Embodiment Construction

[0012] Such as Figure 1-2 As shown, the automatic upper and lower limit electronic scale device described in the embodiment of the present invention includes an integrated control unit 3 and an electronic scale part 4, and the external sides of the electronic scale part 4 are respectively connected to a relay unit one 1 and a relay unit two 2. The relay unit one 1 and the relay unit two 2 are respectively connected with the lower limit control module 6 and the upper limit control module 5 in turn, so as to realize the control when the material conveyed by the feeder reaches the upper and lower limit set weights. The lower limit control module 6 and the upper limit control module The modules 5 are all connected to the alarm prompt module, and at the same time, an integrated control unit 3 is added inside the said electronic scale part 4, and each output terminal outside the integrated control unit 3 is respectively connected with the power indicating terminal, the vibration mod...

Abstract

The invention relates to an electronic balance device capable of automatically limiting in an upper-and-lower mode. The electronic balance device capable of automatically limiting in the upper-and-lower mode comprises an integrated control unit and an electronic balance part. A first relay unit and a second relay unit are connected to two outer sides of the electronic balance part respectively. The first relay unit and the second relay unit are respectively and sequentially connected with a lower limit control module and an upper limit control module. The lower limit control module and the upper limit control module are connected with an alarming prompt module. Meanwhile, the integrated control unit is additionally arranged in the electronic balance part. The electronic balance device capable of automatically limiting in the upper-and-lower mode has the advantages that when materials conveyed by a material conveyor reach the set weight of the electronic balance, the device alarms and meanwhile, a conveyor belt slows down and the upper limit stop precision can reach four thousandths.

Description

technical field [0001] The invention relates to an automatic upper and lower limit electronic scale device. Background technique [0002] The working principle of the electronic scale is composed of electronic components: weighing sensor, amplifier circuit, AD conversion circuit, single-chip microcomputer circuit, display circuit, keyboard circuit, communication interface circuit, regulated power supply circuit and other circuits. Its working process is generally that when the object is placed on the weighing pan, the pressure is applied to the sensor, and the sensor is deformed, so that the impedance changes, and at the same time, the excitation voltage is used to change, and a changed analog signal is output, which is amplified by the amplifier circuit. Output to the analog-to-digital converter, convert it into a digital signal that is easy to process and output it to the CPU operation control, and the CPU outputs the result to the display according to the keyboard comman...
