In current intelligent express delivery cabinet, when carrying out the communication between main base and a plurality of sub-base or a plurality of cabinets body, the data issue can appear in the inevitable and report the conflict and lead to the unusual condition of intelligent express delivery cabinet, when this problem appears, if can not in time correct, lead to the stability of intelligent express delivery cabinet system to descend easily.
Therefore, the problem actually solved by the present invention is how to avoid data communication conflicts between the main chassis and the sub chassis.
As an example of the present invention, as shown in fig. 1, a frame structure of an intelligent express cabinet system of the present invention and as shown in fig. 2, a communication frame structure between a main base and a sub base in the intelligent express cabinet system of the present invention are provided, where the intelligent express cabinet system includes the main base and a plurality of sub bases, and each of the main base and the plurality of sub bases has an independent control unit, that is, the main base and the sub bases can be used by independent control terminals on left and right sides, and can receive/send commands or receive/report data, and a communication protocol is performed between the main base and the plurality of sub bases through an RS485 bus.
In this embodiment, as shown in fig. 3, the data collision prevention method includes:
s1, presetting a communication unit cycle, wherein the time axis of the communication unit cycle is divided into a sending time period and a reporting time period, the reporting time period is divided into a plurality of time slots, and each time slot corresponds to one sub-base to report data;
in order to ensure that only one data is transmitted at the same time in a communication link between the main base and the auxiliary base, a time-sharing processing mechanism is adopted, namely, the reporting time and the issuing time of the data are separated.
Specifically, the preset communication unit period is generally preloaded in the timer in advance, even if the time axis of the communication unit period in the timers in the main base and the sub base divides the issuing time period and the reporting time period, if the reporting time period is divided into a plurality of time slots, each time slot corresponds to one sub base to report data.
According to the above, for example, taking a communication unit cycle of 1s as an example, the first 0ms to 800ms is a time period for issuing a command/data from the main base to the sub-base, and 800ms to 1000ms is a time period for reporting data from the sub-base to the cabinet body; in addition, generally, the number of the sub-chassis is multiple, and in order to avoid the sub-chassis reporting data, only one data transmission is in a link between the main chassis and the sub-chassis, the multiple sub-chassis are hierarchically corresponding to multiple time slots, for example, as shown in fig. 1, a time period of 800ms to 850ms is a time period for the sub-chassis (1) to report data, a time period of 850ms to 900m is a time period for the sub-chassis (2) to report data, a time period of 900ms to 950ms is a time period for the sub-chassis (3) to report data, and a time period of 950ms to 1000ms is a time period for the sub-chassis (4) to report data.
S21, judging whether the time counted by the timer in the main base is within the issuing time period, if so, issuing a control command to the auxiliary base by the main base;
in this embodiment, the step of determining whether the time counted by the timer in the main base is within the delivery time period is mainly performed by the control unit of the main base, the control unit of the main base constantly monitors the time counted by the timer in the main base, and the control unit of the main base determines whether the time counted by the timer in the main base is within the delivery time period, for example, within 0ms to 800ms, if so, the main base delivers the control command to the sub-base, and if not, the main base delivers the control command to the sub-base after waiting for the time counted by the timer in the main base to be within 0ms to 800 ms.
And S22, judging whether the time counted by the timer in the sub-base is within the reporting time period, if so, reporting the data to the main base by the plurality of sub-bases in sequence.
According to the above, when the time for the main base to wait for the timer in the main base to count is within 800ms to 1000ms, the main base considers that the data is reported in the sub-base.
Ideally, the timer in the primary base counts up to a time that is consistent with the time counted by the timer in the secondary base.
In this embodiment, the step of determining whether the time counted by the timer in the sub-base is within the delivery time period is mainly performed by the control unit of the sub-base itself, the control unit of the sub-base constantly monitors the time counted by the timer in the main sub-base, the control unit of the sub-base determines whether the time counted by the timer in the sub-base is within the delivery time period, for example, within 0ms to 800ms, if so, the sub-base reports data to the main base, if not, the sub-base reports data to the main base after waiting for the time counted by the timer in the sub-base to be within 800ms to 1000ms, each sub-base reports data corresponding to a different time slot, and when the time counted by the timer in the sub-base to be within the sub-base is within a preset time slot, the sub-base reports data to the main base.
As shown in fig. 3, in an exemplary embodiment, when the main base issues a control command to the sub base, the timer of the main base and the counter cooperating with the timer of the main base are cleared, and the timers of the main base and the sub base are clocked.
When the main base issues a control command to the auxiliary base, the main base issues a command for switching on a timer of the main base and a zero clearing end of a counter, even if the counting frequency of the counter of the main base is 0, the counting time of the timer is 0ms, and the main base issues a clock synchronization command.
According to the above, all the bases are connected in parallel through the RS485 bus between the main base and the auxiliary base, and the main base can receive all the auxiliary bases and clear the timer and the counter, so that the clock synchronization of the communication link between the main base and the auxiliary base is realized, and the data collision is avoided during data communication between the main base and the auxiliary base.
As shown in fig. 4, in an exemplary embodiment, when a plurality of sub-bases report data to a main base in sequence, after a first sub-base reporting data to the main base completes reporting, the sub-base triggers a clock synchronization command, and the clock synchronization command indicates that all sub-bases perform clock synchronization.
When the sub-bases do not transmit data and work for a long time, the counts of the timers of the sub-bases are generally inconsistent, when a plurality of sub-bases report data to the main base in sequence, after the first sub-base reporting the data to the main base finishes reporting, the sub-base triggers a clock synchronization command, for example, the first sub-base reporting the data to the main base reports in a preset time slot of 800 ms-850 ms, and when the sub-base finishes reporting at the time of 800ms, the sub-base triggers a clock synchronization command, so that the counts of the timers of the remaining sub-bases are synchronized to 800ms, and collision of the reported data of the remaining sub-bases are avoided.
As another example of the present invention, as shown in fig. 1, a frame structure of an intelligent express cabinet system of the present invention and as shown in fig. 2, a communication frame structure between a main base and a sub base in the intelligent express cabinet system of the present invention are provided, the intelligent express cabinet system includes a main base, a plurality of sub bases and a plurality of cabinets, each of the main base, the plurality of sub bases and the plurality of cabinets has an independent control unit, that is, the main base, the sub bases and the cabinets can be used by independent control terminals on the left and right, and can receive/transmit commands or receive/report data, a communication protocol is performed between the main base and the plurality of sub bases through an RS485 bus, the sub bases and the cabinets connected to the sub base column perform a communication protocol through an RS485 bus, in this embodiment, the sub bases are connected to the main base through the RS485 bus in a parallel manner, the commands/data transmitted by the main base, all the auxiliary bases can be received, and the communication mode between the main base and the auxiliary bases and the communication mode between the auxiliary bases and the cabinet body are not interfered with each other.
In this embodiment, as shown in fig. 5, the data collision prevention method includes:
s1': presetting a communication unit cycle, wherein the time axis of the communication unit cycle is divided into a downlink time period and a reporting time period, the reporting time period is divided into a plurality of time slots, and each time slot corresponds to one auxiliary base or cabinet body to report data;
s21': judging whether the time counted by a timer in the main base is within the issuing time period or not, if so, issuing a control command to the auxiliary base by the main base;
s22': judging whether the time counted by a timer in the auxiliary bases is within a reporting time period, if so, reporting data to the main base by the plurality of auxiliary bases at one time;
s23': and judging whether the time counted by the timer in the cabinet body is within the reporting time period, if so, reporting the data to the auxiliary base by the plurality of cabinet bodies in sequence.
According to the above embodiments, a method for preventing data collision when data communication is performed between the main chassis and the sub chassis has been described, which is not necessarily stated herein.
In step S23', it is determined whether the time counted by the timer in the sub-chassis is within the reporting time period, and if so, the sub-chassis reports data to the main chassis at a time.
According to the above, when the time counted by the timer in the sub-base waiting for the sub-base is within 800ms to 1000ms, the sub-base considers that data is reported in the cabinet body on the sub-base row.
Ideally, the timer in the sub-base counts the same time as the timer in the cabinet body.
In this embodiment, whether the time counted by the timer in the sub-base is within the reporting time period is judged, mainly by a control unit of the cabinet body on the sub-base column, the control unit of the cabinet body constantly monitors the time counted by the timer in the main cabinet body, the control unit of the cabinet body judges whether the time is within the sending time period, for example, within 0ms to 800ms, if so, the sub-base sends a control command to the cabinet body of the sub-base column, if not, the sub-base reports data to the sub-base after the time counted by the timer in the sub-base is within 800ms to 1000ms, each cabinet body reports data corresponding to a different time slot, and when the time counted by the timer in the cabinet body is within a preset time slot, the sub-base reports data.
As shown in fig. 6, in an exemplary embodiment, when the sub-chassis does not need to report data to the main chassis, a clock synchronization command is sent by the sub-chassis to the plurality of cabinets of the sub-chassis column, the clock synchronization command instructing clocks to be synchronized for the counter counts in the cabinets of the sub-chassis column to return to zero.
Because the sub-base is connected with the cabinet bodies of the sub-base row in a parallel connection mode through the RS485 bus during communication, the sub-base only needs to send a command to enable all the cabinet bodies of the sub-base row to receive the command once, if the command is the command for resetting the counter and the timer, namely the counter in all the cabinet bodies counts for 0, the timer in all the cabinet bodies counts for 0ms, and the clock synchronization of the whole intelligent express cabinet system is realized by combining the reset steps of the timer and the counter in the main base and the sub-base.
As shown in fig. 7, in an exemplary embodiment, when a plurality of cabinets report data to the main base in sequence, after the first cabinet reporting data to the sub-base completes reporting, the first cabinet triggers a clock synchronization command, where the clock synchronization command indicates that the cabinets on the sub-base row perform clock synchronization.
When the cabinets do not perform data transmission and work for a long time, the situation that the counts of the timers of the cabinets in each sub-base row are inconsistent generally exists, when a plurality of cabinets report data to the main base in sequence, the first cabinet reporting data to the sub-base triggers a clock synchronization command after the report is completed, for example, the first cabinet reporting data to the sub-base reports in a preset time slot interval of 800ms to 850ms, and when the cabinet finishes the report at the time of 800ms, the clock synchronization command is triggered once, so that the count clocks of the timers of the rest cabinets are synchronized to 800ms, and collision and conflict of the rest cabinets in reporting data are avoided.
In addition, when data is received and sent between the main base and the auxiliary base and between the auxiliary base and the cabinet body arranged in the auxiliary base row, due to the fact that the time of the timer of the auxiliary base is inconsistent with the time of the timer of the cabinet body, the sending is abnormal, for example, when the main base sends a control command and needs to acquire data from the cabinet body through the auxiliary base, the data uploaded by the cabinet body is prone to being detained in the auxiliary base, and therefore more than one piece of data is transmitted between the main base and the auxiliary base, and data collision is disordered, and the setting is carried out, when the counter of the main base finishes 1 counting, the main base can send a clock synchronization command downwards, and the whole intelligent express cabinet system achieves one-time clock synchronization.
Furthermore, when the intelligent express delivery cabinet system is not used for a long time, that is, the express delivery cabinet may not have any operation within a period of time, for example, in a state where the express delivery cabinet is not operated by a person at night, the situation that the counting time of the timers of the main base, the sub base and the cabinet body is not synchronous easily occurs within the period of time, therefore, the main base sends a clock synchronization command once every preset time, for example, the preset time is set to be 30min or 1h, so that the whole intelligent express delivery cabinet system realizes clock synchronization once.
In an exemplary embodiment, as shown in fig. 8, an intelligent courier cabinet system is provided, comprising
The timing communication module 10 is used for presetting a communication unit cycle, dividing a time axis of the communication unit cycle into a sending time period and a reporting time period, wherein the reporting time period is divided into a plurality of time slots, and each time slot corresponds to one auxiliary base or cabinet body to report data;

and the third judging module 40 is configured to judge whether the time counted by the timer in the cabinet is within the reporting time period, and if so, the plurality of cabinets report data to the sub-base in sequence.
In an exemplary embodiment, the intelligent express delivery cabinet system further includes:
the first clock synchronization module 21 is configured to trigger a clock synchronization command once after a first cabinet reporting data to the secondary base finishes reporting when the plurality of cabinets report data to the primary base in sequence, where the clock synchronization command indicates that clock synchronization is performed on the cabinets in the secondary base row;
the second clock synchronization module 31 is configured to, when the plurality of cabinets sequentially report data to the main base, trigger a clock synchronization command once by the first cabinet reporting data to the sub-base after the report is completed, where the clock synchronization command indicates that clock synchronization is performed on the cabinets in the sub-base row.
Further, intelligence express delivery cabinet system still includes:
and a third clock synchronization module 41, configured to send, by the sub-base, a clock synchronization command to the plurality of cabinets in the sub-base row when the sub-base does not need to report data to the main base, where the clock synchronization command indicates that the counter in the cabinets in the sub-base row returns to zero to synchronize clocks.

the system comprises at least one processor (processor), a communication Interface (communication Interface), at least one memory (memory) and a communication bus, wherein the at least one processor, the communication Interface and the at least one memory are communicated with each other through the communication bus.
