Description
Technical field
The present invention relates to the safety monitoring system under coal mine, specifically a kind of mine power supply monitoring system.
Background technology
Due to the particularity of mine operation, under all working equipments and monitor well, the various monitoring equipments of environmental factor are all to be powered by civil power.Once city, breaking down or have a power failure, can cause the stagnation of mine operation, is particularly huge on the impact of subsurface environment monitoring equipment and data transmission set, even can cause the accidents such as serious sudden accident or casualties.In addition, the direct current that the required working power of the enviromental monitoring equipment using under these mines and data transmission set is low volt, need to carry out step-down conversion by civil power.
In recent years, fast development along with power technology, industry spot is more and more higher to the intelligent requirements of power supply, power supply monitoring system is as a part that realizes power-supply system intelligent requirements, also obtain applying more and more widely, in order to guarantee the normal operation of monitoring equipment and data transmission set, when break down power-off or when fluctuation occurring can not meet power supply needs of civil power, can also carry out homework of supplying power to it.
Summary of the invention
The present invention will solve the problems of the technologies described above, and a kind of mine power supply monitoring system is provided, and has guaranteed the monitoring equipment that uses under mine and the normal power supply work of data transmission set.
Technical scheme of the present invention is:
A kind of mine power supply monitoring system, comprise civil power and the power supply unit transmitting for environment measuring, signal, the output of described civil power is electrically connected to power supply unit by pressurizer, power supply changeover device, the input of described power supply changeover device is electrically connected with storage battery, the output of described storage battery is electrically connected with monitoring equipment, and the output of described monitoring equipment is connected with pressurizer, power supply changeover device respectively; The output of monitoring equipment is by network communication module and the PC radio communication of being located at Surveillance center.
Further, the output of described civil power is connected with pressurizer by current rectifying and wave filtering circuit.
Further, described monitoring equipment comprises single-chip microcomputer, and the input of described single-chip microcomputer is electrically connected to voltage, the voltage sensor of electric current, current sensor for detection of civil power respectively; The output of single-chip microcomputer is connected with switch module; Described monitoring equipment is connected with stabilizer, by switch module, is connected with power supply changeover device by single-chip microcomputer.
Further, in order to make people find that in time civil power breaks down or power-off, the output of described single-chip microcomputer is connected with alarm.
Further, the output of described voltage sensor, current sensor is all connected with single-chip microcomputer by A/D modular converter.
Power supply monitoring system of the present invention adopts 2 kinds of powering modes to the power supply unit for environment measuring, signal transmission: Alternating Current Power Supply and direct current supply.The in the situation that of civil power normal power supply, directly adopt Alternating Current Power Supply pattern to power to power supply unit; When civil power power-off or fluctuation can not meet more greatly power supply unit to the requiring of power supply, just need to carry out the automatic switchover of powering mode, by power supply changeover device, be converted to storage battery it is carried out to direct current supply.Guarantee the normal operation of monitoring equipment for mine and data transmission set, thereby ensured the safety of mine operation.
Current sensor and voltage sensor are set on line and gather respectively its voltage and current value, after then changing by A/D, send in single-chip microcomputer.Single-chip microcomputer is processed gathered data, and judges whether to exceed adjusting range.If within adjusting range, single-chip microcomputer outputs signal to pressurizer civil power is carried out to voltage stabilizing control output power supply; If exceed adjusting range, single-chip microcomputer outputs signal to switch module, and switch module orders about the switching that power supply changeover device carries out AC DC electric, orders about storage battery it is powered, and realizes overvoltage, overcurrent protection.Meanwhile, single-chip microcomputer output alarm signal makes alarm work, and staff can be fixed a breakdown or other emergency measuress in time; And by measured to voltage, current value data by the wireless PC that uploads to remote monitoring center of network communication module, thereby the remote control function of realization.
