Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of mobile radio network data terminal unit with Power Supply Monitoring function, comprise power module 1, main control unit 2, standby power supply module 3, detection module 4 and wireless transport module 8, described power module 1 is connected with described main control unit 2, described main control unit 2 is connected by described detection module 4 with the supply module of described standby power supply module 3, and described wireless transport module 8 is connected with described main control unit 2.
Among a kind of embodiment, as shown in Figure 1 and Figure 2, described detection module 4 is the power module testing circuit, the purpose that increases the power module testing circuit is that the electric power thus supplied to described power module 1 detects, and then can automatically warning information be transferred to described main control unit 2 when the power supply state that detects described power module 1 is unusual.Described main control unit 2 is a central processor CPU; Described power module testing circuit is connected with described main control unit 2 by the interface unit of described main control unit 2; Described interface unit comprises interface connector 7 and interface chip 6.Inform central interior processor CPU external power source situation by the power module testing circuit.
The power module testing circuit is realized the working condition of the normal externally fed power supply of DTU system (mobile radio network data terminal unit) is carried out detection, as shown in Figure 4.When externally fed VIN powered-off fault, GPIO will make the level state upset, GPIO is as the universaling I/O port or the exterior interrupt of central processor CPU, give central processor CPU with change notification, central processor CPU can pass through the mobile radio network platform, utilize modes such as short message alarm or data alarm in time to notify the warning information recipient that these device abnormal conditions are handled, thereby reduce the loss that causes unusually because of this device.
But described standby power supply module 3 comprises the lithium battery of charge and discharge; Described standby power supply module 3 also comprises charging module and charging circuit 5; Described charging module is connected with described power module 1 by described charging circuit 5.Lithium battery is responsible for externally power supply power down or is occurred in time providing work capacity for equipment when unusual.When the externally fed power supply power-fail or occur when unusual, the system that can keep continues operate as normal a period of time under the situation of not power down, in time warning information is transferred to described central processor CPU.Simultaneously, the power management of central processor CPU increases the Charge Management to lithium battery, when externally fed just often, realize charge protection, as shown in Figure 3 to lithium battery.Resistance R _ f 1 and Rf2 form the feedback device of LDO, and LDO output clamper behind diode D1 for example is illustrated as 4.2V at the magnitude of voltage of expection, and this magnitude of voltage can adjust Rf1 according to the actual requirements and Rf2 adjusts.When the detection cell voltage was lower than a certain magnitude of voltage, such as 3.3V, central processor CPU control Q1 emitter-base bandgap grading was a low level, and base stage is a high level, and in low level, conducting Q2 realizes constant current charge with the collector electrode clamper.When battery when charging voltage is greater than 3.3V fast, Q2 is cut off in control, and circuit is realized trickle charge to battery realizing the protection to battery by D1, D2 and R3.More than concrete parameter can adjust, it is fixed to come according to the actual requirements.
