The computer monitor for the environment protection equipment operation state has the advantages of intelligence, power failure protection, accuracy and error free, etc., and can be used for the departments of the environmental protection and other departments needing monitoring the operation states of the equipment.

Description

Computer monitor for environment protection equipment operation state

The utility model is that a kind of multichannel that can realize detects, writes down, shows and add up the intelligent apparatus of environmental protection equipment running status in real time.

At present, the treatment facility of unit sewage such as the enterprise that environmental administration monitored, biotope, hospital, hotel, waste gas, flue dust does not generally all have the installation and operation state monitoring apparatus.And the operation conditions of these equipment, general operating personnel's manual record by this unit, the way of being added up by the statistician draws then, not only loaded down with trivial details but also be subjected to relevant peopleware and safeguard our unit's interests and the influence not recording faithfully and add up, can not definitely reflect and influence environmental improvement by equipment operation condition.The utility model " operation hours monitor " of on May 6th, 1992 bulletin only can add up operation hours, concrete year, month, day, hour, min that can not the recording unit operation; Can not monitor multiple devices simultaneously; The operation ratio of equipment is still by artificial calculating.Because lack detailed first-hand record, the data of its statistics still can not be avoided mistake.Thereby the growing needs of protection that can not conform.

The purpose of this utility model is to overcome above-mentioned defective of the prior art and provides a kind of intelligent multichannel that can realize to detect, write down, show and add up the device of environmental protection equipment running status automatically.Because this device can provide the detail record and the statistics inventory of year, month, day, hour, min, work shift, accumulated running time and equipment operation rate that multiple devices open, stop simultaneously, and completely under power-off condition preserve the data that institute writes down and adds up, thereby stopped mistake, solved the variety of issue that exists by manual record and statistics in the prior art, reflected the environmental protection equipment operation conditions truly, the needs of environmental administration's supervision have been satisfied effectively, perfect means of administrating on laws.

The purpose of this utility model realizes by following approach: the utility model is made up of necessary components and parts such as single chip microcomputer, program storage, microprinting head, semiconductor, detecting units.Wherein detecting unit is made up of shunt, connection terminal, isolating transformer and zero cross detection circuit.Its effect is exactly equipment running status to be become pulse signal for the main frame collection.It is characterized in that with the shunt string in the equipment major loop when device start and operation, 75 millivolts of alternating voltages being arranged at the shunt two ends, this voltage induces about 100 millivolts alternating voltage through isolating transformer at pair level two ends.This voltage waveform detects through zero passage and is shaped as corresponding rect.p., detects for main frame.When equipment shuts down, this detecting unit output high level.Main frame is handled the back storage with the data of being gathered, and drives the detailed bill about record and statistics such as each equipment running status data of printhead prints, power off time, equipment operation rate simultaneously.Main frame is also controlled contents such as charactron demonstration time.

The utility model has following advantage than prior art:

1. can monitor automatically and record the multiple devices running status simultaneously.

2. detailed record and statistics inventory is provided.

3. has power-down protection.

4. degree of accuracy height.Clock per 24 little time errors were less than 1 second.The record running status is accurate to branch.

Accompanying drawing one is a theory diagram of the present utility model.Accompanying drawing two is the utility model software block diagrams.Accompanying drawing three is circuit diagrams of the utility model detecting unit.

Do to implement to further specify below in conjunction with accompanying drawing:

It is other that the utility model is installed in monitored equipment control box (plate).Power supply lead wire meets AC220V.Detect two of every equipment of lead-in wire, be connected on this equipment major loop shunt two ends.(the major loop diverterless should insert corresponding shunt, as " sensor " of detecting unit.) course of work is as follows:

Energized by key is arranged, is imported at that time year, month, day, hour, min, monitored equipment platform number, work shift successively.By function key, the utility model is promptly started working, and prints the initial working time.When device start, just there are 75 millivolts of alternating voltages at string shunt two ends in major loop, this voltage is sensed through the elementary winding of isolating transformer and is paid winding, become from the zero level to the high level through the transistor shaping, the pulse signal of such waveform from the high level to the zero level again, this signal was detected repeatedly by main frame in time rating, determine errorless be monitored equipment start just write down start-up time and the start-up time of printing inventory.When equipment shut down, detected signal was a high level, write down and print stand-by time this moment.When multiple devices are arranged, the same circuit working of multichannel is just arranged.The data instant of its record enters internal memory, counts the individual device operation ratio.When having a power failure, the outage detection signal makes main frame enter the work of power-fail interrupt protection subroutine, and complete machine enters the leisure state, keeps clock normally to move when whether detection powers on.After powering up, this machine enters normal operating conditions, repeats above work.When the staff of environmental administration superintended and checked, as long as by " printing " key, the data of various records and statistics were got complete inventory by printer.Do not need manually to calculate, stopped mistake, realized robotization.

Claims (1)

1. A kind of environmental protection equipment running status computer-controlled monitoring instrument of forming by single chip microcomputer, program storage, microprinting head, nixie display, button and detecting unit, its detecting unit is made up of shunt, isolating transformer, resistance, electric capacity, crystal diode, transistor, it is characterized in that with as the shunt string of " sensor " in the equipment major loop.
