Abstract
The utility model relates to a cascading loop type power supply/communication on-line monitoring apparatus, comprising a power supply/communication terminal, various monitoring units and cascading lines, wherein the power supply/communication terminal is provided with two connection ports used for forming a cascading loop, each monitoring unit is provided with two cascading ports used for serial connection, all the monitoring units are orderly and correspondingly cascaded through respective cascading ports and the cascading lines, and the two cascading units respectively located at the front end and the tail end are correspondingly connected with the two connection ports of the power supply/communication terminal respectively through respective cascading ports and the cascading lines such that the power supply/communication terminal and various monitoring units form a closed loop. The cascading loop type power supply/communication on-line monitoring apparatus not only can resolve the problem that the monitoring units of the prior single line cascading type monitoring apparatus can not normally operate under the influence of overlarge line voltage drop in the process of application, but also has the advantage that when one monitoring unit breaks down, the other monitoring units in the loop can still normally operate.
Description
Technical field
The utility model relate to the power supply of a kind of cascade loop type the communication on-Line Monitor Device.
Background technology
Present power supply the communication on-Line Monitor Device mostly be the single-wire cascade formula, there is such defective in actual applications in the monitoring device of this version: along with the lengthening of connection line, increasing of load, the voltage drop value of cable can increase gradually, causes successor devices to work; Simultaneously, after certain one-level monitoring equipment breaks down, the directly normal operation of the follow-up monitoring equipment of impact.
The utility model content
The technical problems to be solved in the utility model is: for solve the power supply of present single-wire cascade formula communication on-Line Monitor Device line drop value when connection line lengthens load and increases can increase gradually and cause successor devices to work, and the problem that after certain one-level breaks down, can directly affect the normal operation of follow-up monitoring equipment, and provide the power supply of a kind of cascade loop type the communication on-Line Monitor Device, with replace the power supply of single-wire cascade formula communication on-Line Monitor Device and drop into application.
The technical scheme that its technical matters that solves the utility model adopts is: the power supply of a kind of cascade loop type the communication on-Line Monitor Device, include the power supply communicating terminal, each monitoring means and level on line, the power supply communicating terminal have two connectivity ports that are used to form cascaded loop, monitoring means has two cascade ports for serial connection, two cascade port and the level on line successively corresponding cascade of each monitoring means by separately, thus cascade port and the level on line of two monitoring means that are in the first and last end position by separately is unified into closed circuit with power communicating terminal and each monitoring means of the corresponding connection in two connectivity ports of power supply communicating terminal respectively.
Say that further described level on line is the concentric cable connecting line that two ends are connected to aviation plug.
The beneficial effects of the utility model are: the power supply of this cascade loop type the application of communication on-Line Monitor Device efficiently solve existing single-wire cascade formula power supply the problem that affects the normal operation of monitoring means because line drop is excessive that when using, exists of communication on-Line Monitor Device, this cascade loop type power supply communication on-Line Monitor Device also has after certain one-level monitoring means breaks down the advantage that other monitoring means can move as usual in the loop simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. the 3. grades of on lines of communicating terminal 2. monitoring means of powering
Embodiment
The power supply of a kind of cascade loop type the communication on-Line Monitor Device, as shown in Figure 1, its include the power supply communicating terminal 1, each monitoring means 2 and level on line 3, the power supply communicating terminal 1 have two connectivity ports that are used to form cascaded loop, monitoring means 2 has two cascade ports for serial connection, two cascade port and the level on line 3 successively corresponding cascade of each monitoring means 2 by separately, thus cascade port and the level on line 3 of two monitoring means 2 that are in the first and last end position by separately is unified into closed circuit with power communicating terminal 1 and each monitoring means 2 of corresponding connections in two connectivity ports of power supply communicating terminal 1 respectively.
Level on line 3 is connected to the concentric cable connecting line of aviation plug for two ends.
Claims (2)
1. cascade loop type power supply communication on-Line Monitor Device, include the power supply communicating terminal (1), each monitoring means (2) and level on line (3), it is characterized in that: the power supply communicating terminal (1) have two connectivity ports that are used to form cascaded loop, monitoring means (2) has two cascade ports for serial connection, two cascade port and level on line (3) the successively corresponding cascade of each monitoring means (2) by separately, two monitoring means (2) that are in the first and last end position by separately the cascade port and level on line (3) respectively with power supply communicating terminal (1) thus power communicating terminals (1) and each monitoring means (2) of the corresponding connection in two connectivity ports be unified into closed circuit.
2. cascade loop type according to claim 1 power supply communication on-Line Monitor Device, it is characterized in that: described level on line (3) is connected to the concentric cable connecting line of aviation plug for two ends.
