300.At this point, the flow rate information is compared by controller 300 with its preset flow rate threshold.If flow rate information is in flow rate threshold
Interior, then controller 300 controls first switch device 210 and disconnects, and completes this time to monitor.If flow rate information not in flow rate threshold,
Then controller 300 controls second switch device 410 and is closed, at this point, first communication module 400 is powered on.Controller 300 can be with
Flow rate information and warning information are issued to first communication module 400.First communication module 400 turns flow rate information and warning information
It is changed to wireless signal, is launched.
After the wireless signal is received by the second communication module of monitoring device, second communication module can connect display mould
Block is shown by display module and artificial long-range monitoring can be realized.The monitoring device can be mobile phone, tablet computer, notebook
At least one of computer and PC.
Meanwhile flowmeter 200 can also be electrically connected with display 30, ought manually rush to where long-distance monitorng device 10
When ground, the display switch 34 of display 30 is opened, so that it may pass through the flow velocity of the water in display 30 intuitively observation water pipe 20.
In another embodiment, first communication module 400 can should also transmit control signal to controller 300, so that
After the artificial sending control signal by monitoring device, which is issued by second communication module, by first communication module 400
It receives.After first communication module 400 receives the control signal, it is transferred to controller 300, controller 300 can be according to control at this time
Signal processed executes order.The setting can remotely operate long-distance monitorng device 10, more convenient.
In a specific embodiment, substation's contour extraction, the controller 300 of long-distance monitorng device 10
It can be set to the flow velocity of the water of measurement in every 12 hours, the measurement duration is 5 minutes.In measurement process, first switch device
210 and second switch device 410 be closed, at this point, 10 total state of long-distance monitorng device run.Other times controller 300 controls
First switch device 210 and second switch device 410 disconnect, at this point, long-distance monitorng device 10 is standby.
By test, the discharge power of 24V DC power supply 100 can achieve 15748mAh, and discharge time-consuming about 16h.Remotely
10 total state stable operation electric current of monitoring device is 62mA to 64mA, standby mode stable operation electric current 12mA to 14mA.Therefore,
Under total state operation, long-distance monitorng device 10 can about work 10 days, under standby mode, can more work 54.5 days.
When setting long-distance monitorng device 10 every 12 is small, acquisition is primary, and when acquiring 5 minutes every time, battery can about run 50
It.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
