Specific embodiment

The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.

Embodiment

As shown in figure 1, the utility model discloses a kind of new medicinal intelligent socket box, including socket casing 1, distribution System and power supply monitoring module three parts composition.Wherein socket box also includes the equipotential terminal block 5 being fixed on casing；Match somebody with somebody Electric system is constituted by distributor breaker 2, with electric lead 3 and socket box 4；After power supply monitoring module includes distribution system power down, use Supervise in the back-up source 6 of monitoring modular work, the Medical power for realizing electric leakage, down Monitor Unit, and fault alarm is maintained Survey unit 7 and residual current transformer 8.

As shown in Fig. 2 Medical power monitoring unit 7 includes the central processor unit 9 for controlling other modules, it is used for The power module 10 of power supply is provided to other modules, for monitoring the residual current of main inlet wire and each branch road residual current Survey module 11, the down Monitor Unit module 12 of monitoring socket case distribution system power-down state, the storage preserved to configuration parameter Module 13, externally carries out the communication module 14 of data exchange, and is used for producing corresponding acousto-optic report when normal operation and failure The operation of alert signal and failure indication module 15.

In the utility model, Medical power monitoring unit 7 is the nucleus module of socket box, for monitoring the leakage of distribution system Electricity and power-down state.When distribution system is normally run, monitoring unit 7 is powered by distribution system, is disappeared by fire-fighting power supply module Anti- power module is also charged a battery simultaneously.And when distribution system power down, monitoring unit 7 is by fire-fighting power supply module by storing Battery is powered.The CPU 9 of monitoring unit 7 is using 32 chips based on Cortex-M3 kernels.The chip dominant frequency Height, in piece, peripheral hardware enriches, and simplifies hardware design.Central processor unit 9 is used for data acquisition and calculation process, and according to The alarm threshold value that family is arranged carries out contrast judgement, and when certain failure is judged as, control related circuit sends instruction and reports to the police.Electricity Direct current 15V photovoltaic conversions into direct current 5V and 3.3V voltage, are provided suitable power supply for each module by source module 10.Remaining electricity Stream monitoring modular 11 by residual current transformer 8 come the residual current of each branch road of Real-time Collection, after filtering, after signal condition Send the ADC of CPU 9.Down Monitor Unit module 12 is used for the voltage of detecting system, after sampled voltage conditioned The ADC of CPU 9 is sent into, central processing unit for processing and judgement is transferred to.Memory module 13 is used for storage system Configuration parameter and calibration parameter, and failure logging.Communication module 14 is using electrical isolation based on Modbus-RTU agreements RS485 circuits, be capable of achieving Monitoring Data transporting function.Operation includes operation, warning buzzing with failure indication module 15 Device and various malfunction indicator lamp, indicating fault type include：Equipment fault, main road electric leakage, the electric leakage of each branch road and power down instruction etc., Wherein run indicator is green, and malfunction indicator lamp is redness.During failure, the alarm sound of alarm buzzer can pass through noise reduction Button is eliminated manually and is closed.

Operation principle：

Medicinal intelligent socket box is medical space distribution, and medical equipment can the directly power taking from socket box.When certain branch road When having electric leakage, leakage current can be sensed by the residual current transformer 8 of the branch road, senses the secondary current signal Jing for producing CPU 9 is sent into after crossing the sampling conditioning of residual current monitoring modular 11 to be calculated, when calculated residual current When value is more than alarm threshold value set in advance, CPU 9 just drives operation instruction electricity corresponding to failure indication module Road carries out sound and light alarm, indicates that the branch road occurs leak current fault, reminds staff to switch socket in time and notify professional Carry out malfunction elimination, it is to avoid electric leakage and electric shock accidents occur.Alarm sound can be eliminated manually or be closed by noise reduction button, but Could extinguish after the failture evacuations such as alarm lamp need.In the same manner, when generation power down failure is that CPU 9 passes through Pyroelectric monitor module acquisition system voltage, after judging distribution system power down, drives operation to send corresponding with police instruction module Sound and light alarm.Any fault alarm information will be all recorded in memory module 13, and the configuration parameter of system is also stored on In the module, the configuration of system during ensure that start next time will not be changed.All electric leakages that CPU 9 is monitored The real time data of stream, malfunction, and failure logging information can upload to the monitoring of host computer by communication module 14 In system, monitored by monitoring system universal remote.

The foregoing is only preferred embodiment of the present utility model, it should be noted that for the common skill of the art For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
