The embodiment of the invention provides an address assignment identification method and an address assignment identification circuit. The address assignment identification method is applicable to the address assignment identification circuit; the address assignment identification circuit comprises a monitoring module and at least one sensor, every sensor comprises a CPU (central processing unit) and a detecting module connected with the CPU; voltage drop on the detecting module of every sensor is equal to each other; the method comprises the following steps: CPU obtains voltage drop on the detecting module; CPU confirms number of the sensor in the address assignment identification circuit according to the voltage drop on the detecting module and the power source voltage provided by the monitoring module; CPU identifies address of the sensor of the CPU according to the voltage of the input end of the detecting module, the power source voltage provided by the monitoring module and number of the sensor in the address assignment identification circuit, and assigning address for the sensor where the CPU locates. According to the address assignment identification method provided by the embodiment of the invention, complexity of manual operation is reduced and speed of fault positioning is improved; and thereby the maintaining cost of the system is reduced.
Description
technical field [0001] The embodiment of the present invention relates to communication technology, and in particular to an address allocation identification method and an address allocation identification circuit. Background technique [0002] At present, in the system where multiple smart sensors are used in cascade, such as the application scenario of data center products, allocating and identifying sensor addresses is an important and necessary function. Such as figure 1 The application block diagram of multiple smart sensor systems is shown, which mainly includes a monitoring module and multiple sensors. Each sensor is connected in series and connected to the monitoring module. The monitoring module provides power for the sensor and provides a communication interface. The monitoring module and the sensor are connected under a communication bus. During normal operation, it is necessary to distinguish the address of each sensor. In the prior art, each sensor is provided...
