Distribution box intelligent edge terminal based on industrial Internet of things

Abstract

The invention discloses a distribution box intelligent edge terminal based on industrial Internet of things. The distribution box intelligent edge terminal comprises a CPU module, and an analog quantity input module, a digital signal input module, a relay output module, a power supply module and a communication module which are connected to the CPU module. The analog quantity input module is connected with a current sampler and a temperature sensor, the current sampler collects the current of a system power supply of a distribution box, and the temperature sensor detects the temperature of anoutput power supply cable of the distribution box and the ambient temperature of the distribution box; the relay output module is connected to a control circuit breaker and a control lock of the distribution box; and the CPU module exchanges data with a remote monitoring system through the communication module. The load of the distribution box is acquired through the current sampler, the ambient temperatures of the load cable and the distribution box are acquired through the temperature sensor, and a data basis is provided for power utilization safety analysis. Reliable long-distance wirelesscommunication is realized through cooperation of a Lora module and a 4G / 5G wireless module.

Description

technical field [0001] The present invention relates to an intelligent terminal device, in particular to an intelligent edge terminal of a power distribution box based on the Industrial Internet of Things. Background technique [0002] The construction site is inseparable from the use of electricity, engineering equipment, construction machinery, on-site lighting, electrical installation, etc., all need the support of electric energy. With the strengthening of scientific and technological content and intelligence of construction projects, the continuous improvement of construction mechanization and automation, the use of electricity is more extensive. However, while electric energy brings convenience to human beings, it also has strong destructive power. Due to the characteristics of many types of electrical equipment, large capacitance, unstable working environment, open-air operation, and temporary use, construction sites are prone to electric shock casualties. At the sa...

Problems solved by technology

There are still the following disadvantages in the use of intelligent distribution boxes: 1. It is impossible to collect the power consumption of the distribution box, and the distribution box has the risk of overloading; 2. There is no monitoring of the load power supply cable of the distribution box. When the load is too large, The temperature of the cable is too high, which poses a safety hazard; 3. The wireless communication distance of the smart distribution box is short, which cannot meet the needs of long-distance data transmission; 4. It is necessary to transform the original distribution box into a smart distribution box, which is cumbersome and heavy workload ,high cost
