摘要： PROBLEM TO BE SOLVED: To accurately measure the abrasion of a trolley wire without requiring skill of a measurer. SOLUTION: The light from a luminous element 1 is made a parallel light 4 with a lens 2, irradiated to a trolley wire 3 received with a CCD sensor 5 and the shadow of the trolley wire 3 by the parallel light 4 is taken in a CPU 9 by way of LPF 7 and A/D converter 8. This measurement and take-in is conducted with a specific time period, the minimum value is stored in the memory in the CPU 9, the present measured value is compare with the stored minimum value at every measurement. When the present measured value is small, the measured value is renewed and stored as a new minimum value.

摘要： PROBLEM TO BE SOLVED: To provide a connection type sensor system capable of automatically allocating an address of a sensor unit string without separating a communication unit from a network by resetting only a power source of the sensor unit string with the power source of the communication unit turned on. SOLUTION: Sensor units are respectively provided with an automatic address allocating means which allocates a prescribed address to a self-machine and subsequently transmits the prescribed address as a reference address to an adjacent machine when the self-machine is recognized as an end part machine of a particular side of a sensor unit string by communication with both adjacent machines right after power source resetting, meanwhile, waits for a reference address to arrive from an adjacent machine, calculates an address of the self- machine on the basis of the reference address to allocate the address and also transmits the address as a reference address to the adjacent machine of the opposite side when the self-machine is recognized as a halfway machine of the sensor unit string or the end part machine of the other side, and the connection type sensor system is furthermore provided with a sensor string power source resetting means for resetting the power supply of the sensor unit string while keeping the power source of the communication unit turned on.

摘要： PROBLEM TO BE SOLVED: To reduce program preparing time by executing a comparing instruction based on comparing object data information, comparing value information and outputting destination information showing an outputting destination to be outputted as the signal of ON/OFF of the contents of a comparing result so as to facilitate program description. SOLUTION: A CPU 11 keeps the execution of a processing program stored in a user memory 12 and judges whether a contact point instruction is turned on based on flag information stored in an I/O memory 13. The CPU 11 reads out a comparing instruction at the time of judging the contact point instruction is turned on by flag information stored in the memory 13. In this case the CPU 11 executes the comparing instruction described in the processing program based on comparing object input channel number, comparing value information showing the comparing value and outputting destination information showing the outputting destination to be outputted as the signal of ON/OFF of the contents of the comparing result. Thus, description of the program is facilitated.

摘要： PROBLEM TO BE SOLVED: To facilitate the filling of a program and to shorten program generation time by executing an output delay instruction filled in the processing program based on delay time information and output destination information. SOLUTION: When a contact point instruction 51 whose contact point number is '00001' is turned on, the output delay instruction (DOUT 01) 52 is started. When five seconds pass, the output delay instruction (DOUT 01) 52 outputs an ON-signal to a contact point instruction whose contact point number is '00101'. When the ON-signal is outputted to the contact point instruction whose contact number is '00101' and a contact point instruction 62 whose contact point number is '00002' is changed from OFF to ON, the output delay instruction (DOUT 02) 62 is started. When eight seconds pass, for example, the output delay instruction (DOUT 01) 52 outputs a signal changing the setting point instruction of '00101' from 'ON' to 'OFF'.
