Abstract

The utility model discloses a position detecting block using a wireless radio frequency coder. The position detecting block comprises a casing (4) and a wireless radio frequency coder (8), wherein, a projection with a round hole (1) is respectively formed at two ends of the casing (4); a locating hole I (2) and a locating hole II (3) matching with two locating shafts of an anti-misoperation key are formed on the casing; a coding groove (5) is formed at the bottom part of the casing (4) and corresponds to the position of a code reading module of the anti-misoperation key; the wireless radio frequency coder (8) is installed at the bottom part of the coding groove (5); and a coding baffle (7) is arranged on the wireless radio frequency coder and fixed on the casing (4). The position detecting block is installed on devices such as isolators, earthing switches and the like, and is matched with an installed padlock, so as to achieve the function of detecting the device status, and enable the type of anti-misoperation systems stricter; and the position detection block is installed on the devices such as switches so as to ensure complete on-site inspection and avoid poor switching operation.

Description

A kind of position inspection piece that uses the less radio-frequency coding

Technical field

The utility model relates to the device that is applied in the operation of electric power system microcomputer anti-error, especially a kind of position inspection piece that uses the less radio-frequency coding.

Background technology

At present microcomputer anti-error operating system has been widely used in the transformer station, power plant of electric power system.Lockset in the microcomputer anti-error operating system mostly is padlock greatly, and this type of lockset makes that because not possessing the device location acquisition function five anti-control procedures are not very tight, can not carry out next step operation etc. just operate to put in place as equipment.In addition, in some cases, might forget the site inspection virtual condition behind operating personnel's remote control switch, if switching manipulation is not in place, and operating personnel continue the operation of back, probably cause misoperation.

Summary of the invention

For overcoming the deficiency that prior art exists, the utility model provides a kind of position inspection piece that uses the less radio-frequency coding, is used for checkout equipment position or equipment and reads sign indicating number in the electric power anti-misoperation system.

For achieving the above object, the technical solution of the utility model is as follows:

Include housing and less radio-frequency coding, the two ends of described housing respectively are provided with a round-meshed projection, on housing, be provided with matched location hole I of two locating shafts and location hole II with anti-error key, read the corresponding position of yard module at the bottom of housing and anti-error key and be provided with the coding groove, the less radio-frequency coding is installed in the coding trench bottom, be provided with coding baffle plate and being fixed on the housing above it, when the less radio-frequency coding damages, can pull down replacing.

The utility model be installed in disconnecting link, on the equipment such as cutter, cooperate with the padlock of installing, can realize the equipment state measuring ability, make the type anti-misoperation system tighter; Be installed on the equipment such as switch, behind operating personnel's remote control switch, need hold anti-error key and read coding to the scene and could continue the back operation, guarantee that site inspection does not pass into silence, prevent switching manipulation situation not in place.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a schematic bottom view of the present utility model;

Fig. 3 is a generalized section of the present utility model;

Fig. 4 is an application schematic diagram of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail:

As Fig. 1, Fig. 2 and shown in Figure 3, housing 4 approximate rectangular blocks, respectively be provided with a semicircle projection that has circular hole 1 at the two ends of housing 4, on housing 4, be provided with matched location hole I2 of two locating shafts and location hole II3 with anti-error key, read the corresponding position of yard module at the bottom of housing 4 and anti-error key and be provided with coding groove 5, less radio-frequency coding 8 is installed in the bottom of coding groove 5, adopt one piece of screw baffle plate 7 of will encoding to be fixed on the housing 4 above it, to prevent that less radio-frequency coding 8 from coming off, when less radio-frequency coding 8 damages, can pull down replacing.

As shown in Figure 4, the circular hole 1 that the utility model is passed housing 4 two ends respectively with two screws be fixed on disconnecting link, on the drive link 9 of equipment such as cutter, and establish a baffle plate 10 in its front, prevent that anti-error key from reading its coding, when disconnecting link, cutter when operating the another one state, drive link 9 rotates to an angle, the novel certain angle that also rotated of this use, and baffle plate 10 stops that no longer anti-error key reads its coding.Anti-error key has been read coding and has just been judged device location.

The utility model is installed on the equipment such as switch, the appropriate location of the equipment of being fixed in uses the same method, when two locating

shafts

11 and 12 of anti-error key are inserted in two location holes 2 of the present utility model and 3, read yard module and can aim at the less radio-frequency coding, anti-error key can be read up coding.Behind operating personnel's remote control switch, need hold anti-error key and read the operation that coding could continue the back to the scene, operating personnel can look over the virtual condition of switch when reading sign indicating number, thereby can prevent switching manipulation situation not in place.

Claims

1, a kind of position inspection piece that uses the less radio-frequency coding, it is characterized in that, include housing (4) and less radio-frequency coding (8), the two ends of described housing (4) respectively are provided with a projection that has circular hole (1), on housing (4), be provided with matched location hole I of two locating shafts (2) and location hole II (3) with anti-error key, read the corresponding position of yard module at the bottom of housing 4 and anti-error key and be provided with coding groove (5), less radio-frequency coding (8) is installed in coding groove (5) bottom, is provided with coding baffle plate (7) above it and is fixed on the housing (4).
