Detailed Description
Various examples of the invention are described below with reference to the drawings, wherein like reference numerals represent like elements. The following description of the various embodiments is provided to enable those skilled in the art to make a thorough understanding of the present invention and is intended to be exemplary rather than limiting. The drawings of the various elements, components, modules, devices and apparatus bodies in the figures are not necessarily to scale, but rather are intended to show the relative relationships among the elements, components, modules, devices and apparatus bodies.
FIG. 2 is a flow chart of an alarm device calibration method according to one embodiment of the invention. The calibration method is applied to the alarm device, and after the alarm device is installed for the first time, the alarm device can be calibrated by the method shown in fig. 2, so that the communication between the alarm device and the alarm receiving center is normal. Also by way of example, the calibration method shown in fig. 2 can also be carried out during routine maintenance of the alarm device.
At step 20, a signal is sent by the alarm device to a remote alarm receiving center. The alarm device is, for example, an alarm host provided on the site. In a specific example of the invention, the alarm master communicates with the alarm centre via a telephone network, but the invention does not exclude that the alarm master communicates with the alarm centre via a 2G/3G/4G network.
In step 21 the alarm device receives a feedback signal for said signal.
In step 22, after the alarm device receives the feedback signal for the signal, analyzing the feedback signal, and if the analysis result indicates that the signal sent by the alarm device is not normally transmitted to the remote alarm receiving center, proceeding to step 24; otherwise, go to step 23; in this context, the failure to transmit normally refers to a situation where the signal sent by the alarm device is not transmitted to the alarm receiving center, and there are various reasons that the signal sent by the alarm device fails to reach the alarm receiving center normally, which are not listed.
In step 24, the anomaly occurrence point where an anomaly occurred during the signal transmission process is analyzed, wherein the signal is the signal sent by the alarm device to the remote alarm receiving center. Illustratively, the signaling process includes a handshaking phase of the alerting device with the called party, a communication phase with the alarm center. The handshake phase may be divided into more detailed phases, such as a dialing sub-phase of the alarm device, a response sub-phase of the dialed party, and so on.
In step 26, parameters associated with the analyzed anomaly occurrence points are adjusted and based on the adjusted parameters, a signal is again sent by the alarm device to the remote alarm center. Illustratively, the parameters associated with the handshake phase include a dialing duration, a dialing amplitude, a dialing width, a dialing interval when the alarm device dials, a response duration of the called party, a first frequency signal response duration, and a second frequency signal response duration.
According to an example of the present invention, after the signal is sent to the remote alarm receiving center again in step 26, step 21 is executed again, and the alarm device receives the feedback signal for the sent signal again and executes the subsequent steps in turn. If the analysis result confirms that the signal sent again by the alarm device is not normally transmitted to the remote alarm receiving center in the step 22, the step 24 and the following steps are continuously executed; otherwise, step 23 is executed to end the execution of the method.
Fig. 3 is a schematic structural diagram of an application environment of the calibration method for an alarm device according to a specific example of the present invention, wherein the alarm device 30 is an alarm host, and therefore, in the following description, the alarm device is also directly referred to as the alarm host 30. Fig. 4 is a flow chart illustrating a complete interaction between the alarm host 30 and the alarm receiving center 32 in fig. 3, and more particularly, illustrating a complete process of the alarm host 30 sending an alarm signal to the alarm receiving center 32 and receiving feedback from the alarm receiving center 32. Fig. 5 is a process schematic of the transmission and response of the signals of the alarm master 30 and the alarm receiving center 32. The process shown in fig. 5 corresponds to the flow shown in fig. 4, the lower part of fig. 5 is a process schematic of the alarm host 30 sending a signal to the alarm receiving center 32 and receiving a feedback signal from the alarm receiving center 32, and the upper part of fig. 5 is a process schematic of the alarm receiving center 32 receiving a signal and sending a feedback signal. The interaction process between the alarm host and the alarm receiving center of the alarm is described below with reference to fig. 3, 4 and 5.
At step 40, alarm host 30 receives an alarm indication, such as a security device. At step 42, the alarm host 30 detects the dial tone before dialing to confirm whether the dial tone exists after the switch is dialed when the called party is accessed, and the time of the dial tone, the dial tone time a, in the case of the dial tone. In step 44, the alarm host 30 dials in dual tone multi-frequency DTMF; the parameters involved include the amplitude q of the keys in dialing, the duration k of each key, and the time interval m between two keys. At step 46, the alarm host 30 waits for a response from the called party; the relevant parameter in this step is the waiting time b for the alarm host 30 to wait for the called party to respond, or the response time b for the called party. At step 48, the alarm host 30 receives a first frequency signal transmitted by the dialed party at a first frequency; wherein the first frequency is 1400Hz, and the duration c of the first frequency signal is the related parameter in this step. At step 50, the alarm host 30 receives a second frequency signal transmitted by the dialed party at a second frequency; wherein the second frequency is 2300Hz, and the duration e of the second frequency signal is the relevant parameter in the step. There is an interval time d between the first frequency signal and the second frequency signal. At step 52, the alarm host 30 sends a report to the alarm receiving center 32, the report being in DTMF format. In step 52, the parameters involved include the amplitude r of the keys at which the alarm host 30 sends the report, the duration n of each key, and the time interval p between two keys. There is a time interval f between the second frequency signal and the report being sent by the alarm master 30. At step 54, alarm host 30 receives a third frequency signal transmitted by alarm receiving center 32 at a third frequency. In step 54, the duration of the third frequency signal is h. There is a time interval g before alarm master 30 reports an end and a third frequency signal is sent. At step 56, the alarm host 30 sends a DTMF format report to the alarm receiving center 32. There is a time interval j after the third frequency signal before the DTMF format report is sent again by alarm master 30.
The interaction process described above is illustrated without any exception in the communication between the alarm host 30 and the alarm receiving center 32. The interaction process can be roughly divided into two stages, namely a handshake stage of the alarm host 30 and the called party, and a communication stage of the alarm host 30 and the alarm receiving center. It should be noted that, here, the called party may be a switch of the call network where the alarm host is located; in some application scenes without a switch, the alarm system can also be other switching equipment accessed for realizing the conversation between the alarm host and the alarm receiving center; in addition, the situation that the called party is the alarm receiving center itself is not excluded.
Referring to fig. 5, the detection time a, the amplitude q of the keys during dialing, the duration k of each key, the time interval m between two keys, the response time b, the duration c of the first frequency signal, the duration e of the second frequency signal, the interval d between the duration c and the duration e, the amplitude r of the keys during the report transmission of the alarm host 30, the duration n of each key, the time interval p between two keys, the time interval f between the second frequency signal and the report transmission of the alarm receiving center 32, the duration h of the third frequency signal, the time interval g between the end of the report of the alarm host 30 and the transmission of the third frequency signal, and the time interval j between the DTMF format reports transmitted by the alarm host 30 after the third frequency signal, which are mentioned in the above interaction process, are all when the signal transmitted by the alarm device cannot be normally transmitted to the alarm receiving center, the parameters of the adjustment may be taken into account.
Referring back to fig. 2, in step 24, an abnormality occurrence point at which an abnormality occurs during signal transmission is analyzed. In the case that the signal sent by the alarm device is not transmitted normally, the alarm device may receive a feedback signal that the signal is not sent normally. Based on the feedback signal, it is possible to analyze which node or stage in the process shown in fig. 5 is abnormal. And adjusting parameters related to the analyzed abnormal occurrence points according to the analysis result, and sending a signal to a remote alarm receiving center by the alarm equipment again based on the adjusted parameters.
For example, assuming that the analysis result indicates that the response time of the alarm host 30 waiting for the called party is too long in the process shown in fig. 4, that is, the response time b shown in fig. 5 is timed out, the time of the alarm host 30 waiting for the response time is adjusted to be a little longer, so that the alarm host 30 can tolerate a longer response time of the alarm receiving center.
Illustratively, assuming the analysis indicates that an anomaly has occurred in step 52 shown in FIG. 4, the parameters associated with this phase, i.e., the amplitude r of the key at which the alarm host 30 shown in FIG. 5 sends a report, the duration n of each key, and the time interval p between two keys, e.g., the duration is adjusted to be shorter or longer, are adjusted. How this is specifically adjusted depends on the actual analysis result.
In this manner, the alarm host 30 may automatically perform a calibration process in the event of an abnormality in the alarm process. Specifically, firstly, analyzing the stage at which the abnormal problem is generated, and further adjusting corresponding parameters; and then, based on the adjusted parameters, generating a new alarm signal and sending the new alarm signal to an alarm receiving center again.
FIG. 6 is a schematic diagram of an alarm device calibration system according to an example of the invention. The calibration system is provided in an alarm device, such as the alarm master 30 described above in connection with fig. 3. The calibration system comprises a transmitting unit 60, a first analyzing unit 62, a second analyzing unit 64 and a signal re-transmitting unit 66.
The transmitting unit 60 is used for transmitting signals to a remote alarm receiving center, such as the alarm receiving center 32 shown in fig. 3. The first analysis unit 62 analyzes the feedback signal for the signal after the alarm device receives the feedback signal. If the analysis result of the first analysis unit 62 indicates that the signal sent by the alarm device is not normally transmitted to the alarm center, the second analysis unit 64 analyzes an abnormal occurrence point where an abnormality occurs in the signal transmission process. The signal re-sending unit 66 is used for adjusting the parameters related to the abnormal occurrence point and sending the signal to the remote alarm receiving center again based on the adjusted parameters. Wherein, the second analysis unit 64 analyzes the signal transmission process and comprises a handshake stage of the alarm device and the called party and a communication stage of the alarm receiving center. In correspondence with the analysis process of the second analysis unit 64, the signal reissuing unit 66 is arranged to adjust parameters associated with the handshake phase, including the dialing duration, the dialing amplitude, the width, the interval when the alarm device is dialing, and to adjust one or more of the response duration of the called party, the response duration of the first frequency signal, the response duration of the second frequency signal. The signal re-transmission unit 66 is further arranged to adjust one or more of the parameters associated with the communication phase of the alarm centre including the amplitude, width, interval of the alarm master reporting to the alarm centre after the handshake phase, and the duration of the third frequency signal from the alarm centre.
By way of example, in the application environment shown in FIG. 3, the alarm device calibration method shown in FIG. 2 may be performed using the alarm device calibration system shown in FIG. 6. It should be noted that the alarm device calibration system shown in fig. 6 and the alarm device calibration method shown in fig. 2 are not necessarily used in combination, and they can be applied to the alarm device independently.
At step 20, a signal is sent by a sending unit 60 provided in the alarm device 30 to the remote alarm receiving center 32. In step 21, the alarm device 30 receives a feedback signal for said signal. In step 22, the first analysis unit 62 provided in the alarm device 30 analyzes the feedback signal, and if the analysis result indicates that the transmitted signal is not normally transmitted to the remote alarm center 32, the process proceeds to step 24; otherwise, go to step 23. In step 24, the second analyzing unit 64 provided in the alarm device 30 analyzes an abnormality occurrence point at which an abnormality occurs during signal transmission. The signaling process has been described in detail above and is not repeated. In step 26, the signal retransmission unit 66 adjusts the parameters associated with the analyzed abnormality occurrence points and retransmits a signal to the remote alarm receiving center 32 based on the adjusted parameters. In step 26, after the signal retransmission unit 66 retransmits the signal to the remote alarm receiving center 32, step 21 is performed again, and after the alarm device receives the feedback signal for the signal, the subsequent steps are performed sequentially by the alarm device calibration system.
According to the invention, in the calibration process of the initial installation stage of the alarm device, if the alarm signal sent by the alarm device cannot be normally transmitted to the alarm receiving center, the alarm device calibration method or the alarm device adopting the alarm device calibration system can automatically analyze so as to automatically calibrate the corresponding parameter, and then resend the signal. In the maintenance process of the alarm equipment, the alarm equipment can be automatically calibrated by the alarm equipment calibration method or the alarm equipment calibration system, and the alarm equipment is further maintained to ensure that the signals sent by the alarm equipment can be normally transmitted to an alarm receiving center.
In addition, although the present invention has been described above with reference to an alarm host as a specific example of an alarm device, the alarm device may be other components that can be combined with a security system and perform an alarm. Also, the manner in which the alerting device dials the called party may be other than DTMF, such as CFSK.
The calibration method for the alarm device according to the present invention can be implemented in the alarm device through software, hardware or a combination of software and hardware, and in any way, for the convenience of the user, a key or other operable element can be arranged on the alarm device, so that the user can execute the calibration method by operating the key or the operable element. Further, the alarm device calibration system according to the present invention may also be implemented as a software module, a hardware module, or a combination of both. Similarly, a key or other operable element may be provided on the alarm device such that a user may operate the alarm device calibration system by operating the key or operating element.
