chip microcontroller in house software and format is converted, and finally obtains user's needs Flow and flow rate.

Switch control module 5 is mainly made of switch chip U10, the model of switch chip are as follows: TPS22810.Switch chip Physical circuit connection as shown in figure 4, specifically, the 1st pin of switch chip U10 is connected to 12V voltage, switch chip U10's 3rd pin is connected to the first end of resistance R32, and the second end of resistance R32 is connected to message processing module 1, and the 2nd of switch chip U10 the Pin ground connection, the 4th pin of switch chip U10 are connected to the first end of capacitor C40, the second end ground connection of capacitor C40, switch chip The 5th pin of U10 is connected to the first end of resistance R33, the 6th pin of switch chip the U10 second end of connecting resistance R33,12V in succession Voltage and connector J12.The effect of switch chip is to control the on-off of probe power.

Specifically, after single-chip microcontroller detects that sensor upload has valid data, by switch chip U10 the biography The power supply of sensor disconnects.And make-and-break time node is set, and after specific time, power supply is again turned on, and actuated sensor issues simultaneously Upload valid data.(general flow velocity of river measurement is all that outdoors, power supply is typically all from solar cell for supplying power, institute It is relatively high with the requirement to power consumption, so being advantageous in that for the way saves unnecessary power loss, extend electricity The power-on time in pond guarantees the permanently effective work of whole system).

Data receiver platform 4, for detection data to be issued an order and received to single-chip microcontroller.

It is connected between single-chip microcontroller and data receiver platform 4 by RS232 interface, is turned likewise, being provided with therebetween Change chip --- isolated RS232 chip 2 (model are as follows: ADM3251E).Isolated RS232 chip 2 converts simultaneously for data Play the role of insulation blocking.

The utility model specific process in use in summary are as follows:

(1) system electrification, single-chip microcontroller can first open the power supply of sensor, then send work to sensor by serial ports and refer to It enables；

(2) sensor starts to carry out data acquisition after receiving instruction, and data are uploaded to single-chip microcontroller after acquisition completion；

(3) single-chip microcontroller receives sensor and uploads the data come up, and switch chip U10 turns off the power supply of sensor, allows and is System enters low-power consumption mode；

(4) single-chip microcontroller handles the data that sensor upload comes up by built-in algorithms of different software and carries out data Format conversion, the data through turning can be stored in inside E2PROM；

(5) switch chip is repeated (1)-(4) by the time-program(me) of setting；

(6) when single-chip microcontroller receives the instruction that platform issues, single-chip microcontroller can be by serial ports inside E2PROM Data are uploaded to platform.

It is noted that in specific implementation, the make-and-break time of probe power can be set according to the needs of users Fixed, for the place that power consumption requirements are very stringent, the time that can set power supply disconnection is a little long, and thus this low-power consumption is set Still very flexible.Such as the time of sensor acquisition needs 30s, and setting sensor power-off time is 270s, it is assumed that it is Power consumption when system work is 10W, and standby power consumption is 0.6W, then can calculate the average power consumption in 5 minutes is ((30S* 10W)+(270S*0.6W))/300S=1.54W.It can be seen, if system does not have low-power consumption mode, that function Consumption is 10W, and having added average power consumption after low power consumption control is 1.54W, this reduces about 6.5 times fully, is equivalent to making for battery 6.5 times are improved with the time.If also need to continue to improve battery uses the time, power-off time can accordingly be tuned up.
