Comprehensive data communication line of meter reading device

Abstract

The invention provides a comprehensive data communication line of a meter reading device. The comprehensive data communication line comprises a first interface line, a second interface line, a quick-change connector and a connector clamping mechanism, wherein the quick-change connector comprises a first adapter and a second adapter; the first adapter and the second adapter are in contact connection through transmission panels on respective free end surfaces to transmit electric energy and data; the first adapter comprises a power receiving coil, a metal piece and a first core plate; the powerreceiving coil is horizontally laid at an inner side of the transmission panel of the first adapter; an end surface of the metal piece is coplanar with the transmission panel of the first adapter; themetal piece sleeves an outer edge of the transmission panel of the first adapter; the second adapter comprises a power transmission coil, a magnetic piece and a second core plate; the power transmission coil is horizontally laid at an inner side of the transmission panel of the second adapter; an end surface of the magnetic piece is coplanar with the transmission panel of the second adapter; andthe magnetic piece sleeves an outer edge of the transmission panel of the second adapter. By the comprehensive data communication line, the plug-pull frequency of the connector can be remarkably reduced, the connection operation of a cable is easy to implement, the connection is reliable, and the connection stability of the data transmission process of two devices is ensured.

Description

technical field [0001] The invention relates to the technical field of data lines, in particular to a comprehensive data communication line for meter reading devices. Background technique [0002] During the debugging or timing process of heat metering, cold metering, electricity metering and other data collectors, operation and maintenance personnel are required to connect the computer and collectors through communication cables on site. There are two problems in the existing technology, one is: different metering requirements have different metering communication protocols, and different protocols often use different physical interfaces. Therefore, engineering operation and maintenance personnel need to carry a variety of different interface Connect cables to adapt to the communication ports of the equipment at both ends. The second is that the outdoor environment is different from the laboratory. Due to weather, man-made, and multiple plugging and unplugging, the connecti...

Problems solved by technology

There are two problems in the existing technology, one is: different metering requirements have different metering communication protocols, and different protocols often use different physical interfaces. Therefore, engineering operation and maintenance personnel need to carry a variety of different interface Connect cables to adapt to the communication ports of the equipment at both ends. The second is that the outdoor environment is different from the laboratory. Due to weather, man-made, and multiple plugging and unplugging, the connection reliability between cables is insufficient, and the connection is prone to loosening. , poor contact or external force disconnection, etc., the rate and integrity of data transmission cannot be guaranteed

[0003] In order to solve the above-mentioned problems, CN208767573 U discloses a kind of pincer structure communication line, but this structure is only applicable to the situation that has unique communication agreement and port, and CN207366034U discloses a kind of non-contact meter reading by infrared method, but this method In practical applications, it is easy to cause abnormal data transmission and reception due to dust pollution on the infrared window
