With the continuous development of the network and the continuous progress of various industries, some new concepts and development directions have actually emerged during the period. For example, from the current point of view, many enterprises in the development process in order to have good efficiency and speed, as well as the use of more functions, gradually began to use industrial routers. Of course, for this type of router, we also have a lot of problems, so today we will discuss to see, what is an industrial router? Which industries are they mainly used in?
What is an industrial router?
From the basic concept, an industrial router is a wireless data transmission function that provides users with wireless data transmission through a public wireless network. For example, we use mobile phone data to transfer things to another mobile phone or computer, in fact, the principle is very simple. Of course, the specific usage operation is different. In the process of use, the industrial router has the advantage of allowing multiple users to use the same integrated network system to access the network, which is also very convenient in the work. In fact, at present, industrial routers are gradually widely used in different industries, and the practicability is also very strong.
Industrial routers are mainly used in what industries?
The first is some of the contents summarized for the concept and basic principles of industrial routers, and for the use of industrial routers, it is also some of the issues that we are concerned about. From the current point of view, the first is widely used in intelligent transportation, such as in the application of high-definition electronic bayonet, road wireless video surveillance, vehicle monitoring or security monitoring, etc., which is also very important; Secondly, it is also widely used in the financial industry, such as the use of wireless atm self-service terminals, wireless pos machines or other applications; In addition, it is the application of the power industry, such as transformer remote monitoring management, circuit line video surveillance and substation video surveillance and so on. In short, the use of industrial routers is also more extensive.
How to choose an industrial router?
Although the industrial router is widely used now, the choice we made at the beginning is still more tangled, from the feedback of the market, Movingcomm router is actually very good. According to the needs of the industry environment, based on SD-WAN+ Internet of Things, intelligent networking can then be formed into a large local area network through the cloud platform router in many places. Therefore, the focus of security monitoring can also be concentrated to complete the work of remote video surveillance, but also to meet the needs of remote working, for some of the industries we mentioned earlier, the practicality of this program is also very good. Moreover, the technology of remote networking and intelligent networking is also very mature, and the security and stability are also good. In short, the advantages of Movingcomm router are still many.
Which problems with the input impedance of the differential amplifier are easily ignored
There’s always something tricky about circuits, isn’t there? It’s like they’re conspiring against us sometimes. But let’s dive deeper into what might be going wrong.
Take a monolithic differential amplifier, for instance. This little integrated circuit houses both an operational amplifier (op amp) and at least four precision resistors all in one neat package. Analog designers love these because they’re great at converting differential signals into single-ended ones while simultaneously rejecting common-mode signals. A classic example is the INA134, which is designed to serve as a line receiver for a differential audio interface.
But here’s the catch—most engineers think this simple component is straightforward to use. Spoiler alert: it’s not always that easy. One overlooked detail is that the two inputs of the differential amplifier have different effective input resistances. By “effective input resistance,†we mean the resistance created by the internal resistor values and the way the op amp operates.
Let’s break this down with the INA134. If you check out Figure 2, you’ll notice the labeled input voltage and current along with the voltage at the internal op amp input node.
For the in-phase input, calculating the effective input resistance is pretty straightforward. As seen in Figure 2, R3 and R4 are in series. Assuming no current flows into or out of the op amp input, the effective input resistance can be calculated using Equation 2:
\[ R_{in} = R_3 + R_4 \]
Now, the inverting input is where things get interesting. Remember the ideal op amp rule? Both inputs should always be at the same potential (Equation 3):
\[ V_p = V_n \]
In this case, R3 and R4 form a voltage divider at the non-inverting input. The voltage at the non-inverting input (Vp) can be calculated using Equation 4:
\[ V_p = V_{in} \times \frac{R_4}{R_3 + R_4} \]
This matters because the voltage at the non-inverting input influences the effective input resistance of the inverting input. The current through R1 (IIN(N)) is simply the voltage across R1 divided by its resistance (Equation 5):
\[ I_{IN(N)} = \frac{V_{in}}{R_1} \]
Substituting this into Equation 1 gives us a general formula for the inverting input resistance (Equation 6):
\[ R_{in} = \frac{V_{in}}{I_{IN(N)}} \]
The effective input resistance of the inverting input depends on the ratio of the voltages at the two inputs. Let’s consider an audio line receiver application where the input voltages are equal in magnitude but opposite in polarity (Equation 8):
\[ V_{in+} = -V_{in-} \]
At the non-inverting input, the effective input resistance is relatively simple, as shown in Equation 2:
\[ R_{in} = R_3 + R_4 \]
However, the inverse relationship between the two input voltages significantly affects the effective input resistance of the inverting input (Equation 9):
\[ R_{in} = \frac{R_3 \cdot R_4}{R_3 + R_4} \]
This means the effective input resistance of the inverting input is only one-third of that at the non-inverting input. When designing, remember that the inverting input has a lower impedance, so you’ll need to select an appropriate input coupling capacitor and filter circuit accordingly. Additionally, any amplifier driving the input of the differential amplifier must be capable of handling the lower impedance of the inverting input.
It’s funny how even the simplest circuits can trip us up in the lab. Don’t underestimate the basics—they’re often the source of the biggest headaches.
And remember, when troubleshooting, sometimes the solution lies in looking at the fundamentals.
