Huace Huayi E91 | RTK measuring instrument - Huace GPS 【 Wholesale/Rental/Maintenance/Calibration 】

Huayi Navigation is a brand new addition to the Zhonghui i series, Huayi X/T series, and Shuangwei M series of Huace Navigation. In mid year, the first RTK of the new brand, Huayi E91, was released, which is also the RTK that the editor will open the box to review today.

At the beginning of the release of E91, Huace Navigation was introduced as a five-year RTK. Is this really the case? Follow the editor to open the box and take a look.

The editor took a set of E91 mobile station and a set of 1+1. The suitcase on the left is the mobile station, and the suitcase on the right is the 1+1. The 1+1 set of E91 components are all placed in one box. The size of the 1+1 suitcase is approximately 58cm x 37cm, and the size of the mobile station suitcase is approximately 41cm x 33cm.

Next, the editor will open the boxes separately and take a look at what is inside the mobile station and the 1+1 box.

1+1



Firstly, upon opening the box, it appears quite messy. The radio antenna wiring is placed directly above the inner lining, which is difficult for OCD to accept. The storage area on the suitcase cover does not have lining material, which can easily cause damage to the host.



There are 12 storage areas in the inner substrate space, but there are no parts stored in the upper area where the notebook is placed. In addition, the "exposed" radio antenna wiring makes the interior space of the Huace E91 suitcase slightly unreasonable, and this small detail needs to be improved.

Generally speaking, 1+1 is a mobile station with one suitcase and one reference station with one suitcase. Huace has integrated the components of the two reference stations of the mobile station into one suitcase in the 1+1 kit of E91, which is commendable. For Huace, this is a small innovation.



It took a lot of effort to take out all the 1+1 components and place them on the table. There are a bit too many things and the table is a bit small, so the photos are a bit messy. Sorry~Take a look at what are there: notebook, notebook stylus, host X2, host pad X2, notebook holder pad X4, radio, E91 user manual, Type-C data cable Mini USB data cable, radio antenna wiring, battery power cable, 7-core wire, charging head, notebook holder, host

Power cord X2, 2 antennas, telescopic centering pole.

mobile station


The components of mobile stations need to be relatively simplified, with one less head, one external large radio, and some data/power cables. The mobile station suitcase comes with a product list, let's take a look at what's inside.



The editor has created a table image, which will be clearer when viewed.


Next, we will explain the individual components

When introducing E91 on the Huace official website, a prominent explanation was given on its anti drop and waterproof properties. In the situation where RTK motherboards and communication modules are similar in China, RTK resistance is also very important for users when using RTK.
The body material is made of AZ91D magnesium alloy, which can withstand a 2-meter free fall. The protection level of IP68 has reached a higher level of waterproof and dustproof for instruments, and there is no need to question this. It has been tested by professional institutions. E91 has also made some design in terms of drop resistance, with 6 buffer structures at the corners covered by covers (inside the red box), which can provide cushioning when the host falls.

Huace is quite dedicated to the design of the E91 host's anti drop capabilities. In the absence of significant differences in RTK host technology, Huace should also be praised for its attention to detail in finding new designs.



E91 has a built-in battery, so there is no battery compartment at the bottom of the host. The official website of Huace introduced that the built-in 10200mAh capacity battery of E91 can work continuously for 15 hours. The editor was a bit surprised and planned to test it. E91 will start working at full charge at 18:00 today and come back tomorrow at 9:00 to see the results.

There are 5 interfaces at the bottom of the host, namely SIM card slot/host charging port/data download interface/7-core interface/antenna interface.

Next, it's the front of the host



Two indicator lights, two function keys, two function keys and indicator lights. For a more detailed introduction of their functions, please refer to the E91 user manual attached at the end of the article.

E91 is paired with Huace's newer HCE320 notebook, a domestically produced notebook with a larger screen. Let's take a look together.

Firstly, let's take a look at the hardware. The 5.5-inch AMOLED screen, Android 7.1 operating system, 4G full network connection, and built-in 8000mAh capacity battery weigh 372g, which is much lighter than the previous generation HCE300.

Put a picture and compare it with HCE300



It is evident that Huace has made adjustments and upgrades to the screen size, body size, and button layout of the HCE320.

Next, let's take a look at HCE320

The HCE320 notebook body has two interfaces, one power Type-C port and one SIM card+storage card slot. This 2-in-1 card slot is the same as the iPhone SIM card slot and needs to be removed with a needle. Can be taken out in conjunction with the tip of a drawing pen.




The built-in measurement software in the notebook is Huace's Geodetic Platform. If you want a video tutorial, you can add WeChat:

radio station

E91 radio supports multiple radio protocols and can be used in conjunction with RTK from other brands in the market.


summary

The E91 is equipped with a large 10200mAh battery that can last for 15 hours, which is quite surprising. 2.5-hour fast charging, which can fully charge 80% of the battery in 3 hours, is quite helpful for long-term field work. E91 has put a lot of effort into the durability of the host, with excellent attention to details such as drop resistance, waterproofing, and dust prevention. While pursuing technological innovation, it also strives to improve the quality of the body. Additionally, the integration of 1+1 components into one suitcase is a surprising and satisfying aspect.

Later on, the editor would like to talk about the notebook. The HCE320 notebook is also eye-catching. Compared to the previous HCE300, the body has become thinner and lighter, and the screen has been replaced for better tactile operation. It is more comfortable to touch with hands compared to the previous generation. The combination of the drawing pen card and HCE320 is also full of small details and highlights. However, what is more important is that although the HCE320 notebook is good, my own phone is better. I believe that the free Geodetic software will win more customers, after all, measuring with a phone is much more convenient than a notebook.
