Property, the equipment after above-mentioned conformity testing and verifying, after factory comes into the market can anti-interference ability with higher and
Reliability promotes user experience and brand influence.
In this regard, the present invention provides a kind of remote signal detection system, as shown in Figure 1, the detection system includes: host computer 1；
Signal processing unit 2 is communicated with host computer 1；Remote-control-signal reception unit 3 is communicated to connect with signal processing unit 2, is used
In receiving the first remote signal；Remote signal transmitting unit 4 is communicated to connect with signal processing unit 2, distant for emitting second
Control signal；First remote signal is the remote signal from remote controler and monitors first remote signal by host computer 1, at signal
The processing of unit 2 is managed by remote control command that host computer 1 is simulated to generate the second remote signal.
Specifically, the present embodiment is related to two aspects, on the one hand, emits the first remote signal by remote controler, passes through monitoring
Whether the corresponding movement generated of the first remote signal is correct to test the first emitted remote signal；On the other hand, pass through mould
The remote control command that quasi- remote controler issues, the remote control command can be correct or wrong, and it is distant to this to monitor equipment to be tested
The response or whether respond that control order is made, verify the reliability of the equipment, for evaluating the anti-interference ability of the equipment.
In the present embodiment, it for the ease of explaining and illustrating, is illustrated so that equipment to be tested is air conditioner as an example, it is certainly to be tested to set
Standby can be other electronic equipments that can be controlled by remote controler.
In the present embodiment, as shown in Figure 1, remote controler issues the first remote signal, which is infrared letter
Number, first remote signal is received using remote-control-signal reception unit 3, the present embodiment remote-control-signal reception unit 3 is infrared connects
Circuit, the specific a infrared receiver probe for using model HS0038 are received, the first remote signal received is input to signal
Processing unit 2 is handled and is sent to host computer 1 after parsing first remote signal, and software receives upload in host computer 1
Remote signal simultaneously can for example be shown by its display screen, such as air quantity, mode (such as heating mould are shown on display interface
Formula, refrigeration mode, dehumidification mode etc.), set temperature, the parameters such as timing, pass through the first remote signal that remote controler issues, it is corresponding
The parameter on the display interface of host computer 1 is monitored, whether the instruction that tester can quickly determine that the remote controler issues is correct.
Signal processing unit 2 uses such as UART(Universal Asynchronous Receiver/Transmitter, general different
Walk receiving-transmitting transmitter) serial communication and UART signal is issued through the signal processing unit 2 treated the first remote signal, because
This, as shown in Fig. 2, needing to be connected with interface conversion unit 5 between signal processing unit 2 and host computer 1, it is contemplated that on existing
Position machine 1 generally receives usb signal, and therefore, which can turn serial port unit for USB, is used for signal processing list
The rs 232 serial interface signal that member 3 issues is converted to the received usb signal of host computer 1, or the usb signal that host computer 1 issues is converted to
The received rs 232 serial interface signal of signal processing unit 3.Certain interface conversion unit 5 is also possible to wirelessly turn serial port unit, and being used for will
The rs 232 serial interface signal that signal processing unit 3 issues is converted to the received wireless signal of host computer 1, or the nothing that host computer 1 is issued
Line signal is converted to the received rs 232 serial interface signal of signal processing unit 3.Interface conversion unit 5 uses in the present embodiment
The conversion of USB to serial UART interface may be implemented in the interface conversion chip of FT232RL.
In the present embodiment, software can be simulated for example by its display interface and generate remote control command in host computer 1, this is distant
The remote signal that can be specified byte data in modified remote-control data packet and simulate generation error, remote control letter are ordered in control
It number is sent to signal processing unit 2, and the second remote control that is converted into air conditioner indoor unit by signal processing unit 2 and can identify is believed
Number, and launched by remote signal transmitting unit 4, the second remote signal of the present embodiment is infrared signal, corresponding remote control
Signal transmitter unit 4 is infrared transmitting circuit, is sent for the infrared signal after converting signal processing unit 2, and by
Indoor unit receives.Due to the infrared remote-controlled signal that indoor unit receives be it is modified after remote control command, tester
Member can receive the movement after the remote signal according to air conditioner indoor unit, to evaluate air conditioner anti-interference ability and reliability
Whether can be operated normally after degree, such as the remote signal of air conditioner reception mistake.Similarly, if the simulation hair of host computer 1
Telecommand out is usb signal, then needs that usb signal is converted to UART signal by interface conversion unit 5 and be sent to letter
Number processing unit 2, or if the telecommand that host computer simulation issues is wireless signal, need to pass through interface conversion unit
Wireless signal is converted to UART signal by 5 is sent to signal processing unit 2.In practice, remote controler huge number, function is not yet
It is unified, all remote controler and air conditioner indoor unit matching test can not can be easy to simulate a variety of remote controls by 1 software of host computer
Signal, the error signal issued for example including insufficient by external interference or self electric quantity realize the room of analog telecommand device signal
Interior machine test, greatly facilitates tester, improves testing efficiency and test is comprehensive.
In the present embodiment, as shown in Fig. 2, in order to indication signal processing unit 2 working condition, be provided with at signal
The indicating circuit unit 6 that unit 2 communicates to connect is managed, in the present embodiment, signal processing unit 2 uses R5F101FCAFP model
Integrated chip, indicating circuit unit 6 is concatenated pull-up resistor and the LED light being connected at the data line interface of the chip.
The specific detection process of said detecting system can be with reference to Fig. 3 and flow chart shown in Fig. 4 and below to the two
The description of flow chart.
Two aspects as described above respectively correspond the test pattern and Validation Mode of detection method.Test pattern is for surveying
Whether correct try the first remote signal that remote controler issues；Validation Mode is used to receive the remote control letter of mistake in equipment to be tested
Number when verify equipment to be tested to the anti-interference ability of error signal.
In conjunction with the structure of Fig. 1 and Fig. 2, Fig. 3 and Fig. 4 are described respectively.In the present embodiment, as shown in figure 3, remote signal connects
Receive unit 3 receive remote controler send the first remote signal, signal processing unit 2 receive the first remote signal and parse this first
Remote signal, the first remote signal after parsing is sent to host computer 1, and monitors first remote signal pair by host computer 1
The movement that should be generated.Also, signal processing unit 2 exports UART signal, and host computer 1 receives usb signal, therefore, in host computer 1
The interface conversion unit 5 being arranged between signal processing unit 2 is used for the conversion of usb signal and UART signal.
As shown in figure 4, host computer 1, by its software analog telecommand order, which can be one kind and for example passes through
Remote control command wrong obtained from specified byte data in remote control signal data packet is modified, which passes through signal processing
It is sent after the processing of unit 2 at the second remote signal, and by remote signal transmitting unit 4, indoor unit can recognize at this time
Second remote signal, observation indoor unit whether normal operation or state when acceptance error remote signal, verify air conditioner
Reliability.
