Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described by means of implementation examples with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The low-voltage centralized meter reading system mainly utilizes an information acquisition system to realize unified planning, unified coordination and unified control of each link of meter reading, thereby achieving the purpose of remote automatic meter reading. The intelligent electric energy meter comprises a main station device, an electric energy meter and a concentrator connected with the main station device and the electric energy meter, or further comprises a collector arranged between the concentrator and the electric energy meter.
Example 1
Fig. 1 is a flowchart of a clock timing method of a low-voltage meter centralized meter according to an embodiment of the invention. The technical scheme of the embodiment is suitable for the situation of classifying clock pairs of the low-voltage meter reading electric energy meter. The method can be executed by the low-voltage meter reading clock time setting device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware mode and is configured to be applied in a main equipment processor. The method specifically comprises the following steps:
s101, sending a calling command to a corresponding slave device according to a calibration signal, receiving feedback information returned by the slave device based on the calling command, and determining the time to be calibrated of the corresponding slave device according to the sending time of the calling command, the time carried by the feedback information and the receiving time of the feedback information, wherein the slave device is directly controlled by a master device or is directly and indirectly controlled by the master device, and the calibration signal is generated based on the feedback information when the master device is a non-master device.
Wherein the master device is not a member of the same class as the slave device. Specifically, when the master device is a master device, the slave device is a concentrator; when the concentrator is the main equipment, the auxiliary equipment is a collector corresponding to the concentrator; when the collector is the main equipment, the auxiliary equipment is an electric energy meter corresponding to the collector; or when the master device is a master device, the slave device is a concentrator; when the concentrator is the main equipment, the auxiliary equipment is the collector corresponding to the concentrator and the electric energy meter corresponding to the collector.
The calibration signal is used for triggering the master device to send a calling command to the corresponding slave device. When the master equipment is master equipment, a calibration signal is generated based on a set time, for example, a calibration signal is automatically generated in a 1:45 time sharing mode, and the master equipment sends a calling command to the concentrator based on the calibration signal; a further calibration signal is automatically generated at time 2:45, based on which the master station device sends a recall command to the concentrator, and so on, the calibration signal is automatically generated at 45 minutes per hour. When the master device is a non-master device, its calibration signal is generated based on feedback information it transmits, e.g. the calibration signal is generated at the same time as the feedback information is generated, or the calibration signal is generated when the feedback information is sent out. Therefore, the calling command sending time of the back-end equipment of the low-voltage centralized meter reading system is earlier than that of the front-end equipment, and the setting can improve the accuracy of the clock of the non-master equipment serving as the master equipment, so that the time setting accuracy of the whole system is improved.
In one embodiment, the sum of the average value of the difference between the receiving time of the feedback information and the sending time of the recall command and the time carried by the feedback information is taken as the time to be calibrated of the slave device, wherein the time carried by the feedback information is the time when the recall command is received by the slave device. The time to be calibrated is used to represent the time of the slave device when the master device receives feedback information. For example, the time for the master device to send the recall command is 4:50, the time for carrying the feedback information is 4:51, and the time for receiving the feedback information is 4:53, so when the master device receives the feedback information, the time to be calibrated of the slave device is 4 points 52 minutes 30 seconds. It can be understood that the average value of the difference between the receiving time of the feedback information and the sending time of the recall command is used for compensating the time period from when the slave device sends the feedback information to when the corresponding master device receives the feedback information, and the time when the slave device sends the feedback information plus the time period is the time when the master device receives the corresponding feedback information.
In one embodiment, one master device corresponds to at least two slave devices, and the feedback information carries the identification information of the slave devices while carrying the time information. In an exemplary embodiment, one concentrator corresponds to a plurality of collectors, and at this time, feedback information sent to the concentrator by any collector carries time information and also carries self-identification, so that the concentrator distinguishes feedback information of different collectors.
In order to reduce the invalid time and the influence of time on meter reading of the ammeter, the sending time of the calling command is set at the collection idle time and avoids the number 1 of each month, such as the last 15 minutes of each hour.
S102, determining a clock deviation value of time to be calibrated by taking the body clock as a reference, and performing time setting operation on the slave device when an average deviation value corresponding to the clock deviation value meets a preset calibration condition.
The preset calibration conditions comprise an error level corresponding to the average deviation value and a time synchronization period corresponding to the error level. The setting of the preset standard conditions can realize different time setting operations according to the time deviation of the slave equipment, so that time setting times are effectively reduced, and time setting accuracy is improved.
In one embodiment, if the average deviation value corresponding to the clock deviation value in the preset number or the preset time is smaller than the first set time threshold and accords with the first calibration period, performing time synchronization operation on the slave device; if the average deviation value corresponding to the clock deviation value in the preset quantity or the preset time is larger than the first set time threshold value and smaller than the second set time threshold value and accords with the second calibration period, the slave device is subjected to time setting operation; the first set time threshold is less than the second set time threshold, and the first calibration period is greater than the second calibration period.
Taking a master device as a concentrator and an ammeter as a slave device as an example. The clock bias value of the ammeter is the concentrator time minus the time to be calibrated. When the clock deviation value of the ammeter is larger than 5 minutes (the first set time threshold value) and smaller than 8 minutes (the second set time threshold value), the clock deviation value is marked as the clock deviation value of the ammeter, the clock deviation value of the ammeter is recorded for time comparison times, the clock deviation value of the ammeter is updated, the average deviation value corresponding to the clock deviation value of the preset quantity at the current moment is calculated, or the average deviation value corresponding to the clock deviation value in the preset time at the current moment is calculated. When the clock deviation value of the ammeter is greater than 8 minutes (second set time threshold), marking as serious deviation of the clock of the ammeter, recording the time comparison times, updating the serious deviation times of the clock of the ammeter, and calculating the average deviation value corresponding to the clock deviation value of the preset quantity at the current moment or the average deviation value corresponding to the clock deviation value in the preset time at the current moment. When the clock deviation value of the ammeter is smaller than or equal to 5 minutes (a first set time threshold), marking that the clock of the ammeter is normal, recording the time comparison times, updating the normal times of the clock of the ammeter, and calculating the average deviation value corresponding to the clock deviation value of the preset quantity at the current moment or the average deviation value corresponding to the clock deviation value in the preset time at the current moment. And when no effective feedback information is received, generating an abnormal identifier and updating the abnormal times. If the average deviation value is greater than 5 minutes (first set time threshold) and less than 8 minutes (second set time threshold) while satisfying 24 hours that the time setting operation is not performed, the time setting operation is performed on the electricity meter. And when the average deviation value is smaller than 5 minutes (a first set time threshold value) and the term is satisfied that the time setting operation is not performed, performing the time setting operation on the electric energy meter. If the average deviation value is larger than R (second set time threshold), the time setting operation is not executed on the electric energy meter, an electric energy meter clock out-of-tolerance event is generated, and the master station is reported. In this embodiment, the slave device having a large average deviation value level has a larger time setting frequency than the slave device having a small average deviation value level, and the setting can reduce the time setting times without affecting the use of the device. Wherein the average deviation value level corresponds to a set time threshold. For example, the average deviation value a is greater than the first set time threshold and less than the second set time threshold, and the average deviation value B is less than the first set time threshold, then the level of the average deviation value a is greater than the level of the average deviation value B.
In one embodiment, when the average deviation value is greater than the first set time threshold, the time alignment magnitude of the time alignment operation is less than or equal to a set alignment time interval, such as the first set time threshold, such that the clock time of the slave device gradually approximates the clock time of the corresponding master device. This embodiment helps to improve the accuracy of the time setting operation.
Compared with the prior art of unified time setting of the master station equipment, the technical scheme of the clock time setting method for the low-voltage centralized meter reading electric energy meter, provided by the embodiment of the invention, has the advantages that when the master equipment is non-master station equipment, a calibration signal is generated based on feedback information, and time setting operation of corresponding slave equipment is started according to the calibration signal, so that the purpose of classifying time setting according to set time sequences is realized, and the flexibility and timeliness of time setting operation of a low-voltage centralized meter reading system are improved.
