Embodiment
Below in conjunction with accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.The assembly of the utility model embodiment describing and illustrate in usual accompanying drawing herein can be arranged with various different configuration and design.Therefore, below to the detailed description of the embodiment of the present utility model provided in the accompanying drawings and the claimed scope of the present utility model of not intended to be limiting, but selected embodiment of the present utility model is only represented.Based on embodiment of the present utility model, the every other embodiment that those skilled in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
The utility model example 1 provides the acquisition module for remote meter reading, as shown in Figures 2 and 3, comprise: mechanical character wheel 110, the magnet steel 111 that described mechanical character wheel 110 is arranged and the sampling plate matched with magnet steel 111, described sampling plate is Hall element; Described magnet steel 111 can rotate with the rotation of described mechanical character wheel 110, and when described magnet steel 111 rotates to assigned address, described sampling plate produces sampled signal.
Mechanical character wheel 110 is on water meter, gas meter, and along with the use amount of water or rock gas increases and the device of the rotating disk dress of rotation, its number of turns of rotating is more, illustrates that the consumed resource that water meter or gas meter record is larger.In correlation technique, also just by drawing in certain hour to the confirmation of mechanical character wheel 110 rotating cycle the quantity using water or rock gas.What namely measure water or gas consumption is primarily the rotating cycle that will identify mechanical character wheel 110.Mechanical character wheel 110 also has multiple, same table is also exist simultaneously multiple, the character wheel of the hour hands of its function and quartz watch, minute hand, second hand is similar, is played the effect of record by the multiple character wheels (character wheel of the different numerical digit of height) be connected.Usually, magnet steel 111 to be arranged on the mechanical character wheel 110 of lowest-order digit (mechanical character wheel 110 as 1/1000 numerical digit or 1/100 numerical digit), to make the data recorded more accurate.
Concrete, Hall element is made up of semiconductor material, it has extremely strong susceptibility to magnetic field, therefore when the relative position of the magnetic field that magnet steel 111 sends and sampling plate changes time, sampling plate can according to the power in magnetic field (one end as magnet steel 111 faces/perpendicular to sampling plate time, magnetic field intensity received by sampling plate be maximum), when magnetic field intensity exceedes predetermined numerical value produce sampled signal.Magnet steel 111 rotates along with the rotation of mechanical character wheel 110, thus the magnetic field driving magnet steel 111 to send is also in rotation, when the magnetic field intensity that sampling plate detects is excessive, then produce sampled signal, by the metering to sampled signal quantity in subsequent conditioning circuit, just can know the number of turns that magnet steel 111 rotates, also just can know the rotating cycle of mechanical character wheel 110.And then pass through the specification of the mechanical character wheel 110 recognized in advance, thus the use amount of conversion water outlet/rock gas.
Further, in order to confirm that the sampled signal that sampling plate obtains is accurately, two or more sampling plate can be used to be separately positioned on the vicinity (the two ends place as mechanical character wheel 110 radial direction) of mechanical character wheel 110.Below to use two sampling plates to be described, namely, described sampling plate comprises the first sampling plate 112 and the second sampling plate 113, and it is the both sides of mechanical character wheel 110 that described first sampling plate 112 and described second sampling plate 113 are separately positioned on.
The magnetic field rotating that first sampling plate 112 and the second sampling plate 113 all can produce at magnet steel 111 produces corresponding sampled signal in certain position.As the first collection plate and the second collection plate being listed in respectively the both sides of mechanical character wheel 110, then can ensure that the every half revolution of character wheel can make the first sampling plate 112 or the second sampling plate 113 produce sampled signal, thus by gathering the signal on the first sampling plate 112 and the second sampling plate 113, confirm the number of turns that mechanical character wheel 110 rotates.Certainly, the quantity of sampling plate can not be two, goes back three, four, or more, and multiple sampling plate can arrange along the edge of mechanical character wheel 110, and the distance that interval is identical.After each sampling plate all produces sampled signal, just can think that mechanical character wheel 110 have rotated one week.If certain sampling plate does not send sampled signal always, and other sampling plate is sending sampled signal always, it may be then certain sampling plate fault, now should safeguard, also be likely user's malicious sabotage sampling plate and the improper counting that causes (only has all, or the several sampling plates at least specified all produce sampled signal can think that character wheel have rotated one week, only has one, or a small amount of sampling plate generation sampled signal can not be identified mechanical character wheel 110 and rotate a circle, user can stop collector normally to work by the mode destroying fractional-sample plate, counting, and escape paying), acquisition module for remote meter reading provided by the utility model, by two, or the set-up mode of multiple sampling plate can avoid the generation of this kind of situation (to destroy part collection plate, the reading of the first sampling plate 112 and the second sampling plate 113 can be made to carry out not in accordance with the mode of regulation, thus trigger alarm).
Thus, the function of early warning can be realized by arranging comparer 114 and the first alarm 115.The namely acquisition module for remote meter reading provided by the utility model, also comprises: comparer 114 and the first alarm 115; Described comparer 114 is electrically connected with described first sampling plate 112 and described second sampling plate 113 respectively, and for when described first sampling plate 112, and/or generate the first alerting signal when the sampled signal number differences that collects of described second sampling plate 113 is greater than preset value; Described first alarm 115 is electrically connected with comparer 114, and for reporting to the police according to the first alerting signal got.
Usually, the magnetic field intensity (maximum intensity) that magnet steel 111 produces when rotating is fixing.When the magnetic field intensity that any one sampling plate collects is greater than preset value time, then illustrating that the acquisition module being used for remote meter reading receives magnetic and attacks, now should reporting to the police, as sent warning message, signal to supervision department.
The magnetic field intensity detected except sampling plate is too high, can think that the acquisition module for remote meter reading is in a point normal operating conditions, can also be to think that when some sampling plates are malfunctioning time the acquisition module for remote meter reading is in abnormal operating state (time namely the first sampling plate 112 or the second sampling plate 113 generate sampled signal continuously, can judge that the acquisition module for remote meter reading is in abnormal operating state).Namely, acquisition module for remote meter reading also comprises counter and the second alarm, described counter is electrically connected with the first sampling plate 112 and the second sampling plate 113 respectively, and for after receiving the sampled signal that two the first sampling plates 112 generate continuously, or after receiving the sampled signal that two the second sampling plates 113 generate continuously, generate the second alerting signal, described second alarm is electrically connected with counter, and for reporting to the police according to the second alerting signal got.
Between two sampled signals that appearance first sampling plate 112 generates continuously, second sampling plate 113 does not generate sampled signal, then illustrate that the acquisition module being used for remote meter reading is in abnormal operating state, now can send warning to supervision department, or trigger the alarm appliance work such as hummer.
When the acquisition module for remote meter reading is subject to intensive magnetism attack, the reading collected except sampling plate is too high, and two sampling plates can produce sampled signal usually simultaneously.The time difference of the sampled signal namely generated respectively when the first sampling plate 112 and the second sampling plate 113 is too small, then alternatively the bright acquisition module for remote meter reading is in abnormal operating state (even if water energy, or the flow process of rock gas reaches maximal value, the sampled signal that first sampling plate 112 and the second sampling plate 113 generate respectively also has the time difference, can produce sampled signal scarcely simultaneously).Namely, acquisition module for remote meter reading also comprises the first counter and the 3rd alarm, described first counter is electrically connected with the first sampling plate 112 and described second sampling plate 113 respectively, and the time difference between two sampled signals that described first sampling plate 112 and the second sampling plate 113 produce respectively is when being less than default numerical value, generate the 3rd alerting signal; 3rd alarm is electrically connected with described first counter, and for reporting to the police according to the 3rd alerting signal got.
First counter can start timing after receiving a sampled signal (as the sampled signal that the first sampling plate 112 sends), on receiving once after sampled signal (as the second sampling plate 113 sends), reset, and reclocking, until report to the police time the mistiming receiving sampled signal for twice is less than preset value.Under normal circumstances, the first sampling plate 112 and the second sampling plate 113 alternately produce sampled signal, therefore, can confirm that whether mechanical character wheel 110 is normal in rotation by the mode of the minimum time difference.
Above three kinds judge that the mode whether being in normal operating conditions for the acquisition module of remote meter reading can use simultaneously, also can only use a certain, or certain two kinds confirm whether the acquisition module for remote meter reading is in normal operating conditions.
Can also be that the acquisition module for remote meter reading also comprises the magnetic shielding box establishing hollow, it is inner that described mechanical character wheel 110, described magnet steel 111 and described sampling plate are all positioned at described magnetic shielding box.
Use magnetic shielding box can effectively avoid the acquisition module for remote meter reading to be subject to general magnetic to attack, ensure the stability of its work.
The utility model embodiment 2 provides the collector for remote meter reading, as in Figure 2-4, comprise the acquisition module for remote meter reading that embodiment 1 provides, it is characterized in that, also comprise main control module 116, described main control module 116 comprises statistic unit 1161 and display unit 1162, and described statistic unit 1161 is electrically connected with sampling plate, and generates statistics for the quantity according to sampled signal; Display unit 1162 is electrically connected with statistic unit 1161, and for showing the numeral of specifying according to statistics.
Directly can show numeral according to statistics by display module, know the amount used to make user., it should be noted that, if use two sampling plates (first sampling plate 112 and the second sampling plate 113), statistical module then thinks that mechanical character wheel 110 have rotated a circle after receiving two sampled signals continuously meanwhile.Certainly, two sampling plates need to send different sampled signals respectively, to ensure that statistical module effectively can identify two sampling plates.
Because packet is longer, wherein one or more bytes occur that the probability of error code is higher, therefore in order to avoid problem that the length of packet is long.Acquisition module for remote meter reading also comprises micropower sending module, described micropower sending module comprises data length judging unit and the data partitioning unit, data transmission unit, the packet generation unit that are connected with length determining unit respectively, and described data partitioning unit is connected with described data transmission unit;
Data length judging unit, for judging whether the length of described statistics is greater than default standard length;
Data partitioning unit, if data length judging unit is judged as YES, then according to the Data Segmentation mode preset, described statistics is divided into multiple data to be sent, and the length of data to be sent is all no more than default standard length;
Multiple data encapsulation to be sent if data length judging unit is judged as NO, then for described statistics is encapsulated as packet to be sent, or is packet to be sent by packet generation unit;
Data transmission unit, for sending packet to be sent.
Data (receive when tabling look-up information when sending, send local reading to kilowatt meter recorder), can reduce the whole bag packet loss of packet, improve the reliability of data communication by carrying out fractionation to data.When splitting data, according to the standard length preset, statistics can be divided into multiple length and equal standard length part, or statistics is equally divided into many parts.As the statistics that length is 27 bytes, standard length is 10 bytes.Can divide according to the form of 10,10,7, also can divide according to the form of 9,9,9, the former is convenient to the segmentation of data, and the latter more lays particular emphasis on the lifting of data reliability.Data transmission unit can use as RS485 bus protocol carries out data communication.And by reducing the length of packet, the penetration capacity of signal and accessible communication distance can be improved when use radio-frequency communication (RF).
The general function of micropower sending module is for communicating with radio meter register equipment (supervision department used).Radio meter register equipment comprises wireless POS and concentrator.In order to save electric energy, when micro power radio module does not work, being in dormant state, therefore when radio meter register equipment needs to communicate with collector, first must waking the wireless module of collector up.Radio meter register equipment operational order (as read statistic unit 1161 the statistics that generates) issue collector.
Further, collector for remote meter reading also comprises the second timer be electrically connected with the first sampling plate 112 and the second sampling plate 113 respectively, for at described first sampling plate 112, and/or second sampling plate 113 produce sampled signal after start timing, if and in the schedule time, described first sampling plate 112 and the second sampling plate 113 all do not produce sampled signal, then generate valve closing signal.
Long-time can carry out anti-sealing by valve-off when not using, or the leakage of rock gas or misuse.
In order to ensure that user can not maliciously usurp water or rock gas, collector for remote meter reading provided by the utility model also comprises the flux leakage detector of the collector outside surface be arranged at for remote meter reading, during for being greater than default normal intensity when the magnetic field intensity detected, generate valve closing signal.
When flux leakage detector works, then illustrate that the outer wall of magnet steel 111 is destroyed, or illustrate that user uses intensive magnetism attack to be used for the collector of remote meter reading, this can make the first collector or the second collector cause to misread, or the phenomenon that cannot read.When use flux leakage detector, and when the data that detect of flux leakage detector are too high, then user can be stoped to use water or rock gas by valve-off.
It should be noted that, after valve-off, need by the instruction set by supervision department, or valve opening card can open valve, to ensure that water resource or natural gas source can not be stolen.
Before using the collector being used for remote meter reading, usually need to use IC-card, or other rechargeable cards guarantee that user has enough remaining sums to use.Namely need to use IC-card read module to read the remaining sum in IC-card, and be stored into reservoir and gather, then after statistic unit 1161 is added up, deduct from the IC-card remaining sum reservoir.When the remaining sum of the IC-card in reservoir is 0, then can valve-off.Can also be increase to arrange balance reminding module, remaining sum sends information lower than during the numerical value preset, and supplements with money to point out user.
Power loss detection means (mainly for for the reservoir in the collector of remote meter reading) can also be increased in addition, to ensure that the data in reservoir can not be lost, and when power loss detection means works, need valve-off simultaneously.
Alarm needs energising to complete warning, display unit 1162, data transmission unit etc. are also the parts needing power supply, therefore need to increase supply module (concrete as dry cell), and by arranging voltage reminding module, whether detect the voltage of supply module lower than preset value, and send information when brownout, to make user, to charge in time, or change battery.
