The wireless meter reading node of the water meter has the advantages of simple structure, low energy consumption and high reliability.
Description
Technical field
The utility model relates to a kind of node of checking meter, and relates to a kind of water meter radio meter register node in particular.
Background technology
The state that present wireless self-networking water meter kilowatt meter reading-out system needs node to be in and wakes up and be waken up carries out work, present node switches between waking up and be waken up through being everlasting, so its energy consumption is bigger, usually can not take into account the energy consumption of waking and be waken up two states up, be prone to communication failure, communication reliability reduces.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of water meter radio meter register node is provided, and node energy consumption was big in the past for solving, the problem that communication reliability is relatively poor.
For solving above-mentioned technical matters, the utility model is by the following technical solutions: a kind of water meter radio meter register node, comprise power management chip, real-time clock module, microprocessor, data converter and wireless communication module, described real-time clock module all is connected with microprocessor with data converter, described wireless communication module is connected with data converter, and described real-time clock module, microprocessor, data converter and wireless communication module all are connected with power management chip.Real-time clock module has the real-time time update functions, can set wakeup time to it, power supply is in off-position under the power management chip effect when off working state, when wakeup time then, thereby real-time clock module sends a signal to power management chip and wakes power supply up and enter duty, save power consumption, thereby realize the low-power consumption function, make node can satisfy the conversion that wakes up with dormant state.
Described microprocessor is MSP430 type microprocessor.The MSP430 microprocessor has low in power consumption, has wakeup time, low-power consumption oscillator and reservoir designs faster.Micro-control unit adopts MSP430 type microprocessor can reduce power consumption greatly, and travelling speed is fast.
Described power management chip is HIP6301 type power management chip.Not only price is low for HIP6301 type power supply control chip, stable performance, and volume is little, and multiple functional, can reduce cost when guaranteeing power management.
Described wireless communication module adopts WAP300C type wireless module.WAP300C type wireless module has 64 channels, can revise channel, baud rate and emissive power, and communication distance is far away, and cost is low, and less energy consumption.
Described microprocessor is provided with USB interface, RS-232-C serial line interface, RS-422 serial line interface and RS-485 serial line interface.For convenient for maintaining, upload data, download data and debugging, microprocessor is established USB interface, RS-232-C serial line interface, RS-422 serial line interface and RS-485 serial line interface, is used for connecting external equipment.
Compared with prior art, the beneficial effects of the utility model are: this water meter radio meter register node of the utility model design, and not only simple in structure, and also less energy consumption, good reliability.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is principle schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Embodiment of the present utility model includes but not limited to the following example.
Embodiment
A kind of water meter radio meter register node as shown in Figure 1, comprise power management chip, real-time clock module, microprocessor, data converter and wireless communication module, described real-time clock module all is connected with microprocessor with data converter, described wireless communication module is connected with data converter, and described real-time clock module, microprocessor, data converter and wireless communication module all are connected with power management chip.
Described microprocessor is MSP430 type microprocessor.
Described power management chip is HIP6301 type power management chip.
Described wireless communication module adopts WAP300C type wireless module.
Described microprocessor is provided with USB interface, RS-232-C serial line interface, RS-422 serial line interface and RS-485 serial line interface.
Real-time clock module of the present utility model is set with wakeup time, when off working state, power management chip is with microprocessor, the power supply of data converter and wireless communication module disconnects, when wakeup time then, real-time clock module transmits a signal to power management chip, power management chip control power supply and microprocessor, data converter and wireless communication module connect energising, wireless communication module receives signal by wireless network, execution command also sends information needed, finish the work, the back real-time clock module of finishing the work sends a signal to power management chip off device power supply, enters dormant state again.
Be embodiment of the present utility model as mentioned above.The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
