It includes electric machine valve driving circuit, count interface circuit, power supply, FLASH reservoirs, liquid crystal display, buzzer, button, CPU controls
Device (master controller) processed and communication module composition, wherein electric machine valve driving circuit, counting interface circuit, power supply, FLASH are deposited
Reservoir, liquid crystal display, buzzer, button and communication module are connect with cpu controller (master controller).
It is communicated it should also be noted that, the communication module in the present embodiment can be gsm communication or GPRS, or be
Therefore various modes may be used when gas meter, flow meter carries out networking in 485 communications or ZigBee communication：It may be used in data set
Device carries out the data relay between gas meter, flow meter and computer system, can also use each gas meter, flow meter directly by GSM and/or
GPRS carries out data interaction with computer system.Specifically, the communication interface of communication module can be wired using 485 in gas meter, flow meter
Communication can also use the short-distance wireless communications such as ZigBee, to make more gas meter, flow meters in a building or a cell
It is connected on a data concentrator, then data concentrator reuses GSM and/or GPRS is connected with internet, realizes long-range
Communication；Communication interface alternatively, it is also possible to make the communication module of each gas meter, flow meter is all GSM and/or GPRS, without using number
According to concentrator, every table can independently realize remote control.
Embodiment 2
As shown in Fig. 2, the present embodiment provides a kind of Internet of Things gas meter, flow meter that can independently upgrade that embodiment 1 is provided into
The upgrade method of row upgrading, gas meter, flow meter are applied to master controller after the power is turned on, including：
Step S1：Run the code in updated boot programs code storage area；
Step S2：Upgraded according to the code guiding gas table in updated boot programs code storage area or gas meter, flow meter is made to run
The code stored in normal work program code storage area.
Specifically, described in step S2 according in updated boot programs code storage area code guiding gas table upgrading or
The code stored in gas meter, flow meter normal operation working procedure code storage area is set to specifically include：
Check in Flash reservoirs whether there is gas meter, flow meter upgrade code, if nothing, normal operation working procedure code storage area
Otherwise the code of middle storage carries out in next step；
Gas meter, flow meter upgrade code in Flash reservoirs is burnt to normal work program code storage area and by Flash
Gas meter, flow meter upgrade code erasing in reservoir；
The gas meter, flow meter upgrade code of new burning, normal operation after the completion of upgrading in normal operation working procedure code storage area
Code when the new gas meter, flow meter normal work stored in working procedure code storage area.
What needs to be explained here is that in gas meter, flow meter electrifying startup, updated boot programs code storage area can all be gone to read
Instruct and run corresponding program, in program operation process, user can taking human as change or setting master controller in PC pointers,
PC pointers are made to redirect the code stored in normal operation working procedure code storage area.In addition, after gas meter, flow meter electrifying startup,
Updated boot programs code executes at the first time, and updated boot programs code mainly realizes following functions：Check Flash reservoirs
In whether have upgrade code, if so, upgrade code and being burned onto the normal work in main control area from being read in Flash reservoirs
Make program code storage area, after the completion of burning, the upgrade code in Flash reservoirs is wiped, if not provided, making master controller
PC pointers jump to the start address of code in normal work program code storage area.
It should also be noted that, after upgrade code is stored into normal work program code storage area, journey is worked normally
The code that original normal work is run in sequence code storage area is just capped, and is run after the completion of gas meter, flow meter upgrading new
Operation code can.
Preferably, further including in the gas meter, flow meter escalation process or in normal course of operation：
Step P1：Upgrade code is received by communication module；
Step P2：Upgrade code is stored into Flash reservoirs；
Step P3：Gas meter, flow meter, which automatically resets, restarts, and then carries out step S1, that is, carries out the reading updated boot programs generation
Code storage area in code the step for.
What needs to be explained here is that in order to make gas meter, flow meter keep last state at any time, once there is upgrading in Flash reservoirs
Code, gas meter, flow meter are upgraded by the upgrade code in Flash reservoirs at once, even if in gas meter, flow meter course of normal operation,
Once gas meter, flow meter receives the upgrade code that computer server or concentrator issue, gas meter, flow meter is defaulted as storing up by upgrade code
It is stored to after Flash reservoirs and carries out restarting upgrading at once, certainly, gas meter, flow meter upgrading can be arranged when specifically used in user
Trigger condition, the update time and upgrade mode to make gas meter, flow meter are more flexible, such as when gas meter, flow meter receives upgrade command
When, gas meter, flow meter is not upgraded at once, it is necessary to just be upgraded after being confirmed by user, or be referred to when gas meter, flow meter receives upgrading
It needs to be upgraded in special time period after order, avoids the normal use for influencing gas meter, flow meter.
Preferably, the step P1, i.e., further include before receiving upgrade code by communication module：Step P0：Pass through
Communication module receives upgrade command.
Preferably, the step P1, i.e., further include before receiving upgrade code by communication module：
Step P01：Upgrade command is received by communication module；
Step P02：Judge whether the upgrade command is legal, (is received and risen by communication module if so, carrying out step P1
The step for grade code), otherwise, generation when continuing ongoing upgrade step originally or continuing to run with gas meter, flow meter normal work
Code.
It should also be noted that, when gas meter, flow meter is communicated by concentrator with remote computer, gas meter, flow meter is being carried out
When upgrading, upgrade code is issued in concentrator by computer system first, and concentrator sends upgrade code to gas meter, flow meter again, or
Person's concentrator first sends upgrade command to gas meter, flow meter, and in order to reinforce Information Security, gas meter, flow meter can be first to the conjunction of upgrade command
Method is judged, if it is decided that is legal, then receive the upgrade code that concentrator issues by communication module.In addition, combustion gas
Table can also directly receive the upgrade command and/or upgrade code that remote computer issues.
In the present embodiment, described upgrade code is stored into Flash reservoirs (step P2) can also specifically include：Sentence
Whether the upgrade code that disconnected communication module receives updates, no if update, upgrade code is stored into Flash reservoirs
Then, code when continuing ongoing upgrade step or continuing to run with gas meter, flow meter normal work.What needs to be explained here is that having
When the upgrade code that receives of communication module as the upgrade code that last time receives, in order to avoid flogging a dead horse, this implementation
The process of such a judgement can be increased in example.
It is described to be specially by communication module reception upgrade code (step P1) in the present embodiment：By communicating mould
Block receives the upgrade code that external host computer or external concentrator issue.
It the above is only the preferred embodiment of the present invention, it is noted that above-mentioned preferred embodiment is not construed as pair
The limitation of the present invention, protection scope of the present invention should be subject to claim limited range.For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, several improvements and modifications can also be made, these change
Protection scope of the present invention is also should be regarded as into retouching.
