Description
Technical Field
The present application relates to the field of timeslot allocation technologies, and in particular, to a timeslot allocation method, a timeslot allocation device, an electronic device, and a computer-readable storage medium.
Background
A hospital bed card is a terminal that can display information and can be connected to a server through a gateway, and usually, a plurality of beds in a ward are provided, and each bed is provided with a bed card terminal. The bedside card can be used for displaying patient information, cautions and the like. The gateway serves as a transfer point between the head cards and the server, and one gateway can cover one or more areas of a plurality of head cards.
The bedside card and the gateway adopt a time-sharing working mode, and the working process among the bedside card, the gateway and the server is mainly divided into two steps, namely a registration process and a conventional heartbeat process.
First, the registration process is the process of acquiring the timeslot and acquiring the new communication key. The gateway broadcasts in a certain time slot within a heartbeat range of the terminal, the bedside card monitors the gateway broadcast after triggering registration (for example, by pressing a key), and sends a registration application to the gateway, and the gateway allocates a specific time slot and a key in a conventional heartbeat process to the terminal after determining that registration can be performed. In the conventional heartbeat process, the bedside card terminal performs heartbeat in the fixed time slot of the bedside card terminal and performs data interaction with the gateway, and if the probability that the gateway cannot respond after the heartbeat of the bedside card is higher, a re-registration process is triggered.
In the process of field arrangement of the bed card and the gateway, in order to ensure that all the bed cards are within the coverage area of the gateway, there will be some areas where the radio frequencies of the gateways intersect, as shown in fig. 1, areas ABC have ABC gateways respectively, and adjacent gateways have intersection areas. The bed card, registration and heartbeat processes in the intersection area are all affected by the other gateway. In addition, the cases of generating channel interference are 2, 3 and 4, and although the cases are not in the crossing range of the gateway, the cases of generating channel interference may occur because the three terminals of 2, 3 and 4 are close to each other.
For the first case, terminal 1 in the cross area may receive the broadcast of gateway a/B, and if terminal 1 registers with a successfully, then, terminal 1 will affect the reception of gateway B in the same timeslot every heartbeat.
For the second case, the respective gateways may receive the data sent by the terminals 2, 3, and 4, but if the terminals 2, 3, and 4 are assigned to the same timeslot, the reception of the terminals 2, 3, and 4 may receive interference, for example, the terminal 2 waits for a gateway to respond after heartbeat, and at this time, the terminal 3 sends heartbeat, and at this time, the terminal 3 affects the reception of the terminal 2 (although the same timeslot, there is a random delay before each heartbeat, so as to avoid complete synchronization of the terminal devices).

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 2, a flowchart illustrating steps of a time slot allocation method provided in an embodiment of the present application is shown, where the time slot allocation method may be applied to a server, and specifically may include the following steps:
step 101: receiving a first heartbeat signal sent by a first terminal; the first heartbeat signal is sent by the first terminal when accessing a first time slot of a target gateway, and the first heartbeat signal comprises a second heartbeat signal of a second terminal monitored by the terminal.
The method and the device for allocating the time slot of the terminal access gateway can be applied to a scene of allocating the time slot of the terminal access gateway.
The server may be used to allocate time slots of the gateway to the terminals. There may be multiple gateways under a server, each gateway may have multiple time slots, and the server side may manage the status of each gateway under it.
The first terminal is a terminal for accessing a gateway under the server, in this embodiment, the first terminal may be a mobile terminal, such as a mobile phone, a tablet computer, and the like, and in this embodiment, the first terminal is preferably a hospital bed card.
The second terminal is a terminal which is adjacent to the first terminal and has the same access gateway as the gateway to which the first terminal is to access or has a cross coverage area with the gateway to which the first terminal is to access. In this embodiment, the second terminal may be a mobile terminal, such as a mobile phone, a tablet computer, and the like, and in this embodiment, the second terminal is preferably a hospital bed card.
The first heartbeat signal is a signal sent by the first terminal when the first terminal needs to access the first time slot of the target gateway.
The second heartbeat signal refers to a signal sent by the second terminal when the second terminal accesses the target gateway or other gateways adjacent to the target gateway, which is monitored by the first terminal.
The first terminal will listen to the air signal in a heartbeat cycle when registering, and report to the uplink, which is divided into two cases: 1. when the first terminal registers with the target gateway for the first time, the first terminal can monitor and record the broadcast sent by the target gateway, so that the first heartbeat signal can be sent to the server. 2. When the first terminal is not registered with the target gateway for the first time, the first terminal may monitor and record a broadcast sent by the target gateway, and during this process, may also monitor heartbeat signals (i.e., second heartbeat signals) sent by other terminals.
If the terminal registered for the first time hears more than 1 gateway broadcast, the terminal is associated with the heard gateway and allocates a time slot, and if the time slot 1 is allocated, the associated gateway time slot 1 is in an unavailable state.
The terminal which is not registered firstly releases the time slot of the gateway which is related to the terminal and changes the terminal into an available state. Firstly, determining whether a mutual exclusion device exists, if the gateway registered this time is the same as the gateway registered last time, and the heartbeat information sent by other terminals is monitored in the time slot in which the heartbeat is carried out last time, the mutual exclusion device exists, and if the mutual exclusion device exists, the allocated time slot needs to satisfy the mutual exclusion relationship (which is the second situation of the interference situation); if the gateway registered at the time and the gateway registered at the last time are not the same and represent that the terminal moves, contacting the mutually exclusive relationship between the terminal and other terminals; if multiple gateway broadcasts are also monitored, the corresponding time slot associated with the gateway becomes unavailable.
After receiving the first heartbeat signal transmitted by the first terminal, step 102 is executed.
Step 102: comparing the first time slot with a second time slot contained in each second heartbeat signal; and the second time slot is sent when the second terminal accesses the target gateway or a gateway adjacent to the target gateway.
After receiving the first heartbeat signal sent by the first terminal, a time slot comparison may be performed between a first time slot included in the first heartbeat signal and a second time slot included in each second heartbeat signal, where the second time slot is a time slot sent by the second terminal when the second terminal is in an accessed target gateway or a gateway adjacent to the target gateway.
In this embodiment, the first time slot and the second time slot may be compared to determine whether the first time slot and the second time slot are the same.
After the time slot comparison is performed between the first time slot and each second time slot, step 103 is performed.
Step 103: allocating the target time slot of the target gateway to the first terminal according to the time slot comparison result; the target time slot is a time slot different from the second time slot.
The target time slot refers to a time slot in an available state acquired from the target gateway. The state of the time slot under each gateway under the server can be pre-saved in the server, as shown in table 1 below:
Table 1:
| time slot 1 | |
Time slot 3 | |
|
Time slot 6 | Time slot 7 | Time slot 8 | Time slot 9 | Time slot 10 | |
| Gateway A | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used |
| Gateway B | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used |

| Gateway D | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used |
| Gateway E | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used |
| Gateway F | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used | Can be used |
As can be seen from table 1, in the initial state, timeslots 1 to 10 under gateways a to F are all in the available state.
When the first terminal applies for the time slot of the gateway A, the gateway A reports to the server: a first terminal applies for a time slot of a gateway A, the first terminal is in a coverage range of a gateway B, the first terminal is associated with the gateway B, and a server: allocate the available slot 1 of gateway a to terminal 1, marking terminal 1 that slot 1 is not available on gateway B, as shown in table 2 below:
table 2:
and when other terminals apply for the time slot of the gateway B, the gateway B reports: the other terminals apply for the time slot on the gateway B, and the server allocates the available time slot of the gateway B to the other terminals (e.g. any one of the time slots 2-10).
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not intended to limit the embodiments of the present application.
After comparing the first time slot with each second time slot and obtaining the time slot comparison result, the target time slot which is in an available state under the target gateway and is different from the second time slot can be allocated to the first terminal.
According to the time slot allocation method provided by the embodiment of the application, a first heartbeat signal sent by a first terminal is received, the first heartbeat signal is sent by the first terminal when the first terminal is accessed to a first time slot of a target gateway, the first heartbeat signal comprises a second heartbeat signal of a second terminal monitored by the terminal, the first time slot and second time slots contained in the second heartbeat signals are subjected to time slot comparison, the second time slots are sent by the second terminal when the second terminal is accessed to the target gateway or a gateway adjacent to the target gateway, the target time slot of the target gateway is allocated to the first terminal according to a time slot comparison result, and the target time slot is a time slot different from the second time slot. The embodiment of the application can avoid the terminal in the cross area from being subjected to or carrying out channel interference, and carry out the binding of the mutual exclusion relation on the terminal equipment with a relatively short distance, thereby avoiding the channel interference.
Referring to fig. 3, a flowchart illustrating steps of another timeslot allocation method provided in this embodiment of the present application is shown, where the timeslot allocation method may be applied to a server, and specifically may include the following steps:
step 201: receiving a first heartbeat signal sent by a first terminal; the first heartbeat signal is sent by the first terminal when accessing a first time slot of a target gateway, and the first heartbeat signal comprises a second heartbeat signal of a second terminal monitored by the terminal.
The method and the device for allocating the time slot of the terminal access gateway can be applied to a scene of allocating the time slot of the terminal access gateway.
The server may be used to allocate time slots of the gateway to the terminals. There may be multiple gateways under a server, each gateway may have multiple time slots, and the server side may manage the status of each gateway under it.
The first terminal is a terminal for accessing a gateway under the server, in this embodiment, the first terminal may be a mobile terminal, such as a mobile phone, a tablet computer, and the like, and in this embodiment, the first terminal is preferably a hospital bed card.
The second terminal is a terminal which is adjacent to the first terminal and has the same access gateway as the gateway to which the first terminal is to access or has a cross coverage area with the gateway to which the first terminal is to access. In this embodiment, the second terminal may be a mobile terminal, such as a mobile phone, a tablet computer, and the like, and in this embodiment, the second terminal is preferably a hospital bed card.
The first heartbeat signal refers to a signal sent by the first terminal when the first terminal needs to access the first time slot of the target gateway.
The second heartbeat signal refers to a signal sent by the second terminal when the second terminal, which is monitored by the first terminal, accesses the target gateway or another gateway adjacent to the target gateway.
The first terminal will listen to the air signal in a heartbeat cycle when registering, and report to the uplink, which is divided into two cases: 1. when the first terminal registers with the target gateway for the first time, the first terminal can monitor and record the broadcast sent by the target gateway, so that the first heartbeat signal can be sent to the server. 2. When the first terminal is not registered with the target gateway for the first time, the first terminal may monitor and record a broadcast sent by the target gateway, and during this process, may also monitor heartbeat signals (i.e., second heartbeat signals) sent by other terminals.
If the terminal registered for the first time hears more than 1 gateway broadcast, the terminal is associated with the heard gateway and allocates a time slot, and if the time slot 1 is allocated, the associated gateway time slot 1 is in an unavailable state.
The terminal which is not registered for the first time releases the time slot of the gateway related to the terminal and becomes an available state. Firstly, determining whether a mutual exclusion device exists, if the gateway registered this time is the same as the gateway registered last time, and the heartbeat information sent by other terminals is monitored in the time slot in which the heartbeat is carried out last time, the mutual exclusion device exists, and if the mutual exclusion device exists, the allocated time slot needs to satisfy the mutual exclusion relationship (which is the second situation of the interference situation); if the gateway registered at the time and the gateway registered at the last time are not the same and represent that the terminal moves, contacting the mutually exclusive relationship between the terminal and other terminals; if multiple gateway broadcasts are also monitored, the corresponding time slot associated with the gateway becomes unavailable.
After receiving the first heartbeat signal transmitted by the first terminal, step 202 is executed.
Step 202: and under the condition that the first terminal is not accessed to the target gateway for the first time, acquiring and releasing the time slot of the first terminal which is accessed to the target gateway for the last time.
When the first terminal is a terminal which is not accessed to the target gateway for the first time, the time slot of the gateway related to the terminal is released and changed into an available state. For example, when the first terminal accesses the target gateway last time, the accessed time slot is time slot 2, and then when the first terminal accesses the target gateway again, the time slot 2 needs to be released.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not to be taken as the only limitation of the embodiments of the present application.
Step 203: comparing the first time slot with a second time slot contained in each second heartbeat signal; and the second time slot is sent when the second terminal accesses the target gateway or a gateway adjacent to the target gateway.
After receiving the first heartbeat signal sent by the first terminal, a time slot comparison may be performed between a first time slot included in the first heartbeat signal and a second time slot included in each second heartbeat signal, where the second time slot is a time slot sent by the second terminal when the second terminal is in an accessed target gateway or a gateway adjacent to the target gateway.
In this embodiment, the first time slot and the second time slot may be compared to determine whether the first time slot and the second time slot are the same.
After the time slot comparison between the first time slot and each second time slot, step 204 is performed.
Step 204: and when the first time slot is different from the second time slot, the first time slot is taken as a target time slot to be allocated to the first terminal, and the state of the target time slot is marked as an unavailable state.
When the first time slot and the second time slot are not the same, the first time slot may be allocated to the first terminal as a target time slot, and the state of the first time slot is marked as an unavailable state on the server side, that is, the first time slot under the target gateway is already occupied by the terminal.
Step 205: and when the first time slot is the same as at least one of the second time slots corresponding to the second terminals, acquiring target time slots different from the second time slots corresponding to the second terminals in the target gateway.
And when the first time slot is the same as at least one of the second time slots, acquiring a time slot different from the second time slot from the target gateway as a target time slot, and allocating the target time slot to the first terminal, for example, if the terminals 2, 3, and 4 are all allocated to the time slot 2, when the terminals are in heartbeat, the respective gateways may receive corresponding heartbeats, but may not receive the response of the gateways, the terminal 1 moves, and runs to the location 1' and the gateway C reports: the terminal 1 applies for a gateway C time slot; a server: allocating the available timeslot 1 of the gateway C to the terminal 1, and releasing the timeslot 1 of the gateway a and the gateway B associated with the terminal 1, as shown in the following table 3:
Table 3:
the terminal 2 moves and runs to the position 2', and the gateway C reports: terminal 2 applies for gateway C slot, server: allocating the available time slot 2 of the gateway C to the terminal 2, releasing the time slot of the gateway B occupied by the terminal 2, and releasing the mutual exclusion relationship between the terminals 2, 3, and 4, as shown in the following table 4:
table 4:
it should be understood that the above examples are merely illustrative for better understanding of the embodiments of the present application and are not to be construed as the only limitations on the embodiments of the present application.
After the target time slots with different second time slots corresponding to the second terminals in the target gateway are obtained when the first time slot is the same as at least one of the second time slots corresponding to the second terminals, step 206 is executed.
Step 206: and allocating the target time slot to the first terminal, and marking the state of the target time slot as an unavailable state.
After target time slots with different second time slots corresponding to the second terminals in the target gateway are obtained, the target time slots can be allocated to the first terminals, and the state of the target time slots is marked to be an unavailable state, namely the target time slots under the target gateway are occupied by the terminals. As shown in fig. 4, when the terminals 1 to N access the target gateway, the terminals 1 to N may be sequentially accessed, and after one terminal occupies one practice under the gateway, the state of the timeslot may be marked as unavailable, and the next terminal access may be performed.
Step 207: distributing the encryption and decryption keys corresponding to the target gateway to the first terminal; and the encryption and decryption key is used for encrypting and decrypting the interactive information between the first terminal and the target gateway.
In this embodiment, when the terminal registers with the gateway, the server may further allocate an encryption/decryption key of the gateway to the first terminal, where the encryption/decryption key may be used for performing encryption/decryption processing on the interactive information between the first terminal and the target gateway, so as to ensure the security of the interactive information.
