Abstract
The utility model relates to an automatic switching device of wireless telephone set for chargeable battery and external power supply in the communication technical field, comprising a detecting device with an external power supply, a control element connecting with the external power supply, a rechargeable battery and the other control element connecting with the battery. The detecting device with the external power supply respectively connects with the I/O control input end of the two control elements via a CPU. The detecting device with the external power supply can detect whether powered down or not to control the on-off of the two control elements and further to control the automatic switchover between the rechargeable battery and the external power supply and the charge of the rechargeable battery. Owing to the battery in the scheme of the utility model is not directly connected with the external power supply and is not always in a charged or a discharged state, so the service life of the battery can be prolonged; due to the short shifting time of the control elements, which is 10<-9> seconds, and the small resistor, the power consumption is low and the continual power supply is realized.
Description
Technical field
The utility model relates to radio apparatus chargeable battery and the dispatch from foreign news agency automatic switching control equipment in a kind of communication technical field.
Background technology
In existing radio apparatus, dispatch from foreign news agency directly is connected with battery, and battery is in charging and discharging state constantly, reduces the useful life of battery.Or switch control circuit complexity, and price height with relay.
Summary of the invention
The purpose of this utility model is existing by dispatch from foreign news agency in the radio apparatus and the direct-connected shortcoming of battery in order to overcome, in order to improve the utilance of battery, minimizing provides a kind of circuit radio apparatus chargeable battery simple, low in energy consumption and dispatch from foreign news agency automatic switching control equipment because of changing battery to the trouble that the attendant brings.
The technical solution of the utility model is: the radio apparatus chargeable battery comprises that with the dispatch from foreign news agency automatic switching control equipment outer electric detection means, the control element that is connected with external power, rechargeable battery and connected another control element, outer electric detection means are connected with two control element I/O control input ends respectively by CPU, whether detect power down by outer electric detection means, control two control element break-makes, and then the automatic switchover between control external power and the chargeable battery and the charging of chargeable battery.
Because battery directly is not connected with external power in the scheme of the present utility model, battery is not to be in charging and discharging state constantly, and this can make prolong the useful life of battery, again owing to being 10 by control element weak point switching time
-9Second level, resistance is little, and is therefore low in energy consumption, can realize not having discontinuous power supply.
Description of drawings
Fig. 1 is radio apparatus chargeable battery and dispatch from foreign news agency automatic switching control equipment electrical schematic diagram.
Embodiment
By shown in Figure 1, radio apparatus chargeable battery and dispatch from foreign news agency automatic switching control equipment comprise outer electric detection means 1, the control element 3 that is connected with external power 2, rechargeable battery 4 and connected control element 5, outer electric detection means 1 by CPU respectively with control element 3, the I/O control input end P1.2 of control element 5, P1.1 is connected, control element 3 and control element 5 are power field effect pipe, its model is: XP162A12A6PR, it has the grid G as the I/O control input end, source S, drain D, the S utmost point of control element 3 is connected with external power, the S utmost point of its D utmost point and control element 5 is connected, and the D utmost point of control element 5 and the positive pole of chargeable battery are connected.When dispatch from foreign news agency, the G low level very that outer electric detection means signals and makes control element 3 by CPU makes the D end and the conducting of S end of control element 3, and the connection of functional devices such as external power and module is powered.Simultaneously, the G that makes control element 5 is high level very, makes its D end and S hold and end, and powered battery partly is disconnected.When the dispatch from foreign news agency power down, the G high level very that outer electric detection means signals and makes control element 3 by CPU makes the D end of control element 3 and S end end the disconnection of functional devices such as external power and module.Simultaneously, the G that makes control element 5 is low level very, makes its D end and S hold conducting, and powered battery partly is switched on, and switches to powered battery.When battery charge, the I/O control input end of two control elements is low level simultaneously, the equal conducting of control element, and after charging finished, the I/O control input end of control element 5 was a high level, recovered dispatch from foreign news agency normal power supply state.Because of the control element reaction time is 10
-9Second, level was connected to filter capacitor C in addition on external power
4, therefore, when existing, dispatch from foreign news agency has electric weight, and this device can realize not having discontinuous power supply.
