Description

Sequentially triggered alarm method and system

The present invention relates to a method and system for triggering a sequence alarm, and more particularly to a technique for determining an alarm level by sequentially triggering a plurality of alarms provided in a security location.

In the case of a security system, a sensor is usually installed near the entrance and exit of the occasion to detect the entry and exit of the scene; and an intrusion can be set near the portal that can enter and exit the place. The sensor, therefore, a specific host in the security system can receive the signal of the sensor at each location to determine whether there is a message entered at an inappropriate time.

In a conventional security system, as long as a particular sensor senses an action that may involve security, such as when there is an ingress and egress behavior at a location that cannot be entered, the camera may still be located unless a camera is provided there. It is impossible to interpret whether there is an illegal intrusion, or even to determine any malfunction. In any case, it is still necessary to send personnel to deal with it to ensure safety.

Moreover, the prior art does not propose any solution to determine appropriate security measures based on the security system installed in a specific occasion, which may result in waste of personnel and time.

The reason is that the present inventors have felt that the above problems can be improved, and that the present invention has been deliberately studied and used in conjunction with the theory, and a present invention which is reasonable in design and effective in improving the above problems has been proposed.

The present invention relates to a method and system for triggering a sequence alarm. The security technology described in the disclosure of the invention is mainly capable of determining an alarm level by judging the sequence of time and time difference between triggers of multiple sensors, so that appropriate protection measures can be performed correspondingly, or It is possible to judge the alarm of a malfunction, thereby making the security system more efficient.

According to an embodiment, the sequential triggering alarm system disclosed by the present invention determines an alarm level according to a situation in which a plurality of alarms disposed in a security location are sequentially triggered. According to an alarm policy, the determination of the alarm level may be based on multiple sensors. The triggered sequence determines the corresponding alarm level, and can also be included in the position of different sensors to determine the time difference before and after being triggered.

The main technical flow of the method for sequentially triggering the alarm is that the first host receives the first sensing signal and starts timing at the same time. After a time interval, the security host receives the second sensing signal, and can determine an alarm level according to the time interval.

In this technical concept, if the time interval between the first sensing signal and the second sensing signal exceeds a time threshold, the alarm level is no alarm, and the time threshold should be set according to the actual situation of the security facility. Can exclude invalid security events. If it is determined to be a malfunction, the second sensing signal can be set as the first sensing signal, and on this basis, waiting to receive the next sensing signal.

If the time interval is within the time threshold, that is, a valid alarm is generated, including performing one of the beeping, the activation signal, and the notification of one of the control center dispatchers or a combination thereof.

According to another embodiment of the method for sequentially triggering an alarm according to the present invention, the alarm level is determined according to a plurality of sensing signals, and the step includes: receiving, by the security host, the first sensing signal and starting timing, and then determining whether it is at the first time threshold. Receiving the second sensing signal, if it is not receiving the second sensing signal in the first time threshold, indicating that there is no valid security event, that is, resetting the timer and re-receiving the first A step of sensing the signal.

However, if the second sensing signal is received in the first time threshold, it is determined whether an alarm level is reached. The determination of the alarm level may be based on a preset alarm policy, so that the alarm level can be determined according to whether the alarm level meets any need. The alarm level of the report. If the alarm level to be reported has been reached, an alarm message is sent according to the alarm level; if the alarm level to be reported has not been reached, it continues to wait for the third sensor to be received.

The subsequent steps will be repeated. First, it is determined whether the third sensing signal is received after the second sensing signal in the second time interval. If the next sensing signal is not received within the time interval, it may still be a malfunction; otherwise, The alarm level is determined based on the order of the three sensing signals.

In the embodiment of the sequential triggering alarm system, the system is composed of at least two sensors located at different positions and a security host, and the security host can determine the alarm level according to the sensor trigger sequence and time of different positions.

The security host includes a control unit for managing the operation of each circuit unit in the maintenance host, an input interface unit for receiving the sensing signal generated by the sensor, a time interval calculated according to the plurality of sensing signals, and an alarm level for determining an alarm level by an alarm policy. Unit, and a reporting unit that generates an alert message based on the alert level. It can also include a communication unit that transmits an alert message to the control center.

FIG. 7 shows a second flow of an embodiment of the method for sequentially triggering an alarm according to the present invention.

According to the sequence triggering alarm method and system embodiment disclosed in the disclosure, the sequential triggering alarm system can refer to the following figures and descriptions, in particular, to provide a front-to-back triggering sequence according to the plurality of sensors designed in one case. The time determines the corresponding alarm level. The alarm level will set an alarm policy according to the characteristics of the occasion. For example, when the specific alarm level is met, a beep, a start signal, or a signal is sent to the security control center to dispatch the security personnel. To the scene and other measures.

The location to which the present invention is applied will be provided with at least two perceptrons, as shown in FIG.

The indoor plan view 10 shown in the figure is provided with a plurality of sensors 101, 102, 103, 104, 105, 106, such as at the entrance 12, the window and the important position in the room, such as a reed switch, a photo interrupter, and an image sensor for judging the intrusion by image change. The main purpose of the weight sensor is to be able to sense the incoming and outgoing objects, and to install the appropriate sensor in accordance with the characteristics of the occasion. In the designed alarm strategy, it is determined that the ingress and egress of the illegal entry range and time are sensed. The corresponding alarm level of the object.

As shown in the figure, the sensors 101, 102, 103, 104, 105, 106 are set at different positions, and the system will obtain a plurality of sensor sequences that will be triggered sequentially through the possible moving lines of the simulated personnel, because the distance between the sensors will affect both of them being triggered. The time difference, together with the allowable time range, the habit of the illegal intruder, the perceptron characteristics, etc., set the relevant alarm strategy.

The security technology described in the invention discloses that the alarm level corresponding to the time difference is determined by determining the sequence of the plurality of sensors being triggered, so that appropriate security measures can be performed correspondingly, or an alarm of the malfunction can be determined, thereby allowing the security system to operate. more efficient.

2 is a schematic diagram showing an embodiment of the sequential triggering alarm system of the present invention. The figure shows that three sensors are provided in a specific occasion, and the actual implementation is not limited to a specific number, but preferably two or more. This example shows that the first perceptron 201, the second perceptron 202, and the third perceptron 203 are respectively connected to the security host 22 responsible for processing the perceptual signals generated by the perceptrons.

The security host 22 can be located near or at a remote location, and each sensor (201, 202, 203) can be connected through a general cable, a wired network (such as a regional network) or a wireless network. The signal will be modified according to the connection method. For example, the general cable can transmit the signal by analog signal. If the network connection is used, the location of the security host 22 may be located at the other end of the network. The signal will be carried in digital packets.

The security host 22 is suitable for the sequential triggering alarm system disclosed in the present invention. The circuit function includes at least a receiver 221 electrically connected and receiving each sensor signal. The memory unit 225 includes a memory body necessary for the host 22 to operate. The associated temporary storage memory for recording the received sensing signal, such as the associated alarming policy, can be recorded in the memory of the memory unit 225, including a plurality of triggering sequences of at least two sensors, when the system wants to determine the alarm level. The alarm level can be determined according to the time interval between the triggering sequence recorded in the memory and the sensing signal generated by each of the sensors.

The timer 223 calculates the time at which the sensing signal is received, so that the security host 22 can calculate the time interval between different sensing signals. When the sequential triggering alarm program of the present invention is started, it is preferable to start the timer 223 when the first sensing signal is received, and reset the timer 223 when the system setting returns to the initial state.

The security host 22 can be provided with a plurality of transmitters 222. When the system determines that a specific alarm program should be activated, it will be correspondingly reported according to the alarm policy set in a specific occasion, for example, the buzzer, the light signal or the transmission signal can be activated to the remote control. The center or a specific person, or a combination of these reporting methods.

The security host 22 is provided with a communication module 224 that can be connected to a remote control center. The communication mode can be determined according to design, including general network lines, wireless communication, telephone lines, and the like. When the system determines that a specific alarm level should be activated, the signal can be selectively transmitted through the communication module 224, or the message can be recorded on the remote server for later query.

According to the embodiment, in this example, the first sensor 201, the second sensor 202, and the third sensor 203 are disposed at different positions according to the characteristics of the set occasion, such as doors and windows, entrances and exits, important facilities, and the like. The designed position can be designed to simulate the path when the intruder 20 enters the occasion. The first sensor 201, the second sensor 202 and the third sensor 203 have a certain distance. For example, the distance between the first perceptron 201 and the second perceptron 202 is d1, and the distance characteristic and the path characteristic (such as the need to cross the obstacle, bypass) are redesigned for a certain time range t1; the second perceptron 202 is The distance between the third perceptrons 203 is d2, and the corresponding time range is t2.

When the intruder 20 enters the situation, the first perceptron 201, the second perceptron 202, and the third perceptron 203 may be triggered in sequence, and the security host 22 will sequentially receive the sensing signals of the three perceptrons. Therefore, the alarm level can be judged by the time difference in which two or three perceptrons are triggered. In particular, each situation may have different alarm strategy designs due to different site characteristics, and the number of sensors and the location of the settings, including the sequence in which they are triggered, may be different.

The aforementioned alarm levels are false alarms, general alarms, dangerous alarms, or emergency alarms that require immediate dispatch or alarm.

As shown in the embodiment shown in FIG. 3, the security host 30 proposed by the present invention is shown in addition to contacting a specific number of perceptrons (in this example, the first perceptron 301, the second perceptron 302, and the third perceptron 303). In addition, it can communicate with the control center 32 through the network 3, including transmitting signals under specific alarm levels. The control center 32 will perform corresponding security measures, such as recording and continuously collecting related information, dispatching personnel, dispatching patrol cars, alarms, etc. may.

The design of the security host 30 can be a computer system with an alarm level determination function. In accordance with another embodiment, the alert level can also be determined by the remote control center 32. For the design of the security host 30, reference may be made to the functional block diagram of the embodiment of the sequential triggering alarm system of the present invention shown in FIG.

The security host 30 connects at least two perceptrons, and the security host 30 sequentially receives the sensing signals generated by the at least two perceptrons in the triggering sequence. This example displays the first perceptron 301, the second perceptron 302, and the third sensing. The actual application can be changed according to the designed location.

The circuit function of the security host 30 according to the implementation of the present invention may include a control unit 401 for managing the operation of each circuit unit in the host 30 and a circuit unit electrically connected to the control unit 401, and mainly includes an input interface unit 403. The input interface unit 403 is a hardware interface for connecting an external device, such as a network interface, a telephone line interface, and the like, and does not exclude various terminals for receiving signals for receiving from the sensors (301, 302, 303). The resulting perception signal.

The security host 30 includes an alarm level determining unit 402 implemented by a hardware circuit or a software, and the alarm level determining unit 402 can calculate the time interval calculated according to the sensing signals generated by the at least two sensors processed by the control unit 401, or An alarm level is used to determine an alarm level. The alarm level has different designs according to the operation of the actual system. The alarm level may include false alarms, general alarms, dangerous alarms, or emergency alarms that require immediate dispatch or alarm.

The transmitting unit 404 in the security host 30 generates a corresponding alarm message according to the foregoing alarm level, for example, an alarm sound can be sounded by the buzzer 441, or a warning light is generated by using the light number 442 for the purpose of causing the trespasser. It has a certain deterrent effect and is used to notify relevant personnel to come to the scene for processing. According to the alarm level, an alarm message can be generated through the network 3 through the communication unit 405 in the security host 30, for example, by an alarm message to a control center, such as the control center 32 of FIG. 3, and the control center 32 performs appropriate security. Measures.

The method for operating the sequential triggering alarm system disclosed in the foregoing invention, according to the main technical features thereof, mainly includes receiving the sensing signal by the security host first, and if so The sensing signal is generated and received after a period of time, and can be set as the first sensing signal, that is, the system will start the sequence triggering alarm program, including starting a timer and waiting to receive the next sensing signal (second sensing signal). . In an embodiment, an alarm policy can be compared by an interval between two sensing signals to determine an alarm level, perhaps because the time interval is too long or a second perception is not generated at a preset time threshold. Signals, these can be a level without an alarm (such as a malfunction); if the next sensing signal is received within the threshold, indicating a valid alarm trigger, an alarm level is determined.

In another embodiment, the system may determine the alert level based on the third sensed signal received in another time threshold, as disclosed in the following embodiments. Related implementation aspects can be derived to determine an alert level for overall security measures based on signals generated by more perceptrons.

If it is determined in the program that the trigger event is a false alarm, the timer will be reset, and the first sensing signal is reset, and a new sequential triggering alarm program is started. The main inventive features can be seen in the flow shown in FIG.

In step S501, the security signal received by the specific host is detected as a first sensing signal, and in step S503, the timer is started to start timing. The system will start a sequence triggering alarm according to the specific designed alarm policy of the set security location, including the time threshold design between the two sensing signals. If, as in step S505, the security host receives the second sensing at the next time. The signal, when the time interval is calculated, in step S507, the circuit or software program in the security host will determine an alarm level according to the time interval and according to the alarm policy, as in step S509. The system will then make a corresponding report or related security measures based on the level of alert determined.

One of the embodiments of the method for sequentially triggering the alarm according to the present invention shown in FIG. 6 is implemented.

Beginning with step S601, the system is in a standby state, that is, the security host will be in a state of being received by the sensing signals generated by the respective sensors. When step S603 As described above, when the security host receives the sensing signal from the specific sensor, if the timer has been reset previously, the sensing signal can be set as the first sensor signal in an alarm program.

In step S605, the signal will be recorded to the memory first, and the timing is started, as in step S607. When the system starts counting, in step S609, the system will stand by to receive the next sensing signal to determine whether to receive the next sensing signal (the second sensor signal) within a time threshold. If the second sensor signal is not waited within a certain time threshold (No), according to the alarm policy, the first sensing signal may be determined as a false alarm or an invalid trigger event. At this time, the timer is reset and the system enters the standby state. And deleting the record of the temporary storage, as in step S611. In another embodiment, the sensing signal may also be stored in the security host memory for a period of time for checking.

If the next sensing signal (the second sensor signal) is received within the set time threshold, in step S613, in this embodiment, the triggering event may be determined as a valid trigger according to the alarm policy, and thus the alarm will be based on the alarm. The policy determines an alert level. The alarm level may be associated with an alarm measure. In step S615, it is first determined whether the alarm level reaches any alarm level. If it is determined that the specific alarm level is met, then in step S617, an alarm message, including sound, light, or Notify the relevant personnel or notify the control center to make specific preservation measures.

If it is judged to be a valid alarm, it is still not required to be reported at this time according to the alarm policy (No), indicating that the program needs to confirm the alarm level by the next sensing signal. At this time, the program returns to step S605, at this time. The sensing signal is recorded, and the steps of continuing to count in step S607, determining whether to receive the next sensing signal in a time threshold, and the like, and determining the alarm level in step S613, may determine that the trigger event is still in progress. Restart the program for a malfunction. If it is determined that the trigger event is valid, the program will proceed according to the alarm policy until the alarm level that needs to be reported is determined in step S615, and an alarm message is sent, as in step S617.

Figure 7 then shows that the sequential triggering method of the present invention utilizes three sensing signals to determine Example flow for breaking the alert level.

The process also begins, as in step S701, the host is ready to receive the sensing signal. In step S703, when the first sensor signal generated by the specific sensor is triggered, the message is first recorded to the memory, as in step S703. Start timing, as in step S705. The invention needs to determine an alarm level according to the next or multiple sensing signals, instead of only reporting by one signal, wherein the number of sensing signals quoted will be determined according to the occasion, and the relevant alarm strategy will be The distance between the multiple sensors and the time difference are related to the design of the sequence.

Then, in step S709, it is determined by hardware or software means whether the next sensor signal is received in the first time threshold, and the first time threshold is related to the position of the sensor generated according to the first sensing signal, when the first The sensor is triggered and will be determined according to the design. The next (second) sensor trigger should be valid at the first time threshold to confirm that it is a valid trigger, otherwise it is a false alarm.

Therefore, if there is no next perceptron triggered in the first time threshold (NO), then in step S711, the timer and the record in the memory are reset, and the process returns to step S701.

If the next sensing signal (second sensing signal) is received within the set first time threshold (Yes), then in step S713, the system determines the alarm level, and then, as in step S715, determines whether the need to report has been reached. The alarm level, that is, if the current process needs to wait for the next sensing signal according to the alarm policy, it is necessary to continue to determine whether to receive the next sensor signal in the second time threshold. In step S719, the second time threshold is The time difference between the second sensing signal and the third sensing signal is set.

If the current process judges that the level to be reported has been reached (Yes), as in step S717, an alarm message is issued, and the process returns to step S711 to reset the timer and the record.

If it is necessary to wait for the next sensing signal (No), if it is determined in step S619, if the next (third) sensing signal is received in the second time threshold (Yes), then step S713 is continued to determine the alarm level. Similarly, if the alert policy is still displayed To wait for the next perceptual signal again, repeat steps S713, S715, S719, and so on.

If it is determined after a step of receiving the sensing signal that the alarm level to be reported has been reached, an alarm message is sent, as in step S717. Therefore, the present invention is applicable to a plurality of security applications that require two or more sensing signals to be reported. In particular, the sensing signals are generated by triggers of different locations, and the system and method described in the present invention will Multiple time intervals are preset according to the distance between the sensors at different positions, and different next time sensor positions can be corresponding according to the position at which the first sensing signal is generated, so there are different time interval designs, that is, different positions. The time interval between the triggering sequence of the plurality of sensors and the sensing signals generated by the respective sensors determines the alarm level.

Therefore, according to the program for sequentially triggering an alarm according to the present invention, the present invention can determine an alarm level according to at least two sensing signals, and accordingly perform corresponding security measures, wherein the method is applicable to a specific occasion, and can avoid one or a few The sensor signal sends out any alarm, which can avoid unnecessary waste of human and material ineffective alarms in specific situations.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
