Refrigerator\'s controller and alert

Warehouse temperature control is a means to maintain the conditions of warehouses and cold storages with the best product quality and reduce losses related to material spoilage. Storage warehouses for food-dairy-sanitary-medical-paper-clothing-rubber and... all should be within a certain range of temperature and humidity so that their quality does not change during the storage period. In order to store these materials in roofed warehouses, cooling and heating systems are generally used to keep the temperature within the permitted range of the product, but sometimes the failure of the heating and cooling systems or their failure will cause the temperature or humidity to go out of the standard range. If the warehouse situation remains the same, in the case of food products, a delay of more than 1 day may cause them to spoil, and in the case of warehouses that store sanitary goods, the sensitivity of the matter is the same, but the existence of such problems should not cause spoilage. What is the solution if the goods are delivered prematurely or their quality is reduced? The solution is to use warning systems that can measure the temperature and humidity of the warehouse at any moment and give a warning to the employer and the system maintainer if the acceptable range is exceeded. Warnings in I-systems can be in the following forms 1-Warning in the form of a siren 2-Warning in the form of an optical flasher 3- SMS alert 4-Warning in the form of a voice message Each of the above methods alone and together can inform the employer of the existence of a warning so that a solution can be thought of Work resume Photos of projects

Smart server room and intelligence server room is a topic that these days is a lot of noise these days, the smart server room refers to places that, using electronic welfare systems, provide more safety to its managers and ultimately create a good sense of server room maintenance \r\n\r\n\r\nOf course, two groups of individuals are intelligent to control the server room environment, which is the first category of managers who have recently encountered a crisis in the server room where the lack of intelligent server room system has caused a crisis and damages in hardware and data, and the second category are managers who have received non -Certificate or Certificate of Certificates.\r\n\r\n\r\nEquipping the server room intelligent control can happen with any brand, but the service by all brands is not the same and reliable. It is necessary for the IT manager to have an obsessive -compulsive intelligent system in order not to regret the wrong choice in the future.\r\nSee the project photos here\r\nhttps://pishransa.com/pictures/\r\n\r\nIn the SRC2.2 system, a powerful industrial controller is used as a systemic brain, which is the world's most prestigious industrial processor. This processor does not even use 10 % of its capabilities in the most sophisticated server room in the server room.\r\nIn several glances, the intelligent server room can raise the opinion of users to encourage it to be implemented.\r\n\r\nSee our resume here\r\nhttps://pishransa.com/projects/\r\n\r\n1) With the Smart Server Room we can say the server room will move toward integration\r\n\r\nFor example, control of all areas in the server room, including racks and UPSs and electrical and physical parameters by the central panel and the organization's software console in each of the rooms of the organization will be.\r\n\r\n\r\n2) The smart server room has the ability to create more prosperity for the user\r\n\r\nControlling every single parameter that can be traumatic in some situations and the room is in crisis will eliminate the sense of confusion.\r\n\r\n\r\n\r\n3) The smart server room provides more safety for users in equal conditions\r\n\r\nThe existence of gas leak control systems, water control and warning, smoke and fire alert with temperature and humidity gives the manager a good sense of control and safety, even smart systems at the time of the user's departure from the server room, and the power of the electrical equipment and the potential defects, as well.\r\n\r\n\r\n4) The Smart Server Room will have security against theft and unauthorized entry\r\n\r\nIntelligent systems in addition to temperature monitoring use Access to Exit and Exit This System.
