Starting a business is not easy, but fortunately, Dandelion R300 series 4G wireless routers help field weather monitoring

Editor’s note: As a domestic self-developed SD-WAN intelligent networking service provider, Dandelion, a subsidiary of Beirui, is committed to providing users with simple and easy-to-use cost-effective intelligent networking services, in addition to pursuing the corporate philosophy of “doing no evil if you are warm” . Among them, the Dandelion R300 series industrial-grade 4G wireless router is a cost-effective professional networking equipment for the industrial environment, which can help small and medium-sized enterprises to realize the remote data collection and outdoor video monitoring of IoT industrial control equipment at low cost. Transmission, unattended intelligent terminal wireless data transmission, etc. The data return and remote management and maintenance scenarios of field weather monitoring in this paper are just the real case shared by a personal entrepreneurial user.

Difficulties in field weather monitoring

I used to work as a project manager in a technical service-oriented enterprise integrating meteorological application software, hardware and system implementation, mainly doing meteorological equipment. To monitor the data of the automatic meteorological observation system, it is necessary to be able to detect the errors, deletions and changes of the data in time to ensure the accuracy of the data. Reliable data monitoring is beneficial to reduce observation errors, prevent the occurrence of unsafe events, and improve the quality of observation work.

There are many problems encountered in the actual monitoring process:

(1) The monitoring points are scattered in the wild, the environment is generally harsh, and the distance between each point is relatively long, which makes it inconvenient to collect and return data manually;

(2) Meteorological monitoring has high requirements on the immediacy of alarms, and requires a complete set of remote management and maintenance solutions;

(3) The field environment is complex, and even without considering the cost, it is unrealistic to use optical fibers.

Why choose Dandelion

In order to overcome the difficulty of field weather monitoring, I searched for a suitable solution through the network, and learned about Shanghai Bairui’s Dandelion SD-WAN intelligent networking. At that time, Dandelion hadn’t started to make industrial routers, and the first one I bought was Dandelion X5.

The X5 is an enterprise-level desktop router. Because the hardware supports 7-day returns and exchanges without any reason, I bought a few to try them out. Although the 3G/4G USB adapter is supported for networking, the effect is also good, but it is not suitable for long-term use in the wild.

Later, there was an R300 series dedicated to 4G industrial routers, and I quickly bought two. The R series are very compact. The dimensions of the R300A and R300S are only 96 × 94 × 28 mm, which is more than enough to put in the box at the inspection point. The overall design is simple and elegant, and the sheet metal shell feels very good.

Moreover, although the sparrow is small and complete, the power supply terminal is a 2-pin 5.08mm industrial terminal, DC wide voltage 5-36V, supports grounding, and the protection level reaches IP30, which can run stably in the field for a long time.

R300A supports 4G full Netcom IoT card with 2 100M ports; while R300S supports full Netcom with 5 100M ports. After testing, the transmission effect is good, and the price is reasonable. A R300S is less than 500 yuan. It can be said that strength and beauty coexist.

Because R300S supports 4-mode 9-band full Netcom, I finally decided to purchase R300S in bulk.

Dandelion networking is very simple. Put a Dandelion router at the main station and each monitoring point. On the management page, put the router members that need to communicate with each other in the same networking network to avoid IP network segment conflicts. I think it supports the combination of software and hardware, and I also bought an access member, which is very convenient to log in with a computer or mobile phone at any time for cloud monitoring and cloud maintenance.

With Dandelion, the collection and transmission efficiency of data, images and videos in the field weather monitoring station has been greatly improved, and the situation of each monitoring point is under control. R300 can fully meet our current needs, I decided to replace all X5 with R300S later.

Starting a business is not easy, Dandelion helps me

I am very grateful to the leaders for their kindness, but the main business of the company turned to software. After careful consideration, I decided to leave the original company and start making equipment and IoT cards by myself.

In China, the success rate of entrepreneurship is very low. Policy, timing, technology, contacts, investment, industry experience. . . . . . It will have a huge impact on the success of a business. Fortunately, I encountered Dandelion before starting a business. At least the technical problems of remote meteorological monitoring are basically not a problem. It has saved me a lot of energy and greatly improved my confidence on the way to start a business!
