Multifunctional addressing device for multi-loop mining explosion-proof switch and addressing method thereof

Abstract

The invention discloses a multifunctional addressing device for a multi-loop mining explosion-proof switch and an addressing method thereof. The addressing device comprises a plurality of distributed modules, wherein each distributed module comprises following modules, including a characteristic value voltage compilation module used for obtaining a characteristic value voltage serving as the identification characteristic of each distributed module, a modulation module used for synthesizing the characteristic value voltage and a switching value signal, a volt-frequency conversion module used for converting a voltage signal into a frequency optical signal, and a receiving demodulation module used for converting the frequency optical signal into a frequency electric signal; the characteristic value voltage compilation module is electrically connected with the modulation module, the photovoltaic frequency conversion module is electrically connected with the modulation module, and the receiving demodulation module is optically connected with the photovoltaic frequency conversion module. The multifunctional addressing device for the multi-loop mining explosion-proof switch and the addressing method of the multifunctional addressing device are advantaged in that manual configuration is not needed, automatic addressing of the slave can be achieved after installation is completed, wireless transmission is adopted, and the wiring process is simplified.

Description

technical field [0001] The invention relates to the technical field of addressing methods, in particular to a multifunctional addressing device and an addressing method for a multi-circuit mine explosion-proof switch. Background technique [0002] Master-slave mode communication generally has one master and multiple slaves. The information sent by the master can be transmitted to multiple slaves or designated slaves, while the information sent by the slave can only be transmitted to the master, and the slaves cannot communicate directly. . In the multi-circuit mining explosion-proof switch using master-slave mode communication, each circuit unit as a slave is required to have a clear and non-repeated address. [0003] The existing addressing methods are divided into two methods: manual addressing and automatic addressing. Manual addressing has certain requirements for the operator. When the slave needs to be replaced, the address of the newly installed slave needs to be re...

Problems solved by technology

The other is to use the processing unit to identify external features such as different resistance values ​​or different voltages as the basis for address coding. The problem with this method is that there are many connections and it takes up more resources of the processing unit.
