Outdoor temperature control machine box

Abstract

The invention relates to temperature control machine boxes, in particular to an outdoor temperature control machine box. The outdoor temperature control machine box comprises in-box monitoring equipment, a machine box electric brake, a demisting and defrosting system and an integrated manager. The machine box electric brake supplies power to the integrated manager, the integrated manager is connected with the in-box monitoring equipment, the demisting and defrosting system and a monitoring and management side outside the box, cooling fins, a temperature induction probe and a temperature controller are arranged in a box body of the temperature control machine box, a Peltier temperature control sheet is arranged between the cooling fins and the inner wall of the box body, and the temperature induction probe is used for detecting temperature in the temperature control machine box. When the temperature is larger than set temperature, the temperature controller increases the current of the Peltier temperature control sheet so that the Peltier temperature control sheet can achieve refrigeration, and when the detected temperature is smaller than the set temperature, the temperature controller decreases the current of the Peltier temperature control sheet to reduce heat radiation of the Peltier temperature control sheet. The temperature of the temperature control machine box can be basically constant, and therefore it is ensured that the monitoring equipment in the machine box works normally.

Description

technical field [0001] The invention relates to a temperature control cabinet, in particular to an outdoor temperature control cabinet. Background technique [0002] The temperature-controlled chassis is mainly installed on the brackets or poles along urban intersections or traffic arteries. One or several monitoring devices can be placed in the chassis according to the purpose, such as: cameras, embedded recognition algorithm hosts, network video servers, hard disk recorders, etc. Monitoring equipment, these devices can complete the all-weather monitoring and recording of road checkpoint capture, red light capture, speeding vehicle recording, license plate recognition, and drivers who are not wearing seat belts. In the harsh outdoor environment, the temperature-controlled chassis can effectively protect these devices, realize lightning protection, dust-proof, rain-proof, anti-fog, frost-proof, etc., and ensure that the monitoring equipment in the temperature-controlled chas...

Problems solved by technology

[0003] The traditional temperature control chassis includes the chassis switch, temperature control system, lightning protection system, and the monitoring equipment in the box connected to the monitoring and management terminal through Ethernet. Connect the monitoring and management terminal through Ethernet. Through this chassis structure design, it is guaranteed to be rainproof and dustproof, and the temperature control switch can control the heating resistor or fan to maintain the temperature of the chassis. However, the temperature control chassis is not recommended for outdoor use, even if For outdoor use, there are also many restrictions

Since some sophisticated and expensive monitoring equipment (such as high-definition cameras, hard disk video recorders, embedded recognition algorithm hosts, etc.) have strict requirements on temperature and humidity, if they work in harsh environments, their service life will be reduced, and even they will not be able to start or be damaged. While these devices are expensive, extreme care should be taken when using them

Due to their high degree of intelligence, they play an indispensable role in security fields such as intelligent transportation, so they have to be used in outdoor environments, but the protection capabilities of traditional chassis can no longer meet the requirements, and it is necessary to carry out temperature control chassis Improve it to meet the relevant requirements for use
