Abstract
The utility model relates to an electronic proportioning scale comprising a main control module, a motor driving module, a weighing sensing module, and a communication module. The electronic proportioning scale is characterized in that the main control module is respectively connected with the motor driving module, the weighing sensing module, and the communication module. An upper computer arranges the weights of various ingredients and uses the communication module to transmit the weight information to the main control module. When one positioning process begins, the main control module controls the motor driving module to open an electrically operated valve and a feed bin starts to carry out laying off; meanwhile, the weighing sensing module collects a signal of a weighing sensor on a hopper scale; the collected signal information is compared with a corresponding proportioning preset weight and when the preset weight is reached, the motor driving module closes the electrically operated valve. The same operation is repeated at the next channel; and after all the laying off of all the channels is completed, the proportioning operation is transferred and the proportioning next time starts.
Description
Technical field
The utility model relates to a kind of burden balance, especially electronic batching scale.
Background technology
Burden process is an important step in the industrial and agricultural productions such as cement, chemical industry, food, building materials, also is the source operation of producing, and the quantitative weighing feed proportioning system also is widely used in the production run of various one-tenth bag package metro-measurings simultaneously.Traditional quantitative weighing mode can not satisfy the requirement of the measuring accuracy and the work efficiency in many fields.
Summary of the invention
In view of above reason, the utility model provides a kind of electronic batching scale.Be based on the intelligent device of microcomputer development, not only can be used for industrial quantitative weighing and also can be used for the industry batching.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of electronic batching scale, comprise main control module, motor drive module, weighing and sensing module, communication module, it is characterized in that the main control module is connected with motor drive module, weighing and sensing module, communication module respectively.Host computer is provided with the weight of various batchings, is sent to the main control module by the communication module.When one time blending process began, main control module controls motor drive module was opened motorized valve, the blanking of beginning feed bin, the weighing and sensing module is gathered load cell signal on the bunker scale simultaneously, compare with corresponding batching preset weight, when reaching preset weight, motor drive module is closed motorized valve.Next passage repeats same operation, finishes until all passage blankings, and this time batching is shifted, and beginning is batching next time.
The beneficial effects of the utility model are, are applicable to various working environments, not only can be used for industrial quantitative weighing and also can be used for the industry batching, have advantages of high practicability.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
In Fig. 1, a kind of electronic batching scale comprises main control module 1, motor drive module 2, weighing and sensing module 3, communication module 4, it is characterized in that, main control module 1 is connected with motor drive module 2, weighing and sensing module 3, communication module 4 respectively.Host computer is provided with the weight of various batchings, is sent to main control module 1 by communication module 4.When one time blending process begins, main control module 1 control motor drive module 2 is opened motorized valve, the blanking of beginning feed bin, weighing and sensing module 3 is gathered load cell signal on the bunker scale simultaneously, compare with corresponding batching preset weight, when reaching preset weight, motor drive module 2 is closed motorized valve.Next passage repeats same operation, finishes until all passage blankings, and this time batching is shifted, and beginning is batching next time.
Main control module 1 is selected the MC9S08AW60 single-chip microcomputer for use, be one of 08 series of products of Freescale, it can be used in all kinds of rugged surroundings for the highly reliable Electro Magnetic Compatibility EMC of MC9S08AW60 and EDC, and the Applicable temperature wide range is applicable to various working environments.Motor drive module 2 adopts L6208, two full-bridges that this chip is integrated is made up of 8 power DMOS transistors, the centralized logical circuit and the constant pulse width modulation electrical current controller of turn-off time of an excute phase systematic function, this chip ENABLE is the enable signal of L6208, enables work during high level.CW/CCW is used for turning to of control step motor, and during high level, motor just changes; During low level, the motor counter-rotating.The CLOCK rising edge triggers effectively, can come the frequency of the stepped sequence of control phase sequencer generation by the frequency of adjusting the CLOCK pulse, to realize the control to stepper motor speed.When RST is low level, the initialization of phase sequence generator.HALF/FULL_ is used for being provided with the pattern of stepped sequence, can be set to half step mode, single-phase full step mode and the full step mode of two-phase etc.Weighing and sensing module 3 is four groups of parallel resistor strain gauge load cells, because strain-gauge transducer is output as the mV signal, and after instrument amplifier amplifies, input A/D conversion chip.Communication module 4 adopts the RS232/TTL level shifting circuit, the preset weight of will preparing burden sends single-chip microcomputer from PC to by LabVIEW, because the level standard of PC RS232 serial ports and the TTL level of single-chip microcomputer are inconsistent, so the serial communication between single-chip microcomputer and the PC must adopt the RS232/TTL level shifting circuit.
