The Cymbidium hybrida, also known as Hulanlan, is a perennial herb of the evergreen, and is now the more popular flower of the year. However, many supporters claimed that the long-cherished orchid was too late to die and became a "one-time flower." The main points of its post-harvest care are described below for reference. 1. Go to flower buds. The Cymbidium grandiflora bought before the Spring Festival can generally maintain its flowering period from 25 days to 40 days. After flowering, it is necessary to cut the calyx in time to avoid excessive consumption of nutrients and affect the flowering in the coming year. 2. Spray water frequently. The cultivar "Yang Guolan" is suitable for Cymbidium grandiflorum because of its fleshy roots, low transpiration in winter and spring, and the water can easily cause rot, so it should be less watered. , Spray the plants often to maintain a certain humidity. 3. Light enough. Cymbidium Hibiscus scattered light, if the lack of light, easily lead to yellow leaves, it should be placed on the south window sill, to fully accept the light. 4. Keep warm. Cymbidium grandiflora hi warm environment, the winter room temperature should not be less than 8 °C, especially after the early spring to stop heating, if you do not take cold measures, it is easy to cause plants to be frozen and die. A simpler method of keeping warm is to cover the entire pot with a plastic film immediately after the heating is stopped and place it in a sunny room. If the temperature is still low, then apply a hotplate, open the warm air and other measures to increase the room temperature, and keep the room temperature above 10°C. 5. Change pots. After the giant flower orchids can not be eager to change basins, should wait until the Ching Ming season when the temperature is basically stable, the flower pot application of good permeability clay tile bucket, pelvic floor can be used to make the drainage layer shards, cultivation matrix can be used charcoal, Fine crushed stone, coarse sand, and annealed ceramsite are 1:1:3:1 proportioned and disinfected before spraying. What needs to be mentioned is that the cultivation substrate must be soaked with water before use. After the plants are put on the pot, they do not have to be irrigated, and only a small amount of water is needed to make the pot soils naturally dense.

The IOT card of the video surveillance camera needs to be stable enough to keep the flow normal during use without being stopped. After using the IOT network card with defective quality for a period of time, traffic theft or other abnormal conditions suddenly occur, resulting in card suspension, which makes the camera terminal unable to use normally, and may have a significant impact on the business. Generally speaking, video monitoring is event driven or abnormal images (some intelligent algorithms need to be supported) to generate high traffic usage. For example, monitor video playback or live broadcast via 4G/5G remote viewing. Generally, the daily standby traffic consumption is M, and the common definition of video viewing is about hundreds of M an hour.
Currently, for this application scenario, there are also several industry pain points for equipment manufacturers and solution providers:
SIM card adaptation, speed and security issues;
SIM card supply and price stability;
Be unfamiliar with the communication industry and solve the problem of failure;
One point access of multiple vendors.
