Power control method and device based on text language

Abstract

The invention discloses a text language-based power supply control method and a text language-based power supply control device. The method comprises the following steps of: acquiring a triggering signal generated by a customized trigger strategy or user input, and identifying at least one preset communication event identifier according to the triggering signal or the user input; and performing at least one processing corresponding to the communication event on a corresponding monitored power supply according to the triggering signal or the input and at least one communication event identifier. By the adoption of the method and the device, the transmission distance can be increased by communicating by adopting RS485; and during an implementation process, the connection of a plurality of monitored power supplies can be realized by only using a small amount of RS485 interfaces, so that less wires are connected; and therefore, the wiring is attractive, and the use experience of users is improved.

Description

technical field [0001] The present invention relates to the technical field of power management, in particular to a text language-based power control method, device and system. Background technique [0002] At present, in the technical fields of factory automation, communication, and new energy, in order to be able to monitor and control power supply information in real time, it is necessary to perform real-time online or manual settings for the power information, voltage information, and current information of the power supply. , It is also necessary to collect real-time information such as the real-time status of the power supply and related alarm feedback. [0003] Based on this, the prior art generally includes the following three processing methods: [0004] The first type is that the monitored target power supply is not connected to the control line, and its related setting and control are carried out manually, and the collection of feedback information mainly relies ...

Problems solved by technology

[0008] On the one hand, the wiring is complicated, so in the case of many wirings, a special design is required for the wiring, which increases the design cost on the one hand;

[0009] Due to the relatively poor anti-interference ability of the analog quantity, the signal attenuates significantly with the increase of the transmission distance. As the number of power supplies increases, the number of analog input and output modules and I / O modules needs to be increased, resulting in an increase in cost;

[0010] The alarm information of the three power supplies cannot be displayed intuitively on the monitoring center, and it is necessary to confirm the fault information code on site, which is time-consuming and labor-intensive.

[0011] The third is to install a bus card on the target power supply to be monitored, such as installing PROFIBUS or DeviceNet. However, this type of bus card is relatively expensive and will easily lead to an increase in the overall cost. For example, the cost of a PROFIBUS or DeviceNet card is usually more than 2,000 yuan; , since the power supply requires a specific bus card, the power supply is also not scalable

[0012] In addition, this method of installing bus cards has limitations to a certain extent, because not all power supplies can be installed with bus cards, and this method cannot be used for those power supplies that do not support the installation of bus cards. Handling of Power Information
