Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide a method, a device and a medium for acquiring the communication address of the electric meter, and the response time slots of the electric meters determined according to the residue result of the dispersion factors on the random numbers are different through different random numbers generated by the electric meter. Each ammeter sends response information with a communication address to the information acquisition terminal in the respective response time slot, and the information acquisition terminal can receive the response information with the communication address sent by the plurality of ammeters, so that the efficiency of acquiring the communication address of each ammeter is improved.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a flowchart of a method for acquiring a communication address of an electric meter according to an embodiment of the present invention, and as shown in fig. 1, the method for acquiring a communication address of an electric meter includes:
s10: and receiving a discrete table searching command sent by the information acquisition terminal.
S20: and judging whether effective communication is carried out with the information acquisition terminal.
If not, the process proceeds to step S30, and if so, the process proceeds to step S60.
S30: a random number is generated.
S40: and (4) according to a preset dispersion factor, the random number is subjected to remainder to determine a response time slot.
S50: and sending response information with a communication address to the information acquisition terminal in a response time slot.
S60: no response message is sent.
It should be noted that, the electric meter and the information acquisition terminal of the embodiment are both connected to the RS485 bus, and the execution main body of the embodiment is the electric meter. For step S10, the electric meter receives the discrete meter searching command sent by the information collecting terminal connected to the electric meter. The discrete meter searching command refers to a command for searching the communication address of the electric meter.
For the step S20, the electric meter determines whether effective communication is performed with the information collecting terminal, if the electric meter does not perform effective communication with the information collecting terminal, it indicates that the communication address of the electric meter is not registered in the information collecting terminal, and then the step S30 is performed; if the electricity meter is effectively communicated with the information acquisition terminal, the communication address of the electricity meter is registered in the information acquisition terminal, and the step S60 is proceeded. It is to be noted that effective communication means that both the electric meter and the information acquisition terminal successfully communicate, the acquisition terminal sends successful communication information to the electric meter after successful communication, and if the both parties fail to communicate, it is indicated that effective communication is not performed. The communication failure between the electricity meter and the information acquisition terminal is as follows, the information acquisition terminal sends a discrete meter searching command to the electricity meter connected with the information acquisition terminal, the electricity meter A and the electricity meter B send response information at the same time, the information acquisition terminal does not successfully receive the response information sent by the electricity meter A and the electricity meter B, and the communication process between the electricity meter A and the information acquisition terminal, namely, the invalid communication is carried out. The ammeter judges whether effective communication is carried out with the information acquisition terminal or not by judging whether successful communication information is received or not, if the ammeter receives the successful communication information, the ammeter indicates that effective communication is carried out with the information acquisition terminal, and if the ammeter does not receive the successful communication information, the ammeter indicates that effective communication is carried out with the non-information acquisition terminal. In step S40, it should be noted that the predetermined dispersion factor is a predetermined number, and the predetermined dispersion factor may be set by the information collecting terminal and placed in the discrete searching command to be sent to each electric meter, or may be preset in each electric meter. The dispersion factor in this embodiment is set by the information acquisition terminal and placed in the discrete meter searching command, and the numerical value of the dispersion factor is three times the number of the electric meters connected to the information acquisition terminal.
The random number is a number randomly generated by the electricity meter, the generation method of the random number is not limited, the specific generation method of the random number is determined by a code writer, and the generated random number can be determined by a Monte Carlo method.
It should be noted that the response gap is determined according to the remainder, where the response gap is the starting and ending time of sending the response information by the electric meter, the response gap is determined according to the remainder, the response information is sent by the electric meter in the second response time slot, and the starting time of the time slot is the time of the stop bit of the last byte of the discrete meter searching command sent by the information acquisition terminal.
The method for acquiring the communication address of the electric meter, which is provided by the invention, is applied to the electric meter and comprises the following steps: the method comprises the steps that an ammeter receives a discrete table searching command sent by an information acquisition terminal and then judges whether the ammeter is in effective communication with the information acquisition terminal or not, if the ammeter is in effective communication with the information acquisition terminal, the communication address of the ammeter is obtained by the information acquisition terminal, if the ammeter is not in effective communication with the information acquisition terminal, the communication address of the ammeter is not obtained by the information acquisition terminal, a random number needs to be generated, the random number is left according to a preset dispersion factor to determine a response time slot, and response information with the communication address is sent to the information acquisition terminal in different response time slots to enable the information acquisition terminal to obtain the communication address of the ammeter. All the electric meters connected with the information acquisition terminal can receive the discrete meter searching command, and the response time slots of the electric meters determined according to the random number surplus result of the dispersion factors are different through different random numbers generated by the electric meters. Each ammeter sends response information with a communication address to the information acquisition terminal in the respective response time slot, and the information acquisition terminal can receive the response information with the communication address sent by the plurality of ammeters, so that the efficiency of acquiring the communication address of each ammeter is improved.
On the basis of the previous embodiment, in another embodiment, the dispersion factor is specifically an integral multiple of the number of the electric meters connected to the information acquisition terminal, so that the same probability of the result of taking the remainder of the random numbers according to the preset dispersion factor is reduced, the response gaps of the electric meters are different as much as possible, and the possibility that the information acquisition terminal receives response information sent by a plurality of electric meters in the same response gap is reduced. The invention does not limit the dispersion factor to be several times of the number of the electric meters connected with the information acquisition terminal, and the specific times are determined according to the specification.
On the basis of the previous embodiment, in another embodiment, the response time slot is longer than the time for the ammeter to send the response information so as to ensure that the response information sent by the ammeter is received by the information acquisition terminal, and the response information is prevented from being lost or collided. The invention does not limit the value of the response time slot which is larger than the time of the ammeter sending the response information, and the specific value of the response time slot which is larger than the time of the ammeter sending the response information is determined according to the requirements of customers.

On the basis of the above detailed description of the method for obtaining the communication address of the electric meter, the present invention also discloses a method for obtaining the communication address of the electric meter, which is applied to the information acquisition terminal, and corresponds to the above method, as shown in fig. 2, the method includes:

For step S100, the information collecting terminal sends a discrete meter searching command to the electric meter through the communication bus to search for the communication address of the electric meter.
For step S200, the information collecting terminal receives the response information with the communication address sent by the electric meter in the response time slot through the communication bus to obtain the communication address of the electric meter. Since the embodiment of the processing portion of the discrete search command by the electric meter corresponds to the embodiment of the method for obtaining the communication address of the electric meter, applied to the electric meter, please refer to the description of the embodiment of the method for obtaining the communication address of the electric meter, applied to the electric meter, for the embodiment of the processing portion of the discrete search command by the electric meter, which is not repeated here.

All the electric meters connected with the information acquisition terminal can receive the discrete meter searching command, and the response time slots of the electric meters determined according to the random number surplus result of the dispersion factors are different through different random numbers generated by the electric meters. Each ammeter sends response information with a communication address to the information acquisition terminal in the respective response time slot, and the information acquisition terminal can receive the response information with the communication address sent by the plurality of ammeters, so that the efficiency of acquiring the communication address of each ammeter is improved.
On the basis of the previous embodiment, in another embodiment, the method further comprises the following steps:
after a communication address period of the electric meter is acquired, whether response information is received or not is judged;
if yes, sending the discrete table searching command again;
if not, the process is ended.
It should be noted that a period of obtaining the communication address of the electric meter refers to the time required for the information acquisition terminal to send the discrete meter searching command to receive the response information sent by the electric meter. One way to obtain the communication address period of the meter is to multiply the dispersion factor by the response time slot.
In the specific implementation, after a period of obtaining the communication address of the electric meter, whether the information acquisition terminal receives the response information is judged, if so, the information acquisition terminal indicates that part of the communication addresses of the electric meter are not recorded in the information acquisition terminal in the meter searching process, and in order to comprehensively record all the communication addresses of the electric meters connected with the information acquisition terminal, a discrete meter searching command needs to be sent again to obtain the communication addresses of the electric meters which are possibly not recorded in the information acquisition terminal; if the response information is not received, the communication addresses of the electric meters in the electric meter searching process are all recorded in the information acquisition terminal, and the searching is finished.
According to the embodiment, whether the next period of acquiring the communication address of the ammeter is determined according to whether the information acquisition terminal receives the response information after one period of acquiring the communication address of the ammeter, the period is more intelligent, and the workload of workers is reduced.

if not, the response information sent by the electric meter is reserved.
In the specific implementation, the electric meters determine the response time slots by taking the balance of the random numbers according to the preset dispersion factors, and the random numbers are not fixed, so that the response time slots of the electric meters are possibly the same, and if the information acquisition terminal receives the response information sent by the electric meters in the same time slot, the response information sent by the electric meters is discarded, and abnormal information is generated.
In order to avoid the received communication address of the electric meter from being abnormal, the information acquisition terminal of the embodiment adopts a discarding strategy for a plurality of pieces of response information received in the same time slot, so that the accuracy of obtaining the communication address of the electric meter is guaranteed.
