Description

The beeper of beeper power saving method and use power saving method

The present invention relates generally to beeper and the electronic product of beeper is housed, particularly relate to the power saving method of beeper and use the beeper of this method.The structure of a beeper as shown in Figure 1, antenna, radio frequency receiver, decoder, central processing unit, liquid crystal display, address code holder, low battery detector, clock and other input/output units have been comprised, as loudspeaker, electromagnetic shaker, indicator light, display lighting, photoreceptor and operating key etc.

In numerous controlled function of beeper, power-save operation (power saving operation) is very important, directly affects the receptivity of beeper.Because the power supply of beeper must be connected all day, promptly be in normal on-state (normally ON state) and prepare against receipt of call at any time, but because its power supply source is a 1.5V alkaline battery (capacity is between 800mAH～1200mAH), if the function that does not have power-save operation in the circuit design then battery certainly will be consumed soon.Therefore in the beeper power-save operation function must be arranged, and in its operation instructions, illustrate under certain test condition, must how many hours to use continuously.Domestic telecommunication office regulation just for example passes in the 4430-2 material specifications book according to material that battery was at least 320 hours service time under the 3.9th the power consumption defined terms.

Present general beeper has possessed certain electricity-saving function.Because the coded format (Code format) of the signal that the power-save operation of beeper receives and transmits with beeper often is inseparable, therefore from then on narration begins earlier.The code form and the frequency of utilization of beeper that various countries use are not quite similar, POCSAG(POST OFFICE CODE STANDARDI ZATION ADVISORY GROUP) code has been acknowledged as international code, the at present domestic POCSAG standard that also adopts is notified from a phone call form, and is represented as the L among Fig. 2.Wherein notifying from a phone call and include preamble (PREAMBLE) signal in the signal, is many complete batch (BATCH) subsequently, and a synchronous character code (SYNCHRONI ZATION CODEWORD) is all arranged before each batch.That is, each batch is by a synchronous code (SC) and 8 frames (FRAME), promptly constitute from the 0-7 frame, and each frame comprises two character codes (CODEWORD), so one batch length is 17 character codes.8 frames in batch order respectively are the 0th frame to the 7 frames, and beeper also is divided into 8 groups, is subordinate to respectively in these 8 frames.The address code of beeper (ADDRESS CODEWORD) is made up of seven bit digital, accounts for 21 positions.And a position is that the position is differentiated in the address in one 32 the address character code, 18 positions are the address code data, two positions are function digit (FUNCTION BIT), 10 positions are redundant inspection position, school (REDUNDANT CHECK BIT), add an even parity and become the address code transmission, and last three positions belong to that a group in order to distinguish this address, are divided into into 8 groups.Beeper only checks in affiliated frame whether address code information is identical with address own, if identical just can receive along with and the information word codes (MESSAGE CODEWORD) of coming, information word codes can be random length and can extend to next batch (but the synchronous code of this batch can not be omitted).The information of beeper is as end with next address code or empty number (IDLE CODE).

Because beeper does not need to receive whole batch information, only in the frame that is subordinate to, just have one's own information, and also will be through the inspection of address code.Therefore, the power supply of beeper does not need the long run supply radio frequency receiver, only needs a small amount of power supply to keep the groundwork of central processing unit (CPU), the electricity-saving function of Here it is POCSAG notifies from a phone call form.Its process is as follows:

After beeper is received preamble (PREAMBLE) signal, the radio frequency receiver power supply can keep connecting just outage after the synchronous code of receiving first batch always, when promptly the frame under this beeper occurs subsequently (as shown in the figure, this beeper for example is in the 3rd frame) just connection automatically again of power supply, decoder this moment (DECODER) can check whether the information of being received conforms to the address code of beeper, if be not inconsistent then after one very short period, power supply automatically outage when next batch synchronous code occurs, power supply is just connected, and can cut off the power supply again after synchronous code.If the address character code in the decoder discovery information is identical with beeper, this beeper of expression forward sends information, and then the power supply of beeper keeps connecting, till the end of message.So, rely on to make power supply connect discontinuously and cut off the power supply like this, make the big radio frequency receiver of power consumption not need continuous operation, and only need keep the groundwork of central processing unit with a small amount of power supply, guarantee necessary monitoring function.Therefore, reached certain power saving purpose.

In Fig. 2, the source current oscillogram when A and B schematically illustrate beeper by POCSAG standard power-save mode of operation.Wherein, oscillogram A does not have the address of this beeper and the situation of information when notifying from a phone call in the signal; Oscillogram B has the address of this beeper and the situation of information when notifying from a phone call in the signal.Its power-save operation period T is not 1.0625 seconds when beeper is received preamble (preamble) signal that transmitting station sends, and radio frequency receiver power connection (i.e. " power-save operation disconnection ", power saving " OFF ") time theory value P is 62.5mS, be that its occupation efficiency (Duty cycle) is 1/17, but in fact because of considering that beeper receiving that notifying from a phone call signal postpones for some time to demonstrate message on display, for power supply in making during this period of time keeps stable on-state, historical facts or anecdotes border P value is about (being that occupation efficiency is between 1/13 to 1/10) between the 82mS to 106mS.And after beeper is received the preamble signal, power supply will keep connecting always, after the synchronous character code of receiving first batch, just disconnect, the i.e. just connection automatically again of power supply when occurring of group's (frame) under this beeper subsequently, this moment, decoder can check whether institute's message of receiving equates (promptly whether be call out to this beeper) with the address code of this beeper, as if being inconsistent then in P power supply automatic disconnection after the time (A situation in as Fig. 2) just connection once again when the second batch synchronous character code occurs.The theoretical value of beeper its power connection in each batch after receiving the preamble signal is 3/17 T as from the foregoing, but in fact the time of power connection between 1/4T～1/3T.Shown in B situation among Fig. 2, if decoder finds that the address code in the 3rd frame is identical with the address code of beeper, then be illustrated in and call out this beeper, if having information then the power supply of beeper can continue to keep connection for this reason up to the end of message.Because it is required only to consume about 50 μ A(CPU during " power saving connection " (power saving " ON ")), and it is required to consume about 5mA(radio frequency receiver, decoder, central processing unit etc. when (" power-save operation disconnection ")).Thus, known power-save operation is that beeper has been saved certain electric energy battery is prolonged useful life.

But, above-mentioned general POCSAG notifies from a phone call the normal power-saving operation method thereof of form and not in full conformity with ideal, particularly can not and use needs reach further power saving requirement, thereby make power supply energy very limited in the beeper better be saved and fullest, effectively utilize according to the beeper applied environment of multiple reality.

Therefore, the objective of the invention is on the basis of the normally used standard P OCSAG power-save operation of beeper mode, according to the beeper environment for use and the use needs of multiple reality, propose further to save the multiple new power-saving operation method thereof of beeper power supply, and the beeper that uses this method.

Wherein, in the explanation of specification previous section, now will at first continue to narrate the present invention about Fig. 2 in conjunction with Fig. 3.

Situation when Fig. 3 a and 3b are the standard P OCSAG power-save operation of prior art and remote control power-save operation of the present invention respectively.

In Fig. 3 a and 3b, the data format in the signal is notified from a phone call in top figure representative, and following oscillogram is represented the source current impulse waveform of beeper.In the data format of notifying from a phone call signal, P represents preamble (preamble), and SC represents synchronization character, and F5 represents the 5th frame.The address of supposing beeper is to belong to the 5th group.The situation among the analysis chart 3a at first, after beeper is received the preamble signal, the central processing unit of beeper is according to fixed design, control beeper power supply keeps connecting always, just outage after the synchronous code of receiving first batch, i.e. just connection automatically again of power supply when the 5th affiliated frame occurs subsequently.Whether the address character code in the decoder inspection message identical with beeper, determine the address after, then the power supply of beeper keep to be connected till the end of message.When the 5th frame in each synchronous code and each batch occurred, power supply can be connected automatically.

The mains switch of beeper radio frequency receiver is controlled by central processing unit by the power-saving control line.Central processing unit can remove to control the switch of radio frequency receiver according to set electricity saving method.According to the standard of pocsag code, its only can be at preamble, opens the power supply of receiver on the position of synchronous code and suitable frame, and signal is picked up in inspection.The arrangement of pocsag code is after one section preamble, and then the back have many batch.All comprising 1 synchronous code and 8 frames in each batch, 2 character codes are all arranged in each frame, these character codes can be that address code can also be an information code.All beepers all are divided into 8 groups, and the address code of every group of beepers only can occur in its corresponding frame, so every beeper only needs therein to open in the frame power supply of receiver, just can receive the address that belongs to it and information.In gross, include only preamble, synchronous code and one of them frame in the time that radio frequency receiver is opened.

They more than be the electricity saving method of standard P OCSAG beeper, but on the beeper of having implemented electricity saving method of the present invention, its method is just different:

After power-saving control bundle of lines receiver is opened, antenna just can be examined and pick up signal (being mixed with the frequency modulation signal of address code and information code), and radio frequency receiver is just this signal demodulation, at first demodulation is address signal, receiver just passes to decoder to this signal and goes decoding after the demodulation, then with machine in address code (storage in the address code holder) check mutually, if the address is identical, receiver can continue the information code signal demodulation subsequently, and they are sent to decoder go decoding.

The signal that decoder is received is the signal according to the POCSAG standard code.Comprising 1 discrimination bit (Message Bit), 20 information bits (Iinformation Bits), inspection position, 10 redundant schools (Redundant Check Bit) and 1 even parity (Even Parity Bit).The decoding program of decoder be at first utilize inspection position, 10 redundant schools error bit is detected and corrects (if any words).And then just check discrimination bit, if " 0 " represents that this sign indicating number is an address code, information bit just can be checked mutually with address code in the machine so, just signal continuation is subsequently decoded as if identical, otherwise just notify central processing unit that radio frequency receiver is closed, treat to open again proper time.When if information bit is " 1 ", promptly this sign indicating number is an information code, just decoder is given central processing unit 20 information bit decodings.

After central processing unit is received information code, just they are deposited in the memory, and also can take out the time from clock, together deposit in the memory.Ring when making a noise if alert mode is set at, central processing unit just triggers loudspeaker, makes it to send the alarm audio frequency, and the announcement machine master has message to receive.When if alert mode is set at vibrations, central processing unit just triggers electromagnetic shaker and makes it vibrations, and the machine master of informing has message to receive.If when alert mode was set at peace and quiet, central processing unit just can not trigger loudspeaker or electromagnetic shaker, comes the announcement machine master to have message to receive and only flash indicator light.During alarming, if there is any button to be pressed, alarm just can stop immediately.If there is not key to be pressed, alarm also can stop after the regular hour automatically.

When sending alarm, central processing unit also can be message and reception time showing on LCD, when alarm by by after stopping or stopping automatically, message still can show a period of time, the machine master of allowing has the enough time to remove readable message.If during the message demonstration, photoreceptor detects insufficient light, just central processing unit can trigger the display lighting device, allows the machine master still see message under the environment of insufficient light well.Finish when message shows, central processing unit just can be turned off display lighting, changes into simultaneously showing other data, for example time etc.

The message that is stored in the memory can be read at any time, as long as by button, message just can be presented on the liquid crystal display.The storage of message is to arrange with the method for " afterwards going into earlier ", and a message of promptly receiving at last is the message that article one shows when reading.After article one message was read, if button is pressed again, next bar message just can show, and stops until button, and the message of reading at last just can show a period of time, changed into then showing other data.

As in beeper operating period, when low photodetector detects cell voltage and is lower than operant level,, and on display, show low electric warning message just central processing unit can send alarm, the announcement machine master changes battery.This low electric warning can be sent frequently, till the machine master changes electricity.

On the beeper of having implemented the digit key control method, reading aspect the message, be the numerical key that utilizes on the machine, directly required message number input and take out message, need not to read one by one by the order of " afterwards going into earlier ".Utilize 10 numeric keys to cooperate " Page Down keys/enter key ", just can reach the effect of function selecting according to the figure place of numeral.

Figure below of Fig. 3 b is the beeper source current oscillogram that first kind of power saving working method of the present invention is remote control power-save operation mode.The method according to this invention sends information by paging station to beeper, and the order beeper temporarily stops to receive the some time, and the radio frequency receiver circuit is closed, and CPU also enters sleep state, only keeps limited function.After some time, normal accepting state is replied in the CPU recovery.This power saving mode is used for night or festivals or holidays more, makes the beeper discontinuous operation.Because in this time, the number of times that beeper is sent information is less, if receive information with normal power-save operation, beeper still must be when each synchronous code and the frame under each occur, all to allow radio frequency receiver connect once, because information is not busy, beeper does not have receivable information usually, therefore receives according to normal power saving mode still to belong to waste.

According to the present invention, when beeper control enters remote control power saving mode, operating process is as follows: because in the signal that paging station sends this beeper, comprise the time (not waiting to a few hours by several seconds usually) of this remote control suspend command and dwell interval in the information word codes after the character code of address.Generally speaking, when beeper occurs at affiliated frame, just can be with the power supply opening of radio frequency receiver, and make the CPU operate as normal, reception information.Whether by the decoder inspection is the address character code, if the address character code, whether with machine in address identical, if the identical information word codes that then reads subsequently if checking this address again.Now, after using this method, if paging station sends the remote control suspend command to beeper, it is a remote control suspend command that CPU just can discern this information, and controls each relative assembly according to this order immediately, carries out relevant procedures.At first, turn-off the power supply of radio frequency receiver, make CPU enter sleep state simultaneously, only keep the limited function that clock in the machine is made timing controlled and kept CPU, calculate downtime and at the fixed time after beeper is revived, operate according to normal power saving mode.

For example, at first send one to beeper and stop the remote control suspend command of reception (for example 30 seconds) by paging station.Therefore, shown in the data format figure above among Fig. 3 b, in notifying from a phone call signal, in the address of the 5th frame character code part, arranged public address (using using), and in the information word codes part, arranged to stop the order of reception in 30 seconds for all relevant beeper identifications.Beeper is in service in the POCSAG power-save operation, and the address character code of oneself is picked up in inspection in affiliated frame, has received information subsequently simultaneously.It is the guidance command that stopped to receive in one 30 seconds that CPU discerns this information, just immediately according to these command execution relevant procedures, that is: with the power cut-off of radio frequency receiver, CPU keeps limited function (promptly, enter the state of power saving mode), and set the timing controlled that clock-inside began 30 seconds.When arriving in 30 seconds, be about to all functions and recover, the radio frequency receiver power supply is connected automatically, just outage again after receiving synchronous code then, and like this, beeper is just by first kind of power saving method of the present invention, i.e. remote control power saving method and realize power-save operation.

Change the regularly narration of power-save operation mode below over to.

Regularly the similar part of power saving mode and remote control power saving mode is, its objective is to make the beeper discontinuous operation.For example, just stop radio frequency receiver work in the official hour, do not receive information in every day.Every day is like this, till the timing suspend command is removed.There is part machine master after work or do not have message pick-up night (in bed), all likes beeper is closed, again beeper is opened in morning on next day for power saving.But all can forget when a lot, that is, otherwise be exactly to forget shutdown, the waste power supply; Otherwise be exactly to forget start, information not available.Regularly the power saving mode proposes at this point.Beeper can calculate correct switching time according to clock-inside after accepting regularly suspend command.

Realize that regularly the power saving mode has following several:

When A. being produced by the design of beeper manufactory, will configure downtime, close radio frequency receiver and keep the limited function of CPU every day at one time, and in another time beeper is recovered operate as normal.This program has been fixed in the beeper function, can not freely revise, and must transfer to manufactory or change is responsible in the service station.

B. send order by paging station to the beeper with this function, the order load mode is the same with transmission remote control suspend command.Except that order, also comprise power-off time and opening time in the information.The CPU of beeper discerns this information for behind the suspend command regularly, just the data storing that receives subsequently can be got up become shut-in time and open-interval criterion.CPU calculates the real time according to clock-inside, and when arriving the shut-in time, CPU just carries out power saving program, and to the opening time, CPU can carry out functional recovery routine.Even can notifying paging station to revise, the machine master cancels this function switching time.

C. if beeper is the digit key control beeper, can utilize numerical function key and enter key, select to enter regularly battery saving mode, import private password after, utilize numerical key input power-off time and opening time again.So CPU just can as described in the B item according to the time carry out relevant procedures.Certainly, the machine master can change the time at any time or cancel this function.

Below, for the typical regularly power-save operation mode of the present invention is described, at first need to illustrate a kind of beeper that adopts the digit key control method.This power-saving operation method thereof promptly can be realized on this beeper.Fig. 4 is a kind of outline drawing that adopts the beeper of digit key control method, and there are three buttons in the front of fuselage, and the label according to this figure is respectively: 1, on move key; 2, move down key; 3, play the Page Down keys that " Page Down keys/enter key " acts on.In addition, also have ten numerical keys that play " numerical key/function key " effect, they itself have indicated numeral 0 to 9 respectively on fuselage.Its basic function is described as follows:

Key name claims function

Numerical key/input of function key numeral or function selecting (being used) by enter key

On move key and select to show a last information

Move down key and select to show next bar information

Page Down keys/enter key information exceeds the length of screen display, reads next by this key

Page or leaf.When generally not having reception, this key can cooperate

Each key becomes numerical key or function key.

Press any one numerical key (among the digital 0-9), i.e. a kind of function is set in expression, and wherein, for example numerical key 1 is set at the password processing capacity.By pressing numerical key

, press enter key again

Operation promptly imported the command function of an expression password processing capacity.And for example, by pressing numerical key

, press enter key again

Operation, promptly imported an expression and carried out the regularly command function of electricity-saving function.

Fig. 5 realizes the regularly flow chart of the principle of power-save operation function on the beeper that adopts the digit key control method.

Program begins, and beeper machine master at first selects regularly power-save operation function by numerical key on the beeper panel and operating key, and after this function was selected, standbies such as beeper are main then imported correct password.After the machine major key is gone into password, program in the beeper just checks whether this password is correct, as correctly, then to next step program: power-save operation time started that the receiver major key is gone into (for example: afternoon 5:00) and termination time (for example: the morning 9:00), so beeper just automatically performs province's electric energy in this official hour section.If the password that the machine major key is gone into is incorrect, then beeper does not enter next step program, and the machine master of requirement keys in password again, and the password of keying in checked, if machine master continuous several times (for example, 8 times) the key error password, then beeper enters frozen state automatically, promptly temporarily freezes the general utility functions of beeper.

Fig. 6 is the beeper source current waveform schematic diagram of explanation timing power-save operation mode of the present invention.Wherein, Fig. 6 a is that the page message data format and the source current oscillogram of standard P OCSAG power-save operation mode (is same as Fig. 3 a), in order to contrast with the timing power saving mode of the present invention shown in Fig. 6 b.In the data format of the last figure of Fig. 6 b, the user profile of supposing this beeper is at the 5th frame, and the hypothesis beeper is by the present invention's power-save operation regularly, from afternoon 5:00 to the morning 9:00 be the power-save operation time, thereby make beeper set the reception time be the morning 9:00 to 5:00 in afternoon.After beeper is opened, be, and receive a real-time signal, with the real time in the adjustment machine at affiliated frame according to the operation of POCSAG power-save operation.If this real-time signal is 9:00 in evening, the radio frequency receiver of beeper just quits work immediately, and CPU begins to calculate with clock-inside and real time, arrives 9:00 in the morning when the time, CPU can recover all functions of beeper, and moves according to the POCSAG power-save operation.Therebetween CPU still in the real-time signal of calculating the real time and receiving paging station to adjust.To afternoon the 5:00 beeper can enter automatically and stop accepting state.Just recovery operation of 9:00 next day.

Change over to more below the narration of power-save operation mode in batches.

Fig. 7 illustrates the beeper source current oscillogram of power-save operation mode in batches, among the figure, Fig. 7 a is the page message data format and the beeper source current waveform schematic diagram of standard P OCSAG power-save operation mode, and Fig. 7 b is the message data format and the power supply wave shape figure of the mode of power-save operation in batches of the present invention.Among the figure, the user profile of this beeper of hypothesis is at the 5th frame in the standard power-save mode, and in the present invention's power saving mode in batches, supposes that user profile is the 5th frame at the 2nd batch.When the standard power-save mode, beeper all will receive once at each batch.And the mode of power-save operation in batches of the present invention is different therewith, beeper user's information only regulation batch in occur, so beeper only needs batch receiving in this regulation.For example, in Fig. 7 b, the address code of regulation beeper belongs to the 5th group, and specifies it only with reception information in the 2nd batch.Beeper is according to the operation of POCSAG power-save operation, and power supply can keep connecting always after receiving the preamble signal, subsequently outage.CPU just begins to calculate the occurrence number of synchronous code after receiving the preamble signal, determine it is that batch.When receiving the 2nd synchronous code, CPU represents that promptly this batch is the 2nd batch, so the power supply of radio frequency receiver is connected automatically when the 5th frame occurs, and reception information.

Therefore, power saving mode in batches is that the power-save operation of the POCSAG form of standard is more pushed to one deck.Still when synchronous code occurs and under in the frame power supply just connect, and can select appointment behind the preamble signal which batch under frame when occurring, the power supply of radio frequency receiver is just connected, that is, be not that frame under in each batch is all connected when occurring.Some information, for example public information can not change constantly, and the number of times of transmission is not frequent, or the data that send are often the same with last time, so when beeper just need the frame under each occur, power supply was all connected inspection message.This power saving mode can cooperate the transmitting time of paging station to design beeper, and when the affiliated frame of beeper in effective batch occurred, power supply was just connected, and improves the operating efficiency of radio frequency receiver greatly and battery is prolonged useful life.

In a word, the implementation of power saving mode in batches is: set the power connection of that batch ability of this beeper after receiving the preamble signal with radio frequency receiver by beeper manufactory according to the character that will receive information, at other times, the power supply of radio frequency receiver is for disconnecting, and CPU keeps limited function.And paging station also can cooperate this beeper, will send in the frame under the format that send is in its suitable batch.Beeper is after power-on, and power supply keeps connecting just outage after receiving the preamble signal and receiving the synchronous code of first batch always, connects when the synchronous code of next batch occurs again, and cuts off the power supply to synchronous code again.The number of times that CPU just occurs according to preamble signal and synchronous code determine oneself batch, and preparation when affiliated frame occurs with the power connection of radio frequency receiver, reception information.To have paging station can determine the preamble signal voluntarily when sending information after what batch, after each batch sends, can heavily cover again and send the preamble signal and reach batch.Beeper just with these signals as benchmark.

Fig. 1 is the structure principle chart that can adopt the beeper of power saving method of the present invention.As shown in the figure, this beeper has comprised antenna, radio frequency receiver, decoder, central processing unit, LCDs, holder, low battery detector, clock and other inputs, output device are as loudspeaker, electromagnetic shaker, indicator light, display lighting, photoreceptor and a supervisory keyboard that possesses 10 numerical keys and 3 operating keys.This keyboard includes and is used for the numerical key that digital input and function are controlled, and with the operating key of numerical key cooperating.In using the beeper of timing power-save operation mode of the present invention, supervisory keyboard also comprises the time that is used for the incoming timing operation and the device of private password.The label of numerical key is 0-9, and a numerical key can cooperate operating key to make to be used for controlling one or more functions.The effect of operating key is directly to control the basic function of beeper, for example shows an information, shows next bar information and shows a page information etc.And operating key also possesses the function that cooperates numeral, makes numerical key have both the purpose that digital input and function are controlled thereby reach.In addition, some part of this beeper or function are as described previously, and be or similar with hereinbefore described beeper.

The whole operation of beeper all is subjected to central processing unit control.Central processing unit and memory component devices and the internally stored program except having conventional design so that control is exhaled outside the general operation function of biography machine, also has according to various designs required for the present invention and structure, thereby guarantees that the inventive method is achieved on beeper.Below, specifically illustrate the course of work of such beeper in conjunction with Fig. 1.When signal is picked up in the antenna inspection, radio frequency receiver is just this signal demodulation, radio frequency receiver comprise be used for demodulate reception to the information code of frequency modulation signal and the demodulating equipment of address code, radio frequency receiver also possesses the receiving function of stopping, in order in the power saving time in above-mentioned three kinds of power saving modes, temporarily stop to receive, reach power saving effect.Radio frequency receiver also possesses the receiving function of stopping, specifically, have in the radio frequency receiver when central processing unit and receive freeze command or accept the password of input and when entering frozen state when beeper, the control device that the receiving function of whole radio frequency receiver is temporarily freezed.When the radio frequency receiver operate as normal, at first demodulation is address signal, radio frequency receiver just passes to decoder to this signal and goes decoding after the demodulation, then with the machine of being stored in the address code memory in address code check mutually, if identical, receiver can continue the information code signal demodulation subsequently, and is sent to decoder and goes decoding, by being arranged on decoding device special in the decoder, just can finish this function.In the beeper that adopts the digit key control method, memory includes the storage device of the modifiable private password of storage; Store the storage device of modifiable address code; And the storage device that is used to store personal information and public information.In the beeper of using remote control power saving mode of the present invention, timing power saving mode and batch power saving mode, then memory also should comprise respectively: the receiver of storing modifiable remote control electricity saving method is reopened receiver outage and the device of the time of reopening and the device of storing the batch number number of modifiable power saving mode in batches of the device of time, the modifiable timing power saving mode of storage.The storage of personal information and public information layout according to numbering, for example: the numbering of personal information is 01-99, and the numbering of public information is 001-999 or 0001-9999, and therefore the figure place that reaches by input digit decides the purpose of checking information number.

According to the present invention and adopt the address code of the beeper of digit key control method to change by the machine master, by being arranged on the special arrangement in the central processing unit, just can finish this required controlled function, that is, make the new address code of importing by the proper operation step of the inventive method regulation reach the old address sign indicating number of internal memory in generation (renewal) memory.Specifically, central processing unit has the control device that the internal storage data that is used for making described private password storage device, address code storage device and decoding password storage device upgrades according to the keyboard input.So, can import voluntarily or change by the machine master by the address code in the numerical key input beeper.The method of input is at first to import private password (Password), if password is correct, confirms whether to need to change positive address again, if, making the new address of input, beeper is from then on the reception of new address, otherwise the address is constant, and beeper continues with the old address reception.If the password of input is not right, just need re-enter password, if the input error password is more than n time (n is the integer greater than 1), beeper just can enter frozen state, and general utility functions temporarily lost efficacy, and the step that needs process " thawing " is functional rehabilitation.The step of " thawing " is at first to import private password, if password is correct, just call is thawed, and recovers all functions.If password is not right, just need be pressed into password again, if enter password make mistakes cross n time (n is the integer greater than 1) more, beeper just can enter partial frozen state, at this moment, has only beeper is sent back to the call center, with special thawing equipment, could recover all functions.By being arranged on the special arrangement in the central processing unit, just can realize with in the beeper memory the private password of internal memory come the private password of verification by keyboard input, thereby the control beeper makes it carry out normal every feature operation (when entering password when correct); Perhaps, make beeper freeze the normal running function (when as mentioned before, several times are all during the input error password in succession) of beeper by previously described freezing method.

In addition, private password more can utilize numerical key to make alterations.The step of change is an enter old password at first, if password is correct, just enter new password is imported the back new password and is come into force, after this password just transfers new password to by old password, if in the process of enter old password, password is not right, just needs to re-enter, cross n time if in input process, make mistakes (n is the integer greater than 1) more, beeper just can enter frozen state, and general utility functions temporarily lost efficacy, and the step that needs process " thawing " is functional rehabilitation.By being arranged on the special arrangement in the central processing unit, just can finish needed controlled function: promptly, make in accordance with regulations the proper operation step and the new password imported reaches the old private password of internal memory in generation (renewal) memory.Specifically, central processing unit has and is used for the private password verification of the internal memory private password by the keyboard input, thereby the password calibration equipment of its normal running is carried out or freezed to the control beeper; Be used for docking the signal that freezes of receiving signal and decode, and remove to control the freezing plant that beeper freezes its normal running function according to the freeze command of decoding; And be used to control radio frequency receiver, keyboard, display and other import/go out device suspends its function under frozen state device.

The signal that decoder is received is the signal according to the POCSAG standard code.Comprising 1 discrimination bit (Message Bit), 20 information bits (Information Bits), 10 redundancy check bits (Redundant Check Bits) and 1 even parity (Even Parity Bit).The decoding program of decoder be at first utilize inspection position, 10 redundant schools error bit is detected and corrects (if any words).And then just check discrimination bit, the words of " if 0 ", represent that this sign indicating number is an address code, information bit just can be relative with address code in the machine so, if identical, just signal continuation is subsequently decoded, otherwise just notify central processing unit that radio frequency receiver is closed, treat to open again proper time, if when information bit is " 1 ", be that this sign indicating number is an information code, decoder is just given central processing unit 20 information bit decodings.

Be provided with the information that beeper received of numerical key, can encode with scrambling coding (encryption) method.Like this, the transmission of information just reaches secret effect, even other people " intercept " arrives information, if there be not " decoding password ", also can not separate real information.Therefore, in central processing unit, be provided with the decoding password that is used for reading process information encrypted that decoder sends here and stores according to memory to its device that is decrypted.

" the decoding password " of each beeper can be different.The user can utilize numerical key oneself " decoding password " input or change, notifies the call center that signal is encoded by corresponding " decoding password " then, and the transmission of information just reaches maintaining secrecy of individual so.The input step of decoding password is at first to import private password, if password is correct, and then just can input the decoding password, after the new decoding password input, the control of the special control device that is provided with by central processing unit, just replace (renewal) former old decoding password that has been stored in the memory, thereby this new decoding password is come into force, beeper is decoded with new password, specifically, central processing unit has and is used for receiving the decryption device that signal is decrypted through the signal of encrypting with the butt joint of the decoding password of internal memory.If during the private password of input, password is not right, just need to re-enter, if input makes mistakes more than n time (n for greater than 1 integer), beeper just can enter frozen state, and general utility functions temporarily lost efficacy, and the step that needs process " thawing " is functional rehabilitation.The step of " thawing " is referring to above.For this reason, in central processing unit, be provided with special device, be used for after beeper enters the state of normal running disabler of the frozen that is beeper of described general utility functions, private password with internal memory removes the private password of verification by the keyboard input, when the two is consistent, then beeper recovers operate as normal; Make mistakes continuously when entering password and reach (n for greater than 1 integer) n time, beeper just can enter partial frozen state, at this moment, all functions just can complete failure, have only beeper is sent back to the call center, thaw by special thawing equipment, could recovery operation.Specifically, in central processing unit, have and be used for after beeper enters the frozen state of described normal running function, with the private password of the private password proof keyboard input of internal memory, thus control beeper enabling function or enter the control device that needs could recover the state of its normal running function by the thawing equipment of call center.

Adopt the beeper of timing power saving of the present invention or remote control power-save operation mode, in central processing unit, also comprise: make the timing power-saving instruction of input or the data of remote control power-saving instruction deposit storage device in, and clock-inside is carried out the regularly suspend command processing unit of setting; According to the timing signal that clock-inside is set, make beeper enter the power-save operation mode and return to the suspend command final controlling element of normal mode of operation.And in adopting the beeper of described three kinds of power-save operation modes of the present invention, clock-inside also comprises respectively according to the timing power saving data of remote control power-saving instruction, input or batch number in batches and carries out the device that regularly is provided with.

In addition, for preventing beeper information leakage when losing or when in machine master hand, not grasping, just need a remote control freezing function.This function is by launching a freeze command, the partial function of beeper is temporarily freezed (making it to lose efficacy), so-called freeze command is exactly with special order of information representation, after beeper was frozen, the step of having only process " to thaw " could recover normal.For this reason, in central processing unit, be provided with special setting, be used for docking the signal that freezes of receiving signal and decode, and remove to control beeper, freeze its normal running function, promptly enter frozen state according to the freeze command of decoding.

After receiving the information code that comprises various information (as: personal information and common information) when central processing unit, just they are deposited in the memory, and also can take out time data, together deposit memory in from clock.If central processing unit just triggered loudspeaker when alert mode was set at loud making a noise, make it to send the alarm audio frequency, the announcement machine master has message to receive.When if alert mode is set " vibrations ", central processing unit just triggers electromagnetic shaker and makes it vibrations, and the announcement machine master has message to receive.If when alert mode was set at " peace and quiet ", central processing unit did not just trigger loudspeaker or electromagnetic shaker, and only glittering indicator light comes the announcement machine master to have message to receive.During alarming, if there is any button to be pressed, alarm just can stop immediately.If there is not key to be pressed words, alarm also can stop after the regular hour automatically.

When alarm is sent, can't instant playback go out information on the display, generation and what show is the enter password sentence language of (Password) of requirement user.At this moment, if the password that the user is pressed into is correct, information just can show, otherwise the user needs to enter password again again, till correct.But if the password input makes mistakes cross n time (n is the integer greater than 1), beeper just can enter frozen state more.The user needs to go beeper is thawed through " thawing " program.Therefore, in central processing unit, have be used to control that display does not show at once and device that the machine master of requirement at first enters password after collecting mail under the pattern that this demonstration is maintained secrecy.

When alarming quilt by after stopping or stopping automatically; message still can show a period of time; the machine master of allowing has the enough time to remove readable message; if during the message demonstration; photoreceptor detects insufficient light; central processing unit just can trigger the display lighting device, allows the machine master can still see message well under the environment of insufficient light.Finish when message shows, central processing unit just can be turned off display lighting, changes into simultaneously showing other data, for example time etc.

The message that is stored in the memory can be read at any time, as long as by button, message just can be presented on the LCDs.The storage of message is to arrange with the method for " afterwards going into earlier ", that is to say, an information of receiving at last is the message that article one shows when reading.After article one message was read, if button is pressed again, next bar message just can show to come, and stops until button, and the message of reading at last just can show a period of time, changed into then showing other data.

On the beeper that uses the digit key control method, reading aspect the message, it is the numerical key that utilizes on the machine, by directly message being taken out in required message number input, need not to read one by one by the order of " afterwards going into earlier ", utilize 10 numerical keys to cooperate " Page Down keys/enter key ", follow the effect that just can reach function selecting according to the figure place of numeral.This function also is to realize by the special arrangement that is arranged in the central processing unit, specifically, in central processing unit, has the memory information numbering storage of the storage device that is used to make described personal information and public information and the control device of demonstration is provided according to the control of described digital keys.That is: at first by control, make information code data reception, representative various personal informations and public information classification and numbering and being stored in the memory according to the rules; Secondly,, a certain specified information is taken out, offer display screen and show (as narrating in conjunction with Fig. 1 in the preamble) according to the control of digital keys.Therefore, in central processing unit, also has the device that is used for supervisory keyboard and discerns its digital input, function selecting and digit; Thereby the beeper that makes the Applied Digital keying is achieved described all novel capabilities.And, when message shows, more can utilize numerical key requirement user to enter password earlier (Password), ability show message after the confirmation shows the effect of maintaining secrecy thereby reach.If make mistakes in the program of entering password more than n time (n is the integer greater than 1), beeper just can enter frozen state, and partial function temporarily lost efficacy, and the user need remove restore funcitons through " thawing " program.

More than, the explanation only concrete, that preferred embodiment is made the present invention by some.But the present invention is not subjected to the limitation of these embodiment, and those of ordinary skill in the art can make modification miscellaneous or modification to the present invention according to spirit of the present invention, but they all can not depart from the scope of the present invention.
