Description

A kind of hydrology measure and control device
Technical field
The utility model belongs to hydrographic water resource monitoring field, specifically a kind of hydrology measure and control device.
Background technology
RTU(Remote Terminal Unit, the remote terminal measurement and control unit) be the equipment that can finish collection, storage, transmission and the control of the hydrology (regimen, water resource) parameter automatically.RTU is as such intelligent monitoring terminal, the polytype sensor of need plugging into, and these sensors need external power source mostly.And the sensor of some type such as photo-electronic directly reading water meter do not need full-time power supply, and power supply in real time gets final product when only needing RTU to communicate with.Yet present RTU can not realize controlling in real time the function of sensor power supply, so can only give the full-time power supply of such sensor.The mode of this full-time power supply is unfavorable for energy savings, if the employing storage battery power supply has also shortened the power supply duration of accumulator, influences the serviceable life of accumulator; In addition, because the aging of sensor also accelerated in charged work always, shortened the serviceable life of sensor.
The utility model content
At above-mentioned deficiency, the utility model provides a kind of hydrology measure and control device of controlling the sensor power supply by RTU in real time.
The technical scheme in the invention for solving the technical problem is: a kind of hydrology measure and control device, comprise RTU, sensor and sensor supply module, it is characterized in that, also comprise gauge tap, described RTU comprises MCU and communication module, and described MCU is connected with communication module, and described sensor is connected with the sensor supply module with communication module respectively, described gauge tap is arranged in the circuit between sensor supply module and the sensor, and the control end of gauge tap is connected with MCU.
Further, also comprise connection terminal, described connection terminal is arranged in the circuit between sensor and communication module and the sensor supply module.
Further, described gauge tap comprises relay, and the normal open switch of described relay is connected in the circuit between sensor supply module and the sensor, the coil one end ground connection of relay, and the other end is connected with the GPIO end of MCU.
The beneficial effects of the utility model are: the utility model is by increasing the break-make that relay is controlled the sensor current supply circuit in sensor feed circuit, the action of relay is controlled by the MCU of RTU; When RTU need be with sensor communication, the normal open switch closure of the GPIO end pilot relay by MCU was powered to sensor, after communication is finished, the normal open switch of pilot relay disconnects, and comes to the sensor outage, thereby reaches the purpose that real-time control sensor is powered.The utility model has been avoided unnecessary power consumption, and energy savings has been avoided the unnecessary discharge of accumulator, has prolonged the power supply duration of accumulator, has prolonged the serviceable life of sensor to a certain extent.

Among the figure, 1MCU, 2 communication modules, 3 sensors, 4 sensor supply modules, 5 relays, 6 connection terminals.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of hydrology measure and control device of the present utility model, it comprises RTU, sensor 3, sensor supply module 4, gauge tap and connection terminal 6, described RTU comprises MCU1 and communication module 2, described MCU1 is connected with communication module 2, described sensor 3 is connected with sensor supply module 4 with communication module 2 respectively, described gauge tap comprises relay 5, the normal open switch of described relay 5 is connected in the circuit between sensor supply module 4 and the sensor 3, the coil one end ground connection of relay 5, the other end is connected with the GPIO end of MCU1; Described connection terminal 6 is arranged in the circuit between sensor 3 and communication module 2 and the sensor supply module 4.
Fig. 2 is circuit diagram of the present utility model.As shown in Figure 2, the MCU1 of described RTU selects the LM3S1968 of TI company for use, and PA1 is its GPIO port, uses as control end, and TX, RX are respectively transmitting terminal and the receiving ends of its UART Universal Asynchronous Receiver Transmitter, and link to each other with the communication module 2 of RTU; Described gauge tap selects for use relay 5 as the switch of the break-make of the current supply circuit of control sensor 3, the end of the coil J of relay 5 is connected with the PA1 of MCU1 end, other end ground connection, normal open switch JK is connected in the circuit between sensor supply module 4 and the sensor 3; Described communication module 2 is connected with the communication terminal of sensor 3 by A, the B terminals of connection terminal 6 respectively, and the power input of described sensor 3 is connected with sensor supply module 4 with the normal open switch of relay 5 with the PW2 terminals by the PW1 of connection terminal 6 respectively; The normal open switch JK of described sensor supply module 4, relay 5, PW1, the PW2 of connection terminal 6 constitute the current supply circuit of sensor 3.
This hydrology measure and control device course of work is as follows: (when RTU does not communicate by letter with sensor 3) at ordinary times, the PA1 output low level of MCU1, relay 5 is not worked, and normal open switch JK is in off-state, the current supply circuit open circuit of sensor 3, sensor 3 outages are not worked.When RTU need communicate by letter with sensor 3, the PA1 of MCU1 exported high level, relay 5 work, and normal open switch JK closure, the current supply circuit conducting of sensor 3 makes its work for sensor 3 power supplies.Behind the sign off, the PA1 output low level of MCU1, the current supply circuit open circuit of sensor 3, sensor 3 outages quit work.Reach sensor 3 outages at ordinary times, the purpose of powering in real time when RTU need communicate with.
Except structure described in the utility model, all the other are prior art.
The above is preferred implementation of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also are regarded as protection domain of the present utility model.
