For example, when upper-layer user's operator's console was received the numerical value 0 of communication module transmission, upper-layer user's operator's console was according to the program of inner setting, and point gives a green light, the normal connection status of expression antenna.When upper-layer user's operator's console was received the numerical value 3 of communication module transmission, upper-layer user's operator's console was according to the program of inner setting, and point sends out a warning, and the expression antenna is shorted to other voltage source states; Adopt simultaneously the buzzing type of alarm to cause that the user notes, with timely reparation.
With reference to accompanying drawing 3, the circuit framework schematic diagram of an embodiment of antenna condition monitoring equipment comprises antenna M40, antenna condition observation circuit module M41, communication module M42, upper-layer user's operator's console M43.Antenna condition observation circuit module M41 comprises power supply M411, resistance R 1, R2, R3 and R0, inductance L 1, capacitor C 1, and connection status of antenna M412.Communication module M42 comprises CPU module M421, analog to digital converter M422, aerial signal receiver M423 and ground protection port M424.Upper-layer user's operator's console M43 comprises control section M431 and state indicating device M432.
Antenna M40 is connected with aerial signal receiver M423 by antenna condition observation circuit module M41, aerial signal is sent to communication module M42, connection status between antenna M40 and aerial signal receiver M423 is divided into four kinds, be that antenna normally connects, antenna is shorted to ground, antenna does not connect, and antenna is shorted to other voltage sources.
Antenna condition observation circuit module M41 is connected with antenna M40, analog to digital converter M422, aerial signal receiver M423 and ground protection port M424 respectively, and the different connection status according to antenna M41 can produce different magnitudes of voltage.The user can arrange respectively each self-corresponding range of voltage values of different antennae state according to the observation circuit setting of antenna condition observation circuit module M41 and the connection status of antenna M40.
After communication module M42 opened, the power supply M411 of antenna condition observation circuit module M41 namely began power supply; Antenna condition observation circuit module M41 satisfies condition of work, can produce immediately a burning voltage; Analog to digital converter M422 reads this burning voltage, after carrying out mould/number conversion, the analog voltage that reads is converted to digital voltage value.
For example, getting power supply M411 magnitude of voltage is the 2.8V(volt), resistance R 1=15Kohm(kilohm), R2=15Kohm, R3=15Kohm, R0=10kohm, inductance L 1=47nH(nanohenry), C1=33pF/50V(represents that capacitance is 33 pico farads, maximum pressure-bearing is 50 volts).
When antenna normally connects, connection status of antenna M412 place is channel status, according to the observation circuit setting of antenna condition observation circuit module M41, and the value of each element in circuit, can draw the magnitude of voltage of this moment, formula is as follows:
VADC=2.8V*[(R3//?R0)÷(R1+R3//?R0)]
=2.8*[6÷(15+6)]V

=800mV
Wherein, R3//R0 represents the resistance total value that R3 is in parallel with R0.Magnitude of voltage VADC is exactly the magnitude of voltage that analog to digital converter M422 port reads is got, and analog to digital converter M422 converts 800mV to corresponding digital voltage value 01100100000.
In the present embodiment, the comparison agreement of CPU module M421 agreement is as shown in table 1.CPU module M421 calls 01100100000 according to after relatively agreement compares computing, and output numerical value 0 is to the control section M431 of upper strata teller console M43.
| ADC read value (mV) | Phenomenon | The software result |
| 600-1000 | Antenna connects normal | +CANT:0 |
| Less than 200 | Antenna is shorted to ground | +CANT:1 |
| 1200-1600 | Antenna is not installed or is not installed | +CANT:2 |
| Greater than 2000 | Antenna is shorted to other power supplies | +CANT:3 |
Table 1: the comparison agreement of agreement
Control section M431 designs based on single-chip microcomputer, after receiving the numerical value " 0 " that CPU module M421 reports, sends antenna according to single-chip microcomputer inner setting program to state indicating device M432 and connects normal state indication, and the indicating status indicating device carries out corresponding operating.Give a green light as point, the expression antenna connects normal.
When antenna connection status M412 place has been shorted to ground for antenna, this moment, the dividing potential drop resistance of antenna condition observation circuit changed, the magnitude of voltage that remote effect read to analog to digital converter M422, and VADC voltage at this moment can directly be derived as 0V.Compare agreement according to table 1, this moment, CPU module M421 can report numerical value " 1 " to control section M431, but control section M431 indicating status indicating device M432 carries out corresponding operating.As light amber light, representative antennas is shorted to ground.
When antenna was not installed or do not install, connection status of antenna M412 place was open-circuit condition, and the magnitude of voltage of this moment can be drawn by following formula:
VADC=2.8V*[R1÷(R1+R3)]
=2.8*(15÷30)V
=1.4V
Compare agreement according to table 1, CPU module M421 should report numerical value " 2 " to control section M431, but control section M431 indicating status indicating device M432 carries out corresponding operating.Send out a warning as point, representative antennas is not installed or is not installed.
When antenna connection status M412 place received other power supplies for antenna, concrete magnitude of voltage can be different because of the voltage that is shorted to voltage source, but can get the minimum voltage value of antenna condition observation circuit module M41.Calculate according to observation circuit, this moment, the minimum voltage value was to I haven't seen you for ages greater than 2V.So the magnitude of voltage that reads as analog to digital converter M422 is during greater than 2V, according to table 1 agreement relatively, CPU module M421 reports numerical value " 3 " to control section M431.The access of considering large power supply may cause damage to communication module M42, the specific interpolation protection scheme of program herein, closed communication module M42 when for example CPU module M421 reports numerical value " 3 ".But control section M431 indicating status indicating device M432 carries out corresponding operating, sends out a warning and notes with timely reparation to cause the user by the buzzing type of alarm as point.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
