Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, and "a" and "an" generally include at least two, but do not exclude at least one, unless the context clearly dictates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

It is also noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a good or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such good or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.

The alarm method is mainly suitable for meeting the rapid alarm requirements of users in the process of carrying out order distribution. For example, assuming that a user has a cargo transportation demand, the user sends a cargo transportation request to the server, and the server allocates a delivery person capable of providing the cargo transportation service to the user according to the cargo transportation request. After the delivery personnel arrive at the goods receiving place appointed by the user and complete the goods loading, the order delivery is started. At this time, if the user selects to take a vehicle for goods transportation together with the delivery person, the user will keep close contact with the delivery person during order delivery, and the delivery person will pose a potential threat to the personal safety of the user. If the user does not follow the delivery personnel to carry out order delivery together, or the user drives the vehicle to follow the goods transportation vehicle to carry out order delivery by himself, in the order delivery process, the user does not keep close contact with the delivery personnel, and the delivery personnel do not pose a potential threat to the personal safety of the user. Therefore, a need exists for a method that can identify whether a user has a potential threat and provide a quick alarm for the user with the potential threat, so as to ensure that the user can give an alarm quickly in the face of an emergency and provide a strong guarantee for the personal safety of the user. The following describes the alarm method according to the embodiment of the present application:

fig. 1 is a schematic flow chart of an alarm method according to an embodiment of the present invention. The alarm method can be applied to a server and mainly comprises the following steps:

101: and receiving an alarm request sent by the client in response to the awakening operation.

102: the method comprises the steps of obtaining first position information of a delivery person and second position information of a user in the process of delivering an order of the user.

103: and if the distance difference between the first position information and the second position information is smaller than a first threshold value, alarming to an alarming end.

The wake-up operation referred to herein may include: any of the following: the method comprises the steps of making a specific sound, pressing a set key on a user terminal and triggering a set shaking behavior on the user terminal, wherein the waking operation in the scheme does not comprise the waking operation needing a complicated operation process, such as calling and the like. The wake-up operation that emits a specific sound, for example, may be a voice wake-up operation, which is to wake up the client after the user speaks a wake-up word. Pressing a set key on the user terminal may include: a touch screen awakening operation and a physical key awakening operation. For example, the touch screen wake-up operation is that the user can wake up the client after touching the touch screen. The physical key wake-up operation is that the user can wake up the client after pressing a physical button (such as an on-off key, a volume key, a Home key, and the like) on the user terminal of the user installed with the client. The shaking behavior set for triggering the user terminal may be, for example, a shaking-to-shaking wake-up operation, where a user holds the user terminal with the client and can wake up the client after shaking. Through the simple awakening operation, the method is more suitable for the emergency situation that a user is inconvenient to alarm by dialing a telephone.

The wake-up operation in the client may be customized by the user through the client, for example, the user may simultaneously define the voice wake-up operation and the shake wake-up operation in the client according to the need of the user, so that the user may wake up the client through any one of the two defined wake-up operations.

For example, fig. 2 is a schematic diagram of an alarm system according to an embodiment of the present invention. As can be seen from the figure, the alarm system includes a user holding a user terminal, a distributor, a client installed in the user terminal, a server, and an alarm. If the user meets a dangerous condition and cannot touch the mobile phone, after the user shouts the voice awakening word of 'alarm', the client of the user is awakened, and the client sends an alarm request to the server. It is easy to understand that the wake-up word corresponding to the voice wake-up operation can be set by the user himself, for example, the wake-up word can be set to "alarm", "save", "110", etc. In the using process, when a user only speaks a wake-up word (for example, an alarm), the client can be awakened, and when the user speaks a long sentence containing the wake-up word (for example, hurry up to me alarm), the client can also be awakened, so that the awakening requirement of the user can be better responded.

In practical application, in order to ensure that an alarm request sent by a client is real and reliable, after receiving the alarm request, a server does not directly give an alarm to an alarm end, but determines whether to give an alarm or not after judging the current actual condition. As shown in fig. 2, during order distribution, when the user and the distribution personnel are in the same vehicle, a situation may occur that the distribution personnel threaten the personal safety of the user, and in such a practical situation, the server side may give an alarm.

It should be noted that, in the process of delivering an order, the user and the delivery person are in a moving state, and the corresponding positions at different times are different. In order to accurately judge whether the user and the delivery personnel are on the same transport vehicle in the delivery process, the server side needs to acquire the first position information of the delivery personnel and the second position information of the user at the same time. If the difference between the time when the server side acquires the first position information and the time when the server side acquires the second position information is large, the difference between the distances between the first position information and the second position information is too large, and the position relation between the user and the distribution personnel is not accurately judged. For example, assuming that the user and the distributor are in the same vehicle, when the speed is 100KM/h, but the difference between the two times is 1 second, the corresponding distance difference is detected to be about 27 meters, which is much larger than the first threshold (for example, the first threshold is typically 2 meters). Therefore, when the difference between the two location information acquisition times is large, the server needs to acquire the location information of the distribution personnel and the user again.

After the server judges and decides to alarm, the server can directly alarm the alarm end without the participation of a user in a specific alarm process, so that the alarm is more direct and efficient. The server side can also control the client side of the user to alarm, so that the alarm side can conveniently receive the latest alarm information of the user in real time, such as the latest on-site voice information, the latest on-site image information and the like.

As an alternative embodiment, a determination method for determining whether the user and the delivery person are on the same vehicle is provided. Fig. 3 is a schematic flow chart of a server side determination process, which includes the following steps:

301: inquiring the order which corresponds to the user identification and is being delivered; the first position information of the delivery personnel is the position information of the delivery personnel delivering the order; the second location information of the user is the location information of the user during the order distribution process.

302: and if the distance difference between the first position information and the initial address of the order is greater than a second threshold value, and the distance difference between the first position information and the second position information is smaller than a first threshold value, alarming to an alarming end, wherein the first threshold value is smaller than the second threshold value.

It is easily understood that the delivery orders are usually distributed and managed by the server, and the server stores the user identifier and the registration information of the delivery personnel corresponding to each distributed order, such as the name, contact address, home address, identification number, etc. of the delivery personnel. As can be seen from the foregoing, the alarm method according to the present application is mainly applicable to meeting the rapid alarm requirement of the user during the delivery order process. Therefore, after receiving the alarm request from the client, the server first needs to determine whether the user has an order being delivered. As an alternative embodiment, the specific way to determine whether the user has an order being delivered is as follows:

and the server side inquires whether the order of the user is contained in the currently distributed order or not according to the user identification contained in the received alarm request. If the server side does not inquire the order which is distributed for the user, the server side judges that the alarm request sent by the user belongs to misoperation or confirms that the alarm request is irrelevant to the current distribution service, and the server side ignores the alarm request. As an alternative, after the server ignores the alert request, the user terminal where the client is located may jump to a dial alert phone interface, for example, a "110" is displayed on the dial interface, and the user only needs to click the dial control to implement the alert. If the order which is delivered for the user is inquired, determining the delivery personnel which is currently delivering the order and the registration information of the delivery personnel.

After the server side inquires the order which is being delivered by the user, the server side needs to acquire the first position information of the current delivery personnel and the second position information of the user. After the server side obtains the first position information, a distance difference value between the first position information and the starting address of the order being delivered by the delivery personnel is further determined. And judging whether the delivery personnel leave the starting address to deliver the order according to the comparison result of the distance difference and the second threshold value. If the judgment result is that the distance difference between the first position information and the starting address of the order is not larger than the second threshold, the delivery personnel is considered not to start delivering the order, and whether the delivery personnel and the user are on the same transport vehicle or not does not need to be judged. If the judgment result is that the distance difference between the first position information and the starting address of the order is larger than the second threshold, the distribution personnel can be considered to start to distribute the order, and whether the distance difference between the first position information of the distribution personnel and the second position information of the user is smaller than the first threshold is further judged, so that whether the user and the distribution personnel are on the same transport vehicle or not is determined.

It should be noted that the first threshold value is used for determining whether the user and the delivery person are riding in the same transportation vehicle, and therefore, in order to avoid erroneous determination, the first threshold value cannot be too large (it is understood that the length of the vehicle cannot be exceeded), and for example, the first threshold value may be about 2 meters. The second threshold is used to determine whether the delivery personnel leaves the starting address for order delivery, and therefore, in order to avoid misjudgment, the second threshold cannot be too small, for example, the second threshold may be about 500 meters. The threshold size is only used as an example and does not constitute a limitation to the present application, and a user may set the sizes of the first threshold and the second threshold according to actual needs, and generally, the first threshold is smaller than the second threshold.

In practical applications, there may be a plurality of ways to determine whether the delivery person leaves the start address, for example, the server receives a request sent by the delivery person to leave the start address, so as to trigger the determination of the size relationship between the distance difference and the second threshold. And the position information of the distribution personnel can be acquired according to a certain sampling frequency, so that the relationship between the distance difference value and the second threshold value is triggered and judged.

After determining that the delivery person leaves the starting address, acquiring first position information of the delivery person and second position information of the user at the same time in the order delivery process. It should be noted that the same time may be understood as the same or similar time, so that the distance difference between the first position information and the second position information can be determined more accurately.

If the distance difference between the first position information and the second position information is larger than the first threshold, it can be considered that the distribution personnel and the user are respectively on different transport vehicles, that is, the distribution personnel cannot be in close contact with the user in the order distribution process, and the personal safety of the user cannot be threatened. If the distance difference between the first position information and the second position information is smaller than the first threshold value, the distribution personnel and the user are considered to be on the same transport vehicle, the distribution personnel may threaten the personal safety of the user in the order distribution process, and the server side gives an alarm to the alarm side. The alarm end can comprise an alarm end of a public security system and an alarm end where a service system is located.

According to the embodiment, the server side can judge whether the user has the potential threat according to the order distribution state and the distance difference between the first position information and the second position information, and a scheme for rapidly alarming the user with the potential threat is provided. According to the scheme, a corresponding alarm mode can be provided for the user more accurately, and the alarm right is prevented from being abused by the user while the alarm requirement of the user is met. Meanwhile, the alarm mode of the alarm device is simple and various, and the alarm requirements under different scenes are met.

As an alternative scheme, when the client sends an alarm request to the server, the client can automatically send the position information of the current position of the client, the alarm can be completed without the user participating in the alarm process, the alarm efficiency can be effectively improved, and the hidden alarm can be realized.

In practical application, the server may control the client to start the recording function, so as to obtain voice information of the sites where the user and the delivery personnel are located during the order delivery process. As an alternative, the voice information recorded by the client can be sent to the server in real time, so that the personnel at the server can know the current conditions of the user and the delivery personnel in time, and the voice information is stored in the server more safely.

If the client supports the image shooting function, the server can control the client to start the image shooting function, so that the server can obtain the image information of the sites where the user and the delivery personnel are located in the order delivery process. As an alternative, because the storage space of the client is limited, the image information shot by the client can be sent to the server in real time, so that the personnel at the server can know the current conditions of the user and the delivery personnel more timely and intuitively, and the image information can be stored in the server more safely.

It should be noted that the server referred to herein may be a local server or a cloud server cluster, so as to better serve the client.
