Description
Technical field
The present invention relates to the measuring techniques of wireless signal, more particularly, to a kind of wireless signal detection device, including this
The system and method for the measurement wireless communication signals quality of device.
Background technique
In industrial internet of things field, internet of things equipment is much network internet by wireless communication, carries out remote access control
System.The place of internet of things equipment deployment often extremely disperses, the wireless communication signals intensity of each device context, signal quality etc.
It is all not quite similar, this and radio communication operator are closely related in local network deployment.And China Mobile, China Telecom and
The big radio communication operator of China Unicom three, the range and dynamics that network is disposed in various regions are different, cause samely
Side, using the network of different operators, signal quality is also not quite similar.Such as: equipment A is deployed in district in Beijing, uses China
Mobile 4G network, signal quality are 4G network that is excellent, and using China Telecom, and signal quality is very poor；Equipment B is deployed in extensively
The area Xi Mou, using the 4G network of China Mobile, signal quality is very poor or does not have 4G signal, but uses the 4G net of China Telecom
Network, signal are fine.It can thus be equipped with the 4G SIM card of China Mobile to equipment A, the 4G of China Telecom is equipped with to equipment B
SIM card.This just there is an urgent need to have the wireless signal strength and communication quality of each operator of a kind of device or scheme detection scene, from
And reference is provided for the SIM card which operator is equipment be equipped with.
At present in China, needing to detect includes but is not limited to that China Mobile, China Unicom and China Telecom three transport greatly
Seek the network signal quality of quotient, including 4G network, 3G network, 2G network and NB-IoT network.
In addition, internet of things equipment network internet by wireless communication, is finally to solve data communication problem.Therefore,
Whether the data link between equipment and the communication server is unimpeded, and data communication delay, packet loss etc. and user are urgently concerned about
The problem of.
In wireless communication field, communication equipment such as mobile phone etc. is communicated by wireless networks such as 2G/3G/4G.Wireless network
Network operator is responsible for construction and maintenance wireless network, in various regions deployable communication such as China Mobile, China Unicom and China Telecom
Base station.The wireless network of communication equipment access carrier is by realizing with neighbouring communication base station receiving and transmitting signal.Equipment is received
The signal issued to base station, it is related with the transmission power of base station and the distance between base station and equipment.The transmission power of base station
Bigger, base station is closer at a distance from equipment, and equipment is easier to receive signal, and the signal power received is bigger, representation signal
It is stronger.The proprietary term of setting a batch is used to indicate the power of signal in the industry, wherein significant term has: (reference signal connects RSRP
Receive power), RSSNR (reference signal signal-to-noise ratio) etc..RSRP is the value of an expression power absolute value as unit of dBm, can also
By a ratio being considered on the basis of 1mW power, calculation formula are as follows: 10log (performance number/1mW).Such as: 0.01mW's
Power, corresponding RSRP are 10log (0.01/1)=- 20dBm.RSRP is a negative, indicates that signal strength is higher closer to 0,
Signal is better.RSSNR indicates the relative size relationship of signal and noise two amounts, calculation formula are as follows: 10log as unit of dB
(signal power/noise power), generally between -20~+30dB, value is bigger, indicates that signal quality is better.
Whether communicated in IP communication network, between communication node it is unimpeded, generally use ICMP agreement, pass through send ICMP
PING request packet and reception ICMP PING response bag are tested.For example, it is desired to judge that the IP between equipment and server is communicated
Quality, equipment continuously transmit 10~50 IMCP PING request packets to server, and then statistics receives ICMP PING response bag
Time and do not receive the ratio of response, and then the communication delay and packet loss of link between equipment and server can be calculated
Rate.Time delay is smaller, and packet loss is lower, illustrates that communication quality is higher.
Currently, showing connection network type on mobile phone interface, and with the power of lattice number id signal.And Android hand
The function of machine and iOS mobile phone query signal strength.Such as Android phone, point setting -> about mobile phone -> status information, it can
To find currently used network type and real-time signal strength value, shown with dBm and asu (lone signal unit).Internetworking
Aspect, the SmartTest network testing software that China Mobile releases can be tested, while having computerized version and mobile phone version, net can be carried out
The test of speed, including speed of download and uploading speed, while communication quality is tested by PING request packet and response bag.
About signal strength is tested, the signal strength query function built in mobile phone can be with real-time display signal strength.But
It is only able to display the signal strength of currently used network, can not test simultaneously and shows China Mobile, China Unicom and China Telecom
The signal strength of the different network formats of three operators can not compare to make network selection.And it can only on mobile phone
Query display RSRP cannot inquire RSSNR.Although RSRP is the important indicator of signal quality, it is frequently necessary to consider simultaneously
RSSNR, so as to comprehensive descision signal quality.The SmartTest network speed of China Mobile tests APP, can pass through ping testing net
Network communication quality, but since mobile phone supports the limitation of network and SIM card slot number, three operators can not be tested simultaneously
The communication quality of different network formats.
