In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
Example one
The embodiment provides a system for enhancing the carrying capacity of a battery power supply bus type network system, which comprises a collector, a plurality of deconcentrators and a plurality of groups of slave devices; the collector is a host device powered by a battery; the deconcentrator is a program-controlled electronic switch; and a set of said slave devices comprises a plurality of slave devices; the collector is connected with a plurality of groups of slave devices through a bus, and a deconcentrator is arranged on the bus between each group of slave devices and the collector; the BUS is the M-BUS BUS or the RS-485 BUS.
The collecting device is used for outputting communication commands to control the on-off of the deconcentrators, so that only one deconcentrator is conducted, and only one group of slave equipment works; the communication command comprises an ID reading command, an ID writing command and a switch conduction command; the deconcentrator is used for responding to the communication command; the slave equipment and the deconcentrator are respectively provided with a unique identity ID code in a system unit governed by the acquisition device; the ID code is an electronic tag code for identification, and the ID codes of the slave equipment and the deconcentrator are designed into an ID array list.
When the system works, the collecting device is communicated with the calibration deconcentrator through the ID array table, so that a group of slave equipment works; the calibration deconcentrator is one of the plurality of deconcentrators.
Specifically, the identity ID code adopts a 14-bit compressed BCD code; and the number of the deconcentrators is at most 99; and the plurality of deconcentrators carry out asynchronous serial communication according to a certain communication protocol to realize data exchange.
Furthermore, the collector adopts a group of lithium ion batteries as a power supply.
In the specific implementation of the invention, an acquisition device, a plurality of sets of slave devices and a plurality of deconcentrators form each small system unit of a bus type network system, all instruments (slave devices) and deconcentrators in the whole small system unit are provided with unique electronic tag codes for identity identification, namely identity ID codes, in the small system controlled by the acquisition device, and the acquisition device controls asynchronous serial communication according to a certain communication protocol to realize data exchange; when a large system is composed of a plurality of collectors of small systems, each collector also sets an electronic tag code, namely an Identity (ID) code, which is unique in the large system and used for identity recognition. The communication protocol can adopt various current protocols or self-defined protocols according to a certain communication protocol, which does not affect the essential content of the invention, but at least needs to define a conduction command for controlling the switch of the deconcentrator additionally.
The physical connection mode of the system of this embodiment is: 1. the collecting device is connected with a plurality of deconcentrators through a bus. 2. Each deconcentrator is connected with a plurality of slave devices, and if n deconcentrators are connected below the collection device, for convenience of description, m deconcentrators are connected with m meters, and m is required to be more than or equal to 2, otherwise, the deconcentrator has no practical application significance.
The following description is about the program control flow of the process that the collector actively inspects the instruments hung below the collector and the central management host informs the collector to perform data interaction or control on a certain instrument:
firstly, the method comprises the following steps: the collector actively patrols the instruments (slave devices) hung below the collector:
1. in order to reduce the power consumption of the system and prolong the service life of the battery, the collector is controlled by a program to not supply power to an output bus of the collector when the data interaction between the collector and a subordinate instrument is not needed at ordinary times.
2. When the collecting device needs to inspect instruments under jurisdiction, the collecting device firstly supplies power to a BUS BUS output by the collecting device, at the moment, all deconcentrators connected together through the BUS are powered on and in a state of receiving collecting device commands, before the commands sent by the collecting device that an electronic switch of one deconcentrator is switched on are not received, electronic switches of all deconcentrators are in a disconnected state, the original switch state of the deconcentrators is in a disconnected state, and at the moment, all the instruments do not supply power.
3. The collector sends a switch closing command to the first splitter, and after the first splitter receives the switch closing command and confirms that the ID code of the splitter, which is sent by the collector and required to be closed, is consistent with the ID code of the collector, the first splitter controls the starting switch to be closed, and the BUS and BUS1 are communicated through the first splitter. In order to ensure that only one deconcentrator switch in the system is closed, other deconcentrators also receive a command which is sent by the collector and requires the first deconcentrator to be closed, the command is processed by a built-in program of the deconcentrator, if the command is inconsistent with the ID code of the deconcentrator, the deconcentrator controls the starting switch to be opened, namely, the deconcentrator starts one-time switch opening action as long as the switch closing command which is inconsistent with the ID code of the deconcentrator is found, and meanwhile, the switch opening command of the deconcentrator is not set in order to improve the working efficiency of the collector.
4. The concentrator sends commands requiring the meters to carry out data interaction in sequence according to the ID codes of the slave devices under the jurisdiction of the first configured splitter until the mth slave device, and at this time, all the splitters receive the commands but do not respond to the commands because the ID codes or the commands are not matched.
5. After the data interaction work of the mth slave device is completed, the collector sends a command for requiring the switch of the second wire divider to be closed again, at the moment, after other wire dividers including the first wire divider receive the command, the action of opening the switch is started, only the BUS2 is communicated with the BUS, and the collector repeats the action of the 4 th step.
6. And finishing the data interaction work of the collector on the instrument under the jurisdiction until the data interaction of the slave equipment connected below the nth deconcentrator is finished.
II, secondly, the method comprises the following steps: when the central management host informs the collector to perform data interaction on a certain instrument:
the process comprises the following steps: after receiving the command, the collector firstly positions the ID number of the deconcentrator with the instrument hung according to the ID code of the slave equipment and sets the ID number as IDx; then starting a bus to supply power and sending a command for starting connection of an IDx deconcentrator switch; and after the bus is stable, sending a data interaction command of the instrument, and after the data interaction is finished, directly cutting off the bus power supply by the collector.
The purpose of the invention is realized simply by adding the deconcentrator with the program-controlled electronic switch and the program-controlled steps, and the purpose of greatly improving the loading capacity of the collector is achieved.
Example two
As shown in fig. 1, in the topology structure diagram of the system for enhancing the loading capability of the battery-powered bus type network system: "I" is a battery-powered host device, i.e., a harvester; "II" is a program-controlled electronic switch, namely the deconcentrator; "III" is an intelligent bus-type slave device, i.e., an instrument (slave device). Suppose that n deconcentrators are hung under the collector, and the meters hung under each deconcentrator are the same in number, and all m meters are hung under each deconcentrator.
Assuming that the network system conforms to the 'CJ/T188-2004' communication protocol, wherein the ID codes of the deconcentrators and the meters adopt a unified 14-bit compressed BCD code, namely an address code of 7 bytes, the effective ID codes of the deconcentrators are 1 byte from 00000000000001 to 00000000000099, the deconcentrators hung below each collector are not repeated in number, and 99 deconcentrators are allowed to be hung at maximum; meanwhile, a special deconcentrator switch on command word is defined on the basis of meeting a CJ/T188-2004 communication protocol, the command word is defined as a No. 53 command, for a meter, the command is not responded, in the communication design, the deconcentrator only responds to 3 commands including an ID reading command, an ID writing command and a switch on command, and for other commands sent by the collection device, the deconcentrator does not respond, so that command conflict in the system can be avoided.
Assuming that n is 20 and m is 8, the total number of meters under the collecting device is 160, and the number of directly connected splitters is 20, for convenience of description, it is assumed that ID codes of the splitters and the meters are all arranged in sequence, and ID codes of the 20 splitters are 00000000000001 to 00000000000020, wherein 01-20 are valid IDs of the splitters; the ID codes of 160 meters are sequentially arranged from 19072800000001 to 19072800000160, every meter with 8 continuous ID codes is connected under a splitter, and a collector forms an ID storage array by combining 1-byte effective ID of the splitter and 7-byte meter ID, namely:
the 1 st deconcentrator is hung below: 0119072800000001- -0119072800000008
The 2 nd deconcentrator hangs down: 0219072800000009- -0219072800000016
.....................
The 20 th deconcentrator is hung below: 2019072800000153- -2019072800000160
When the collector needs to read the meter, the working process is as follows:
1. the collector supplies power to the bus output by the collector, all the deconcentrators are electrified and are in a communication monitoring state, and at the moment, all deconcentrator switches hung under the collector are in an off state in an initial state, namely all the instruments are not electrified.
2. The collector sends a switch conduction command of a first deconcentrator according to the highest position of the ID storage array, namely the ID code of the deconcentrator, and after receiving the command, the first deconcentrator responds to the ID code of the first deconcentrator by comparing the ID code with the ID code of the first deconcentrator, and then responds to the command to connect the electronic switch, so that the input BUS BUS1 of the 8 meters hung below the first deconcentrator is communicated with the output BUS BUS of the collector, and the 8 meters of 19072800000001 and 19072800000008 are supplied with power. If the remaining 19 dividers are compared and do not match their own ID numbers, the disconnection switch operation is performed, and even if the original switch is in the disconnected state, the disconnection switch operation is performed.
3. After the collector carries out proper time delay, the collector sequentially sends data reading commands of the 8 meters 19072800000001 and 19072800000008; at this time, the deconcentrator can receive the complete command, but the deconcentrator is in a communication receiving and listening state all the time because the command belongs to the command which the deconcentrator does not respond to.
4. After the data reading of 8 instruments hung under a first deconcentrator is finished, the collector sends a switch conduction command of a second deconcentrator, and after the command is received by the second deconcentrator, the command is compared to be consistent with an ID code of the collector, the command is responded, an electronic switch is communicated, an input BUS BUS2 of the 8 instruments hung under the second deconcentrator is communicated with an output BUS BUS of the collector, and the 8 instruments 19072800000009 plus 19080072000016 are supplied with power; and the rest 19 deconcentrators are compared and do not accord with the ID numbers of the deconcentrators, the disconnection switch operation is operated, including the first deconcentrator, so that the power supply of 8 meters, namely 19072800000001-.
5. After the collector carries out proper time delay, the collector sequentially sends out data reading commands of the 8 meters, namely 19072800000009 and 19072800000016.
6. The collector sends a switch conduction command to the 3 rd deconcentrator, and then sends a reading command of the meters hung below the collector in sequence, the data reading of the meters hung below the last deconcentrator is completed in sequence, and then the collector stops supplying power to the bus to complete the work task.
The meaning of the present invention is further explained by simple data operation in this embodiment:
suppose that: the current that every deconcentrator and the instrument of hitching in bus system consumed is I, and the hypothesis I is 1mA, and the quantity that articulates the instrument all is greater than 1 under every deconcentrator, because when being equal to 1, does not have practical meaning, supposes by 20 deconcentrators in the current little system that this collection ware constitutes, and every deconcentrator articulates 8 instruments, then has administered 160 instruments altogether:
by applying the technique of this invention: the current output by the collector is only: the current of 20 deconcentrators and the current of 8 meters hung under one deconcentrator, namely: (20+8) × I ═ 28 ═ 1mA ═ 28 mA.
Once this technique is not employed: the current that the collector needs to output is: the sum of the currents of all the meters it administers, i.e. 160 × I ═ 160 mA;
28mA/160mA 100% ═ 17.5%, i.e. with this invention the collector load current can be reduced significantly.
More to be noted are: the BUS power supply of most network systems is not 3.6V battery power supply voltage, such as an RS-485 system, generally a 7V to 15V system, and an M-BUS system generally a 22V to 40V system, a wired remote meter reading system in the market at present mainly adopts M-BUS BUS connection, when an acquisition device and a meter are connected by adopting an M-BUS, the M-BUS BUS voltage is assumed to be 22V, and the general voltage of a used battery is 3.6V, so that the voltage output to the BUS 22V needs to be boosted, and when the boosted energy conversion efficiency is not considered, the battery needs to output at least: 22/3.6 × 28mA 171.1mA, and 160 meters required 160mA, the battery required minimum output: 22/3.6 × 160mA 977.8mA, while the output capacity of the lithium ion battery of 34615 is typically below 250mA depending on the battery characteristics, so the practical significance of the present invention is quite high for battery-powered network systems.
From the above exemplary calculation data, the following conclusions were drawn: by the method of additionally installing the program control deconcentrator, the load capacity of the management slave equipment of the host equipment powered by the battery is greatly improved, and the service life of the battery is prolonged.
Compared with the prior art, the invention also has the following advantages:
