A control system and control method for photo files out of warehouse

Abstract

The invention provides a novel photo archive delivery control system. The novel photo archive delivery control system comprises a heat-insulating box, wherein box doors are arranged in the front and at the back of the heat-insulating box; and the heat-insulating box is provided with an inlet section, a temperature measuring section, a heat treatment section and an outlet section which are arranged from front to back. The novel photo archive delivery control system also comprises a photo placing grillwork, a mechanical transmission device, a temperature testing device, a semiconductor refrigeration and heating machine set and a controller, wherein the mechanical transmission device is arranged below the heat-insulating box, and the photo placing grillwork is arranged on a conveying belt of the mechanical transmission device. The invention also provides a novel photo archive delivery control method. The novel photo archive delivery control device and the novel photo archive delivery control method have the following advantages: 1, the reliability is high, and the working time and the working process are reduced; 2, the device is simple to operate; 3, the device is simple in construction and low in operating cost after installation and debugging; 4, the device can be controlled manually and also can be controlled automatically, and has high applicability.

Description

【Technical field】 [0001] The invention relates to a control system and a control method for photo file outbound. 【Background technique】 [0002] The preservation of photo archives has high requirements on temperature and humidity. Therefore, the country has issued a special specification GB / T 11821-2002 "Standards for the Management of Photo Archives" to clearly stipulate that the temperature of the black and white photo warehouse is 10-20°C, and the humidity is 55-60%; The temperature of the color photo warehouse is 13-17°C, and the humidity is 55-60%. The preservation value of photo archives lies in utilization. Only by actively developing the utilization value of photo archives and providing various valuable information resources for the society can we fully reflect the preciousness of photos and the historical value of archives themselves. Therefore, safe and reliable use of photo archives has become an important task for archives managers. [0003] Due to the lack of ...

Problems solved by technology

[0003] Due to the lack of professional knowledge of the management of temperature and humidity by archives managers, and the relative operability of the relevant norms is not strong: GB / T 11821-2002 "Standards for the Management of Photographic Archives" stipulates that the temperature and humidity of negative film and photo storage and the temperature and humidity of the room for use 1. If there is a large difference in humidity, a buffer room should be set up, and it should be transitioned in the buffer room for several hours before it is used.

This makes the process of photo files out of the warehouse to the buffer room lengthy and lengthy. At the same time, the temperature and humidity of the photo files change drastically, causing damage such as condensation on the photo files.

In this process, the change of temperature will obviously damage the photo files. At the same time, because the heat pump heating and cooling are used to achieve temperature control, although the problem can be solved, the cooling (heating) amount is very small, and the heat pump unit is not affected. Model selection design and product manufacturing put forward miniaturization requirements, which are generally difficult to achieve
