How to monitor the cold storage remotely?

1. Cold storage remote monitoring, you can change the main control board of the cold storage to a motherboard with GPS remote control function, and then the cold storage can be remotely controlled and monitored through the WeChat applet, and the control panel will analyze whether there is a failure risk according to the operating parameters.

2. It should be possible. Intelligent chips and temperature sensing components need to be installed, as well as intelligent software systems.

3. Real-time temperature printer with remote monitoring can be installed in the cab for temperature monitoring and positioning of refrigerated trucks. It depends on what items are stored and transported, such as: general seafoodThe requirements are qualified for storage and transportation below -18 degrees after quick freezing. If it is fresh vegetables and fruits, etc., it should be in the range of less than 4 degrees and more than 0 degrees. The requirements are different.

4. The installation method is the same, but the minimum starting temperature of the cold storage camera is relatively low, so a self-heating camera should be used. In addition, when the temperature rises, the front lens will have moisture, that is, fog up. Use a camera with automatic defrosting. If you think it is expensive, open the lid by yourself and put in the desiccant. OK.

5. If you want to monitor the temperature in real time in cold chain transportation, you need to install a monitoring system on the vehicle, which is mainly used to monitor and manage the cold chain transportation process, including temperature sensors, RFID, GPS and software management systems. These systems will generate feedback on temperature changes. , the effect of monitoring can be achieved.

6. For temperature and humidity, you can install several measuring points in each cold storage and then upload the network through GPRS. You can achieve centralized monitoring on your computer. Now the camera also has GPRS data uploaded, which can be connected to the temperature and humidity transmitter to realize the centralized monitoring of pictures and numbers.

Which level is not included in the industrial equipment remote monitoring system architecture? ()

Physical layer. According to the Baidu question bank test questions, which level is not included in the remote monitoring system architecture of industrial equipment? A. Physical layer;B. Perceptual layer; C. Transmission layer; D. Application layer. The answer is A, so it is the physical layer. The physical layer is a layer of OSI. Although it is at the bottom, it is the foundation of the overall open system.

The remote monitoring system architecture of industrial equipment does not include the physical layer, because the specific implementation of the physical layer depends on different network technologies and protocols, such as Ethernet, wireless network, VPN, etc., rather than part of the remote monitoring system architecture of industrial equipment.

Belongs to. The architecture of the industrial equipment remote monitoring system includes the perception layer, the transmission layer and the application layer. The application layer, also known as the application entity, consists of several specific application service elements and one or more public application service elements.

The three-layer structure type of the Internet of Things does not include the session layer, although it is in the Internet of Things systemThe structure has not yet formed a global unified specification, but at present, most literature divides the Internet of Things architecture into three layers, namely the perception layer, the network layer and the application layer.
