Description

For the protection of the padlock with monitoring switch

The present invention relates to for the protection of the padlock with monitoring industrial equipment switch.The invention still further relates to the protection for the industrial equipment switch and the monitoring system that comprise at least one padlock.

The concrete range of application of padlock is the employment security field.Exist to industrial equipment and overhaul relevant risk, for example, the risk relevant to the maintenance of producing machine, the unexpectedly startup again of industrial planning still stopped in order to carry out service work when continuing when service work.Can cause great danger to the service engineer thus.Therefore usual is that the switch that the service engineer will be associated with industrial equipment in whole service work process moves to open position and this switch is fixed on to this position, and this switch is directly stopped or the access of this switch is blocked.Described switch is generally the energy supply switch, for example the energy supply switch of the main electronic switch of control device or industrial equipment power supply device (for example power switch box).Alternately, described switch can be the valve of for example controlling gas piping or liquid line.

In order effectively to avoid industrial equipment by other people accidental activation, each service engineer padlock was suspended on to described switch before starting working or the retention device that is associated with this switch on and pin this padlock.Therefore this switch is fixed on open position, that is, this switch can not unexpectedly be retracted on-position by other people.When the service engineer finishes its work, this service engineer discharges its padlock by the padlock release and from this switch again.Each service engineer has the independently padlock (or a plurality of oneself independently padlock) with oneself usually.

This process also is called as locking (English: lockout(locking)).Therefore the padlock used is called as the locking lock.Document US5,449,867 show by padlock and protect the electric rocking pole type switch.From document US3,171, the 908 known positions of protecting rotary switch by padlock.

Therefore, a plurality of service engineers can stop and release-push again independently of one another, for example, so a plurality of female part (eyelet) can be arranged on switch, sentence and hang a plurality of lockings locks.This can be for example from document 6,388, and 213 learn.Can use safety tongs if only arrange one for locking the female part of lock, its be suspended on switch or each eyelet of the retention device that is associated in and there are a plurality of eyelets of the suspension for each padlock.Only when last padlock removes from safety tongs, safety tongs just can remove from switch, makes this switch can again reach on-position.For example, from document US6,396,008, US5,365,757 and US3,667,259 can be known this for using the safety tongs at the power switch box place.

About the above-mentioned protection to the industrial equipment switch, knownly with plastic casing, equip locking lock, and latch hook remains on lock housing body place movably and lock gall is arranged in the lock housing body.Lock gall optionally enters lock position from open position, for example after latch hook is suspended in the eyelet of switch, latch hook is locked to the lock housing body.By utilizing plastics to form the lock housing body, thereby produced light especially padlock, this is to being favourable as the locking lock, because the service engineer carries a plurality of locking locks sometimes simultaneously.Plastic casing also can play the electric insulation effect of expectation.By utilizing plastic casing, can also utilize especially simply the color mark padlock in addition.With the lock housing body be made of metal, compare, the low stability of plastic casing is not the major defect in locking lock because padlock only for the protection of switch in case the purpose activated unintentionally, rather than for example for stealing protection.This locking lock with plastic casing is for example from document US7, and 278,283 and US5,755,121 is known.These are all the examples of simple pure Mechanical ring latch.

The purpose of this invention is to provide padlock and corresponding protection system, it allows to utilize simple design to protect reliably and monitor the industrial equipment switch.

The padlock of the feature of this purpose by thering is claim 1; especially by the padlock for the protection of with monitoring industrial equipment switch, realize; should there is the lock housing body be made of plastics for the protection of the padlock with monitoring industrial equipment switch; also there is latch hook and lock gall; latch hook remains on lock housing body place movably; lock gall is arranged in the lock housing body and optionally from open position, enters lock position latch hook is locked to the lock housing body, wherein in the lock housing body, also is provided with R FID transponder (RFID-Transponder).

When reading device that use is associated, can check and record each locking lock by the RFID transponder in the housing that is arranged on the locking lock in simple mode and whether in preset time, be arranged on the industrial equipment switch and sentence and protect this switch.For this purpose, because can be used as independently independent unit, inserts in padlock, so the padlock used can have simple Machine Design by the RFID transponder.Therefore padlock can have the pure mechanical locking function irrelevant with the electronic control system of RFID transponder.Because the RFID transponder is arranged in plastic casing, so can carry out radio communication with the reading device be associated not having substantially in noisy situation.Simultaneously, the RFID transponder is protected reliably in order to avoid damages and pollute.This is an importance at padlock in use as the locking lock, for example, because if when padlock is arranged on industrial equipment switch place and carries (hang on tape) by the service engineer when not in use, padlock can be subject to large pulling force due to wind and/or wearing and tearing.

The RFID transponder can be arranged in the lock housing body in every way.For example the lock housing body can form the outer covering piece that wherein is integrated with the RFID transponder, especially by overcasting (Umgiessen) or post forming (Umspritzen).Alternately, for example the RFID transponder can be received in the lock housing body, as will be described below releasedly.

The RFID transponder is to be scheduled to reception and the dispensing device that radio frequency receives request signal and therefore sends predetermined identification signal (for example being coded in the identification number in radio signal).This process is called as RFID(Radio-Frequency Identification, radio frequency identification).For this purpose, the RFID transponder has at least one antenna, be attached to the electronic circuit of antenna and the nonvolatile memory of storing predetermined identification number wherein.If the reading device be associated utilizes suitable frequency produce the electromagnetism alternating field and send it to RFID transponder (request signal), the electromagnetic energy of the antenna reception alternating field of RFID transponder, the transmission of above-mentioned like this identification signal be triggered (passing through antenna).For this purpose, the electronic circuit of RFID transponder is not to have any oneself energy supply, but can obtain from the alternating field received the electric energy needed.The identification signal of output is decayed and is imprinted onto in the alternating field of generation by field by reading device, makes reading device the identification signal of RFID transponder can be decoded.This RFID transponder for example can be from document US7, and 205,899 learn.

By read with the identification signal of the RFID transponder that locks combination simply mode find and/or record which locking lock (corresponding to specific service engineer) and be fixed to the industrial equipment switch in preset time.Can also detect a plurality of RFID transponders by a reading device be associated in this simultaneously, that is, can determine simultaneously and/or record the existence of a plurality of different RF ID transponders or locking lock.The monitor signal (the standby possibility of monitoring switch state) that with switch or the control device that is associated with each industrial equipment, can there is in addition the information (for example identification number and date/time) based on obtaining by reading device.Which locking lock in when be arranged on industrial equipment switch place separately can be alternately or record additionally, for example, for the situation (accident clarification, responsibility) of industrial accident.

According to favourable execution mode, in the lock housing body all sides of RFID transponder all by around.Therefore guaranteed that the especially effectively protection of RFID transponder is in case mechanical damage and/or pollution.Preferably, all sides of RFID transponder are all by for example, around being to cooperate with another part of padlock by the lock housing body with especially having other housing parts (inner housing or housing parts) realized.

According to another execution mode, the lock gall of padlock has longitudinal shape, and its longitudinal axis is usually corresponding to the rotation of the rotatable lock core of lock gall.Lock gall can be configured to for example lock core, especially interchangeable lock core.In this embodiment, the RFID transponder is arc with respect to the longitudinal axis of lock gall.In other words, RFID transponder (in normal plane of longitudinal axis) in cross section extends with crooked shape around lock gall.Therefore caused the particularly advantageous angle character of RFID transponder, that is, the RFID transponder can cooperate with the reading device be associated in very large angular range.Therefore, no matter the front side of padlock or trailing flank, to the RFID reading device, all can be realized the reliable communication with the RFID reading device be associated.Thus, the lock gall usually be made of metal is proved to be and is not to disturb, because lock gall can be arranged in formed by the RFID transponder arc, the RFID transponder can completely or partially be centered around around lock gall.

The RFID transponder especially can extend along at least a portion length of lock gall with along at least a portion edge of lock gall.In this, the RFID transponder needn't contact lock gall, but preferably is arranged on the contrary with lock gall (at the longitudinal axis with respect to lock gall in the radial direction) spaced apart.Therefore particularly preferred reception and the transfer characteristic of RFID transponder have been realized, and the mode of the unit that can " surround (gewiekelten) " realizes RFID transponder holding in the lock housing body, in the simple structure mode, be positioned at around lock gall and there is minimum space requirement.

Advantageously, the RFID transponder is arranged to lock gall spaced apart.Investigation shows, when the RFID transponder does not directly contact lock gall and while being arranged on the contrary from lock gall specific interval place, realized the particularly preferred angular characteristics of RFID transponder.As mentioned above, when the RFID transponder is arc with respect to the longitudinal axis of lock gall, this is especially applicable.
