Problems solved by technology

[0004] 1) It only has the function of signal acquisition, and cannot directly calculate the weight value and output the weight value or weighing internal code value. Therefore, it is not friendly to the developer of the weighing software system, and the developer of the weighing software needs to master the relevant professional knowledge of weighing instruments and Algorithm and function development experience;
[0005] 2) It is necessary to manually adjust the adjustable resistance value inside the device to realize sensor angle adjustment, balance adjustment, and signal error adjustment between sensors. The physical adjustment method of resistance is not intuitive, time-consuming, and labor-intensive, and requires professionals. operate;
[0006] 3) You can only process and view the calculated weighing value through the host computer, and cannot query the weighing internal code value of each sensor;
[0007] 4) When a certain sensor fails, it is impossible to automatically detect which of the connected sensors is abnormal, it needs to rely on manual judgment, and professionals with certain experience are required to diagnose the problematic sensor, which is time-consuming and laborious ;
[0008] 5) After the sensor is abnormal, the weighing weight has a great deviation, and the weighing system cannot be used;
[0009] 6) For the sensor that has been connected to the junction box, it cannot be shielded flexibly. If it is not used, it must be removed, otherwise it will also cause an error in weighing;
[0010] 7) After replacing the upper computer, the new upper computer needs to manually reset the model data and re-calibrate the operation;
[0011] 8) The junction box can only be connected to the host computer by cable, and the sensor digital signal transmission is performed between the host computer and the construction wiring flexibility is poor

Abstract

The invention relates to a digital sensor junction box which comprises a main board and at least one analog-to-digital conversion board, wherein a first main control unit and a first communication module which are in communication connection with each other are welded on the main board, a second main control unit and a second communication module which are in communication connection with each other are welded on each analog-to-digital conversion board, the first communication module is respectively in communication connection with an upper computer, a mobile terminal and the second communication module, the second main control unit is further in communication connection with external sensors in a one-to-one correspondence manner, a unique address code is stored in the second main control unit, and the first main control unit accesses the specified second main control unit according to the address code. The invention further relates to a weighing system based on the digital sensor junction box, which sets functions and parameters of the junction box through using a weighing parameter adjusting APP on the mobile terminal, and the junction box can process signals collected by the sensor, convert the signals into weight values, store the weight values and output the weight values to the upper computer. The digital sensor junction box and the weighing system have the advantages of excellent usability, portability and expandability.

Description

Technical field [0001] The present invention relates to digital sensor junction box and the weighing system of the junction box based on belonging to said electronic field. Background technique [0002] Traditional digital signal acquisition sensor junction box by a plurality of sets of terminals, adjustable resistance, digital to analog conversion module. The junction box is connected by a signal line composed of the load cell weighing platform digital sensor, an analog signal of the sensor output acquisition junction box, and the analog signal into a digital signal, the digital signal read by the user PC system, the PC calculation processing system to be implemented various weighing operations, the digital signal parameters. [0003] There is a problem with the connection box weighing system: [0004] 1) only has signal acquisition function, and can not calculate the weight values ​​directly and output weight values ​​or weighed in the code value, therefore, the weighing softwa...
