Abstract

The invention discloses a multifunctional wiring terminal integrating telemetering and telesignalling acquisition. The multifunctional wiring terminal comprises a first telesignalling wiring terminal; a second telesignalling wiring terminal; a voltage conversion circuit which is arranged on the second telesignalling wiring terminal, wherein the positive electrode input end of the voltage conversion circuit is electrically connected with the positive electrode wire pressing frame of the first telesignalling wiring terminal, and the negative electrode input end of the voltage conversion circuit is electrically connected with the negative electrode wire pressing frame of the first telesignalling wiring terminal, the positive electrode output end of the voltage conversion circuit is electrically connected with the positive electrode wire pressing frame of the second telesignalling wiring terminal, and the negative electrode output end of the voltage conversion circuit is electrically connected with the negative electrode wire pressing frame of the second telesignalling wiring terminal, wherein the second telesignalling wiring terminal is fixedly connected to the first telesignalling wiring terminal through a bolt. The problems that in the prior art, telesignalling and telemetering signals cannot be collected at the same time, telemetering collected semaphores cannot be directly connected to a measurement and control direct current board, cost is high, maintenance workload is large, and installation is difficult are solved.

Description

technical field [0001] The invention relates to a multifunctional connection terminal integrating remote measurement and remote signal collection, belonging to the technical field of remote signal and telemetry. Background technique [0002] At present, the terminals used in the collection of remote signaling signals and telemetry signals on the market are all independent terminals. And the telemetry acquisition terminal has no signal conversion method, so it cannot realize small current (such as 4-20mA) or small voltage (0-5V) output. For the general measurement and control device DC board (current type: 4-20mA, voltage type: 0-5V ), the signal volume collected by telemetry (generally the secondary voltage of the voltage transformer or the secondary current of the current transformer) cannot be directly connected to the DC board of the measurement and control device. [0003] The problem caused by this is that if the existing technology collects the analog quantity of a ce...

Problems solved by technology

And the telemetry acquisition terminal has no signal conversion method, so it cannot realize small current (such as 4-20mA) or small voltage (0-5V) output. For the general measurement and control device DC board (current type: 4-20mA, voltage type: 0-5V ), the signal volume collected by telemetry (generally the secondary voltage of the voltage transformer or the secondary current of the current transformer) cannot be directly connected to the DC board of the measurement and control device

[0003] The problem caused by this is that if the existing technology collects the analog quantity of a certain remote signaling circuit, it can be realized by using an independent DC transmitter, etc., but there are many problems as follows: one DC transmitter is required for the acquisition object , greatly increasing the cost; the guarantee and maintenance workload of the DC transmitter operation reliability increased; the difficulty of on-site installation and other problems
