Electronic stop board system based on a protection strategy scheme

Abstract

The invention discloses an electronic stop board system based on a protection strategy scheme, which modularly manages all integrated electric appliances in an electronic stop board and comprises a management platform, an industrial personal computer, an integrated controller, a temperature and humidity sensor, a switch and electronic equipment of the electronic stop board, and the management platform is connected with the industrial personal computer through a communication module; and the integrated controller is connected with the industrial personal computer, and the integrated controller is connected with the electronic device and the switch. The centralized controller is connected with the temperature and humidity sensor, and the centralized controller internally comprises a 485 module, a current monitoring module, a voltage monitoring module, a 24V input and output module, a 12V input and output module and a 5V input and output module. According to the invention, independent strategy protection can be carried out on electric appliances in the electronic stop board; and the equipment damage probability can be reduced, and the operation and maintenance cost can be reduced through software control.

Description

technical field [0001] The invention relates to the field of electronic stop sign security, in particular to an electronic stop sign system based on a protection strategy scheme. Background technique [0002] Strategic protection is a scheme based on equipment safety protection, which is suitable for multiple electrical integrated equipment. Through the strategic protection of each module electrical equipment, the mutual interference between each module is reduced, and a single module is overvoltage, overcurrent, temperature, etc. If it is too high, it can be dealt with separately, and it can be dealt with according to the specific situation, which reduces the coupling of each module, greatly improves the service life of the equipment, and reduces the operation and maintenance cost. [0003] The existing technical solution is to add an air switch on the electronic station sign, and when an electrical appliance in the equipment has overcurrent or overvoltage, the entire equip...

AI Technical Summary

Problems solved by technology

[0003] The existing technical solution is to add a circuit breaker on the electronic station sign. When an electrical appliance in the equipment has overcurrent or overvoltage, the entire equipment will be powered off.

In addition, the existing electronic station signs are integrated with various electronic devices such as fans, power supplies, display screens, LEDs, light strips, nvr, routers, etc. These electrical components cannot be over-current, over-voltage, or flooded If the power is automatically cut off from time to time, if it is all manual inspection, the operating cost will also increase greatly, and it cannot be dealt with in a timely and effective manner, which will easily cause damage to the equipment, and once an electrical appliance in the equipment is over-current or over-voltage, it will cause the entire electronic station to be damaged. Brand equipment cannot be used, greatly increasing the probability of failure
