Common mechanical electronic scales remote control function

Floor scale adjustment changes the output voltage. The output voltage fluctuates every change in resistance. An additional feature that is tight is that when there is no load, the main power supply will be turned off after the delay in the power supply period. This feature consists of a tube with three electrodes, a weighbridge remote and diode, and a capacitor. When the load is working properly, there is a voltage drop on the diode, and the ground scale remote control reaches the high conduction of the Zui. The relay is powered by the office, and the normally open contact is closed to ensure that the power supply circuit is normally powered. At the same time, the capacitor is charged to 3~4 volts.

When the load breaks, it ends at this time, but because of the discharge effect, it will continue to maintain the conduction appearance. With the advancement of technology, the precision level requirements for the Bianbo scale remote control and the floor scale products are getting higher and higher, and the precision of the push-pound parts processing is constantly increasing. The weighbridge remote controller has a lot of carrier signals of various frequencies in the sky, and selects the required signals from a plurality of carrier signals to suppress the interference signals. This is the main role of the receiving module tuning the frequency selection part. Amplification due to the attenuation characteristics of the channel, the quality of the floor scale: the previous method of alignment without using the automatic alignment tool is mainly based on visual inspection, that is, the employee uses the visual inspection of the indenter on the product and the indenter on the standard sensor of the machine. Position adjustment, this method causes the position of the alignment to be easily offset, and the test data is inaccurate. After the automatic alignment tooling is used, the employee only needs to put the required test product into or close to the standard position of the tooling during the operation. The alignment position is completely and accurately matched, which ensures the uniformity and accuracy of the test data. The signal level reaching the receiving end after long-distance transmission is very weak. In order to improve the sensitivity of the receiving module, it is necessary to perform signal amplification before the detector to obtain sufficient The energy is detected. The basic structure of the weighbridge remote control electronic scale is generally two.

One is a foundation pit with an electronic balance installed above the ground level; the other is a shallow foundation pit installed below the ground plane. The construction of the foundation embedded parts must be carried out to ensure the exact position for the installation of the scale body. For this reason, it is recommended to use the secondary watering side limiting baffle. The horizontality and elevation error between the bearing plates must conform to the basic design requirements. The deviation should be less than 3mm. The platform space at both ends of the scale should be rectangular instead of Parallelograms, so the measured diagonals should be equal after construction is completed. After the construction of the concrete foundation, attention must be paid to the protection. The general basic curing period is 28 days.

In order to shorten the construction period and curing time, it is allowed to add “early strengthening agent” and other measures to the concrete during construction. The concrete does not reach the video communication category; such products are more common in multi-layer boards, because such boards must be specific to film and television, sound and Operational and other functions, so the line direction is more complicated, and this type of product advocates that it is light, so the volume is relatively small, the function is relatively strong, the requirements for the scale remote control are relatively high, and the line direction is very precise.
