Description

Multichannel receiver with health degree management function

Technical field

The utility model is related to receiver fields, and in particular to a kind of multichannel reception with health degree management function Machine.

Background technology

The major function of receiver is to select the frequency content of oneself needs, suppression from aerial existing numerous electromagnetic waves Unwanted signal or noise and interference signal are made or filtered out, then obtains original useful information by amplification, demodulation.It receives Machine constitutes structure there are two types of basic, and one is superhet (superhetrodyne) structure, another kind is direct transformational structure.Institute Call superhet, exactly by the radiofrequency signal received be mixed with the local oscillation signal of a certain frequency or down coversion after A lower modulated intermediate frequency signal of frequency is exported, the frequency of the intermediate-freuqncy signal is exactly the frequency of local oscillation signal and the signal being received Fixed frequency difference between rate.The demodulation of final signal is will to be completed by demodulator on intermediate frequency after intermediate-freuqncy signal filtering, amplification. In direct conversion receivers, basic principle is same as heterodyne reciver, the difference is that participating in the local frequency of mixing is not Any given, and it is equal to carrier frequency, such IF frequency is just 0, so or else there is image frequency and image interference, This scheme is commonly referred to as zero intermediate frequency scheme.The radio frequency part of the program eliminates image frequency filter, and intermediate-frequency filter becomes Low-pass filter, simplifies the composition of system, reduces the difficulty of design and realization, saved cost.But it directly converts Receiver have the shortcomings that it is apparent, it is such as identical with carrier frequency due to the frequency of local oscillator, therefore be easy to cause the leakage of local oscillator；In the presence of DC deviation causes to seriously affect to subsequent circuit；It is only used for the demodulation of amplitude-modulated signal, frequency modulation and phase modulation letter cannot be demodulated Number；It is high to the stability requirement of local oscillator, so most only use in low-frequency range.According to channel classification include multichannel receiver, Sequential channel receiver, multichannel are mostly used channel receiver.

Disadvantage of the prior art is that：The job information of receiver only has two states, i.e., normally and failure, can only therefore It is replaced after barrier, can not accomplish failure predication.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of more with health degree management function Channel receiver can predict the fault message of multichannel receiver, be conducive to reliability and the repair of lifting means Property.

The purpose of this utility model is achieved through the following technical solutions：

A kind of multichannel receiver with health degree management function, the multichannel receiver include health degree management module With multiple receivers, the active component of each receiver is each equipped with the sensor of detection voltage, electric current, temperature, the biography The signal that sensor detects is converted into digital signal by ADC module, and the digital signal is converted into I2C by I2C converters Then data are uploaded to health degree management module by formatted data by I2C buses, the health degree management module, which is provided with, to be connect The threshold value of voltage, electric current, temperature under receipts machine normal operating conditions, once the voltage detected, electric current, temperature signal are more than threshold value Health degree management module prompts warning message.

As being further improved for this programme, the voltage detected, electric current, temperature are uniformly converted into electricity by the sensor Press signal.

Preferably, the health degree management module includes processor, display screen, precaution device, and the display screen is for showing The data information of reception, the processor are connect with precaution device, and when the data information of reception is more than threshold value, processor control is pre- Alert device sends out early warning.

The utility model has the beneficial effects that：This programme is sensed by being designed around the core active component to receiver Device quantifies temperature, voltage, electric current, realizes that the health degree information of multichannel receiver reports with I2C buses, is good for simultaneously Health management module is built-in with the threshold value under the normal operating conditions of each active component of receiver（The threshold of voltage, electric current, temperature Value）Once detecting that a certain working state signal is more than threshold value or is less than threshold value, then it is considered as non-normal working, to convenient pair The maintenance of receiver avoids the generation of failure in advance.

Description of the drawings

Fig. 1 is the system block diagram of the utility model.

Specific implementation mode

The technical solution of the utility model, but the scope of protection of the utility model are described in further detail below in conjunction with the accompanying drawings It is not limited to as described below.

As shown in Figure 1,

Multichannel receiver with health degree management function, the multichannel receiver include health degree management module and nine A receiver（Number is receiver 1, receiver 2, receiver 3 ... receiver 9 respectively）, the active component of each receiver It is each equipped with the sensor of detection voltage, electric current, temperature, voltage detecting sensor is respectively configured to each receiver, electric current is examined Sensor and temperature detection sensor are surveyed, the voltage detected, electric current, temperature are uniformly converted into voltage by last sensor to be believed Number, voltage signal is converted into digital signal by ADC module, and digital signal is converted into I2C formatted datas by I2C converters, Then data are uploaded to by health degree management module by I2C buses, it is normal that the health degree management module is provided with receiver The threshold value of voltage, electric current, temperature under working condition, once the voltage detected, electric current, temperature signal are more than threshold value health degree pipe It manages module and prompts warning message.
