Abstract
To ensure the low voltage alarm operation of a system section and the backup of reception information by detecting that a battery voltage is dropped to any of three stages of prescribed voltages so as to control the alarming operation, the operation of the system section and the stop of the operation of all the functions of the system section. When a 1st detection circuit 14 detects that the voltage of a battery 13 is dropped up to the low voltage alarm starting voltage of a system section 11 receiving an individual selective signal from a base station and displaying the signal or the like, the low voltage alarm operation of the system section 11 is activated in response to a detection output 14a. Moreover, when a 2nd detection circuit 15 detects that the voltage is dropped up to the backup start voltage of reception information, the system section 11 is activated in the backup mode and when a 3rd detection circuit 16 detects that the battery voltage is dropped up to the reset starting voltage, all the functions of the system section 11 are stopped. Thus, the backup of the reception information is ensured during the low voltage alarming of the system section.

The present invention introduces a kind of at the selective call receiver individual, that use in the selective call radio communication system, concrete introduce to have detect cell output voltage function of using at present and the selective call receiver of supporting paid-in informational function.
Accompanying drawing 4 expression is according to prior art, at the circuit structure of the selective call receiver individual, that use in the selective call radio communication system.In the accompanying drawing 4, digital 41 representatives have that the execution preliminary treatment-as the components of system as directed of demonstrations-function, it receives individual selection signal from base station; 42 is storage devices of the information that has been received of a storage; The 43rd, battery provides electric energy for components of system as directed 41, and 44 is voltage detecting circuits, in order to detect the voltage that battery 43 puts on components of system as directed 41.Be lower than predetermined voltage when voltage detecting goes out the voltage that electric circuit inspection goes out battery, the detection signal that then starts the low pressure alert action just is transported to components of system as directed 41 from voltage detecting circuit 44.
Below the operation principle of the selective call receiver of above-mentioned routine is made an explanation.With reference to the accompanying drawings 4, when the output voltage of battery 43 was lower than for the necessary predetermined voltage of components of system as directed 41 operate as normal, the detection signal 44a that then starts the low pressure alert action will be transported to components of system as directed 41 from voltage detecting circuit 44.So components of system as directed 41 is carried out the low pressure alert action, and enter the mode of operation of the information that support has been received.Yet the voltage detecting circuit 44 that is comprised in the conventional selective call receiver can only detect the output voltage of battery when output voltage is reduced to predetermined voltage.Correspondingly, during the low pressure alert action and the information that has received when being supported, voltage detecting circuit 44 can not detect from battery 43 and be applied to voltage on the components of system as directed 41.Therefore, when supply voltage (being the output voltage of battery) when constantly descending, can produce a problem, promptly the function of components of system as directed 41 reduces, and perhaps, components of system as directed 41 goes wrong, thereby can not normally support the information that received.
The present invention can solve above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of selective call receiver, and components of system as directed wherein can be guaranteed the low pressure alarm and the support of the information that received operation, descends irrelevant with the output voltage of battery.
For achieving the above object, according to the present invention, the selective call that is provided receives and comprises: one first voltage detecting circuit, be reduced to first voltage level in order to the output voltage that detects battery, and make components of system as directed carry out the low pressure alert action; One second voltage detecting circuit is brought down below second voltage level of first voltage level in order to the output voltage that detects battery, makes components of system as directed be in the state of the information operating that support received; A tertiary voltage testing circuit is brought down below the tertiary voltage level of second voltage level in order to the output voltage that detects battery, makes components of system as directed carry out reset operation.
In addition, selective call receiver of the present invention also can comprise a conversion control circuit, is used for making components of system as directed according to the having or does not have of the information that has received, starts the low pressure alert action and the support of the information that received is operated.
Therefore, according to the present invention, when the output voltage of battery was reduced to first voltage level, first voltage detecting circuit was started working, and made components of system as directed carry out the low pressure alert action.When the output voltage of battery was further reduced to second voltage level, second voltage detecting circuit was started working, and reduced the function of components of system as directed, and the information support operation that components of system as directed has been received.Under the state that the information that has received is supported, if the output voltage of battery is reduced to the tertiary voltage level, components of system as directed can't be operated, then the tertiary voltage testing circuit is started working, the whole functional of halt system part.So, guaranteed that the information that has received is supported.
In addition, according to having or not of the information of judging reception, also can obtain following advantage.That is: under the situation of the information that does not need to support to have received, the control transformation control circuit, thus make components of system as directed only when cell output voltage is reduced to second voltage level, just carry out the low pressure alert action.Thus, can prolong the apparent lifetime of battery.

3Relation.
The operation principle of present embodiment below is described.
Under present embodiment was normal operation, the output voltage of battery 13 at first was higher than low pressure alarm starting resistor V
1Because components of system as directed and other part consumed powers, the voltage of battery 13 just can descend, as shown in Figure 2.When the output voltage of battery 13 during to working point 21, first voltage detecting circuit 14 is started working, and 14a is sent to components of system as directed 11 with low pressure alarm enabling signal.Components of system as directed 11 1 receives this signal 14a, just can start the low pressure alert action.
During components of system as directed was carried out the low pressure alert action, the electric energy that stores in the battery 13 was consumed, so the output voltage of battery 13 descends.When the output voltage of battery 13 was reduced to the working point 22 of accompanying drawing 2, second voltage detecting circuit 15 was started working, and supported operation start signal 15a to be sent to components of system as directed 11 information.Components of system as directed 11 1 receives this signal 15a, just begins the MIN running that allowed, reduces the function of components of system as directed 11, and enters status of support, to reduce energy consumption, guarantees that the information that has received is held.
During components of system as directed 11 was in status of support, the electric energy that is stored in the battery 13 only consumed seldom.Therefore, the output voltage of battery 13 descends slower.When the output voltage of battery 13 is reduced to the working point 23 of accompanying drawing 2,16 entrys into service of tertiary voltage testing circuit, the enabling signal that will reset 16a is sent to components of system as directed 11.One receives this signal 16a, and components of system as directed 11 just is reset, and enters the state of the whole functional of halt system part 11.

(embodiment 2)
The circuit structure of second embodiment of accompanying drawing 3 expressions selective call receiver of the present invention.In accompanying drawing 1 and the accompanying drawing 3, similarly part is with identical numerical code expression, to avoid the repeat specification to similar portions.So, the part that those and accompanying drawing 1 are inequality below will mainly be described in the accompanying drawing 3.
From accompanying drawing 3 obviously as seen, the difference of the embodiment of present embodiment and accompanying drawing 1 is: additional provide one by the conversion control circuit 17 of judging that signal 11a is controlled, judged that signal 11a can judge having of information in the storage devices 12 or the state of nothing and storage device 12 obtains by components of system as directed 11.Conversion control circuit 17 is selected one as the voltage that starts the low pressure alert action from two input voltages, thereby prolongs the apparent lifetime of battery under the situation that does not need support information.In other words, low pressure alarm enabling signal 14a is from first voltage detecting circuit 14, and replenishment system enabling signal 15a is sent to conversion control circuit 17 from second voltage detecting circuit 15, and the output signal of conversion control circuit 17 is sent to components of system as directed 11.
The operation principle of second embodiment below is described.When the output voltage of battery was higher than the represented voltage in working point in the accompanying drawing 2 21, present embodiment can normal running, and the decline of the output voltage of battery 13 as shown in Figure 2.When the output voltage of battery 13 is reduced to the working point 21 of accompanying drawing 2, the first voltage detecting circuit entry into service, 14a is sent to components of system as directed 11 by conversion control circuit 17 with low pressure alarm enabling signal.Components of system as directed 11 1 receives this signal 14a, can begin just to judge whether information has been stored among the storage device 12 and the state of storage device 12.Needing under the situation of support information, components of system as directed 11 receives the signal 14a from first order voltage detecting circuit 14, so components of system as directed 11 starts the low pressure alert action.On the other hand, do not need under the situation of support information in components of system as directed 11 judgements, conversion control circuit 17 is controlled by components of system as directed 11, thereby makes signal 14a invalid, and components of system as directed 11 is carried out operate as normal.
Needing under the situation of support information, the operation of present embodiment is identical with first embodiment.Correspondingly, the operation of present embodiment in the case is omitted.
In addition, under the situation that does not need support information, the electric energy that is stored in the battery 13 is consumed, and the output voltage of battery 13 descends.When the output voltage of battery 13 is reduced to the support of the information shown in the working point 21 operation start voltage V in the accompanying drawing 2
2The time, 15 entrys into service of second voltage detecting circuit, and transmission information is supported operation start signal 15a.When signal 15a was sent to components of system as directed 11 by conversion control circuit 17, components of system as directed 11 was carried out the low pressure alert action first, sent voltage decline alarm.Subsidiary say one, when need be in the information in the support storage device sometime between working point 21 and the working point 22, components of system as directed 11 will start the low pressure alert action constantly at this.
When components of system as directed 11 remained on the state of the information of carrying out support operation or low pressure alert action, the output voltage of battery 13 continued to descend.When the output voltage of battery 13 was reduced in the accompanying drawing 2 system reset starting resistor shown in the working point 23, the entry into service of tertiary voltage testing circuit transmitted output signal 16a.Just reset when components of system as directed 11 receives this signal 16a, the whole functional of components of system as directed 11 stops.
This shows, the advantage that second embodiment not only has first embodiment and had, and also have the another one advantage, that is: under the situation that does not need support information, utilize conversion control circuit can prolong the apparent lifetime of battery.In these cases, select voltage V by conversion control circuit
2Rather than voltage V
1As low pressure alarm starting resistor, thus the apparent lifetime of prolongation battery.
From the foregoing description as seen, according to the present invention, the output voltage of battery can be detected under a plurality of level to the tertiary voltage testing circuit by first.Therefore, components of system as directed can be guaranteed the carrying out of low pressure alert action and information support operation, and is irrelevant with the decline of cell output voltage.In addition, by need judging whether support information, the life-span of battery is prolonged.
