Embodiment 1

[0048] Based on the above ideas, this embodiment proposes a daisy chain two-wire temperature measurement system, such as figure 1 As shown, it includes a main module for obtaining temperature signals and multiple temperature detection slave modules for detecting temperature signals. The main module and multiple temperature detection slave modules are connected in series through power lines to form a daisy chain temperature monitoring network. The temperature detection slave module modulates the detected temperature signal into a corresponding current signal and transmits it through the power line, and the master module decodes the current signal on the power line to obtain corresponding temperature data.

[0049] In this embodiment, a plurality of temperature detection slave modules all include a temperature transmission upper interface and a temperature transmission lower interface connected to each other, and the temperature transmission upper interface of the next-level temp...

Embodiment 2

[0077] The difference between the second embodiment and the first embodiment is that the internal structure of the main module is different from the main module in the first embodiment.

[0078] In the second embodiment, if Figure 7 As shown, the main lower bus switch is connected between the lower temperature transmission interface and the main controller. In addition, a sampling resistor R is connected in series between the lower temperature transmission interface and the main lower bus switch. The signal demodulation module and the sampling resistor R Parallel and connect the main controller.

[0079] In the second embodiment, the technical solutions and technical effects in the first embodiment can still be achieved by adjusting the internal structure of the main module, so details are not repeated here.

Abstract

The invention relates to the field of communication, in particular to a daisy chain two-wire system temperature measurement system and method. The system comprises a main module and a plurality of temperature detection slave modules, and the main module and the plurality of temperature detection slave modules are sequentially connected in series through power lines to form a daisy chain type temperature monitoring network. Each temperature detection slave module comprises a temperature transmission upper interface and a temperature transmission lower interface which are connected with each other, and the temperature transmission upper interface of the next-stage temperature detection slave module is connected with the temperature transmission lower interface of the previous-stage temperature detection slave module through a power line so as to directly transmit a temperature signal to the main module; the temperature detection slave modules modulate detected temperature signals into corresponding current signals and transmit the current signals through the power lines, and the main module decodes the current signals on the power lines to obtain corresponding temperature data. Through the daisy chain type temperature monitoring network, the system is easy to expand; the power supply and communication collinear technology is utilized, and power supply and data transmission are achieved only through a power line.
