Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1.There is provided a kind of highly automated measurement of Weight type green coke of microprocessor control in the embodiment of the present invention
Device, it is made up of detector and controller two parts.Explorer portion is the mechanical part of whole detecting system, including is installed
In the motor on shell body 2, active line wheel 1, movable pulley 10 and fixed pulley 3, active line wheel 1 and motor connection, in active line wheel 1
Pull rope 4 bypass movable pulley 10 and fixed pulley 3 after be connected with weight 7.Movable pulley 10 is provided with chute 8, and movable pulley 10 passes through
Chute 8, which is sleeved on, to be fixed on the slide bar on shell body 2.The weight of movable pulley 10 is less than 2 times of the weight of weight 7, so dynamic slide
The axle of wheel 10 is pushed to the top of chute 8.
Controller part is the field controlling instrument using microcontroller as core, mainly realizes detection, the motor of thing position
Control, the display and transmission of information.Finally, measurement result is converted to 4mA~20mA DC signal outputs of standard.Controller
Part, which is included, to be fixed on shell body 2, and the first proximity switch with movable pulley 10, fixed pulley 3 and the corresponding matching of weight 7 respectively
A9, the second proximity switch B5 and the 3rd proximity switch C6.First proximity switch A9 is arranged on movable pulley 10 and slides top, and first connects
Nearly switch A9 is not triggered when the axle of movable pulley 10 falls below chute 8, when the axle of movable pulley 10 is pushed to the top of chute 8,
First proximity switch A9 is triggered, and detects whether weight 7 contacts tested object plane with this.On fixed pulley 3 circumference uniform distribution install 4 or
Multiple metal bosses, the second proximity switch B5 is arranged on the side of fixed pulley 3, and when fixed pulley 3 is rotated, each boss is close to second
Exploitation is triggered during proximity switch B5, output of pulse signal is produced, the liter of weight 7 can be obtained by the processing of pulse signals pair
Height value drops.3rd proximity switch C6 is installed on the frame bottom of fixed pulley 3, is approached when weight 7 is pulled to top triggering the 3rd
When switching C6, motor stops lifting weight 7, while being reset to counting, it is to avoid measurement produces cumulative errors.Controller part includes
Microprocessor and the isolation circuit being connected with microprocessor, motor-drive circuit, power circuit, button display circuit and communication electricity
Road.Isolation circuit is connected with the first proximity switch A9, the second proximity switch B5 and the 3rd proximity switch C6.Motor-drive circuit with
Motor connection.Communicating circuit is remotely obtained comprising ModBus bus communications there is provided the mode of ModBus bus communications.Pass through micro- place
Manage device controlled motor and rotate release pull rope 4, pull rope 4 bypasses a movable pulley 10 that can be slided in chute 8, further around mistake
One fixed pulley 3, and tensioning is drawn by a weight 7.During release, weight 7 is tensioned pull rope 4 all the time, and drive is fixed
Pulley 3 is rotated.The displacement of the lines of the outer ring of fixed pulley 3 is equal with the displacement of weight 7 all the time.
The mass of weight 7 is primarily due to more than movable pulley 10, movable pulley 10 is located at sliding bar top, switch connection, weight 7
In Ta Kou, when sending sign on, motor is rotated forward, weight drop, start recording pulse, until weight 7 drops down onto measured solid
On, now movable pulley 10 falls on sliding bar bottom, and triggers circuit, stop recording pulse exports high by calculating by display screen
Degree, and motor starts reversion withdrawal weight, when weight 7 is received to tower mouthful, reaches upper bound trigger switch, motor stalling.
