It is not as a limitation of the invention.
In embodiments of the present invention, there is provided a kind of weir measurement apparatus, the weir measurement apparatus amount of being arranged on
The top of mill weir, as shown in Figure 1, 2, the device include：
Stepper motor 101；
Ball screw 102, the first end of the ball screw 102 is connected with the rotor of stepper motor 101, in stepping
It is moved upwardly or downwardly under the drive of motor 101；

Connect, for touching the liquid level of liquid in the weir 100 just at the second end of the probe 104 and detecting electric current
When, send the trigger signal being stopped for triggering stepper motor；
Processor 106, it is connected with the stepper motor 101, for the trigger signal to be transmitted into the stepper motor
101, trigger the stepper motor 101 and be stopped；The second end of the probe 104 is calculated according to the step number of stepper motor 101
The first distance between the head high point of the weir 100, according to the head high point and water of the known weir 100
Second distance and first distance between head zero point, the liquid level of liquid in the weir 100 is calculated, according to described
The liquid level of liquid calculates seepage discharge in weir 100.
Understand as shown in Figure 1, in embodiments of the present invention, by stepper motor and ball screw drive probe upwards or to
Lower motion, realize the position of adjust automatically probe；It is lucky just at the second end of probe using the electric conductivity of electrode in a liquid
When touching the liquid level of liquid in weir, probe forms loop by the liquid in weir and electrode, now current sense
Device detects electric current, and triggering stepper motor is stopped so that the second end of probe has just touched liquid in weir just
Liquid level, now processor can be calculated according to the step number of stepper motor probe the second end and weir head high point it
Between the first distance, further according to the second distance and the first distance between the head high point and head zero point of known weir,
The liquid level of liquid in weir is calculated, and then seepage discharge is calculated according to the liquid level of liquid in weir, is realized
Can automatically, calculate seepage discharge in real time, compared with prior art, avoid data error existing for artificial observation method it is larger,
The problem of can not being measured in real time；And electrode and probe will not drift about, avoid weir self-operated measuring unit and use string wire
During formula instrument, existing easily generation drift, long-time stability are poor, are frequently necessary to the technical problem of manual synchronizing.The application provides
Weir measurement apparatus be advantageous to improve seepage flow measurement accuracy, be advantageous to simplify measurement operation.
When it is implemented, the second end and the weir 100 of probe 104 can be set in 101 no step number of stepper motor
Head high point be in same level, in order to directly calculate the second end of probe 104 according to the step number of stepper motor 101
The first distance between the head high point of weir 100, this is first apart from H1 as shown in Figure 2.
Specifically, the as shown in Fig. 2 actual weir slot that could be arranged to weir 100 of the head high point of weir 100
Summit, the head zero point of weir 100 actually can with the weir slot for being arranged to weir 100 bottom, i.e. weir
Second distance between 100 head high point and head zero point is H2 as shown in Figure 2.After measuring the first distance H1, by
The second distance H2 known subtracts the first distance H1, you can obtains the liquid level of liquid in weir 100, H as shown in Figure 2.
When it is implemented, in order to meet different measurement needs, in this application, above-mentioned weir measurement apparatus can adopt
With two kinds of measurement patterns, i.e., active measurement pattern with following measurement pattern automatically.Both of which can be by user according to live real
Border situation selection.
Specifically, the active measurement pattern that above-mentioned weir measurement apparatus is realized is, in the weir measurement apparatus not
When measuring (for example, when the closing of weir measurement apparatus or one-shot measurement terminate to stop measurement work), the probe 104
The head high point of second end and the weir 100 is in same level height；The processor 106, is additionally operable in the amount
Mill weir measurement apparatus starts (for example, the unlatching work of weir measurement apparatus, or processor and stepper motor start power up work
Make) after, the first trigger signal for triggering the stepper motor 101 and rotating forward directly is sent to the stepper motor 101, is driven
The probe 104 moves downward, until receiving the trigger signal that the current sensor 105 is sent, triggers the step
Stepper motor 101 is stopped.
I.e. under active measurement pattern, probe 104 is initially to stop at head high point, when measurement mill weir measurement apparatus is opened
Beginning after starting measurement, processor 106 directly controls stepper motor 101 to drive ball-screw rotation, moves down probe 104,
Until the second end of probe 104 just touches the liquid level of weir 100, processor 106 receives current sensor 105 and sent
Trigger signal, triggering stepper motor 101 is stopped, and then processor 106 calculates the according to the step number of stepper motor 101

During the length of pin 104, the first trigger signal for triggering the stepper motor 101 and rotating forward is sent to the stepper motor 101,
Drive the probe 104 to move downward, until receiving the trigger signal that the current sensor 105 is sent, trigger institute
Stepper motor 101 is stated to be stopped；When the distance is less than the length of the probe 104, sent to the stepper motor 101
Trigger the second trigger signal that the stepper motor 101 reversely rotates, drive the probe 104 to move upwards, until it is described away from
During from length equal to the probe 104, the trigger signal is sent to the stepper motor 101, triggers the stepper motor
101 are stopped.
I.e. it is automatic follow measurement pattern under, probe 104 coordinates infrared distance sensor 107 to use, and makes the of probe 104
Two ends follow the movement of liquid level and moved all the time, keep the second end of probe 104 just to touch liquid level all the time.Specific measurement
Method is to judge liquid level roughly using infrared distance sensor 107, that is, measures the second end of ball screw 102 to weir
The distance of the liquid level of liquid in 100, processor 106 again compare the distance and the length of probe 104, so as to determine probe
104 moving directions (rise or fall), for example, when distance is more than the length of probe 104, sends and trigger to stepper motor 101
The first trigger signal that stepper motor 101 rotates forward, the probe 104 is driven to move downward, until receiving current sense
The trigger signal that device 105 is sent, triggers the stepper motor 101 and is stopped, now the second end of probe 104 just connects
Contact liquid level；When distance is less than the length of probe 104, sends the triggering stepper motor 101 to stepper motor 101 and reversely revolve
The second trigger signal turned, drives the probe 104 to move upwards, until when the distance is equal to the length of the probe 104,
The trigger signal is sent to the stepper motor 101, the stepper motor 101 is triggered and is stopped, now the of probe 104
Two ends also just touch liquid level.So that the second end of probe 104, which remains at, just touches liquid level in weir 100
Position, and then processor 106 calculates the first distance according to the step number of stepper motor 101, further according to known second distance meter
Calculate the liquid level (H) of weir 100.
