Problems solved by technology

[0002] At present, the construction site information transmission system mainly includes the control terminal, the Internet of Things, and the construction site information acquisition module. Wireless transmission will cause the signal to be magnetized by the city's high-voltage lines, which will cause the signal to be distorted by the strong magnetic magnetization, resulting in inaccurate information transmission on the construction site

Abstract

The invention discloses a construction site information transmission system. The system comprises a frequency acquisition circuit, a feedback adjustment circuit, a reference circuit and a filter output circuit. The frequency acquisition circuit collects a simulation signal frequency in an output signal of a site information acquisition module, and the feedback adjustment circuit uses an operationamplifier AR4, a triode Q5, and a triode Q6 to form a composite circuit to detect an in-phase input end signal of a comparator AR5. The triode Q5 feeds back a high-level signal into an in-phase inputend of an operation amplifier AR1, and the triode Q6 feeds back a low level to an inverting input end of an operation amplifier AR3, wherein the inverting input ends of a comparator AR2 and a comparator AR5 receive a reference circuit output signal. A reference circuit uses a variable resistor R7 to regulate a power supply +5V output signal voltage, and finally an output signal of the comparator AR5 is input into the filter output circuit. The filter output circuit uses a voltage regulator tube D6 to carry out voltage stabilization, and a resistor R13 and a capacitor C9 are filtered and then are used to control a correction signal of a terminal simulation signal so as to improve accuracy of construction site information transmission.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to a construction site information transmission system. Background technique [0002] At present, the construction site information transmission system mainly includes the control terminal, the Internet of Things, and the construction site information acquisition module. Wireless transmission will cause the signal to be magnetized by the city's high-voltage lines, which will cause the signal to be distorted due to the strong magnetic magnetization, resulting in inaccurate information transmission on the construction site. Contents of the invention [0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a construction site information transmission system, which has the characteristics of ingenious conception and humanized design, and can detect the data information output by the construction sit...
