In particular, the present invention relates to a wireless receiver with a battery life detection function (hereinafter abbreviated as receiver) having a battery life detection function.

Regarding a receiver used in a radio paging system that calls a specific person from among a plurality of people carrying a receiving device, the receiver detects the voltage of the battery that is the power source, and detects the voltage at a preset first detection level of 8 or lower. When the battery voltage drops further and falls below the preset second detection level B, the receiver saves the data held by the receiver to memory and stops functioning. By providing an internal means to stop all functions other than those used to notify the user of the situation, the reception system notifies the end of battery life, reduces current consumption, and enables reactivation when the battery voltage returns to normal due to recharging, etc. It provides an opportunity for

を用いて幸に知する方法が取られている。In portable mobile terminals that operate only on batteries, such as receivers used in radio paging systems that individually call multiple radio receiving devices using a paging signal transmitted from a radio transmitting device, the power consumption needs to be kept low. In receivers that are sometimes required to be smaller and thinner, there are restrictions on the size of the battery, making it impossible to install a large-capacity battery. Therefore, when a secondary battery is mounted, it is necessary to frequently charge the battery, and a method such as a display is used to notify the battery voltage drop.

可能となるという欠点を有していた。When using a system like the one above to have a large number of people carry receivers for an indefinite period of time and call a specific person, determine the battery capacity by assuming the time until recharging and the average power consumption until recharging. However, by the time it is time to recharge, the receiver is not called and continues to receive data, and the voltage of the seven batteries drops, and although a voltage drop is displayed, there is no need for the user to do anything about it, and eventually the reception sensitivity deteriorates and the function deteriorates. This has the disadvantage that the battery stops and cannot be restored even if it is charged, such as when data is stored in the internal volatile memory.

停止した事を表示し、機能を停止するようにした。In order to solve the second problem, the present invention provides two detection levels for comparison with the battery voltage, and when the battery voltage falls below detection level 8, it indicates a decrease in the battery voltage. The contents are displayed, and if the detection level falls below detection level B, the data held at that time is saved in the storage section, and then a message indicating that the function has stopped is displayed and the function is stopped.

を抑える事が出来る。Furthermore, when the battery voltage drops, the data is safely evacuated and the power supply to the receiving section, which accounts for a large portion of the total power consumption, is stopped, so the current consumption can be suppressed after the battery voltage drops.
